Multi-purpose flexible surgical tool system

Abstract

The invention relates to a multi-purpose flexible surgical tool system. The system comprises a flexible surgical tool, a sterile barrier, a motor group unit and a linear module; the flexible surgicaltool includes a flexible continuum structure and a transmission drive unit; the flexible continuum structure includes a far-end structure body, a near-end structure body and a connector; the far-end structure body includes a first far-end structure joint and a second far-end structure joint; the transmission drive unit is associated with the first far-end structure joint to drive the first far-endstructure joint to conduct turning motions; the second far-end structure joint is associated with the near-end structure body through the connector, and the transmission drive unit is also associatedwith the near-end structure body to drive the hear-end structure body to conduct turning motions, thereby indirectly driving the second far-end structure joint to conduct the turning motion; the motor group unit is connected with the flexible surgical tool through the sterile barrier to provide driving force for the transmission drive unit; the output end of the linear module is connected with the motor group unit to drive the flexible surgical tool to achieve linear feed motions.

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
