Description

Technical Field

[0001] This utility model relates to the field of medical teaching aids technology, and in particular to a teaching tool for eye surgery. Background Technology

[0002] With the application of laser technology in the treatment of retinal diseases, retinal laser treatment equipment has become widely available. However, this has also led to a shortage of qualified doctors and practitioners proficient in using these devices. Therefore, the use of eyeball models as teaching aids is necessary in the training of relevant personnel.

[0003] Traditional teaching tools for ophthalmic surgery have some drawbacks. In the process of using ophthalmic surgical teaching aids, most eye models are fixed and their height and position cannot be adjusted. When simulating different surgical approaches, different eye exposure positions, and different patient orbital depths, the height of the eye model cannot be moved up and down to adjust. It is difficult to match the actual exposure height and operating angle of the eye in real surgery. Trainees can only practice at a fixed height and cannot reproduce the changes in operation caused by differences in patient orbital depth and eyelid tightness in clinical practice. This results in a single training scenario and a large difference from real surgery. Utility Model Content

[0004] The main purpose of this invention is to provide a teaching tool for ocular surgery that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A teaching tool for ocular surgery includes a support column and an eye model. The front end of the support column is equipped with an adjustment auxiliary mechanism. The adjustment auxiliary mechanism includes a sliding rail fixedly connected to the front end of the support column, a carriage slidably connected to the outer side of the sliding rail, a limit hole at one end of the sliding rail, a mounting block fixedly connected to the front end of the carriage, a control groove at one end of the carriage, an adjustment plate slidably connected to the inner side of the control groove, a limit block fixedly connected to one end of the adjustment plate, an adjustment frame fixedly connected to the side of the carriage closest to the control groove, a threaded rod threadedly connected to the inner side of the adjustment frame, a connecting block movably connected to the inside of the adjustment plate, and an indicator needle fixedly connected to the inner wall of the control groove.

[0007] Preferably, a knob is fixedly connected to one end of the threaded rod, a mating plate is fixedly connected to the upper end of the sliding rail, a screw is threaded inside the mating plate, and the control groove corresponds to the limiting hole.

[0008] Preferably, the outer side of the limiting block is movably connected to the inner side of the limiting hole, and there are multiple sets of limiting holes. One end of the connecting block is fixedly connected to the other end of the threaded rod.

[0009] Preferably, the screw extends into the interior of the support column, the screw is threadedly connected to the support column, and the indicator needle corresponds to one of the sets of limiting holes.

[0010] Preferably, a base plate is fixedly connected to the lower end of the support column, a connecting frame is fixedly connected to the outer side of the mounting block, a mounting frame is fixedly connected to the front end of the connecting frame, and the eyeball model is movably mounted in the inner side of the mounting frame via a rotating shaft.

[0011] Preferably, the axis of the connecting frame, the mounting frame, and the eyeball model are located on the same straight line, and the eyeball model is located above the base plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By rotating the threaded rod, it moves within the adjustment frame, which in turn moves the control plate via the connecting block. This causes the limiting block to disengage from the limiting hole, pulling the slide along the sliding rail. This allows for easy adjustment of the eyeball model's height, enabling it to fit different positions and match the actual exposure height and operating angle of the eyeball during real surgery. It also replicates the operational changes caused by differences in the depth of the patient's orbit and the tightness of the eyelids during clinical practice. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a teaching tool for ocular surgery includes a support column 1 and an eye model 5. An adjustment auxiliary mechanism 6 is provided at the front end of the support column 1. The adjustment auxiliary mechanism 6 includes a sliding rail 61 fixedly connected to the front end of the support column 1. A carriage 63 is slidably connected to the outer side of the sliding rail 61. A limit hole 62 is provided at one end of the sliding rail 61. An mounting block 64 is fixedly connected to the front end of the carriage 63. A control groove 65 is provided at one end of the carriage 63. An adjustment plate 66 is slidably connected to the inner side of the control groove 65. A limit block 67 is fixedly connected to one end of the adjustment plate 66. An adjustment frame 68 is fixedly connected to the side of the carriage 63 closest to the control groove 65. A threaded rod 69 is threadedly connected to the inner side of the adjustment frame 68. A connecting block 610 is movably connected inside the adjustment plate 66. An indicator needle 614 is fixedly connected to the inner wall of the control groove 65.

[0021] In this embodiment, a knob 611 is fixedly connected to one end of the threaded rod 69, a mating plate 612 is fixedly connected to the upper end of the sliding rail 61, a screw 613 is threadedly connected inside the mating plate 612, the control groove 65 corresponds to the limiting hole 62, the outer side of the limiting block 67 is movably connected to the inner side of the limiting hole 62, there are multiple sets of limiting holes 62, one end of the connecting block 610 is fixedly connected to the other end of the threaded rod 69, the screw 613 extends into the interior of the support column 1, the screw 613 is threadedly connected to the support column 1, and the indicator needle 614 corresponds to one set of limiting holes 62.

[0022] Specifically, rotating knob 611 causes the threaded rod 69 to rotate, which in turn moves the threaded rod 69 within the adjusting bracket 68. The threaded rod 69, via connecting block 610, moves the adjusting plate 66, causing the adjusting plate 66 to disengage the limiting block 67 from the inner side of the limiting hole 62. Then, pulling the slide 63 causes it to slide along the sliding rail 61, which in turn moves the eyeball model 5 via mounting block 64, causing the indicator needle 614 to point to the new limiting hole 62. This allows the eyeball model 5 to be moved to the designated height. Then, rotating knob 611 in the opposite direction causes the threaded rod 69, via connecting block 610, to push the adjusting plate 66 in the opposite direction, and inserts the limiting block 67. Once the new limiting hole 62 is in place, the slide 63 is positioned outside the sliding rail 61, thereby limiting the eyeball model 5 to a specified height. This allows the eyeball model 5 to be adapted to different positions. By rotating the threaded rod 69, the threaded rod 69 moves within the adjusting frame 68, which in turn drives the adjusting plate 66 to move via the connecting block 610. This causes the limiting block 67 to disengage from the limiting hole 62, thereby pulling the slide 63 to slide along the sliding rail 61. This allows for easy adjustment of the height of the eyeball model 5, enabling it to be adapted to different positions and matching the actual exposure height and operating angle of the eyeball during real surgery. This also replicates the operational changes caused by differences in the depth of the patient's orbit and the tightness of the eyelids during clinical practice.

[0023] In this embodiment, the lower end of the support column 1 is fixedly connected to the base plate 2, the outer side of the mounting block 64 is fixedly connected to the connecting frame 3, the front end of the connecting frame 3 is fixedly connected to the mounting frame 4, and the eyeball model 5 is movably mounted in the inner side of the mounting frame 4 through a rotating shaft. The axis lines of the connecting frame 3, the mounting frame 4, and the eyeball model 5 are located on the same straight line, and the eyeball model 5 is located above the base plate 2.

[0024] Specifically, first place the base plate 2 on the desk, then stand the eyeball model 5 upright on the desk, and then pull the eyeball model 5 to make it rotate slightly inside the mounting bracket 4, thereby fine-tuning the eyeball model 5, and then you can use the eyeball model 5 for classroom teaching.

[0025] Working principle:

[0026] In use, first place the base plate 2 on the desk, then stand the eyeball model 5 upright on the table. Next, turn the knob 611 to rotate the threaded rod 69, causing it to move within the adjusting bracket 68. The threaded rod 69, via the connecting block 610, moves the control plate 66, causing the control plate 66 to disengage the limiting block 67 from the inner side of the limiting hole 62. Then, pull the slide 63, causing it to slide along the sliding rail 61. This allows the slide 63 to move the eyeball model 5 via the mounting block 64, pointing the indicator needle 614 to the new limiting hole 62. The eyeball model 5 can then be moved to the designated height. Then, turn the knob 611 in the opposite direction, causing the threaded rod 69, via the connecting block 610, to push the control plate 66 in the opposite direction, inserting the limiting block 67 into the new limiting hole 62, thus limiting the slide 63. The eyeball model 5 is fixed at the outer side of the sliding rail 61, thus limiting it to a specified height. This allows the eyeball model 5 to be adapted to different positions. Then, pulling the eyeball model 5 causes it to rotate slightly inside the mounting frame 4, allowing for fine-tuning. The eyeball model 5 can then be used for classroom teaching. By rotating the threaded rod 69, it moves within the adjusting frame 68, which in turn moves the adjusting plate 66 via the connecting block 610. This causes the limiting block 67 to disengage from the limiting hole 62, thereby pulling the slide 63 to slide along the sliding rail 61. This facilitates the adjustment of the height of the eyeball model 5, allowing it to be adapted to different positions and matching the actual exposure height and operating angle of the eyeball in real surgery. This also replicates the operational changes caused by differences in the depth of the patient's orbit and the tightness of the eyelids in clinical practice.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
