The rongeur comprises a fixed handle, a moving handle, a shifting plate, pressure springs, a push bar, a rongeur lever, a push bar slide carriage, a fixed jaw and a moving jaw. The rongeur is characterized in that the push bar is sleeved to the rongeur lever and is provided with a slide groove and a pull groove, the push bar slide carriage is clamped in the slide groove, and the shifting plate is clamped in the pull groove. The rongeur overcoming the defects in the prior art has the advantages of reasonable and simple structural design, effectiveness in gouging joint spurs, flexibility and safety in surgical application and the like.

Description

Rongeur

Technical field

This utility model relates to a kind of medical calm, particularly a kind of rongeur, and it mainly is applicable to the bony spur treatment of human synovial connecting portion, belongs to medical instruments field.

Background technology

In the human synovial treatment, find that the joint connecting portion tends to take place joint disease, the time can cause bony spur, particularly athlete and old people for a long time.In therapeutic process, need excise the bony spur of joint connecting portion.Prior art is with the operation of incision formula, carries out joint bony spur excision, and surgical technic requires high, and troublesome poeration, patient's wound recover slow; Also useful arthroscope and pin cutter carry out joint bony spur excision, and same surgical technic requires high, and operating time is long, can not obtain satisfied surgical effect.

Summary of the invention

This utility model technical problem to be solved is to overcome existing above-mentioned deficiency in the prior art, and a kind of rongeur is provided, and makes joint connecting portion bony spur sting cut effective.

This utility model solves the problems of the technologies described above the technical scheme of being taked: this rongeur; Comprise fixed handle, flexible handle, swinging plate, stage clip, push rod, claw beam, push rod slide, fixedly clamp and active clamp; Its construction features is: described push rod and claw beam socket; Have chute and kerve on the push rod, card has the push rod slide in the described chute, and card has swinging plate in the kerve.

This utility model rongeur, described fixedly clamp has folder hole.

This utility model is compared with prior art, has the following advantages and effect: reasonable in design, simple, and joint connecting portion bony spur is stung cut effective; Fixedly have folder hole on the clamp, active clamp is the cutter type, and active clamp snaps in folder hole coupling and coincide to form to sting and cut the flexible safety of surgical application.

Among the figure: 1 fixed handle, 2 flexible handles, 3 swinging plates, 4 handle connecting bolts, 5 stage clips, 6 fixed screws, 7 push rods, 8 claw beams, 9 push rod slides, 10 fixing clamps, 11 kerves, 12 chutes, 13 active clamps, 14 folder holes, 15 clamp pins, 16 push rod pins.

The specific embodiment

Embodiment to this utility model is described further below in conjunction with accompanying drawing, and present embodiment provides detailed embodiment and concrete operating process, but the protection domain of this utility model is not limited to following embodiment.

Referring to Fig. 1～Fig. 3, the fixed handle 1 of this utility model is connected with flexible handle 2 usefulness handle connecting bolts 4, can rotate; Swinging plate 3 usefulness handle connecting bolts 4 are fixed on the flexible handle 2, and two stage clips 5 compress mutually with fixed screw 6 and are separately fixed on fixed handle 1 and the flexible handle 2; It is fixing with fixed handle 1 welding that push rod slide 9 is inserted in fixed handle 1 back claw beam 8; Push rod 7 has chute 12 and kerve 11, and fixedly clamp 10 has folder hole 14, and an end of claw beam 8 is with fixedly clamp 10 welding are fixing, and the other end and fixed handle 1 weld to be fixed; One side of the low side of active clamp 13 is fixed on fixedly on the clamp 10 with clamp pin 15, can rotate, and another side is fixed on the push rod 7 with push rod pin 16, can rotate; Push rod 7 is inserted in claw beam 8, and swinging plate 3 snaps in kerve 11, can spur, and push rod slide 9 snaps in chute 12, can slide; Push rod 7 can slide on claw beam 8.

Flexible handle 2 as long as this utility model is held with a firm grip, and swinging plate 3 is stirred push rod 7, and push rod 7 promotes active clamp 13, active clamp 13 and fixedly clamp 10 clampings.In surgical application, under the motive force effect of push rod 7, it is big that clamp clamps strength, can sting the bony spur of cutting the joint connecting portion; Sting cut end after, release handle under the effect of stage clip 5, clamp automatically resets.

The active clamp 13 of this utility model and the fixing design ovalize of clamp 10; Fixedly clamp 10 has folder hole 14; Active clamp 13 is the cutter type, and active clamp 13 snaps in folder hole 14 coupling and coincide to form to sting and cut, and the clamp of ovalize can guarantee to sting the smooth surface of cutting the position stinging to hit.

This utility model is made with metal material, can clean and high-temperature sterilization.
