Carotid endarterectomy suction head

Abstract

The invention relates to a carotid endarterectomy suction head. The carotid endarterectomy suction head is characterized by comprising a rectangular flaky structural body, a collection chamber is formed at the bottom of the flakey structural body, a plurality of 7-shaped suction tubes are arranged in the upper portion of the flaky structural body, one end of each suction tube is communicated with the collection chamber, and the other ends of the suction tubes are suction side holes located at the edges of two sides of the flaky structural body; the collection chamber is further connected with a suction apparatus connector outside the flaky structural body. The carotid endarterectomy suction head is applied for continuously sucking exudation in the process of carotid endarterectomy, other suction tubes can also continue working even though several suction tubes are blocked, risks that suction causes injuries to vascular walls and peripheral important nerve and blood vessels are effectively avoided, obstacles to a surgery operator due to the fact that an assistant holds traditional suction tubes in hands in operation are reduced, and suction efficiency and surgical field exposure effect are improved obviously; by the adoption of the carotid endarterectomy suction head, working efficiency during open surgery can be obviously improved, surgery time is reduced, and injuries to the vascular walls and peripheral important nerve and blood vessels are decreased.

Description

Technical field [0001] The invention relates to a medical device, in particular to a suction head for carotid endarterectomy, which is used in the process of internal carotid artery endarterectomy to continuously attract blood to keep the operation field clear. Background technique [0002] Cerebrovascular disease ranks the third cause of death in humans, and more than 2 million people die from stroke each year. Regardless of different regions of the world or different races, cerebrovascular accidents are the main cause of death and disability. In my country, there are 1.2 million to 1.5 million new patients with complete stroke each year, and 800,000 to 1 million deaths. About 75% of the survivors are disabled, and the recurrence rate is as high as 41% within 5 years. In the United States, 500,000 people get sick every year, of which 150,000 die. Among the survivors, more than 2 million require medical attention. Cerebrovascular diseases are a serious threat to human life and ...
