Abstract

The invention discloses a pathological mucosa tissue stainer, which comprises a shell, wherein an inner cavity is formed in the shell; a staining fluid is arranged below the inner cavity; the bottom of the inner cavity is provided with a liquid flow hole; a one-way valve is arranged on the liquid flow hole; the bottom of the shell is connected with a liquid absorbing material; the top of the staining fluid is provided with a sealing piece; the surface of the inner cavity is in hermetic fit with the outer surface of the sealing piece; the upper part of the sealing piece is connected with the lower end face of an elastic body; the upper end face of the elastic body is connected with lower surface of a pressing handle; and the one-way valve is an elastic sheet which is arranged at the upper end of the liquid flow hole or an elastic rubber piece arranged on the liquid flow hole. The pathological mucosa tissue stainer has a simple and reliable structure, and is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pathological mucosal tissue stainer used for sampling pathological mucosal early cancerous tissue specimens. Background technique [0002] With the continuous development of diagnostic methods such as endoscopy and imaging, early detection and early treatment of tumors has become an important means of tumor diagnosis and treatment, and more and more patients with precancerous lesions and early cancers have been diagnosed (such as esophagus, stomach, intestines, etc. parts). The collection of specimens of early cancer lesions has always been the key point and difficulty in the collection of gross specimens, because the lesions are often not obvious, and sometimes only show changes such as small uplifts, small depressions, or roughness of the mucosa. , Sometimes the surgeon uses silk thread to mark, and there will be a certain deviation. If there is no surgeon’s marker, ...
