Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a pressurized fixation device after cerebral vascular intervention. Background Art

[0002] Cerebrovascular interventional surgery usually uses special instruments. By selecting the right common carotid artery, left common carotid artery, aorta, etc., angiography results of the entire brain blood vessels are obtained, and then treatment is performed. After the cerebrovascular interventional surgery, a pressurized fixation device will be used to pressurize and fix the patient's legs. However, the existing pressurized fixation device still has certain defects when used.

[0003] Application number "CN202420085091.2" discloses a post-operative pressure fixation device for cerebral vascular intervention. This device, through an angle adjustment assembly, effectively solves the problem of existing pressure fixation devices being unable to adjust the clamping angle of the splint. The movable block within the angle adjustment assembly is movably connected to a rotating shaft and a threaded rod, respectively. The rotating shaft drives the movable plate to move via a threaded sleeve, and the movable plate drives the splint to rotate via a connecting rod, thereby achieving angle adjustment of the splint to accommodate different patients' legs and avoid affecting the pressure fixation effect due to the patient's thicker or thinner legs. The threaded rod can drive the splint to move via the movable block, so that the splint abuts against the patient's leg, thereby pressurizing and fixing the patient's leg. The provision of the angle adjustment assembly makes this device suitable for all patients, greatly increasing the practicality of the device. However, when the above solution is used, the splint lacks a movable structure, making it difficult for medical staff to adjust the position of the splint, making it inconvenient for patients of different heights to use. At the same time, the splint material is relatively hard, which can easily cause injury to the patient's legs. Utility Model Content
