Embodiment
As shown in figures 1-8, specimen sampling device of the present invention, includes the consistent He of inner sleeve 1 of length of gap suit
The two ends of outer tube 2, the two ends of inner sleeve 1 and the inwall of outer tube 2, which are connected, forms the toroidal cavity at middle part, passes through in toroidal cavity
The dividing plate 3 set along its length is partitioned into one group of symmetrical arcuate structure upper chamber 4 and arcuate structure lower chambers 5
（Referring to Fig. 6）, the chord length of upper chamber 4 and lower chambers 5 is consistent with the internal diameter of inner sleeve 1.
It is horizontally disposed with pull bar 6 on having along its length at the middle part of upper chamber 4, being horizontally disposed with the middle part of lower chambers 5 has
The lower push-pull bar 7 parallel with upper pull bar 6, upper pull bar 6 and lower push-pull bar 7 are moved axially back and forth along inner sleeve 1, upper push-and-pull
The rear end of bar 6 is connected by extension spring 8 and the rear end of inner sleeve 1, and its front end is fixed with and the width of upper chamber 4（The width of upper chamber 4 is its arc
Long length）Consistent flexible catch 9, because upper chamber 4 is consistent with the chord length of lower chambers 5, and be all on toroidal cavity one
Part, therefore the width of flexible catch 9 also can be consistent with the width of lower chambers 5；The front end of flexible catch 9, which extends forward, passes epicoele
Room 4, and extend downwardly and be threaded back through across after the front port of inner sleeve 1 to being connected with the front end of lower push-pull bar 7 in lower chambers 5（Upper pull bar 6
Connection with lower push-pull bar 7 is referring to Fig. 4）.
In flexible catch 9 cutting edge port 10, i.e. cutting edge port 10 are offered with the front port position corresponding position of inner sleeve 1
Diameter is consistent with the internal diameter of inner sleeve 1, and the length of flexible catch 9 positioned at the top of cutting edge port 10 is more than the diameter of cutting edge port 10
（Referring to Fig. 5）；Sliding block 11 is fixed with the rear end of lower push-pull bar 7, axially chute is offered along lower push-pull bar 7 in the bottom of outer tube 2
12, the rear end of chute 12 extends to form sliding block neck 13 to side, and the size of sliding block neck 13 is adapted with sliding block 11, and sliding block 11 is slided
It is dynamic to be arranged in chute 12.
Push rod 14 is equipped with inner sleeve 1, the front end of push rod 14 is installed with the taper passed from the cutting edge port 10
Termination 15, its rear end extends back inner sleeve 1, and the rear end of push rod 14 is installed with push pedal 16, and push pedal 16 is in the arc of cambered surface forward
Laminated structure, is conveniently pushed away, pulling-pushing rod 14（Referring to Fig. 3）；Offer and push away along its length on inner sleeve 1 and the side wall of outer tube 2
Groove 17 is drawn, the pushing block 18 slided along push-and-pull groove 17 is provided with the side wall of push rod 14, pushing block 18 extends outer tube 2, pushed away
The front end of groove 17 is drawn to extend to form pushing block neck 19 to side, the size of pushing block neck 19 is adapted with pushing block 18.
Indicate scale marker 20, the convenient depth judged in insertion sample along its length on the outer wall of outer tube 2；Outside
The rear end of sleeve pipe 2 is provided with the lever 21 of Surface coating anti-slip rubber layer, convenient to hold the insertion sample of lever 21.
Specimen sampling device operating process of the present invention is as follows：
First, hold lever 21 to insert specimen sampling device front end to position to be drawn materials top in sample, insertion depth is according to mark
Depending on this concrete condition, insertion depth can accurately be judged by scale marker 20 and whether inserted in place；When insertion in place
Pushing block 18 is released into pushing block neck 19 afterwards and push rod 14 is pulled back, pushing block 18 is moved to the rearmost end of push-and-pull groove 17, now
The front end of inner sleeve 1 is formed for containing the cavity of sample, then is inwardly inserted into specimen sampling device, is full of the front end cavity of inner sleeve 1
Sample（It is filled in the front end of sample top pressure push rod 14 in inner sleeve 1）, now for the insertion of specimen sampling device in place.
Then, sliding block 11 is quickly moved backward and is fastened in sliding block neck 13, and lower push-pull bar 7 is under the drive of sliding block 11
It is moved rearwards by, and drives the flexible catch 9 of front end connection to be moved into lower chambers 5, now the cutting edge port 10 in flexible catch 9
Sample can be cut off from top to bottom, while that section of flexible catch 9 positioned at the top of cutting edge port 10 can the front end of block inner sleeve 1
Mouthful, prevent the sample in inner sleeve 1 from dropping out,（Flexible catch 9 can move forward pull bar 6 during moving down,
Upper pull bar 6 pulls extension spring 8 again makes it trail）, now just can be taken off specimen sampling device.
Finally, treat that sliding block 11 is exited sliding block neck 13 by specimen sampling device after taking out, now in the return pulling force of extension spring 8
Under effect, upper pull bar 6 drives flexible catch 9 to retract in upper chamber 4, cutting edge port 10 is restored to and the front port of inner sleeve 1
Aligned position；Then push rod 14 is promoted forward, the sample in inner sleeve 1 is pushed out, just can be placed on long-term in cryopreservation tube
Freeze；Certainly a bit of sample can be also released, sliding block 11 is operated again, the sample outside inner sleeve 1 is cut, form piece
Shape, it is convenient directly to carry out pathologic finding.
