Description

Straight rongeur

Technical field

This utility model relates to a kind of human synovial bony spur therapeutic device, specifically is a kind of straight rongeur of carrying out the bony spur operative treatment in human synovial, belongs to technical field of medical instruments.

Background technology

In the human synovial therapeutic process, human synovial tends to take place joint disease, and the time can cause bony spur, particularly athlete and old people for a long time, in therapeutic process, need excise the ossa articularia thorn.Prior art is with the operation of incision formula, carries out joint bony spur excision, and surgical technic requires high, the operation trouble, and it is full slowly that patient's wound recovers; Also useful arthroscope and pin cutter carry out joint bony spur excision, and surgical technic requires high, and the long trouble of operating time does not satisfy ideal surgical effect.This utility model basis medical skill experience has for many years remedied the deficiencies in the prior art.

The utility model content

Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of reasonable in design, the effective straight rongeur of easy to use, joint bony spur excision are provided.

The technical scheme in the invention for solving the above technical problem is: this straight rongeur, its characteristics are: comprise fixed handle, flexible handle, swinging plate, fixing clamp, active clamp, push rod, claw beam, the push rod slide, bowl type groove, kerve and chute, described fixed handle and flexible handle are rotationally connected by the handle connecting bolt, swinging plate is arranged on the flexible handle by the handle connecting bolt, the pusher slide cover for seat is on the fixed handle and between fixed handle and claw beam, claw beam one end and fixed handle welding, the other end is welded with fixedly clamp, push rod slides and is sleeved in the claw beam, have chute and kerve on the push rod, kerve snaps in swinging plate, chute snaps in the push rod slide, the bottom of active clamp by steady pin and fixedly clamp be rotationally connected, also be rotationally connected by push rod pin and push rod, be respectively arranged with a bowl type groove on described fixedly clamp and the active clamp, two engaged couplings of bowl type groove.

The bowl type trench bottom of fixedly clamp described in the utility model and active clamp also is respectively arranged with small opening.

This utility model compared with prior art has the following advantages: the design of clamp is a bowl type, when the broken bone of gripping, can not come off, and clamp design is atresia and porose two kinds, and foraminous clamp can make other liquid spill from the hole, is convenient to the healthcare givers and selects according to the focus situation.This utility model can also be applied to interior the stinging of other focus objects of other human bodies and cut, as muscular tumor, calculi in vivo etc.This utility model entire body adopts metal material to make, and can clean and high-temperature sterilization.

Fig. 2 be among Fig. 1 A-A to cutaway view.

Fig. 3 is this utility model small opening structural representation.

The specific embodiment

Referring to Fig. 1～Fig. 3, this utility model comprises fixed handle 1, flexible handle 2, swinging plate 3, handle connecting bolt 4, fixedly clamp 5, active clamp 6, push rod 7, claw beam 8, push rod slide 9, bowl type groove 10, kerve 11, chute 12, push rod pin 13, steady pin 14.

Fixed handle 1 and flexible handle 2 usefulness handle connecting bolts 4 are rotationally connected, and swinging plate 3 usefulness handle connecting bolts 4 are fixed on 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, an end of claw beam 8 and fixedly clamp 5 welding is fixing, and the other end is fixed with fixed handle 1 welding.Push rod 7 is inserted in claw beam 8, and kerve 11 snaps in swinging plate 3 and can spur, and chute 12 snaps in push rod slide 9 and can slide, and push rod 7 can slide on claw beam 8.The bottom of active clamp 6 is rotationally connected with steady pin 14 and fixing clamp 5, and the bottom of active clamp 6 is rotationally connected with push rod pin 13 and push rod 7, fixedly has a bowl type groove 10 on clamp 5 and the active clamp 6, and bowl type groove 10 was identical mutually when clamp clamped mates.Fixedly bowl type groove 10 bottoms of clamp 5 and active clamp 6 also are respectively arranged with small opening 15.

The designed bowl type groove 10 of this utility model is divided into atresia and porose two kinds, and in operation was used, clamp clamped bony spur, and the clamp that is bowl type clamps and forms ellipsoid, and broken bone can arbitrarily not come off in ellipsoid; If also have liquid from small opening, to spill in the clamp, be convenient to the healthcare givers and select to use according to the focus situation.

Above content described in this description only is to the explanation of this utility model structure example.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.
