Row and between the width of the first straight line groove of equidistant arrangement, the center line of the two neighboring first straight line groove between
Away from, multiple be parallel to each other and the width of the second straight line groove of equidistant arrangement, the two neighboring second straight line groove
Between spacing, the minimum scale spacing of the long side scale coordinatometer and the minimum scale of short side scale coordinatometer between center line
Away from all same.
In said structure, the cutting blade that is chopped is connected by long side rod with long side pulley, and long when pulley is arranged on long
In groove and corresponding with long side scale coordinatometer, the displacement equivalent to chopped cutting blade in the long side direction of base can lead to
Long side scale coordinatometer understands in real time；Long cutting blade is connected by short side connecting rod with short side pulley, and short side pulley is installed
It is in short side groove and corresponding with short side scale coordinatometer, equivalent to long cutting blade the short side direction of base displacement
Can in real time it be understood by short side scale coordinatometer；So, user can control be chopped cutting blade and long cutting blade essence simultaneously
It is really mobile；Latticed groove on base is then conducive to coordinating with cutting blade and scale coordinatometer, further realizes accurate
Cutting.
Specifically, it is multiple to be parallel to each other and the width of the first straight line groove of equidistant arrangement, two neighboring described
Spacing between the center line of one straight-line groove, it is multiple be parallel to each other and the width of the second straight line groove of equidistant arrangement,
Spacing, the minimum scale spacing of the long side scale coordinatometer between the center line of the two neighboring second straight line groove and
The minimum scale spacing of short side scale coordinatometer is 1mm.
Preferably, the long side rod that can be stretched is by orthogonal many mutually nested connections of segment length's slide bar
Into；The short side connecting rod that can be stretched is formed by connecting by the short slide bar of orthogonal multistage is mutually nested.Here many segment lengths
Slide bar and the short slide bar of multistage, specific hop count determines as needed, can typically include four sections, i.e., the of the level being connected with pulley
One section, the vertical second segment being connected with the first paragraph other end, the 3rd section of level be connected with the second segment other end, with the 3rd
Vertical the 4th section of section other end connection, cutting blade is arranged on the 4th section of the other end；So, cutting blade can be in water
Square moved freely to vertical direction, realize actual displacement and push the function of cutting.
The beneficial effects of the utility model are：
Cutting blade is fixedly connected and corresponding with scale coordinatometer by the utility model with pulley by connecting rod, can be realized
The precise displacement and perpendicular cuts function of two orthogonal cutting blades, so that complete histology section is obtained, it is specific special
Point is as follows：
1st, brain tissue fixes preferable, and cutting angle is vertical, and cutting process mesencephalic tissue is indeformable, is readily obtained complete brain
Organize coronal and sagittal section；
2nd, according to brain tissue surface marker the brain area needed can be selected to carry out specific cutting；
3rd, double blade is cut simultaneously, it is ensured that obtain complete brain tissue section；
4th, cutting angle remains biological characteristic, easy to operate, compact conformation.
