Description

Rear ankle locking plate

Technical Field

The utility model belongs to the technical field of medical instrument and specifically relates to a back ankle lockplate.

Background

Ankle sprains are a common type of injury, and occur almost everyone throughout life. After the ankle joint is sprained, the force of a part of people is large, and the ankle joint fractures. Also, the posterior malleolus is affected by the Pilion fracture due to vertical violence such as falling from a high place. If the fracture involves the ankle joint, the ankle joint function can be lost if the fracture is not treated, and the life is seriously influenced.

At present, screw fixation is usually adopted clinically for Pilot fracture or ankle affected posterior ankle. However, some people have large fracture blocks of the rear ankle, and a few rear ankle steel plates can be selected. For ankle fracture patients who cannot be anatomically reset, the probability of ankle arthritis in the later stage is higher. Thus, strong fixation for the posterior ankle fracture is particularly important.

SUMMERY OF THE UTILITY MODEL

For solving the not enough of mentioning in the above-mentioned background art, the utility model aims to provide a back ankle lockplate, the utility model is used for solving the poor problem of back ankle fracture spiral shell locking stability, the lockplate is plate-type design, is down "T" shape, fixes the lockplate on the back ankle through the screw, improves the intensity and the stability of internal fixation after the internal fixation that resets of fracture.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a back ankle lockplate, includes the lockplate main part, its characterized in that, the lockplate main part includes the lockplate near-end, and the bottom of lockplate near-end is provided with the lockplate distal end, is provided with the changeover portion between lockplate near-end and the lockplate distal end, and a plurality of first fixed orificess have been seted up on the surface of lockplate near-end, and the second fixed orificess has been seted up on the surface of changeover portion, and a plurality of third fixed orificess have been seted up on the surface of lockplate distal end, and lock.

Furthermore, the locking plate proximal end, the locking plate distal end and the transition section are integrated into one piece, extend from the locking plate proximal end to the locking plate distal end, and are in an inverted T-shaped structure.

Furthermore, at least three first fixing holes are formed in the surface of the locking plate at the proximal end, and at least five third fixing holes are formed in the surface of the locking plate at the distal end.

Furthermore, the first fixing holes are distributed in a straight line shape, and the third fixing holes are distributed in a pyramid shape.

Furthermore, the first fixing hole, the second fixing hole and the third fixing hole are internally provided with internal threads.

Further, the locking plate main body is made of a titanium alloy material.

The utility model has the advantages that:

the utility model adopts the steel plate design, has high strength, is beneficial to the early functional exercise, shortens the postoperative recovery time, and has better fixation effect on the large posterior ankle fracture; the design of a hidden edge is adopted, so that the stimulation to soft tissues is reduced; the locking plate adopts the anatomical design, so that the anatomical reduction of the fracture is facilitated, and the steel plate does not need to be pre-bent in the operation; the steel plate fixes the far-end bone blocks by different longitudinal extension lengths to solve the problems of different sizes of rear ankle fracture blocks, and a plurality of screws are used for fixing the far-end bone blocks, so that the osteotomy fixation is more stable and firm; changes the current situation that the fixation of the front and back ankle fixing screws is unstable, and enlarges the adaptation disease range of the back ankle fracture operation. The design has wide application range, can be used for the surgical treatment of larger ankle bone blocks and is convenient for actual operation.
