Vascular stent cutting device and vascular stent cutting method

Abstract

The invention discloses a vascular stent cutting device and a vascular stent cutting method, belonging to the technical field of medical apparatus processing equipment. The vascular stent cutting device comprises an X-X workbench, a platform, a laser cutting head system and a control system, wherein the X-X workbench is a two-dimensional movement feeding platform which is composed of an X-axis linear motor capable of horizontally moving along the X-axis and an X-axis rotating motor capable of rotating around the X-axis; the X-axis rotating motor is provided with a workpiece fixture; the platform is in counter weight with the X-X workbench; the laser cutting head system comprises a laser generator and a Z workbench; and the Z workbench is a moving platform which is composed of a Z-axis servo motor capable of moving along the vertical direction. A processing and cutting device for producing a vascular stent provided by the invention realizes that the production efficiency of the vascular stent is high, and the production cost of the vascular stent is low, so as to conveniently and effectively process the vascular stents with various shapes. The vascular stent cutting device solves the problems existing in a vascular stent processing device that the miniaturization is not enough, the processing precision is not high, the cutting is slow, the heat affected zone is larger, the service life is short, the production cost is high, etc.

Description

technical field [0001] The invention belongs to the technical field of medical device processing equipment, in particular to the field of micromachining of brackets of different materials and tubular thin-walled materials, and specifically relates to a cutting equipment and method for a blood vessel bracket. Background technique [0002] At present, the effectiveness and safety of vascular stent technology in the treatment of vascular stenosis have been widely recognized in clinical applications, and it has become a new treatment technology, forming a broad market demand. Some large medical device companies in the world have launched their own vascular stent products, such as Cordis, Medtronic, Boston, Scientific and Guidant, etc. The stent products of these large companies occupy most of the international market. Domestic companies such as Minimally Invasive Medical Devices (Shanghai) Co., Ltd. have independently developed the Mustang coronary stent and the Firebird drug st...

AI Technical Summary

Problems solved by technology

Most of the existing vascular stent cutting equipment uses Nd:YAG laser, which has defects such as short lamp life, low conversion efficiency, large energy consumption, insufficient miniaturization of the system, low precision, slow cutting, large heat-affected zone, and high production cost.

[0005] The development of vascular stent processing in China is relatively late, the technology is relatively backward, and there is a big gap between the processing accuracy and quality compared with foreign countries. Medical vascular stents mainly rely on imports, and the high cost is beyond the reach of the general public. How to develop a vascular stent processing The ability of equipment to process low-cost, high-precision and high-quality vascular stents is a major issue facing Chinese researchers
