Modular flexible surgical tool system

Abstract

The invention relates to a modular flexible surgical tool system which is characterized by comprising a flexible continuous body structure, a surgery execution unit and a driving unit, wherein the flexible continuous body structure comprises a far-end structural body, a middle connecting body and a near-end structural body which are sequentially associated; the driving unit is associated with the near-end structural body; a surgery executer in the surgery execution unit is associated with the far-end structural body; when a structure framework driving mechanism in the driving unit drives the near-end structural body to turn toward any direction, the far-end structural body correspondingly turns toward a reverse direction; a surgery executor driving mechanism in the driving unit can drive the surgery executor at the tail end of the far-end structural body, so that motion control on the surgery executor is realized. By virtue of a single surgical incision, the modular flexible surgical tool system can be well applied to a single-pore endoscopic surgery robot system and also can be applied to a porous endoscopic surgery robot system.

Description

technical field [0001] The invention relates to a medical device, in particular to a modularized flexible surgical tool system with front drive input. 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 li...

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
