Gastrointestinal surgery auxiliary robot system

Abstract

The invention provides a gastrointestinal surgery auxiliary robot system. The system is provided with a mobile base unit and a lifting unit fixed to the mobile base unit; the lifting unit is providedwith a flexible surgical instrument unit, one end of the flexible surgical instrument unit penetrates through an auxiliary passage to extend to a surgical field, a control handle is operated to control multi-degree-of-freedom movement of the flexible surgical instrument unit, and a flexible surgical instrument driving unit is controlled to drive feed movement of the flexible surgical instrument unit. Accordingly, on the basis that a traditional gastrointestinal endoscopy structure is not changed, by means of external auxiliary instrument cavity, a multi-degree-of-freedom mechanical arm is sentto the target surgical field through the external cavity, and the lifting and cutting functions of a target mucosa are achieved together by cooperating with a traditional endoscope and electrotome; for the common tools such as the electrotome and a needle, a clamping device is used for fixing the tools, the extension lengths of the electrotome head and the needle head can be adjusted freely, andthe use efficiency is improved while the research and development and maintenance cost is lowered.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an auxiliary robot system for digestive tract surgery. Background technique [0002] Traditional endoscopic mucosal dissection (ESD surgery) is performed by a gastroenterologist with the help of a digestive endoscope to complete the dissection of the lesioned mucosa. At present, most of the endoscopes used in the market are endoscopes with a single instrument channel, which can only meet the cutting of the lesioned mucosa, and cannot realize the lifting action when cutting it. Therefore, the doctor's personal skills and Experience is very demanding, which increases the risk of surgical complications and prolongs the operation time. Although there are digestive endoscopes with dual instrument channels on the market, the coaxiality of the two channels makes lifting and cutting inconvenient, which also leads to increased surgical complications. [0003] In order to me...

AI Technical Summary

Problems solved by technology

However, most of these studies have changed the structure of the endoscope itself, increasing the cost of research and development of the entire system and the cost of later promotion

[0004] Whether it is the traditional EDS surgical instrument or the treatment system with dual robotic arms, it does not solve the problem of placing the electric knife and injection needle during the operation, and the nurse still needs to hold it all the time, which is not only boring but also increases the labor intensity of the nurse.
