The pair of propping forceps is characterized by being provided with a first handle, a second handle, two clips, a toothed plate, a pressure spring and two springs, wherein the first handle and the second handle are rotatably connected by a fixed screw; the two clips are respectively fixed on the first handle and the second handle; the two clips are provided with arc grooves and extend to two sides; the two springs are pressed mutually and respectively fixed on the first handle and the second handle; the toothed plate is provided with racks; the toothed plate penetrates the first handle and is rotatably connected with the second handle; the first handle is provided with clamping teeth; the pressure spring is fixed on the second handle; the pressure spring is sheathed in the toothed plate and clamps the clamping teeth in the racks; the two clips are hook-shaped; and the toothed plate is rotatably connected with the second handle through a fixed pin. As for the propping forceps, the clamping teeth and the racks are matched under the action of the pressure spring and are clamped tightly, thus leading to a fixed opening between the two clips; and the propping forceps have simple structure and low cost, and is convenient and practical.

Description

Strut pincers

Technical field:

This utility model relates to a kind of human body and opens the abdomen operation, be exclusively used in out that the abdomen operative incision struts strut pincers.

Background technology:

Open in the abdomen operation process at human body, need otch to strut, particularly small incision surgery helps getting a clear view in the body, needs special-purpose otch distraction instrument.Prior art is opened the abdomen operative incision to human body and is strutted, there is not special equipment, carrying out the gripping otch with general pincers class opens to otch, its defective is that the operation application does not match, particularly little otch, otch open just more inconvenient, easily cause the otch damage, the effect of influence operation and prolongation operating time do not satisfy ideal surgical effect.

Summary of the invention:

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, struts and provide a kind of human body to be exclusively used in out the abdomen operative incision, and particularly small incision surgery struts struts pincers.

This utility model solves the problems of the technologies described above the technical scheme that is adopted: this struts pincers, it is characterized in that being provided with first handle, second handle, two binding clips, tooth plate, stage clip, two springs, first handle, second handle is rotationally connected by fixed screw, two binding clips are separately fixed on first handle and the second handle, two binding clips have arc shaped groove and stretch out to both sides, two springs compress mutually and are separately fixed on first handle and the second handle, tooth plate has tooth bar, tooth plate passes first handle and second handle is rotationally connected, first handle has latch, stage clip is fixed on the second handle, and stage clip is inserted in tooth plate latch is snapped in tooth bar.

Two binding clips of this utility model are hook.

This utility model tooth plate is rotationally connected by steady pin and second handle.

This utility model struts pincers and adopts metal material to make.

This utility model latch and tooth bar mate under the effect of stage clip and coincide, and chucking mutually, make two fixed amplitude that binding clip struts, and simple in structure, convenient and practical, cost is low.

Description of drawings:

Fig. 1 is the structural representation of this utility model embodiment.

Fig. 2 is the tong head sketch map of this utility model embodiment.

Fig. 3 is that the A of Fig. 1 binding clip is to view.

The specific embodiment:

Referring to Fig. 1～Fig. 3, this utility model embodiment struts the design of wrench structure and uses the circular arc type binding clip, and otch is strutted, and effectively exposes the visual field in the body, guarantees carrying out smoothly of operation.Strut pincers and be provided with first handle 1, second handle 2, screw 3, fixed screw 4, binding clip 5, arc shaped groove 6, tooth plate 7, tooth bar 8, latch 9, stage clip 10, steady pin 11, spring 12.First handle 1, second handle 2 usefulness fixed screws 4 connect and can rotate, two binding clips 5 be hook have arc shaped groove 6 (referring to Fig. 3) and be welded on first handle 1 and second handle 2 on; Two springs 12 compress mutually with screw 3 and are separately fixed on first handle 1 and the second handle 2; Tooth plate 7 has tooth bar 8, tooth plate 7 passes first handle 1 usefulness steady pin 11 and is fixed on the second handle 2 and can rotates, first handle 1 has latch 9, stage clip 10 usefulness screws 3 are fixed on the second handle 2, stage clip 10 is inserted in tooth plate 7 just it is compressed, and latch 9 snaps in tooth bar 8 couplings coincide (referring to Fig. 1) just.Two the handle binding clips 5 of holding with a firm grip strut (Fig. 2), and under the effect of latch 9 and tooth bar 8, two binding clips 5 are according to the fixed amplitude that struts; Move down tooth plate 7, latch 9 and tooth bar 8 thrown off, and under the effect of spring 12, two handles and binding clip 5 reset.

This utility model struts pincers, designed latch 9 and tooth bar 8 mate identical under the effect of stage clip 10, and tighten mutually, strut in the application opening the abdomen operative incision, binding clip 5 is inserted in otch, as long as two binding clips 5 of two handles of holding with a firm grip promptly strut, under the effect of latch 9 and tooth bar 8, two binding clips 5 can never arbitrarily injure human body otch and organ-tissue according to the fixed amplitude that struts.

This utility model struts pincers, designed binding clip 5 has arc shaped groove 6, and design has kind and the specification that varies in size, the healthcare givers struts in the application at operative incision, the healthcare givers selects to use according to the size of otch and struts pincers, and in the arc shaped groove 6 that struts, undergo surgery, greatly facilitate operation technique, guarantee carrying out smoothly of operation.

This utility model struts pincers and adopts metal material to make, and can use the disinfectant solution irrigation and disinfection, also can use high-temperature sterilization.

The simple deformation of this utility model technical characterictic or technical scheme and combination should be thought to fall into protection domain of the present utility model.
