Abstract
The invention discloses an illumination method for medical support detection. The illumination method comprises the following steps of providing a quartz rod of which an external diameter matches with an internal diameter of a support sample, assembling the quartz rod and the support sample, and irradiating an external surface area of the support sample by an external light source, wherein under the irradiation of the external light source, the quartz rod emits white fluorescent to irradiate an internal surface area of the support sample. The illumination method realizes selective illumination of the internal surface area and the external surface area of the support sample.
Description
Technical field
The present invention relates to laser micro-machining technology, be specifically related to a kind of means of illumination that is applicable to that medical support detects.
Background technology
Can play the effect of bracing frame in the medical support implantable intravascular, thereby 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 all is a minor diameter generally, and diameter is approximately 1mm, 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.
In the support testing process, rack outer surface zone and inner surface area all must be detected.Yet, because inside and outside surf zone is thrown light on simultaneously by same light source, scattering phenomenon can take place, it is image blurring unclear to make that CCD scanning obtains.This will hinder the degree of accuracy of manual detection, and hinder simultaneously and utilize image processing algorithm to detect automatically.
Therefore, need a kind of means of illumination that is applicable to that medical support detects in the art.
Summary of the invention
The present invention's solution inside and outside surf zone in support product testing process is caused technical matterss such as scattering phenomenon by illumination simultaneously.
For solving the problems of the technologies described above, the invention discloses a kind of means of illumination that is applicable to that medical support detects.This means of illumination comprises: the quartz pushrod that provides the internal diameter of external diameter and support sample to be complementary, and quartz pushrod cooperated installation with the support sample; And the outer surface region of shining the support sample with external light source, simultaneously quartz pushrod externally sends the inner surface area that white fluorescent shines the support sample under the irradiation of light source, thereby realizes the selective illumination to the outer surface region and the inner surface area of support sample.
In the present invention, adopt the illumination of different colours and type bright respectively, suppressed scattering phenomenon, thereby obtain scan image clearly support product inside and outside.

Reference numeral:
1. external light source, 2. quartz pushrod, 3. support sample, 4. electronics line array CCD
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.
According to an embodiment, the present invention introduces a kind of means of illumination.This means of illumination allows in the space of a limitation outer surface regions and inner surface area to be carried out selective illumination.Particularly, the invention provides the quartz pushrod that the internal diameter of external diameter and support sample is complementary, and quartz pushrod is cooperated installation with the support sample, make the rotation of quartz pushrod can drive the rotation of support sample so that comprehensive detection.Like this, when external light source shines the outer surface region of support sample, also can be radiated on the quartz pushrod.Quartz pushrod externally sends white fluorescent under the irradiation of light source, thereby shines the inner surface area of support sample.The irradiation of external light source makes quartz pushrod send stable white fluorescent, and the light color that this light and the external light source that sends on the quartz pushrod sends is dissimilar also different.Therefore, two kinds of different light of wavelength illuminate the inside surface and the outside surface of support product respectively, are equivalent to have simultaneously outside and inner two different lighting sources.
In addition, use electronic image system to be connected with CCD based on personal computer.When sample under CCD during around the rotation of its length direction, picture system produces along the bar graph picture in the zone of sample length direction, thereby obtains the scan image clear, that scattering is few.
Claims (2)
1. means of illumination that is applicable to that medical support detects comprises:
The quartz pushrod that provides the internal diameter of external diameter and support sample to be complementary, and quartz pushrod cooperated installation with the support sample; And the outer surface region of shining the support sample with external light source, simultaneously quartz pushrod externally sends the inner surface area that white fluorescent shines the support sample under the irradiation of light source, thereby realizes the selective illumination to the outer surface region and the inner surface area of support sample.
2. means of illumination as claimed in claim 1 is characterized in that, the light that quartz pushrod sends is different with the light wavelength that external light source sends.
