Problems solved by technology

[0005] The treatment of arterial occlusive diseases of the lower extremities has always been difficult, especially for the treatment of occluded blood vessels. The traditional treatment method is usually to use a guide wire alone to open it. When the lesion occurs, due to insufficient support, the head end is prone to discount, bending, twisting, etc., resulting in treatment failure

Embodiment Construction

[0034] In order to better illustrate the purpose, technical solutions and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] An embodiment of the intravascular support catheter with a rotary cutting tip of the present invention, the structural schematic diagram of the intravascular support catheter with a rotary cutting tip in this embodiment is as follows figure 1 , figure 2 Shown:

[0036]It includes a joint 3, a tube body 2, and a rotary cutting tip 1. The rotary cutting tip 1 is provided with a rotary cutting metal knife 8, and the metal knife 8 is partially embedded in the rotary cutting tip 1. The cutting edge 9 of the metal knife is exposed outside the rotary cutting tip. 8 is visible under X-ray; the length of the metal knife 8 embedded in the rotary cutting tip 1 is 3-8 mm, the thickness of the metal knife 8 is 0.05-0.15 mm, and the length of the ...

Abstract

The invention discloses an intravascular support catheter with a rotary-cutting tip. The support catheter comprises a connector, a catheter body and the rotary-cutting tip; the rotary-cutting tip is provided with a rotary-cutting metal tool, the metal tool is partially embedded in the rotary-cutting tip, the cutting edge of the metal tool is exposed to the outer side of the rotary-cutting tip, andthe metal tool is visible under X rays. The intravascular support catheter with the rotary-cutting tip can assist and support a guide wire in unblocking the vascular lesion; meanwhile, the catheter can achieve the functions of exchanging of guide wires, perfusion and the like. The support catheter is guided into the blood vessel through the guide wire, and after the catheter arrives at the blocked lesion, the guide wire is supported and assisted in jointly passing through the blocked lesion in the blood vessel; in the operation process, by rotating the catheter connector, the blocked lesion in the blood vessel can be more easily incised.

Description

technical field [0001] The invention relates to an intravascular support catheter, in particular to an intravascular support catheter with a rotary cutting tip. Background technique [0002] Lower extremity arteriosclerosis obliterans (PAD) is due to the formation of lower extremity atherosclerotic plaques, causing lower extremity arterial stenosis and occlusion, leading to chronic ischemia of the limbs. With the improvement of the overall living standard of the society and the aging of the population, the incidence of lower extremity arteriosclerosis obliterans increases year by year. Symptomatic PAD patients account for 4.5% of the population aged 55 to 74, and approximately 20% of older adults have symptomatic or asymptomatic PAD (German Association of Angiology and Association of Vascular Medicine). [0003] Epidemiological surveys have shown that smoking, diabetes, hyperlipidemia, hypertension, hyperhomocysteinemia, hypercoagulability, increased blood adhesion and adva...
