Embodiment 1

[0024] like figure 1 , figure 2 As shown, this embodiment includes a flexible continuum structure 10 and a drive handle 20 .

[0025] The flexible continuum structure 10 includes a distal structure 11 (eg image 3 shown), the proximal structure 16 (such as Figure 4 shown) and the middle connector 15. The distal structure 11 includes a first distal segment 12 and a second distal segment 13 in a serial connection relationship; the proximal structure 16 includes one proximal segment. The proximal segment is associated with the first distal segment 12 and the second distal segment 13 through the middle connecting body 15 , and when the proximal structure 16 is bent, the distal structure 11 can be driven to bend accordingly. A drive handle 20 is associated with the proximal structure 16 for controlling the bending of the proximal structure 16 .

[0026] The first distal segment 12 includes a first distal spacer disc 121, a first distal fixation disc 122 and a first segment s...

Embodiment 2

[0036] The difference between this embodiment and the first embodiment is that the first structural bone 163 (123) passes through the structural bone guiding channel 151, while the second structural bone 164 (133) crosses the guiding channel from the structural bone 153 through. The structures of other parts are the same as those of the first embodiment.

Abstract

The invention relates to a flexible surgical tool with oppositely-crossed 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 an intermediate connector; the far-end structural body comprises first far-end segments and second far-end segments, and the near-end structural body comprises a near-end segment; first segment structural bones on the near-end segment and first segment structural bones on the first far-end segments are in one-to-one corresponding fastened connection or form a whole; second segment structural bones on the near-end segment and second segment structural bones on the second far-end segments are in one-to-one corresponding fastened connection or form a whole; the intermediate connector comprises two channel fixing plates between which a structural bone guiding channel and a structural bone crossed guiding channel are in fastened connection; the first segment structural bones pass through the structural bone crossed guiding channel, and the second segment structural bones pass through the structural bone guiding channel.

Description

technical field [0001] The invention relates to a flexible surgical tool with opposed and cross-arranged structural bones, belonging 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. Such minimally invasive procedures have successfully reduced patients' postoperative pain, complications, hospital stay for recovery, and improved postoperative scar appearance. In order to further reduce surgical trauma and reduce patient pain, researchers proposed single-port laparoscopic minimally invasive surgery. [0003] Compared with multi-hole laparoscopic minimally invasive surgery, which requires multiple surface incisions, in single-port laparoscopic minimally invasive surgery, all surgical tools enter the abdominal cavity through a body surface incision (usually the navel), which further reduces the trauma to the patient. However, the co...
