Abstract
The utility model discloses a shape memory bone plate under axial pressure, which is characterized in that: one or two ends of the bone plate are provided with a deformation hole, the lateral of the deformation hole is provided with a screw hole. Adding axial pressure and bone nonunion are the difficult problems of orthopedic operation, which attracts the attention of world medical field. The utility model axial pressure bone plate provides a new selection method for the bone nonunion. The utility model is fit for connecting fracture site in orthopedic operation, and has the unique advantage of regulative continuous and dynamic axial pressure, provides a good creation environment for fracture healing.
Description
Technical field:
This utility model relates to technical field of medical, and a kind of specifically employing Ti-Ni marmem material is made, the shape memory axial pressure blade plate of the internal fixation that is used to fracture.
Background technology:
" AO " the serial orthopedic fixation device that generally adopts obtains penetration and promotion at home in the world, and the limitation of " AO " series also day by day manifests clinically.As pressurized bone plate, when operation can be disposable passive to the fracture end pressurization, in case the infiltration rate of healing stage fracture line greater than bone formation rate inside and outside the film, then compression steel plate has become general steel plate, the forfeiture pressurization causes bone does not connect to connect the generation of disease.
Summary of the invention:
The purpose of this utility model is to provide a kind of blade plate of energy axial pressure, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is: shape memory axial pressure blade plate, it mainly comprises a blade plate, it is characterized in that: an end or two ends at blade plate are provided with the distortion hole, and the outside in distortion hole is provided with screw hole.
It is a difficult problem in the bone surgery that axial pressure and bone does not connect connect disease, by world medical circle is paid close attention to, this utility model shape memory axial pressure blade plate provides brand-new system of selection for bone does not connect connects disease, make fracture site when it is suitable for bone surgery and connect usefulness, unique superiority with regulatable lasting dynamic axial pressurization is for the healing of fracturing provides good build environment.

The utility model will be further described below in conjunction with drawings and Examples.
This utility model mainly comprises a blade plate 1, it is different from prior art and is: an end or two ends at blade plate 1 are provided with distortion hole 2, the blade plate 1 that adopts the Ti-Ni marmem material to make in force, distortion hole 2 deformables of its one or both ends, the outside in hole are provided with screw hole 3 (non-distortion hole).Utilize the memory effect of memorial alloy, the shape that changes the hole in the time of＜5 degrees centigrade can make the screw in the outside outwards extend, and screws in screw this moment, is heating up＞37 degrees centigrade the time, distortion hole 2 restore can make screw in key screw along the axle center to the displacement of the center of blade plate 1, i.e. axial pressure.This moment, the screw on blade plate 1 should be simultaneously to the center displacement, and slotted hole 4 has been reserved the space for the screw displacement.
