Dermatoscope

Abstract

The invention discloses a dermatoscope. The dermatoscope comprises a main body. The main body is provided with a mounting cavity, and a plurality of LED lights are connected in parallel in a circuit,and an anode and a cathode are respectively led out through wires. By turning on an external power source, the current of a first electromagnet and a second electromagnet is adjusted through a slide rheostat to change the position of a mounting tube and further coarsely adjust the distance between a light source and a lens to the skin. When a better imaging effect needs to be further achieved, a user only needs to rotate a knob manually according to the angular scale groove. Due to the fixed connection between the knob and a protection tube, a lens base can move up and down under the effect ofa first sliding rod with rotating of the protection tube, so as to finely adjust the distance between the light source and the lens to the skin, and achieve the aim of accurate imaging.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to a dermatoscope. Background technique [0002] Dermoscopy is a non-invasive diagnostic device applied on the human body. It can magnify the skin and observe the color and structure of the epidermis, dermis and dermis junction and dermal papilla. It is often difficult for the naked eye to wipe these colors and structures. Significantly improve the accuracy of clinical diagnosis of melanocytic, non-melanocytic and various benign and malignant skin lesions. Compared with simple routine clinical examination, the diagnostic accuracy of melanoma can be increased by 20% to 30%. [0003] In the prior art, the lens of the dermatoscope is the lens of the prior art, but the distance between the light source and the lens and the skin cannot be adjusted according to the needs of the existing lens, and thus the imaging cannot be performed accurately, which hinders the observation work of the st...
