Focusing, namely, two eyes of a patient are simultaneously opened, one eye is covered by medical sterile cloth, a medical staff holds the hand-held handle 1, so that the hand-held handle 1 is kept in a vertical state, one end of the hand-held handle 1 provided with a light component faces the patient, one end of the hand-held handle 1 provided with the light component is arranged above the uncovered eye of the patient for about 5cm and gradually approaches the eyes of the patient, and the eyes of the patient follow the center of a light source;
e. The simulated negative pressure suction stage comprises the steps of pressing a master control switch 12 when the edge of a silica gel eyeshade 8 is completely attached to eyes, enabling an annular lamp module 2 to work together with a punctiform lamp module 3, enabling the punctiform lamp module 3 to emit flashing green light while enabling a patient to stare the flashing green light, keeping the eyes at a fixed position after locating a center point, enabling a timer 10 to start working through a timing switch 11 when the eyes of the patient are stable, timing for 30 seconds, and simulating the negative pressure suction stage in the ophthalmic operation process, wherein a lamplight state diagram of a lamplight assembly is shown in fig. 6 when the negative pressure suction stage is simulated;
After the simulation of the negative pressure suction stage in the ophthalmic operation process is completed, the hand-held handle 1 is lifted, the silica gel eyeshade 8 is separated from eyes of a patient to a position about 30cm away, the main control switch 12 is pressed, the round lamp module 4 starts to work, the round lamp module 4 emits strong white light, the patient looks at a light source, the time is 30 seconds, the simulation of the cornea taking stage in the ophthalmic operation process is carried out, and a lamplight state diagram of a lamplight assembly in the simulation of the cornea taking stage is shown in fig. 7;
g, after simulation of the corneal lens taking stage in the ophthalmic operation process is completed, pre-operation scene simulation training is completed, and the master control switch 12 is closed.
In the preoperative scene simulation training process, the eye position of the patient can be observed through the silica gel eyeshade 8, the change of the eye position of the patient is recorded in real time by the miniature industrial camera 6, and the eye position of the patient needs to be observed to be moved or not during simulation, so that the patient can blink occasionally but can not have eye displacement.
Wherein, the first time presses the master control, the annular lamp module 2 begins to work, and simultaneously the miniature industrial camera 6 begins to work, the second time presses the master control switch 12, the punctiform lamp module 3 works together with the annular lamp module 2, the miniature industrial camera 6 continues to work, the third time presses the master control switch 12, the punctiform lamp module 3 closes with the annular lamp module 2, the circular lamp module 4 begins to work, the miniature industrial camera 6 continues to work, the fourth time presses the master control switch 12, the circular lamp module 4 closes, the miniature industrial camera 6 closes, the device is in the closed state.
After the evaluation simulation of one eye of the patient is completed, the eye after the evaluation simulation is covered by the medical sterile cloth, and the evaluation simulation is performed on the eye of the patient which is not subjected to the evaluation simulation, wherein the medical sterile cloth is used for shading light, so that the influence of light on the evaluation simulation process is avoided.
In the simulated negative pressure suction stage, when a patient is difficult to focus on the flickering green light emitted by the punctiform lamp module 3, the auxiliary calibration mechanism assists the patient to find the flickering green light emitted by the punctiform lamp module 3 and guide the patient to follow the flickering green light emitted by the punctiform lamp module 3 to reset to the central point of the lamplight assembly, and as the silica gel eyeshade 8 has limited inner space and limited movement position of the pupil of the patient, the requirement of guiding the sight of the patient can be met by fine adjustment of the punctiform lamp module 3 through the micro calibration steering engine 16.
The standard head position is that the forehead and the mandible of a patient are kept on the same plane and parallel to the horizontal plane, the vertex of the cornea is vertical to the ground, and the patient can blink occasionally in the simulation process, but the head and the eye position are prevented from being changed, namely, the rotation, the offset and the like of the eyeball cannot be changed.
Working principle:
the lamplight conversion of each lamplight module in the lamplight assembly is used for simulating lamplight conversion in the operation process, so that scene simulation training is carried out on a patient before the operation is carried out, the patient can truly experience the situation in the operation before the operation, in the evaluation simulation process, the camera assembly is used for recording blink, eye movement, eye position and other data of the patient, the data are uploaded to a computer terminal for storage through the wireless transmission module 7 or the data transmission interface 14, the intraoperative coordination condition of the patient is mastered, basis is provided for guiding the patient to smoothly cooperate with the operation, and the duration of each stage in the simulation process can be accurately controlled through the timing assembly.
The invention has the advantages of simple structure, small volume, easy operation and convenient holding, can simulate the lamplight transformation scene in the operation process, thereby leading the patient to truly experience the situation in the operation before the operation, grasping the matching key points in the operation, relieving the stress and anxiety of the patient, reducing the accidents in the operation, recording the blink and eye movement data of the patient through the camera shooting assembly, providing reference for the operation process, ensuring the detachable replacement of the eye shield assembly, facilitating the simulation use requirements of different patients, being convenient for disinfection, being reusable, being economical and practical.
The foregoing describes one embodiment of the present invention in detail, but the disclosure is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. All equivalent changes and modifications within the scope of the present invention are intended to be covered by the present invention.
