Intravascular stent releasing device

Abstract

The invention relates to the field of medical instruments, in particular to an intravascular stent releasing device. The intravascular stent releasing device comprises a foot stool, an inner pipe, a middle pipe and an outer pipe; the foot stool is provided with a center section, a pushing section connected to one end of the center section and a recycling section connected to the other end of the center section, the pushing section is provided with a pushing clamping jaw elastically extending outwards in the radial direction in the far-end direction, and the recycling section is provided with a recycling clamping jaw elastically extending outwards in the radial direction in the near-end direction; the inner pipe is fixedly connected with the central section of the foot stool; the middle pipe sleeves the inner pipe and the foot stool, the far end of the middle pipe is provided with a first opening suitable for the pushing section of the foot stool to extend out, the side wall of the far end of the middle pipe is provided with a second opening suitable for the recovery section of the foot stool to extend out, when the pushing section of the foot stool extends out of the first opening, the recycling section of the foot stool retracts into the middle pipe, and when the recycling section of the foot stool extends out of the second opening, the pushing section of the foot stool retracts into the middle pipe; and the middle pipe sleeves the outer pipe, and the space between the outer pipe and the middle pipe is suitable for containing a stent.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a vascular stent releasing device. Background technique [0002] Atherosclerotic stenosis is the main cause of coronary heart disease, cerebral infarction, and peripheral vascular disease. Atherosclerosis is called atherosclerosis because of the yellow ather-like appearance of lipids that build up in the lining of the arteries. [0003] Active and effective treatment of arterial stenosis is of great significance to the prevention and treatment of stroke. At present, the prevention of atherosclerotic lesions often adopts the control of vascular risk factors, antiplatelet, anticoagulant and antihypertensive treatments, but it is difficult to have a satisfactory effect on the treatment of arterial lesions. [0004] With the advancement of technology, angioplasty and stenting have become effective means of treating arterial stenosis because of their advantages of safety, reliability,...
