Circular cone casing constitutes external electrode, and inside and outside two electrodes can be connected on external puncture indicator by the socket on handle.
Using the puncture needle, safe operation is reliable, punctures high-efficient.
China's patent No. 201310365648.4 discloses another Medical myeloid puncture needle, including needle body, and feature exists
In handle is arranged in setting needle core in the needle body, needle body middle part, and the cinclides of at least one is arranged in needle body front end, and sawtooth is arranged
Knife, the needle core stretch out 3-6mm from needle body front end, and the needle point of the needle core is polygonal pyramid shape.It is more convenient for using when operation of the present invention
Power is improved the success rate of working efficiency and puncture, mitigates the pain of patient, and can also not only be taken out with bone marrow extraction liquid
Living tissue is taken to do biopsy, multiple cinclides on needle body can be conducive to the detection of lesion in different location marrow aspiration.
However, above two medical myeloid biopsy needle is controlled by doctor oneself
Rotation and puncture dynamics, it is more likely that it is excessive dynamics occur, when causing to puncture marrow, the structure of marrow is compromised, to later disease
The growth of the bone of people causes to damage.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of medical myeloid biopsy needle
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of medical myeloid biopsy needle, including needle
The top of core, lower body of rod, upper body of rod, helical spring, annular baffle and ball, the needle core is equipped with push top, the lower body of rod
One end be equipped with zigzag structure, a needle core is equipped with inside the lower body of rod, the other end of the lower body of rod is arranged on described
The inside of the body of rod, the center inside the upper body of rod are equipped with an annular baffle, the annular baffle and the lower beam
It is equipped with ball between the top of body, helical spring is equipped between the annular baffle and upper body of rod.
Preferably, the lower upper body of rod is that the needle core is connected by bearing with annular baffle.
Preferably, the lower body of rod is connected in the position of the upper body of rod bottom by bearing with upper body of rod.
Preferably, the surface of the upper body of rod is equipped with anti-skid bulge.
Preferably, the ball includes at least 8 groups, and the ball is uniformly set at the top of the lower body of rod and annulus
At the 3/4R of the lower surface of shape baffle, and at the top of the lower body of rod and lower surface of annular baffle be equipped with it is described for placing
The semi-circular recesses of ball.
Compared with prior art, the beneficial effects of the present invention are: by helical spring provide support degree, to control
Dynamics when puncture reduces injury of the zigzag structure for marrow, mitigates the pain of patient and makes the marrow rehabilitation of patient
Accelerate.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
In figure: 1, needle core, 2, lower body of rod, 3, bearing, 4, upper body of rod, 5, anti-skid bulge, 6, push top, 7, helical spring, 8,
Annular baffle, 9, ball.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of medical myeloid biopsy needle, including needle core 1, under
The top of the body of rod 2, upper body of rod 4, helical spring 7, annular baffle 8 and ball 9, the needle core 1 is equipped with push top 6, the lower beam
One end of body 2 is equipped with zigzag structure, and a needle core 1 is equipped with inside the lower body of rod 2, and the other end setting of the lower body of rod 2 exists
The inside of the upper body of rod 4, the center inside the upper body of rod 4 are equipped with an annular baffle 8, the annular baffle 8
It is equipped with ball 9 between the top of the lower body of rod 2, helical spring 7 is equipped between the annular baffle 8 and upper body of rod 4.
The upper body of rod 4 is that the needle core 1 is connected by bearing 3 with annular baffle 8；The lower body of rod 2 and upper boom
