What is a trocar?
Speaking of laparoscopic surgery, people are not unfamiliar. Usually, 2-3 small incisions of 1 cm are used to perform surgical operations in the patient’s cavity. The main purpose of disposable laparoscopic trocars in laparoscopic surgery is to penetrate the full thickness of the abdominal wall, establish a passage between the outside world and the abdominal cavity, and allow surgical instruments to enter the abdominal cavity through the trocar sleeve to complete the surgical process and achieve traditional open surgery Same purpose.
The disposable laparoscopic trocar consists of a puncture sleeve and a puncture core. The main task of the puncture core is to penetrate the abdominal wall along with the trocar sleeve, leaving the puncture sleeve on the abdominal wall. The main task of the puncture cannula is to allow various surgical instruments to pass into the abdominal cavity, so that the doctor can perform surgical operations and complete the surgical tasks.
Features and advantages of disposable trocars for laparoscopy
1.The tip end of the trocar core is separated on both sides
The core head of the disposable laparoscopic trocar is transparent and tapered. The blunt separation method without a knife is used. The tissue is separated instead of cutting the tissue. When the trocar enters the abdominal wall, the puncture core pushes the tissue and blood vessels away along the tissue fibers. Limit damage to the abdominal wall and blood vessels. Compared with the trocar with a knife, it reduces fascia damage by about 40% and reduces the formation of puncture hole hernia by more than 80%. Through the endoscope, the entire process of abdominal wall puncture can be controlled directly to avoid damage to the abdominal tissue It can also save operation time and reduce surgical pain.
2.Outer barbed thread of sheath
The surface of the disposable laparoscopic trocar sheath adopts an external barbed thread to increase the fixation of the abdominal wall. When the puncture core is pulled out, the strength is increased, which can improve the fixation of the abdominal wall by about 90%.
3.45° beveled opening at the tip of the sheath
The tip end of the sheath tube of the disposable laparoscopic trocar is inclined at a 45° angle, which facilitates the entry of the specimen into the sheath and leaves room for the operation of the instrument.
4.Complete model specifications
There are many specifications of disposable disposable laparoscopy trocars: inner diameter 5mm, 10mm, 12mm, etc.
