Description

Technical Field

[0001] The utility model relates to the technical field of in vitro medical instruments, in particular to an adjustable auxiliary device for skin biopsy. Background Art

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items, including the necessary computer software, that are used directly or indirectly on the human body, for the purpose of diagnosis, prevention, monitoring, treatment or relief of disease; diagnosis, monitoring, treatment, relief or functional compensation of injury; inspection, replacement, regulation or support of physiological structures or physiological processes; support or maintenance of life; pregnancy control; and providing information for medical or diagnostic purposes by examining samples from the human body.

[0003] Currently, when diagnosing skin diseases that are difficult to clearly diagnose with the naked eye, a biopsy is performed on the patient's affected area, and then the sample is pathologically diagnosed to determine the disease. There are two common methods for skin sampling: one is to directly cut the biopsy with a scalpel, and the other is to use a circular trephine, which has a circular cutting knife at the front end. In both methods, after cutting the skin tissue with a scalpel or a circular cutting knife, the cut skin tissue is separated with surgical scissors, and then the skin tissue is clamped with tweezers and placed on the surgical tray to complete the skin tissue sampling. However, the tweezers have thick tweezers, and the clamping force depends entirely on the doctor's experience. It is very easy to damage the skin tissue, affecting the subsequent pathological examination of the skin tissue, and it is relatively inconvenient to use.

[0004] In view of the above technical deficiencies, an adjustable auxiliary device solution for skin biopsy is proposed. Utility Model Content
