Mechanical arm for minimally invasive surgery robot

Abstract

The invention discloses a mechanical arm for a minimally invasive surgical robot. The mechanical arm comprises a plurality of operating arm sections and a connecting seat which are sequentially connected in series, the adjacent arm sections are connected through a rotary joint or a movable joint, the arm sections and the connecting seat are connected through a rotary joint or a movable joint, and the connecting seat is used for mounting surgical instruments such as an endoscope and surgical forceps. An operating arm I, an operating arm II and an operation arm III of the mechanical arm are adjusted to achieve rapid positioning of the position where a surgical instrument extends into a wound, a light beam emitting device is installed at the tail end of a linear section structure of the operating arm III, and a light beam coincides with the axis of a linear section and is used for guiding arrangement and positioning of the mechanical arm before a surgery; and on the basis, an operation arm IV, an operation arm V and an operation arm VI are adjusted, so that the arm rod of the surgical instrument can rotate around the wound position and finally extend into the wound at a proper angle.

Description

technical field [0001] The invention relates to the technical field of minimally invasive surgical robots, in particular to a mechanical arm for minimally invasive surgical robots. Background technique [0002] Minimally invasive surgery means that doctors use long and thin surgical tools to penetrate into the body through tiny incisions on the surface of the human body for surgical operations; compared with traditional open surgery, it has small surgical incisions, less bleeding, small postoperative scars, and faster recovery. The time is fast and other advantages, which greatly reduces the pain suffered by the patient. [0003] Minimally invasive surgery can bring many benefits to patients, but it adds a series of difficulties to the operation of doctors. Doctors must undergo long-term training before they can perform minimally invasive surgery. The surgical robot system can assist doctors and expand their capabilities. More flexibility, safety and reliability, helping to...

AI Technical Summary

Problems solved by technology

[0004] Minimally invasive surgical robots are high-tech intensive high-end precision medical equipment. There is no self-produced clinically applicable minimally invasive surgical robot system in the Chinese market. Existing foreign minimally invasive surgical robots have flexibility in overall structure layout , and there are still some deficiencies in the efficiency of preoperative planning and placement
