A kind of histotomy row knife system

Technical field

The utility model relates to a kind of medical research device, especially a kind of technical field that is used for the medical tissue slice device.

Background technology

In medical research, usually need calculate the volume of blocking tissue.The volume of blocking tissue has great significance to research curative effect of medication, its related pathologies physiological mechanism and disease animal model evaluation in correlative study; The volume that how to calculate blocking tissue quickly and accurately is the problem that the association area researchist inquires into always.

At present; The comparatively general blocking tissue's calculation method of physical volume in this field is: fix fast after earlier sample tissue being placed-20 ℃ of freezing 20min; Be cut into the section of fixed thickness again; Make blocking tissue and normal tissues present various colors through dyeing and other processing,, use the volume that related software calculates blocking tissue through image capture devices such as digital camera, scanner input computing machine; The technical requirement of this method is: the one, and owing to blocking tissue is prone to liquefaction, is prone to from normal tissues, come off, therefore cut into slices and want rapidly, fixing fast behind-20 ℃ of freezing 20min, prevent to organize stripped back form and structure to change; The 2nd, it is consistent that slice thickness is wanted, and could guarantee that late time data obtains blocking tissue's volume accurately when handling; The 3rd, the desirable precise thickness of a slice to the end when last a slice can not be with former consistency of thickness.

In the prior art owing to there is not special-purpose slicing device; The experimenter uses the free-hand section of blade range estimation thickness more in operation; Or the self-made tool of use razor blade and the range upon range of combination of microslide; Because razor blade is the Elastic Steel material, the tissue variable thickness that deformation causes cutting out possibly take place in slicing processes cause, thereby influence the accuracy and the reliability of experiment; Therefore need badly and improve existing tissue slice apparatus, particularly needing badly provides a kind of tissue consistency of thickness of in slicing processes, guaranteeing, can tissue be organized the device of accurate section fast.

Summary of the invention

The utility model is to there not being special-purpose histotomy apparatus in the prior art; The tissue variable thickness that causes cutting out because of deformation in the ubiquity slicing processes causes; Can not tissue be organized the state of the art of accurate section fast; The utility model purpose is to provide a kind of histotomy row knife system, and this device has simple structure, easy operating, can realize carrying out quickly and accurately the equipment of histotomy.

The utility model solves its technical matters and takes following technical scheme to realize:

The utility model is through having designed a kind of histotomy row knife system; The characteristics of this histotomy row cutter have been to combine the fixedly advantage of row's cutter and vernier caliper; Can select the different row's knife assembly of blade number according to the histoorgan size of slice; Spacing is identical between row's cutter blade, thereby guarantees to cut out the section of uniform in thickness, and the thickness of last a slice can be measured clamp by the back and accurately record according to the scale on the blade.

The utility model specifically provides a kind of histotomy row knife system; This device is made up of blade, blade, shifting board, fastening adjustment device and the draw-in groove of handle of a knife, combination gang feed tool rack, fastener, fixed dam, band vernier graduation, and handle of a knife is formed the clamp that has the double-pole handle with the blade of band vernier graduation; Fixed dam and shifting board vertical sleeve are on clamp, and wherein, fixed dam is enclosed within on the clamp through vertical fixing, and shifting board is enclosed within on the clamp through the fastening adjustment device; The combination gang feed tool rack is made up of draw-in groove, blade and fastener; Wherein, The draw-in groove bottom surface is connected with the blade vertical fixing, and the blade trend is parallel with shifting board, is provided with the clamp that has the double-pole handle is vertical; Be equidistant setting between the blade, knife number is provided with the varying number blade according to the big or small needs of biopsy tissues; Draw-in groove is " recessed " font, will fix to clamp in the groove of draw-in groove with the blade of vernier graduation through fastener.

The histotomy row knife system that provides according to above-mentioned utility model has following characteristics:

1, the detachable structure of histotomy row knife system that provides of the utility model according to the difference of slice histoorgan size, is selected corresponding row's knife assembly, and is practical, applied range.

2, the histotomy row knife system that provides of the utility model adopts the design of row's cutter, easy and simple to handle rapidly, reduce exsomatize back form and structure of tissue and change.

3, the histotomy row knife system that provides of the utility model utilizes vernier caliper principle, accurately measures slice thickness, and it is more accurate that focus or Infarction volume are calculated, and experimental result is more reliable.
