Description
Technical field
The utility model is related to biological tissue section machine and in particular to the cam mechanism of slicer.
Background technology
In last century mid-term, with people to the continuous understanding of disease and research, except being examined from substantially tissue by naked eyes
Disconnected disease, also diagnoses the illness with greater need for from institutional framework and cellular change, this be accomplished by by biological tissue make 5um about thin
Piece is examined under a microscope, thus creates the slicer of biological tissue, and biological tissue is arranged on embedding frame by paraffin, so
Embedding frame is arranged on embedding frame chuck afterwards, is cut into slices by blade.
It is the schematic diagram of existing slicer as shown in Figure 1, Mobile base 2 is slidably arranged on support 1, by handwheel or electronic
Mechanism can control Mobile base 2 to move back and forth along along A direction on support 1, Mobile base 2 is provided with sample feeding mechanism and sample is solid
Determine mechanism, sample feeding mechanism includes unilateral bearing 4, unilateral bearing 4 outer ring has lug boss 5, and inner ring is connected with screw mandrel, screw mandrel and sample
Product fixed mechanism coordinate, sample fixed mechanism can be driven to move along B direction when screw mandrel rotates, sample feeding mechanism also include for
Make the back-moving spring 3 that lug boss 5 resets, slicer also includes being arranged on lug boss 5 top for the feeding with lug boss 5 cooperation
Eccentric disc 6, specifically, is conflicted with the side wall of feeding eccentric disc 6 when lug boss 5 moves upwards, because Mobile base 2 may proceed to upwards
Motion, so lug boss 5 relative initial position can rotate, can control Mobile base 2 every by adjusting the position of feeding eccentric disc 6
Secondary move up angle that rear lug boss relative initial position rotates and (drive inner ring when lug boss rotates and connect with inner ring
Screw mandrel rotates together), can control the amount of feeding of each sample fixed mechanism, and work as Mobile base 2 and move down (lug boss 5
During away from feeding eccentric disc 6) because the effect of back-moving spring 3, lug boss 5 rotates and resets, due to being unilateral bearing, lug boss 5
Screw mandrel can't be driven during reset to rotate, so, by the reciprocating motion of Mobile base 2, sample fixed mechanism can be made gradually to move
The dynamic blades fit with slicer, carries out sectioning.
But the slicer of Fig. 1 is operationally, rear sample fixed mechanism of having imposed uniformity without examining individual cases can not bounce back, and fixes machine in sample
During structure moves upwards with Mobile base 2, blade can be contacted with sample, glutinous knife phenomenon easily, not only break up sample,
It is easily reduced the service life of blade.
