A flexible surgical tool system including a driver bone

Abstract

The invention relates to a flexible surgical tool system containing a driving bone, including a flexible surgical tool and a driving unit; the flexible surgical tool includes a flexible continuum structure composed of a distal structure, a proximal structure and a middle connecting body; the distal structure The body consists of the distal segment, which includes the distal septal disc, distal fixation disc, and structural bone; the proximal structure includes the proximal segment, which includes the proximal septal disc, proximal fixation disc, and structural bone. Structural bone; the central connector includes a channel fixing plate and a structural bone guiding channel; the drive unit includes a drive unit fixing plate, and multiple linear motion mechanisms are arranged between the drive unit fixing plate and the channel fixing plate near the proximal structure, and the linear motion The output end of the mechanism is firmly connected with the first driving bone, one end of the first driving bone is firmly connected with one end of the second driving bone through the adapter unit, and the other ends of the first driving bone and the second driving bone pass through the proximal The end spacer disc is firmly connected with the proximal fixed disc.

Description

technical field [0001] The invention relates to a flexible surgical tool system including a driving bone, 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 existing Intuitive Surgical company's da Vinci surgical robot assists doctors to complete multi-hole laparoscopic minimally invasive surgery, which 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 module and surgical operation arm, reach ...

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 surgical robot, which transforms the original rigid surgical instrument into a semi-rigid surgical instrument, and adds a pre-bent sleeve, which improves the movement performance of the surgical instrument to a certain extent, but Still unable to fundamentally solve the problems faced by traditional surgical instruments
