Medical robotic arm

Abstract

The invention relates to a medical mechanical arm. The medical mechanical arm comprises a mounting structure, a bracket structure, a driving structure and a control structure, wherein one end of the bracket structure is fixed at the mounting structure, a mounting site is arranged at the other end of the bracket structure and is used for mounting surgical instruments in a mounting cavity; the driving structure is arranged in the bracket structure and is in driving connection with the surgical instruments in the mounting cavity in the mounting site; and the control structure is connected to themounting structure, one end of the control structure faces towards the mounting site, and the control structure is used for connecting the surgical instruments in the mounting cavity through the driving structure and controlling the surgical instruments in the mounting cavity in the same direction. The medical mechanical arm is simple in design and light in structure, and the surgical operation can be realized by one hand of a user; the structure is simple, so that the collision is avoided; by utilizing a homodromous control manner, the problems that the reverse operation and control are required by a user in a traditional mode are avoided; and the medical mechanical arm is accordant with the operation habit of the user, so that the medical accidents caused by the misoperation can be reduced, and the surgical efficiency is improved.

Description

technical field [0001] The invention relates to the field of surgical devices, in particular to a medical mechanical arm. Background technique [0002] The Da Vinci Surgical System, commonly known as the Da Vinci Surgical Robot or the Da Vinci Robotic Surgical System, is an advanced robotic platform designed to perform complex surgical procedures using minimally invasive methods. The da Vinci robotic surgery system is based on robotic surgery technology developed at the Massachusetts Institute of Technology. Intuitive Surgical Company (hereinafter referred to as Intuitive) jointly developed the system with IBM, MIT and Heartport Company. The FDA has approved the da Vinci robotic surgical system for adult and pediatric general surgery, thoracic surgery, urology, obstetrics and gynecology, head and neck surgery, and cardiac surgery. The da Vinci Surgical System is an advanced robotic platform designed to perform complex surgical procedures using a minimally invasive approach...

AI Technical Summary

Problems solved by technology

In the hospital, the surgeons take turns to rest, but the robot cannot rest, and it is busy with operations even on holidays

In this case, it is necessary to replace multiple robotic arms every day, affecting the efficiency of surgery, and due to Intuitive’s monopoly setting of robotic arms, it leads to a lot of waste of materials

And, in order to save costs, some hospitals only use 3 robotic arms, which may lead to surgical risks

[0006] Therefore, the Da Vinci Surgical System has the following problems: the mechanical arm has a large structure, is expensive, and monopolistically sets the limit on the number of times of use, resulting in a serious waste of materials; and due to the large structure of the mechanical arm and problems in the position design, collisions may occur during use
