Embodiment Construction

[0023] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0024] see Figure 1-Figure 6 , the biopsy sampling instrument given in this example has both the functions of a biopsy needle and a brush, and its composition mainly includes a handle moving part 1, a handle fixing part 2, an outer sheath 3, an inner sheath 5, a needle 6, and a cannula 9 , connecting pipe 10, protective wire 11.

[0025] Here, the handle moving part 1, the handle fixing part 2 and the sleeve 9 cooperate to form a corresponding handle assembly. The handle fixing part 2 is the basic component of the biopsy sampling instrument, and is preferably a multi-stage cylindrical structure as a whole. As an example, the handle fixing member 2 as a whole is a two-stage cylindrical structure composed of a small end and a large end.

Abstract

The invention discloses a biopsy sampling instrument. The biopsy sampling instrument comprises a handle assembly, an outer sheath tube and an inner core assembly, wherein the outer sheath tube is connected with the handle assembly through a channel; the inner core assembly is movably arranged in the outer sheath tube; the needle head of the inner core assembly is connected with a moving piece in the handle assembly to form a negative-pressure channel; and a brush and/or needle head can move relative to the outer sheath tube out of the outer sheath tube or retracted into the outer sheath tube under the drive of the moving piece in the handle assembly. The biopsy sampling instrument provided by the invention has functions of a biopsy needle and a brush, and mucosa deep-layer tissue puncturebiopsy and surface mucosa biopsy are realized through the instrument.

Description

technical field [0001] The invention relates to a medical device, in particular to a scheme of a biopsy sampling needle in endoscopic diagnosis and treatment technology. Background technique [0002] Endoscopic biopsy is a method for sampling lesion tissue through endoscopic forceps for pathological detection. This technique achieves the acquisition of cells, tissues, and body fluids for diagnostic specimens through puncture, and is especially widely used in the biopsy of lung lesions. Currently, the commonly used negative pressure biopsy needles are mainly aimed at the biopsy of submucosal deep tissues, but for the sampling of mucosal superficial tissues, the existing biopsy needles have great limitations. [0003] The endoscopic brush implements the acquisition of diagnostic specimens of cells, tissues, and body fluids by brushing. It is mainly aimed at sampling mucosal surface cells, tissues, and body fluids, but cannot achieve biopsy of deep mucosal tissues. [0004] A...
