Novel retractable minimally invasive surgery operation arm

Abstract

The invention provides a novel retractable minimally invasive surgery operation arm. The novel retractable minimally invasive surgery operation arm comprises an angle deflection mechanism, an offset error compensation mechanism, a drive mechanism, a joint mechanism and an electrotome mechanism. The novel retractable minimally invasive surgery operation arm has the advantages that the angle deflection mechanism is fixed on a minimally invasive surgery mechanical arm mounting table, so that the stability of the whole mechanism is guaranteed; the offset error compensation mechanism can control the extension length of a piston in a single-rod double-action air cylinder to appropriately adjust the distance and increase operation precision when an electrotome cannot reach an appointed surgery part through the drive mechanism and the joint mechanism or exceeds a lesion part; the drive mechanism uses for motors of the same type to perform driving and uses a lever structure to adjust joint angle; the joint mechanism uses a joint serial connection type structure and controls the joint angle by adjusting the tightness of an internal steel wire rope; the electrotome mechanism is connected withthe joint mechanism, and the electrotome angle is adjusted through the steel wire rope.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel retractable operating arm for minimally invasive surgery. Background technique [0002] Modern minimally invasive surgery is a historic reform in the medical field. Compared with traditional surgery, minimally invasive surgery has the advantages of less bleeding, smaller wounds, fewer postoperative complications, and faster recovery. Based on these advantages , minimally invasive surgery is becoming more and more popular. With the rapid development of science and technology, robot technology has been continuously applied to minimally invasive surgery. The intervention of surgical robots has improved the success rate of minimally invasive surgery. The doctor controls the robot to complete various surgical actions, which greatly improves the surgical accuracy and avoids irreparable mistakes caused by factors such as human shaking. The robot has many Therefore, in ...

Problems solved by technology

[0003] Previous minimally invasive surgical robot manipulators have superimposed, passive, etc., but due to the complex internal environment of the human body, minimally invasive surgical robots must have enough flexibility to avoid important tissues and organs in the patient's body

[0004] At present, minimally invasive surgical robots have been commercialized in western countries, but domestic hospitals with minimally invasive surgical medical equipment still cannot meet people's needs for minimally invasive surgery
