What Are the Different Types of Biopsy Needles?

Biopsy needles are of utmost importance in the diagnosis of certain diseases such as cancer and the likes. Doctors get samples of the tissues that need to be studied in order to get a better picture of what is really the general status of the organ or other parts of the body that needs evaluation. Before a doctor will perform surgery, he will need to acquire a sample specimen first and have it sent to the histopathology section of the hospital laboratory where it is processed and read by a pathologist to determine if the object of inspection has cancer or free from it.

In some cases, the surgeon may require a small chunk of the organ or part to be examined, while in other cases all that is needed are really small amounts of flesh or fluid as a sample. In this case, they are used to extract the sample directly from the organ or part to be tested.

The biopsy needle types largely depend on its purpose and also the organ involved in the biopsy. For example, percutaneous liver biopsies use aspiration or asuction type needles, for their oblique tip that has slightly convex tip as it extends outward. Another type of needles used are the cutting type needles also know as the automatic biopsy needles. They are spring loaded and once triggered, it slices in a rapid-firing side-notch manner cutting through parenchyma cells of the liver.

For lung biopsies, coaxial needles are used. They are characterized by its increased rigidity and torque, which can overcome any resistance from the surrounding soft tissues and can collect multiple samples from a single procedure. Additionally, single shaft needles can also be used, since they are more flexible and maneuverable than the previous needle. They also puncture through soft tissues easily provided that no heavy tissue resistance is present. Nonetheless, a cutting needle, due to the barbed edges that enable the needle to cut large tissue samples from the pulmonary nodule, also works well. A 14 to 21 gauge needle can be used and can also be incorporated in a biopsy gun.

There are also soft tissue needles and bone marrow needles. The soft tissue needle are specifically made to capture good quality soft tissue samples while minimizing trauma to the patient. While bone marrow needles are very rigid, which allow them to drill through bones to acquire bone marrow samples.

Performing biopsies takes a lot of practice and training in order to hit the right spot that the doctor is aiming. To assist the physicians in hitting the right spot the first time, they normally use needle guides These needle guides are incorporated into the needles itself. They are usually 0.55-0.9mm wide and are usually placed on the tip of the needle. This will enable the clinician to see the direction of the biopsy needles inside the body. Compared to puncturing the site blind and without any idea what you might hit, these needle guides make it easier for the clinician to be accurate and eliminate critical errors in operation.

Different Types of Breast Reconstruction

There are more than 200,000 cases of breast cancer each year in the United States alone. Most of these women have never thought they would have to remove either a portion or the entirety of the breast. This may seem overwhelming, but you should know that you do have options when you have a mastectomy. The breast can be reconstructed and the surgery won't be noticeable after the procedure is complete.

One type of breast reconstruction that you might consider is having breast implants put in immediately after a mastectomy. If you go with this option, the breast implant is lodged behind the chest's pectoral muscle. Your surgeon will probably use a permanent implant, which would depend on the breast skin quality following the mastectomy and how large the implant is going to be. Once you're on your way to full recovery, which might be after a month or two after the surgery, your doctor may suggest a secondary procedure to adjust the contour of your breast shape. This additional procedure is simply done to adjust breast symmetry and can be performed on an outpatient basis.

A second option when thinking about a breast reconstruction is to get a breast implant using a staged approach. This process can begin immediately following a mastectomy, or it can be delayed as to give yourself more time to analyze your options. In the staged approached, a tissue expanding device is placed along the chest wall under the pectoral muscle. This acts as a space saver in which the permanent implant will eventually be placed into. A small amount of saline is injected into the expander. After a few weeks of healing, the expansion process can start to begin where the doctor will inject more saline into the expanding device through a fill-port located in the device. This port is reached by using a needle through the skin. After several months of expansion, the female will then have an operation to exchange the expansion device for a permanent breast implant.

There is a third option in the TRAM flap procedure. With this procedure, tissue is removed from the abdomen and moved up to the chest in order to create new breast tissues. This will create a more natural feeling breast as you are using your own natural tissue, and you may even achieve better symmetry using this approach. There are a few disadvantages however, one of which is a scar that can run across your entire abdomen from hip to hip. You may also experience weaknesses in your abdominal wall, bulges or even a hernia.

No matter what breast reconstruction you choose in the end, you have to make sure you get a clear comparison among all three methods by speaking with a qualified physician so that you will be comfortable with your final decision on how to go about your breast cancer surgery.
