Abstract

The invention discloses a percutaneous puncture catheter needle, which comprises a needle tube. The end of the needle tube is integrally provided with a needle sleeve, a needle head is tightly inserted into the needle sleeve, the end of the needle head is integrally connected with a needle core, the needle core is provided with a marking area, the end of the needle core extends out of a push block1 and is integrally provided with a push block 2, one end, deviated from the push block 2, of the push block 1 is integrally connected with a handle, and one end, deviated from the push block 1, of the handle is sleeved with a rubber plug. By adopting a mode of using a syringe to extract the negative pressure, a tumor sample is intercepted, after the required sample is intercepted, pulling is stopped, the needle tube is withdrawn from the body, the push block 1 is pushed, so that the tumor sample in the needle tube and the needle sleeve can be extruded out to be tested.

Description

technical field [0001] The invention relates to the technical field of catheter needles, in particular to percutaneous puncture catheter needles. Background technique [0002] When a tumor patient tests a lesion sample, the lesion sample needs to be taken first. Currently, the hospital has used it, and there are great defects.
