Abstract

The invention provides a skin tissue pathological specimen collection tool, relates to a press-type skin biopsy ring cutter, and belongs to the technical field of medical apparatus and instruments. The press-type skin biopsy ring cutter comprises a press handle, a center slide bar, a reset spring, an outer sleeve, a middle sleeve, a cutter bit sheath and a ring cutter bit. The press-type skin biopsy ring cutter is characterized in that the outer sleeve and the cutter bit sheath are respectively screwed onto the middle sleeve; the press handle and the ring cutter head are respectively screwed onto the center slide bar; the center slide bar is arranged in the middle sleeve through the reset spring. According to the press-type skin biopsy ring cutter provided by the invention, the cylindrical stalloy ring cutter bit is adopted, and the outer wall of the middle sleeve is provided with a depth dividing rule, and thus, a sampled specimen has a regular edge, and is in the shape of a standard cylinder; moreover, depth is controllable, so that the sampling success rate is greatly improved. The press-type skin biopsy ring cutter provided by the invention is reasonable in structural design, capable of enhancing the operational stability, shortening the operation time, reducing the pain of patients, simple and convenient in operational process, and suitable for being clinically popularized and applied.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a skin tissue pathological sample collection tool—a pressing type skin biopsy circumcision knife. Background technique [0002] At present, with the improvement of economic development and people's living standards, people pay more and more attention to the health requirements of their own skin. Skin histopathology is of great value for the diagnosis of skin diseases, and at the same time, it is of great significance for understanding the occurrence, development, outcome, general state of the body and the selection of treatment methods. In order to obtain high-value pathological pictures, regular specimens must be available. There are three methods of skin sample collection: surgical excision, trepanation, and paring. Among them, the surgical cutting method and the cutting method are to directly cut off the diseased skin with a scalpel to directly obtain samples, whic...
