Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a steel plate structure for the greater tubercle of the humerus. Background Technology

[0002] Proximal humeral fractures are a common type of upper limb fracture in adults, with fractures of the greater tuberosity being the most frequent. Because numerous muscles, including the subscapularis, supraspinatus, infraspinatus, and teres minor, attach to the greater tuberosity, the fractured bone fragment often shifts posterosuperiorly under the traction of these muscles. A bone plate is then needed to provide more stable and secure fixation to the bone fragment.

[0003] For patients with shoulder dislocation and greater tuberosity fracture of the humerus, the position of the greater tuberosity of the humerus is still unsatisfactory after reduction of the shoulder dislocation, requiring open reduction and internal fixation. Existing proximal humeral plates are long, requiring long incisions, thus causing significant trauma. Currently, there is no suitable greater tuberosity plate for the humerus. Furthermore, for fracture fragments of the greater tuberosity of the humerus, 3.5 locking nails can easily aggravate the comminutedness of the fracture fragments and cannot effectively fix the fracture fragments. Therefore, we propose a greater tuberosity plate structure for the humerus. Utility Model Content

[0004] The purpose of this invention is to provide a steel plate structure for the greater tuberosity of the humerus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel plate structure for the greater tuberosity of the humerus, comprising a plate body, wherein a first bendable member and a second bendable member are mounted side by side on the upper surface of the plate body, and a first locking pin hole is fixedly opened through the surface of both the first and second bendable members; three sets of suture holes are opened side by side on the upper surface of the plate body; a second locking pin hole and a third locking pin hole are opened through the surface of the plate body below the suture holes; a fourth locking pin hole is opened through the surface of the plate body below the second and third locking pin holes; and a fifth locking pin hole is opened through the surface of the plate body below the fourth locking pin hole.

[0006] Preferably, the diameter of the first locking hole is 2.7 mm.

[0007] Preferably, the diameter of the second locking hole is 3.5 mm.

[0008] Preferably, the diameter of the third locking hole is 3.5 mm.

[0009] Preferably, the diameter of the fourth locking hole is 3.5 mm.

[0010] Preferably, the diameter of the fifth locking hole is 3.5 mm.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This plate structure solves the problem that traditional proximal humeral plates, when used for fractures of the greater tuberosity of the humerus, often exacerbate the comminutedness of the fracture fragments and fail to effectively fix them. In contrast, the two first and second bendable components at the head end of this plate structure, along with the first locking screw hole, can effectively prevent the fracture fragments of the greater tuberosity of the humerus from moving upwards and effectively fix them.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 This utility model provides a technical solution: a steel plate structure for the greater tuberosity of the humerus, including a plate body 1. A first bendable component 2 and a second bendable component 3 are installed side by side on the upper surface of the plate body 1. A first locking hole 4 is fixedly opened through the surface of both the first bendable component 2 and the second bendable component 3. Three sets of suture holes 5 are opened side by side on the upper surface of the plate body 1. A second locking hole 6 and a third locking hole 7 are opened through the surface of the plate body 1 below the suture holes 5. A fourth locking hole 8 is opened through the surface of the plate body 1 below the second locking hole 6 and the third locking hole 7. A fifth locking hole 9 is opened through the surface of the plate body 1 below the fourth locking hole 8.

[0017] Specifically, the diameter of the first locking pin hole 4 is 2.7mm, the diameter of the second locking pin hole 6 is 3.5mm, the diameter of the third locking pin hole 7 is 3.5mm, the diameter of the fourth locking pin hole 8 is 3.5mm, and the diameter of the fifth locking pin hole 9 is 3.5mm.

[0018] In this embodiment, by installing two first bendable parts 2 and second bendable parts 3 at the head end of the plate 1, with first locking holes 4 through the surface of the parts, the fracture fragments of the greater tubercle of the humerus can be effectively prevented from moving upward and can be effectively fixed when fixing the greater tubercle of the humerus.

[0019] The shroud can be sutured and fixed by three suture holes 5 through the head end of the plate 1. The shroud is pulled down and passed through the suture holes in the corresponding directions and tied into knots. The shroud is pulled down and fixed to the steel plate in a parachute-like manner. This can effectively prevent the shroud from loosening, repair the shroud, and reduce the traction force of the shroud on the big tubercle.

[0020] The fourth locking hole 8 allows the plate 1 to be brought close to the bone cortex. The second locking hole 6 and the third locking hole 7 form a figure-eight fixation, creating triangular stability. The fifth locking hole 9 increases the pull-out resistance, thereby improving the performance of the plate 1.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
