Problems solved by technology

The shortcoming of this kind of trephine is that: there is no scale on the trephine knife, which makes it difficult to control the depth of material collection. If the depth is not enough, it will cause the failure of material collection; the operation of the trephine drill is manual spiral into the skin, which is very random. , the accuracy is not enough

Embodiment Construction

[0012] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0013] A skin biopsy device comprises a circumcision knife 1, a solid knife handle 2 and a pressing operation table. It is characterized in that: the pressing operation platform is composed of a slope plate 3 , a horizontal plate 5 , a fixed pillar 6 and a pressing plate 4 . Circumcision knife 1 and solid knife handle 2 are connected by threaded buckle, and solid knife handle 2 is fixedly connected on the top of pressing console slope plate 3, and pressing plate 4 is hinged on the top of fixed pillar 6. Described ring cutting knife 1 length is 1.5-2cm, and scale is set around the ring cutting knife, divides No. 2, No. 4, No. 6, No. 8 four kinds of ring cutting knives for optional disassembly according to the ring cutting knife blade diameter...

Abstract

The invention provides a skin tissue pathology sample collecting tool, relates to a skin biopsy device, and belongs to the technical field of medical apparatus. The skin biopsy device comprises a ring cutter, a solid handle and a pressing operation table. The ring cutter and the solid handle are detachably fastened in a threaded manner. Scale marks are formed on the periphery of the ring cutter. By the structure, the ring cutter can be demounted according to needs, and ring cutters of different types can be selected according to needs. Sampling is a mechanical operation utilizing the lever principle, so that randomness of manual rotation of traditional trephine is lowered, and accuracy and sampling success rate are increased.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a skin biopsy device, a tool for collecting skin histopathological samples. 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. Currently, there are three methods for skin sample collection: surgical excision, trephination 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, which are limited in clini...
