Utility model content

The utility model purpose is to provide a kind of new upper clamp device, to solve clamp clamping blood vessel mistake in the prior art Cheng Zhong, clamp are not easy that upper folder and folder close release and upper folder surgical procedure clamp comes off problem.Realize and take folder, folder to close tissue mistake Journey positions around；Enter clamp closure control when pressing from both sides；Clamp ejection comes off when folder closes release.Solves daily hysteroscope The technical bug of operation, so as to improve the safety and effectiveness of operation.

What the technical solution of the utility model was realized in：

A kind of new upper clamp device, including the clamp of caliper and V-arrangement, the clamp includes upper clamp holder and lower clamp holder, described Caliper includes upper plier handle and lower plier handle, and the tip inside of the upper plier handle and lower plier handle is provided with neck, the upper clamp holder and lower folder The end of handle is correspondingly provided with projection with neck, and the projection is abutted with neck, and the upper clamp holder is corresponding with the end of lower clamp holder to be set Locking mechanism is equipped with, is provided with a shell fragment on the inside of the caliper, described shell fragment one end is fixedly connected with upper plier handle or lower plier handle, the bullet The other end of piece is free end, and the stage casing of the shell fragment abuts clamp bottom and gives elastic force of the bottom one to jaw direction

Preferably, the shell fragment and the abutting part of clamp bottom are provided with stopper slot, and the clamp bottom can be along the stopper slot Length direction moves.

Preferably, the locking mechanism includes latch hook on lock and the lower clamp holder on upper clamp holder termination, and the caliper is stung During conjunction, the lock is caught in latch hook, discharges caliper, stuck upper clamp holder and the lower tear-away caliper of clamp holder.

Preferably, the inner side of the clamp is provided with anti-slop serrations.

Compared with prior art, the utility model has following beneficial effect：

New upper clamp device of the present utility model, shell fragment is internally provided with caliper, after upper clamp holder and lower clamp holder are stuck, Clamp can be ejected caliper by shell fragment, facilitate the release of clamp, be brought great convenience to surgical procedure and safe；Shell fragment and The stopper slot of shell fragment can prevent clamp movement with four-way positioning and close success rate to improve folder in operation；The bottom of shell fragment and caliper card Groove can feel the closure degree of pliers, the entrance of favourable tape clamp body.

Brief description of the drawings

Fig. 1 is the structural representation of new upper clamp device of the present utility model；

Fig. 2 is the left view of clamp and shell fragment in Fig. 1.

In figure：Caliper 1, upper plier handle 11, lower plier handle 12, neck 13, anti-slop serrations 14, lower plier handle groove 15, clamp 2, upper folder Handle 21, lower clamp holder 22, lock 23, latch hook 24, shell fragment 3, stopper slot 4.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the utility model is clearly and completely described.

As shown in Figure 1 and Figure 2, a kind of new upper clamp device, includes the clamp 2 of caliper 1 and V-arrangement, and the clamp 2 includes upper Clamp holder 21 and lower clamp holder 22, lower plier handle groove 15, the caliper 1 include upper plier handle 11 and lower plier handle 12, the upper plier handle 11 with The tip inside of lower plier handle 12 is provided with neck 13, and the end of the upper clamp holder 21 and lower clamp holder 22 is correspondingly provided with convex with neck 23 Rising, projection abuts with neck 13, and the neck 13 is spacing for upper clamp holder 21 and lower clamp holder 22, when clamp 2 is opened, Projection is connected in neck 13, and the end of the upper clamp holder 21 and lower clamp holder 12 is correspondingly arranged on locking mechanism, in the caliper 1 Side is provided with a shell fragment 3, and described one end of shell fragment 3 is fixedly connected with upper plier handle 11 or lower plier handle 12, and the other end of the shell fragment 3 is freely End, bottom journey circular arc, its can with the groove 15 of lower plier handle 12 slidably, the stage casing of the shell fragment 3 abut clamp bottom and Elastic force to from the bottom one to jaw direction, when upper clamp holder 21 is engaged with lower clamp holder 12 by locking mechanism, shell fragment 3 is then to folder The elastic force of body 2 one, clamp 2 is set to eject caliper 1.The shell fragment 3 and the abutting part of the bottom of clamp 2 are provided with stopper slot 4, the clamp 2 Bottom can move along the length direction of stopper slot 4, and the stopper slot avoids clamp 2 and moved left and right relative to caliper 1.The clamping lock Mechanism includes latch hook 24 on the lock 23 and lower clamp holder 22 on the upper termination of clamp holder 21, when the caliper 1 is engaged, the lock 23 It is caught in latch hook 24, discharges caliper 1, stuck upper clamp holder 21 and the tear-away caliper 1 of lower clamp holder 22, wherein lock 23 and latch hook 24 Profile can be made into above-mentioned projection.The inner side of the clamp 2 is provided with anti-slop serrations 14, and the anti-slop serrations 14 can prevent the blood vessel clamped Come off or mobile.Lower plier handle groove 15 on the applicator is provided with the spacing of the closure of clamp 2 with shell fragment bottom into circular arc Sense of touch structure.

To sum up structure of the present utility model is understood, new upper clamp device of the present utility model, is realized and is taken the front and rear, left of folder Right positioning；Enter haptic device when pressing from both sides；Shell fragment is internally provided with caliper, after upper clamp holder and lower clamp holder are stuck, shell fragment can incite somebody to action Clamp ejects caliper, facilitates the release of clamp, is brought great convenience to surgical procedure and safe.
