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

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as figure 1 As shown, the present invention includes a flexible surgical tool 10 and a drive unit 20 . The flexible surgical tool 10 includes a distal structure 101 (such as figure 2 shown), the proximal structure 102 (such as image 3 shown) and the middle connecting body 103 (such as Figure 5 Shown) is a flexible continuum structure. Among them, the distal structure 101 is associated with the proximal structure 102 through the middle connecting body 103; the drive unit 20 is associated with the proximal structure 102, and when the drive unit 20 drives the proximal structure 102 to bend in any direction, the distal The structure body 101 is correspondingly bent in the opposite direction.

[0039] Such as figure 2 As shown, the distal structure 101 includes a first distal segment 104 and a second distal segment 105 . The first di...

Abstract

The invention relates to a flexible surgery tool system with the far end capable of turning in any direction. The flexible surgery tool system comprises a flexible surgery tool and a driving unit. The flexible surgery tool comprises a far-end structural body, a near-end structural body and a middle connecting body. The far-end structural body comprises far-end segments, and each far-end segment comprises far-end spacing discs, a far-end fixing disc and structural bones. The near-end structural body comprises near-end segments, and each near-end segment comprises near-end spacing discs, a near-end fixing disc and structural bones. The middle connecting body comprises channel fixing plates and structural bone guide channels. The driving unit comprises a motor part, a motion conversion part and linear motion mechanisms. The motor part comprises a first fixing plate and first motors, the motion conversion part comprises transmission chains used for converting rotary output of the first motors into linear motion of output rods, the linear motion is transmitted to the input ends of the linear motion mechanisms through a sterile barrier, the output ends of the linear motion mechanisms are connected with one ends of driving bones, the driving bones penetrate through the near-end spacing discs, and the other ends of the driving bones are connected with the near-end fixing discs.

Description

technical field [0001] The invention relates to a flexible surgical tool system whose distal end can be bent in any direction, belonging 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 oper...
