Pipeline closer

Abstract

The invention discloses a pipeline closer, which belongs to the technical field of medical instruments, and comprises a mandrel, wherein a clamping head is arranged at the near end of the mandrel; a propelling device which comprises a connecting pipe, and internal threads matching external threads of the mandrel are arranged on the inner wall of the connecting pipe; a first partition plate perpendicular to the connecting pipe and arranged in the middle of the connecting pipe; a plurality of first radial clapboards uniformly arranged along the circumferential direction of the first clapboards; needle base assemblies arranged between the adjacent first radial partition plates, wherein needle cylinders of the needle base assemblies are rotationally arranged between the adjacent first radial partition plates, a sleeve arranged outside the propelling device in a sleeving manner; an upper cover comprising a curved surface section with the diameter gradually reduced from the outer circumference to the far end side of the mandrel, wherein a containing cavity used for being connected with a clamping head of the mandrel in a clamped mode is formed in the middle of the curved surface section, and a limiting device used for limiting the axial moving distance of the upper cover along the sleeve is arranged between the upper cover and the sleeve. Suture needles can be uniformly discharged at the same angle and intervals, uniform suture of the anastomosis end is facilitated, and liquid leakage of the anastomosis end is prevented.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a pipeline closure. Background technique [0002] Although various types of intestinal vascular anastomosis devices are common in clinical practice, there is still no end-to-end anastomosis device for urethral anastomosis in radical prostatectomy and cervical cancer surgery with cervix preservation. Radical prostatectomy urethral anastomosis and cervix-preserving cervical cancer surgery have high requirements on the uniformity of the suture angle and the tension of the anastomotic end. In the current anastomosis device, it is difficult to achieve uniform suture at the anastomotic end by the needle-out method in the current anastomotic device, which leads to leakage at the anastomotic end. liquid, affecting the surgical effect. Contents of the invention [0003] The present invention is proposed to solve the problems existing in the prior art, and its purpose is to ...
