It is equipped with fovea superior slot, the lower wing, lower silicagel pad center bottom are equipped with recessed slot.
Further, it is equipped with spring on the right side of the rotational pin, the spring top is fixedly connected with lower wing, the spring
Bottom end is fixedly connected with upper wing.
Further, the opposite side of the upper wing, lower wing right end is equipped with handle.
Further, one layer of rubber sleeve is cased on two handles.
The utility model has the beneficial effect that compared with prior art
1, upside wing is in arc-shaped, can effectively be bonded kneecap outer surface, and lower silicagel pad can effectively be bonded kneecap cartilage, on
Locking teeth, the connection of lower locking tooth engagement, convenient for locking after holding, recess hole is convenient for Kirschner wire insertion；
2, by the elastic force of spring can further clamping device, make its be bonded kneecap；Handle holds convenient for medical staff,
Rubber sleeve can increase frictional force；The apparatus structure is simple, easy to use, exerts a force when clamping kneecap to be " face-to-face ", can be effective
Damage when device resets to kneecap is reduced, locking teeth effectively fixed reset kneecap, otch can facilitate Kirschner wire temporarily to set
Enter, broken bone block displacement may when during reduction Kirschner wire fixation.
