Description

Technical Field

[0001] The present invention relates to the technical field of preoperative simulation evaluation devices, and in particular to a preoperative scenario simulation training device and a simulation method thereof. Background Art

[0002] In the prior art, when an eye surgery is performed, the patient is unfamiliar with the operating room environment before the operation, and during the operation, the light source and lighting status of the operating room will change at different stages of the operation. These unknown situational factors before the operation will cause discomfort to the patient during the operation and easily cause negative emotions such as anxiety and uneasiness in the patient before the operation, which may have an adverse effect on the operation process. In addition, during the operation, the patient is required to cooperate with the doctor's instructions to perform corresponding actions. For example, when flushing the eyes, the patient is asked to rotate the eyeball up and down, left and right, keep the eyeball still and stare at the bright light. Most patients will feel nervous during the eye surgery, which may cause eye tremors and inability to cooperate with the doctor's instructions as required by the doctor, thereby affecting the progress of the operation. Therefore, it is necessary to let the patient understand the lighting change scenario during the operation before the operation, so that the patient can truly experience the situation during the operation before the operation. However, the operating room resources are relatively tight, and it is impossible to provide patients with scenario simulation through the operating room for reasons such as economy and convenience. Therefore, the existing medical conditions cannot meet the needs of patients for lighting scenario simulation before the operation.

[0044] Among them, the device can work offline, that is, through the oral instructions of medical staff, the patient can cooperate in the preoperative scenario simulation.

[0045] A simulation method of a preoperative scenario simulation training device comprises the following steps:

[0046] a. Disinfection: disinfect the end of the hand-held handle 1 connected to the silicone eye mask 8 and the silicone eye mask 8, and connect the silicone eye mask 8 to the end of the hand-held handle 1 provided with the light assembly through the eye mask slot 9;

[0047] b. Body position: Let the patient lie flat on the examination bed or let the patient sit upright with the head tilted back;

[0048] c. Debugging: Turn on the master control switch 12, the ring light module 2 starts working and the miniature industrial camera 6 starts working at the same time. The ring light module 2 emits a ring-shaped white light, and the miniature industrial camera 6 transmits data with the computer terminal through the wireless transmission module 7 or the data transmission interface 14. The light intensity of the ring light module 2 is adjusted through the light source brightness adjustment switch 5, and the camera interface of the miniature industrial camera 6 is debugged through the computer terminal;

[0049] d. Focusing: Let the patient open both eyes at the same time, cover one of the eyes with a medical sterile cloth, and the medical staff hold the hand-held handle 1 to keep the hand-held handle 1 in a vertical state, and make the end of the hand-held handle 1 with the light component face the patient, and place the end of the hand-held handle 1 with the light component about 5 cm above the uncovered eye of the patient, gradually approaching the patient's eye, and let the patient's eye follow the center of the light source. The light state of the light component in the focusing state of the present invention is as shown in the figure Figure 5 As shown;

[0050] e. Simulating negative pressure suction stage: When the edge of the silicone eye mask 8 is completely in contact with the eye, the main control switch 12 is pressed, and the annular light module 2 and the dot light module 3 work together. The annular light module 2 emits annular white light while the dot light module 3 emits flashing green light. The patient is asked to stare at the flashing green light and keep the eye position still after finding the center point. When the patient's eye position is stable, the timer 10 is started by the timing switch 11, and the timing is 30 seconds to simulate the negative pressure suction stage during the ophthalmic surgery. The lighting state of the lighting assembly during the simulated negative pressure suction stage of the present invention is shown in the figure below. Figure 6 As shown;

[0051] f: Simulation of corneal lens removal stage: After completing the simulation of the negative pressure suction stage during the ophthalmic surgery, lift the hand-held handle 1 to separate the silicone eye mask 8 from the patient's eyes to a position about 30 cm apart, press the master control switch 12, and the circular light module 4 starts to work. The circular light module 4 emits a strong white light, and the patient is asked to stare at the light source. The timing is 30 seconds to simulate the corneal lens removal stage during the ophthalmic surgery. The lighting state of the lighting assembly when simulating the corneal lens removal stage of the present invention is shown in the figure below. Figure 7 As shown;

[0052] g: After completing the simulation of the corneal lens removal stage during the ophthalmic surgery and completing the preoperative scenario simulation training, turn off the main control switch 12.

[0053] During the preoperative scenario simulation training, the patient's eye position can be observed through the silicone eye mask 8, and the miniature industrial camera 6 records the changes in the patient's eye position in real time. During the simulation, it is necessary to pay attention to whether the patient's eye position moves. Occasionally blinking is allowed, but the eyes cannot shift.

[0054] Among them, when the master control is pressed for the first time, the ring light module 2 starts working, and the micro industrial camera 6 starts working at the same time. When the master control switch 12 is pressed for the second time, the point light module 3 and the ring light module 2 work together, and the micro industrial camera 6 continues to work. When the master control switch 12 is pressed for the third time, the point light module 3 and the ring light module 2 are turned off, the circular light module 4 starts working, and the micro industrial camera 6 continues to work. When the master control switch 12 is pressed for the fourth time, the circular light module 4 is turned off, the micro industrial camera 6 is turned off, and the device is in the off state.

[0055] After completing the evaluation simulation for one eye of the patient, the eye that has completed the evaluation simulation can be covered with a medical sterile cloth, and the patient's eye that has not undergone the evaluation simulation can be subjected to an evaluation simulation. The medical sterile cloth is used to block light to prevent light from affecting the evaluation simulation process.

[0056] Among them, during the simulated negative pressure suction stage, when the patient has difficulty focusing on the flashing green light emitted by the point-shaped light module 3, the auxiliary calibration mechanism is used to assist the patient to find the flashing green light emitted by the point-shaped light module 3 and guide the patient to follow the flashing green light emitted by the point-shaped light module 3 to reset to the center point of the light assembly. Since the internal space of the silicone eye mask 8 is limited and the position of the patient's pupil movement is limited, the micro-calibration servo 16 is used to fine-tune the point-shaped light module 3 to meet the requirement of guiding the patient's line of sight.

[0057] Among them, the standard head position is that the patient's forehead and mandible remain in the same plane and parallel to the horizontal plane, the corneal apex is perpendicular to the ground, and during the simulation, the patient can blink occasionally, but changes in the head and eye position must be avoided, that is, rotation, deviation and other position changes of the eyeballs are not allowed to occur.

[0058] Working principle:

[0059] By simulating the lighting changes during surgery through the lighting changes of each lighting module in the lighting component, the patient can be trained in scenario simulation before the surgery, so that the patient can truly experience the situation during surgery before the surgery. In the evaluation simulation process, the patient's blinking, eye movement, eye position and other data are recorded by the camera component, and the data is uploaded to the computer terminal for storage through the wireless transmission module 7 or the data transmission interface 14, so as to understand the patient's cooperation during the surgery and provide a basis for guiding the patient to cooperate smoothly with the surgery. The timing component can accurately control the duration of each stage in the simulation process.

[0060] The beneficial effects of the present invention are simple structure, small size, easy operation and convenient holding. It can simulate the lighting change scene during the operation, so that the patient can truly experience the situation during the operation before the operation, master the key points of cooperation during the operation, relieve the patient's tension and anxiety, and reduce intraoperative accidents. The camera component can record the patient's blinking and eye movement data, thereby providing a reference for the operation process. The eye mask component is detachable and replaceable, which is convenient for the simulation use needs of different patients. It is easy to disinfect, reusable, and economical and practical.

[0061] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
