Abstract

The invention discloses a four-claw bone-holding reposition and fixation device which is used for reposing and fixing bones. The four-claw bone-holding reposition and fixation device comprises two intersectant handles, wherein two handles are mutually hinged; the head ends of two handles are respectively provided with a big clamping claw and a small clamping claw; the inner surface of the big clamping claw and the inner surface of the small clamping claw are provided with anti-skidding knurls; the tail ends of the two handles are provided with elastic lock catches; each elastic lock catch comprises a flexure strip fixedly connected with one handle; the handle corresponding to the free end of the flexure strip is hinged with an elastic lock catch tooth; one end of the elastic lock catch tooth contacts the flexure strip; the tail end of the other handle is provided with a U-shaped tooth socket; and the U-shaped tooth socket corresponds to the free end of the elastic lock catch tooth.

Description

Four paws is held the reduction holder

Technical field

The present invention relates to a kind of medical supplies, relate in particular to a kind of four paws and hold the reduction holder.

Background technology

Along with the development of economic society, industry, building and traffic be constantly development also, and the fracture that various industrial injuries, Falling Injury and traffic accident cause is more and more, particularly the comminuted fracture of limb long tubular bone; Though medical apparatus and instruments keeps reforming innovation, medical level improves constantly, but resetting temporarily, controlling of fracturing in the operation process is fixing, traditional medical apparatus and instruments is slightly inadequate, the general use of present this operation is the three-jaw bone holder, the three-jaw bone holder is inserted difficulty, wound is big, union of fracture is slow, during application and often have a pawl to be positioned at fracture, the bit line of fracture end is observed in influence, and the three-jaw bone holder of multiple improvement, multi-functional pressurization bone holder, structure is complicated, the need both hands are finished and are held bone, reset, fixing operation, waste time and energy, and result of use is poor.

Summary of the invention

Good four paws is held the reduction holder to the purpose of this invention is to provide a kind of result of use.

For achieving the above object, the technical solution used in the present invention is: a kind of four paws is held the reduction holder, comprise two crossing handles, two handles are hinged, it is characterized in that: the head end of described two handles has designed big pawl of clamping and clamping unguiculus respectively, the big pawl of clamping, clamping unguiculus and handle are as a whole, the inner surface design of big pawl of clamping and clamping unguiculus has the skid resistance annular knurl, the tail end of two handles designs flexible snap close, elastic lock comprises flexure strip, flexure strip is fixedlyed connected with one of them handle, the place is hinged with the snap lock buckle teeth with the corresponding handle of the free end of flexure strip, one end of snap lock buckle teeth contacts with flexure strip, and the tail end of another handle has " U " shape teeth groove, and " U " shape teeth groove is corresponding with the free end of snap lock buckle teeth.

In this structure, the big pawl of clamping is corresponding with the center line of clamping unguiculus.

Advantageous effect of the present invention is: because the head end of two handles of the present invention has designed big pawl of clamping and clamping unguiculus respectively, the inner surface design of big pawl of clamping and clamping unguiculus has the skid resistance annular knurl, the tail end of two handles designs flexible snap close, use good fixing effect of the present invention, can avoid fracture end to misplace repeatedly and further increase the weight of the damage of fracture end, shorten operating time, reduce the damage of soft tissue, help union of fracture, one-handed performance can be finished the clamping of fracture end, do not need manpower to control, can reduce because manpower is controlled the dislocation that causes fracture end after the fatigue, for clinical providing convenience fixed reliably, effect is satisfied, has bigger development prospect, be specially adapted to the basic hospital that the medical worker lacks, benefit and apply, this method has reduced the incidence rate of complication, has improved cure rate and patient's quality of life, has reduced medical expense, alleviated patient's financial burden, accepted by family numbers of patients easily, obtained good social benefit, for clinical operation resets, fixedly provide reliable operation to help, reduce patient's misery, improve therapeutic effect.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Fig. 2 is a user mode reference diagram of the present invention.

In the accompanying drawing: 1, " U " shape teeth groove; 2, clamping unguiculus; 3, skid resistance annular knurl; 4, the big pawl of clamping; 5, hands handle; 6, snap lock buckle teeth; 7, flexure strip.

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments:

The present invention such as Fig. 1, shown in 2, a kind of four paws is held the reduction holder, comprise two crossing handles 5, two handles 5 are hinged, it is characterized in that: the head end of described two handles 5 has designed big pawl 4 of clamping and clamping unguiculus 2 respectively, the big pawl 4 of clamping, clamping unguiculus 2 is as a whole with handle 5, the inner surface design of big pawl 4 of clamping and clamping unguiculus 2 has skid resistance annular knurl 3, the tail end of two handles 5 designs flexible snap close, elastic lock comprises flexure strip 7, flexure strip 7 is fixedlyed connected with one of them handle, the place is hinged with snap lock buckle teeth 6 with the corresponding handle of the free end of flexure strip, one end of snap lock buckle teeth 6 contacts with flexure strip, and the tail end of another handle has " U " shape teeth groove 1, and " U " shape teeth groove 1 is corresponding with the free end of snap lock buckle teeth 6; In the present embodiment, the big pawl 4 of clamping is corresponding with the center line of clamping unguiculus 2.

The big pawl 4 of clamping among the present invention is corresponding with the center line of clamping unguiculus 2, the big pawl of clamping is not corresponding with the clamping unguiculus, can fully fill the span of a man's arms when closing up, and strengthens chucking power, to the clamping of fracture, reset, fixing more firm, effective, and be applicable to the tubular bone fracture that big or small thickness is different; And the design of the tail end of handle has " U " the shape teeth groove, opposite side designs flexible snap close tooth, automatically pin after the clamping, one-handed performance can be finished, and reduces simultaneously to cause the dislocation of fracture end to be inclined to after manpower is controlled fatigue, makes things convenient for next step operation, squeeze into intramedullary pin, settle external fixer or steel plate, shorten operating time, reduce patient's anesthesia and operation risk.

Material of the present invention is rustless steel, use easily complete operation of the present invention; " U " shape teeth groove answers the tooth stria dark, is convenient to interlock, and automatically pins, and does not need manpower to control, and using this apparatus patient one hand, can to finish temporarily resetting of fracture fixing.
