Abstract
The utility model relates to a patella repositor which comprises a fixed jaw, adjusting nuts, sleeves, locking screws and a claw. The claw is composed of two parallel claw hooks. The two parallel claw hooks are connected through an arc-shaped rod. The fixed jaw is fixedly provided with the two parallel sleeves. The two sleeves are provided with the locking screws. Space between the two sleeves is identical with space of the two parallel claw hooks of the claw. Claw hook rods arranged on the top of the claw penetrate through the sleeves. The adjusting nuts are arranged on the claw hook rods arranged on at upper ends of the sleeves. The patella repositor is simple in structure, convenient to operate, suitable for all kinds of patella fractures, fixed, firm and not prone to dropping in patella positioning of fractures, and small in trauma compared with a surgery. When the patella repositor is used, aggregation force can be applied to a fracture end continuously, the patella repositor can be adjusted at random, fixed deviation can be corrected timely to keep relative constancy of fixed force, and fracture healing and functional training of knee joint can be carried out synchronously.
Description
Technical field:
This utility model relates to a kind of medical appurtenance, relates in particular to a kind of Patella repositor.
Background technology:
The common articular fracture of orthopaedics in medical science during Patella fracture, but because the powerful pulling force of quadriceps femoris often fixedly brings difficulty to reduction.Use at present the outer reduction fixture device treatment of bone Patella fracture that two kinds of methods comparatively commonly used are arranged, a kind of is respectively to advance a Kirschner wire with the two ends of fracture end, then pressurization, this pressurization of threading a needle is mainly that pressure is inadequate, and in early days in activity by the active force of quadriceps femoris and articulatio femoropatellaris, easily rotate forward displacement; Another kind is the two pairs of arc loopers of periphery insertion from patella, pressurize to the center, epiphysis is drawn close, thisly maintain static up and down by the arc looper, fixing position is on the cephalolateral margin of the utmost point up and down, can not can't use lower utmost point avulsion folding, lower utmost point comminuted fracture especially arbitrarily with folded block adjustment and the timely droop of correcting, limit its scope of application.
The utility model content:
The technical problems to be solved in the utility model is the above-mentioned deficiency for prior art, provides a kind of simple to operate, and is fixing reliable, the Patella repositor that result of use is good.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
A kind of Patella repositor comprises fixed claw, adjusting nut, sleeve, lock-screw and hook; Wherein, hook is comprised of two parallel grapples, is fixedly connected with by bow between two parallel grapples; Be fixedly installed two parallel sleeves on fixed claw, all be provided with lock-screw on two sleeves, spacing between two sleeves is identical with spacing between two parallel grapples of hook, and the grapple bar on hook top passes sleeve, is provided with adjusting nut on the grapple bar that is positioned at the sleeve upper end.
This utility model is simple in structure, easy to operate, be applicable to all types of Patella fracturies, to the patella location of fracture, fixed, difficult drop-off, wound is little with respect to operation, applies cohesion to fracture end sustainably during use, adjust arbitrarily, in time correct droop, to keep the relatively constant of bed knife, union of fracture and kneed functional exercise can synchronously be carried out.
Description of drawings:
The structural representation of Fig. 1 this utility model embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
A kind of Patella repositor of the present utility model comprises fixed claw 1, adjusting nut 2, sleeve 3, lock-screw 4 and hook 5.Hook 5 is comprised of two parallel grapples, is fixedly connected with by bow between two parallel grapples; Be fixedly installed two parallel sleeves 3 on fixed claw 1, all be provided with lock-screw 4 on two sleeves 3, spacing between two sleeves 3 is identical with spacing between two parallel grapples of hook 5, the grapple bar on hook 5 tops passes sleeve 3, is provided with adjusting nut 2 on the grapple bar that is positioned at sleeve 3 upper ends.During use, first fixed claw 1 is blocked the top edge of patella, then the hook 5 that will be positioned at sleeve 3 lower ends blocks the lower edge of patella, then tighten adjusting nut 2, the grapple 5 of lower end is moved upward, the patella of fracture is resetted, then tighten the lock-screw 4 on sleeve 3, prevent that hook 5 is loosening.
The above, it is only preferred embodiment of the present utility model, be not to be this utility model to be done the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
