Dental esthetics optical lens surface, oral cavity demisterTechnical field
The present invention relates to the device demister of the lens surface mist on oral cavity and dentistry microsurgery optical microphotograph lens head, refer to especially and a kind ofly automatically can remove glass surface in the space of oral cavity and microscope camera lens, optical microscope picture frame of performing the operation in time and stick demister---the demister in optical microscope mirror of fog.
Background technology
When current oral cavity and dentistry microsurgery, all tightly according to operating doctor side by the hand-held air blowing capsule of nurse, nurse's order and produce aerosol or doctor's signal, nurse pick up quickly air blowing capsule facing to camera lens surface puff and blow blow several under, fog is removed strive for that continuing operation goes down as possible.
Prior art utilizes special people ﹙ nurse or doctor raw ﹚ cost of labor is high, repeatedly low, the oral cavity humidity of air blowing demisting efficiency increasing except fog effect worse and worse, air bag air blowing air-flow be that point-like or jet-like spray and cause air-flow stationarity poor, thus add operating difficulty-patient's misery-medical treatment cost and affect oral cavity and dentistry microsurgery effect.
Summary of the invention
The technical problem to be solved in the present invention overcomes dependence special messenger hand-held air bag air blowing demist difficulty defect when being just the demist of operating microscope optical lens, there is provided one to have automatic defogging utensil to replace artificial hand-held air bag demist operator scheme, utilize gases at high pressure to remove optical lens surface fog by automatic air blowing demister.Demister mechanism of the present invention, mirror frame ﹙ 1 ﹚ mono-week air inlet pore ﹙ 7 ﹚ pressing circle ﹙ 3 ﹚ to form with close envelope circle ﹙ 2 ﹚ by optical lens large thing mirror frame ﹙ 1 ﹚, close envelope is connected gas groove ﹙ 4 ﹚, high pressure draught can be sprayed with regard to gas centripetal air blowing Kong ﹙ 6 ﹚ inside Qi Cao ﹙ 4 ﹚, utilize gases at high pressure to remove the modularity parts of the sticky mist in Guang Jing Pian ﹙ 5 ﹚ surface.Wherein large Wu Jing Kuang ﹙ 1 ﹚, Mi seal Ya Quan ﹙ 3 ﹚ and Mi Feng Quan ﹙ 2 ﹚ formation, large Wu Jing Kuang ﹙ 1 ﹚ mono-week Qi Cao ﹙ 4 ﹚ high pressurized gas gas, clean, the uniform gas that utilize local operating room air compressor-electromagnetic valve automatically to produce, surgical operation can be equipped with by demister gauge tap case button according to operational circumstances, the demister automatic feeding gas realizing operating microscope optical lens surface is eyeglass demist, and Optics in Microscope mirror oral cavity and dental operation visualized operation definition have had guarantee.
The demister performance technologies index on operating microscope optical lens surface of the present invention is as follows:
| Sequence number | Project | Index |
| 1 | Maximum overall dimensions | Φ65×33.5﹙mm﹚ |
| 2 | 360 degree, large objective lens frame pore is evenly distributed 60 degree, 10 inclination angles through hole | Through-hole aperture Φ 1.5 ﹙ mm ﹚ |
| 3 | Allow ambient temperature | ≥＋5℃ |
The demister on operating microscope optical lens surface of the present invention, automatic defogging mode is needed to prepare to replace manual operation mode operation Optics in Microscope camera lens when being applicable to oral cavity and dental operation, be equipped with electrothermal semiconductor to supply electric ﹙ PTC ﹚ thermal source, be equipped with the prior art control utensils such as sequence controller ﹙ PLC ﹚ circuit power of can programming, realize the optical lens surface demister automatically controlling air pump, Qi Wen ﹙ Wen number of degrees Xian ﹚, air pressure, warm air flow, can convenient, succinct, removal picture frame inner lens surface fog.
The demister on operating microscope optical lens surface of the present invention, not only can make optical lens surface demister at the medical and health sector such as oral cavity and dentistry for the surface demist of oral cavity optical lens, also derive the surface demist of the optics thermometric camera lens of metal smelting liquid measure more than thousand degree high-temperature liquid surface temperatures, also derive the picture frame inner lens surface that workina ocular is equipped with to chemical defense force's clothing and to meet an urgent need demist, only this is obvious, the demister technology on operating microscope optical lens surface of the present invention and goods, have broad prospect of application.
Accompanying drawing explanation
Below in conjunction with accompanying drawing to further instruction of the present invention:
Fig. 1 is the demister structural representation on this operating microscope optical lens surface
Fig. 2 is the demister large object lens picture frame component diagram on this operating microscope optical lens surface
With reference to Fig. 1, Guang Jing Pian ﹙ 5 ﹚ that the demister on operating microscope optical lens surface of the present invention is sealed under Ya Quan ﹙ 3 ﹚ and Mi Feng Quan ﹙ 2 ﹚ and Mi Feng Quan ﹙ 2 ﹚ trim ring by large Wu Jing Kuang ﹙ 1 ﹚, Mi is formed.Inside preparation air inlet pore ﹙ 7 ﹚ of the demister on operating microscope optical lens surface of the present invention and gas groove ﹙ 4 ﹚, centripetal air blowing hole ﹙ 6 ﹚ is that compressed air produces power gas feed track system, belongs to processes figure.
With reference to Fig. 2, the demister on operating microscope optical lens surface of the present invention, centripetal air blowing hole ﹙ 6 ﹚ inside workpiece large thing mirror frame ﹙ 1 ﹚ air inlet pore ﹙ 7 ﹚ and gas groove ﹙ 4 ﹚, processing needs to reach dimensional accuracy.
Detailed description of the invention
Be below that of the present invention fitting executes example, reality of the present invention uses to be not limited to fit executes example.
the suitable demister executing example 1 operating microscope optical lens surface
Adopt the demister with the operating microscope optical lens surface of structure of the present invention, Guang Jing Pian ﹙ 5 ﹚ sealed under Ya Quan ﹙ 3 ﹚ and Mi Feng Quan ﹙ 2 ﹚ and Mi Feng Quan ﹙ 2 ﹚ trim ring by operating microscope optical lens large Wu Jing Kuang ﹙ 1 ﹚, Mi forms, wherein large thing mirror frame ﹙ 1 ﹚ and the polish of close envelope pressure circle ﹙ 3 ﹚ application cast aluminium alloy are made, are coordinated with food stage rubber glue close envelope circle ﹙ 2 ﹚, and the demister assembling Optics in Microscope camera lens surface meets process specifications.
The demister performance technologies index on operating microscope optical lens surface is as follows:
| Sequence number | Project | Index |
| 1 | Maximum overall dimensions | Φ65×33.5﹙mm﹚ |
| 2 | 360 degree, large objective lens frame pore is evenly distributed 60 degree, 10 inclination angles through hole | Through-hole aperture Φ 1.5 ﹙ mm ﹚ |
| 3 | Allow ambient temperature | ≥＋5℃ |
Operating microscope optical lens surface of the present invention demister, use when direct oral cavity and dental clinic microsurgery, user reaction is good, thinks and has met the instructions for use of operating microscope optical lens clinical demist effect by operating microscope optical lens of the present invention surface demister.
