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

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the present invention includes a flexible surgical tool 10 and a drive unit 20 .

[0034] Such as Figure 1~3 As shown, the flexible surgical tool 10 includes a flexible continuum structure composed of a distal structure 11 , a proximal structure 16 and a middle connecting body 15 .

[0035] The distal structure 11 includes a first distal joint 12 and a second distal joint 13, and the first distal joint 12 includes a first distal spacer disc 121, a first distal fixed disc 122 and a first joint Structural bone 123 ; the second distal joint 13 includes a second distal spacer disc 131 , a second distal fixation disc 132 and a second joint structural bone 133 . Among them, the first distal spacer disc 121 and the second distal spacer disc 131 are respectively distributed in the first distal segment 12 and the second di...

Abstract

The invention relates to a flexible surgical tool system adopting constrained structure bones. The flexible surgical tool system comprises flexible surgical tool which comprises a flexible continuum structure formed by a far-end structure, a near-end structure and a middle connector; the far-end structure comprises far-end structure sections, and each far-end structure section comprises a far-end distance plate, a far-end fixed plate and one structure bone; the near-end structure comprises near-end structure sections, and each near-end structure section comprises a near-end distance plate, a near-end fixed plate and one structure bone; the middle connector comprises passage fixed plates and a structure bone guiding passage; the near-end structure sections are internally provided with the constrained structure bones, one end of each constrained structure bone is firmly connected with the corresponding passage fixed plate closed to the corresponding near-end structure section, the other end of each constrained structure bone is directly or indirectly connected with the corresponding near-end fixed plate, and the length of each near-end structure section remains unchanged when the near-end structure section turns.

Description

technical field [0001] The invention relates to a flexible surgical tool system using constrained structural bones, 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 a...
