Abstract
A puncture needle for cytopathology examination comprises a puncture tube and is characterized in that a cutter is arranged in the puncture tube which is provided with a sampling aperture at the front end and with a handle at the rear end, the front end of the cutter has a semicircular shape, and the rear end of the cutter is a handle. When the puncture needle is used, the sampling aperture disposed at the front end of the puncture tube punctures into a tumor, tumor tissues fall in the sampling aperture, the handle of the cutter is turned at this time, the semicircular cutter fall into the tumor tissues in the sampling aperture, and the tumor tissues are cut off. The beneficial effects of the puncture needle of the utility model are simple structure, convenient operation, small cut, pain decrease for patients, workload reduction for medical staffs and operating efficiency enhancement.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of cytopathology inspection puncture needle.
Background technology
At present, as everyone knows, use puncture needle to do clinically to get cell and tissue specimen carries out pathological examination, being the important means for diagnosing tumour character, mainly is to adopt puncture needle at present, but because its needle point is beveled edge, can not effectively cut tissue, so, in the process of drawing materials of this type of specimen, be difficult to obtain effective tissue specimen.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of cytopathology inspection puncture needle simple in structure, easy to use is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of cytopathology inspection puncture needle, it comprises puncture tube, it is characterized in that: be provided with cutter in the described puncture tube, described puncture tube front end is provided with thief hole, the rear end is provided with handle, the cutter front end is semicircle, and the rear end is a handle.The thief hole that only needs during use the puncture tube front end is provided with is punctured in the tumor, and tumor tissues will be trapped in the thief hole, at this moment rotates the handle of cutter, and semicircular cutter will cut down the tumor tissues that is trapped in the thief hole.
The beneficial effects of the utility model are: simple in structure, easy to operate.Otch is little, has alleviated patient's misery, has reduced medical personnel's workload, has improved work efficiency.
Description of drawings
Below in conjunction with accompanying drawing this utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
