Description

Technical Field

[0001] This utility model relates to the field of orthopedic medical technology, and more specifically to a steel plate that facilitates fixation of fractures of the greater tuberosity of the humerus. Background Technology

[0002] When a proximal humerus fracture occurs, it is sometimes necessary to fix multiple bone fragments together to ensure proper healing and restore correct function of the arm and shoulder. This fixation can be achieved by using screws or pins to secure a plate to the lateral side of the humerus adjacent to the humeral head.

[0003] A search revealed an existing patent (publication number: CN211460475U) that discloses a shaping and fixation plate for fractures of the greater tuberosity of the humerus. This plate offers a simple structure, is easy to shape, and after shaping, better matches the anatomical shape of the greater tuberosity, resulting in more secure fixation and less trauma to the patient. However, the inventors discovered the following problem with the existing technology during the development of this invention: the aforementioned fixation plate has a fixed width, requiring a larger incision to insert it into the injured area. This undoubtedly causes greater harm to the patient and prolongs recovery time.

[0004] In view of this, the present invention proposes a steel plate for facilitating fixation of fractures of the greater tuberosity of the humerus. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel plate that facilitates fixation of fractures of the greater tuberosity of the humerus, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a steel plate for facilitating fixation of fractures of the greater tuberosity of the humerus, comprising a steel plate body, the steel plate body being elongated and having a curved surface, a first fixing hole being provided on the surface of the steel plate body, connecting fixing parts being symmetrically arranged on the left and right sides of the steel plate body, and a traction adjustment part being provided between the steel plate body and the connecting fixing parts;

[0007] The connecting and fixing part includes an extension plate. The end of the extension plate away from the main body of the steel plate is arc-shaped. A second fixing hole is opened on the side of the extension plate away from the main body of the steel plate. The inner wall of the second fixing hole is provided with internal threads.

[0008] The traction adjustment unit includes a pin plate disposed on the side of the main body of the steel plate. An extension plate is provided with a telescopic groove on the side of the extension plate close to the main body of the steel plate. The pin plate is inserted into the telescopic groove, and a locking bolt is threadedly connected to the surface of the extension plate. A locking hole is provided on the surface of the pin plate for the locking bolt to be inserted.

[0009] As a further description of the above technical solution: there are several first fixing holes, and the several first fixing holes are arranged in a linear array at equal intervals on the surface of the steel plate body; by setting several first fixing holes, the first fixing holes can be adapted and selected according to the position and quantity requirements, and the use is flexible.

[0010] As a further description of the above technical solution: the nut surface of the locking bolt is provided with anti-slip texture, and the anti-slip texture corresponds to the surface position of the extension plate; by providing anti-slip texture, it is possible to prevent the locking bolt from loosening after the extension plate is locked with the locking bolt.

[0011] As a further description of the above technical solution: the number of locking holes is several, and the several locking holes are equally spaced in a linear array on the surface of the pin plate; by setting several locking holes, the position of the extension plate can be adapted and adjusted according to actual needs by inserting the locking bolt into the locking holes at different positions, and the adjustability is strong.

[0012] As a further description of the above technical solution: the pin plate and the main body of the steel plate are integrally formed, and the pin plate, the extension plate of the main body of the steel plate and the locking bolt are all made of titanium alloy; by using titanium alloy as the manufacturing material, the whole steel plate can have both strength and high corrosion resistance.

[0013] As a further description of the above technical solution: the thickness of the pin plate is 4 mm to 6 mm; because the thickness of the pin plate is 4 mm to 6 mm, it has a certain strength and toughness, and can be bent under external force according to actual needs, so as to facilitate fitting with the bone shape.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with existing technologies, this steel plate, which facilitates the fixation of fractures of the greater tuberosity of the humerus, involves fitting the main body of the steel plate to the humeral shaft, using medical screws inserted into the first fixation hole for adaptation and positioning, and then using medical screws inserted into the second fixation hole for adaptation and positioning between the extension plate and the greater tuberosity of the humerus. Finally, locking bolts are used to lock the extension plate in the locking hole, achieving the purpose of localized treatment of the fracture. When the entire steel plate structure is placed in the injured position, the extension plate can slide along the pin plate surface, maintaining a relatively small width during insertion. After insertion, the extension plate slides laterally along the pin plate, and the position of the second fixation hole is adjusted appropriately according to actual needs to accommodate fractures at the greater tuberosity of the humerus. In this case, the size of the incision during steel plate insertion can be reduced, shortening the subsequent recovery period for the patient.

[0016] 2. Compared with existing technologies, this steel plate for facilitating the fixation of fractures of the greater tuberosity of the humerus has several first fixation holes, which can be adapted to the position and number of holes as needed, making it flexible in use; the anti-slip texture prevents the locking bolts from loosening after the extension plate is locked; the multiple locking holes allow the position of the extension plate to be adjusted according to actual needs by inserting the locking bolts into the locking holes at different positions, providing strong adjustability; and the use of titanium alloy as the manufacturing material provides both strength and high corrosion resistance.
