Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, this embodiment includes a flexible continuum structure 10 and a driving handle 20.

[0027] The flexible continuum structure 10 includes a distal structure 11 (such as image 3 Shown), the proximal structure 16 (such as Figure 4 Shown) and the central connecting body 15. The distal structure 11 includes a first distal structure 12 and a second distal structure 13 connected in series; the proximal structure 16 includes a proximal structure. The proximal knuckle is associated with the first distal knuckle 12 and the second distal knuckle 13 through the middle connecting body 15, and when the proximal structure 16 turns, the distal structure 11 can be driven to turn accordingly. The driving handle 20 is associated with the proximal structure 16 and is used to control the turning of the proximal structure 16.

[0028] The first distal knuckle 12 includes a first distal spacer disc 121, a first distal fixation disc 122, and a first struct...

Embodiment 2

[0038] The difference between this embodiment and the first embodiment is that: the first joint structure bone 163 (123) passes through the structural bone guide channel 151, while the second joint structure bone 164 (133) passes through the structural bone cross guide channel 153 through. The structure of other parts is the same as the first embodiment.

Abstract

The invention relates to a flexible surgical tool with cross arrangement of structural bones. The flexible surgical tool comprises a flexible continuum structure, wherein the flexible continuum structure comprises a far-end structural body, a near-end structural body and a middle connecting body; the far-end structural body comprises first far-end structural sections and second far-end structural sections; the near-end structural body comprises near-end structural sections; first structural section structural bones positioned on the near-end structural sections are in one-to-one correspondence to and are fastened connection with the first structural section structural bones positioned on the first far-end structural sections or form the same structural bone with the first structural section structural bones positioned on the first far-end structural sections; the second structural section structural bones positioned on the near-end structural sections are in one-to-one correspondence to and are fastened connection with the second structural section structural bones positioned on the second far-end structural sections or form the same structural bone with the second structural section structural bones positioned on the second far-end structural sections; the middle connecting body comprises two channel fixing plates; a structural bone guiding channel and a structural bone cross guiding channel are in fastened connection between the two channel fixing plates; the first structural section structural bones penetrate through the cross guiding channel; the second structural section structural bones penetrate through the structural bone guiding channel.

Description

Technical field [0001] The invention relates to a flexible surgical tool with a cross-arrangement of structural bones, and belongs to the field of medical instruments. Background technique [0002] In the modern medical field, manual multi-hole laparoscopic minimally invasive surgery has been widely used in clinical practice. This type of minimally invasive surgery has successfully reduced the patient's postoperative pain, complications, rehabilitation and hospitalization time, and improved the appearance of postoperative scars. In order to further reduce the surgical trauma and reduce the patient's pain, the researchers proposed single port laparoscopic minimally invasive surgery. [0003] Compared with multi-port laparoscopic minimally invasive surgery that requires multiple body surface incisions, all surgical tools in single-port laparoscopic minimally invasive surgery enter the abdominal cavity through a body surface incision (usually the navel), which further reduces the tra...
