Description
Technical field
The present invention relates to technical field of medical instruments, specifically a kind of biopsy needle.
Background technology
Biopsy needle is a kind of medicine equipment, it is adaptable to kidney, liver, lung, mammary gland, thyroid gland, prostate, pancreas, start ball,
A variety of organs such as uterus, ovary, body surface, available for cone tumour and the not clear living tissue sampling for planting tumour etc., draw cell.Face
On bed, when being checked for tumour patient, in order to determine the property of tumour, it is necessary to take some work groups from disease sites with biopsy needle
Knit.
Some existing biopsy needles are usually to be sampled by the way of tearing, and sample is irregular, it is difficult to get ideal
Living tissue, and complicated, cost is high.
The content of the invention
It is an object of the invention to provide a kind of biopsy needle, the biopsy needle easily can carry out cylinder to various living tissues
Body is sampled, and samples regular shape, and simple in construction, cost is low.
The technical solution adopted for the present invention to solve the technical problems is：
Biopsy needle, including needle tubing and nook closing member, nook closing member can coordinate with cannula slides；The head of the needle tubing is provided with cutting tooth, cuts
The zigzag of tooth in a ring is cut, the afterbody of needle tubing is provided with needle tube joint, needle tube joint provided with the connecting hole connected with needle tubing；Institute
The head for stating nook closing member is needle point, and afterbody is connected with grab handle；After nook closing member insertion needle tubing, needle point stretches out needle tubing head, needle tube joint
To grab handle formation block.
Further, the needle tube joint is in truncated cone, and the outer wall of needle tube joint can be connected with attractor formation matches somebody with somebody
Close, the connecting hole of needle tube joint can coordinate with the joint formation of syringe.
The beneficial effects of the invention are as follows：
First, nook closing member is engaged insertion human body with needle tubing, rotates needle tubing, and circular cutting is carried out to living tissue by cutting tooth, so that
The sample of cylinder is collected using needle tubing, regular shape is sampled；
2nd, for the living tissue of the suspension such as in bladder, by endoscope, it is connected using syringe or attractor with needle tube joint
Connect, so that sample is attracted in needle tubing, realize sampling；
3rd, on the one hand needle point can realize puncture, be on the other hand inserted into harder, the relatively sliding tissue in surface, realize to sampling
The positioning of position；
4th, this biopsy needle easy to use and flexible, simple in construction, cost is low.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the present invention；
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 nook closing member in Fig. 1.
Embodiment
As shown in figure 1, the present invention provides a kind of biopsy needle, including needle tubing 1 and nook closing member 2, nook closing member 2 can be slided with needle tubing 1
Coordinate；With reference to shown in Fig. 2 and Fig. 3, the head of needle tubing 1 is provided with cutting tooth 1a, the zigzags of cutting tooth 1a in a ring, needle tubing 1
Afterbody is provided with needle tube joint 3, needle tube joint 3 provided with the connecting hole 3a connected with needle tubing 1；As preferred, needle tube joint 3 is in
Truncated cone, the outer wall of needle tube joint 3 can be connected cooperation with attractor formation, and the connecting hole 3a of needle tube joint 3 can be with note
The joint formation of emitter coordinates；With reference to shown in Fig. 4, the head of nook closing member 2 is needle point 2a, and afterbody is connected with grab handle 4, grab handle 4
Cylinder and circular cone can be used using the shape for facilitating one hand to be affectedly bashful operation, such as cylinder, truncated cone etc., the present embodiment
The combined shaped of platform.
In use, nook closing member 2 is inserted into needle tubing 1 from needle tube joint 3, needle point 2a stretches out the head of needle tubing 1, and 3 pairs of needle tube joint is held
Hold the formation block of handle 4.
Then biopsy pin puncture is inserted into target sample position, extracts nook closing member 2 out, rotate needle tubing 1 while deep to tissue
Direction feeding needle tubing is spent, circular cutting is carried out to living tissue by cutting tooth 1a, so as to collect the sample of cylinder using needle tubing 1
This, samples regular shape.Living tissue for waiting suspension in bladder, by endoscope, using syringe or attractor and pin
Pipe joint 3 is connected, so that sample is attracted in needle tubing 1, realizes sampling；For harder, the relatively sliding tissue in surface, directly revolve
Rotating the needle pipe is not easy to screw in tissue, now first can not extract nook closing member 2 out, is positioned first with needle point 2a insertions sample position,
Rotating needle tubing again makes needle tubing screw in tissue slightly, extracts nook closing member 2 out afterwards and continues to rotate needle tubing completion sampling.
The above described is only a preferred embodiment of the present invention, not making any formal limitation to the present invention；Appoint
What those skilled in the art, without departing from the scope of the technical proposal of the invention, all using the side of the disclosure above
Method and technology contents make many possible variations and modification to technical solution of the present invention, or are revised as the equivalent reality of equivalent variations
Apply example.Therefore, every content without departing from technical solution of the present invention, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent substitution, equivalence changes and modification, still fall within technical solution of the present invention protection in the range of.
