For generations, surgeons have been using trocars to perform surgery and to reduce the trauma that is involved in operative procedures, to reduce the need for anesthesia, and to accelerate the patients' recovery process following surgery. Trocars are considered to be extremely useful surgical instruments.

Trocars and cannulas: what are they used for?

Trocars and cannulas make the administration of hormone therapy simple and predictable when treating endocrine disorders.
There are several forms of estrogen and testosterone replacement therapy that may benefit women. Some of these include pills, vaginal inserts, topical creams, lozenges, and hormone patches. Pellets, on the other hand, slowly release estrogen and testosterone into the circulatory system for up to six months. 
Since the pellets release the hormone slowly, the levels of the hormone in the bloodstream remain constant throughout the day like they would with oral or injectable hormones. As a result, women experience a lower risk of side effects from injections. 
As a general rule, men who benefit from testosterone therapy are typically injected with 10 or 12 pellets of the hormone once every four months in order to establish a baseline testosterone level, which can then be adjusted with patches or injections under the supervision of their doctor. 
Additionally, trocars can be used to deliver long-acting hormones that are needed for gender transition. They are even used to treat pets with hormone therapy. It is common for dogs and cats suffering from muscle atrophy, intervertebral disc disease, degenerative arthritis, hip dysplasia, and many other conditions to benefit from hormone therapy inserted through a trocar and cannula. 

What is the difference between a trocar and a cannula?

The term trocar came from the French from trois or three and carre sides, or faces. Trocars used to have three blades around a cannula, from the same Latin word meaning little hollow red. In order to remove fluids, the surgeon made an incision in the skin and subcutaneous tissue using the trocar, and then inserted the cannula. An obturator, a third part, keeps the cannula rigid enough for precise placement. Barter refers to the entire assembly.
The trocars of the twenty-first century may have blades, or they may not have blades at all. They may dilate, making a wider incision once they pass through the skin, so that the skin is pushed apart, not cut. The camera and surgical instruments can be passed through a very small opening in order for the surgeon to pass them through. 
There are several reasons why modern trocars are designed to be used with the smallest incision possible, allowing the cannula to stay in place during the procedure while minimizing trauma to the skin. Once the tractor has been removed, it is not necessary to stitch the fascia holding the tissues beneath the skin together if the diameter of the cannula is less than 5 millimeters. This means that the already low risk of hernias is even lower, the patient gets out of the treatment room faster, and there is usually no need for a general anesthetic. It only takes an injection of a local anesthetic to achieve this.
As a leading provider of trocar products for the placement of hormone pellets into people, Kangji Medical is a specialist in trocar products that prevent trauma to the skin, lower the risk of infection, and leave patients feeling more comfortable after the procedure.
Stainless steel disposable trocars are just 3.5 millimeters wide, and are perfect for shallow or deep insertion. Kangji Medical is able to provide your doctor with disposable medical trays kits and trocar wrap kits, both of which are autoclaved for sterilization between use, as well as reusable stainless steel bevel tips 3.5 millimeters in diameter.

Trocars and cannulas FAQ

When I get hormone pellets, will I need stitches?
 If your doctor uses a trocar of 3.5mm,the wound will seal on its own. To ensure that your incision heals properly, you may be asked to avoid strenuous activities (especially any exercise that puts pressure on your gluteus) for at least 48 hours. The surgical gauze can be removed the day after the procedure and you can take a shower afterward. However, the surgical tape needs to stay in place for five days. A week should be allowed for you to avoid exposure to potentially contaminated water, such as swimming pools, hot tubs, and lakes.
Is there a camera inside the trocar and cannula my doctor uses to place hormone pellets?
No, hormone pellets are placed close enough to the surface of the skin that a camera is not necessary.
Is it safe to use a reusable trocar and cannula?
By autoclaving, microscopic organisms are exposed to an extremely hot environment and are killed. Trocar Supplies manufactures its trocar and cannula kits from stainless steel so that they are unaffected by rust because they are made from stainless steel. This process also alters the metallic surface of the trocar so that even molecular-sized contaminants cannot adhere to it.
