Biopsy sample transfer device

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to biopsy sample transfer device.

Background

In endoscopy, it is often necessary to take a sample of a biopsy specimen. The sampling forceps (biopsy forceps) are inserted into a lumen of an endoscope, the sample forceps at a part to be detected are clamped, after the sampling forceps are drawn out, a sample on the sampling forceps needs to be transferred to a sample bottle, and then the sample bottle is sent to a laboratory for testing.

Currently, there is no tool dedicated to removing or picking the sample from the bioptome and then loading it into the sample vial, typically using a broken toothpick to pick the sample and then transfer it into the sample vial.

In the actual use process, the condition that the sample falls due to unstable picking exists, and great troubles are caused to the subsequent detection work.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: aim at providing a biopsy sample transfer device, get the cap through snatching the mechanism and snatch the fork, get a plurality of forks of cap by the fork again and get to the sample and fork and get, the fork is got the needle and is many, and the fork is got more firmly, snatchs simultaneously the mechanism volume and gets the cap for the fork bigger, the operation of being convenient for.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows:

the utility model provides a biopsy sample transfer device, gets the cap and gets the cap with the fork and can dismantle the mechanism of snatching of being connected including the fork, the cap is got including connecting portion to the fork, the lower extreme of connecting portion evenly is equipped with a plurality of forks and gets the needle.

Further limited, the outer wall of the forking needle is provided with a plurality of grooves, and the grooves are inclined inwards from top to bottom.
