Problems solved by technology

[0007] The technical problem to be solved by the present invention is the low qualified rate of traditional Chinese medical stents after laser cutting in the prior art. The present invention provides a new processing equipment for automatically compensating the diameter tolerance of medical stents. The advantages of inconsistent or even out-of-tolerance and scrapping of the final cut stent due to the change of pipe diameter at each point

Abstract

The invention relates to automatic compensating machining equipment of medical bracket pipe diameter tolerance, which is mainly used for solving the problem that the qualification rate after the laser cutting of the bracket in the prior art is low. The automatic compensating machining equipment of medical bracket pipe diameter tolerance comprises a bracket laser cutter, an opposite irradiating measuring head and a control system processing center; the opposite irradiating measuring head is arranged between a pipe chuck on a two-dimensional motion platform in the bracket laser cutter and a clamping lining sleeve of the pipe close to the cutting area; according to the technical scheme, when the pipe is in a cutting status, the bracket clamp is clamped on the chuck, the chuck is fixed on the rotary shaft, and the bracket pipe is arranged between a signal generator and a signal receiver of the opposite irradiating measuring head, so that the problem is well solved, and the automatic compensating machining equipment of medical bracket pipe diameter tolerance can be used in the medical bracket pipe measuring device manufacturing industry.

Description

[0001] technical field [0002] The invention relates to a processing device for automatically compensating the diameter tolerance of a medical bracket. Background technique [0003] With the rapid development of material science and precision micromachining technology, there are more and more types of medical stent materials. The more common ones are stainless steel 316L, nickel-titanium alloy, cobalt-based alloy, pure iron, magnesium alloy and other metal materials, as well as polymers, etc. non-metallic materials. Because the medical stent expands the vascular wall in the blood vessel to prevent vasoconstriction or even cause various diseases, it is required that the characteristic structure and size of the ribs on the stent be consistent in order to maintain the same tension at each point of the whole stent. The bracket processing technology puts forward higher requirements. Generally, medical stents are processed with seamless pipes. Due to the incomplete development ...
