Embodiment Construction

[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0028] The specific embodiment of the living body sampler with replaceable sampling head provided by the present invention, such as Figure 1 to Figure 6 As shown, the living body sampler with a replaceable sampling head includes a hand-held drill gun 1, which forms a hand-held frame for the operator to hold. A sampling plunger 5 is connected to the position of the rotating gun head of the gun 1, and a sampling head is replaceably installed at the end of the sampling plunger 5, and the sampling head has a space for accommodating tissue samples. In this embodiment, the sampling head is a drill bit 3 detachably mounted on the end of the sampling plunger 5 away from the hand-held drill gun 1 . The sampling insert 4 is sheathed outside the sampling insert 5 , and can move axially relative to the sampling insert 5 , so that the length of the drill bit 3 expo...

Abstract

The invention relates to a living body sampler of which a sampling head is replaceable. The living body sampler of which the sampling head is replaceable comprises a handheld frame, wherein a samplinginserting pipe is mounted on the handheld frame; a sampling inserting rod is mounted in the sampling inserting pipe; the sampling inserting pipe can move in an axial direction relative to the sampling inserting rod; the sampling head is mounted at the end of the sampling inserting rod in a replaceable manner; and the sampling head is provided with an accommodating space for accommodating tissue samples. According to the living body sampler of which the sampling head is replaceable disclosed by the invention, after each sampling is completed, the sampling head is replaced, so that the occurrence of the situation that cross-infection is generated between different living bodies is avoided; the replaced sampling head can be integrally put in a freezing vessel for storage, so that in the removing process, the sterile requirements are guaranteed, and an operator can easily collect the desired tissue samples; and the living body sampler is very practical.

Description

technical field [0001] The invention relates to the technical field of instruments for sampling living cells, in particular to a living body sampler with a replaceable sampling head. Background technique [0002] Due to the clinical needs of scientific research and disease diagnosis, it is often necessary to sample animal tissues in vivo, such as liver, kidney, breast, muscle and tumor tissues. In the prior art, samplers are mostly used to collect and sample animal tissues that need to be collected . [0003] For example, a tissue sampler disclosed in a Chinese utility model patent with the authorized announcement number CN204789014U, the tissue sampler includes a needle core sampling assembly extending in the front and rear directions, and the needle core sampling assembly includes a needle core that guides the mobile suit along the front and rear direction and The needle tube has a needle head at the front end of the needle core, and a return spring for applying forward f...
