Polished Stainless Steel Laparoscopic Trocar With Cannula, for Surgery, Size : 3-10mm

Listing ID #6915434

A laparoscopic trocar is a medical instrument used during minimally invasive surgical procedures. It is designed to create access points in the abdominal wall for the insertion of other surgical instruments, such as laparoscopes and surgical tools, allowing the surgeon to perform the procedure without making large incisions.

The laparoscopic trocar consists of several components:

1. Cannula: The cannula is a hollow tube that serves as the primary access point for surgical instruments. It is inserted into the abdominal wall, providing a pathway for the insertion of other instruments. The cannula comes in various sizes and lengths to accommodate different surgical needs.
2. Trocar: The trocar is a sharp, pointed instrument that is used to puncture the abdominal wall and create an opening for the cannula. It is inserted into the cannula and advanced through the abdominal layers until it reaches the peritoneal cavity. Once the trocar reaches the desired depth, it is removed, leaving the cannula in place.
3. Obturator: The obturator is a rod-shaped component that is inserted into the cannula to protect the sharp tip during insertion. It is removed once the cannula is in place, allowing other instruments to be inserted through the cannula.
4. Valve system: Many laparoscopic trocars feature a valve system to maintain insufflation (inflation) of the abdomen during the procedure. The valves prevent the escape of carbon dioxide gas, which is used to inflate the abdominal cavity, providing a clear operating space for the surgeon.
5. Seal or seal cap: Some trocars also have a seal or seal cap that allows instruments to be inserted through the cannula while maintaining the pneumoperitoneum (abdominal insufflation). The seal or seal cap provides a tight seal around the instrument, preventing gas leakage.

Overall, laparoscopic trocars facilitate minimally invasive surgery by creating access points and maintaining a stable working environment within the abdomen. They enable surgeons to perform a wide range of laparoscopic procedures with smaller incisions, reduced postoperative pain, and faster recovery times compared to traditional open surgery.
