Embodiment Construction

[0060] Below in conjunction with accompanying drawing, the present invention will be further described by specific embodiment:

[0061] See Figure 1~8 , a cleaning system with a variable cutting diameter intraluminal plaque capture mechanism, including a variable cutting diameter intraluminal plaque capture mechanism, and also includes an outer handle a1, an inner handle b1, a plaque exporting assembly, and a shaft tube Transition assembly and axle tube drive assembly. The intraluminal plaque capture mechanism with variable cutting diameter includes a clearing cutter head, a plaque transport component and a cutting diameter adjustment component. The plaque exporting component includes a plaque transfer cavity b6 connected to the transport sleeve b3 and a plaque export tube b61 connected to the plaque transfer cavity b6. The plaque transfer cavity b6 communicates with the plaque transport channel, and the plaque transport The channel is set in the plaque transport assembly, ...

Abstract

The invention provides a cutting diameter-adjustable intracavity plaque capturing mechanism. The cutting diameter-adjustable intracavity plaque capturing mechanism comprises a cleaning cutter head, aplaque transportation assembly and a cutting diameter adjusting assembly. A cleaning system with the capturing mechanism comprises the cutting diameter-adjustable intracavity plaque capturing mechanism, and further comprises an external handle, an internal handle, a plaque lead-out assembly, a shaft tube transition assembly and a shaft tube driving assembly. The structures are compact but not complicated, the operation is convenient and easy to understand, forward cutting and reverse cutting can be achieved, and the cutting diameter can be adjusted. The assembly pipe bodies are high in flexibility and can be easily pushed, the cutter head is good in cutting effect and high in efficiency, the structures are reasonable in layout and high in strength, assembly is easy, the cost investment islow, and the cutting diameter-adjustable intracavity plaque capturing mechanism is worthy of application and popularization in the field.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intracavity plaque capture mechanism with variable cutting diameter and its associated cleaning system. Background technique [0002] Occlusion of the vascular lumen, severe atherosclerosis in the cavity, and calcified lesions are common lumen diseases. Without timely treatment and surgery, it will lead to serious damage to the cardiovascular and cerebrovascular systems, which may be life-threatening if necessary. Balloon angioplasty and Stenting is a common treatment tool and method for treating such diseases. However, for severe luminal occlusion, plaque accumulation, and severe calcified lesions, it is difficult for ordinary balloon angioplasty to pass through and expand the lesion to restore normal blood flow. Even with high-pressure balloon expansion, it is easy to cause vascular rupture, dissection and Postoperative vascular restenosis and other adverse conseque...
