Detailed Description
The following describes specific embodiments of the present utility model in detail with reference to the drawings.
According to an embodiment of the present utility model, there is provided a fixation plate for fixing a simple fracture of a metacarpal base. Wherein fig. 1-3 show one specific embodiment.
Referring to fig. 1 to 3, the fixing plate for fixing the simple fracture of the metacarpal base comprises a plate body 1, a middle section 2 and a flank section 3, wherein the plate body 1 is provided with a radian to form a curved surface for fitting a bone surface; one end of the plate body 1 is provided with a screw hole 4, and the other end is provided with the middle section 2; the middle section 2 is L-shaped, one end of the middle section is connected with the plate body part 1, the other end of the middle section extends downwards in a tilting way, and the end part of the middle section is sharp; the flank section 3 is arranged on the same side as the middle section 2, is provided with two flank sections and is respectively arranged on two sides of the middle section 2; the flank section 3 is C-shaped, and can better wrap the palm bone. One end of the flank section 3 is connected to the plate body 1, the other end is curled inwards and the end of the end is sharp.
The working process of the fixing plate can be summarized as follows: according to the conventional operation mode, the metacarpal fracture end is subjected to anatomical reduction and temporary fixation, then the flank section 3 is attached to the metacarpal head to wrap, the position of the middle section 2 is determined, after the hole is rotated, the flank section 3 wraps the metacarpal head, the middle section 2 is inserted into the pre-drilled hole, then the plate body 1 is subjected to radian shaping according to the metacarpal body anatomical structures of different patients, and the flank section 3 and the middle section 2 are adjusted to stably wrap the bone. After the plate body part 1 is attached to the bone surface, a screw is implanted into a preset screw hole 4 according to actual conditions, so that the fixation of the simple fracture of the metacarpal base part is realized.
Through above-mentioned technical scheme, this fixed plate can effectively laminate the metacarpal to provide good fixed environment, make the patient can progressively carry out hand function exercise after the operation, help the patient to resume health.
In one embodiment provided by the present disclosure, the other end of the middle section 2 is inclined at an angle of 70 ° to 100 °. This allows the sharp end of the intermediate section 2 to be fixed to the metacarpal head, thereby replacing the implant screw. Therefore, the total weight of the implant is reduced by using the nail plate system for the fixing plate relative to the common metacarpal, the wound area can be reduced, and the stability of the metacarpal fixing effect can be ensured.
Alternatively, the inclination angle of the middle section 2 is approximately 90 degrees, and the bending part is in arc transition, so that stress concentration can be prevented, and a better fixing effect on the metacarpal bone can be achieved. Of course, it is also possible to form 70 °, 80 ° or 100 °, which can be flexibly arranged according to the metacarpal bone conditions.
In the present disclosure, the radian of the plate body 1 is 20 ° to 50 °. By such design, the plate body 1 can be further shaped to be more attached to the bone surface. Alternatively, the curvature of the plate body 1 is 25 °. Alternatively, the curvature of the plate body 1 may be set to 20 °, 30 °, 40 ° or 50 °, and may be flexibly set by those skilled in the art according to actual needs.
In the present disclosure, the extension length of the middle section 2 is shorter than that of the side wing section 3, so that the implant can be conveniently fixed on the metacarpal bone, and screws can be effectively replaced by the design of the middle section 2 and the side wing section 3, so that the total amount of the implant is reduced, the wound area is reduced, and the later rehabilitation of a patient is facilitated.
In an embodiment provided by the disclosure, the plate body 1, the middle section 2 and the side wing sections 3 are integrally formed, which is beneficial to ensuring the connection strength between the plate body and the side wing sections, reducing the shape and position deviation, facilitating the operation in surgery and also facilitating the product forming and manufacturing.
In the present disclosure, the two sides of the plate body 1 are concave inwards, so that the plate body can better fit the metacarpal anatomy structure, and can provide a good supporting environment for the metacarpal fracture.
In one embodiment provided by the present disclosure, the edge profile of the plate body 1 is formed into an arc shape, which can facilitate the shaping of the plate body 1 by an operator, reduce the blunting resistance, and further make the plate body 1 better fit to the metacarpal bone.
In the present disclosure, the plate body 1, the middle section 2 and the side wing sections 3 are made of titanium alloy. Thus, the resulting fixation plate has the following advantages as an implant prosthesis: the strength is high, the chemical stability and the biocompatibility are good; no toxicity and no harm to human body; the elastic modulus is low and is more matched with the human skeleton; the memory alloy has elastic capability and shape recovery function.
In the present disclosure, the screw holes 4 are provided in two spaced apart positions. In this way, the operator can selectively implant 1 or 2 screws according to the condition of the patient's metacarpal bone, thereby fixing the fixation plate to the metacarpal bone.
The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present utility model within the scope of the technical concept of the present utility model, and all the simple modifications belong to the protection scope of the present utility model.
