Flexible surgery tool system containing driving bone

Abstract

The invention relates to a flexible surgery tool system containing a driving bone, and the system comprises a flexible surgery tool and a driving unit; the flexible surgery tool comprises a flexible continuum structure composed of a far-end structural body, a near-end structural body and a middle connector; the near-end structural body comprises a near-end structural joint, the near-end structural joint comprises a near-end distance plate, a near-end fixture plate and a structural bone; the middle connector comprises a channel fixing plate and a guiding channel for structural bone; the driving unit comprises a driving unit fixing plate, many straight line mechanisms are arranged between the driving unit fixing plate and the channel fixing plate near the near-end structural body, an output end of the straight line mechanism is fixedly connected to a first driving bone, one end of the first driving bone is fixedly connected to one end of a second driving bone, both of the other ends of the first driving bone and the second driving bone are fixedly connected to the near-end fixing plate after penetrating the near-end distance plate.

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
