Detailed Description
The pretreatment device for paraffin embedding of organoid of the present utility model will be described in detail with reference to the accompanying drawings.
The pretreatment device for embedding organoid paraffin comprises: a handle member 10, a base member 20, an embedding cassette 30.
The handle member 10 comprises a base plate 11, a latch bar 12; the latch bar 12 is laterally formed at an upper side of the bottom plate 11; a plurality of slots 13 are formed in parallel on the lower side of the base plate 11. The slot 13 may be a dovetail groove or may be a suitable groove of other shapes.
The substrate member 20 includes a substrate body 21; a plug 23 is formed at the upper end of the substrate body 21; the shape of the plug 23 corresponds to the shape of the slot 13 of the base plate 11; the base member 20 is inserted into the insertion slot 13 of the handle member 10 by the plug 23; the substrate body 20 has a plurality of insertion holes 22 formed in an array.
Cassette 30 is used to house organoids; the embedding cassette 30 includes a cylindrical cassette body 31 and a cover body 32 detachably coupled thereto; the case 31 and the cover 32 are each formed with a plurality of through holes for allowing the reagents to enter the inside of the embedding case 30 therethrough; the cassette 30 is detachably mounted in the insertion hole 22 of the base plate member 20. Either a plug-in or a threaded connection. For example, a screw thread is formed on the outer periphery of the case 31; the insertion hole 22 is also formed with a screw thread on the inner circumference thereof, and the two are connected by the screw thread, so that the cassette 30 can be firmly mounted on the base plate body 21.
Both ends of the latch bar 12 extend outward beyond the width of the base plate member 20; the latch bar 12 is used to support the whole organoparaffin embedding pretreatment device on the upper edge of the reagent-containing cylinder.
When in use, firstly, the organoid which needs to be dehydrated pretreatment is placed in an embedding box; mounting the embedding cassette to a substrate; then mounting the substrate to the base plate through the plug; the substrate is inserted into a jar containing a dehydrated reagent, latch bars are supported on the edges of the jar, and the cassette is immersed in the reagent. After soaking for a predetermined period of time, the whole device is taken out by lifting the latch rod, and drained for the next operation.
