Problems solved by technology

And the reliability of anastomosis is far less than that of open surgery. The existing gastrointestinal stapler and vascular stapler cannot be used to anastomose the ureter due to size and structure problems, resulting in greater difficulty in anastomosis of the ureter and longer operation time

Embodiment Construction

[0017] As shown in the figure: surgical separation forceps that can be used for ureteral anastomosis, including shell 1, fixed handle 2, movable handle 3, nail pressing handle 4, nail abutment seat 5, nail magazine 6, nail pressing plate 7, separation pull rod 8, pressing Nail pull bar 11 and telescopic link mechanism 9.

[0018] The housing 1 includes two parts, the probe rod housing 101 and the handle housing 102. Both the probe rod housing 101 and the handle housing 102 have a cavity, and the cavities of the probe rod housing 101 and the handle housing 102 are connected to each other. Communication, the fixed handle 2 is integrally connected with the handle housing 102, the movable handle 3 and the nailing handle 4 are hinged on the handle housing 102 through a pin shaft, and the movable handle 3 is arranged on the fixed handle 2 and the nailing handle 4 Between, and the movement direction of movable handle 3 and nail pressing handle 4 is consistent. The fixed handle 2, mo...

Abstract

The invention relates to a pair of operational separating forceps for matching a ureter. The pair of operational separating forceps mainly comprises a shell, a fixed handle, a movable handle, a nail pressing handle, a nail resisting base, a nail cabin, a nail pressing plate, a separating pull rod, a nail pressing pull rod and a telescopic connecting rod mechanism. The operational separating forceps disclosed by the invention can be used for separating tissues under a laparoscope and matching the ureter; and moreover, the surgical reliability is enhanced remarkably, and the surgical time is shortened remarkably.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a laparoscopic separation forceps which can be used for ureteral anastomosis. Background technique [0002] During ureteral surgery, since the ureter is located in a special position behind the peritoneum, no matter open surgery or laparoscopic surgery, ureteral anastomosis is very difficult, especially for laparoscopic ureteral anastomosis, which requires a lot of proficiency for urologists. high. Moreover, the reliability of anastomosis is far less than that of open surgery. The existing gastrointestinal stapler and blood vessel stapler cannot be used to anastomose the ureter due to size and structure problems, resulting in greater difficulty in anastomosis of the ureter and longer operation time. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the above technical problems, to provide a kind of surgical separation f...
