Problems solved by technology

[0007] The technical problem to be solved by the present invention is the problem of frequent contact between the measuring tool and the stent resulting in damage to the pipe wall caused by the use of contact measurement of the medical stent pipe material. The present invention provides a new automatic measurement method for the pipe diameter of the medical stent pipe material. The contact probe measures the pipe diameter of the support pipe, avoiding the damage to the pipe wall caused by the contact measurement tool due to frequent contact with the support pipe

Abstract

The invention relates to an automatic measuring method for the pipe diameter of a medical bracket pipe. The automatic measuring method for the pipe diameter of the medical bracket pipe mainly solves the problems that in the prior art, a contact measuring method is adopted, a measuring tool makes frequent contact with the medical bracket pipe, and a pipe wall is damaged as a result. Automatic measuring equipment adopted in the automatic measuring method comprises a measuring platform and feeding supporting modules. A measuring shafting system is fixed on the measuring platform. The measuring platform comprises a rotating shaft. A measuring equipment control system is arranged below the measuring platform. An automatic feeding clamping mechanism, a fixed shaft, a straight line shaft, a rotating shaft and oppositely-radiating measuring heads are installed on the measuring platform. According to the technical scheme, a bushing hole is formed in the automatic feeding clamping mechanism, and the feeding supporting modules are arranged on the left side and the right side of the measuring platform, so that the problems are well solved, and the automatic measuring method for the pipe diameter of the medical bracket pipe can be used in the medical bracket pipe measuring equipment manufacturing industry.

Description

[0001] technical field [0002] The invention relates to an automatic measuring method for the pipe diameter of a medical support pipe. 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 of interventional...
