Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a head frame for monitoring cerebral blood flow during surgery. Background Art

[0002] Internal carotid artery stenosis and occlusion are one of the important causes of ischemic stroke, accounting for 10-15% of strokes.

[0003] Carotid endarterectomy (CEA) is the "gold standard" for the treatment of carotid stenosis and can significantly reduce the risk of ischemic stroke in patients with carotid stenosis. Studies on CEA in patients with carotid stenosis have shown that intraoperative carotid Doppler ultrasound (TCD) can monitor cerebral blood flow changes in real time, provide timely guidance for intraoperative operations and blood pressure control, and effectively reduce the risk of perioperative stroke.

[0004] Intraoperative TCD cerebral blood flow monitoring is to use a head frame to fix the TCD probe on the bilateral temporal region to avoid probe displacement during the entire operation and ensure that cerebral blood flow can be monitored in real time throughout the entire operation. At present, the head frame is mostly fixed at the forehead, top of the head and occipital point. However, in addition to TCD cerebral blood flow monitoring during the operation, the patient's anesthesia depth needs to be monitored by BIS to ensure the safety of the operation. BIS monitoring also requires the patch to be placed on the forehead. Due to the limited width of the forehead, the head frame will overlap with the BIS patch or even cover the patch. When fixing the head frame during the operation, the head frame needs to be tightened. At this time, if the BIS patch is located under the head frame, after the operation, the BIS patch will be close to or even press on the forehead skin for a long time, which often causes skin redness and swelling or even ulceration. Therefore, there is an urgent need for a head frame that can include monitoring functions and BIS patches to reduce complications such as skin damage during surgery.

[0005] In view of the above problems, the utility model provides a head frame for monitoring cerebral blood flow during surgery. Utility Model Content

[0015] Furthermore, the first side bracket and the second side bracket are arranged in a mirror image with each other.

[0016] Furthermore, the connecting belt includes a first belt and a second belt, the first belt is fixedly connected to the first side bracket, and the second belt is fixedly connected to the second side bracket.

[0017] Furthermore, Velcro is provided at the ends of the first and second straps, and the Velcro at the ends of the first and second straps can be contacted and fixed, and the tightness when worn by the patient can be adjusted to ensure that the straps are suitable for patients with different head sizes.

[0018] The beneficial effects of the utility model: the utility model has a reasonable structure; by arranging a receiving groove on the forehead part, the BIS patch can be embedded in the receiving groove, ensuring that the BIS patch will not press on the skin of the forehead, solving the problem of skin rupture caused by close contact with the skin, and reducing the problem of the head frame or BIS patch being unable to be placed due to insufficient forehead width during surgery, thereby ensuring the safety of the patient during the entire CEA operation.
