Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of pathologic section slicer moves back blade mechanisms.
Background technique
Pathologic section slicer is the key equipment for preparing pathological section, and in pathologic section slicer use process, blade is mounted in knife
It in the gap of bar and hold(ing)-down clip, is fixed by hold(ing)-down clip, when more allowing blade replacement, hold(ing)-down clip need to be unclamped, with other thin slice
It after one segment length of end face that blade is released to blade bearing and push type broach sheet separation, is taken out with hand, operates not only dangerous but also cumbersome, work
Low efficiency.Therefore people devise withdrawing device, push blade with one on withdrawing device telescopic pin shaft, although working efficiency has
Improve but there are still following disadvantages: pathological tissue specimen moves up and down relative to blade, and the histotomy cut often crimps
At the cutting edge of hold(ing)-down clip and blade, is still crimped when removing, influence subsequent use.
And withdrawing device is when being in withdrawing position, withdrawing device lower edge and hold(ing)-down clip have certain gap, and the tissue cut is cut
When piece passes through the gap, curved histotomy can be smoothed out with the fingers flat, and the withdrawing device of the prior art, rotation axis is located on hold(ing)-down clip,
Rotation axis and axis hole gap are smaller, therefore the gap of withdrawing device lower edge and hold(ing)-down clip cannot be adjusted, or adjustment amplitude very little, no
It is able to satisfy the requirement of different-thickness histotomy.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of pathologic section slicer and move back blade mechanisms, make
It can be adjusted according to the requirement of different-thickness histotomy at the top of withdrawing plate rack with push type broach sheet separation, and its structure is simple, behaviour
Facilitate, work efficiency is high.
Above-mentioned goal of the invention is achieved through the following technical solutions: a kind of pathologic section slicer moves back blade mechanisms, it is wrapped
Blade bearing, hold(ing)-down clip are included, withdrawing plate rack is characterized by, and is equipped on blade bearing and is moved back blade mechanisms, described moves back rolling reamer machine
Structure is each to fix on axis a B, every axis B that move cooperation rotatable equipped with lever connecting plate two sides of blade bearing are symmetrical；Every piece of thick stick
Bar connecting plate galianconism one end is equipped with gap adjusting hole, and the two sides of blade bearing correspond to gap adjusting hole and are equipped with screw hole, matches rotation in screw hole
Have the adjustment bolt of lever connecting plate and the adjustable connection of blade bearing across gap adjusting hole, the diameter of gap adjusting hole is greater than
The diameter of adjustment bolt screw thread, less than the diameter on adjustment bolt head；An axis A is fixed in every piece of long-armed one end of lever connecting plate, at
The dynamic cooperation of the withdrawing plate rack of gantry shape is rotatable to be mounted on two axis A；Wherein side is equipped with one at the top of the withdrawing plate rack
Move back blade assembly.
Preferably, it is described move back blade assembly include withdrawing piece push rod, the push rod telescopic hole ontology on withdrawing plate rack,
Reset spring, withdrawing piece hand press bar, and push rod telescopic hole ontology one end is push rod telescopic hole, and the other end is communicated with push rod telescopic hole
Diameter is less than the through-hole of push rod telescopic hole, and withdrawing piece push rod system is multi-diameter shaft, and it is straight that the head diameter of withdrawing piece push rod is greater than through-hole
Diameter, withdrawing piece putter shaft is scalable in push rod telescopic hole across through-hole, and withdrawing piece push rod tail portion and withdrawing piece hand press bar
It is fixedly connected, withdrawing piece hand presses bar and the dynamic cooperation of push rod telescopic hole, resets bullet and is centered around withdrawing piece push rod in push rod telescopic hole
On shaft, reset bullet one end is pressed bar with withdrawing piece hand and is fixedly connected, and other end is fixedly connected with through-hole wall.
This practical operation sequence is as follows: the adjustment bolt in the two sides screw hole of blade bearing is unclamped, according to pathological section
It is required that the thickness cut, rocking lever connecting plate, rotate the gap adjusting hole (18) on lever connecting plate around adjustment bolt,
So that the gap of withdrawing plate rack and hold(ing)-down clip on two axis A of rocking lever connecting plate is reached requirement, then screws knife again
Withdrawing plate rack is accurately positioned in adjustment bolt in the two sides screw hole of bar.It is only to need pressing withdrawing when exiting blade
Piece hand presses bar, and blade is i.e. mobile to expose hold(ing)-down clip, and operator can safely and fast remove blade.
The utility model has the advantages that compared with prior art: one, can when operator adjusts tissue specimen
So that withdrawing plate rack is in withdrawing position, prevents the hand and blade contact of operator, improve and make safety；Two, it realizes fast
Fast withdrawing, it is easy to operate, it improves work efficiency；Three, making can be according to different-thickness with push type broach sheet separation at the top of withdrawing plate rack
The requirement of histotomy adjusts.And clever structure, it is easy to operate, it is provided again for the update to existing pathologic section slicer
The technical solution of one part.
