Problems solved by technology

[0002] Fracture is one of the most common injuries. With the aging of the population, the annual incidence of fractures is gradually increasing. Fractures of the distal end of the fibula are common fractures. Kirschner wires, tension bands, screws, etc. lack strong fixation of the distal end of the fracture. , there is almost no specific bone plate for type B fractures, so it cannot fully meet the requirements of reduction and fixation
Although ordinary bone plates have a certain fixation strength, their conformability cannot be fully satisfied, and complications such as delayed skin healing are prone to occur. The existing anatomical bone plates or common locking bone plates do not have multi-angle fixation with screws, so that The screw is easy to loosen, the holding force is weakened, and the screw is easy to hit the articular surface, which makes clinical application difficult, affects the treatment effect, and brings pain to the patient, etc.

Embodiment Construction

[0014] The technical solution of the present invention will be described in detail below with reference to the drawings and specific embodiments.

[0015] Such as Figure 1 to Figure 2 As shown, the B-type fracture of the distal end of the fibula of the present invention embraces the bone plate, including a bone plate body, five universal locking screw holes 1, six locking screw holes 2, and four guide pin holes 3 are set on the bone plate body , where two locking screw holes are set at the front shank end of the bone plate body, and four locking screw holes are set at the back shank end. The front shank end of the bone plate body protrudes to both sides and is provided with an encircling wing 4, which can be used to encircle the encircling wing with the bone to increase the stability of the bone plate fixed to the bone body during use. The rear shank end of the bone plate body faces The side and rear are twisted, adopting a design that matches the fibula of the human body, w...

Abstract

The invention discloses an encircling bone bonding plate for a fibula distal-end B-type fracture. The encircling bone bonding plate comprises a bone plate body; multiple universal locking screw holes,multiple locking screw holes and multiple guide needle holes are formed in the bone plate body, the two sides of the front trunk end of the bone plate body are each provided with an encircling wing,and the back trunk end of the bone plate body is twisted in the laterally-rear direction; the universal locking screw holes of the bone plate body are formed in the different directions. A bone can beencircled by the encircling wings in cooperation with instruments, and the stability of a bone plate is improved; the attachment performance of the bone bonding plate matched with the fibula of the human body is better, and the influence on skin tension is smaller; through the universal locking screw holes in the bone bonding plate, locking screws can be fixed in multiple directions, articular surfaces can be avoided, and fixing strength is improved through crossed fixing.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to a B-type distal fibula fracture embracing bone plate used for reduction in fracture surgery. technical background [0002] Fracture is one of the most common injuries. With the aging of the population, the annual incidence of fractures is gradually increasing. Fractures of the distal end of the fibula are common fractures. Kirschner wires, tension bands, screws, etc. lack strong fixation of the distal end of the fracture. , and there is almost no specific bone plate for type B fractures, so it cannot fully meet the requirements of reduction and fixation. Although ordinary bone plates have a certain fixation strength, their conformability cannot be fully satisfied, and complications such as delayed skin healing are prone to occur. The existing anatomical bone plates or common locking bone plates do not have multi-angle fixation with screws, so that The screw is...
