Description

Viscera traction device for laparoscopic surgery

Technical Field

The invention relates to the technical field of medical instruments for operations, in particular to an organ traction device for laparoscopic operations.

Background

Laparoscopic surgery conventionally adopts a five-hole method for abdominal entry, which is respectively 2 main operation holes (main surgeons), 2 auxiliary operation holes (assistant surgeons) and 1 observation hole (laparoscopist). Compared with open surgery, laparoscopic surgery causes less trauma to patients and enables patients to recover quickly after surgery, and has become the mainstream mode of intraperitoneal surgery. The laparoscopic surgery requires that a trepan needle (trocar) with different calibers (generally, more than 5mm in diameter) is used for punching, and then main operation surgical instruments, auxiliary operation surgical instruments, a laparoscopic camera and the like are put into an abdominal cavity through the trepan needle sleeve to perform the surgery. The more laparoscopic surgery is perforated, the more pain the patient is subjected to, and more scars remain.

Therefore, the laparoscopic surgery with reduced port becomes a new development direction of laparoscopic technique under the 'minimally invasive concept', namely 2 doctors carry out surgery, "three-port method" enters abdomen, 2 main operation ports (main surgeons) and 1 observation port (endoscope supporting doctors). The laparoscopic surgery for reducing the puncture saves the labor cost (1 doctor is reduced to participate in the surgery) and can achieve the effects of postoperative beauty treatment and quick recovery (2 auxiliary operation holes are reduced) by reducing the pore channels for instruments to enter the abdominal cavity through the abdominal wall. The auxiliary operation hole of the traditional five-hole method is mainly operated by an assistant physician, aims to pull the visceral organs and the mesentery of a patient, assists in exposing the operative field, is convenient for a main physician to perform an operation, the traditional visceral organs and the mesentery pulling device need an independent auxiliary operation hole, and the abdominal entry of the traditional three-hole method is difficult to realize.

Therefore, how to design a low-trauma and repeatedly adjustable visceral organ traction device which can flexibly expose the operative field without an auxiliary operation hole is an urgent technical problem to be solved.
