Description of reference numerals: 1-plate main body, 2-connecting wing piece, 3-plate body connecting hole and 4-hole body step.

Detailed Description

The invention is further described with reference to the following specific drawings and examples.

As shown in fig. 1: in order to improve the fixed effect to the fracture end, enlarge accommodation, the utility model discloses a board main part 1 that can thermal deformation and a plurality of set up in plate body connecting hole 3 in the board main part 1, plate body connecting hole 3 link up board main part 1, by cold when hot, board main part 1 can contract and be the annular to make annular board main part 1 can encircle in the fracture end of bone.

Specifically, the plate main body 1 is made of a material meeting medical standards, the plate main body 1 is different in shape in different temperature states, wherein the plate main body 1 is in an open state in a cold temperature environment, the plate main body 1 is rectangular in shape, and when the plate main body 1 is changed from the cold temperature environment to a hot temperature environment, the plate main body 1 is in a contraction state, at the moment, the plate main body 1 contracts in an annular shape, so that the plate main body 1 can be encircled at a fracture end of a bone by utilizing the change of the annular shape after being heated. After the plate body 1 is tightly encircled at the fracture end of the bone, a fastening screw can pass through the plate body connecting hole 3 to be connected with the bone, so that the plate body 1 is further fixed with the bone.

In specific implementation, the plate body 1 includes a first body layer and a second body layer disposed on the first body layer, and the thermal expansion coefficient of the second body layer is different from that of the first body layer. When the plate body 1 surrounds the bone, the lower thermal expansion rate of the first body layer and the second body layer is in contact with the bone surface, and the higher thermal expansion rate of the first body layer and the second body layer is relatively far away from the bone surface. The embodiment of the utility model provides an in, board main part 1 is before not contacting with the bone, generally places in the lower liquid of temperature or environment, when needs encircle board main part 1 on the bone face, takes out board main part 1, when board main part 1 contacts with the bone face, because the temperature of bone face is higher, can make board main part 1 encircle immediately in the bone face of bone. Therefore, the plate body 1 can be effectively fixed under the condition that fragments exist in fracture through different shapes when the temperature is different, and the application range of fracture fixation is enlarged.

As shown in fig. 1 and 2, a plurality of evenly distributed connecting fins 2 are arranged on two sides of the plate body 1, the connecting fins 2 are symmetrically distributed on two sides of the plate body 1, the plate body connecting holes 3 are evenly distributed on the plate body 1 and the connecting fins 2, and the plate body connecting holes 3 on the connecting fins 2 are communicated with the connecting fins 2.

The embodiment of the utility model provides an in, connecting fin piece 2 outwards extends in the both sides of board main part 1, also sets up plate body connecting hole 3 at connecting fin piece 2, and plate body connecting hole 3 link up connecting fin piece 2. After a large number of plate body connecting holes 3 are arranged on the plate main body 1, corresponding plate body connecting holes 3 are selected according to actual requirements and fastening screws are placed in the corresponding plate body connecting holes 3. In specific implementation, the lengths of the connecting fins 2 on the two sides of the plate body 1 may be different, and may be specifically selected according to needs, which is not described herein again.

Further, the plate body connecting holes 3 are distributed in a row shape, and the plate body connecting holes 3 in the same row are mutually communicated. The embodiment of the utility model provides an in, plate body connecting hole 3 on board main part 1, the connection fin piece 2 can mutual independence, perhaps every row of plate body connecting hole 3 communicates each other, specifically can select as required to can be convenient with board main part 1 with the bone fixed can. In specific implementation, the hole wall of each plate body connecting hole 3 is provided with a thread, and a hole body step 4 is arranged in each plate body connecting hole 3, as shown in fig. 3. The screw thread and the hole step 4 can be conveniently matched with a fastening screw arranged in the plate body connecting hole 3, so that the reliability of fixing the plate main body 1 and the bone is improved.
