Abstract

The invention discloses a thrombus removal device with controllable medicinal liquid injection, which belongs to the technical field of medical instruments. The controllable liquid injection thrombus removal device includes a catheter, a recovery cavity, a liquid injection tube, and a liquid reflection mechanism; the liquid injection tube passes through the catheter, and is used to spray the liquid to crush the lesion thrombus on the blood vessel; the liquid reflection mechanism is fixedly connected to the top of the catheter, capable of reflecting the liquid sprayed by the liquid injection pipe, controlling the strength and area of ​​the sprayed liquid, and protecting the diseased blood vessel; the recovery The lumen passes through and is fixedly connected to the front end of the catheter, and is used for recovering crushed thrombus and sprayed medicinal liquid, so as to prevent residual thrombus from flowing into other parts of the body. The controllable liquid injection thrombus removal device can quickly crush the thrombus without causing blood vessel dissection by spraying the liquid medicine. Long-term use of antithrombotic drugs is not required.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a controllable medical liquid jet thrombus removal device. Background technique [0002] "Peripheral arterial disease" includes a variety of diseases that result in progressive narrowing or occlusion or aneurysmal dilation of the aorta and its noncoronary branch arteries, including carotid, upper, visceral, and lower extremity arterial branches. PAD is closely related to cardiovascular disease, and its severity is an indicator of the prognosis of cardiovascular risk. At present, the thrombus removal operation for PAD still faces great challenges, and thrombus removal is often required in patients with emergency interventional treatment. When performing thrombus removal operations on patients, personnel must grasp the precise rescue time, quickly orient the lesion location, save operation time, and remove thrombus from the body quickly and efficiently. blood vessels are n...
