Stent thrombus taking device with thrombus capturing component

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a stent thrombus taking device with a thrombus capturing component. The stent thrombus taking device comprises a micro catheter, a micro guide wire is arranged in the micro catheter, a stent main body is installed at the top end of the micro guide wire, a contraction guide wire is arranged in the middle of the stent main body, a vibration wire is arranged at the top end of the stent main body, a signal block is arranged at the top of the vibration wire, a puncture drill bit is installed at the top end of the signal block, the capturing component is installed at the top end of the micro catheter, and a containing cabin is arranged in the capturing component. According to the stent thrombus taking device with the thrombus capturing component, thrombus can be effectively fixed through the stent main body and the contraction guide wire, the thrombus can be vibrated through the vibration wire to fall off from the blood vessel wall, electronic signals can be emitted in the thrombus taking work through the signal block so that a doctor can determine the position of the puncture drill bit at any time, the thrombus can be wholly taken out through the containing cabin and a closed air bag, and the capturing component can be bent according to the path of a blood vessel through a bendable hose.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a stent thrombus retriever with a thrombus capturing component. Background technique [0002] Ischemic stroke is a disease caused by narrowing or occlusion of the arteries supplying blood to the brain, which can lead to necrosis of brain tissue. After the occurrence, the blood vessels need to be recanalized in the shortest possible time. Clinically, there are two main methods of treatment for ischemic stroke caused by thrombus, namely drug thrombolysis and mechanical thrombectomy. As a new type of thrombus therapy, mechanical thrombectomy is especially suitable for patients with unsatisfactory thrombolytic effect or who are not suitable for thrombolytic therapy. [0003] When the original stent retriever is used, the position of the thrombus retriever and the thrombus is usually determined by the image generated by the medical fluoroscopy instrument. However,...

Problems solved by technology

[0003] When the original stent retriever is used, the position of the thrombus retriever and the thrombus is usually determined by the image generated by the medical fluoroscopy instrument. However, during the thrombus removal process, the doctor cannot judge the position of the drill bit well because the drill bit will overlap with the thrombus. position, which hinders the thrombus removal work, and when the thrombus is fixed and removed by the stent, some thrombus may be left in the blood vessel, resulting in incomplete treatment and hidden dangers to the patient's future health
