Device for skin biopsy

Abstract

A skin biopsy device and a method of operating a skin biopsy device are disclosed. The skin biopsy device comprises a base member configured to be placed onto a skin surface; an cutting member configured to be received by the base member and to be movable relative to the base member in a direction substantially orthogonal to the skin surface; and an actuation member configured to drive the cutting member to travel a predetermined distance at a predetermined velocity in said direction.

Description

technical field [0001] The present invention relates broadly, but not exclusively, to devices for skin biopsy. Background technique [0002] A skin biopsy is a biopsy technique in which a skin lesion is removed and sent to a pathologist or dermatologist for microscopic diagnosis. Skin biopsy not only aids in diagnosis in difficult situations, but also provides an opportunity to detect abnormalities in routine practice. Because skin biopsies are often performed under local anesthesia, dermatologists may be challenged to select the correct lesion site and perform the biopsy with the correct technique to ensure good interpretation of the biopsy. Selection of classic, well structured, unmodified (by scraping or any topical application) lesion is the classic adage in skin biopsy. [0003] One of three types of skin biopsy is performed to assess the nature of the lesion. The first type of skin biopsy is a shave biopsy, in which a physician manually removes a thin layer of the l...

Problems solved by technology

However, current commercial blades for scar repair are often large and bulky

Also, the design and incision process takes most of the surgical time and the closure of the scar and healing of the wound usually takes about five to seven days for scars on the face

Therefore, imprecise incision and incision design may lead to unfavorable outcomes and delay operative time and wound healing
