Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

The contact area between the bone contact surface and the bone surface of the existing humerus distal end bone fracture plate is too large, so that blood circulation is easily affected, and the recovery of a patient becomes slow.

In order to solve the technical problem, the technical scheme of the application takes the influence of the bone fracture plate on blood circulation reduction as a starting point, and under the premise that the strength of the bone fracture plate is not influenced basically, the effect of reducing the contact area between the bone contact surface and the bone surface can be realized by arranging a surface contact lightening structure on the first combining hole and the second combining hole, so that the blood circulation of a patient is good, and the recovery speed of the patient is accelerated.

The present invention will be further explained with reference to the drawings and specific embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides a distal humeral bone plate for reducing bone plate contact, including a bone plate body having a stem portion 1 and a head portion 2 integrally connected to each other, the stem portion 1 having a first coupling hole 3 and a plurality of second coupling holes 4 located at both sides of the first coupling hole 3, the head portion 2 having a hook plate portion 5 at one side thereof, the hook plate portion 5 and the head portion 2 each having a plurality of locking holes 6; the distal humerus bone fracture plate is of a bone-imitating structure matched with a corresponding bone, and is particularly divided into a stem part 1, a head part 2 and a hook plate part 5, and the first combining hole 3, the second combining hole 4 and the locking hole 6 are used for connecting screws for fixation.

The utility model provides a reduce humerus distal end coaptation board of bone plate contact, the coaptation board body can have the bone contact surface, first combination hole 3 and second combination hole 4 all are equipped with face contact and alleviate structure 7 in the one end of bone contact surface, and face contact alleviates structure 7 and is used for reducing the area of contact of bone contact surface and bone surface.

So, the bone contact surface of humerus distal end coaptation board alleviates structure 7 through the face contact and can make its and the area of contact greatly reduced of bone surface, has reduced the influence to the blood circulation for patient recovery speed is faster, and sets up face contact through combining hole 3 and second and alleviate the combination, can reduce the influence that this structure setting was to coaptation board intensity, and structural design is more reasonable.

In one embodiment, the surface contact mitigation structure 7 is formed by reaming the first and

second coupling holes

3 and 4 at their ends adjacent to the bone contact surface.

It is also understood that the surface contact mitigation structure 7 is formed by a chamfer, and the chamfer structure can be a cambered surface or a straight surface, without limitation. Therefore, the contact area between the bone contact surface and the bone surface can be reduced, and the purpose of reducing the influence on blood circulation is achieved.

Further, the first and

second coupling holes

3 and 4 have a size larger at one end adjacent to the bone contact surface than at the other end. Therefore, the contact area between the bone contact surface and the bone surface can be reduced, and the purpose of reducing the influence on blood circulation is achieved.

Specifically, the cross section of the surface contact reducing structure 7 is a slope structure. The inclined plane structure can be an inclined plane of 30 degrees, so that blood transportation can be better facilitated, and the structure is more reasonable.

In an embodiment of the application, the bone plate body is made of steel material.

Specifically, the size of the first coupling hole 3 is larger than that of the second coupling hole 4.
