Brain Surgery (Craniotomy) - Questions & Answers

Brain Surgery (Craniotomy) - Questions & Answers

Craniotomy is a cut that opens the cranium. During this surgical procedure, a section of the skull, called a bone flap, is removed to access the brain underneath. The bone flap is usually replaced after the procedure with tiny plates and screws.

A craniotomy may be small or large depending on the problem. It may be performed during surgery for various neurological diseases, injuries, or conditions such as brain tumors, hematomas (blood clots), aneurysms or AVMs, and skull fractures. Other reasons for a craniotomy may include foreign objects (bullets), swelling of the brain, or infection. Depending on the reason for the craniotomy, this surgery requires a hospital stay that ranges from a few days to a few weeks.
Craniotomy is any bony opening that is cut into the skull. A section of skull, called a blone flap, is removed to access the brain underneath. There are many types of craniotomies, which are named according to the area of skull to be removed . Typically the bone flap is replaced. If the bone flap is not replaced, the procedure is called a craniectomy.

Craniotomies are also named according to their size and complexity. Small dime-sized craniotomies are called burr holes or keyhole craniotomy. Sometimes stereotactic frames, image-guided computer systems, or endoscopes are used to precisely direct instruments through these small holes.
A craniotomy is performed by a neurosurgeon; some have additional training in skull base surgery. A neurosurgeon may work with a team of head-and-neck, otologic, oculoplastic and reconstructive surgeons. Ask your neurosurgeon about their training, especially if your case is complex.
You will typically undergo tests (e.g., blood test, electrocardiogram, chest X-ray) several days before surgery. In the doctors office you will sign consent forms and complete paperwork to inform the surgeon about your medical history (i.e., allergies, medicines, anesthesia reactions, previous surgeries). You may wish to donate blood several weeks before surgery. Discontinue all non-steroidal anti-inflammatory medicines (Naproxin, Advil, etc.) and blood thinners (coumadin, aspirin, etc.) 1 week before surgery. Additionally, stop smoking, chewing tobacco, and drinking alcohol 1 week before and 2 weeks after surgery because these activities can cause bleeding problems.
After surgery, you are taken to the recovery room where vital signs are monitored as you awake from anesthesia. The breathing tube (ventilator) usually remains in place until you fully recover from the anesthesia. Next, you are transferred to the neuroscience intensive care unit (NSICU) for close observation and monitoring. You are frequently asked to move your arms, fingers, toes, and legs...

Orthopaedic Surgical Instruments and Their Manufacturing

Orthopaedic Surgical Instruments and Their Manufacturing

Orthopaedic implants are artificial devices used to replace or provide fixation of bone. They are used to replace damaged joints. These are actually incorporated and fixed into bones and joints to restore normal function. In other words, orthopaedic implants play the role of joint replacements where the hip, knee, shoulder or elbow has been damaged by injury. These are also used for people who have diseases like osteoarthritis. In such a disease, wear and tear on joints leads to pain and stiffness. Often, these orthopaedic implants need replacing at some point because they tend to wear out after a certain number of years.
You can find a list of Orthopedic Implants Suppliers and manufacturers on online medical surgery directory. This directory provides all the details of these suppliers and manufacturers along with traders, distributors, importers and exporters of orthopaedic equipment.
Orthopedic implants, used to replace damaged joints, are performed only by highly skilled and specialized surgeons. They are made of Titanium alloys for strength and are lined with plastic so as to act as artificial cartilage. Some orthopaedic implants are incorporated into bones while others are pressed to fit and allow your bone to grow into the implant for strength.
The need for Orthopaedic implants arises where non-surgical procedure fails. One important point to remember is that these orthopaedic implants are designed differently by different manufacturers. Manufacturers manufacture orthopaedic implants according to the needs of the surgeons. The biggest advantage of these implants is that they bring back quality of life. They also help in reducing pain and in increasing mobility. The disadvantages include long recovery period, infection and possible malfunction. Also, these implants start wearing out after a few years and require replacement.

Orthopedic Implants Manufacturer has an important role in making a patient's life happier and healthier. Their manufacturing has gone tremendous changes over a period of time. The techniques and tools used to develop orthopaedic implants keep improving. Hence, continuous research and development is required in this field in order to manufacture the tools and equipment required by different surgeons.

Orthopaedic implants are very helpful for people who lose mobility due to some birth defect, accidental injury, or old age. Orthopaedic implants suppliers and manufacturers produce the necessary equipment, supports and replacement joints. This equipment allows patients to have a normal life.

Description: This article talks about various orthopaedic implants tools and equipments. It also talks about the role played by orthopaedic implants suppliers in restoring a patient's life back to normal. Not only this, it also throws light on the advantages and disadvantages of orthopaedic implants.

About Orthopaedic Surgeries using Cancellous Screws

About Orthopaedic Surgeries using Cancellous Screws

Many accidents may result in broken bones. In aged persons, a minor falls may result in broken bones. Bones, when fractured, heals automatically, but unlike other body tissues, they need to be under compressive force to heal properly. Hence, the bones are needed to be held in place properly with the compressive force. In minor cases, if the movement of that body part is restricted, for example, a broken arm, it heals automatically. But for example, a broken hip is something that does not heal automatically. In such cases, surgeries are performed where metallic plates are attached to hold the bone is place using screws. The screws are drilled into the bone, away from the position of the fracture. The plates are attached using cancellous screws or cortical screws. The cortical screws are used in the cortical region, whereas a cancellous screwis used in the cancellous region. Now, the screws may be of different types. They may be threaded fully or partially, they may or may not be self-tapping and self-drilling.
Cortical screws and the cancellous ones have difference in their pitch. The cortical screws have a smaller pitch. Also, they have relatively shallow threads and a much larger outer to core diameter, when compared to the cancellous screws. They also come with a blunt end. This blunt end helps in reducing the soft tissue damage.

A cancellous screw is used in cases when the cancellous bone needs to be fixed. The most common use of them is in the metaphyses of long bones where there is an abundance of cancellous bones. These screws cut more deeply and hence they are much widely spaced. These screws are also much sharper. Hence, they are self-tapping in nature.
The screws are not only used to attach bone plates that allow healing bones, but also, they come to use in case of implanting prosthesis. In orthopaedic surgeries, one of the most common prosthesis that is implanted is the hip replacement prosthesis, or the bipolar prosthesis Hip replacement is needed in a lot of cases. In aged people, it is mainly needed when they suffer from the effects of arthritis. Due to old age, the lubrication between two bones is reduced and hence due to friction, there is pain. The space between the joints can be resurfaced, but a bipolar prosthesis is a permanent solution. In cases of hip replacement, the patient satisfaction varies. But in most cases, it relieves the patient of all pain from arthritis. The prosthesis is made of steel or titanium allows, but if the person suffers from toxicity, then there are other materials that can be used too that provide similar strength and support.

Another prosthesis that is commonly used in a hook plate. A hook plate is simply shoulder prosthesis. These are used in Lateral clavicle fractures and Dislocations of the acromioclavicular joint. Once the bone has completely healed, another surgery is performed to remove this implant that helped the bone to heal.

Scroll Saw Selection - Choosing the Right Saw for Your Needs

Scroll Saw Selection - Choosing the Right Saw for Your Needs

Obviously enough, one of the first things many people want to know when getting started with scrolling as a hobby is what saw to buy. Whether you are looking to purchase your first scroll saw, or you are looking to upgrade to a better one, there are many things to consider. In this article I will attempt to touch on all aspects so that you are able to make an informed decision. I will also make some recommendations based on personal experience and what I feel is the general consensus of the scroll sawyers I have discussed the matter with.
Also, how easy is it to change a blade? Is a tool required for this? Some scroll saw projects have hundreds of holes. This means you have to remove one end of the blade from the holder and thread it through the wood and re-mount it in the holder more times than you can count. Be sure the process is comfortable and relatively easy to do. A saw in which the arm can be raised and which holds itself in this position is most desirable as it makes this process much easier as do tool-less blade holders.

Variable speed: A great many saws offer variable speed and you should not have a problem finding this feature in any price range. Sometimes you will want to slow the blade down just to cut slower, other times you must slow it down to prevent the blade from burning the edges of the wood as you cut. Some scroll saws require belt changing to change speeds. Personally, I would highly recommend a saw an electronic speed control.

Vibration: Vibration is very distracting when cutting and must be kept to a bare minimum. Some saws inherently vibrate more by design. This feature tends to be very much dependent on the cost of the particular saw. Vibration can be reduced by mounting the saw to a stand. A sturdily mounted saw and heavier saw/stand combination will reduce vibration. Many companies offer stands purpose built for their saws.

Size Specifications: Manufacturers often list the maximum cutting thickness of their saws. Since this is always more than 2", you can ignore this as you likely will never want to cut anything thicker than that on a scroll saw.

The depth of the throat however is something you may want to consider if you think you will be cutting very large projects. A small throat will limit how big of a piece you can swing around on the table while you cut. For many this is not a very big deal since it is somewhat difficult and unpleasant to swing around a big piece of wood on a scroll saw. This limit can also be circumvented by the use of spiral blades which don't require the work to be rotated at all.

Table size should also be considered since it is very difficult to work on a project when the majority of your wood is hanging off the side of the scroll saw's table.

Overall Layout: The overall layout of the controls and adjustments of the saw is very important to consider. The power switch, tension lever and speed control ideally should all be located at the end of the saw's arm within easy reach. Since with most scroll work you need to stop and feed the blade through a hole dozens or even hundreds of times, the tension lever and power switch are much more convenient if they are close to the upper blade holders. (Most but not all people undo the blade from the upper blade holder to feed the blade through a hole. Some people however, do find it easier to undo the bottom holder instead.). Also, you may occasionally want to adjust the speed control or tighten the tension while in the middle of a cut so it is good to have these controls within easy reach.

Some people find it easier to use a foot pedal switch rather than the power switch on the saw. Just be sure if do you buy one of these that it is just a simple on/off switch and not a variable speed pedal such as those used on a sewing machine as this can damage some motors.

Price: Of course nearly all of us are limited as to how much we are willing or able to spend on a scroll saw. Buying a good used saw may allow you to get more for your money than buying a new cheap saw. When buying used, however, you are taking a bigger risk and have many additional factors to consider. Is the saw still being manufactured? Will you still be able to buy parts if needed? How much has this saw been used? Is the seller's asking price appropriate? I would generally not recommend buying used unless the saw is in very good condition and the asking price is significantly cheaper than buying the same saw new.

One thing to consider when deciding on the price is that scroll saws are generally a "get what you pay for" kind of tool. Scrolling should be an enjoyable pastime; if you have to fight with a saw that is hard to use or performs poorly, you will not be having fun.

Other considerations: Some other things to look at are the manufacturer's support and service. Will you be able to get the saw serviced locally? How long is the warranty? What is the manufacturer's reputation in general? Does the saw have any extras or special features that you think may be useful?

Some saws come with lamps, magnifiers, stands and most come with dust blowers. All of these features add value to the saw and the dust blower most would consider to be a necessity.

Most, if not all scroll saws come with a hold-down to hold your work down to the table. It is worth mentioning that the vast majority of people, myself included, remove these holders because they feel they are just in the way. As long as you keep downward pressure on your work at all times this is a relatively safe practice. If you do remove the hold-down however, please be aware that you do so at your own risk.
It is my opinion that in order to get a saw that you will be happy with in the long term, you are going to have to be willing to spend at least in the neighborhood of $500. I really think that if you can't afford to spend this much you should seriously think about saving for awhile until you can afford it. That being said, I will mention one saw in the sub $500 range that has recently received some praise.

Porter Cable CB370SS I have not used this saw personally and I cannot speak for its durability however it does look good on paper. All the controls on this saw are conveniently located and it comes with a light and stand. At a retail price of $180, if you absolutely can't spend more, this saw may be a good choice for you.

Dewalt DW788 This is the saw I use personally and I wouldn't hesitate to recommend it to anybody. My particular saw is over 12 years old. It has seen countless hours of use and is still going strong. In that time, the only parts that ever had to be replaced were the blade holders.

In recent times, Dewalt has switched to having its tools built in Asia and quality has suffered slightly. Of course with this transition, the price of this model has come down significantly as well. Dewalt offers a light and stand for this saw but they are usually sold separately. This is a widely used saw and if you have any difficulties, there are plenty of people who are able to offer advice.
A most notable difference between the Excalibur and other saws is that the head of the saw tilts rather than the table. This is a nice advantage if you intend to do a lot of angled cutting. The one feature that I personally am leery about is that you only have a quick release for the tension at the front of the saw's upper arm and the fine adjustment is at the back of the arm. This is a relatively recent change to the saw however I have not seen any negative feedback about this setup. Theoretically, once you have set the fine adjustment, you don't have to adjust it very often and you just need the quick release when undoing/redoing the blade to feed it through your project.
Hegner offers four different models starting at about $700 and going all the way to $2400. The lowest end model "Multimax 14-E" is only single speed which I would definitely stay away from. In my opinion there are several better choices for a comparable or cheaper price. The $2400 industrial "Polymax" model requires belt changing to change the speed which is an inconvenience. Because of this issue and the high price tag, I would only consider this model for a truly industrial purpose. This leaves us with the Mutimax 18-V and 22-V models to consider.

All Hegner saws require tools for blade changes. This fact, in addition to what I would personally consider an inconvenient control layout would make me think twice about a Hegner. That being said, most people who own Hegners are very happy with the quality and usability of their saws. Since I have not personally used one, I will leave this matter for your further consideration if you can afford a saw in this price range.
I hope this article has provided you with enough information to allow you to make the best possible investment of your money so that you can start with or upgrade to a scroll saw that will provide you years of scrolling pleasure.

Reciprocating Saw Reviews - Uses, Blades and Cordless

Reciprocating Saw Reviews - Uses, Blades and Cordless

Some time ago, picking a cordless tool over its cord attached comparable version most likely meant giving up a considerable amount of electrical power. Furthermore, the batteries on cordless tools did not really last very long, making individuals to charge your saw frequently, an inconvenient necessity when it comes to those doing lengthier tasks. Luckily, this has changed in recent years. The cordless tools are now more powerful and they last longer than they have in the past. On top of that, they're significantly more mobile than ever. More good news is the fact that this particular rise in quality has been accompanied by a lowering in price range.
Reciprocating Saw Reviews - Characteristics of Reciprocating Saw Blades

Identifying all the strengths and weaknesses of each saw was a crucial step in our reciprocating saw reviews process. One of the best characteristics of a reciprocating saw is its enormous versatility, because of the large variety of saw blades it can easily be fitted with.

Do you need an instrument that cuts through metal, piping, timber, drywall as well as fiberglass?  With the correct blade, the reciprocating saw can do all of these jobs and more.

There are a variety of blades to pick from (an important step in the reciprocating saw reviews process), the type of blade you choose will be determined by the depth and consistency in the material that an individual wants to cut.

Reciprocating Saw Reviews - (Blades) Dimensions

Reciprocating saw blades can range in length from 2.5 to 12 inches. Know in advance how in depth you would like the cut to be, in order to choose the right length. In regards to width, having a more significant width will certainly decrease wobbling and also bending. The thickness one wants equally depends on what you're want to achieve: most tasks need a thickness approximately .035 inches, although .05 inches is better for the truly challenging jobs.
Blades may possess as few as three or up to 24 teeth per inch (TPI). A blade's TPI is one of its most significant characteristics, and greatly affects the way the saw is going to cut.

A lower TPI means faster, rougher cuts; larger TPIs are suited for slower, smooth cuts. Which one you want depends mostly on the material you'll be utilizing the blade on. When cutting metal, for example, you'll definitely require a blade that has a high TPI. There are also "variable-pitch" blades which possess more teeth in one section of the edge than another.
Some of the cutting blades require nominal upkeep. The reciprocating saw blades that are created for cutting large materials need to be lubricated with oil frequently. One thing to keep in mind is the fact that many of the reciprocating saws are much simpler when it comes to blade changes.  Specifically those saws designed with a keyless blade clamp, which enables you to replace the blade with less time and effort than the other types of saw. Consequently, this feature is one thing that needs to be seriously considered should you expect frequent blade changes. Reciprocating saw blades are the most important components of the saw, considering that the blades are what make the Recipro-Saw so adaptable and convenient.
