Abstract

The utility model relates to a slicer, composed of a body case, a hand wheel, a machine frame, a slicing knife carriage, a microtome knife, a feed rod, a pendulum bar, a connecting rod, a specimen holder, a screw rod, a hinge and a refrigeration system composed of a compressor and a condenser. The hand wheel is connected with the pendulum bar provided with a specimen by the connecting rod. The utility model is characterized in that a stepping motor is connected with the feed rod by the screw rod. The stepping motor can also control the horizontal feed of the pendulum bar. Owing to the adoption that the stepping motor is connected with the feed rod by the screw rod and it can also control the horizontal feed of the pendulum bar, the utility model is omitted a driving device, an amount of feed preselectingmechanism, a specimen return-stroke yielding and a pawl return-stroke yielding. The device has the advantages of simple structure, accurate motion and stability.

Description

Microtome

Technical field

The utility model relates to the Medical Devices technical field, particularly a kind of microtome that is used for histopathologic analysis.

Background technology

Freezing microtome section is the main means of histopathologic analysis, the thickness of the section of overview diagnosis is 5-7 μ m, present freezing-microtome mainly is made up of refrigeration, control and section movement four parts, pass through turning handle, feed rod is that rotate at the center and the propelling of sample level is finished in the reach of drive fork with the hinge, the ratchet be arranged on the screw rod lower end of determining to rely on of its depth of cut is finished, and it is that section is finished in the upper and lower to-and-fro movement in center with the hinge that the crank connecting link in the section movement drives the fork that section preparation is housed; In addition, impaired in order to prevent the sample surface with the cutting knife friction, whenever finishing once section must have backhaul to make a concession action, ratchet, ratchet so just need be set and by the yielding mechanism that cam, lever and connecting rod are formed, exist complex structure, the time-consuming shortcoming of adjustment.

The purpose of this utility model provides a kind of simple in structure, the microtome of section precision height and stable performance.

The utility model is to realize like this, it comprises casing, handwheel, frame, section knife rest, slicer, feed rod, fork, connecting rod, specimen holder, screw rod, hinge and the refrigeration system of being made up of compressor, condenser, handwheel is connected by the fork of connecting rod with the band sample, it is characterized in that stepper motor is connected with feed rod by screw rod, and the horizontal feed of control fork.

The utility model has been owing to adopted stepper motor to be connected with feed rod by screw rod, and controls the horizontal feed of fork, saved gear train, depth of cut set mechanism, mechanism is made a concession in the sample backhaul and mechanism is made a concession in the ratchet backhaul, have simple in structure, accurate, the stable advantage of moving.
