Abstract
The utility model relates to an external fixer for humeral supracondylar fracture, which belongs to the technical field of medical equipment. The utility model is characterized in that the utility model is provided with a longitudinal arm and a transverse arm, wherein, the transverse arm is provided with a forearm rest and a pair of eagle beak pliers, and the longitudinal arm is provided with humerus screws and a universal joint. The connecting position between the longitudinal and the transverse arms can be adjusted. Compared with the prior art for treating humeral supracondylar fracture, the utility model has the advantage of simple operation, firm fixation, maintaining contraposition, etc., and the utility model can correct various moving modes of humeral supracondylar fracture.
Description
This utility model belongs to medical treatment product tool technical field, is a kind of supracondylar fracture of the humerus external fixator.
Supracondylar fracture of the humerus is a kind of common fracture disease, because the shape on the condyle of humerus is special, is offset flat shape, displacement fracture various informative, cripetura displacement, front and back displacement, lateral displacement, front and back angulation displacement, inside and outside one-tenth angle and rotation displacement etc. are arranged, existing rectification mode adopts manual reduction more, and plaster fixation can't be checked and be adjusted in agglutination, complicated operation, how can not reach ideal effect, complication such as about 50% generation cubitus varus cause lifelong disability.Part patient has to take operative treatment, performs the operation that then wound is big, and postoperative 70% to influence elbow joint stretch bend movable, even joint stiffness, lifelong disability.
The purpose of this utility model is that design is a kind of simple to operate, can correct various supracondylar fracture of the humerus displacement modes, fixedly secures the supracondylar fracture of the humerus external fixator of keeping para-position.
Technical solution adopted in the utility model is a kind of holder of design, and this holder has transverse arm and trailing arm, vertically offers forearm bracket and eagle's beak pliers groove along transverse arm, is arranged with the forearm holder in the forearm bracket, and cover does not have eagle's beak pliers in the eagle's beak pliers groove; Vertically offer the screw chute along trailing arm, be arranged with the humerus screw in the screw chute; Be connected by rotating connector between transverse arm and the trailing arm, rotating connector comprises connecting axle and adapter sleeve, and is provided with the positioning tooth component; Be provided with gimbal suspension below trailing arm screwing chute, gimbal suspension is provided with the positioning tooth component, thereby constitutes a kind of supracondylar fracture of the humerus external fixator.
Because this utility model taked technique scheme, compare with existing treatment supracondylar fracture of the humerus technology, have simple to operately, can correct various supracondylar fracture of the humerus displacement modes, fixedly secure, keep remarkable advantages such as para-position.
Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.
Accompanying drawing is represented general assembly structural representation of the present utility model.
As shown in the figure, the utlity model has transverse arm 2 and trailing arm 9, be connected by rotating connector 8 between transverse arm 2 and the trailing arm 9, rotating connector 8 comprises connecting axle and adapter sleeve, and adapter sleeve can slide along connecting axle, and adapter sleeve and trailing arm are connected, and adapter sleeve and horizontal buttocks are connected.Angle between transverse arm 2 and the trailing arm 9 can be adjusted.Rotating connector 8 is provided with meshing pad in location and meshing dish, can be with position between the arm and angle fix in length and breadth.At the far-end of transverse arm 2, vertically offer forearm bracket 10, in forearm bracket 10, be arranged with forearm holder 1.At the near-end of transverse arm 2, vertically offer eagle's beak pliers groove 3, in eagle's beak pliers groove 3, be arranged with eagle's beak pliers 4.In the upper end of trailing arm 9, vertically offer screw chute 6, be arranged with humerus screw 5 in the screw chute 6, in the lower end of trailing arm 9, be provided with gimbal suspension 7, gimbal suspension 7 is provided with the positioning tooth component.
During use:
1, under the local anaesthesia humerus screw 5 percutaneous are vertically revolved and follow closely in humerus epimere rear side, the nail WEILIAN connects in the screw chute 6 that is fixed in the holder trailing arm.
2, under the local anaesthesia with the olecroanon clamp on olecranon dorsal part cortical bone, pincers handle be fixed in the holder transverse arm eagle's beak pliers groove, forearm is laid in the forearm holder 1 that is fixed on the transverse arm.
3, correct displacement fracture:
(1) correct cripetura: holder arm in length and breadth is fixed in an angle of 90 degrees, makes under the traction to move on the humerus screw in the holder upper end, and cripetura is corrected, and screws screw tail end positioning tooth component and makes it to be fixed on the holder trailing arm.
(2) correct the front and back displacement: displacement forward or backward promotes the displacement round about in chute of eagle's beak pliers handle according to fracture, and the front and back displacement obtains and screws pincers handle nut after the elimination and be fixed on the transverse arm.
(3) correct lateral displacement: adapter sleeve can be passed about on the axle, and the connecting portion side is meshing dish, be meshed with its meshing pressure pad in outside, can about pass and drive the displacement of fracture far-end and correct lateral displacement.
(4) correct and to become the angle before and after the fracture: dwindle or increase arm angle in length and breadth to front or rear one-tenth angle according to fracture, become the angle before and after can correcting.Screw nut and make the meshing dish of meshing pad engagement transverse arm, fixing arm angle in length and breadth.
(5) correct inside and outside become angle and rotation: loosen that universal joint is adjusted to angle and rotation round about on the trailing arm, fracture reaches dissects after the para-position fixedly gimbal suspension.
4, post surgery treatment: (1) takes one week of antibiotic
(2) ethanol secondary every day is dripped in pincers nail hole
(3) the strap retainer out-of-bed activity recovers study in time
Handle complication
(4) remove the i.e. healing of external fixator fracture all around
