2 center；The internal diameter of the sampling portion 2 everywhere is consistent, and outer diameter everywhere is also consistent, then samples more standard.
The pushing part 1 includes socket 10 and the piston rod 11 that can be slided up and down in the socket 10；The work
The bottom end of stopper rod 11 is set in the socket 10 and being capable of the sliding in the socket 10, preferably the bottom end setting of the piston rod 11
Flexible seal head 13 allows it to connect with the inner wall sealing of socket 10；The top of the piston rod 11 is equipped with positioned at described
Hand-held part 12 other than socket 10.
The one end in the sampling portion 2 is set to the top of the sample placement section 3, the other end in sampling portion 2 and the pipe
Cylinder connection with by the pushing of piston rod 11 by the release sampling of Electronic Speculum standard specimen 5 portion 2 of sampling portion 2 (i.e. the cavity 21 in).
The internal diameter in the sampling portion 2 is 0.8~1.2mm, and the outer diameter in the sampling portion 2 is 1~1.4mm, and sampling portion 2
Outer diameter is more than internal diameter.Preferably, the internal diameter in the sampling portion 2 is 1mm, and the outer diameter in the sampling portion 2 is 1.2mm, due to Electronic Speculum
Standard specimen 5 generally requires 1 cubic millimeter of particle, therefore, sets its internal diameter to 1mm and acquired sample size substantially can
Enough meet Electronic Speculum standard specimen；And the outer diameter in sampling portion 2 is unable to empress dowager, and empress dowager then takes standard specimen difficult, it is not easy to sample 30 is pierced through, and
But also sampling rate of precision substantially reduces, then can not be applied in Electronic Speculum.
The hand-held part 12 is set to the over top of socket, and the diameter of the hand-held part 12 is more than the internal diameter of socket；Institute
It states sampling portion 2 to be connect with the bottom end of the socket so that the cavity 21 is connected to the inside of the socket, then pushes or twitch
Ensure that air-flow is unobstructed when piston rod 11.Preferably, the hand-held part is equipped with the anti-skid bulge 14 for placing rubber sleeve, and
The anti-skid bulge 14 be preferably horizontal circle hand-held part periphery protrusion, the hand-held part 12 may be configured as central portion diameter it is small and
The big structure of top diameter, then the pull-out of piston rod 11 and pushing are more convenient.
The bottom face in the sampling portion 2 is a horizontal plane (i.e. close to one end of sample placement section 3), i.e., outer on bottom face
The thickness of wall everywhere is consistent with shape, then samples more accurate.
The fixed receiving portion 4 can be a tubular structure, and top is equipped with top end opening；Then sample 30 is directly placed
In on the top end opening and the top end opening being completely covered, facilitate sampling.
Embodiment 2
On the basis of embodiment 1, as also shown in e.g. figs. 4-7, the sample placement section 3 can have certain entity structure, tool
Body can be such as any one in following two, then sample 30 is placed more stable, and sampling is more convenient, and fault rate is also lower.
(1) as shown in figs. 4 and 6, the sample placement section 3 can be the support chip 31 that a center is equipped with opening, as support
Piece opening 310, support chip opening 310 are not more than the top end opening, and the support chip is positioned over the fixed receiving portion 4
Top, and the center that is Chong Die with the top end opening or being set to the top end opening that is open of the sample placement section 3 conveniently takes
Then sample 30 is positioned on the support chip by sample, and the opening of the support chip is completely covered in sample 30, then sampling portion
Need vertically to pierce down from the top of sample 30, and from the opening of support chip across.
(2) as shown in Fig. 5 and Fig. 7, the sample placement section 3 is the box body 32 being positioned on the top end opening, described
The upper surface and lower face of box body 32 are equipped with opening, as box opening 320, and 320 (i.e. upper end of upper and lower two box openings
The opening in face and the opening of lower face) coaxially, two box openings 320 of the box body 32 are no more than the top end opening.
The box body is positioned over the top of the fixed receiving portion 4, and the box opening 320 is Chong Die with the top end opening
Or be set to the center of the top end opening and facilitate sampling, sample 30 is then positioned over the tray interior, and sample 30 is set
It is placed between two box openings 320 of box body or more, then sampling portion only needs the opening from cassette upper end face to stretch into simultaneously vertical
Pierce down, pierce through sample 30 after again from the lower face of box body be open across, then push piston rod 11, will be in sampling portion cavity 21
Electronic Speculum standard specimen 5 release sampling portion, and fall to naturally in fixed receiving portion.
When specifically used, as shown in figs. 8-10, sample 30 is placed on the top end opening of fixation receiving portion of 2ml diameters,
Also sample 30 can be placed by 2 the method for embodiment, chooses materials position, sampling portion is inserted perpendicularly into simultaneously from the upper surface of sample
Sample is penetrated, the sample particle containing diameter about 1mm in the cavity in the portion of sampling at this time.It is last slowly to push piston tube, due to pipe
Air-flow in cylinder is compressed, and therefore, generates downward pressure or thrust makes the sample particle in sampling portion be pushed out and fall
In in fixed receiving portion, as Electronic Speculum standard specimen 5.
Certainly, according to different tests difference require, the internal organs of rat if necessary, then can conventional animal dissection, rapidly
The separation multiple internal organs of adult rat are immersed in 3% glutaraldehyde fixer (or 4% paraformaldehyde and 3% glutaraldehyde 1 respectively:1 mixing
Fixer), internal organs are then placed directly in the top of fixed receiving portion again or are positioned over the sample placement section described in embodiment 2
In 3, piston rod can be first pulled, draws 0.5ml fixers in socket, then fixer etc. is placed in fixed receiving portion, then
It is sampled again, sample particle is directly fallen in fixer after sampling.
The sample that can use different animals different tissues or internal organs according to above-mentioned application method, is then placed under Electronic Speculum
It is observed and recorded, certainly, routine operation must be carried out as needed before Electronic Speculum for big Multi-example, such as carry out ultra-thin cut
Piece, dyeing etc. processing.Certainly, the inventive point of these non-the utility model understands that this practicality is new just for the sake of facilitating
The use etc. of easy device described in type.
In the present invention, the replacements such as one piece of fixed plate can be used in the fixed receiving portion, such as can be on low temperature stencil plate
It is sampled.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, for this field
For technical staff, the utility model can have various modifications and changes.All institutes within the spirit and principle of the utility model
Any modification, equivalent substitution, improvement and etc. of work, should be included within the scope of protection of this utility model.
