Abstract

The invention discloses an instrument for a robot-assisted micro-invasive surgery. The instrument comprises a driving device, a connecting guide pipe and a terminal executing device which are sequentially connected; the driving device comprises a base, three driving shafts are rotationally arranged on the base through a bearing, and each driving shaft is fixedly sleeved with a screw roller and a cohesion block; the terminal executing device comprises a clamp seat and an opening and closing clamp, wherein the clamp seat is fixed at the front end of the connecting guide pipe, the opening and closing clamp consists of a left opening and closing clamp body and a right opening and closing clamp body, and the wire rollers connected with the left opening and closing clamp body and the right opening and closing clamp body and the left opening and closing clamp body and the right opening and closing clamp body are arranged on a hinge pin of the clamp seat; the connecting guide pipe, the left opening and closing clamp body and the right opening and closing clamp body are respectively connected with a screw driving system. The instrument provided by the invention is compact in structure, light in weight and high in driving precision, and the quick-changing efficiency of the instrument can be improved.

Description

technical field [0001] The invention relates to a minimally invasive surgical tool, in particular to a surgical tool for a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery represented by laparoscopy is known as one of the important contributions of medical science to human civilization in the 20th century, and is the main theme of global surgical development in the 21st century. Compared with traditional open surgery, minimally invasive surgery has the advantages of small incision, less bleeding, small postoperative scar, and quick recovery time, which greatly reduces the suffering of patients and is widely used in clinical operations. In recent years, robot-assisted minimally invasive surgery has emerged and developed rapidly. It overcomes many shortcomings of traditional minimally invasive techniques, and has the advantages of high operational flexibility, good stability, intuitive motion control, stereo vision and remote surgery....
