Abstract
The utility model relates to the field of medical devices, in particular to a body surface tumor sampler which is reasonable in structure and convenient to use and can improve working efficiency of medical workers and reduce patients' pains. The body surface tumor sampler comprises a needle tube, a needle handle, a piston and a needle head, wherein the needle head is connected with the front end of the needle tube, the needle handle is connected with the piston, and the piston is located in the needle tube and is pulled through the needle handle to enable negative pressure to be formed in the needle tube. The body surface tumor sampler is characterized in that the front end of the needle head is provided with a groove, the side edge of the groove is provided with a knife edge, a needle core is further arranged in the needle tube, the front end of the needle core is provided with a scraper, and the tail end of the needle core penetrates through the piston to be connected with the needle handle. Compared with the prior art, the body surface tumor sampler can effectively solve the problem that a tumor sample is difficult to sample and has the advantages of being reasonable in structure and simple and convenient to operate, enabling a wound to be small, and being capable of remarkably improving working efficiency of the medical workers and reducing the patients' pains.
Description
Technical field
This utility model relates to medical instruments field, and is specifically a kind of rational in infrastructure, easy to use, can improve medical personnel's work efficiency, and reduces patient suffering's body surface tumor sampler.
Background technology
As everyone knows, can successfully realize by operative incision when carrying out the body-surface tumor active check sampling to patient clinically, but because wound is large, the misery of bringing to the patient is large, mostly adopt at present syringe to take a sample for this reason, the negative pressure that produces when aspirating by it, draw tumor tissues, although this sampling method has the little advantage of wound, the ordinary syringe syringe needle is round and smooth, the pin chamber is narrow, be not easy to be isolated after drawing tissue to be checked, after the absorption, to be checkedly organize and enter the pin intracavity, be difficult to take out, increased work difficulty to the medical worker.
Summary of the invention
This utility model is for the shortcoming and defect that exists in the prior art, proposes a kind of rational in infrastructurely, easy and simple to handle, can significantly improve medical personnel's work efficiency, reduces patient suffering's body surface tumor sampler.
This utility model can reach by following measures:
A kind of body surface tumor sampler, comprise needle tubing, needle handle, piston, syringe needle, wherein syringe needle is connected with the needle tubing front end, and needle handle is connected with piston, and piston is positioned at needle tubing, needle handle pulling piston makes and forms negative pressure in the needle tubing, it is characterized in that the syringe needle front end is provided with groove, the lateral edges of groove is provided with blade, also is provided with nook closing member in the needle tubing, the front end of nook closing member is provided with scraper, and the end of nook closing member passes piston and is connected with needle handle.
The scraper of nook closing member front end is triangle in this utility model, and the lateral edges of scraper is provided with blade, is used for thrusting tumor tissues, and will treats that sample thief is from the tissue separation.
The syringe needle front end can be provided with two grooves in this utility model, and the lateral edges of groove is equipped with blade, is used for cutting treating the sampling tissue, improves medical personnel's work efficiency.
This utility model in use, medical personnel hand needle tubing, nook closing member is pushed in the syringe needle of needle tubing front end by needle handle, then syringe needle is thrust tumor tissues, after by needle handle nook closing member outwards being pushed again this moment, scraper by the nook closing member front end will separate tissue be taken a sample, then spur needle handle, making it drive piston moves in needle tubing, make and form negative pressure in the needle tubing, this moment, separated sample entered needle tubing through syringe needle under the effect of negative pressure, and the groove of syringe needle front end can further improve the sampling efficiency of sample.
This utility model compared with prior art can effectively solve tumor sample sampling hard problem, has rational in infrastructurely, easy and simple to handle, and wound is little, can significantly improve medical personnel work efficiency, reduce the significant advantage such as patient suffering.
Description of drawings:
Accompanying drawing 1 is structural representation of the present utility model.
Reference numeral: needle tubing 1, needle handle 2, piston 3, syringe needle 4, groove 5, nook closing member 6, scraper 7.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described.
A kind of body surface tumor sampler, comprise needle tubing 1, needle handle 2, piston 3, syringe needle 4, wherein syringe needle 4 is connected with needle tubing 1 front end, and needle handle 2 is connected with piston 3, and piston 3 is positioned at needle tubing 1, needle handle 2 pulling pistons 3 make needle tubing 1 interior formation negative pressure, it is characterized in that syringe needle 4 front ends are provided with groove 5, the lateral edges of groove 5 is provided with blade, also is provided with nook closing member 6 in the needle tubing 1, the front end of nook closing member 6 is provided with scraper 7, and the end of nook closing member 6 passes piston 3 and is connected with needle handle 2.
The scraper 7 of nook closing member 6 front ends is triangle in this utility model, and the lateral edges of scraper 7 is provided with blade, is used for thrusting tumor tissues, and will treats that sample thief is from the tissue separation.
This utility model in use, medical personnel hand needle tubing 1, nook closing member 6 is pushed in the syringe needle 4 of needle tubing 1 front end by needle handle 2, then syringe needle 4 is thrust tumor tissues, after by needle handle 2 nook closing member 6 outwards being pushed again this moment, scraper 7 by nook closing member 6 front ends will separate tissue be taken a sample, then spur needle handle 2, make it drive piston 3 in needle tubing 1 interior motion, make needle tubing 1 interior formation negative pressure, this moment, separated sample entered needle tubing through syringe needle 4 under the effect of negative pressure, and the groove 5 of syringe needle 4 front ends can further improve the sampling efficiency of sample.
This utility model compared with prior art can effectively solve tumor sample sampling hard problem, has rational in infrastructurely, easy and simple to handle, and wound is little, can significantly improve medical personnel work efficiency, reduce the significant advantage such as patient suffering.
