A flexible surgical tool system employing a sterile barrier

Abstract

The invention relates to a flexible surgical tool system adopting a sterile barrier. The flexible surgical tool system comprises a flexible surgical tool and a driving unit, wherein the flexible surgical tool comprises a far-end structure, a near-end structure and a middle connector; the far-end structure comprises a far-end component; the far-end component comprises a far-end interval plate, a far-end fixed plate and a structure bone; the near-end structure comprises a near-end component; the near-end component comprises a near-end interval plate, a near-end fixed plate and a structure bone; the middle connector comprises a channel fixing plate and a structure bone guiding channel; the driving unit comprises a motor part, a motion conversion part and a linear motion mechanism; the motor part comprises a first fixing plate and a first motor; the motion conversion part comprises a driving chain; the rotating output of the first motor is converted into the linear motion of an output rod by the driving chain and is transmitted to a push-pull rod of the linear motion mechanism through the sterile barrier; an output end of the linear motion mechanism is connected with one end of the driving bone.

Description

technical field [0001] The invention relates to a flexible surgical tool system using a sterile barrier, 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 t...

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
