An arterial rotary grinding interventional device

Abstract

The invention discloses an arterial rotary grinding interventional device, which relates to the technical field of arterial rotary grinding. The invention comprises a controller, an electric motor, aspeed regulator, an air pump, a waste liquid tank, a cleaning box and a water pump, wherein the water outlet of the water pump is fixed with a first water pipe, the air outlet of the air pump is fixedwith an air pipe, a rotating thread is fixed at one end of the output shaft of the electric motor, and a liquid discharge pipe is fixed at the liquid inlet of the waste liquid tank. The cleaning liquid in the cleaning box is pumped to a polishing place by a water pump, the flushed waste liquid will flow into the waste liquid tank along the drain pipe, so that the ground debris can be discharged out of the body in time, the air is introduced into the air bag through the air pump along the air pipe. The constricted air bag is stuck on the blood vessel wall, and the conical grinding head is supported and fixed. The sliding key in the speed governor is controlled by hand, so that the motor is adjusted to the proper rotational speed. The surface of the speed governor is scaled, so that the rotational speed of the motor can be known in time, and the arterial rotary grinding intervene device is convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of arterial rotational atherectomy, in particular to an arterial rotational atherectomy intervention device. Background technique [0002] Rotational atherectomy is mainly suitable for anatomically high-risk lesions, such as calcified lesions, lesions at openings, lesions that are difficult to expand with a balloon, and long-segment vascular lesions. Judging from the classification of coronary lesions, these lesions are mostly type C lesions, with low PTCA power and high incidence of complications. rate decreased significantly. [0003] When the spindle-shaped grinding head at the front end of the existing arterial rotary atherectomy device is polished, a lot of debris will be generated, and the debris produced cannot be discharged in time, which will directly lead to the accumulation of debris again, resulting in similar diseases and affecting treatment. As a result, the rotating grinding head of the exis...

Problems solved by technology

[0004] The object of the present invention is to provide an arterial rotational atherectomy device, which pumps the cleaning liquid in the cleaning tank to the grinding position through a water pump, and the waste liquid after washing will flow into the waste liquid tank along the drain pipe, which solves the problem of existing arterial atherectomy. When the spindle-shaped grinding head at the front end of the rotary atherectomy device is grinding, a lot of debris will be generated and cannot be discharged in time, which will directly lead to the problem of debris accumulation again

Through the air pump, the air is passed into the air bag along the trachea, so that the contracted air bag becomes larger and stuck on the blood vessel wall, which supports and fixes the tapered grinding head, and solves the problem of rotating grinding of the existing arterial rotational atherectomy device When the head is being polished, it is not easy to control, and there is no problem with the supporting structure. By using the sliding key in the governor by hand, the motor can be adjusted to an appropriate speed, which solves the speed control of the motor for the existing arterial rotational atherectomy interventional device Most of them adopt the control method of pedaling. When operating, the speed of the motor will not be easy to control, which will affect the control of the surgical effect.
