Feeding and retreating photoelectric precise regulating and controlling mechanism of biological tissue sliding table of slicer

Abstract

The invention relates to a feeding and retreating photoelectric precise regulating and controlling mechanism of a biological tissue sliding table of a slicer and belongs to the technical field of medical apparatus and instruments. The feeding and retreating photoelectric precise regulating and controlling mechanism comprises a hand wheel shaft, a hand wheel seat, a large hand wheel, a horizontal transmission sliding table and a base. The hand wheel seat is fixed to the base, and a guide rail through which the horizontal transmission sliding table moves vertically up and down is arranged on thebase. The mechanism is characterized in that an encoder and a data line are also arranged on the hand wheel seat. The encoder comprises a luminous element, a light-receptive element and a coded discarranged on the encoder body, the encoder body is fixed to the hand wheel seat, the luminous element and the light-receptive element are oppositely arranged on the encoder body with a gap, and the coded disc is fixedly connected to the hand wheel shaft, so that the coded disc is rotatably located between the luminous element and the light-receptive element. The feeding and retreating photoelectricprecise regulating and controlling mechanism provided by the invention is skillful in structure, convenient to operate and high in transmission precision, can improve the work efficiency and qualityof biological tissue slicing greatly and reduce the working strength of an operator, and has relatively high promotional value to an existing pathological microtome

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a photoelectric precision control mechanism for the feed and retreat of a biological tissue sliding table of a slicer. Background technique [0002] Pathological microtome is the key equipment for preparing pathological slices, and it has been widely used in modern medical field. During the operation of the pathological slicer, the pathological tissue specimens are installed on the horizontal transmission slide table, which is set on the vertical transmission guide rail, the pathological tissue specimens are installed on the end face of the horizontal transmission slide table, and the horizontal transmission slide table is attached to the wheel shaft. Through a transmission mechanism vertically reciprocating up and down in a guide rail, the pathological tissue specimen installed on the end face of the horizontal transmission slide moves back and forth with the...

AI Technical Summary

Problems solved by technology

Therefore, the traditional pathological microtome is often inefficient, and the operator must walk the full stroke for each slice, which also greatly increases the work intensity of the slice.
