Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
For technological means, creation characteristic, reached purpose and effect for making present invention realization are easy to understand, with reference to
Specific embodiment, is expanded on further the present invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of breast tissue puncture biopsy needle, including needle stand 10, after
The needle guard 20 that end is fixed on needle stand 10 is longer than needle guard 20, the work with the biopsy needle 30 being sheathed in needle guard 20, biopsy needle 30
Inspection pin 30 includes needle tubing 31 and the pull bar 32 that front end is located in needle tubing 31, rear end is stretched out in outside needle tubing 31, the pull bar 32 and pin
Pipe 31 keeps sealing, and pull bar 32 is longer than needle tubing 31, and the front end of needle tubing 31 is evenly equipped with a plurality of cutting edge 311 and is provided with many along its circumference
Individual to be located at the suction channel 312 connected between two adjacent cutting edges 311 and with needle tubing 31, the front end of needle tubing 31 is provided with recess, cuts
Sword 311 is cut at the recess, cutting edge 311 is strip, the length of suction channel 312 and the length of cutting edge 311
Roughly the same, preferably the bar number of cutting edge 311 is two, corresponding, and suction channel 312 is two, the preferably front end of needle tubing 31
End is cecum, and the front end of needle tubing 31 can be accommodated in needle guard 20, that is, pull needle tubing 31 that cutting edge 311 can be made to be accommodated in needle guard 20
It is interior, also including be arranged on needle stand 10 be used for drive needle tubing 31 rotate driving member 40 and for driving the driving member 40 to rotate
Drive device 50, the rear end of needle tubing 31 stretches out in that needle guard 20 is outer and through the driving member 40, and needle tubing 31 can exist along its axial direction
Slided on driving member 40, specifically, the pipe outer wall of the rear end of needle tubing 31 is provided with and the integrally formed drive block 313 of needle tubing 31, biography
It is provided with through its length direction and the chute 41 corresponding with drive block 313 in moving part 40, drive block 313 also functions to spacing
Effect, i.e., when the front end of drive block 313 abuts with the rear end face of needle guard 20, needle tubing 31 is no longer forward extended out.Driving member 40
Power passes to needle tubing 31 through drive block 313, and needle tubing 31 can also be slided along the length direction of chute 41, certain chute 41
Length direction is axially in parallel with needle tubing 31.
Operation principle：Before puncture, the front end of pull bar 32 is pushed into inside the front end of needle tubing 31, then pulls back needle tubing 31, made
In the storage of the front end of needle tubing 31 and needle guard 20.During puncture, first needle guard 20 is punctured into biological tissue, needle tubing is then released forward
31, then start drive device 50, drive driving member 40 to rotate, driving member 40 drives needle tubing 31 to rotate, the rotation process of needle tubing 31
In its front end biological tissue is cut, then pull back pull bar 32, because pull bar 32 and needle tubing 31 keep sealing, pull bar 32 to
Negative pressure is produced in moving process afterwards, so as to the biological tissue for cutting cutting edge 311 is sucked in needle tubing 31 through suction channel 312,
And then realize the extraction work of biological tissue.
To avoid pull bar 32 in the needle tubing 31 backward in moving process, pull bar 32 may drive needle tubing 31 in rotating to
Move by a small margin afterwards, preferably moving resistance of the pull bar 32 in needle tubing 31 is less than moving resistance of the needle tubing 31 in driving member 40.
A kind of puncture biopsy needle 30 of the present embodiment, the biological tissue needed for biopsy is extracted by only needing one-time puncture
Amount, had both alleviated the pain of patient, and the workload of doctor is reduced again.
Used as the further improvement of such scheme, the cross section of the pore of the needle tubing 31 is regular polygon, preferably positive six
Side shape, the pull bar 32 includes the guide section 321 positioned at its front end and the leading screw section 322 positioned at its rear end, the guide section 321
It is adapted with the pore shape of needle tubing 31, coordinated so as to form sealing with needle tubing 31, be i.e. the shape of guide section 321 and needle tubing 31
Pore shape is identical, in the same size, certainly to ensure sealing effectiveness, a groove can be opened in the side face of guide section 321, in the ditch
Groove is embedded in sealing ring, and a nut 60 coordinated with the leading screw 322 screw threads of section, the axis of nut 60 are connected with needle stand 10
With the axis collinear of needle tubing 31.When needle tubing 31 is driven in rotation, needle tubing 31 is matched somebody with somebody with the formation transmission of guide section 321 on pull bar 32
Close, so as to drive pull bar 32 to rotate, leading screw section 322 also forms transmission and coordinates with nut 60 in the rotation process of pull bar 32, due to spiral shell
Female 60 maintain static, therefore the moving axially backward along pull bar 32 of opposing nut 60 of pull bar 32, and finally, pull bar 32 is in needle tubing 31
It is moved rearwards by rotation process, in the biopsy suction needle tubing 31 that will be cut in moving process.By above-mentioned setting, pin is driven
Pipe 31 just completes the action of aspiration biopsy tissue while rotation, reduce the operating procedure of doctor, it also avoid more
Operating procedure to extract biopsy bring it is unfavorable, i.e., cause extra pain to patient.
Used as the further improvement of such scheme, 40 one-tenth tubuloses of the driving member, one end of driving member 40 is supported on pin
Seat 10 on and can around own axis, the drive device 50 be plane scroll spring, described plane scroll spring one end with
The other end of driving member 40 is connected, the other end and needle stand 10 are connected.During puncture, before releasing needle tubing 31 forward, first rotate manually and pass
Moving part 40, makes plane scroll spring gather elastic potential energy, then keeps driving member 40 motionless, needle tubing 31 is then released forward, so
Driving member 40 is unclamped afterwards, and in the presence of the elastic potential energy of plane scroll spring, driving member 40 drives needle tubing 31 to rotate, so that together
Step completes to cut and aspirate the action of biological tissue.
Used as the further improvement of such scheme, the other end of the driving member 40 is arranged with to be easy to rotate driving member 40
Regulation handle 70.
