A multipurpose flexible surgical tool system

Abstract

The invention relates to a multipurpose flexible surgical tool system, which includes a flexible surgical tool, a sterile barrier, a motor unit and a linear module; the flexible surgical tool includes a flexible continuum structure and a transmission drive unit; the flexible continuum structure includes a remote An end structure body, a proximal structure body and a connecting body; the distal structure body includes a first distal-end structural section and a second distal-end structural section; a transmission drive unit is associated with the first distal-end structural section to drive the first distal-end structural section The second distal segment is associated with the proximal structure through the connecting body, and the transmission drive unit is also associated with the proximal structure to drive the proximal structure to perform bending motion, thereby indirectly driving the second distal The end structure section performs bending motion; the motor unit is connected to the flexible surgical tool through a sterile barrier to provide driving force for the transmission drive unit; the output end of the linear module is connected to the motor unit to drive the flexible surgical tool to achieve linear progress. Give movement.

Description

technical field [0001] The invention relates to a multipurpose flexible surgical tool system, which belongs to the field of medical instruments. Background technique [0002] Porous laparoscopic minimally invasive surgery has occupied an important position in surgical operations because of its small incision and fast postoperative recovery. The da Vinci (Da Vinci) surgical robot of the existing Intuitive Surgical Company (American Intuitive Surgical Company) assists doctors in completing multi-hole laparoscopic minimally invasive surgery, and has achieved great commercial success. [0003] After multi-port laparoscopic surgery, minimally invasive surgery has developed single-port laparoscopic surgery and non-invasive surgery through natural orifice, which are less invasive to patients and have higher postoperative output. However, in single-port laparoscopic surgery and non-invasive surgery through the natural orifice, all surgical instruments, including the visual lighting...

AI Technical Summary

Problems solved by technology

Since the wire rope must be kept in a continuous tension state through the pulley, this driving method is difficult to achieve further miniaturization of surgical instruments, and it is also difficult to further improve the movement performance of the instruments

[0004] Although Intuitive Surgical recently launched the da Vinci Single-Site (SS Da Vinci) surgical robot, which transforms the original rigid surgical instrument into a semi-rigid surgical instrument and adds a pre-bent sleeve, which improves the surgical robot to a certain extent. The kinematic performance of surgical instruments, but still cannot fundamentally solve the problems faced by traditional surgical instruments
