Abstract

The utility model discloses a reusable suture instrument for skin operations, belonging to the technical field of a medical appliance. The utility model comprises a needle pressing appliance and a suture needle box, wherein, the needle pressing appliance has a straight pressing type structure. In the utility model, an upper handle and a lower handle use a connection shaft as a fulcrum; a plate spring forms a stress structure; a triangular front guide shelf and a triangular back guide shelf are arranged on the lower handle; tubular guide grooves are formed at the clearance gaps of the guide shelves; the back guide shelf forms a right-angle triangular body the front plane of which forms the back guide groove face of a guide block; an inclined plane is parallel with a sliding groove face which is arranged in the lower handle; as a result, a convex pipeline face is formed so that positioning for introduction and extraction can be carried out for the suture needle box at replacing time, and other easily damaged parts can be replaced.

Description

Reusable operation on skin stiching instrument

This utility model belongs to technical field of medical instruments, further relates to the surgical stapler that uses in a kind of clinical operation on skin.

At present, the single-use skin surgical stapler of clinical use is applicable to postoperative epidermis stitching, has good sewing effect, and healing of wound is neat, tiny, attractive in appearance, and is simple to operate, safe, reliable.But the effective rate of utilization of device material is low, and garbage is many, and use cost is higher.

But the purpose of this utility model is to provide a kind of operation on skin stiching instrument of repeated disinfection use.

This utility model comprises pressing apparatus and box of suture needles, and the pressing apparatus is the direct press type structure, and upper handle and lower handle are rotating fulcrum with the coupking shaft, and it is subjected to force mechanisms is spring.Lower handle is equipped with front guide bracket and back saddle, and the front and back saddle is all triangular in shape fits with lower handle.The space is the tubulose guide groove between the saddle of front and back.The rectangular triangle body of back saddle, its frontal plane constitutes the back guide groove face of guide block, and the inclined-plane is parallel with the inner chute face of lower handle, constitutes the convex pipe surface, uses guide rail as changing for box of suture needles.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is an overall structure sketch map of the present utility model.

Fig. 2 is the structural representation of this utility model box of suture needles.

This utility model upper handle 1 and lower handle 2 are through coupking shaft 5 active connections.Upper handle 1 and lower handle 2 cross sections are Type or square form a direct press type structure.Front guide bracket 3 and back saddle 9 are installed on the lower handle 2.The top of front guide bracket 3 has connecting pore, and this hole and coupking shaft 5, lower handle 2, upper handle 1 run through connection.Front guide bracket 3 is the triangle body shape, and its frontal plane and two sides and lower handle 2 front ends are fitted.The triangle body back plane constitutes the front guide slot of guide block 6 and the blocking surface of box of suture needles 11.Back saddle 9 rectangular triangle bodies, it is the triangle body shape that saddle 3 is pasted with back saddle 9 inner side plane in its both sides, its frontal plane and two sides and lower handle 2 front ends are fitted.The triangle body back plane constitutes the front guide slot of guide block 6 and the blocking surface of box of suture needles 11.Back saddle 9 rectangular triangle bodies, fit with back saddle 9 inner side plane in its both sides, and its frontal plane constitutes the back guide groove face of guide block 6, and the inclined-plane is parallel with lower handle 2 inner chute faces, constitutes the convex pipeline, frees in and out and locatees for box of suture needles 11.

Guide block 6 is circular arc head rectangle cube, and head is that the medial surface of upper handle 1 joins, and is pressure-bearing surface.The centre is established towing pad, is run through upper handle 1 and guide block 6 by leading axle 7, and its axle center is a fulcrum.The lower end mid-plane of guide block 6 is fixed or be riveted on to eedle presser 10.Riveted holes is arranged at eedle presser 10 tops, and the lower end is

Shape,

Circular arc or bench-type groove are all arranged at template inboard and bottom.Leaf spring 8 is the C type, and two kinds of fixing meanss are arranged: one, be fixed in the inner plane of upper handle 1.And the rear end reinforcing of the box of suture needles 11 that skewer is gone into, make it in lower handle 2, keep steady statue.Two, place front guide bracket 3 around coupking shaft 5, skewer is gone into guide block 6, and these two kinds of structures all can make upper handle 1 upspring, and make upper handle 1 and lower handle 2 keep certain angle.

Box of suture needles 11 is by guide board 16, sewing needle 18, and needle pushing plate 15, constant force spring 14, upper cover plate 12, lower cover 13 and spring cover plate 17 are formed.Guide board 16 cross sections are bench-type, and front end has the retaining needle latch.Arrangement as sewing needle 18 relies on.Sewing needle 18 is The thin stainless steel silk of type, two pin ends are wedgelike.Sewing needle 18 is tight regular arrangement on guide board 16, by needle pushing plate 15 they is pushed forward to the retaining needle latch and lower cover 13 inner planes of guide board 16.Needle pushing plate 15 cross sections are Type straddles on the guide board 16.Front end is the inclined-plane makes sewing needle 18 all be in heeling condition, and there is erected piece the rear end, is subjected to constant force spring 14 tractions to make needle pushing plate 15 press sewing needle 18 forward.Constant force spring 14 is a dumbbell shaped, is two helical springs that link to each other, and link fastens needle plate 15 rear ends.

Upper cover plate 12 bodies are

Type, end face have constant force spring 14 and needle pushing plate 15 employed guide groove and fixed frames.Front end has the center guide groove and two side guidances of eedle presser 10, and voltage supply needle plate freedom accurately slides up and down.

Lower cover 13 cross sections are matrix, and front end has eedle presser baffle plate and needle outlet.It combines closely guide board 16, upper cover plate 12 threes by the negative and positive location structure.

The bossing that spring reed 17 is stuck in upper cover plate 12 prevents that constant force spring 14 from coming off.

Frame for movement of the present utility model meets following formula:

The utility model has following benefit except keeping the disposable skin stapler advantage:

(1) disposable use cost is low, and patient's financial burden is little; (2) discarded object Few, environmental pollution is little; It is (3) applicable in GENERAL TYPE suture needle and wide type suture needle, Be suitable for respectively thin type patient and fat type patient or the thick position of fat; (4) just In changing box of suture needles and easily worn part; (5) structural design is simple, light and handy.
