technical field

The utility model belongs to the technical field of medical equipment, in particular to a biopsy sample transfer device.

Background technique

Sampling of biopsy specimens is often required during endoscopy. Sampling forceps (biopsy forceps) are inserted through the lumen of the endoscope, and the sample to be tested is clamped down. After the sampling forceps are pulled out, the sample on the sampling forceps needs to be transferred to the sample bottle, and then sent to the laboratory for testing.

There is currently no tool specifically designed to remove or pick a sample from the biopsy forceps and load it into a vial, typically a broken toothpick is used to pick the sample and transfer it into a vial.

In the actual use process, there is a situation that the sample is dropped due to unstable picking, which causes huge troubles to the subsequent detection work.

Utility model content

The purpose of this utility model is: to provide a biopsy sample transfer device, grab the fork cap through the grasping mechanism, and then use a number of fork caps to fork the sample, and the fork needle is multiple , the fork is more stable, and the volume of the grabbing mechanism is larger than that of the fork cap, which is easy to operate.
