Abstract
A back-pulling hook type biopsy needle comprises a puncturing needle and a sampling needle. Wherein, the sampling needle longer than the puncturing needle is socketed in the puncturing needle. At back end of the puncturing needle and sampling needle, a needle stand is provided respectively. The sides of the sharp end of the sampling needle are provided with two sampling recesses. At one side of the rear end of the puncturing needle stand, a recess is provided. At one side of the front end of the sampling needle stand, a lobe is provided, whose location and shape match with the recess at the rear end of the puncturing needle stand. Before using, the sampling needle is socketed in the puncturing needle. At using, first the puncturing needle is inserted into the surface of the pathologic position which shall be sampled, and then the sampling needle is pushed into the pathologic position to take a sample. After sampling, the sampling needle is returned into the puncturing needle, finally the whole biopsy needle retracts from one's body, so one biopsy sampling completes. The sampled amount got by the biopsy needle is enough for pathologic examination. The utility model is of reasonable design, simple structure, easy to manufacture and use, can be used for several times.
Description
One, technical field
This utility model relates to a kind of biopsy needle that is used for pathologic finding, particularly a kind of biopsy needle of falling the drag hook type.
Two, background technology
When doing inspection for tumour patient,, need get some living tissues from disease sites with biopsy needle in order to determine the character of tumor.The biopsy needle of usefulness is a kind of gun type of gas burner biopsy needle at present, and biopsy needle is pulled the spring trigger on the biopsy needle back seat after going in the tumor, discharges the control force to spring, by spring interior pin is had the living tissue biopsy needle of tumor and extracts out.This biopsy needle complex structure costs an arm and a leg, and every biopsy needle can only use once, causes significant wastage.The interior needle tip position of biopsy needle is provided with a groove, and the living tissue of taking-up is less, does pathologic finding sometimes inadequately and uses.
Three, summary of the invention
For overcoming the deficiencies in the prior art, it is a kind of reasonable in design, simple in structure, easy to manufacture, easy to use that this utility model provides, can nonexpondable biopsy needle of falling the drag hook type.
A kind of biopsy needle of falling the drag hook type is made up of puncture needle and sampling needle, and the sampling needle longer than puncture needle is sleeved in the puncture needle, and the rearward end of puncture needle and sampling needle is provided with a needle stand respectively, and the side at the most advanced and sophisticated position of sampling needle is provided with two sampling grooves.
Paracentesis needle holder rear end face one side is provided with a groove.
Sampling needle stand front end face one side is provided with a projection that adapts with Paracentesis needle holder rear end face upper groove position and shape.
Before the use, sampling needle is sleeved in the puncture needle.During use, earlier puncture needle is inserted the diseased region surface that needs sampling, sampling needle is pushed in the diseased region sample again, after the sampling, make and adopt pin to be back in the puncture needle, last whole biopsy needle withdraws from external, finishes biopsy sampling.The enough pathologic findings of this biopsy needle sampling quantity are used.
The utlity model has reasonable in design, simple in structure, easy to manufacture, easy to use, can nonexpondable characteristics.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Wherein, 1, puncture needle, 2, sampling needle, 3, the sampling groove, 4, Paracentesis needle holder, 5, the sampling needle stand, 6, groove, 7, projection.
Five, the specific embodiment
Embodiment: structure of the present utility model as shown in drawings, form by puncture needle 1 and sampling needle 2, be sleeved in the puncture needle 1 than puncture needle 1 long sampling needle 2, puncture needle 1 is provided with a needle stand 4 and 5 respectively with the rearward end of sampling needle 2, and the side at sampling needle 2 most advanced and sophisticated positions is provided with two sampling grooves 3.
Paracentesis needle holder 4 rear end faces one side is provided with a groove 6.
Sampling needle stand 5 front end faces one side is provided with a projection 7 that adapts with Paracentesis needle holder 4 rear end face upper grooves, 6 positions and shape.
