Specific embodiment

In order to be clearer and more clear technical problem to be solved in the utility model, technical solution and beneficial effect, with Under in conjunction with the accompanying drawings and embodiments, the present invention will be further described in detail.

Refering to fig. 1 shown in -2, the utility model includes casing 2 and is arranged in casing 2 about a kind of puncture outfit The outer end of needle core 1, needle core 1 is equipped with puncture tip 7, also includes spring 3 and key 4, and the both ends of described sleeve pipe 2 are to open face, key 4 It is arranged in one end of casing 2 and extends to outside casing 2, the inner end of key 4 is connect with the inner end of needle core 1, and the setting of spring 3 is being pressed Between key 4 and needle core 1, the puncture tip 7 is the puncture tip 7 in coniform shape, other end extension of the puncture tip 7 along casing 2 It stretches, the surface of puncture tip 7 is equipped with groove 6, and the groove 6 extends along the point of puncture tip 7, under natural conditions, the groove 6 Inside casing 2.

The use principle of the utility model:

Puncture outfit band line puncturing tissue is pierced by peritonaeum after reaching predetermined point, promotes needle core 1 to expose groove 6 by key 4, And suture is trapped in intraperitoneal, the reset of subsequent spring 3 makes puncture outfit condensation in casing 2, again to tying the another of tissue Side punctures, and after penetrating peritonaeum by original predetermined point, again promotes needle core 1, indwelling is arranged again in intraperitoneal suture On the surface of groove 6, puncture outfit takes suture in vitro out of after leaving peritonaeum, to complete operating procedure, it is complete to reach once-through operation It is punctured and the effect outside wiring lead body at line.

Refering to shown in Fig. 3-4, further, described sleeve pipe 2 includes anterior cannula 21, rear sleeve 22, and the one of anterior cannula 21 End is equipped with extension 23, and the extension 23 is connect as the outside extending obliquely in the center of circle and using the end face of front tube with rear sleeve 22, The rear sleeve 22, extension 23, anterior cannula 21 are sequentially connected to, and accommodating space 5, bullet are formed between rear sleeve 22 and extension 23 Spring 3, key 4 are arranged in accommodating space 5；It using the above scheme, can be quick to needle core 1 using anterior cannula 21 and rear sleeve 22 Assembly.
