How much do you know about disposable laparoscopic trocars?
When it comes to laparoscopic surgery, people are not unfamiliar. Usually, the operation is performed in the patient cavity through 2-3 small incisions of 1 cm. The main purpose of the disposable laparoscopic trocar in laparoscopic surgery is to penetrate. The full-thickness abdominal wall establishes a channel between the outside world and the abdominal cavity, allowing surgical instruments to enter the abdominal cavity through the trocar sleeve, completing the surgical process and achieving the same purpose as traditional open surgery.
The disposable trocar for laparoscopy is composed of two parts: a puncture sleeve and a puncture core. The main task of the puncture core is to penetrate the abdominal wall with the trocar sleeve and leave the puncture sleeve on the abdominal wall. The main task of the puncture cannula is to allow various surgical instruments to enter the abdominal cavity, so that the doctor can perform surgical operations and complete the surgical task.
Two-sided separation of the head end of the puncture core
According to the statistical analysis of the report, many puncture complications are caused by infection, bleeding, puncture hernia and tissue damage.
Disposable trocar for laparoscopy has a transparent cone-shaped head, and uses a knife-free blunt dissection method to replace the cutting tissue with dividing tissue. When the trocar enters the abdominal wall, the puncture core pushes the tissue and blood vessels away along the tissue fibers, with a minimum of Limit damage to the abdominal wall and blood vessels, and reduce fascia damage by about 40% and the formation of puncture hernia by more than 80% compared with the trocar with a knife. Through the endoscope, the entire process of abdominal wall puncture can be directly controlled to avoid damage to the abdominal tissue , It can also save operation time and reduce operation pain.
02 Sheath outer barb thread
The outer barbed thread is used on the surface of the disposable trocar sheath to increase the fixation of the abdominal wall. When the puncture core is pulled out, the strength increases, which can improve the fixation of the abdominal wall by about 90%.
03 45° inclined surface opening at the head end of the sheath
The tip of the disposable trocar sheath for laparoscopic use is open at a 45° bevel, which facilitates the entry of the specimen into the sheath and leaves room for instrument manipulation.
04 complete model specifications
Disposable trocars for laparoscopic use have various specifications: inner diameter 5.5mm, 10.5mm, 12.5mm, etc.
All in all, the disposable trocar for laparoscopic minimally invasive surgery can reduce the patient's blood loss, make the patient recover faster, make the operation time shorter, and make the patient the beneficiary of minimally invasive abdominal surgery
