Drainage device for internal carotid artery stripping

Abstract

The invention discloses a drainage device for an internal carotid artery stripping. With reasonable structural design of the device, two ends of the drainage device are blocked by air bags , so that adrainage pipe in an outer sleeve pipe can normally drain blood; and meanwhile, the device has a very good blocking effect, cannot cause blood leakage, and moreover, the operation is simple and convenient, the problem that tightness is difficult to master when a binding belt is used for adjusting is avoided; through reasonable structural design of a double-layer pipe, the air bags are formed between the double-layer pipes and are respectively formed at the front end and the tail end of the drainage pipe; in the use process, two ends of the pipe body are respectively connected to two ports of ablood vessel to be drained at first, and the air bags enter into the blood vessel, and then the air bags are inflated, after the air bags are inflated, the sealing between the air bags and the innerside wall of the blood vessel is realized, so that the two ends of the drainage device are blocked by the air bags, and the drainage pipe can normally drain blood, and meanwhile, the device has a verygood blocking effect, will not cause blood leakage; and moreover, the operation is simple and convenient, and the problem that the tightness is difficult to master when the binding belt is used for adjusting is avoided.

Description

technical field [0001] The invention belongs to the technical field of equipment used in the operation, and in particular relates to a drainage device for internal carotid artery stripping. Background technique [0002] The brain needs a blood supply to provide it with the nutrients it needs, and the carotid artery is one of the most important large blood vessels that carry blood from the heart to the brain. With age, arteriosclerosis, high-thickness and high-fat diet and other factors, carotid arteries will gradually form atherosclerotic plaques, resulting in carotid artery stenosis or even blockage, resulting in severe cerebral blood supply insufficiency. Severe carotid artery stenosis (>70% stenosis) is a high risk factor for severe cerebral infarction and requires surgical intervention. Therefore, carotid artery stenosis has become one of the killers that endanger people's health in today's society. [0003] According to NIS data in the United States, 151,129 cases ...

Problems solved by technology

[0007] In order to solve the problems existing in the prior art, the object of the present invention is to provide a drainage device for internal carotid artery stripping. Through reasonable structural design, the two ends of the drainage device are blocked by air bags to ensure The drainage tube can normally carry out blood drainage, and at the same time, it has a very good sealing effect, and will not cause blood leakage. Moreover, the operation is simple and convenient, avoiding the problem that the tightness is not easy to grasp when using a restraint belt to adjust
