Abstract
The utility model discloses a kind of freezing tissue block cutter sweep, mainly comprise cutter, handle of a knife, stressed pad and splash guard, described handle of a knife is cone, cutter are fixed on the bottom of handle of a knife, cutter comprise four identical blades, four blades are uniformly distributed along the bottom surface of handle of a knife, the intersect ends of four blades and being welded and fixed, described stressed pad is positioned at the top of handle of a knife, described splash guard is hollow cylinder, described cutter are made up of stainless steel substrates, and the thickness of every sheet blade is 0.6mm, and described stressed pad is rubber blanket.Described splash guard is made up of transparent low temperature resistant glass.Tissue block to be cut is covered by splash guard by the utility model, the related cutter of handle of a knife enter from the upper shed of splash guard and cut tissue block, effectively avoid outside liquid nitrogen and broken tissue block and spatter, reduce tissue block loss, prevent laboratory technician from being spattered liquid nitrogen lesions outward simultaneously.
Description
Technical field
The utility model relates to experiment equipment field, is specifically related to a kind of freezing tissue block cutter sweep.
Background technology
At present, the original preservation of biological organization material all needs liquid nitrogen frozen to preserve, to avoid the degraded causing nucleic acid and protein.Frozen tissue block is often comparatively large, or mutually freezes together, and going to toward needing to split tissue block carrying out experiment, saving sample first, second saving the reagent used in follow-up test and consumptive material, and reducing workload, increasing work efficiency.But, when splitting tissue block for ensureing that cryopreserved tissue can not melt, generally tissue block being immersed in liquid nitrogen and splitting.The method of segmentation is all directly broken into pieces by tissue block with grinding pestle or other apparatus usually.Such operation often causes broken tissue block to splash away from liquid nitrogen and spatters outside liquid nitrogen, causes tissue block loss, the even outer consequence of spattering liquid nitrogen and hurting sb.'s feelings.Therefore, supercool freezes tissue block segmentation problem is urgently to be resolved hurrily safely and efficiently.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of freezing tissue block cutter sweep, and this cutter sweep can be avoided spattering outside liquid nitrogen and broken tissue block, avoids tissue block to lose and spatter liquid nitrogen outward and hurts sb.'s feelings.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of freezing tissue block cutter sweep, mainly comprise cutter, handle of a knife, stressed pad and splash guard, described handle of a knife is cone, cutter are fixed on the bottom of handle of a knife, cutter comprise four identical blades, and four blades are uniformly distributed along the bottom surface of handle of a knife, the intersect ends of four blades and being welded and fixed, described stressed pad is positioned at the top of handle of a knife, and described splash guard is hollow cylinder.
Further, described cutter are made up of stainless steel substrates, and the thickness of every sheet blade is 0.6mm.
Further, described stressed pad is rubber blanket.
Further, described splash guard is made up of low temperature resistant clear glass, as tempering quartz glass, high-boron-silicon glass etc., the height of splash guard be cutter and handle of a knife overall height and 2/1 to three/2nds between.
A kind of freezing tissue block of the utility model cutter sweep, tissue block to be cut is covered by splash guard by this cutter sweep in use, the related cutter of handle of a knife enter from the upper shed of splash guard and cut tissue block, effectively avoid outside liquid nitrogen and broken tissue block and spatter, reduce tissue block loss, prevent laboratory technician from being spattered liquid nitrogen lesions outward simultaneously.
Accompanying drawing explanation
According to drawings and embodiments the utility model is described in further detail below.
Fig. 1 is the structural representation of a kind of freezing tissue block of the utility model cutter sweep.
In figure: 1-blade; 2-handle of a knife; The stressed pad of 3-; 4-splash guard.
Embodiment
As shown in Figure 1, a kind of freezing tissue block cutter sweep described in the utility model embodiment, mainly comprises cutter, handle of a knife 2, stressed pad 3 and splash guard 4, and handle of a knife 2 is in cone, cutter are fixed on the bottom of handle of a knife 2, cutter comprise four identical blade 1, four blades 1 and are uniformly distributed along the bottom surface of handle of a knife 2, the intersect ends of four blades 1 and being welded and fixed, stressed pad 3 is positioned at the top of handle of a knife 2, splash guard 4 is hollow cylinder, splash guard 4 internal diameter 2.5cm, wall thickness 0.3mm.
One preferred embodiment, cutter are made up of stainless steel substrates, the thickness of every sheet blade 1 is 0.6mm, stressed pad 3 is rubber blanket, when cutting tissue block, stressed pad 3 can be knocked by force application means such as hammers, being more convenient for cutting tissue block, stressed pad 3, to having knocked buffer action, effectively can avoid the splashing of tissue block and liquid nitrogen.
More preferred, splash guard 4 is made up of low temperature resistant clear glass, as tempering quartz glass, high-boron-silicon glass etc., the height of splash guard 4 be cutter and handle of a knife 2 overall height and 2/1 to three/2nds between, be convenient to the cutting situation of observing its inside.
A kind of freezing tissue block of the utility model cutter sweep, in use, first by splashproof cloche precooling a period of time under ultra-low temperature surroundings (as-80 DEG C of refrigerators), then appropriate liquid nitrogen is contained in low temperature resistant mortar, taking out tissue block is dipped in liquid nitrogen, tissue block covers by rapid splash guard, is then entered from splash guard upper shed by cutter, and observes through splash guard, cutter are made to be pressed in tissue block central authorities, now, handle of a knife can be held firmly down, with incised tissue block.If the strength of hand is inadequate, the instruments such as hammer can be used, appropriateness knocks stressed pad, because stressed pad is elastomeric material, has certain buffer action to impact, have certain effect to avoiding the splashing of tissue block and liquid nitrogen, after having cut, take off cutter and splash guard, as required the selections such as packing are carried out to the tissue block after cutting, implement in whole process, operating personnel need wear Frostbite preventing gloves.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; for a person skilled in the art; it still can regulate the technical scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
