The invention discloses a system and a method of a handhold slit lamp, relating to the field of an optical instrument. The system and the method of the handhold slit lamp are used for solving the problem that the slit lamp is not convenient to carry and use. The system of the handhold slit lamp comprises a handhold shell mechanism, a focusing lens, a diaphragm, a light spot adjusting part, a crack cutter blade, a dodging device, a light source, a driving circuit, a power supply device, and a switch device, wherein all or a part of the focusing lens, the diaphragm, the light spot adjusting part, the crack cutter blade, the dodging device, the light source, the driving circuit, and the power supply device are arranged on an axes of the handhold shell mechanism; preferably, the switch device is arranged at the tail part of the handhold shell mechanism; preferably, a semiconductor lighting light emitting diode (LED) device can be used in the light source. The system and the method of the handhold slit lamp are mainly used for the daily ophthalmic testing of doctors, especially for work round or visit the ophthalmic testing of the doctors; and the system and the method are mainly used for checking the organizations of the former section such as cornea, iris, and crystal and the like of patient's eye.
Description
technical field [0001] The invention relates to the field of optical instruments, in particular to a hand-held slit lamp system. Background technique [0002] The current slit lamp microscopes are mainly desktop slit lamp microscopes, which are bulky and difficult to carry around. Even if there are hand-held slit lamps, most of them use halogen tungsten lamps with linear filaments. The service life of this light source is relatively short, generally only 200-300 hours. The cost of use is high, and the light source needs to be replaced frequently, which brings many additional operations. When focusing or adjusting the width of the light source, it generally requires two-handed operation to complete. One hand holds the hand-held slit lamp, and the other hand adjusts the light source slit. [0003] The existing slit lamp system still has the following defects: [0004] Common flaws: [0005] 1. It is large in size and heavy in weight, making it difficult to carry it around....
