Description

Technical Field

[0001] The utility model relates to the technical field of dermatoscopes, in particular to an ultrasonic dermatoscope. Background Art

[0002] A dermatoscope, also known as a skin light transmission microscope, has the same function as an ophthalmoscope used in ophthalmology and an otoscope used in otolaryngology. It is an instrument used to observe skin pigmentation diseases. A dermatoscope is a non-invasive diagnostic device used on the human body. It can magnify the skin and observe the color and structure of the epidermis, dermis, dermal junction and dermal papilla. It is essentially a skin microscope that can magnify dozens of times. These colors and structures are often difficult to observe with the naked eye. A dermatoscope can significantly improve the clinical diagnostic accuracy of melanocytic, non-melanocytic and various benign and malignant skin lesions. Compared with simple routine clinical examinations, the diagnostic accuracy of melanoma can be significantly improved.

[0003] Prior art CN208725705U discloses a dermatoscope, comprising a main mirror body, a mounting cavity is provided on the main mirror body, and a plurality of LED lights are connected in parallel in a circuit, wherein the positive and negative poles thereof are led out respectively through wires. By connecting to an external power supply, a sliding rheostat is used to adjust the current passing through the first electromagnet and the second electromagnet, thereby changing the position of the mounting tube, thereby coarsely adjusting the distance between the light source and the lens and the skin. When it is necessary to further achieve a better imaging effect, it is only necessary to manually rotate the knob according to the angular scale groove. Since the knob is fixedly connected to the protective tube, as the protective tube rotates, the lens base is moved up and down by the action of the first slide bar, thereby fine-tuning the distance between the light source and the lens and the skin, thereby achieving the purpose of accurate imaging. However, the above-mentioned dermatoscope does not have deep imaging capabilities, and cannot observe the morphological characteristics of subcutaneous tumors, the degree of invasion of the skin, and the depth of the lesion.

[0004] Therefore, there is an urgent need to provide an ultrasonic dermatoscope that can combine deep imaging capabilities and surface detail observation capabilities compared to existing technologies, and provide more comprehensive lesion information. Utility Model Content
