Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary medical devices, in particular to a cerebral blood vessel puncture and fixation device for neurointervention. Background Art

[0002] Neurointerventional surgery is a widely used method in the treatment of neurological diseases, in which cerebral vascular puncture is a key step. Cerebral vascular puncture is the insertion of a catheter into an intracranial blood vessel for interventional treatment or diagnosis. However, when performing this operation, a fixation device is required to ensure the firm position of the puncture catheter to prevent displacement or sliding, thereby reducing the risk to the patient and improving the success rate of the operation. Therefore, cerebral vascular puncture fixation devices for neurointervention came into being. This device is usually designed to safely and effectively fix the catheter on the intracranial blood vessels to ensure that the position of the puncture catheter is accurate and firm. The design of the fixation device must take into account the complexity of the intracranial anatomical structure and the special needs during the operation, such as the need to gently but firmly maintain the position of the catheter without damaging the surrounding tissue or blood vessel walls. The emergence of this device has greatly improved the safety and effectiveness of neurointerventional surgery and provided medical staff with a reliable tool, thereby improving the patient's treatment experience and the success rate of the operation.

[0003] After searching, the patent number "CN220385598U" mentioned in the text that "the utility model belongs to the field of medical equipment technology, and discloses a cerebral blood vessel puncture fixation device for neurointervention, including an arc-shaped plate, the arc-shaped plate is provided with a control slider and a locking piece, the outer wall of the arc-shaped plate is connected to a catheter channel, and a slidable fixing block is provided in the catheter channel. The fixing block located in the catheter channel can slide by sliding the control slider, so that the fixing block clamps and fixes the catheter, and the fixing block can be locked and fixed by the locking piece, so that the catheter can be clamped and fixed for a long time; the utility model solves the problem of poor catheter fixing effect in the prior art during cerebrovascular intervention surgery, "Suitable for catheter fixation during cerebrovascular interventional surgery", when in use, the fixing block located in the catheter channel can be slid by sliding the control slider, so that the fixing block clamps and fixes the catheter, and the fixing block can be locked and fixed by the locking piece, so that the catheter can be clamped and fixed for a long time, thereby improving the fixation effect. However, the above device only uses Velcro to perform a simple puncture fixation on the patient's thigh, and after the Velcro is attached to the patient's thigh, the puncture still requires the doctor to puncture the inside of the reserved hole of the device, which is easy to cause the puncture position to be wrong and thus cause medical accidents, and the Velcro is easy to fall off after being attached to the skin, and it is not easy to fix the puncture position.
