Abstract
This utility model belongs to medical apparatus and instruments, discloses a kind of novel vascular tweezer, and it comprises two tweezer arms, and two tweezer arm lower ends are provided with the bare terminal end of drawing close to centre, are provided with a V-arrangement shell fragment between two bare terminal ends; Down, the both ends of top are fixed on two tweezer arms by positioning seat at described V-arrangement shell fragment tip, and described positioning seat is provided with holding screw; V-arrangement shell fragment and form Y shape clamping gap between the bare terminal end of its both sides.It is conducive to inserting needle, threading, is convenient to blood vessel docking and coincide, and it has reduced vascular anastomosis difficulty greatly, has improved stitching precision and operating efficiency, has significant practicality.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of novel vascular tweezer.
Background technology
While carrying out vascular suture clinically, generally adopt vascular clamp to clamp blood vessel wall and sew up.While adopting current vascular clamp to sew up, blood vessel wall is close together, and very inconvenient inserting needle threading, has increased vascular anastomosis difficulty, affects operation technique efficiency and vascular suture quality.In addition, two tweezer lobes of current vascular clamp be all by bring in tension force be provided, the open-shaped state in the amount of making tweezer lobe lower end, its expansionary force providing is less, and diminish gradually along with the growth of service time, tweezer lobe can not be opened smoothly, when especially tweezer lobe both sides are provided with the formation obstacles such as tissue, be more not easy to clamp, unclamp operation.
Utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure, reasonable in design, convenient to operation that this utility model provides, and reduces vascular anastomosis difficulty, improves the novel vascular tweezer of suture quality and operating efficiency.
For realizing above-mentioned technical purpose, this utility model adopts following scheme: a kind of novel vascular tweezer, comprise the tweezer arm that two upper ends link together, two tweezer arm lower ends are provided with the bare terminal end of drawing close to centre, it is characterized in that: between two bare terminal ends, be provided with a V-arrangement shell fragment; Down, the both ends of top are fixed on two tweezer arms by positioning seat at described V-arrangement shell fragment tip, and described positioning seat is provided with holding screw; V-arrangement shell fragment and form Y shape clamping gap between the bare terminal end of its both sides.
The utlity model has following beneficial effect: it is in clamping when blood vessel, blood vessel wall can be clamped Y-shapedly, be more conducive to inserting needle, threading, be convenient to blood vessel docking and coincide, it has reduced vascular anastomosis difficulty greatly, has improved stitching precision and operating efficiency; V-arrangement shell fragment can provide suitable expanded support power to two tweezer lobes simultaneously, and tweezer lobe can be opened smoothly, operates to facilitate, and it has significant practicality.
