Abstract

The invention relates to a living body sampler and a drill applicable to the living body sampler. The living body sampler comprises a handheld drill gun, wherein a sampling insertion tube is mounted on a housing of the handheld drill gun; the handheld drill gun is provided with a rotating gun head; a sampling insertion rod is mounted on the rotating gun head and located in the sampling insertion tube; the sampling insertion rod and/or the sampling insertion tube are/is detachably connected with the handheld drill gun; a drill is arranged at the front end of the sampling insertion rod and comprises a drill shaft and at least one cutting blade arranged at the end part of the drill shaft; cutting edges of the cutting blades extend outwards from an axis of the drill shaft radially and achievecutting through the end faces of the cutting edges; the cutting edges of the cutting blades come out of the sampling insertion tube; and a sample storage cavity for accommodating tissue and organ samples is defined by the drill on the inner sides of the cutting blades, and the sampling insertion tube. The living body sampler achieves cutting and sampling through rotation of the adapted drill; thedrill can be clung to the surface of an organ for sampling; and therefore, injuries to the living body organ are reduced.

Description

technical field [0001] The invention relates to a living body sampler and a drill bit suitable for the living body sampler. Background technique [0002] The metabolic state of tissues and diagnostics and therapeutics are developing areas of research, currently obtained by obtaining tissue samples for subsequent sampling or testing. There are many ways to obtain tissue samples. In order to ensure the validity and real-time performance of sampling, living body sampling is mostly carried out, which puts forward higher design and manufacturing requirements for samplers used for living body sampling. [0003] The Chinese utility model patent with the authorized notification number CN204789014U discloses a tissue sampler. The tissue sampler includes a needle core sampling assembly extending in the front and rear directions. The front end of the needle core is provided with a needle head, the rear end of the needle core is set with a return spring for applying a forward force to ...
