Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a postoperative fixation device for a shoulder joint and an axilla assembled controllable pressure pad. Background Art

[0002] After orthopedic surgery, it is very important to use a fixation device to fix the surgical site. It can stabilize the surgical area and prevent the bone or joint from moving during the healing process, thereby promoting proper healing. In addition, using a fixation device to apply pressure to the surgical site can also help tissues, bones and joints heal faster, improve recovery results, and reduce and control postoperative swelling to prevent hematomas or fluid accumulation.

[0003] In the prior art, bandages are usually used for manual postoperative bandaging, but it is difficult to bandage and fix the wound at the joint, and the bandage is prone to fall off, resulting in exposure of the surgical site, which in turn affects the healing of the wound. In addition, during axillary lymph node dissection or axillary tumor resection surgery for breast cancer, a depression will be formed in the armpit. It is difficult to pressurize the surgical site in the armpit when using ordinary bandages for pressure bandaging, resulting in uneven force during bandaging, which affects the healing of the wound. The use of winding bandages is time-consuming and labor-intensive, and the patient's movement is restricted after being fixed, which reduces the patient's comfort. Chinese patent CN217853529U discloses a postoperative joint fixation device, including an arc-shaped upper support sheet, an arc-shaped lower support sheet, a swing structure connecting the upper support sheet and the lower support sheet, and a joint pad. The upper support sheet and the lower support sheet are fixed to the joint by bandages on the outside, thereby achieving fixation of the joint, but both use metal plates, which are easy to abrade the skin, and have limited movement and poor comfort.

[0004] Therefore, there is an urgent need to propose a modular fixation device that can perform pressure bandage on the shoulder joint. On the one hand, it can effectively solve the problem of pressure bandage on the armpit, and on the other hand, it can provide patients with a certain degree of comfort and mobility, while making postoperative pressure bandage more convenient and quick.
