Description

Technical Field

[0001] The utility model belongs to the technical field of chamber angle inspection, and in particular relates to a chamber angle mirror with a lens for shooting. Background Art

[0002] The anterior chamber of the eye is the space between the iris and the cornea. The structure of the anterior chamber angle cannot be observed due to total internal reflection, which is an optical phenomenon in which the angle of light from the back of the cornea to the cornea-air interface is greater than the critical angle of the interface and is then reflected back. Therefore, a gonioscope is needed to observe the structure of the anterior chamber angle through the refraction and reflection of light.

[0003] When conducting a preliminary examination of anterior chamber lesions of the eye, the doctor needs to hold the handle of the gonioscope with one hand, align the center position of the bottom of the gonioscope with the center position of the cornea, cover his own eyes with the eyepiece, align the magnifying lens objective lens with the face mirror of the gonioscope, and use the fill light of the fill light LED and the reflection of the side prism of the gonioscope to examine the anterior chamber of the patient's eye.

[0004] However, in the actual preliminary examination of the anterior chamber angle, a full-circle examination of the anterior chamber angle is required. This process not only tests the doctor's skills in using the magnifying lens, but also requires certain skills in use due to the limited space for the fill-in LED lamp and the limited operation of the full-circle fill-in light. Therefore, for some doctors who are not particularly experienced in preliminary examination of the anterior chamber angle, it is not convenient to use this type of anterior chamber angle mirror to perform a full-circle examination of the anterior chamber angle.

[0005] For this reason, it is necessary to provide a gonioscope with a lens for shooting without wearing a magnifying lens and with supplementary light, so as to meet the needs of doctors with different preliminary examination experiences of the angle of the chamber. Utility Model Content

Under such a setting, it is conducive to the magnifying camera 14 to capture the anterior chamber angle image through the goniometer 2 from the side;

[0025] The external cover 1 is provided with a rotating mechanism on the outside, and a support disc frame 8 is installed on the rotating mechanism. The rotating mechanism is used to support the disc frame 8 to rotate around the external cover 1. A sliding mechanism is provided on the support disc frame 8. A mobile vertical pipe 12 is inserted in the sliding mechanism. The sliding mechanism is used to move the mobile vertical pipe 12 along the support disc frame 8. A bottom cover 13 is screwed on the bottom of the mobile vertical pipe 12. A magnifying camera 14 is embedded in the center of the bottom of the bottom cover 13. The transmission line of the magnifying camera 14 passes through the mobile vertical pipe 12 and is connected to an external display. The transmission line can be customized according to actual needs. A fill light 15 is evenly embedded in the bottom of the bottom cover 13 and located on the periphery of the magnifying camera 14. The fill light 15 is a ring-shaped LED fill light. The wire drum of the fill light 15 is fixedly set on the inner bottom of the bottom cover 13, and the power line connected to the wire drum passes through the mobile vertical pipe 12 and is connected to an external DC power supply.

[0026] Therefore, under the action of the rotating mechanism, the doctor can rotate the magnifying camera 14 to different directions to capture and shoot the image reflected by the side prism of the gonioscope 2, and through the cooperation of the supporting disc frame 8 and the sliding mechanism, the magnifying camera 14 can capture and shoot the image reflected by the side prism of the gonioscope 2 at different inclination angles.

[0027] The sliding mechanism and the movable standpipe 12 are also provided with an elastic support mechanism, which is used to elastically support the movable standpipe 12 .

[0028] Under the action of the elastic pressure support mechanism, the distance adjustment of the magnifying camera 14 is realized to meet the needs of capturing the room angle image at different distances.

The two ends of the spring 17 are elastically supported on the veneer slider 11 and the pressure cover 16. In the natural state of the spring 17, the top of the bottom cover 13 is pressed on the veneer slider 11 below. One finger hooks the support disc frame 8, and the other finger presses on the pressure cover 16 to press down the pressure cover 16 to adjust the distance between the magnifying camera 14 and the light-transmitting mirror 4; a soft cover 18 is sleeved on the spring 17. The material of the soft cover 18 is natural rubber. The two ends of the soft cover 18 are fixed to the pressure cover 16 and the veneer slider 11 with adhesive. The setting of the soft cover 18 can not only block the contact between the external environment and the spring 17, but also limit the pressure cover 16 from escaping from the mobile riser 12.

[0034] The working principle of this embodiment is as follows:

[0035] When in use, hold the handle 3, align the bottom mirror surface of the goniometer 2 with the center of the patient's cornea, and by rotating the rotating ring 5 and moving the movable standpipe 12 along the arc direction of the support plate frame 8, the side prism refracted image of the goniometer 2 can be captured at different angles and orientations through the magnifying camera 14. One finger hooks the support plate frame 8, and the other finger presses on the pressure cover 16, and the pressure cover 16 is pressed down to adjust the distance between the magnifying camera 14 and the light-transmitting mirror surface 4;
