Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a postoperative fixation device for a controllable pressure pad that can be assembled with the shoulder joint and axilla. Background Technology

[0002] After orthopedic surgery, immobilizing the surgical site with a fixation device is a crucial step. This stabilizes the surgical area, prevents bone or joint movement during the healing process, and promotes proper healing. Furthermore, applying pressure to the surgical site with a fixation device helps tissues, bones, and joints heal faster, improving recovery; it also reduces and controls postoperative swelling, preventing hematomas or fluid accumulation.

[0003] Existing technologies typically use bandages for manual postoperative dressing. However, bandaging and securing wounds at joints is difficult, and the bandages are prone to slipping off, leading to exposure of the surgical site and hindering wound healing. Furthermore, in breast cancer surgeries involving axillary lymph node dissection or axillary tumor resection, a depression forms in the armpit. Using ordinary bandages for pressure dressing makes it difficult to apply pressure to the surgical site, resulting in uneven force and affecting wound healing. Wrap-around bandages are time-consuming and labor-intensive, and restrict patient movement after fixation, reducing patient comfort. Chinese patent CN217853529U discloses a postoperative joint fixation device, including an arc-shaped upper support, an arc-shaped lower support, a swinging structure connecting the upper and lower supports, and a joint pad. The upper and lower supports are externally fixed to the joint with bandages, achieving joint fixation. However, all of these devices use metal plates, which can easily chafe the skin, restrict movement, and result in poor comfort.

[0004] Therefore, there is an urgent need to develop a modular fixation device that can apply pressure bandages to the shoulder joint. This device would effectively solve the problem of applying pressure bandages to the armpit, while also providing patients with a certain degree of comfort and mobility, and making postoperative pressure bandaging more convenient and faster.

[0014] Furthermore, the shoulder fixing strap has a first recess and a second recess on both sides of the middle section, and the diameter of the first recess is larger than the diameter of the second recess to fit the curve of the armpit and shoulder joint.

[0015] Furthermore, both the first and second fasteners are bolt assemblies, and the bolt assembly includes a bolt and a nut.

[0016] Furthermore, the connector is made of elastic rubber, which facilitates shoulder joint movement.

[0017] Furthermore, the inner ends of the upper arm fixing strap and the shoulder fixing strap are provided with nylon hook and loop fasteners, and the outer ends are provided with nylon hook and loop fasteners, which are connected in conjunction with each other.
