Automatic biological tissue rapid slicing machine

Abstract

The invention discloses an automatic biological tissue rapid slicing machine. The machine comprises a base. An advancing slide rail and a push rod motor for driving the advancing slide rail to move are arranged on the base. An equipment seat body is arranged on the advancing slide rail, a clamping mechanism capable of clamping an embedded biological tissue is arranged on the equipment seat body, and an up-down driving mechanism capable of driving the clamping mechanism to move up and down is arranged in the equipment seat body. A longitudinal straight notch is formed in the bottom of a movableblade bearing, and a transverse sliding block is arranged in the longitudinal straight notch to move front and back and drive the longitudinal straight notch to move up and down at the same time. Theclamp stroke can be reduced, the number of walking cutting times each time is increased, and the structure is reasonable.

Description

technical field [0001] In particular, the present invention relates to biological tissue slicers. Background technique [0002] In the middle of the last century, with people's continuous understanding and research on diseases, in addition to diagnosing diseases from gross tissues with the naked eye, it is also necessary to diagnose diseases from tissue structure and cell changes, which requires biological tissues to be made into thin slices of about 5um. Observed under a microscope, thus produced a biological tissue slicer, and experienced the development stage of a common biological tissue slicer and a semi-automatic biological tissue slicer. The knife stepping motor, the knife seat installed on the guide rail, the blade installed on the knife seat, the knife feeding stepping motor is connected with the knife seat through the screw-nut pair, and the device can realize automatic knife feeding. [0003] However, the existing cutting method is that the clamp clamps the embed...

Problems solved by technology

[0003] However, the existing cutting method is that the clamp clamps the embedded biological tissue to feed and reciprocates up and down. When the biological tissue moves down once, the blade cuts out a thin slice of the embedded biological tissue and then resets it. , feed, with this design, the up and down stroke distance of the fixture is long, and the number of cuttings is small each time, which greatly reduces the cutting efficiency. It cannot provide a slicer that reduces the movable stroke of the fixture and increases the number of cutting times.
