Embodiment 1

[0044] A method for processing a medical bracket, the equipment used includes automatic compensation equipment for pipe diameter tolerance and automatic measurement equipment for pipe diameter, and the automatic compensation equipment for pipe diameter tolerance includes a bracket laser cutting machine, a through-beam measuring head and a control system processing center. The measuring head is installed between the pipe chuck on the two-dimensional motion platform in the bracket laser cutting machine and the clamping bushing near the cutting area of ​​the pipe; when the pipe is in the cutting state, the bracket pipe is clamped on the chuck, and the chuck It is fixed on the rotating shaft, and the bracket pipe is between the signal generator and the signal receiver of the through-beam measuring head; the linear axis will drive the rotating shaft to move to the right, and the through-beam measuring head will detect the actual pipe diameter of each point in real time, and the measu...

Embodiment 2

[0057] A processing method of a medical bracket, the automatic compensation processing method is the same as in embodiment 1.

[0058] A processing method for automatically compensating the diameter tolerance of a medical stent, which uses the through-beam measuring head ( figure 2 2) Mounted on the bracket laser cutting machine ( Figure 4 Shown) Inner two-dimensional motion platform ( figure 2 5 and 6) on the pipe clamp ( figure 2 middle 4) and the clamping bushing near the cutting area of ​​the pipe ( figure 2 1) between, just to allow the bracket tubing ( figure 2 3) The signal generator in the through-beam measuring head ( image 3 8) and the signal receiver ( image 3 7), the bracket tubing is first placed directly on the feed support module ( Figure 4 12) and pass through the rotation axis on the two-dimensional motion platform ( figure 2 Middle 5), the middle passes through the pipe chuck ( figure 2 Middle 4) until the pipe bushing ( figure 2 Middle 1...

Embodiment 3

[0063] A kind of processing method of medical support, with embodiment 1.

[0064] Medical bracket pipe diameter tolerance automatic compensation processing equipment, including bracket laser cutting machine, through-beam measuring head and control system processing center, through-beam measuring head installed on the two-dimensional motion platform in the bracket laser cutting machine, pipe chuck and pipe close to cutting Between the clamping bushes in the area; when the pipe is in the cutting state, the bracket pipe is clamped on the chuck, the chuck is fixed on the rotating shaft, and the bracket pipe is in the signal generator and signal receiver of the beam probe between; the linear axis will drive the rotary axis to move to the right, and the beam measuring head will detect the actual pipe diameter at each point in real time, and the measured actual pipe diameter data will be transmitted to the control system processing center through Ethernet, and the processing center w...

Abstract

The invention relates to a medical bracket machining method 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 equipment for the medical bracket machining method comprises a pipe diameter tolerance self-compensating device and a pipe diameter automatic measuring device, wherein the pipe diameter tolerance self-compensating device 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 medical bracket machining method can be used in the medical bracket pipe measuring device manufacturing industry.

Description

[0001] technical field [0002] The invention relates to a processing method for 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 of interventional surgery in the world and the unbala...
