Abstract

The invention provides a knife rest and light source structure of a slit lamp. The structure comprises a light-pervious cylinder structure and a light source base structure connected with the lower end of the light-pervious cylinder structure. The light-pervious cylinder structure comprises a triangular prism, a light-pervious cylinder lens cone, a first lens, an upper lens space ring and a second lens. The first lens, the lens space ring and the second lens are sequentially arranged in the light-pervious cylinder lens cone from top to bottom. The triangular prism is arranged on the top of the lens cone. The light source base comprises an upper blue-ray disc, a lower blue-ray disc, an opening and closing knife rest, a third lens, a lower lens space ring, a fourth lens, a light source lens cone, a bulb and a lamp holder. The upper blue-ray disc is located on the lower blue-ray disc. The light source lens cone is sleeved with the opening and closing knife rest. The third lens, the lower lens space ring and the fourth lens are sequentially arranged in the light source lens cone from top to bottom. The bulb is arranged on the upper surface of the lamp holder. The lamp holder is arranged at the bottom end of the light source lens cone. The knife rest and light source structure of the slit lamp is compact in structure and convenient to use and can effectively reduce the size of the slit lamp.

Description

technical field [0001] The invention relates to a knife holder and a light source structure of a slit lamp used in the field of medical instruments. Background technique [0002] The slit lamp microscope is a conventional ophthalmic optical inspection equipment. It not only enables the doctor to observe the superficial lesions of the detected person's eyes very clearly, but also can clearly show the lesions in the deep tissues of the eye by adjusting the focus and the width of the light source. . [0003] The slit lamp microscope consists of an illumination system and a microscope observation system. The lighting system is used to provide appropriate light to the eyes of the person being tested (hereinafter referred to as the subject's eye) to illuminate the subject's eye; the microscope observation system is used to clearly present the crack image of the subject's eye so that the doctor can observe The crack image understands the internal situation of the eye to be inspec...
