Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical instruments, and in particular to a straight pen type intraoperative sensor for vascular tinnitus. Background Art
[0002] Vascular tinnitus is also called pulsatile tinnitus. Patients can hear the pulsating sound of blood flowing in their own arteries, which is synchronized with the heartbeat. In most cases, it is unilateral, and the tinnitus disappears or is significantly reduced when the ipsilateral carotid artery is pressed. Tinnitus can also be reduced when lying on the side (which side to lie on varies from person to person).
[0003] One of the main causes of vascular tinnitus is the damage of the bone wall on the surface of the blood vessels behind the ear (sigmoid sinus bone wall defect); surgical treatment is used clinically, and the defect in the sigmoid sinus bone wall needs to be repaired.
[0004] However, currently, sigmoid sinus bone wall defects are observed under a microscope, which makes it difficult to accurately determine whether vascular tinnitus disappears during surgery and the specific corresponding location of the sigmoid sinus bone wall defect. In addition, it is impossible to check whether there are other bone wall defects missed in the sigmoid sinus bone wall after the bone wall is repaired.
