Abstract

The invention provides a laser processing device of a vascular bracket. The device consists of a rotary shaft, a linear shaft, a laser cutting head, an assistant high pressure gas supply unit, a Z-axis module, a laser generator, a collimation and beam expanding mirror, an irradiation light source, a 45-degree reflective mirror, a CCD (Charge Coupled Device) and a control system. The CCD receives light reflected by the 45-degree reflective mirror, is used for observing spot focusing condition when the laser spot position is adjusted, and meanwhile checks processing condition any time in the process as well as records the whole course of the process. The control system comprises a motion control unit for controlling the linear shaft, the rotary shaft and the Z-axis module and a laser control unit for controlling the laser generator. The laser processing device of the vascular bracket provided by the invention is fast in processing speed and high in processing precision. The functional blocks are designed in a modularized manner, so that the device is strong in interchangeability, easy to upgrade and compact in structure. The bracket product obtained can meet the precision demand of medical apparatuses, and the massive localization process of the vascular brackets is greatly promoted.

Description

technical field [0001] The invention belongs to the field of laser micromachining of thin-walled pipe materials, and relates to a laser processing device, in particular to a laser processing device for a blood vessel stent. Background technique [0002] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of luminal balloon expansion to support the stenotic and occluded segment of the vessel, reduce the elastic retraction and reshaping of the vessel, and maintain the smooth blood flow in the lumen. The role of the scaffold is to keep the blood vessels open. Some internal stents can also prevent restenosis. Mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic stents, etc. [0003] The processing of vascular stents in my country develops late, the technology is relatively backward, and there is a big gap in processing accuracy and quality compared with foreign countries. At present, most of the ste...
