Abstract

The utility model relates to a human body laparotomy surgery, in particular to a pair of propping-open forceps specially used for propping open a cut in laparotomy surgery, belonging to the mechanical field of medical devices. The propping-open forceps consist of a first handle, a second handle, a screw, a fixed screw, forceps heads, a toothed plate, a rack, clamping teeth, a pressure spring, a fixed pin and springs, wherein the first handle and the second handle are connected by the fixed screw, two forceps heads are welded on the first handle and the second handle, two springs are pressed mutually and are respectively fixed on the first handle and the second handle by the screw; the rack is arranged on the toothed plate, the toothed plate is fixed on the second handle by the fixed pin after penetrating through the first handle, the clamping teeth are arranged on the first handle, and the pressure spring is fixed on the second handle by the screw. The propping-open forceps has the characteristics that the structural design is reasonable, the visual field inside the human body can be effectively exposed, and the operation can be ensured to be carried out successfully.

Description

A kind of pincers that strut

Technical field

This utility model relates to human body and opens the abdomen operation, is exclusively used in out the pincers that strut that the abdomen operative incision struts, and belongs to the medical device technology mechanical field.

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 provide a kind of reasonable in design, effectively expose the visual field in the body, guarantee operation carry out smoothly strut pincers.

It is that this struts pincers that this utility model solves the problems of the technologies described above the technical scheme that is adopted, its construction features is: be made up of first handle, second handle, screw, fixed screw, binding clip, tooth plate, tooth bar, latch, stage clip, steady pin, spring, described first handle is connected with fixed screw with second handle, and two binding clips are welded on first handle and the second handle; Two springs compress mutually with screw and are separately fixed on first handle and the second handle; Tooth plate has tooth bar, and tooth plate passes first handle and is fixed on the second handle with steady pin, and first handle has latch, and described stage clip is screwed on second handle.

Binding clip described in the utility model is hook and has arc shaped groove.

The whole metal material that adopts of this utility model is made.

This utility model is compared with prior art and is had the following advantages and effect: in small incision surgery, use the circular arc type binding clip, otch is strutted, effectively expose the visual field in the body, guarantee carrying out smoothly of operation.This utility model design strut pincers, be that metal material is made, can use the disinfectant solution irrigation and disinfection, also can use high-temperature sterilization.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A of Fig. 1 is to sketch map.

Structural representation when Fig. 3 opens for this utility model binding clip.

Label declaration: 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.

The specific embodiment

Below in conjunction with embodiment this utility model is described in further detail, following examples are to explanation of the present utility model and this utility model is not limited to following examples.

Embodiment 1: as shown in Figures 1 to 3, present embodiment is made up of 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.

Annexation is: first handle 1 and second handle 2 usefulness fixed screws 4 are connected and fixed and can rotate, two binding clips 5 be hook have arc shaped groove 6 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, and first handle 1 has latch 9, and stage clip 10 usefulness 3 screws 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 just and coincide.The handle of holding with a firm grip, binding clip 5 struts, and under the effect of latch 9 and tooth bar 8, binding clip 5 is according to the fixed amplitude that struts; Move down tooth plate 7, latch 9 and tooth bar 8 are thrown off, and under the effect of spring 12, handle and binding clip 5 reset.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 hold handle with a firm grip, binding clip 5 struts, under the effect of latch 9 and tooth bar 8, binding clip 5 can never arbitrarily injure human body otch and organ-tissue according to the fixed amplitude that struts.

This utility model design strut 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 in the arc shaped groove 6 that struts, undergo surgery, greatly facilitate operation technique, guarantee carrying out smoothly of operation.

This utility model design strut pincers, be that metal material is made, can use the disinfectant solution irrigation and disinfection, also can use high-temperature sterilization.

In addition, need to prove, the specific embodiment described in this description, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of this utility model patent according to this utility model patent.This utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
