Description
Technical field
It the utility model is related to a kind of endoscope head, more particularly to a kind of endoscope head with anti-smog device.
Background technology
With the development of science and technology, medical endoscope has been widely used in medical field.It is human diagnostic,
Treat one of important tool of human body diseases.
Need to pass through endoscope lens insertion human body intracavitary in camera technique general during ESS is carried out
Sight glass lens shooting to intracavity figure as real-time display is on special monitor, doctor transports according to the image shown on monitor
Performed the operation with special operating theater instruments.
The temperature of camera lens and operating room room temperature are close about 20 DEG C to 25 DEG C before endoscope insertion chamber.When endoscope inserts
Endoscope lens can be warming up to 37 DEG C of human temperature gradually and mirror occur due to Water vapor condensation during camera lens heats up after chamber
The phenomenon of head mould paste, so as to cause the fogging image for photographing monitor to influence the operation technique of doctor.
For problem above, clinically universal operation is the doctor that performed the operation when endoscope lens haze and influence doctor's sight
Raw or nurse extracts endoscope out from the patient, with the hot physiology salt having one's hair waved camera lens for filling 70 1 80 DEG C, is then peeped again by interior
Mirror reinserts in patient body.Less effective after the good of the antifog effect in 30min of this method but 30min, majority need again or
Anti-fogging measure, operating time is repeated several times>During 30min, with preheating method, centre needs to change hot salt brine, and operation sequence is increased same
When also increase the possibility of pollution, it is also possible to damage camera lens.Layer protecting film can be formed using PVP-I method, weakens mist
Gas is to the adhesive force of camera lens, so as to play antifogging action, although salt solution, which will not occur, spreads out pollution and camera lens tipping damaged condition,
It is good compared with Traditional Method, but add because of the excessive and potential opportunities for contamination of surgical supplies, operation consuming cost is added, causes wave
Take, while polluted there is also increase during secondary or multiplicating anti-fogging measure, the probability of damage camera lens.And it can so extend hand
The art time, reduce the efficiency of operation.
Find that the utility model that China Patent Publication No. is CN106108958A discloses through the literature search to prior art
A kind of clipping endoscope lens temperature control anti-smog device includes clamping device, heating system, shell and inwall packing ring.It is this
Device can cause endoscope lens to have good heating and heat insulation effect, can effectively reduce camera lens in ESS
Condensation phenomenon.The weak point of the device is that the clamping of endoscope perioperatively needs to dismantle, and the device is disposable dress in addition
Put and be also the increase in new operation consumptive material, operation benefit rate does not significantly improve.
TiO2Coating R.Wang in 1997 is found that titanium dioxide (TiO2) film has a Superhydrophilic phenomenon, i.e., water with
TiO2Semiconductor surface contacts, and after by ultraviolet light, contact angle diminishes rapidly, and finally reaching 0 °, (i.e. water droplet soaks completely
Enter TiO2Film surface), here it is TiO2Super hydrophilic characteristic.Stop illumination by TiO2Film places a period of time in the dark,
Contact angle can incrementally increase, and be restored to hydrophobic state, if super hydrophilic state can be become again through irradiation again.This characteristic makes thin
Film has the functions such as self-cleaning decontamination, easy cleaning, water-mist-proof.
Glass surface plates TiO2After film under light illumination (no matter cold light source or thermal light source), surface has height
Water-wet behavior, so as to have antifog and self-cleaning function.When water is in TiO2The contact angle of film surface has height when being less than 15 °
Mobility；There is automatically cleaning effect when contact angle is less than 10 °；There is antifog effect during less than 7 °, and contact angle is smaller antifog
Effect is better.It is this method good antifogging effect, wear-resisting.TiO2Photochemical catalyst may also be used for sterilizing, the preparation such as KikuchiY
TiO2, Escherichia coli are killed, are worked well.In order to kill and suppress the growth of bacterium, people develop TiO2Antibiotic paint.
TiO2The preparation of coating is more ripe, including electrostatic self-assembled technology, micro plasma oxidation, liquid phase deposition, molten
The gel method of glue one, chemical vapour deposition technique, magnetron sputtering method etc., wherein the most commonly used with sol-gel method.Whether TiO2
Self-cleaning film, TiO2Hydrophilic antifogging coating or TiO2Anti- TiO2Bacterium film has corresponding preparation method.
For prior art literature search find China Patent Publication No. be the B of CN 102718410 patent of invention just
Disclose a kind of preparation method of self-cleaning anti-fog coat film.Self-cleaning fog film prepared by the invention has good
Photocatalytic activity and super hydrophilicity, water can be effectively reduced on surface.The coating can further improve the water of film surface
Wettability so as to make up the rise of contact angle under night non-illuminated conditions make film all the time can apparent contact angle condition enough remain super
Hydrophilicity.
The content of the invention
The purpose of this utility model is to provide a kind of endoscope head with anti-smog device, utilizes TiO2Characteristic, in thing
TiO is set on lens head and the clear glass minute surface of illumination camera lens front end2Coating, reach work antifog in surgical procedure
With the condensation phenomenon of camera lens effectively in reduction ESS.TiO simultaneously2Antifogging coating has automatically cleaning, not sterilizing, shadow
Ring the effect that light transmittance even improves light transmittance；In addition, the anti-smog device enter body cavities will not to human body produce harm with
And endoscope lens normal service life is not interfered with.
To achieve the above object, technical solution of the present utility model is：A kind of endoscope head with anti-smog device,
Including outside protective pipe, it is characterised in that：Teleflex 2, lighting fiber 4, the first steel wire 3, the second steel are provided with the outside protective pipe 1
Silk 11, image transmission optical fibre 6 and mechanical passage 8, form illumination passage 9 between the first steel wire 3 and the side inwall of teleflex 2, the illumination is led to
