Abstract

The invention discloses a novel carotid endarterium stripping instrument. The instrument comprises two groups of stripping sub-bodies and tweezers arms, the right sides of the two groups of stripping sub-bodies are fixedly connected with the front and rear ends of the left sides of the tweezers arms, and a negative pressure assembly is fixedly mounted at the end part of the right side of each tweezers arm. According to the instrument, the forceps arms and the detacher bodies are arranged, so that the two sets of detacher bodies can be matched through the elasticity of the forceps arms to form a toothless forceps structure during use, and a doctor can operate the toothless forceps conveniently; when the detacher needs to be used, the forceps arms can be pressed forcefully to enable the two sets of detacher bodies to be attached, so that the device can be used as a stripper. Through the design, the device is simple in structure and can be used in combination with a stripper and toothless tweezers, the operation time is effectively shortened, and the operation efficiency is improved; and in addition, due to the dual-purpose design, the use cost can be saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel carotid endarterectomy device. Background technique [0002] Carotid endarterectomy is internationally recognized as the gold standard procedure for the prevention of ischemic stroke. During the operation, we need to block both ends of the carotid artery and strip off the lesion. During the operation, the carotid artery on the operation side cannot supply blood to the brain, and only the contralateral carotid artery supplies blood to the brain, so the length of operation time is particularly important. UI. The same is true for surgical operations. The shorter the operation time of carotid endarterectomy, the more it can reduce the time of cerebral hypoxia, and greatly reduce the risk during and after the operation. During the operation, after blocking the carotid artery, the operator needs to repeatedly exchange two instruments: stripper and toothless forceps; ...
