Compared with the prior art, the tumour tissue sampler has the characteristics that the structure is simple, the operation is convenient, the pain of a patient is relieved, etc.

Description

A kind of novel tumor sample of tissue device

Technical field

This utility model relates to a kind of medical device, especially a kind of novel tumor sample of tissue device, and that this sampler has is simple in structure, easy to operate, alleviate characteristics such as patient suffering.

Background technology

Generally adopt cytolgical examination method or histological examination method that tumor is checked clinically, the cytolgical examination method is to do inspection with the cell of entry needle absorption affected area, in the operating process because pin hole is less and have a bigger negative pressure, be easy to cause pin hole to stop up, it is less to cause drawing thing, influences check result; The histological examination method is to cut little block organization by operation to check, has brought great misery to the patient.

The utility model content

Technical assignment of the present utility model is to provide a kind of novel tumor sample of tissue device at above-mentioned deficiency of the prior art.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of novel tumor sample of tissue device comprises sampling probe, wherein, the sampling probe top is needle-like, one side is provided with back-shaped barb on the sampling probe top, and with sleeve pipe, sleeve pipe can slide relatively with sampling probe on the sampling probe surface.

The beneficial effect that the utlity model has is:

1, simple in structure, with low cost, easy to operate, safe and reliable.

The hardship of 2, alleviate the patient suffering, exempting patient's operation improves medical personnel's work efficiency.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

With reference to Figure of description this utility model is done following detailed description the in detail:

As shown in the figure, this utility model comprises sampling probe 1, the top of sampling probe 1 is acicular texture, be similar to the syringe needle position of entry needle, a side has back-shaped barb 2 on the top of sampling probe 1, surface at above-mentioned sampling probe 1 has sleeve pipe 3, and back-shaped barb 2 is positioned at sleeve pipe 3 inboards, and sleeve pipe 3 can slide relatively with sampling probe 1.

During clinical manipulation, sampling probe 1 and sleeve pipe 3 are together thrust subcutaneous to the lump surface and advance a little, with hands fixed sleeving 3, continue to thrust sampling probe 1 in the lump then, sampling probe 1 is rotated to an angle, rely on back-shaped barb 2 to take off together tissue, more back-shaped barb 2 is retreated to together to extract in the sleeve pipe 3 and get final product, time saving and energy saving, as to have exempted patient's operation hardship.

Claims (1)

1. A kind of novel tumor sample of tissue device comprises sampling probe, it is characterized in that described sampling probe top is needle-like, and one side is provided with back-shaped barb on described sampling probe top, and with sleeve pipe, described sleeve pipe can slide relatively with sampling probe on described sampling probe surface.
