Description
Technical Field
The invention belongs to the field of pathological microtomes, and relates to a signal acquisition device of a pathological microtome.
Background
The pathological section is a physical specimen which is prepared and processed by a specific process and is used for observation under a microscope and is taken from pathological tissues of a diseased organism when a patient performs operation in a hospital. In modern medicine, especially in the diagnosis of neoplastic disorders, pathological sections are an essential important element. The pathological microtome is a key device for preparing slices, and the performance and the precision of the pathological microtome are directly related to the preparation quality of a specimen of pathological tissues and the working efficiency of a pathologist. With the progress of technology, traditional purely mechanical slicing machines are eliminated gradually, the slicing requirements of high quality and high efficiency cannot be met, and the semi-automatic slicing machine with electromechanical integration is mainly used as the dominant point.
The intellectual property office of China in 2 months and 23 days in 2018 discloses a transmission feeding device of a pathological section machine, the publication number is CN207036528U, and the working principle is that a crank slide block mechanism on a hand wheel shaft is driven by the rotation of a large hand wheel on the right side, so that a vertical transmission unit reciprocates up and down, and a specimen tissue is driven to reciprocate up and down. The signal acquisition device which follows the control device transmits different action signals to the relevant control main board, the control main board converts the action signals into different pulse signals and transmits the different pulse signals to the motor driver, the driver drives the stepping motor to do different rotation actions according to the different pulse signals, the horizontal feeding unit is driven to do various actions of advancing or retreating, and the vertical transmission unit is combined with the up-and-down reciprocating motion, so that the horizontal feeding unit becomes a complete series of slice feeding actions.
The common signal acquisition control device generally adopts a resistance type displacement sensor, and the basic principle is that the change of the measured physical quantity is converted into the change of a resistance value corresponding to the change, and then the measured change is reflected after passing through a corresponding measuring circuit. When the slice reciprocates up and down, the electric brush is driven to reciprocate up and down on the surface of the electronic ruler to collect signals, and in the use process, the electric brush and the electronic ruler are always contacted with each other and generate friction. After the use for a long time, the electric brush and the electronic ruler are worn to cause insensitive contact or failure, so that the slicing machine cannot be used normally; in the process, the lead connected with the electric brush and playing a role in data transmission synchronously moves up and down in a reciprocating mode, after the frequency of use is high, the data transmission lead can generate fatigue failure, and the slicer can not be normally used. Again, in use, the brushes and the electronic ruler always contact each other and generate friction, and noise is also generated to disturb operators.
