The medical support detection system comprises 1, a two-dimensional motion platform which is used for moving a support sample, 2, an external light source which is used for illuminating an outer surface area of the support sample, 3, an electronic linear array CCD which is installed above the support sample and is used for scanning the support sample by a line-by-line scanning method, 4, an image processing device which is coupled with the electronic linear array CCD, and 5, a display device which is coupled with the image processing device. The medical support detection system also comprises a quartz rod. The external diameter of the quartz rod matches with the internal diameter of the support sample so that the quartz rod and the support sample can be assembled. When the external light source irradiates the quartz rod, white fluorescent emitted by the quartz rod irradiates the inner surface area of the support sample.
Description
?
Technical field
The present invention relates to the thin-wall pipes laser micro-machining technology, relate in particular to a kind of medical support detection system.
Background technology
Can play the effect of bracing frame in the medical support implantable intravascular, in order to keep opening of blood vessel.Medical support must satisfy strict job requirement, if support comprises any coarse or sharp-pointed limit, it will damage the haemocyte or the vascular wall at implant frame place, and this will cause further vascular diseases, so that has potential life danger.Support generally all is a minor diameter, the about 1mm of diameter, and after carrying out laser cutting parameter, the size of various cutting features is probably between 50 ~ 200um on the support.General, the subtle change of parameter in the process for making all can cause defective as laser power, caliber size or machinery vibration.Because the inefficacy of support on function may cause life danger, so the detection link of support after machining is even more important.
Existing detection means has manual detection and vision system to detect automatically.Manual detection is the support product to be detected one by one by microscope by the people.There is bigger error in this manual detection mode, and manual detection is relatively slow and the cost of manufacturing process is promoted relatively in addition.And existing vision automatic checkout equipment is extremely complicated, and the equipment set price is also very expensive.
Therefore be necessary to provide a kind of fast, detection system cheaply so that expeditiously qualified and underproof support product zone is separated.

Summary of the invention
The present invention aims to provide a kind of system that is used to detect the support product simply, efficiently.
For solving the problems of the technologies described above, the invention discloses a kind of medical support detection system.This system comprises: two-dimension moving platform is used for the traversing carriage sample so that detect each zone of support sample; External light source, the outer surface region that is used to shine the support sample; Be installed in the electronics line array CCD of support sample top, be used for the support sample is scanned, to obtain the general image of support sample by the line sweep mode; Image processing apparatus with the coupling of electronics line array CCD is used for the data of electronics line array CCD collection are handled; And with the display device of image processing apparatus coupling, be used for the result of display image treating apparatus.This system also comprises quartz pushrod, and the external diameter of quartz pushrod is complementary so that both cooperate installation with the internal diameter of support sample, and quartz pushrod sends the inner surface area of white fluorescent with irradiation support sample when external light source is radiated on the quartz pushrod.
Detection system provided by the invention is simple, and is with low cost, and can detect the support product expeditiously.

Embodiment
Each preferred embodiment of the present invention below will be discussed.But it will be appreciated by those skilled in the art that herein detailed description not as limiting the scope of the invention, the present invention also can be achieved by modification or other equivalent way of following each embodiment.
After the support processing some defectives may appear, as shown in Figure 1.Therefore be necessary to detect the wide consistance in footpath of support various piece, whether shape meets the requirements, and wall thickness etc.
Fig. 2 illustrates support detection system according to an embodiment of the invention.As shown in the figure, this detection system comprises two-dimension moving platform, electronics line array CCD, external light source, image processing apparatus and display device etc.
Two-dimension moving platform is used for the traversing carriage sample, so that detect each zone of support sample.In an example of the present invention, two-dimension moving platform comprises linear axis and turning axle.As shown in the figure, turning axle is used for the clamping quartz pushrod, and quartz pushrod is rotated around Y-axis.Y-axis can be used to the relative position of locating support sample and line array CCD.According to one embodiment of present invention, the internal diameter of support sample is complementary with the external diameter of quartz pushrod so that both can cooperate installation, and the rotation of turning axle makes the quartz pushrod of clamping rotate and and then drive support sample rotation.So, can make sample be detected by rotation mode.Turning axle can be installed on the linear axis, and linear axis driven rotary axle moves along X-direction.Therefore support can be placed on any position, thereby can be checked through all limits on the support.
The electronics line array CCD is used for test sample.CCD is installed in the top of support, the view data of gathering support in the precision sweep mode of a line of a line.
Detection system is introduced illuminator from the outside, is used to be radiated at the outer surface region of support.In addition, external light source is radiated on the quartz pushrod, makes quartz pushrod send white light, thereby is radiated on the inner surface area of support.Therefore, detection system of the present invention is equivalent to have simultaneously outside and inner two lighting sources.
Image processing apparatus and the coupling of electronics line array CCD are used for the view data of electronics line array CCD collection is handled.In one example, this image processing apparatus can be based on the analysis module of computing machine.
Display device and image processing apparatus coupling are used for by the result of user interface to user's display image treating apparatus.
When utilizing detection system of the present invention to detect, external light source is radiated at the outside surface of support, and quartz pushrod is radiated at the inside surface of support owing to white light is sent in the irradiation of external light source simultaneously.So, the outside of support is shone by different lighting sources respectively with inner.The precision of standard quartz rod is very good, and error level is very low, is benchmark with it, wall thickness that just can the measurement bracket pipe.Utilize the linear axis and the turning axle traversing carriage of two-dimension moving platform, make each zone of support all be scanned by CCD.Particularly, the high speed rotating of turning axle drives the support product rotation on the quartz pushrod, also can be moved in the horizontal direction by linear axis driven rotary axle simultaneously.Like this, CCD after a complete scanning process, just can obtain the general image of support to collect each regional view data of support by the line sweep mode.The result of scanning process is the image of the high degrees of detail of support, can utilize image processing algorithm that this image is handled, observing the structure or the surface imperfection of number of different types, and the theory or the design basis of these defectives and former definition compared, thereby be presented on the computer interface.
As seen, detection system provided by the invention is simple, and is with low cost, and can be expeditiously with qualified and underproof support product zone separately.
