Improve the endoscopic imaging method for qualityTechnical field
The present invention relates to a kind of medicine equipment, especially a kind of endoscope, specifically a kind of raising endoscopic imaging method for quality.
Background technology
As everyone knows, endoscope is one of basic condition of Minimally Invasive Surgery, and the research of relevant diagnoses and treatment equipment, exploitation, production etc. seem particularly important.Have only few countries can produce ultra-fine, extra small endoscope in the world; Main manufacturer has: Japanese Anxi, German platinum power, Olympus etc., and description reaches tens kinds, and the trend of development is: dwindle lenslet dimension and the diameter that passes the light coherent fiber bundle, raising image quality; Rotatable, improve objective system and bending actuating mechanism; Flexibility is good and eliminate viewing blind zone, improves operating performance, the direction accurate and adjustable, makes every effort to easy to use; Can be used as biopsy channel, and can cooperate gasification treatment such as to melt; Can extend to diagnosis and treatment aspects such as bile duct, ductus pancreaticus, blood vessel, ophthalmology, joints clinically.
In the process of the actual use of endoscope; A large amount of experiments is found; The unintelligible reduction that brings image quality of protective casing; Influenced the effect of clinical diagnosis, especially in the operation occasion that can not carry out normal saline flushing, the sticky object on protective sleeve surface has influenced the sharpness of the visual field in the experiment.Therefore making protective casing have the hydrophobic oleophobic characteristic is to improve the endoscopic imaging quality; Improve the key of medical level; Form on the surface of protective casing that a kind of can to satisfy rete hydrophobic, oleophobic simultaneously be the task of top priority, this rete can not be damaged in the process of solvent sterilization simultaneously.
Summary of the invention
The objective of the invention is not cause image quality poor because of protective sleeve does not possess the hydrophobic oleophobic function to existing endoscope use; Influence the problem of diagnostic accuracy; Invent a kind of through form both hydrophobic, the oleophobic of one deck on protective sleeve surface, the raising endoscopic imaging method for quality of the diaphragm that can not damage because of sterilization again.
One of technical scheme of the present invention is:
A kind of raising endoscopic imaging method for quality is characterized in that having the hydrophobic oleophobic function and hydrophobic by following method formation and the separated diaphragm that is provided with of oleophobic interlayer on the surface of endoscope protective sleeve:
At first, on theoutside surface 4 of protective sleeve base material, apply onedeck photoresist 3;
Secondly, on photoresist, cover mask 2 with required pattern;
The 3rd, utilize the above-mentionedoutside surface 4 that is coated with the protective sleeve of mask 2 ofultraviolet light 1 irradiation;
The 4th, thephotoresist 3 of the part that will be shone byultraviolet light 1 washes, and the exposure that the pattern with mask 2 matches onoutside surface 4, occurs;
The 5th, the also oleophobic rete 5 of covering one deck oleophobic on aforementioned exposure;
The 6th, throw off mask, will be washed by thephotoresist 3 that mask covers once more;
The 7th, on theoutside surface 4 of protective sleeve, apply onedeck photoresist 3 once more;
The 8th, mask film covering once more on the zone of uncoated oleophobic rete 5 is utilized the zone of the uncoated oleophobic rete 5 of ultraviolet ray irradiation, and will be washed through the photoresist in ultraviolet radiation zone territory, forms hydrophobic surface;
The 9th, applyhydrophobic film layer 6 at above-mentioned hydrophobic surface;
The tenth; Remove mask once more; Protective sleeve the photoresist that is coated on the oleophobic rete 5 washed the protective seam that promptly is arranged at intervals with oleophobic rete 5 andhydrophobic film layer 6 atoutside surface 4 formation one decks of protective sleeve, so that in use can not glue the sticking water of oil and keep the visual field clear.
Described oleophobic rete 5 is identical with the thickness ofhydrophobic film layer 6, is 100 nanometers-10 micron.
Two of technical scheme of the present invention is:
A kind of raising endoscopic imaging method for quality is characterized in that adopting the method for twice serigraphy to form oleophobic rete and the hydrophobic film layer that one deck is provided with at interval at the outside surface of the base material of endoscope protective sleeve.
Beneficial effect of the present invention:
The present invention has formed the not only diaphragm of the hydrophobic but also ability thimerosal of oleophobic of one deck through photoetching process on the surface of protective sleeve, make can obtain distinct image all the time in the endoscope use, lays a good foundation for improving diagnostic level.
Description of drawings
Fig. 1 is the process flow diagram that photoetching process of the present invention is made the hydrophobic oleophobic diaphragm.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Embodiment one.
As shown in Figure 1.
A kind of raising endoscopic imaging method for quality; It that has a hydrophobic oleophobic function and hydrophobicly realizes with the method for oleophobic interlayer at a distance from the diaphragm that is provided with through forming on the surface of endoscope protective sleeve, describedly hydrophobicly with the oleophobic interlayer at a distance from the photoetching process manufacturing approach of the diaphragm of setting is:
At first, on theoutside surface 4 of protective sleeve base material (can be medical materials such as plastics, glass), apply onedeck photoresist 3;
Secondly, on photoresist, cover mask 2 (pattern can design with imaging requirements as required voluntarily) with required pattern;
The 3rd, utilize the above-mentionedoutside surface 4 that is coated with the protective sleeve of mask 2 ofultraviolet light 1 irradiation;
The 4th, thephotoresist 3 of the part that will be shone byultraviolet light 1 washes, and the exposure that the pattern with mask 2 matches onoutside surface 4, occurs;
The 5th, the also oleophobic rete 5 of covering one deck oleophobic on aforementioned exposure;
The 6th, throw off mask, will be washed by thephotoresist 3 that mask covers once more;
The 7th, on theoutside surface 4 of protective sleeve, apply onedeck photoresist 3 once more;
The 8th, mask film covering once more on the zone of uncoated oleophobic rete 5 is utilized the zone of the uncoated oleophobic rete 5 of ultraviolet ray irradiation, and will be washed through the photoresist in ultraviolet radiation zone territory, forms hydrophobic surface;
The 9th, applyhydrophobic film layer 6 at above-mentioned hydrophobic surface;
The tenth; Remove mask once more; The photoresist that is coated on the oleophobic rete 5 is washed the protective seam that promptly is arranged at intervals with oleophobic rete 5 andhydrophobic film layer 6 atoutside surface 4 formation one decks of protective sleeve; The thickness of this protective seam is between 100 nanometers-10 micron, so that protective sleeve in use can not glue the sticking water of oil and keep the visual field clear.
The hydrophobic oleophobic coating of using during practical implementation only need satisfy medical requirement and get final product, and its prescription can be prepared voluntarily, also can directly purchase from market.
Embodiment two.
A kind of raising endoscopic imaging method for quality, it is that outside surface at the base material of endoscope protective sleeve adopts the method for twice serigraphy to form oleophobic rete and the hydrophobic film layer that one deck is provided with at interval.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
