Embodiment 1

[0026] Embodiment 1: A kind of disposable skin biopsy collector

[0027] Disposable skin biopsy collectors such as figure 1 , 2 shown.

[0028] The upper opening of the rigid ring drill bit (1) is a sharp blade with a high outside and a low inside. The vertical thickness of the steel is less than 0.5mm. 15mm, 4mm, 25mm for the fourth piece; the lower end of the ring bit is inserted and fixed in the drill groove in the upper circular surface of the plastic fixing piece (2). The fixing piece is a circular piece made of engineering plastics, 4 types The plastic fixing parts are all in the shape of a cylinder with the same size, with a height of 9mm, an outer diameter of 6mm, an inner diameter of the upper opening of 2mm, and an inner diameter of the lower opening of 3mm-4mm. Both the rigid ring bit (1) and the fixing part (2) can be molded at one time, and need to be tightly connected, sterilized at high temperature and high pressure, and sealed and packaged in a plastic bag. ...

Abstract

The invention provides a disposable biopsy collector and sampling device used for pathology biopsy sampling of clinic epithelium skin tissue or tumour tissue; the disposable biopsy collector and sampling device employs a rigid trephine head to match with negative pressure effect of a syringe in usage, so the obtained sample is tidy in edge, thus ensuring medicine inspection tissue integrity, improving sample quality, reducing operation time, and reducing operation technical difficulty; the operation can be done in a clinic, thus improving biopsy sampling efficiency, and the disposable device can prevent iatrogenic infection; a medicine ingot is configured so as to ensure healing, so usage is convenient. The disposable biopsy tissue pathology sampling tool belongs to the medical equipment, is simple in structure, convenient and efficient, low in cost, and safe and healthy.

Description

technical field [0001] The invention provides a disposable biopsy collector and a sampling device, which are medical disposable biopsy pathological sample collection tools, and can be used for pathological sample collection of skin tissue biopsy or tumor tissue biopsy. It belongs to the field of medical equipment. Background technique [0002] The collection of skin pathology specimens is a common operation in skin pathology diagnosis or skin biopsy. Diagnosis and treatment of skin diseases, especially for difficult skin diseases, usually requires skin histopathological examination. Current indications for skin biopsy in dermatology include skin tumors and precancerous diseases, leprosy and skin tuberculosis, bullous skin diseases and allergic vasculitis, skin diseases with pathogens, skin with relatively specific histological changes Diseases, some inflammatory skin diseases with certain specific lesions, etc. At present, skin histopathological specimens are collected, t...
