Paraffin section transferring and developing apparatus, sectioning device and method for paraffin sectioning

Abstract

The invention provides a paraffin slice transfer and unfolding instrument. The paraffin slice transfer and unfolding instrument comprises a bracket, a conveying mechanism, a refrigeration mechanism, and an electrostatic mechanism, the conveying mechanism comprises a conveyor belt and a power unit, the conveyor belt is paved on the surface of the bracket, the power unit drives the conveyor belt tomove, a cool air inlet of the refrigeration mechanism is arranged in an inner space of the bracket below the conveyor belt, and the tail end of the electrostatic mechanism is in contact with the conveyor belt and provides static electricity for the electrostatic mechanism or eliminates the static electricity thereof. The invention further provides a slicing device, comprising a fixed seat, and a specimen holder and a blade, which are arranged on the fixed seat, wherein the specimen holder is arranged on the fixed seat in a vertical movable manner, the slicing device further comprises the aboveparaffin slice transfer and unfolding instrument, the paraffin slice transfer and unfolding instrument is arranged on one side of the blade, and the first end of the conveyor belt is close to the knife edge of the blade and receives a paraffin slice cut by the blade. The paraffin slice transfer and unfolding instrument in the scheme can smoothly absorb the paraffin slice; and the slicing device in the scheme can realize the automatic transfer and unfolding of the paraffin slice.

Description

technical field [0001] The invention belongs to the technical field of biomedical experimental instruments, and in particular relates to a paraffin section transfer and display instrument, a slicing device and a paraffin section method. Background technique [0002] Paraffin section is a common method of making slices in histology. It is often used to observe normal tissue cells or matrix, and can also be used to observe the structure and composition changes of pathological tissue cells or matrix. First, the biological tissue needs to be embedded in paraffin (abbreviated as "tissue wax block"), and then the tissue wax block is cut into thin slices with a paraffin microtome. The reciprocating cutting cuts out paraffin thin slices with a thickness of 5 to 10 microns. During the slicing process, the operator needs to hold the front end of the paraffin slice with tweezers for continuous sectioning to avoid wrinkles or overlapping of the slice. After cutting out a certain number...
