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

Embodiment 1

[0035] A medical stent processing equipment, including pipe diameter tolerance automatic compensation equipment and pipe diameter automatic measurement equipment, the pipe diameter tolerance automatic compensation equipment includes a bracket laser cutting machine, through-beam measuring head and control system processing center, through-beam measuring head 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 is fixed On the rotation axis, the bracket pipe is between the signal generator and the signal receiver of the through-beam probe; the linear axis will drive the rotation axis to move to the right, and the through-beam probe will detect the actual pipe diameter of each point in real time, and the measured actual The pipe diameter data is transmitted to the process...

Embodiment 2

[0040] A processing method for automatically compensating the diameter tolerance of a medical stent, the method adopts 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) The cutting head at the right end is in the cutting area below. Due to the bracket tubing ( figure 2 Middle 3) First ...

Embodiment 3

[0045] A medical bracket pipe diameter tolerance automatic compensation processing equipment, including a bracket laser cutting machine, a through-beam measuring head and a control system processing center, the through-beam measuring head is installed on the two-dimensional motion platform in the bracket laser cutting machine, the pipe chuck and the pipe Between the clamping bushes close to the cutting 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 of the beam probe Between the receivers; 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 will compare them in real time The measured change i...

Abstract

The invention relates to medical bracket machining equipment 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 medical bracket machining equipment 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 equipment can be used in the medical bracket pipe measuring device manufacturing industry.

Description

[0001] technical field [0002] The invention relates to a medical bracket processing equipment. 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 unbalance...
