[0027] In order to more clearly and completely illustrate the technical scheme of the present application, the present application will be further described below in combination with the drawings.

[0028] Please refer to Figures 1-3 ​The utility model provides a femtosecond preoperative training appearance, including main part 1, first pusher 2, main part 1 is the body of femtosecond preoperative training appearance, and the side of main part 1 is equipped with mobile support frame 11, and first pusher 2 is horizontally fixedly connected on mobile support frame 11, and first pusher 2 is electrically connected with main part 1, and first pusher 2 is used to drive main part 1 to carry out horizontal displacement, and main part 1 controls femtosecond laser emission simulation equipment, and simultaneously presents two kinds of treatment scene of full femtosecond, half femtosecond laser by internal display respectively.

[0029] In the embodiment, the first pusher 2 is horizontally installed on the mobile support frame 11 on the main body 1. The pushing end of the first pusher 2 needs to be fixed on the seat on which the patient lies or sits, and the seat is fixed on the ground and does not move. After the main body 1 completes the training on one eye of the patient, the first pusher 2 pushes the mobile support frame 11 to move a preset distance, so that the main body 1 moves a preset distance laterally to switch to above the other eye of the patient and perform training. For example, the patient first trains the right eye. After the right eye training is completed, the first pusher 2 pushes the mobile support frame 11 to move to the left side, so that the main body 1 moves a preset position to the left side. The preset distance can be adjusted by an external controller on the first pusher 2. The whole process does not need the patient to adjust the position by standing up, which is convenient and fast.

[0030] In summary, the femtosecond preoperative training appearance can automatically switch the left and right eye training of the patient without the patient moving by himself.

[0031] In the embodiment, the first pusher 2 includes a first driving device 21, a fixed cylinder 22, and a push rod 23. The first driving device 21 is a stepper motor. The first driving device 21 is fixedly connected to one side of the mobile support frame 11. The fixed cylinder 22 is fixedly connected to the other side of the mobile support frame 11. The push rod 23 is slidably connected with the fixed cylinder 22 and is in transmission connection with the rotating shaft of the first driving device 21. The rotating shaft of the first driving device 21 is a lead screw. The lead screw is in screw transmission connection with the push rod 23. When the first pusher 2 pushes, the first driving device 21 rotates forward for a preset time. Since the push rod 23 is fixed on the seat on which the patient lies or sits, under the action of force and reaction force, the push rod 23 does not move, the fixed cylinder 22 slides relative to the push rod 23, and the mobile support frame 11 moves backward to drive the main body 1 to move. When the first driving device 21 rotates reversely, the push rod 23 is pulled to move forward.

[0032] In the embodiment, the rotating shaft of the first driving device 21 penetrates the mobile support frame 11 and extends into the fixed cylinder 22. In order to save the space occupied by the first driving device 21, the rotating shaft of the first driving device 21 penetrates the mobile support frame 11.

[0033] In this embodiment, one end of the push rod 23 is provided with a flange 231 for external connection. Before use, the flange 231 needs to be fixed to one side of the seat where the patient is lying down or supine, so that the push rod 23 is connected to the seat as one unit.

[0034] In this embodiment, the main body 1 includes a housing 12, a circuit board 13, a second pushing device 14, a display 15, and a cone lens barrel 16. One end of the second pushing device 14 is fixedly connected to the inside of the housing 12, and the other end of the second pushing device 14 is fixedly connected to the back of the display 15. One end of the cone lens barrel 16 is fixedly connected to the display 15 and aligned with the playback surface of the display 15, while the other end of the cone lens barrel 16 protrudes from the outside of the housing 12. The circuit board 13 is fixedly connected to the inside of the housing 12 and electrically connected to the second pushing device 14 and the display 15 respectively. The circuit board 13 is used to issue corresponding operating commands to the second pushing device 14 and the display 15 respectively. The second pushing device 14 has the same structure as the first pushing device 2, both using a motor to drive a lead screw to rotate and drive a push rod to slide, thereby achieving the purpose of lifting and lowering. When training one eye of a patient, the second pushing device 14... The device 14 lowers the display 15 and the cone tube 16 together. Specifically, during femtosecond laser surgery and corneal flap creation using femtosecond laser, the second pushing device 14 controls the cone tube 16 to be near the eyeball. During femtosecond excimer laser ablation of the corneal stroma, the second pushing device 14 retracts the cone tube 16 into the main body 1. The cone tube 16 stops after descending to a preset height above the patient's eyes. The patient can view the display 15 through the cone tube 16, and the display 15 plays a real-life image of the surgery for the patient to watch, thus achieving a training effect. That is, the femtosecond preoperative training device can control the extension and retraction of the cone tube 16 by the second pushing device 14, while the display 15 shows the images of femtosecond laser and femtosecond laser surgery. In addition, it can automatically switch the patient's left and right eye training to achieve the purpose of femtosecond laser training and femtosecond laser training for each eye separately.

[0035] In this embodiment, the conopod 16 is provided with a viewing window 161, which is aligned with the playback surface of the display 15. The viewing window 161 is provided with a convex lens, which can appropriately magnify the image of the display 15, so that the patient can experience a more realistic surgical process.

[0036] In this embodiment, the main body 1 also includes a distance sensor 17, which is fixedly connected to one side of the cone tube 16 and electrically connected to the circuit board 13. The distance sensor 17 is an infrared distance sensor. During the process of the second pushing device 14 driving the display 15 and the cone tube 16 to descend together, the distance sensor 17 detects the height of the bottom of the cone tube 16 and the patient's eye, and then controls the descent height. Generally speaking, the cone tube 16 needs to be lowered to a height of 2cm from the patient's eye.

[0037] In this embodiment, the main body 1 also includes a ring light 18, which is fixedly connected to the surface of the outer shell 12 and arranged around the outer periphery of the conograph tube 16. The ring light 18 is electrically connected to the circuit board 13 through conductive wires. During training, since the ring light 18 also illuminates the patient during the operation, it is also necessary to set up a ring light 18 here to provide illumination and restore the surgical scene.

[0038] In this embodiment, the main body 1 also includes a rotating device 19, which is fixedly connected inside the outer casing 12 and electrically connected to the circuit board 13. The rotating end of the rotating device 19 is fixedly connected to one end of the movable support frame 11. Before the patient lies supine or on the chair, i.e. before training, the main body 1 does not rotate to the top of the chair, but makes room for the patient to sit on the chair. After the patient sits on the chair and lies supine or on the chair, the rotating device 19 rotates. Since the movable support frame 11 is relatively fixed, the main body 1 rotates at a preset angle during rotation, so that the main body 1 rotates to the top of the patient and is arranged horizontally.

[0039] In this embodiment, the bottom of the movable support frame 11 is provided with a sliding base 111 for sliding on the ground. Multiple wheels are provided under the sliding base 111 for smooth sliding. After the first pushing device 2 pushes, the sliding base 111 slides relative to the ground to displace the main body 1.

[0040] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
