ORGAN SAMPLING INSTRUMENT.

摘要

An instrument for taking samples from internal organs of humans and animals in which a cannula for insertion into the organ is detachably connected to a handle portion provided with a plunger pump for drawing the sample into the cannula and a needle of homogeneous material is secured in the pump plunger for axial movement within the cannula and serves to prevent undesired fragments of connective tissues entering the cannula when the cannula passes through the tissues surrounding the internal organ being sampled.
