Description

Bone plate structure

The present invention relates to a bone plate structure, and more particularly to a bone plate structure disposed on the tibia or femur.

When the sacral ball head or the femoral ball head is damaged or fractured, the current surgical methods are mostly fixed by the bone plate, and the ligament is sutured in the suture hole of the bone plate by the hook needle, and the bone is broken or fractured. Fill the damaged or fractured area.

However, in the actual operation, if the damage of the sacral ball head or the femoral ball head is too large, the sacral ball or the femoral ball head often has insufficient strength, so the traction force generated by the suture ligament tends to further damage the sacral ball head. Or the femoral ball head, therefore, it is impossible to perform bone plate fixation and aggregate filling at the same time, resulting in prolonged operation time.

Furthermore, the current suture hole of the bone plate is designed to penetrate the body of the bone plate straightly, so that the bone plate cannot be placed at a preset position, and then the hook hole is used to pass the suture hole for the ligament. The seam is solid, so it is not only easy to produce the deviation of the bone plate, but also increases the difficulty of the ligament.

Therefore, how to provide a brand-new bone plate structure design is nowadays The subject to be solved.

In order to solve the problems of the prior art and other problems, the present invention provides a new bone plate structure design for the tibia or femur.

The bone plate structure of the present invention comprises: a plate body fixed to the tibia or the femur, and having a first surface for contacting the tibia or femur, and a second surface opposite to the first surface; and a support body Attached to one end of the plate body for placement in a damaged portion of the humeral ball head, or for being placed in a damaged portion of the femoral ball head, thereby providing a supporting force for filling the sacral ball head with the aggregate The damage is filled or damaged at the break of the femoral head.

In an embodiment, the plate system of the bone plate structure of the present invention may have a suture hole extending obliquely through the plate body, and wherein the suture hole is formed at a boundary between the first surface and the second surface. a first opening and a second opening is formed on the second surface.

Compared with the prior art, the bone plate structure design of the present invention has the support body disposed at the end of the plate body, so that the support force can be provided in the damaged portion of the sacral ball head or the femoral ball head, thereby avoiding the problem in the prior art. There is not enough strength loss in the damaged sacral ball head or femoral ball head. Furthermore, since the bone plate structure of the present invention can have a suture hole obliquely penetrating the plate body, the plate body can be fixed at a preset position, and then the boundary between the first surface and the second surface can be utilized. The first opening is for the hook to pass through, so as to avoid the misalignment and the lack of sewing in the prior art.

The following content will be described in conjunction with the drawings, and the technical content of the present invention will be described by a specific embodiment. Those skilled in the art can easily understand other advantages and effects of the present invention by the contents disclosed in the present specification. This creation can also be implemented or applied by other different embodiments. The details of the present specification can also be modified and changed without departing from the spirit of the present invention. In particular, the proportional relationship and relative position of the various elements in the drawings are for exemplary purposes only and are not representative of actual implementation of the present invention.

Please refer to Figures 1 to 4 together to fully understand the structure of the bone plate structure itself and how it is applied to the tibia or femur.

In order to focus on the new bone plate structure of this case, the conventional components such as hooks, wires or screws, and related tissues such as muscles or ligaments, which are actually implemented, are not drawn in the drawing.

As shown in the figure, the novel design of the bone plate structure 1 provided in the present invention includes the plate body 10 and the support body 11.

The plate 10 is fixed to the tibia (or femur) 2 and has a first side for contacting the tibia (or femur) 2 and a second side opposite the first side. In an embodiment, the first The face and the second face may be curved faces; further, the first face for contacting the tibia (or femur) 2 may be further dependent on the curvature of the neck of the tibia (or femur) 2 of the specific subject. Designed to correspond to the humerus (or femur) 2 arc surface for subsequent fixation.

In one embodiment, the plate body 10 can have a slit hole extending obliquely through the plate body 10, and the suture hole can form a first opening 100b at a boundary between the first surface and the second surface, and The second face forms a second opening 100a. Specifically, since the first opening 100b is formed at the boundary between the first surface and the second surface, in actual implementation, the board 10 can be first set at a preset position and attached to the tibia. (or femur) 2, and then used to sew the ligament hook to use the first opening 100b to pass through the suture hole to complete the ligament sewn.

The plate body 10 can also have a fixing hole 101 extending straight through the plate body 10 for the passage of an associated fixing member (such as a screw) to lock the plate body 10 to the tibia (or femur) 2. In addition, a plurality of screw holes can be designed on the top of the fixing hole 101 for the screw 12 to be fixed obliquely to the femoral head or the humeral head, thereby improving the stability between the fracture blocks and giving moderate compression to help the bone healing; The figure is merely illustrative of three screw holes and three screws in an undefined number.

Furthermore, in an embodiment, the support body 11 may be composed of a plurality of dome-shaped sheets; or the support body 11 may be composed of a mesh bracket (not shown). As shown in the figure, the support body 11 composed of two scorpion-shaped sheets is arranged in the breakage 20 of the tibia (or femur) 2, and the ㄑ-shaped sheet can strengthen the structural strength of the damaged portion 20. Of course, the elastic support provided by the mesh support has a wider action surface than the illustrated snap-shaped body.

In addition, the support body 11 and the plate body 10 may be a structure that is movably connected or integrally formed. In the embodiment of the movable connection, the support body 11 and the plate body 10 can be connected by locking, snapping, snapping, and the like.

It is worth mentioning that, regardless of whether the support body 11 and the plate body 10 are designed to be movable or integrally formed, the support body 11 and the plate body 10 can be respectively designed to have various specifications, so as to be possible in actual implementation. Different situations that will be faced.

In order to shorten the time of postoperative recovery and to avoid the progress of the second operation, the support body 11 and the plate body 10 can be designed as a bioabsorbent structure.

In summary, since the bone plate structure design of the present invention has a support body disposed at the end of the plate body, it can provide a supporting force in the damage of the humeral ball head or the femoral ball head, thereby avoiding the problems in the prior art. There is not enough strength loss in the damaged sacral ball head or femoral ball head.

Furthermore, since the bone plate structure of the present invention can have a suture hole obliquely penetrating the plate body, the plate body can be fixed to the preset position of the tibia or the femur, and then the first side and the second side are used. The first opening at the junction allows the hooks and stitches to pass through, thereby avoiding the misalignment and the difficulty of sewing in the prior art.

The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify and change the above embodiments without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation should be as listed in the scope of patent application for this creation.
