Make screw fixing more accurate and stable.

Description

A kind of lateral ankle universal locking bone plate

technical field

The utility model relates to a bone plate, in particular to a universal locking bone plate for the lateral malleolus.

Background technique

Ordinary bone plates are used in lateral malleolus surgery, especially for comminuted fractures of the distal fibula, fractures beyond the syndesmosis or comminuted osteoporotic fractures. The distal fractures are still difficult to meet the requirements of fixation. The existing anatomical bone plate or common locking plate does not have sliding holes for tibiofibular syndesmosis, and there are no screw holes that can be fixed at multiple angles at the distal end of the fibula. The screw holding force is low, which is easy to cause Internal fixation is not stable enough.

Contents of the invention

The purpose of the utility model is to provide a lateral malleolus universal locking bone plate which can change the positioning angle of the screw in view of the deficiencies in the prior art.

In order to realize the purpose of this utility model, adopt following technical scheme to realize:

A lateral malleolus universal locking bone plate, comprising a main board and a distal board connected to each other, the main board is provided with 2 to 8 screw holes, one side of the distal board is provided with a side board, and the distal The board is provided with 1-6 smooth fine holes and 3-6 locking holes b.

Preferably, the screw holes are 1-4 locking holes a and 1-4 locking pressure holes.

Preferably, the screw holes are 1-4 locking holes a, 1-2 ordinary holes and 0-2 locking and pressing sliding holes.

Preferably, the locking hole b is smaller than the locking hole a.

Preferably, the shape of the distal plate is matched with the anatomical arc of the distal head of the lateral malleolus.

Preferably, said distal plate is thinner than said main plate.

Preferably, 1 to 2 universal locking holes are provided on the side plate.

As a preference, the said universal locking hole is provided with a threaded concave block which can engage the screw end caps in different directions.

Compared with the prior art, the beneficial effect of the utility model is: use the equipped universal locking hole, cooperate with the design of a number of locking screw holes on the arc-shaped head, and prepare Kirschner wires for temporary fixation or suturing. The hole, in the lateral ankle fixation, can change the positioning angle of the screw, increase the holding force of the screw fixation, and make the screw fixation more accurate and stable.

Detailed ways

The specific embodiment of the present utility model will be described in detail below according to accompanying drawings 1-2.

Example 1

A lateral malleolus universal locking bone plate, comprising a main board 1 and a distal board 2 connected to each other, the main board 1 is provided with 4 locking holes a3 and 2 locking pressure holes 4, and the distal board 2 is provided with 3 smooth fine holes 10 and 3 locking holes b3-1. The shape of the distal plate 2 is matched with the anatomical arc of the distal end of the lateral malleolus, and the side plate 7 has a certain curvature. The anterior and posterior bicortical fixation of the distal fibula was used to prevent the screws from entering the articular surface of the distal fibula. The distal plate 2 is thinner than the main plate 1. For the smooth pores 10 on the distal plate 2 to temporarily fix and suture the peripheral soft tissue, a side plate 7 is arranged on one side of the distal plate 2, and a side plate 7 is arranged on the side plate 7 A universal locking hole 8 is provided, and the threaded concave block 9 above which can engage the screw end cap in different directions is used, so that the locking screw can be locked on the bone plate in different directions after the insertion of the fracture line. When in use, a bone plate of a suitable size is selected according to the patient's condition, and various screw holes 5 are matched.

Example 2

A universal locking bone plate for the lateral malleolus, comprising a main board 1 and a distal end board 2 connected to each other. The main board 1 has three locking holes a3, two common holes a11 and two locking and pressurizing sliding holes 6. The distal end The board 2 is provided with 5 smooth fine holes 10 and 4 locking holes b3-1. The shape of the distal plate 2 is matched with the anatomical arc of the distal end of the lateral malleolus, and the side plate 7 has a certain curvature. The anterior and posterior bicortical fixation of the distal fibula was used to prevent the screws from entering the articular surface of the distal fibula. The distal plate 2 is thinner than the main plate 1. For the smooth pores 10 on the distal plate 2 to temporarily fix and suture the peripheral soft tissue, one side of the distal plate 2 is provided with a side plate 7. Two universal locking holes 8 are provided, and the threaded concave blocks 9 above which can be engaged with screw tail caps in different directions are used, so that the locking screws can be locked on the bone plate in different directions according to the needs of the fracture line after being placed. When in use, a bone plate of a suitable size is selected according to the patient's condition, and various screw holes 5 are matched.
