Description

Technical Field

[0001] The utility model relates to an improved steel plate for the proximal end of the humerus. Background Art

[0002] Currently, proximal humeral fractures are mostly fixed with a proximal humeral locking plate (philos). However, the distal end of the proximal humeral locking plate is long and plug-in-shaped. When using it, the deltoid muscle insertion point must be pushed aside first, and then fixed. If the deltoid muscle is not pushed aside, the plate cannot be placed and the fixation is not secure. However, stripping the deltoid muscle will cause the joint to sink after surgery, affecting postoperative functional recovery. Therefore, the deltoid muscle needs to be improved. At the same time, the proximal greater and lesser tuberosities are not fixed well and need to be improved and reinforced. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide an improved proximal humeral steel plate to solve the problems existing in the above technical solutions.

[0004] The present invention is implemented by the following scheme: a proximal humeral improved steel plate, comprising a steel plate, both ends of the plate body of the steel plate are arc-shaped surfaces, a proximal fixing hole group is opened on the arc-shaped surface of one end of the steel plate, and a distal fixing hole group is opened on the arc-shaped surface of the other end of the steel plate.

[0005] Furthermore, the left and right sides of the arc-shaped surface at one end of the proximal fixing hole group on the steel plate are arc-shaped, and the end side is arc-shaped, and the left and right sides and the end side are facing the bone side, and the left and right sides of the arc-shaped surface at one end of the distal fixing hole group on the steel plate are arc-shaped and facing the bone side.

[0006] Furthermore, the proximal fixing hole group includes two columns and three rows of proximal fixing holes.

[0007] Furthermore, the left and right sides of the arc surface at one end of the proximal fixing hole group on the steel plate extend symmetrically outward in an arc shape to form an arc-shaped wing plate, and at least one side wing fixing hole is vertically spaced apart on the arc-shaped wing plate.

[0008] Furthermore, the proximal fixing hole group bearing is provided with a plurality of mounting holes.

[0009] Furthermore, the distal fixing hole group includes a middle hole, and four sub-holes are evenly distributed on the periphery of the middle hole.

[0010] Furthermore, a long hole is opened in the middle of the steel plate body.

[0011] Furthermore, a middle hole group is arranged on the steel plate between the proximal fixing hole group and the long hole, and the middle hole group includes three middle holes, and the three middle holes are arranged in a triangular shape.

[0012] Compared with the prior art, the utility model has the following beneficial effects: reasonable design, shortened overall steel plate length, and the original plug-in plate-type distal end that needs to be inserted into the deltoid muscle for stripping is changed to an arc-shaped end plate. On the one hand, it better fits the bone situation, and on the other hand, the arc-shaped plate surface can be fixed through more distal fixing holes, which is more secure, without stripping the deltoid muscle, and the proximal large and small tubercles are firmly fixed.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] like Figure 1-3As shown, this embodiment provides an improved proximal humerus steel plate, including a steel plate 1, both ends of the steel plate body are arc-shaped surfaces, a proximal fixing hole group 5 is opened on the arc-shaped surface of one end of the steel plate, and a distal fixing hole group 6 is opened on the arc-shaped surface of the other end of the steel plate, one end of the proximal fixing hole group of the steel plate corresponds to the proximal end of the humerus, that is, the proximal arc-shaped surface 2, and one end of the distal fixing hole group of the steel plate corresponds to the distal end of the humerus, that is, the distal arc-shaped surface 3.

[0022] In this embodiment, in order to better adhere to the fracture, the left and right sides of the arc-shaped surface at one end of the proximal fixing hole group on the steel plate are arc-shaped, and the end side is arc-shaped, and the left and right sides and the end side are facing the bone side. The left and right sides of the arc-shaped surface at one end of the distal fixing hole group on the steel plate are arc-shaped and facing the bone side. The width of the arc-shaped surfaces at both ends is greater than the width of the middle part 4 of the plate body. The arc of the proximal end side is convenient for sticking to the top of the humerus, and the greater and lesser tuberosities are firmly fixed.

[0023] In this embodiment, the proximal fixation hole group includes two columns and three rows of proximal fixation holes 7, and the proximal fixation holes are opened on the arc surface close to the proximal end of the humerus.

[0024] In this embodiment, the left and right sides of the arc-shaped surface at one end of the proximal fixing hole group on the steel plate extend symmetrically outward in an arc shape to form an arc-shaped wing plate 14, and at least one side wing fixing hole 15 is vertically spaced apart on the arc-shaped wing plate. In this device, there are two side wing fixing holes, and the proximal end is further fixed through the side wing fixing holes to achieve multi-directional fixation.

[0025] In this embodiment, for the sake of reasonable design, the proximal fixing hole group bearing is provided with a plurality of mounting holes 8, and the diameter of the mounting holes is smaller than the diameter of the proximal fixing holes.

[0026] In this embodiment, the distal fixing hole group includes a central hole 9, and four sub-holes 10 are evenly distributed on the periphery of the central hole. The original plug-in plate-type distal end is changed to an arc-shaped plate surface, and the arc-shaped plate surface can be fixed in multiple angles through more distal fixing holes, so that the fixation is reliable.

[0027] In this embodiment, for the sake of reasonable design, a long hole 11 is opened in the middle of the steel plate.

[0028] In this embodiment, for reasonable design and further fixation, a middle hole group 12 is provided on the steel plate between the proximal fixation hole group and the long hole, and the middle hole group includes three middle holes 13, and the three middle holes are arranged in a triangular shape.

[0029] This embodiment has a reasonable design and shortens the overall length of the steel plate. The original plug-in plate-type distal end that needs to be inserted into the deltoid muscle stripping is changed to an arc-shaped end plate. On the one hand, it better fits the bone situation, and on the other hand, the arc-shaped plate surface can be fixed through more distal fixing holes, which is more secure and does not require deltoid muscle stripping.
