Abstract
The utility model discloses the intracavity Endo-GIA that a kind of band is free nail bin to protect; the nail bin comprising nail bin frame and be arranged on nail bin frame; described nail bin rear portion is provided with ejector pin block; cutter and described ejector pin block are put up a bridge and can be promoted ejector pin grain; after ejector pin, ejector pin block stays nail bin front portion; described cutter both sides are provided with boss, and nail bin frame edge is provided with groove, cutter are provided with shell fragment boss being applied to the power made it have to concave slot sports trend.This utility model cannot carry out firing action under empty nail bin or the nail bin state pulled the trigger, solves because personnel neglect the safety problem caused.
Description
Technical field
This utility model relates to the intracavity Endo-GIA that a kind of band is free nail bin to protect, and belongs to medical instruments field.
Background technology
In minimal invasive surgical procedures, implement operation technique by the minimal incision * of patient or the narrow sleeve pipe of insertion wound, intracavity Endo-GIA can contact operative site than being easier to, and cuts art portion tissue and sews up.In order to avoid the maloperation because of doctor in the middle of operation; apparatus is unkitted nail bin or the nail bin of having pulled the trigger is loaded apparatus again; only tissue is cut and can not sew up after percussion; and cause losing blood; the phenomenon increasing the risk of operation occurs; need to arrange the protection of sky nail bin, to improve instrumentation safety.
Summary of the invention
This utility model object is to provide the intracavity Endo-GIA that a kind of band is free nail bin to protect, and improves instrumentation safety.
For achieving the above object; the technical solution adopted in the utility model is: be with the intracavity Endo-GIA being free nail bin to protect; the nail bin comprising nail bin frame and be arranged on nail bin frame; described nail bin rear portion is provided with ejector pin block; cutter and described ejector pin block are put up a bridge and can be promoted ejector pin grain, and after ejector pin, ejector pin block stays nail bin front portion, and described cutter both sides are provided with boss; nail bin frame edge is provided with groove, cutter is provided with shell fragment boss being applied to the power made it have to concave slot sports trend.
Described shell fragment is " Contraband " font, and when shell fragment coordinates with cutter, two parallel edges are pressed on boss.
Remarkable advantage of the present utility model is; be with the intracavity Endo-GIA being free nail bin to protect; during percussion; push rod promotes push jack; also promote the cutter be connected with push jack simultaneously; cutter promote ejector pin block and travel forward, and cutter cut tissue, and ejector pin block travels forward and promotes ejector pin grain suturing nail is sewed up tissue.After stitching completes, ejector pin block is pulled to nail bin front end, cannot reset.If at this moment maloperation, again pull the trigger, cutter travel forward, cannot put up a bridge with ejector pin block, simultaneously because the counteracting force of shell fragment to boss makes the boss of cutter fall into the groove of nail bin frame, cutter block, and guarantee like this cannot carry out firing action under empty nail bin or the nail bin state pulled the trigger, serve safety effect, solve because personnel neglect the safety problem caused.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, makes advantage of the present utility model and feature can be easier to those skilled in the art and understand.
Be with the intracavity Endo-GIA being free nail bin to protect; comprise nail bin frame 6 and be arranged on the nail bin 1 on nail bin frame; described nail bin 1 rear portion is provided with ejector pin block 2, as shown in Figure 1, when cutter 4 and described ejector pin block 2 are put up a bridge; cutter 4 promote ejector pin block 2 and travel forward; cutter 4 cut tissue, and ejector pin block 2 travels forward and promotes ejector pin grain 3 and suturing nail is sewed up tissue, after stitching completes; ejector pin block 2 is pulled to nail bin 1 front end, cannot reset.
Cutter 4 both sides are provided with boss 41, and the edge of nail bin frame 6 is provided with groove 61, cutter 4 is provided with the shell fragment 5 described boss 41 being applied to the power made it have to described groove 61 movement tendency.Have employed " Contraband " font structure as a kind of optimal way shell fragment 5, when shell fragment 5 coordinates with cutter 4, two parallel edges are pressed on boss 41.If the nail bin of the complete nail of economy-combat is pulled the trigger by doctor's maloperation again, when cutter 4 travel forward, in the groove 61 that the effect lower convex platform 41 of shell fragment 5 falls at nail bin frame, cutter 4 are blocked, can not travel forward, thus can not carry out cutting and sewing up action.This design ensure that apparatus is unkitted nail bin under normal circumstances or loads used nail bin can not complete cutting and stitching action, thus improves the safety of instrumentation.
