Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a pressurizable arm bone fixation device. Background Art

[0002] Postoperative fixation is an important part of the treatment of arm surgery or other upper limb trauma. Traditional postoperative fixation methods, such as the use of hard materials such as plaster or metal brackets, can provide the necessary support, but often lack flexibility and comfort. These materials are not easy to adjust, and the pressure cannot be adjusted according to the patient's specific recovery situation, which may cause discomfort to the patient or restrict blood circulation. In particular, limbs are prone to swelling after surgery, and pressure bandaging is required to reduce swelling. Traditional pressure bandaging methods usually use cotton pads, but this method is easy to fall off, and it is inconvenient to operate, has poor convenience, and is not easy to adjust the position. Especially when using traditional cotton pads for pressure bandaging, due to different techniques, uneven pressure may occur, which can easily cause skin pressure sores at bony landmarks such as the ulna. These problems highlight the lack of adaptability of existing postoperative fixation techniques.

[0003] In recent years, with the development of material science and intelligent technology, some innovative postoperative fixation devices have begun to appear. These devices try to use softer materials that are more adaptable to the patient's body shape, and integrate sensors and intelligent control systems to achieve more precise pressure control and monitoring. For example, an orthopedic arm surgical fixation device includes a lighting component and an arm support fixation component. The arm support fixation component is arranged above the lighting component. The adjustable multi-segment lighting component can perfectly match the lighting of the doctor during surgery. The arm support fixation component can be set to adapt when the patient places his arm on the device. It can quickly adjust to the state that best suits the patient's arm placement according to the shape of the patient's arm, greatly improving the comfort of the patient's arm during fixation.

[0004] In addition, there is also a temporary arm fixation device during surgery and a postoperative shaping device, including a liquid storage box, a thermoplastic splint cover, and a height adjustment cover. During surgery, the height of the height adjustment cover can be adjusted through the height adjustment component to effectively fix the affected limb and place the affected limb and arm during surgery, making it easier for doctors to perform surgery, streamlining the number of surgical operators, and reducing surgery time. After surgery, due to the thermoplastic splint cover, the splint cover can be heated by a heating device to perform personalized shaping according to the patient's own conditions.

[0005] Therefore, it is urgent to develop a fixation device that can provide stable support and adapt to changes in arm swelling, while also having good adjustability and comfort, which is an urgent problem to be solved in the current postoperative fixation technology field. Moreover, this device should be able to be flexibly adjusted according to the patient's recovery progress to adapt to the physiological changes of the patient's arm, while reducing the patient's discomfort and improving the convenience of treatment.
