Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to a portable ophthalmic strabismus detection device. Background Art

[0002] Strabismus refers to the clinical phenomenon of deviation of the visual axis of either eye. Strabismus is one of the most common eye diseases in ophthalmology. Patients with strabismus cannot look at the same object with both eyes at the same time. Patients with strabismus usually also have serious problems such as asymmetric eye position, dyslexia, poor stereoscopic sense, and inability to accurately judge the position and distance of objects, which seriously affect the patient's appearance and the normal establishment of binocular vision function. Therefore, timely and correct treatment is very necessary. In addition to the correct fitting of glasses, strabismus correction surgery, as an effective means of treating most strabismus, has accumulated considerable clinical experience. In order to achieve satisfactory clinical results, it is first necessary to accurately measure the strabismus before surgery. The measurement of strabismus is the most important step before strabismus surgery.

[0003] At present, the main methods for measuring strabismus include corneal reflection method, prism examination method, Maddox rod plus prism examination method, etc. At present, these methods basically require doctors to hold a prism in their hands, and sometimes even need the help of patients to hold the lens to complete. They have the disadvantages of low accuracy, the accuracy of the test results is greatly affected by the operation level, and the doctor holding too many test devices during the test affects the test. Therefore, designing a strabismus detection device to replace the doctor's hand-held test lens operation can free the doctor's hands while reducing the influence of subjective factors on the accuracy of strabismus measurement and reducing the consumption of invalid time, which has important clinical treatment significance. Summary of the invention

[0004] In view of the defects existing in the existing strabismus detection process, the present invention proposes a portable ophthalmic strabismus detection device, which can effectively reduce the inconvenience of doctors' operation and improve the detection accuracy of strabismus.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] A portable ophthalmic strabismus detection device comprises a base module for supporting the whole device, an optical module for realizing strabismus angle detection, a rotation module for adjusting different strabismus angles and strabismus types, and a positioning module;

[0007] The positioning module comprises a positioning spring, a positioning push head, an optical module positioning hole, a front disc positioning hole, a rear disc positioning hole, an optical module positioning spring mounting hole, a front disc positioning spring mounting hole and a rear disc positioning spring mounting hole.

[0008] The optical module includes an optical lens and a plastic frame, which are fixedly connected as a whole by bonding. The rotational movement of the optical lens is achieved by moving the plastic frame, and the orientation of the angle of the optical lens itself is fixed by the positioning module.

[0009] The rotating module includes a front disc knob, a rear disc knob, a front disc, a rear disc, an optical module and a lens limit block. The rotational movement of the front disc is controlled by the front disc knob through the formed connection between the front disc and the front disc. The front disc is circumferentially positioned by a positioning spring, a positioning push head, a front disc positioning hole and a front disc positioning spring mounting hole. The rotational movement of the rear disc is controlled by the rear disc knob through the formed connection between the rear disc knob and the rear disc. The rear disc is circumferentially positioned by a positioning spring, a positioning push head, a rear disc positioning hole and a rear disc positioning spring mounting hole. The rotational movement of the optical module is controlled by toggling the outer edge of the plastic frame. The optical module is circumferentially positioned by the positioning spring, the positioning push head, the optical module positioning hole and the optical module positioning spring mounting hole.

[0010] The base module comprises a supporting frame, a front disc limiting block and a rear disc limiting block, which fix the movement range of the front disc and the rear disc.

[0011] Preferably, the overall shape of the optical lens is approximately cylindrical, with a horizontal lower plane and a certain angle between the upper and lower planes. Different optical lenses have different angles between the upper and lower planes, and different angles correspond to different degrees of strabismus.

[0012] Preferably, the optical lens is fixedly connected to the plastic frame, and the optical lens is driven to rotate by applying a rotational motion to the plastic frame.

[0013] Preferably, the direction of the angle between the upper and lower planes of the optical lens determines the type of strabismus to be detected, and the direction of the angle between the upper and lower planes of the optical lens is determined by fixing the plastic frame by the positioning module, thereby selecting the type of strabismus to be detected.

[0014] Preferably, the optical modules are installed in the front and rear disks through lens limit blocks, the movements of the optical modules are independent of each other, and the selection of the optical lenses in the optical modules is controlled by the rotational positioning of the front and rear disks.

[0015] Preferably, the lower plane of the optical lens in the front disk faces the rear disk, and the lower plane of the optical lens in the rear disk faces the front disk. The lower planes of the two optical lenses in the front disk and the rear disk are respectively parallel to the middle plane between the front disk and the rear disk, and a tiny parallel gap is formed between the two optical lenses, so that all degrees of strabismus can be detected by the combination of the optical lenses in the front and rear disks.

[0016] Preferably, the optical lenses in the front disk total 10 pieces, corresponding to the strabismus degree of 0-4.5 degrees, and the optical lenses in the rear disk total 10 pieces, corresponding to the strabismus degree of 0-45 degrees. The combination of the optical lenses of the front and rear disks achieves a strabismus degree detection range of 0-49.5 degrees and a detection accuracy of 0.5 degrees.

[0017] Preferably, the rotational movement of the front disc is driven by the front disc knob via a formed connection between the front disc knob and the front disc.

[0018] Preferably, the rotational movement of the rear disc is driven by the rear disc knob via a formed connection between the rear disc knob and the rear disc.

[0019] Preferably, the formed connection between the rear disc knob and the rear disc passes through the front disc, and the rear disc knob is located in front of the front disc knob, and the front disc and the rear disc are controlled respectively by the front disc knob and the rear disc knob in front of the device.

[0020] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or understood by implementing the embodiments of the present application. The purpose and other advantages of the present application can be realized and obtained by the structures specifically pointed out in the written description and the drawings.

[0021] The beneficial effects of the present invention are:

[0022] 1. This portable ophthalmic strabismus detection device is composed of multiple independent modules, which are easy to assemble and reliable to cooperate. When individual modules need to be replaced, other modules will not be affected;

[0023] 2. The optical lens used in this portable ophthalmic strabismus detection device is similar to a cylinder, and the upper and lower planes of the optical lens present a certain angle. Different optical lenses have different upper and lower plane angles, and different angles correspond to different strabismus. The optical lens has the same detection effect as the original prism while reducing the volume of the optical lens;

[0024] 3. In this portable ophthalmic strabismus detection device, the rotation of the optical lens is driven by a plastic frame fixedly connected to the optical lens. During the strabismus detection process, the optical lens will not be accidentally touched, thus preventing the optical lens from being contaminated.

[0025] 4. This portable ophthalmic strabismus detection device can detect four types of strabismus, namely, upward strabismus, downward strabismus, left strabismus, and right strabismus, by changing the direction of the angle between the upper and lower planes of the optical lens;

[0026] 5. In this portable ophthalmic strabismus detection device, the optical lenses installed in the front and rear discs are independent of each other, and the movements of the optical lenses do not affect each other. Optical lenses representing different strabismus are selected through the rotation of the front and rear discs;

[0027] 6. In this portable ophthalmic strabismus detection device, the optical lens installed in the front plate and the optical lens installed in the rear plate form a tiny parallel gap at the middle surface between the front plate and the rear plate. The existence of the parallel gap not only eliminates interference between the rotational motions of the front plate and the rear plate, but also makes the strabismus detected by the device equal to the strabismus represented by the optical lens of the front plate plus the strabismus represented by the optical lens of the rear plate;

[0028] 7. This portable ophthalmic strabismus detection device realizes a strabismus detection range of 0-49.5 degrees and a detection accuracy of 0.5 degrees by combining 10 optical lenses representing 0-4.5 degrees strabismus in the front plate and 10 lenses representing 0-45 degrees strabismus in the rear plate;

[0029] 8. In this portable ophthalmic strabismus detection device, the rotational movement of the front disk is independently controlled by the front disk knob;

[0030] 9. In this portable ophthalmic strabismus detection device, the rotational movement of the rear disc is independently controlled by the rear disc knob;

[0031] 10. The front and rear disc knobs of this portable ophthalmic strabismus detection device are both located at the front of the device, making it easy to operate the front and rear discs. BRIEF DESCRIPTION OF THE DRAWINGS
