  • This is the mechanism that enables the cannula to make the initial penetration into the abdomen.
trocar seal cap
  • The seal.
  •  This is found at the top of the cannula and ensures that no air escapes from the abdominal cavity while allowing any necessary equipment to be passed through. If air pressure is not properly maintained during laparoscopy, this can impede the surgeon’s view of the area being operated on.

  • The cannula.
  • This is the shaft that is inserted into the patient to estalish access for opertion instrument to the abdominal cavity.

Laparoscopic technology and methods are continually improving and evolving, with modern innovations making this technique even more popular.

The Benefits of Laparoscopic Surgery
Currently laparoscopic surgery is a common surgical approach, through small incisions combined with specially adapted instruments to examine the organs located in the abdomen. Diagnostic laparoscopy minimizes scarring and distress to the patient. Recovery from laparoscopic surgery tends to be faster and there is less pain than with traditional surgical methods, and many procedures such as hernia repairs, gastric bypass, and organ removal, are all typically carried out laparoscopically. As well as offering many benefits to the patient, laparoscopy is also useful for doctors, who are able to see directly inside the body in real time without the need to perform open surgery. In addition, they can collect biopsy samples using this method when needed.

A patient may be advised to have a laparoscopy to examine:

The appendix
The gallbladder
The liver
The pancreas
The small and/or large bowel
The spleen
The stomach
The pelvic area
The reproductive organs
Diagnostic laparoscopy will allow the doctor to look for any unusual masses or tumors; fluid build-up in the abdominal cavity; liver disease; and how far a cancer has progressed. In addition, it can also demonstrate how effective a particular treatment has been.through
