Description
Technical field
The utility model is related to the field of medical instrument technology more particularly to a kind of cytology biopsy needles.
Background technology
It is presently used for puncturing the histoorgans such as patient's soft tissue, lymph node, thyroid gland, stings and take tissue block, carry out live body group
The puncture needle for the Tissue pathological diagnosis knitted is common, and to mitigating patient's pain, accurate quickly progress cyto-diagnosis has it
Certain sense, but due to some design defect, have the following disadvantages：It is that tack or inclination are set at the top of the needle tubing of existing puncture needle
Set, sting the when of taking tissue be easy to cause needle tubing is mobile, skid situations such as occur, seriously affect sampling or even damage patient's group
The serious consequence knitted.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of stability, and one kind that is more preferable, being more easy to grasping tissue is thin
Born of the same parents learn biopsy needle.
The technical solution that the utility model solves above-mentioned technical problem is as follows：A kind of cytology biopsy needle, including even
Socket part, limit spring, syringe and needle core, the interconnecting piece are pipe structure, and lug boss, institute are equipped with around the middle part of the interconnecting piece
Pinch-take tablet there are two being set on lug boss is stated, the both ends of the lug boss are the plane vertical with tube axial direction, the end of the syringe
End is fixed on the inside of the interconnecting piece, and the front end of the syringe is zigzag, and the needle core removably passes through the connection
Portion is arranged in the syringe, and the front end of the needle core is taper, and the rear end of the needle core is equipped with lid, and the needle core is fully inserted into
When the syringe, the rear plane contact of the lid and the lug boss, the rear end of the interconnecting piece is set in the lid, described
Limit spring is removably set on the syringe.
The utility model has the beneficial effects that：The purity for avoiding non-targeted sampling, improving sampling, syringe front end are equipped with saw
Tooth form, is both easy sampling, while while sampling is not easy to skid, improves stability when sampling.
Further, when the needle core is fully inserted into the syringe, the tapered front end of the needle core is exposed at outside the syringe.
Using the advantageous effect for the scheme that is further improved：The tapered front end of needle core is exposed at outside the syringe, convenient for being pierced into
Tissue, and ensure before determining target, it keeps in syringe being closed environment, avoids non-targeted extraction, and then improve and take
Sample purity.
Further, two pinch-take tablets are oppositely arranged, and each pinch-take tablet is outwardly extending arcuate structure.
Using the advantageous effect for the scheme that is further improved：The pinch-take tablet for the arcuate structure being oppositely arranged takes puncture convenient for pinching
Needle.
Further, the outer surface of each pinch-take tablet is equipped with a plurality of anti-slip tank.
Using the advantageous effect for the scheme that is further improved：Prevent from pinching puncture muff caused by rubber sleeve when taking puncture needle.
Further, the limit spring is an one metal wire, the middle part of the wire around a circle and both ends respectively to
Interior bending is to form grip part.
Using the advantageous effect for the scheme that is further improved：The metal wire structure is simple, by being simply bent to form with one
Determine the grip part of elastic force.
Further, further include pipe sleeve, the pipe sleeve is removably arranged the syringe, and with the frontal plane of the lug boss
Contact.
Using the advantageous effect for the scheme that is further improved：Prevent needle tubing from puncturing packaging bag.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of cytology biopsy needle of the utility model.
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of cytology biopsy needle includes interconnecting piece 1, limit spring 2, syringe 3 and needle core 4, even
Socket part 1 is pipe structure, and the middle part of interconnecting piece 1 is equipped with lug boss 5, is set on lug boss 5 there are two pinch-take tablet 51, the two of lug boss 5
End is equipped with the plane vertical with the tube axial direction of interconnecting piece 1, and the end of syringe 3 is fixed on the inside of interconnecting piece 1, before syringe 3
End is zigzag, and 3 front end of syringe is equipped with zigzag, is both easy sampling, while while sampling is not easy to skid, improves stabilization when sampling
Property.Needle core 4 removably passes through interconnecting piece 1 to be arranged in syringe 3, and the front end of needle core 4 is taper, and the rear end of needle core 4 is equipped with lid
6, when needle core 4 is fully inserted into syringe 3, the rear plane contact of lid 6 and lug boss 5, while the rear end of interconnecting piece 1 is set in lid 6,
Limit spring 2 is removably set on syringe 3.
When needle core 4 is fully inserted into syringe 3, the tapered front end of needle core 4 is in the outside of syringe 3.The tapered front end of needle core 4 is revealed
Outside syringe 3, convenient for being pierced into tissue, and ensure before determining target, keeps in syringe 3 being closed environment, avoid non-
Objective extraction, and then improve sampling purity.
Two pinch-take tablets 51 are oppositely arranged, and each pinch-take tablet 51 is outwardly extending arcuate structure.The arc being oppositely arranged
The pinch-take tablet 51 of shape structure, puncture needle is taken convenient for pinching.
The outer surface of each pinch-take tablet 51 is equipped with a plurality of anti-slip tank.It prevents from pinching puncturing caused by rubber sleeve when taking puncture needle and lose
Accidentally.
Limit spring 2 is an one metal wire, and the middle part of wire is enclosed around one and both ends are respectively bent inward and are held with being formed
