In order to make the cut tissue take out, the utility model is a preferable proposal: the clearance between the edge of the spiral blade and the inner wall of the coaxial outer sleeve is less than 0.1 mm.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the spiral blade arranged on the puncture biopsy needle can be used for sampling tissue while the puncture biopsy needle is rapidly inserted into a focus, and can be matched with the coaxial outer sleeve to rapidly sample living tissue, so that the subsequent surgical pathology examination is facilitated;
2) by the aid of the thread adjusting sleeve, the penetration depth of the biopsy needle can be adjusted by rotating the thread adjusting sleeve, flexible sampling of tissues with different depths is achieved, and practicability of the biopsy needle is improved;
3) the rotary sleeve is detachably connected with the thread of the cap body, so that the puncture biopsy needle can be quickly pulled out from the coaxial outer sleeve by the rotary sleeve and the thread adjusting sleeve, and subsequent tumor treatment is facilitated.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a screw-tupe aspiration biopsy needle, including aspiration biopsy needle 1, the bottom outer wall of aspiration biopsy needle 1 is equipped with spiral sword 11, the top of aspiration biopsy needle 1 is equipped with external screw thread mouth 12, the outside cover of aspiration biopsy needle 1 is equipped with the top fixedly connected with cap body 21 of 2 coaxial overcoat 2 of coaxial overcoat, the top threaded connection of cap body 21 has rotary sleeve 3, the top of rotary sleeve 3 is rotated and is connected with screw thread adjusting sleeve 4, 4 inner walls of screw thread adjusting sleeve are equipped with internal thread mouth 41, internal thread mouth 41 and external screw thread mouth 12 threaded connection.
In this embodiment: the inner wall of the rotary sleeve 3 is provided with an annular groove 31, and the annular groove 31 is rotatably sleeved with an annular sleeve 42 arranged at the bottom end of the thread adjusting sleeve 4.
Specifically, the annular groove 31 is rotationally matched with the annular sleeve 42, so that the threaded adjusting sleeve 4 is prevented from being separated from the rotary sleeve 3 when being rotated.
In this embodiment: the thread adjusting sleeve 4 is made of transparent plastic materials, and a transparent dustproof cover is covered at the top of the thread adjusting sleeve 4.
