Description

Fracture fixer

This utility model relates to a kind of medical apparatus and instruments of extremity fracture reduction external fixation, particularly a kind of fracture top folder reduction holder.

Bone fracture restitution fixator is that a kind of patient of making can in time obtain reliable reduction, fixing, healing after fracture, recovers the medical apparatus and instruments of quadruped locomotion function as early as possible.At present, the holder that generally uses generally belongs to external rigid fixation means both at home and abroad, complex structure, and volume is bigger, has both hindered patient's functional exercise, makes wrapping, the dressing of medical personnel in therapeutic process again, and use and dismounting are made troubles.The advanced external fixator that present stage uses, also exist following weak point as Chinese patent 90213092.7: this holder can only play the fixation on the same plane, be easy to generate the swing offset of fracture end during use, stability and adjustable are all poor, are unfavorable for that the patient gets well early.

The purpose of this utility model is intended to overcome above prior art and weak point and provide a kind of simple and light, and cost is low, stability and adjustable are good, and not influencing the patient carries out functional exercise, so that the fracture that the patient heals as early as possible top folder reduction holder.

The purpose of this utility model, reach in the following way: fracture top folder reduction external fixator is made up of metering needle, ring for fixing, plintlet and adjusting nut, caulking groove is arranged in the ring for fixing, the plintlet symmetry is installed in the caulking groove of ring for fixing, the front end of metering needle is a wedge, and its rear end is installed on the plintlet with adjusting nut by screw thread.

Front end for the ease of treatment oar chi fracture of both bones this utility model metering needle is from screw thread.

The further purpose of this utility model provides a kind of the top with fracture and presss from both sides the matching used reduction of the fracture traction apparatus of reduction external fixator, its technical solution is: reduction of the fracture traction apparatus is made up of expansion link, connection chain and fixing head, sliding seat is arranged on the expansion link, fixing head is installed in by bolt on the sliding seat of expansion link, and its two ends respectively are equipped with two ends by screw thread with screw and can be linked together with the connection chain of fixed limb with bolt.

For the ease of the patient is carried out X-ray examination during treating, so that correcting residual displacement at any time, plintlet of the present utility model is xyloid.

This utility model is owing to adopt as above design, compared with prior art, have simple and light, cost is low, and is easy for operation, the characteristics that fixed stability and adjustable are good, do not influence patient's functional exercise, since plintlet be xyloid and with the supporting use of traction apparatus, during treating, can carry out X-ray examination, so that correcting residual displacement at any time to the patient.

Embodiment one: fracture top folder reduction holder is by metering needle (1), ring for fixing (2), plintlet (3) and adjusting nut (4) are formed (as Fig. 1 Fig. 2 and shown in Figure 3), caulking groove (5) is arranged in the ring for fixing, the plintlet symmetry is installed in the caulking groove of ring for fixing, the front end of metering needle is wedge (as Fig. 4 Fig. 5 and shown in Figure 6), and the logical screw thread in its rear end is installed on the clamping plate with adjusting nut.Ring for fixing is a plastic ring, and plintlet is xyloid, and metering needle is medical Stainless Steel.Be connected chain (8) with the matching used traction apparatus of fracture top folder holder by expansion link (7) and fixing head (9) is formed, sliding seat (10) is arranged on the expansion link, fixing head is installed on the sliding seat on the expansion link by bolt, and its two ends respectively are equipped with two ends by screw thread with screw and can be linked together with the connection chain of fixed limb with bolt.

Using method: with the fracture near-end of fixed trap at patient's limbs, the rotation displacement of fracture is corrected in aseptic sterilization, under local anaesthesia or brachial plexus block anesthesia, prick metering needle, the first corresponding metering needle of pricking in plane on the fracture proximal end, metering needle only passes the still corresponding metering needle of pricking in a plane of a side seam matter, fracture far-end, metering needle also only passes a side seam matter, and the plane that makes the near-end metering needle becomes 90 degree (as shown in Figure 2) with angle α angle between the plane of far-end metering needle.The metering needle end of thread puts adjusting nut respectively.Hole in position according to metering needle on the plintlet, be enclosed within and make plintlet parallel on the adjusting nut with limbs, priority is near plintlet, distal head puts plastic ring and forms " squirrel-cage " fixed mount, the plintlet of near-end metering needle is screwed on plastic ring, the 3-4 layer that outside " squirrel-cage " fixed mount, twined binder, (the cotton pad of bag is installed two chains and two fixing heads with screw respectively on the limbs of " squirrel-cage " fixed mount two ends with the traction apparatus traction, the spacing of chain is fit to, fixing head fixation symmetry, then the sliding seat on the expansion link is installed on the fixing head with screw respectively, rotating extensible arm promptly draws), fracture keeps certain movable space, adjust metering needle then and make the reduction of the fracture, be screwed the plintlet on the far-end metering needle, the film making of X line is complicated, is shifted pine except that the plintlet screw on the far-end metering needle if any remnants, make the traction slightly of far-end fracture, adjust metering needle and promptly reach accurately multiple.(resetting the doctor with traction apparatus can be by X line loss wound body) corrected in be shifted feasible 1-2 film making or X line direct-view of correcting residual down.

Embodiment two: fracture top folder reduction holder is made up of (as figure metering needle (1), ring for fixing (2), plintlet (3), adjusting nut (4) and nut card (6), Fig. 7, Fig. 8, shown in Figure 9), caulking groove (5) in the ring for fixing, plintlet is installed in the caulking groove of ring for fixing, the front end of metering needle is tapping screw thread (as Figure 10, Figure 11, shown in Figure 12), and its rear end is installed on the plintlet with adjusting nut and nut card by screw thread.Ring for fixing is plastics, and plintlet is xyloid, and metering needle is a medical stainless steel.Press from both sides the structure of the matching used traction apparatus of holder with embodiment one with the fracture top.

Using method: with the fracture near-end of fixed trap at patient's limbs, the rotation displacement of fracture is corrected in aseptic sterilization, under local anaesthesia or brachial plexus block anesthesia, pricks metering needle.The radius and ulna fracture screws in metering needle and passes sclerotin in the fracture proximal end earlier, and far-end screws in metering needle equally, makes the β angle near, that the far-end metering needle forms become cross section 90 degree (as shown in Figure 8).The metering needle end of thread puts adjusting nut respectively, is enclosed within on the metering needle nut according to the boring of the position of metering needle on the plintlet and fixes as follows embodiment one with the nut card.
