Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 As shown, the present invention includes a flexible continuum structure and a driving unit, and the flexible continuum structure includes a distal structure 11 (such as figure 2 shown), the proximal structure 16 (such as image 3 shown) and the middle connecting body 15. The distal structural body 11 includes a first distal structural section 12 and a second distal structural section 13 with a series connection relationship; the proximal structural body includes a proximal structural section, and the proximal structural section is connected to the second distal structural section through a middle connecting body 15. The distal joints 13 are associated, and when the proximal joints are bent in any direction, the second distal joints 13 are correspondingly bent in the opposite direction. The driving unit includes a proximal j...

The invention relates to a transurethral manual instrument. The transurethral manual instrument comprises a flexible continuous body structure and a driving unit. The flexible continuous body structure comprises a far-end structural body, a near-end structural body and a middle connector. The far-end structural body comprises a first far-end segment and a second far-end segment, the near-end structural body comprises a near-end segment, and second segment structural bones located on the near-end segment and second segment structural bones located on the second far-end segment are fastened and connected in a one-to-one correspondence mode or are the same structural bones. The middle connector comprises channel fixing plates, channel fixing blocks, first structural bone guide channels and second structural bone guide channels. The driving unit comprises a near-end segment driving handle and a first far-end segment driving assembly, and the near-end segment driving handle is connected with a near-end fixing disc in a fastened mode. The first far-end segment driving assembly is located between the two channel fixing plates, and the output end of the first far-end segment driving assembly is formed by two sliding blocks conducting reverse motion along the straight line. One ends of first segment structural bones are connected with the sliding blocks in a fastened mode, and the other ends of the first segment structural bones penetrate through the channel fixing blocks, the first structural bone guide channels and first far-end spacing discs and then are connected with first far-end fixing discs in a fastened mode.
Description
technical field [0001] The invention relates to a manual instrument that can pass through the urethra, belonging to the field of medical instruments. Background technique [0002] In the modern medical field, manual porous laparoscopic minimally invasive surgery has been widely used clinically. Such minimally invasive procedures have successfully reduced patients' postoperative pain, complications, recovery hospital stay, 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 that requires multiple body surface incisions, all surgical tools in single-port laparoscopic minimally invasive surgery enter the abdominal cavity through one body surface incision (usually the navel), which further reduces the trauma to the patient. However, the configuration of such a single inlet...
