Description
Technical field
The present invention relates to biological tissue section machine, be specifically related to the cam mechanism of microtome.
Background technology
In mid-term in last century, along with people to the constantly understanding of disease and are studied, except being examined from big soma by naked eyes
Disconnected disease, also diagnoses the illness with greater need for from organizational structure and cellular change, and this is accomplished by making biological tissue the thin of about 5um
Sheet is examined under a microscope, thus creates the microtome of biological tissue, and biological tissue is arranged on embedding frame by paraffin, so
Rear embedding frame is arranged on embedding frame chuck, is cut into slices by blade.
Being the schematic diagram of existing microtome as shown in Figure 1, Mobile base 2 is slidably arranged on support 1, by handwheel or electronic
Mechanism can control Mobile base 2 and move back and forth along A direction on support 1, Mobile base 2 is provided with sample feeding mechanism and sample is solid
Determining mechanism, sample feeding mechanism includes that unilateral bearing 4, unilateral bearing 4 outer ring have lobe 5, and inner ring connects 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
Making the back-moving spring 3 that lobe 5 resets, microtome also includes being arranged on above lobe 5 for the feeding coordinated with lobe 5
Eccentric disc 6, concrete, when lobe 5 moves upward, the sidewall with feeding eccentric disc 6 is conflicted, because Mobile base 2 may proceed to upwards
Motion, so lobe 5 relative initial position can rotate, can control Mobile base 2 by the position of regulation feeding eccentric disc 6 every
Secondary move up rear lobe relative initial position rotate angle (lobe rotate time drive inner ring and and inner ring connect
Screw mandrel rotates together), i.e. can control the amount of feeding of each sample fixed mechanism, and when Mobile base 2 moves down (lobe 5
During away from feeding eccentric disc 6) because the effect of back-moving spring 3, lobe 5 rotates and resets, owing to being unilateral bearing, lobe 5
Screw mandrel can't be driven during reset to rotate, so, by the reciprocating motion of Mobile base 2, it is possible to make sample fixed mechanism gradually move
The dynamic blades fit with microtome, carries out sectioning.
But the microtome of Fig. 1 is operationally, rear sample fixed mechanism of having imposed uniformity without examining individual cases can not bounce back, and fixes machine at sample
During structure moves upward with Mobile base 2, blade can contact with sample, glutinous cutter phenomenon easily occurs, not only breaks up sample, also
It is easily reduced the service life of blade.
Summary of the invention
The present invention is directed to the problems referred to above, overcome at least one not enough, it is proposed that the cam mechanism of a kind of microtome.
The technical scheme that the present invention takes is as follows:
The cam mechanism of a kind of microtome, described microtome includes support, the Mobile base being slidably arranged on support, described
Being provided with sample feeding mechanism on Mobile base, sample feeding mechanism includes unilateral bearing, and the inner ring of unilateral bearing connects screw mandrel, described movement
Seat includes installing plate, and installing plate has the through hole passed for screw mandrel, and described screw mandrel has spacing ring, described unilateral bearing and limit
Position ring lays respectively at the both sides of described through hole, and described cam mechanism includes:
