Description

Bone holder with fixed steel plate

Technical Field

The utility model belongs to the field of medical equipment for fracture reduction, in particular to a bone holder with a fixed steel plate.

Background

The bone holder is a medical instrument commonly used by orthopaedics clinicians in fracture reduction temporary fixation, and has wide acceptance on reduction and holding stability of fracture ends, but the traditional bone holder fixes a steel plate and bones simultaneously, has poor conformity, worrys about the stability of fracture broken ends, needs to loosen the bone holder again after fracture reduction to put the steel plate, increases operation time, and has the risk of the fracture ends displacing again when the bone holder is loosened. The conventional bone holder has the following disadvantages: 1, the fracture end is fixed unstably, one side or two sides of the traditional two-claw or three-claw bone holder are fixed by a single point, the fixator is difficult to fix small bone blocks and irregular bone blocks and is easy to move for long oblique, spiral and butterfly unstable fractures; 2, the steel plate is easy to shift, and the steel plate is easy to slide or rotate because only one claw is fixed above the steel plate; 3, a steel plate needs to be placed for the second time, the traditional bone holders need to be loosened again to place the steel plate after the fracture is reset, in the process, operation steps are added firstly, the operation time is prolonged, and the risk of the fracture end moving again exists when the bone holders are loosened to place the steel plate; the bone holder, the skeleton and the steel plate can not be fixed into a whole, the displacement and the sliding are easy, the fracture fixation is not always effective, and the operation difficulty is increased.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bone holder of fixed steel sheet in area, includes the bone holder main part, the bone holder main part is provided with the clamping part, be provided with on the clamping part with locking steel sheet swing joint's fixed block, be provided with on the locking steel sheet with fixed block complex connecting portion.

As preferred, connecting portion are including cooperation groove and locking groove, the appearance and the fixed block phase-match in cooperation groove, the fixed block cover inserts the cooperation inslot, the appearance and the fixed block phase-match in locking groove, the fixed block cover inserts locking inslot, the cooperation groove with be equipped with the locking passageway between the locking groove, the fixed block makes it assemble with the fixed block more easily with the cooperation groove and the appearance matching of locking groove.

Preferably, the locking groove with the cooperation groove is adjacent to be set up and be in not same position on longitudinal direction, and during the assembly, the fixed block at first cooperatees with the cooperation groove, again with the locking groove cooperation, the height sets up makes the assembly relation more reasonable, reduces assembly error simultaneously.

Preferably, a fixing column is arranged between the fixing block and the clamping part, the width of the fixing column is smaller than that of the fixing block, two ends of the fixing column are fixedly connected with the fixing block and the clamping part respectively, and the width is reduced so as to clamp the fixing column, so that the fixing block is prevented from falling off.

Preferably, the locking channel is provided with a limit part matched with the fixing column, the width of the limit part is larger than that of the fixing column but smaller than that of the fixing block, and the purpose of reducing the width is to clamp the fixing column so as not to enable the fixing block to fall off.

Preferably, the clamping portion includes a first part and a second part, the first part and the second part are respectively located at two sides of the bone holder main body and are retracted or opened and closed relative to the bone holder main body, and a mode of clamping two ends simultaneously is adopted, so that stability is improved.

Preferably, the front end of the first part is provided with an inclination angle of 30 degrees with the vertical direction, the front end of the second part is provided with an inclination angle of 30 degrees with the vertical direction, and the smaller the angle is, the easier the bone is clamped with the front end, and the obstruction of the front end is reduced.
