Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a full femtosecond laser refractive surgery simulation gaze trainer. Background Art

[0002] All-femtosecond laser refractive surgery is a surgery that uses laser technology to correct the refractive power of the eye. The surgery uses a femtosecond laser to make micro-cuts on the surface of the cornea to change the curvature of the cornea so that the light can be correctly focused on the retina to achieve the purpose of correcting vision.

[0003] During surgery, when the laser scans close to the pupil, the fixation point will become blurred or disappear. The human eye will move involuntarily for a moment due to searching for the fixation point or nervousness, which will lead to reduced laser accuracy, or surgical negative pressure loss and interruption of the surgery, thus affecting the quality of the surgery. Therefore, it is necessary to develop a preoperative simulated fixation trainer to introduce the real situation during the surgery into the simulation training. After training, the patient can enter the operating room for surgery to ensure the smooth progress of the surgery.

[0004] For example, the Chinese patent with the publication number CN215916108U discloses a preoperative simulation training device for all-femtosecond laser myopia surgery, which includes a column, a latex lamp, a lateral adjustment mechanism, and a height adjustment mechanism. The lower end of the column is provided with a holder for fixing the preoperative simulation training device for all-femtosecond laser myopia surgery on the examination and treatment bed. The upper end of the column is covered with a sleeve with adjustable height. One end of the lateral adjustment mechanism is fixed on the sleeve, so that the height adjustment mechanism installed above the column through the sleeve is installed on the other end of the lateral adjustment mechanism. The latex lamp is arranged below the height adjustment mechanism. The height adjustment mechanism is used to adjust the height of the latex lamp, and the lateral adjustment mechanism is used to adjust the lateral position of the height adjustment mechanism and indirectly adjust the lateral position of the latex lamp. It simulates the process of all-femtosecond surgery, allowing patients to understand the process of all-femtosecond surgery to improve the cooperation of patients' intraoperative eye position activities.

[0005] However, the above-mentioned all-femtosecond laser myopia surgery preoperative simulation training device has some shortcomings in actual use:

[0006] 1. The above device simulates the process of all-femtosecond surgery, allowing patients to understand the process of all-femtosecond surgery to improve the patient's cooperation in eye movement during the operation. However, in actual operation, when the laser scans close to the pupil position, the gaze point will become blurred or disappear. The above device cannot simulate the blurred feeling in the patient's eyes. This will cause the patient to be unable to cope with the above situation during the actual operation, and the eyes will rotate involuntarily, affecting the effect of the operation.

[0007] 2. The above device cannot adjust the angle of the training instrument during the inspection and testing process. It can only be tested in a lying position. It cannot be tested when the patient is sitting. If the patient needs to sit for testing in some special circumstances, the posture cannot be adjusted, and the applicability is not strong.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing preoperative simulation training device for all-femtosecond laser myopia surgery. Summary of the invention

[0035] The following is combined with Figure 1-Figure 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0036] The embodiment of the present application discloses a simulated gaze trainer for all-femtosecond laser refractive surgery, which explains that the simulated gaze trainer for all-femtosecond laser refractive surgery is mainly used in the process of medical training, and can avoid the problem of not being able to simulate the blurred feeling in the patient's eyes in terms of technical effect; further, the simulated gaze trainer for all-femtosecond laser refractive surgery can also solve the problem of not being able to adjust the angle of the trainer during the inspection and test.

[0037] Embodiment 1:

[0038] Reference Figure 1 , Figure 2 and Figure 3 As shown, a full-femtosecond laser refractive surgery simulation gaze trainer includes a symmetrically arranged telescopic rod 1, and the telescopic ends of the telescopic rod 1 are rotatably installed with a support rod 10. The support rod 10 is fixed by the telescopic rod 1, and the support rod 10 is rotatably connected to the telescopic rod 1. It is beneficial to place the support rod 10 on the bed in different states to simulate the body posture of the patient during the operation, which is more beneficial to simulate the situation during the operation and improve the efficiency of the test. The support rod 10 can also be rotated so that the patient can sit down for the test, which is more convenient and quick and can adapt to different test needs.

[0039] An electric push rod 11 is installed on the support rod 10, and a test box 12 is set at the telescopic end of the electric push rod 11. An opening for human observation is opened at the bottom of the test box 12. A bidirectional screw 2 is rotated along the length direction of the test box 12. An observation frame 20 is symmetrically threaded on the bidirectional screw 2. An adaptation frame 21 is installed on the side of the observation frame 20 away from the test box 12;

[0040] By rotating the bidirectional screw 2, the observation frames 20 can be driven to move closer to or farther from each other, thereby adapting to different pupil distances of patients and improving the accuracy of the test.

[0041] The adaptable frame 21 is preferably made of existing rubber material to better fit the facial contours of different patients, thereby preventing light leakage caused by the adaptable frame 21 not adapting to the facial contours of the patient during the test, thereby affecting the test effect.

[0042] A testing mechanism 3 is also installed inside the testing box 12 for cooperating with the observation frame 20 to perform simulated gaze training.

[0043] Reference Figure 3 and Figure 4As shown, it is a schematic diagram of the structure for performing a simulated gaze test on a patient; specifically, the test mechanism 3 includes a first screw 30 rotatably installed inside the test box 12 and arranged parallel to the bidirectional screw 2, a threaded seat 31 is threadedly connected to the first screw 30, and a test component 32 which is an overall square is arranged on the threaded seat 31. The first screw 30 drives the threaded seat 31 to drive the test component 32 to perform a test record on a single eye.

[0044] It should be noted that the test component 32 includes a display screen and a camera, wherein the display screen is used to play a pre-recorded video to simulate the scene seen by the patient's eyes during the operation, and the camera is used to record the movement of the patient's eyes to determine whether the gaze effect is qualified. The display screen and the camera are both well-known existing technologies and will not be described in detail later.

[0045] A square shading tube 33 movably matched with the observation frame 20 is sleeved on the outer side of the test assembly 32 , and a square shading plate 34 vertically arranged with the shading tube 33 is slidably provided on one side of the observation frame 20 close to the shading tube 33 .

[0046] The function of the shading tube 33 is to prevent external light from affecting the operation of the display screen and the test results of the patient during the test. During the actual operation, in order to ensure the safety and accuracy of the operation, the doctor will first operate on one eye, and then operate on the other eye after confirming that everything is normal. The function of setting the shading plate 34 can simulate the actual surgical process. When testing one eye, the shading plate 34 will be used to block the other eye to prevent the other eye from observing other external objects and affecting the test efficiency.

[0047] Reference Figure 3 , Figure 4 and Figure 5 As shown, it is a schematic diagram of the structure for driving the shading plate 34 to move; specifically, a driving member 4 for driving the shading plate 34 to move is provided on the test box 12, and the driving member 4 includes a second screw 40, a driving groove is provided on one side of the shading plate 34, the second screw 40 is installed in the driving groove, and a driving shaft 42 sliding in the driving groove is sleeved on the outer side of the second screw 40, and the end of the driving shaft 42 away from the shading plate 34 is rotatably arranged on the inner wall of the test box 12, a connecting block 43 is provided on the side wall of the shading plate 34, and a slide groove 41 is provided on the test box 12, and the connecting block 43 is slidably arranged in the slide groove 41.

[0048] The second screw 40 is driven to slide inside the driving shaft 42 by rotating the driving shaft 42, and then the second screw 40 can drive the shading plate 34 to slide inside the test box 12. The purpose of setting the connecting block 43 is to prevent the second screw 40 from rotating with the driving shaft 42 when the driving shaft 42 rotates, so that the shading plate 34 cannot slide in the test box 12, so the connecting block 43 can limit the shading plate 34 to ensure that the shading plate 34 can slide along the length direction of the slide groove 41.

[0049] Reference Figure 4 and Figure 5 As shown, it is a schematic diagram of the structure that drives the test component 32 and the shading plate 34 to cooperate with each other; specifically, a linkage member 5 is also provided in the test box 12 to enable the test component 32 and the shading plate 34 to cooperate with each other, and the linkage member 5 includes a linkage shaft 50 rotatably installed in the test box 12, a linkage gear 51 is provided on the linkage shaft 50, and a linkage rack 52 meshing with the linkage gear 51 is installed on the threaded seat 31, and the linkage shaft 50 is respectively connected to the two driving shafts 42 through belt transmission.

[0050] When the first screw 30 drives the test assembly 32 to move, the linkage rack 52 connected to the threaded seat 31 will move along with the threaded seat 31, and then drive the linkage shaft 50 to rotate with the cooperation of the linkage rack 52 and the linkage gear 51. When the linkage shaft 50 rotates, it will drive the two driving shafts 42 connected to the linkage shaft 50 through belt transmission to rotate, so that the shading plate 34 connected to the driving shaft 42 through the second screw 40 can slide in the test box 12.

[0051] It should be noted that the thread directions of the two second screws 40 are opposite, which will cause the movement directions of the two shading plates 34 to be opposite. When the test assembly 32 on the threaded seat 31 overlaps with the observation frame 20 corresponding to the eye to be tested, the shading plate 34 corresponding to the observation frame 20 will rise accordingly, and the other shading plate 34 will drop to block the other eye.

[0052] Reference Figure 3 and Figure 6 As shown, it is a schematic diagram of the structure that simulates the defocusing process of the human eye during surgery; specifically, a blur component 6 is provided on the shading tube 33, and the blur component 6 includes a rotating shaft 61 rotatably installed on the outer wall of the shading tube 33, and a plurality of fixing rings 62 are equidistantly arranged on the rotating shaft 61 through a torsion spring, and a fixing frame 63 is installed on the fixing ring 62, and each fixing frame 63 is provided with a blur lens with a different blur coefficient (not shown in the figure), and a plurality of matching grooves matching with the fixing frame 63 are opened on the shading tube 33.

[0053] The blurring lens on the fixing ring 62 can simulate different blurring degrees when the human eye views the screen. By rotating the fixing ring 62, the fixing frame 63 is driven to rotate, driving the blurring lens into the light shielding tube 33 to simulate the blurring effect.

[0054] A light shielding ring 64 is also installed on the fixing ring 62. The light shielding ring 64 and the fixing frame 63 are symmetrically distributed. The sizes of the fixing frame 63 and the light shielding ring 64 are consistent with the size of the matching groove.

[0055] Since a plurality of matching grooves are provided on the shading tube 33 for the blurring lens to enter, when the blurring lens has not entered the shading tube 33, the matching grooves are sealed by the shading ring 64 on the fixing ring 62 to prevent external light sources from entering the shading tube 33 and affecting the test results.

[0056] Reference Figure 6 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure for driving the fixed ring 62 to rotate; specifically, a third screw 70 extending to the outside of the test box 12 is installed inside the rotating shaft 61, and a moving block 71 is threadedly arranged on the third screw 70. A driving block 72 extending to the outside of the rotating shaft 61 is installed on the moving block 71. A moving groove 73 for driving sliding is opened on the rotating shaft 61, and a spiral groove 74 is opened on the fixed ring 62. The driving block 72 is slidably connected with the spiral groove 74.

[0057] The third screw 70 rotates, driving the moving block 71 to move inside the rotating shaft 61. During this process, the driving block 72 on the moving block 71 will slide along the moving groove 73 on the rotating shaft 61. When the driving block 72 moves to the fixed ring 62, it will enter the spiral groove 74 on the fixed ring 62. Since the driving block 72 will not rotate, the rising of the driving block 72 will drive the fixed ring 62 to rotate through the cooperation with the spiral groove 74, and then the blurred lens will rotate into the shading tube 33. When the blurred lens needs to be moved out of the shading tube 33, the third screw 70 is rotated again to drive the driving block 72 on the moving block 71 through the spiral groove 74 away from the fixed ring 62, and then the fixed ring 62 will return to its initial state under the action of the torsion spring.

[0058] Reference Fig. 9 and Fig.10 As shown, it is a schematic diagram of the structure for fixing the rotating support rod 10; specifically, the support rod 10 is rotatably connected to the telescopic rod 1 via a connecting shaft 80, and the connecting shaft 80 is located in a section inside the telescopic rod 1 and has multiple fixed grooves 81 equidistantly provided therein, and a telescopic groove is provided on the telescopic rod 1, in which a telescopic spring rod 82 is installed, and a limit block 83 movably connected to the fixed groove 81 is provided at the telescopic end of the telescopic spring rod 82.

[0059] When the support rod 10 rotates between the telescopic rods 1, the connecting shaft 80 will rotate on the telescopic rod 1. When the fixing groove 81 on the connecting shaft 80 aligns with the limiting block 83, the limiting block 83 will slide into the fixing groove 81 under the elastic force of the telescopic spring rod 82 to fix the rotating shaft 61, and then fix the support rod 10.

[0060] To prevent the support rod 10 from rotating under the action of gravity or other external forces, which may cause a reverse force on the telescopic spring rod 82 and make the limiting block 83 on the telescopic spring rod 82 slide out of the fixing groove 81, a clamping groove (not shown in the figure) is provided at the telescopic end of the telescopic spring rod 82. A pressing shaft 84 is slidably inserted through the telescopic end of the telescopic rod 1. One end of the pressing shaft 84 located inside the telescopic rod 1 is movably matched with the clamping groove, and the other end of the pressing shaft 84 passes through the telescopic rod 1 and is provided with a pressing block 85.

[0061] After the limiting block 83 slides into the fixing groove 81, push the pressing shaft 84 to insert the end of the pressing shaft 84 located inside the telescopic rod 1 into the clamping groove, preventing the support rod 1 from rotating under the action of gravity and generating a reverse force on the limiting block 83, which may cause the limiting block 83 to retract into the telescopic groove. Use the pressing shaft 84 to fix the telescopic end of the telescopic rod 1 to prevent the limiting block 83 from retracting; when it is necessary to rotate the support rod 1, the pressing block 85 needs to be pulled to release the limit of the telescopic rod 1 by the pressing shaft 84. Embodiment

[0062] On the basis of Embodiment 1, in order to fix the telescopic rod 1, a fixing member 9 is further proposed, which is beneficial to fix the telescopic rod 1 on the hospital bed or chair, facilitating the pre-operative test.

[0063] Refer to Fig. 9 and Fig.10 As shown, it is a schematic structural diagram for fixing the telescopic rod 1; specifically, a fixing member 9 for fixing the telescopic rod 1 is provided on the fixed end of the telescopic rod 1. The fixing member 9 includes a fourth screw 90, which is rotatably arranged on the opposite sides of the two telescopic rods 1. A limiting rod 91 is also provided on the opposite sides of the telescopic rods 1. A fixing block 92 with a U-shaped structure is jointly arranged on the fourth screw 90 and the limiting rod 91 through a fixing plate. A fixing screw 93 with one end passing through the fixing block 92 is rotatably threaded at the bottom of the fixing block 92.

[0064] By rotating the fourth screw 90, it is possible to drive the fixing block 92 to move through the fixing plate to adapt to beds or chairs of different sizes. Clamp the fixing block 92 on the bedside guardrail or the armrest of the chair, and then rotate the fixing screw 93 to make the end of the fixing screw 93 located inside the fixing block 92 abut against the guardrail or the armrest, thereby fixing the telescopic rod 1.

[0065] During operation: the first step is to fix the support rod 10 with the telescopic rod 1, place the support rod 10 on the bed or chair, rotate the support rod 10, align the test box 12 on the support rod 10 with the face, and drive the adaptation frame 21 on the test box 12 to align with the patient's eyes.

[0066] Step 2: Rotate the bidirectional screw 2 to drive the observation frames 20 to move closer to or farther from each other to adapt to different pupil distances of patients.

[0067] Step 3: Rotate the first screw rod 30 to drive the threaded seat 31 to drive the test assembly 32 to test and record a single eye.

[0068] Step 4: Rotate the third screw 70 to drive the moving block 71 to move inside the rotating shaft 61. The driving block 72 on the moving block 71 will slide along the moving groove 73 on the rotating shaft 61, so that the driving block 72 enters the spiral groove 74 on the fixed ring 62 to simulate the blur effect.

[0069] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
