Single port laparoscopic surgery system with front-loaded drive

Abstract

The invention relates to a single port laparoscopic surgery system with a front-loaded drive. The system comprises a flexible operation tool, an imaging tool, a catheter body and a drive body, wherein the flexible operation tool comprises a first flexible arm body, an operation execution device and a first drive transmission unit; the imaging tool comprises a second flexible arm body, an imaging illumination module and a second drive transmission unit; the catheter body comprises a catheter and a multi-chamber pipe body; the drive body comprises a skeleton correlated with the catheter body as well as multiple drive modules which are firmly connected to the skeleton and correlated to the first and second drive transmission units respectively; an overall feeding freedom degree, an overall rotation freedom degree and a turning freedom degree of the first flexible arm body are achieved by the drive modules through the correlated first drive transmission unit; and an overall feeding freedom degree and a turning freedom degree of the second flexible arm body are achieved by the drive modules through the correlated second drive transmission unit. According to the invention, multiple flexible operation tools and imaging tools can be inserted into a human body via the same multi-chamber pipe body for an operation.

Description

technical field [0001] The invention relates to a medical device, in particular to a front-drive single-hole laparoscopic operation system. Background technique [0002] In the modern medical field, manual porous laparoscopic minimally invasive surgery has been widely used clinically. Such minimally invasive procedures have successfully reduced patients' postoperative pain, complication rates, recovery time, and improved postoperative scarring. In recent years, in order to facilitate doctors' operation and achieve better postoperative output, robot-assisted porous laparoscopic minimally invasive surgery has been widely used. The robotic system, which can assist doctors in performing multi-hole laparoscopic minimally invasive surgery, has achieved great commercial success. [0003] In order to further reduce the surgical trauma area and recovery time, researchers proposed single-port laparoscopic minimally invasive surgery. Compared with multi-hole laparoscopic minimally i...

AI Technical Summary

Problems solved by technology

Manual single-port laparoscopic surgery based on traditional rigid surgical tools has not yet been used in clinical practice due to the complex hand-eye coordination requirements, limited flexibility of surgical tools, and small working range.

[0004] The porous laparoscopic surgical robot, because the distal end of its surgical arm is mainly a series hinged structure of multiple rods, is driven by a wire rope to bend at each hinge joint, and the wire rope must be kept in a continuous tension state with the miniature pulley, so that Porous laparoscopic robots cannot be retrofitted into single-hole laparoscopic robots that work well in terms of miniaturization, kinematic performance, and safety
