Abstract

The invention discloses an intraperitoneal traction surgical robot for minimally invasive surgery, relates to a robot for minimally invasive surgery and aims at solving the problems that an existing surgical instrument is liable to being interfered in a surgical process, meanwhile, the flexibility in movement and the freedom of the surgical instrument in the surgical process are relatively poor and the existing surgical robot has large volume and expensive price. The intraperitoneal traction surgical robot comprises a housing, a swing mechanism, a telescopic mechanism and a clamping mechanism, wherein the swing mechanism comprises a first motor, a first bevel gear, a second bevel gear and a shoulder rotating connecting rod; the telescopic mechanism comprises a second motor, a first cylindrical gear, a second cylindrical gear, a first screw pair and a sleeve; the clamping mechanism comprises a third motor, a second screw pair, a first connecting rod, a second connecting rod, a third connecting rod and pliers; and the swing mechanism, the telescopic mechanism and the clamping mechanism are arranged in the housing. The intraperitoneal traction surgical robot disclosed by the invention is used for minimally invasive surgery.

Description

technical field [0001] The invention relates to a robot for minimally invasive surgery. Background technique [0002] Laparoscopic surgery has many advantages, has developed rapidly, and has become a milestone in surgery. It has become the procedure of choice in cholecystectomy, appendectomy and other operations. However, laparoscopic surgery also has some disadvantages. The inherent flexibility of laparoscopic surgical instruments makes it difficult to operate, and the lack of visual and tactile feedback brings troubles to doctors. In addition, surgeons hope to further exploit the advantages of laparoscopic surgery by reducing the number of surgical incisions, thus giving birth to single-port laparoscopic surgery (LESS) and natural orifice laparoscopic surgery (NOTES). LESS can achieve the ideal effect of no obvious surgical scars on the body surface, which is of great significance to patients, but it is precisely because of the single hole that the operating space is lim...
