Problems solved by technology

[0003] The known microtome uses a linear potentiometer to detect the forward and backward movement of the sample slider and the up and down movement of the sample holder. These detection sensors cannot be applied to the models for slicing frozen samples, because the freezing cabinet is relatively humid and the lowest temperature can reach - 35°C, condensation and frost will occur, resulting in damage to the linear potentiometer

Abstract

The invention relates to the technical field of medical equipment, and provides a slicing machine. The slicing machine comprises a slicing execution unit, a sample feeding executing unit and a sampleframe; the slicing execution unit is connected with the sample frame; the slicing executing unit comprises a hand wheel, a first transmission shaft, an eccentric mechanism and a rotary detecting element; the hand wheel, the first transmission shaft and the eccentric mechanism are connected in sequence; the eccentric mechanism is connected with the sample frame; the rotary detecting element is usedfor detecting rotation of the first transmission shaft to monitor the position of the sample frame; the sample feeding execution unit comprises a sample feeding mechanism, a first sensor and a secondsensor; the sample frame is connected with the sample feeding mechanism; and the first sensor and the second sensor are arranged in the advancing direction of the sample feeding mechanism. The slicing machine can arrange the rotary detecting element outside a cavity without generating the condensation and frosting conditions; and the working state is not limited by wheel rotation slicing or freezing slicing machine types.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a slicer. Background technique [0002] The pathological or scientific research slicer is used to cut biological tissue into thin slices ranging from 2 to 50um, and then observe the thin slices under a microscope for disease diagnosis. Specifically, these tissue samples need to be embedded in paraffin or frozen before cutting. [0003] The known microtome uses a linear potentiometer to detect the forward and backward movement of the sample slider and the up and down movement of the sample holder. These detection sensors cannot be applied to the models for slicing frozen samples, because the freezing cabinet is relatively humid and the lowest temperature can reach - At 35°C, condensation and frost will occur, resulting in damage to the linear potentiometer. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned sh...
