Minimally invasive surgery mechanical arm used in LESS (laparo-endoscopic single site surgery) environment

Abstract

The invention relates to a minimally invasive surgery mechanical arm used in an LESS (laparo-endoscopic single site surgery) environment. The minimally invasive surgery mechanical arm comprises an operating unit and a drive unit, wherein the drive unit and the operating unit are connected through a drive thread group used for controlling the operating unit to move; the drive thread group comprisesa forceps clip joint drive thread, an upper arm drive thread, a lower arm drive thread and a hollow drive thread; the operating unit comprises a forceps clip mechanism and a hollow joint; the forcepsclip mechanism is connected with the hollow joint through two semi-circular meshing gears arranged at the top end of a hollow cylinder of the drive unit; the forceps clip mechanism comprises a lowerarm swing joint, an upper swing joint and a forceps clip joint which are connected from bottom to top in sequence; the forceps clip joint comprises left forceps and right forceps; each of the left forceps and the right forceps comprises a forceps clip and a forceps clip handle. The minimally invasive surgery mechanical arm is simple in structure, small in size, low in weight and low in cost.

Description

technical field [0001] The invention relates to the field of medical equipment for minimally invasive surgery, in particular to a minimally invasive surgical manipulator, in particular to a minimally invasive surgical manipulator used in a single-hole laparoscopic environment. Background technique [0002] Minimally invasive surgery is an important theme in the development of contemporary surgery. It is generally believed that the first laparoscopic cholecystectomy performed by French doctor Mouret in 1987 is a sign of minimally invasive surgery (MIS). The traditional porous endoscopic technology can complete the operation requiring an incision of more than ten centimeters in the case of traditional laparotomy only through several small-caliber poking cards, which not only significantly reduces the size of the incision, but also does not significantly increase the difficulty of the operation. The recovery process shortens the hospitalization time of patients, and the clinica...

Problems solved by technology

[0005] In order to solve the problems that the existing imported surgical robots mentioned in the background technology are too expensive, difficult to operate, and not suitable for widespread promotion, the present invention proposes a minimally invasive surgical robotic arm for single-port laparoscopic environments. The robotic arm is simple to operate, low in price, and easy to promote
