Technical Field
[0001] The present application relates to the technical field of medical devices, and in particular to a multifunctional gonioscopic lens. Background Art
[0002] A gonioscope is a contact lens that observes the structure of the anterior chamber angle through the refraction and reflection of light. Due to the different refractive indices of the cornea and air, light produces total internal reflection at the cornea, making it impossible to directly observe the structure of the anterior chamber angle. By eliminating this total internal reflection, the gonioscope allows doctors to clearly see the internal structure of the anterior chamber angle. Goniometery is an essential step in glaucoma examination. When diagnosing the disease, it is necessary to detect the closure and adhesion of the angle.
[0003] When using a gonioscope to examine the patient's chamber angle, existing medical staff need to hold a handheld device and gently place the lens of the gonioscope on the patient's eyeball, usually above or below the cornea, in order to observe the chamber angle structure at different parts. Since the existing gonioscope does not have a scale, medical staff can only judge the patient's chamber angle narrowness and other information based on experience, which is very likely to cause misjudgment. In addition, the existing gonioscope has a single function. Summary of the invention

[0018] Specifically, the detachable lens 11 is threadedly connected to the lens barrel 14, and the lens 15 is designed to be detachable from the detachable lens 11. After the lens 15 is inserted into the lens barrel 14, it will not be separated under the action of a strong damping force.
[0019] More specifically, an LED flexible lamp is provided at one end of the outer side surface of the lens barrel 14 close to the lens 15 , and an input end of the LED flexible lamp is electrically connected to an output end of an external power source.
[0020] The mobile phone fixing clamp 2 includes a support plate 24, and the front and rear ends of the outer side surface of the support plate 24 are slidably connected with L-shaped clamping plates 26, and the L-shaped clamping plates 26 are connected to the support plate 24 through a tension spring. The support plate 24 is connected to the mounting plate 21 through a connecting plate 23 arranged in the middle of the outer side surface thereof. The outer side surface of the mounting plate 21 is provided with a strip groove 22, and the annular groove 13 is correspondingly arranged to be clamped with the strip groove 22.
[0021] Specifically, the L-shaped clamping plate 26 is slidably connected to the positioning hole set on the outer side of the support plate 24, and the end of the L-shaped clamping plate 26 is connected to the tension spring set inside the positioning hole. Under the action of the tension spring, the L-shaped clamping plate 26 can be pressed tightly against the side of the mobile phone.
[0022] More specifically, after installing the lens system 1 on the mounting plate 21, the support plate 24 is slid along the mobile phone frame to adjust the position of the lens system 1 on the back of the mobile phone until the lens system 1 is adjusted to the plane where the mobile phone camera is located, stop sliding the support plate 24, and then slide and adjust the lens system 1 along the strip groove 22 until the lens system 1 is aligned with the mobile phone camera.
[0023] The mobile phone fixing clamp 2 can be adapted to mobile phones of different models. Since the sizes of mobile phones of different models are inconsistent, an L-shaped clamp 26 with a certain elasticity is provided so that the L-shaped clamp 26 can be clamped on the frames of mobile phones of different sizes. At the same time, since the positions of cameras of mobile phones of different models are inconsistent, when the mobile phone fixing clamp 2 fixes the position of the lens barrel 14, the lens barrel 14 can be driven to move up and down by sliding the position of the mobile phone fixing clamp 2 up and down. The position of the lens barrel 14 can be moved back and forth along the strip groove 22 to realize the forward and backward movement of the lens group system 1. At the same time, since the protruding heights of cameras of different mobile phones are inconsistent, the height adjustment stud 25 can be rotated so that the lower end of the adjustment stud 25 is pressed tightly against the back of the mobile phone shell, so that the height adjustment of the lens group system 1 relative to the back cover of the mobile phone can be realized.
[0024] The adjustable bracket 3 includes a circular base 35, a height-adjustable tripod 36 is installed on the lower surface of the circular base 35, a support rod 34 is provided in the middle of the upper surface of the circular base 35, and the support rod 34 is connected to a support plate 38 through a universal ball support 37 arranged on its upper end surface. The upper surface of the support plate 38 is provided with a groove, and the groove is arranged to correspond to the lens barrel 14 for clamping.
[0025] Specifically, the tripod 36 is composed of three evenly distributed telescopic rods in an annular shape. The outer side of the telescopic rod is provided with a stud for fixing its length. The telescopic end of the telescopic rod is installed with a protective pad. The position of the support plate 38 can be rotated and pitched by the universal ball support 37.
[0026] Furthermore, a positioning stud 25 is threadedly connected to the middle portion of the upper surface of the support plate 24 .
[0027] Specifically, when the detachable lens 11 is pressed tightly against the camera on the back of the mobile phone, the adjusting stud 25 is rotated so that the end of the adjusting stud 25 is against the back of the mobile phone housing. At this time, the adjusting stud 25 can lift the support plate 24 to achieve the positioning of the detachable lens 11.
[0028] More specifically, the universal ball support 37 includes an inverted cone 371, the upper end surface of the cone 371 is connected to the support plate 38, the inner side surface of the cone 371 is provided with a spherical groove, the spherical groove is sleeved with a spherical body 374, the spherical body 374 is connected to the end of the support rod 34, and the lower end of the outer side surface of the cone 371 is provided with at least one strip groove 373, the part of the spherical body 374 located in the spherical groove is larger than one half of the volume of the spherical body 374, and the lower end of the outer side surface of the cone 371 is threadedly connected with an internal threaded sleeve 372, the inner side surface of the internal threaded sleeve 372 is a curved surface that fits the outer side surface of the cone 371, and rotating the internal threaded sleeve 372 can press the cone 371 tightly against the outer side surface of the spherical body 374, thereby preventing the cone 371 and the spherical body 374 from rotating relative to each other.
[0029] After the lens barrel 14 is fixed on the adjustable bracket 3, the lifting and lowering adjustment of the lens barrel 14 can be achieved by adjusting the extension and retraction of the tripod 36. After loosening the internal threaded sleeve 372, the lens barrel 14 can be held to rotate and adjust the pitch. After the lens barrel 14 is adjusted to the right position, the internal threaded sleeve 372 is locked. Since the internal threaded sleeve 372 is pressed tightly against the outer side surface of the cone 371, and the cone 371 is pressed tightly against the outer side surface of the spherical body 374, the position of the support plate 38 is fixed under the action of the friction force between the cone 371 and the spherical body 374, and the position of the two lens barrels 14 is fixed at this time.
[0030] Furthermore, the lens 15 is plugged into the end of the lens barrel 14 .
[0031] Specifically, the plug-in arrangement facilitates quick disassembly and replacement of the lens 15 .
[0032] Furthermore, the support plate 38 is slidably connected to the upper pressure plate 32 via a column 33 arranged on its upper surface, a slot is provided on the lower surface of the upper pressure plate 32, a lifting ear 31 is provided on the upper surface of the upper pressure plate 32, and a tension spring 2 is provided between the lower surface of the upper pressure plate 32 and the upper surface of the support plate 38.

[0034] Furthermore, a slide groove 27 is provided on the lower surface of the mounting plate 21 , and the slide groove 27 is slidably connected to the detachable lens 11 .
[0035] Specifically, the arrangement of the slide groove 27 facilitates the assembly and disassembly of the detachable lens 11 .
[0036] When in use: first spray local anesthetic into the corner of the patient's eye, and operate by hand. The user holds the lens barrel 14 and puts the lens 15 close to the corner of the patient's eye. Then, the user can observe the patient's eye corner through the detachable lens 11, and obtain relevant information such as the narrowness of the patient's eye corner by reading the scale on the dust-proof glass 11.
[0037] To operate the bracket, hold the lifting ear 31 to pull open the upper pressure plate 32, then place the lens barrel 14 in the groove on the upper surface of the support plate 38, release the upper pressure plate 32, and the upper pressure plate 32 is pressed tightly against the outer side of the lens barrel 14 under the action of the spring. Then, the height of the lens barrel 14 can be adjusted through the tripod 36, and the lens barrel 14 can be rotated and pitched through the universal ball support 37, so that the lens 15 can be adjusted to a suitable operating angle.
[0038] When taking pictures with a mobile phone, first unscrew the detachable lens 11, pass the end of the lens barrel 14 through the strip groove 22, and then install the detachable lens 11 to the end of the lens barrel 14. At this time, the annular groove 13 is just inserted into the strip groove 22, and the support plate 24 is fixed to the back cover of the mobile phone through the L-shaped clamping plate 26 to ensure that the detachable lens 11 is located at the main camera of the mobile phone. Then, the lens barrel 14 is adjusted to rise and fall by rotating the adjusting stud 25, so that the detachable lens 11 can be pressed tightly against the main camera of the mobile phone, and the patient's eye corner condition can be taken through the mobile phone camera.
[0039] When it is necessary to take a picture of the corner of the patient's eye, the ring light on the outer side of the lens barrel 14 can be turned on to provide fill light.
