Locking and pressurizing bone setting plate with slideable sliding blocks

Abstract

The invention discloses a locking and pressurizing bone setting plate with slideable sliding blocks. The locking and pressurizing bone setting plate with the slideable sliding blocks comprises a bone setting plate, wherein the two ends of the bone setting plate are arc-shaped, the bone setting plate comprises a bone setting plate upper part and a bone setting plate lower part which are sequentially connected, and the bone setting plate upper part and the bone setting plate lower part are connected in a smooth transition manner; the outer side surface, corresponding to a femoral shaft, of the bone setting plate upper part is provided with first locking holes, the bone setting plate upper part below the first locking holes is provided with a rectangular through hole, sliding blocks which can move along the inner wall of the through hole are arranged on the rectangular through hole, and the outer side surfaces, corresponding to the femoral shaft, of the centers of the sliding blocks are provided with screw holes; the bone setting plate lower part is provided with second locking holes. Through the arrangement, the locking and pressurizing bone setting plate with the slideable sliding blocks has the advantages that the influence of a bone setting device on periosteum blood supply can be reduced, the stripping range of the periosteum is reduced and the locking and pressurizing bone setting plate is applicable to various femoral shaft fracture situations; when the fracture does not heal well, screws on the top plate can be taken out, thus the sliding blocks can slide in a sliding groove when a patient bears partial load, pressure can be applied to fracture ends and the fracture healing is facilitated.

Description

technical field [0001] The present invention relates to an improvement of a bone-synthesizing device for treating femoral shaft fractures, in particular to a bone-synthesizing device that can pressurize the fracture during the healing process of the femoral shaft, reduce the fracture line, promote fracture healing, and reduce the impact of the bone-synthesizing device on the periosteal blood supply , Locking compression plate with slidable sliders to reduce the extent of periosteum dissection. Background technique [0002] At present, there are several types of bone plates used for internal fixation of fractures: 1. The disadvantage of ordinary bone plates is that the bone plate is a long metal block, and the holes on the bone plate are round holes, and the stability is maintained by friction with the bone surface after surgery. , the periosteum under the bone plate needs to be stripped during the operation, and the fracture end cannot be pressurized, which will easily lead ...

AI Technical Summary

Problems solved by technology

[0002]At present, there are several types of bone plates used for internal fixation of fractures: 1. The disadvantage of ordinary bone plates is that the bone plate is a long metal block, and the holes on the bone plate It is a round hole, and the stability is maintained by friction with the bone surface after surgery. During the operation, the periosteum under the bone plate needs to be stripped, and the fracture end cannot be pressurized, which will easily lead to bone resorption at the fracture end and affect fracture healing. It has been basically eliminated.

2. Ordinary compression bone plate, its characteristic is that there are round holes and pressure holes on the bone plate, which can realize the pressure on the fracture end, but the disadvantage is that the bone plate relies on friction with the bone surface to maintain stability after surgery, and it needs to be peeled off during the operation Subperiosteum under the bone plate, the fracture end can be pressurized during the operation, but it can no longer be pressurized after the operation, and it can also lead to bone resorption at the fracture end and affect fracture healing. It is still used routinely at present

3. Locking bone plate, which is characterized in that there is a circular keyhole on the bone plate, and the thread in the keyhole coincides with the thread at the tail of the screw, which has angular stability. It can be placed outside the periosteum during the operation, and there is no need to peel off the bone plate in a large area. The subperiosteum can protect the blood supply of the fracture end and facilitate fracture healing. Its disadvantage is that there is a circular keyhole on the bone plate, so the fracture end cannot be pressurized during and after the operation, and it can also lead to bone absorption at the fracture end and affect fracture healing. Mainly used for periarticular fractures and comminuted fractures
