Controllable drug-liquid-ejecting thrombus clearing device

Abstract

The invention discloses a controllable drug-liquid-ejecting thrombus clearing device, and belongs to the technical field of medical instruments. The controllable drug-liquid-ejecting thrombus clearingdevice comprises a catheter, a recycling chamber, a drug liquid ejecting pipe, and a drug liquid reflecting mechanism; the drug liquid ejecting pipe penetrates through the interior of the catheter, and is used for ejecting drug liquid so as to break thrombus in a diseased blood vessel; the drug liquid reflecting mechanism is fixedly connected to the top end of the catheter, and is capable of reflecting the drug liquid ejected through the drug liquid ejecting pipe as well as controlling strength and area of the ejected drug liquid so as to protect the diseased blood vessel; and the recycling chamber penetrates through the front end of the catheter, and is fixedly connected with the front end of the catheter so as to be used for recycling broken thrombus and the ejected drug liquid as wellas preventing thrombus residues from flowing into other parts of the body. The controllable drug-liquid-ejecting thrombus clearing device is capable of ejecting the drug liquid under the premise of causing no vascular dissection so as to quickly break thrombus. Being used for treating thrombus, the controllable drug-liquid-ejecting thrombus clearing device is short in treatment time, capable of yielding faster results compared with conventional thrombolytic drugs; and the controllable drug-liquid-ejecting thrombus clearing device requires no subsequent long-term use of antithrombotic drugs compared with stent implantation treatment.

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...
