Description

The powerful jaw hole pincers of atresia

Technical field

This utility model relates to a kind of human synovial bony spur therapeutic device, specifically is a kind of powerful jaw hole pincers of atresia that carry 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 powerful jaw hole pincers of atresia of flexible and convenient to use, joint bony spur excision are provided.

The technical scheme in the invention for solving the above technical problem is: the powerful jaw hole pincers of this atresia, its characteristics are: comprise fixed handle, flexible handle, swinging plate, stage clip, push rod, claw beam, the push rod slide, active clamp, fixing clamp, chute, kerve and push rod chute, fixed handle and flexible handle are rotationally connected by the handle connecting bolt, swinging plate is fixed on the flexible handle by the handle connecting bolt, be provided with stage clip by fixed screw respectively on fixed handle and the flexible handle, the pusher slide cover for seat is contained on the fixed handle, and between fixed handle and claw beam, claw beam and fixed handle welding, one end of chute and fixedly clamp welding is fixing, the other end and claw beam welding are fixing, the active clamp slip snaps in chute and is slidingly matched with chute, push rod and active clamp welding, have kerve and push rod chute on the push rod, the push rod slide slides and snaps in the push rod chute, and swinging plate slides and snaps in kerve.

This utility model compared with prior art has the following advantages: the flexible handle of holding with a firm grip, swinging plate is stirred push rod, and active clamp and fixedly clamp clamping clamp clamp the strength maximization of bony spur, generally sharp can press from both sides brokenly in that the people is intravital, press from both sides cutting to the bone after broken and can take out human body; Also can bite away cutting to the bone.Release handle under the effect of stage clip, clamp automatically resets, and is rational in infrastructure, and control is flexible, and this utility model adopts metal material to make, and can clean and high-temperature sterilization.

Fig. 3 be among Fig. 1 B-B to cutaway view.

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, stage clip 5, fixed screw 6, push rod 7, claw beam 8, push rod slide 9, active clamp 10, fixedly clamp 11, chute 12, kerve 13, push rod chute 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, 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.One end of chute 12 and fixedly clamp 11 welding is fixing, the other end is fixed with claw beam 8 welding.Push rod 7 has kerve 13 and push rod chute 14 and fixing with active clamp 10 welding, active clamp 10 snaps in chute 12, both mate the active clamp 10 that coincide and can slide on chute 12, and push rod slide 9 snaps in push rod chute 14 and can slide, and swinging plate 3 snaps in kerve 13 and can slide.

During use, as long as hold flexible handle 2 with a firm grip, swinging plate 3 is stirred push rod 7, active clamp 10 and fixedly clamp 11 clamp, make clamp clamp bony spur strength maximum, generally the people intravital sharp can press from both sides broken, press from both sides sharp after broken and can take out human body, also inferior bone can be bitten away.Unclamp flexible handle 2 under the effect of stage clip 5, clamp automatically resets.

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.
