Problems solved by technology

[0005] 1. The high-speed rotation of the diamond grinding head and the grinding head carrier in the human body will generate a lot of heat, which may cause a series of complications in patients, such as vasospasm, acute thrombosis, and acute myocardial infarction;
[0006] 2. During use, a large amount of lubricating coolant solution is used to enter the human artery, which brings a greater burden to the human kidney function;
[0007] 3. The driving motor and high-pressure gas will generate huge noise during use;
[0010] 1. Motor-driven, the structure and shape of the diamond grinding head is aimed at the forward narrow a

Embodiment Construction

[0046] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The rotary atherectomy device for intravascular calcification lesions of the present invention uses high-pressure liquid to impact the water wheel to convert kinetic energy into mechanical energy for the water wheel to rotate. Severely calcified or fibrotic atherosclerotic lesions with severe constriction in peripheral and coronary vessels.

[0047] like figure 1 As shown, the rotational atherectomy device for intravascular calcification lesions of the present invention is provided with a constant pressure water pump, a water flow control valve, a water turbine and a rotational atherectomy head connected in sequence from the proximal end to the distal end, and the water turbine is composed of a water wheel and a transmission acceleration mechanism. connection composition.

[0048] The output liquid (water) pressure of the constant pressure water...

Abstract

The invention discloses an intravascular calcification lesion rotary grinding device, and aims to improve the safety of an operation and reduce the cost. According to the technical scheme, the rotary grinding equipment for the intravascular calcification lesion is provided with a rotary grinding head and is characterized in that the rotary grinding head is driven by a water pump through a water turbine to rotate. Compared with the prior art, high-pressure liquid is adopted to impact the water wheel to convert liquid kinetic energy into water wheel rotation mechanical energy, the transmission acceleration mechanism is driven to achieve rotation of the rotary grinding head, and the rotary grinding head is used for dredging or improving severe and narrow severe calcification or fibrosis atherosclerotic lesions on the periphery of a human body and in coronary vessels. The rotary grinding head rotates at a high speed, transmission noise is low, friction heat left in the human body due to rotary grinding is reduced, the amount of cooling and lubricating solution input into the human body is reduced, the metabolic burden of the kidney of the human body is relieved, and the rotary grinding head is safe, reliable, simple in structure and low in cost.

Description

technical field [0001] The invention relates to a medical device, in particular to a device for interventional treatment of coronary artery calcification lesions. [0002] technical background [0003] Rotational atherectomy (Rotational atherectomy) is an indispensable operation for successful completion of percutaneous coronary intervention PCI in some special lesions such as severe calcified lesions. For some severe stenosis, severe calcification or fibrosis, it is a clinically useful interventional therapy. In the prior art, a rotational atherectomy device is used, and a high-speed rotating diamond grinding head is used in the coronary artery of the human body, and the lesions in the artery are rotationally abraded to dredge the severely occluded coronary artery. One of them is to use a high-speed motor to drive the diamond grinding head to rotate, and the representative product is the CSI Diamondback360 Coronary Orbital Atherectomy System. The other is to use high-press...
