Abstract
Description
Technical Field
[0001] This utility model relates to the field of proximal humeral fixation technology, specifically to an external fixation splint for convenient fixation of proximal humeral fractures. Background Technology
[0002] The humerus is the thickest bone in the upper limb. Its upper end forms the shoulder joint with the scapula, and its lower end forms the elbow joint with the radius and ulna. When the humerus is fractured, an external fixation plate is needed to fix the arm and prevent the arm from shaking and causing secondary injury.
[0003] However, existing external fixation splints cannot effectively adapt to the upper limb contours of patients of different body types, resulting in insecure fixation and easy displacement of fracture sites. Furthermore, splints are usually directly tied to the patient's arm, which may cause them to slip off after prolonged use. They are also not equipped with effective support structures and cannot be adjusted in real time according to changes in the patient's limb, thus limiting their clinical applicability. Utility Model Content

This allows the adjusting frame 3 to slide within the connecting cylinder 2, enabling fine-tuning of the protective plate 4. This allows for precise positioning of the support area based on the patient's arm length and fracture location, effectively adapting to the upper limb contours of patients with different body types.
[0017] Furthermore, the strap assembly 5 includes a first connecting strap 501 and a second connecting strap 502. One side of the first connecting strap 501 and the second connecting strap 502 are respectively fixedly connected to the upper part of the outer wall of the two protective plates 103.

[0020] Preferably, both slider 11 and slide 12 are T-shaped.
[0021] The working principle and usage of this utility model are as follows: Protective plate 101, protective plate 103, and protective plate 4 cover the proximal region of the humerus, providing external support and protection for the fracture site. Protective plate 101 is connected to protective plate 103 via connecting rope 102, forming a ring structure. Protective plate 4 is connected to the connecting cylinder 2 on the protective assembly 1 via an adjusting frame 3, used to support the injured area. The outer wall of the adjusting frame 3 is slidably connected to the inside of the connecting cylinder 2. By rotating the rotating rod 14 connected to the outside of the connecting cylinder 2, the gear 15 is driven to rotate, thereby adjusting the meshing rack 13, allowing the adjusting frame 3 to slide within the connecting cylinder 2. This enables fine-tuning and movement of the protective plate 4, thus achieving precise positioning of the support area according to the patient's arm length and fracture location. Effectively adapting to the upper limb contours of patients with different body types, the connecting strap 501 and connecting strap 502 are then slung diagonally over the shoulder. The Velcro loop 505 is then attached to the Velcro hook 504. With the setting of the connecting frame 503, the Velcro loop 505 can slide and adjust on its surface, thus achieving adaptability to patients of different body shapes and solving the problem of the protective plate easily slipping off after long-term wear. By pulling the telescopic rod 10, one end of it rotates on the fixed frame 9, and the other end of the telescopic rod 10 rotates in the middle of the slider 11, thereby enabling the slider 11 to slide on the inner wall of the slide groove 12. This allows the damping shaft 7 on one side of the support plate 8 to rotate inside the fixed sleeve 6, thereby enabling the support plate 8 to be angled and provide support for the patient's armpit at different angles.
