Description

Technical Field

[0001] The present invention relates to the technical field of medical prisms, in particular to a multifunctional auxiliary device for medical prisms. Background Art

[0002] A medical prism is usually composed of a triangular transparent body formed by the intersection of two planes. The line where the two planes intersect is the edge, called the vertex. The plane opposite to the vertex is the base. The line perpendicular to the base and the vertex is the base-vertex line. The section perpendicular to the base-vertex line and the two planes is the principal section. When light passes through a prism, it will be refracted and deflected toward the base of the prism. When we look at the light point through the prism, the position of the light point (object) shifts toward the tip of the prism.

[0003] When most existing medical prisms are used, a doctor generally holds the prism in front of the patient's eyes, shields the prism with his hands, and examines the patient's eyes based on the doctor's experience.

[0004] Doctors use medical prisms to examine patients' eyes. However, when using most existing medical prisms, doctors generally hold the prism in their hands and place it on the patient's eyes to examine the patient's eyes. However, the patient's head cannot be fixed. As a result, when the doctor places the prism, the position of the prism is offset due to the movement of the doctor's hand and the patient's head, which may cause the doctor's examination results to deviate, making the medical prism more inconvenient to use.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The present invention provides a multifunctional auxiliary device for medical prism, such as Figures 1-6 As shown, the multifunctional auxiliary device for medical prisms includes a mounting base 1, handles 5 are fixedly connected to both sides of the mounting base 1, and support legs are fixedly connected to the four corners of the lower surface of the mounting base 1. The provision of the support legs makes the multifunctional auxiliary device for medical prisms more stable when in use, and the provision of the handles 5 makes the multifunctional auxiliary device for medical prisms more convenient to move, thereby making the multifunctional auxiliary device for medical prisms more convenient to take;

[0033] A head support mechanism 2 is mounted on the upper surface of the mounting base 1. The head support mechanism 2 includes a plurality of hollow cylinders 201 fixedly connected to the upper surface of the mounting base 1. An electric push rod 202 is fixedly connected to the interior of the hollow cylinder 201. The output end of the electric push rod 202 is fixedly connected to a moving rod 203. The arrangement of the electric push rod 202 makes it easier to move the support plate 204 and the soft cushion 205.

[0034] The surfaces of several moving rods 203 are fixedly connected to a support plate 204. The upper surface of the support plate 204 is fixedly connected to a soft pad 205 by bolts. One side of the upper surface of the support plate 204 is fixedly connected to a soft baffle 206. The interior of the moving rod 203 is fixedly connected to a tightening spring 207. One end of the tightening spring 207 is fixedly connected to an adjustment rod 208 that is slidably connected to the moving rod 203. One end of several adjustment rods 208 is fixedly connected to a head top plate 209. The head top plate 209 is fixedly connected to the head top plate 209. 9 is provided with a groove on its lower surface, and the head top plate 209 corresponds to the support plate 204. When the head top plate 209 is lifted, the patient places his chin on the soft cushion 205 and is located behind the soft baffle 206. The elastic force of the spring 207 causes the head top plate 209 to move downward following the adjustment rod 208, so that the groove on the head top plate 209 fits with the top of the patient's head. The soft cushion 205 and the head top plate 209 exert a certain force on the patient's head to limit the patient's head.

[0035] A spotlight adjustment mechanism 3 is installed in the middle of the upper surface of the mounting base 1, and a prism adjustment mechanism 4 is installed on the surface of the spotlight adjustment mechanism 3. The prism adjustment mechanism 4 includes a mounting plate 401 mounted on the surface of the spotlight adjustment mechanism 3, a fixing plate 402 is fixedly connected to the upper surface of the mounting plate 401, a driving motor 403 is fixedly connected to the interior of the fixing plate 402, and the output end of the driving motor 403 is fixedly connected to a threaded rod 404 that is rotatably connected to the interior of the fixing plate 402 through a bearing seat, and a sliding block 405 that is slidably connected to the interior of the fixing plate 402 is threadedly connected to the surface of the threaded rod 404. The adjustment mechanism 4 also includes a driving toothed plate 406 slidably connected to the interior of the sliding block 405. A counterweight is fixedly connected to one side of the upper surface of the driving toothed plate 406 in a path array. A support box 7 is sleeved on the surface of the driving toothed plate 406. A support rod fixedly connected to the surface of the support box 7 is fixedly connected to the mounting plate 401. When the driving motor 403 is started, its output end drives the threaded rod 404 to rotate inside the mounting plate 401, thereby causing the sliding block 405 to slide inside the mounting plate 401, driving the driving toothed plate 406 and the mounting bracket 407 to move synchronously, thereby adjusting the height of the prism body 409.

[0036] One side of the driving tooth plate 406 is fixedly connected to a mounting bracket 407, and both ends of the mounting bracket 407 are fixedly connected to elastic rods 408. The opposite sides of the two elastic rods 408 are commonly attached to the prism body 409. The surface of the sliding block 405 is mounted with a driving mechanism 6, which includes a driving motor 601 fixedly connected to the surface of the sliding block 405. The driving motor 601 has an output end fixedly connected to a driving gear 602 corresponding to the driving tooth plate 406. The surface of the sliding block 405 is provided with a communicating groove corresponding to the driving gear 602. When the driving motor 601 is started, its output end drives the driving gear 602 to rotate, thereby causing the driving gear 602 to drive the driving tooth plate 406 to engage and move, so that the mounting bracket 407 and the prism body 409 move accordingly, thereby adjusting the left and right positions of the prism body 409.

[0037] The prism adjustment mechanism 4 further includes a guide rod 410 fixedly connected to the surface of the mounting frame 407. A shielding plate 411 corresponding to the prism body 409 is magnetically attracted to the surface of the guide rod 410. The shielding plate 411 is slidably connected to the surface of the guide rod 410. After the spotlight body 308 irradiates the patient's eyes, the shielding plate 411 is moved so that the shielding plate 411 blocks different positions of the prism body 409, thereby making it more convenient for the doctor to examine the patient's eyes.

[0038] The prism body 409 corresponds to the head support mechanism 2, and the spotlight adjustment mechanism 3 includes a servo motor 301 fixedly connected to the middle part of the upper surface of the mounting base plate 1. The output end of the servo motor 301 is fixedly connected to a screw 302. The surface of the screw 302 is sleeved with a fixing box 303 fixedly connected to the mounting base plate 1. The mounting plate 401 is fixedly connected to the fixing box 303. Both sides of the interior of the fixing box 303 are sleeved with limit rods 304 corresponding to the screw 302. Through the setting of the servo motor 301, the screw 302 can drive the support frame 306 to move through the limit of the limit rod 304 and the movable rod 305, so that the support frame 306 drives the spotlight body 308 to move, adjust the position of the spotlight body 308, so that the spotlight body 308 can be suitable for inspections at different distances;

[0039] The spotlight adjustment mechanism 3 also includes three movable rods 305 slidably connected to the inside of the fixed box 303, one of the movable rods 305 is threadedly connected to the screw 302, and the other two movable rods 305 are respectively sleeved on the surface of the limit rod 304. The surfaces of the three movable rods 305 are commonly fixedly connected to a support frame 306, and a metal hose 307 is fixedly connected to one side of the support frame 306. The spotlight main body 308 is movable. Through the setting of the metal hose 307, the spotlight main body 308 can be moved to any position to illuminate the patient's eyes and the prism main body 409, so that the spotlight main body 308 is more convenient for auxiliary examination of the patient's eyes. The spotlight main body 308 is plugged into one end of the metal hose 307.

[0040] Specifically, when the multifunctional auxiliary device for medical prism is used: the multifunctional auxiliary device for medical prism is placed in the desired position by using the handle 5, the head top plate 209 is lifted, and the patient is asked to place his chin on the soft cushion 205 and behind the soft baffle 206. The elastic force of the spring 207 is used to make the head top plate 209 move downward along with the adjustment rod 208, so that the groove on the head top plate 209 fits with the top of the patient's head. A certain force is applied to the patient's head through the soft cushion 205 and the head top plate 209 to limit the patient's head, thereby making the patient's head more stable during examination.

[0041] According to the position of the patient's eye, the drive motor 403 is started, and its output end drives the threaded rod 404 to rotate inside the mounting plate 401, so that the sliding block 405 slides inside the mounting plate 401, driving the driving gear plate 406 and the mounting frame 407 to move synchronously, thereby adjusting the height of the prism body 409. Then, the drive motor 601 is started, and its output end drives the driving gear 602 to rotate, so that the driving gear 602 drives the driving gear plate 406 to engage and move, so that the mounting frame 407 and the prism body 409 follow the movement, and the left and right position of the prism body 409 is adjusted, thereby making the position adjustment of the prism body 409 more convenient, so that the prism body 409 is more suitable for the patient's eye.

[0042] Then, the spotlight body 308 is moved. Through the setting of the metal hose 307, the spotlight body 308 can be moved to any position to illuminate the patient's eyes and the prism body 409, thereby making it more convenient for the spotlight body 308 to perform auxiliary examinations on the patient's eyes. In addition, through the setting of the servo motor 301, the screw 302 can drive the support frame 306 to move through the limit of the limit rod 304 and the movable rod 305, so that the support frame 306 drives the spotlight body 308 to move, and the position of the spotlight body 308 can be adjusted, so that the spotlight body 308 can be used for examinations at different distances.

[0043] After the spotlight body 308 irradiates the patient's eyes, the shielding plate 411 is moved so that the shielding plate 411 blocks different positions of the prism body 409, thereby making it more convenient for the doctor to examine the patient's eyes. In addition, the magnetic attraction between the shielding plate 411 and the guide rod 410 not only makes it more convenient to move the shielding plate 411, but also makes it more stable after moving.

[0044] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
