Description
Technical field
The utility model is related to the field of medical instrument technology, specifically a kind of biopsy needle.
Background technology
Biopsy needle is a kind of medical instrument, suitable for kidney, liver, lung, mammary gland, thyroid gland, prostate, pancreas, start ball,
A variety of organs such as uterus, ovary, body surface can be used for the living tissue sampling of cone tumour and unknown kind of tumour etc., draw cell.Face
On bed, when checking for tumour patient, in order to determine the property of tumour, need to take some work groups from disease sites with biopsy needle
It knits.
Some existing biopsy needles are usually used the mode torn and are sampled, and sample is irregular, it is difficult to get ideal
Living tissue, and it is complicated, it is of high cost.
Utility model content
The purpose of this utility model is to provide a kind of biopsy needle, which can easily carry out various living tissues
Cylinder samples, and samples regular shape, and simple in structure, at low cost.
Technical solution adopted by the utility model to solve its technical problems is：
Biopsy needle, including needle tubing and needle core, needle core can coordinate with cannula slides；The head of the needle tubing is equipped with cutting
The tail portion of tooth, the zigzag of cutting tooth in a ring, needle tubing is equipped with needle tube joint, and the connection being connected to needle tubing is equipped in needle tube joint
Hole；The head of the needle core is needle point, and tail portion is connected with grab handle；After needle core is inserted into needle tubing, needle point stretches out needle tubing head, needle tubing
Connector forms block to grab handle.
Further, the needle tube joint is in truncated cone, and the outer wall of needle tube joint can form connection with attractor and match
It closes, the connecting hole of needle tube joint can be formed with the connector of syringe to be coordinated.
The utility model has the beneficial effects that：
One, needle core matches insertion human body with needle tubing, rotates needle tubing, and round cutting is carried out to living tissue by cutting tooth,
To collect cylindrical sample using needle tubing, regular shape is sampled；
Two, for the living tissue of the suspensions such as in bladder, by endoscope, using syringe or attractor and needle tube joint
It is connected, to which sample to be attracted in needle tubing, realizes sampling；
Three, on the one hand needle point can realize puncture, on the other hand be inserted into the tissue that surface is harder, relatively sliding, realization pair
The positioning of sample position；
Four, this biopsy needle easy to use and flexible, it is simple in structure, at low cost.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of needle tubing in Fig. 1；
Fig. 3 is the enlarged diagram of cutting tooth in Fig. 2；
Fig. 4 is the schematic diagram of needle core in Fig. 1.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of biopsy needle, including needle tubing 1 and needle core 2, needle core 2 can be with needle tubing 1
It is slidably matched；As shown in figure 3 in conjunction with Fig. 2, the head of needle tubing 1 is equipped with cutting tooth 1a, the zigzags of cutting tooth 1a in a ring, needle tubing
1 tail portion is equipped with needle tube joint 3, and the connecting hole 3a being connected to needle tubing 1 is equipped in needle tube joint 3；Preferably, needle tube joint
3 be in truncated cone, and the outer wall of needle tube joint 3 can form connection cooperation with attractor, and the connecting hole 3a of needle tube joint 3 can be with
The connector of syringe forms cooperation；In conjunction with shown in Fig. 4, the head of needle core 2 is needle point 2a, and tail portion is connected with grab handle 4, grab handle
4 may be used the shape for facilitating one hand to be affectedly bashful operation, such as cylindrical, truncated cone etc., and the present embodiment uses cylinder and circle
The combined shaped of frustum.
In use, needle core 2 is inserted into needle tubing 1 from needle tube joint 3, needle point 2a stretches out 1 head of needle tubing, and needle tube joint 3 is to holding
It holds handle 4 and forms block.
Then biopsy pin puncture is inserted into target sample position, extracts needle core 2 out, to tissue depth on one side rotate needle tubing 1 while
It spends direction and is sent into needle tubing, round cutting is carried out to living tissue by cutting tooth 1a, to collect cylindrical sample using needle tubing 1
This, samples regular shape.For the living tissue of equal suspensions in bladder, by endoscope, using syringe or attractor and needle
Pipe fitting 3 is connected, and to which sample to be attracted in needle tubing 1, realizes sampling；Tissue harder for surface, relatively sliding directly revolves
Rotating the needle pipe is not easy to screw in tissue, can not extract needle core 2 out first at this time, and being inserted into sample position first with needle point 2a is positioned,
Rotating needle tubing again makes needle tubing screw in tissue slightly, extracts needle core 2 out later and continues to rotate needle tubing completion sampling.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Any technical person familiar with the field, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment, still fall within this practicality
In the range of the protection of new technique scheme.
