It is convenient to receive adjust instruction, temperature sensor and display and operator electrical communication, facilitate real-time display to open the temperature of eyelid ring, control
Coremaking piece is connected with telescopic device, realizes the control to telescopic device；Connected with pressure sensor, it is convenient to receive pressure signal；
Connected with display and controller, it is convenient to receive adjust instruction；Electrical pressure sensor and display and controller electrical communication, it is convenient
Real-time display opens the pressure of eyelid ring.The specific connection relation of the present embodiment is as shown in Figure 4.
Certainly, when it is implemented, should also there is prior art motor-operated control valve to carry out each element such as telescopic device, power supply etc.
Switch control, here just not tough state.
Pressure adjusts process：
By opened on being fixed on eyelid ring and under drive the pressure sensor on eyelid ring contact reached into display and controller,
Again by display and the real-time display of controller, if pressure value is too high or too low, when need to adjust, operator sends adjust instruction,
After control chip receives instruction, processing signal is sent to telescopic device, telescopic device in flexible adjustment by opening eyelid ring with
The distance between eyelid ring is opened, so that the contact of itself and patient's eyelid is adjusted, so as to accurately control expansionary force, both
Ensure not damage eyelid, also ensure that the opening of eyelid is horizontal, so as to mitigate the psychological burden of patient, strengthen the confidence to operation,
Actively operation is coordinated to reduce operation risk.
Temperature adjustment process：
By opened on being fixed on eyelid ring and under drive the temperature sensor on eyelid ring real time temperature reached into display and operator,
Again by the real-time display of display and operator for operator's judgement, if temperature value is too low when need to adjust, operator sends heating
Instruction, after process chip receives instruction, communications signals are sent to heating power supply, it is provided heating electric energy to adding thermal resistance,
With the rise of temperature, temperature sensor constantly beams back temperature value, and operator works as arrival by display and operator Real Time Observation
During predetermined value, process chip sends cut-off signal to heating power supply, and adding thermal resistance is stopped, and makes eye speculum keep human body suitable
Temperature, when opening eyelid ring and being contacted with eye, do not stimulate human body, patient can be very comfortable, so as to mitigate the psychological burden of patient, strengthens
To the confidence of operation, actively coordinate operation is final to reduce operation risk.
What deserves to be explained is the present embodiment is integrated into processor to reduce component count, by process chip and control chip
12nd, display and operator and display and controller are integrated into operator 13, while temperature and pressure are controlled, and make eye speculum
It is simple in structure, volume smaller, easy to use and storage.
The shade of the present embodiment to be made of light screening material and corrugated shading square 8, meanwhile, shading
The gauffer 3 of square is arranged in parallel, and is provided with sleeve along two sides of the width of gauffer, and sleeve loads onto out eyelid for set
Ring opens eyelid ring with.In use, eyelid ring can be quickly charged with open with sleeve opens eyelid ring with, operation is very simple, since gauffer is put down
Row set, and along its width set sleeve, therefore, as open eyelid operation when, the gauffer of shading square is straightened, without quilt
Damage.By shade to above open eyelid ring and under open the region between eyelid ring and block, the strong light of operating lamp can be avoided to suffering from
The irradiation of person's eyes, so that the visual fatigue of reduction of patient, mitigates the psychological burden of patient, reduce operation risk.
In the present embodiment, telescopic device is electric pushrod 6, can be by fixing a driving battery in fixed arm, you can
Realize electric operating.Relative to hydraulic cylinder and cylinder, its is simple in structure.
It is well known that human body face is irregular, spatially there are difference in height, if opening eyelid device is provided only on one
In a plane, then there can be the problem of interfering, it is necessary to select special angle to go to operate due to eyelid and forehead and bridge of the nose injustice,
This can influence the efficiency of operation, therefore, the rotating arm of the present embodiment and on open between eyelid ring and rotating arm and under open between eyelid ring
Be both provided with linking arm 7, linking arm is vertical with rotating arm or is obliquely installed, so make rotating arm and above open eyelid ring and under open eyelid ring
Between there are a difference in height, make driving device and above open eyelid ring and under open eyelid ring not in a plane, as shown in Figure 1, in this way,
Can carry out out in any direction eyelid operation, easy to improve procedure efficiency, preferably, difference in height can reach when being 5-30mm compared with
Good effect.
In the present embodiment, insulating layer 16 is provided between " C " shape bend pipe and adding thermal resistance, safety can be increased by insulating layer
Property.
In the present embodiment, " C " shape bend pipe is made of elastoplastic, and with insulating layer and adding thermal resistance integrated injection molding into
Type, in this way, when eyelid ring is opened in making, can disposably machine, and save production cost, meanwhile, the relative position between three
It will not change, improve stability and reliability.
In the present embodiment, two pressure sensors be separately fixed at out eyelid ring and under open in the middle part of " C " shape of eyelid ring, make pressure
Force snesor is located at the highest and extreme lower position of eyelid, and pressure value is maximum at this time, and measured value is easier to reflect contact.Into one
Step, pressure sensor is capacitance pressure transducer, and sensor is flake structure, beneficial to a pottery of fixation, such as Germany's production
Porcelain capacitance pressure transducer, model CCPS 18, its thickness are only a few mm, it is convenient with above open eyelid ring and under open eyelid ring and fix,
It can avoid the stimulation to human eye.
Second embodiment
As shown in figure 5, the present embodiment shade unlike first embodiment is elastic membrane 9, elastic membrane is provided with
Shading coating, is provided with sleeve on two edges of elastic membrane, sleeve for set load onto out eyelid ring and under open eyelid ring.Open eyelid operation
When, elastic membrane by elasticity with above open eyelid ring and under open eyelid ring and be flared out, be covered with out eyelid ring and under open area between eyelid ring
Domain, forms operation light and blocks, protect patient's eye.
Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with
The present invention is described in detail in good embodiment, it will be understood by those of ordinary skill in the art that, can be to the skill of the present invention
Art scheme technical scheme is modified or replaced equivalently, without departing from the objective and scope of technical solution of the present invention, it should all cover at this
Among the right of invention.
