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 Si...

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like figure 1 As shown, the present invention includes a flexible continuum structure 10 and a drive unit 20 .

[0029] The flexible continuum structure 10 of the present invention includes a distal structure 101 (such as figure 2 shown), the proximal structure 102 and the middle connector 103, wherein the distal structure 101 is associated with the proximal structure 102 through the middle connector 103; the drive unit 20 is associated with the proximal structure 102, when the drive unit 20 When the proximal structural body 102 is driven to bend in any direction, the distal structural body 101 is correspondingly bent in the opposite direction. like figure 2As shown, the distal structure 101 includes two distal segments 104 , 105 , each distal segment 104 , 105 includes a distal spacer disc 106 , a distal fixation disc 107 and a structural...

Abstract

The invention relates to a flexible surgical operation tool system driven by a twin thread screw which comprises a flexible continuum structure and a drive unit; the flexible continuum structure includes a remote structural body, a local structural body and a middle connector; the remote structural body is provided with at least one remote joint, which comprises a remote space disk, a remote fixing plate and a structural bone; the local structural body is provided with as many local joints as the remote joints. The local joint comprises a local spacer disk, a local fixing plate and a structural bone; the middle connector comprises two channel fixing plates and a structural bone guiding channel located in between; the drive unit comprises a drive unit fixing board provided at the front end of the middle connector. A plurality of straight line motion assemblies are provided between the drive unit fixing plate and the channel fixing plate to convert the input of motor rotation into the output of straight motion of the straight motion mechanism. The output of the straight motion mechanism is linked to one side of the drive bone, which penetrates through the local space disk. The other side is fastened to the local fixing disk.

Description

technical field [0001] The invention relates to a flexible surgical tool system driven by a double-ended screw rod, 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...
