Flexible operation tool system capable of achieving disinfection

Abstract

The invention relates to a flexible operation tool system capable of achieving disinfection. The system comprises a flexible continuous body structure which comprises a far-end structure body, middle connectors and a near-end structure body; the far-end structure body comprises at least one far-end structure section which comprises a far-end spacing disk, a far-end fixing disk and structure bones; the near-end structure body comprises near-end structure sections with the same number as the far-end structure sections, and each near-end structure section comprises a near-end spacing disk, a near-end fixing disk and structure bones; the near-end structure sections are connected with the far-end structure sections in parallel through the middle connectors; the system further comprises a transmission unit which comprises a transmission mechanism fixing plate arranged in front of the middle connectors, a gear transmission mechanism used for converting rotational motion input into linear motion output is arranged on the transmission mechanism fixing plate, the output end of the gear transmission mechanism is connected with one end of a driving bone in a fastened mode through an adapter, and the other end of the driving bone penetrates through the near-end fixing disks and then is connected with the near-end fixing disks in a fastened mode.

Description

technical field [0001] The invention relates to a sterilizable 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 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 the surgical...

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 microsurgical instruments
