Automatic positioning device for cutting three-dimensional tissue in living or fixed samples. Proof of concept

Area of Science:

• Biology
• Histology
• Anatomy
• Biochemistry
• Pharmacology

Background:

• Tissue study is crucial for morphological and functional research.
• Traditional microtomes and vibratomes are limited in providing 3D tissue structures.
• Existing methods often fail to capture the complete 3D architecture of tissue samples.

Purpose of the Study:

• To introduce an automatic positioning device for 3D cutting of tissue samples.
• To enable precise sectioning of both living and fixed biological tissues.
• To overcome the limitations of conventional tissue slicing instruments.

Main Methods:

• Development of an automated positioning system for tissue samples.
• Integration of an electromechanical system with motors and gears for sample orientation.
• Utilized movement sensors to verify the accuracy of sample orientation changes.

Main Results:

• The device allows for controlled orientation changes of tissue samples.
• Movement sensors confirmed the precision of the automated positioning system.
• The system facilitates sectioning along multiple planes and directions.

Conclusions:

• The novel device enables comprehensive 3D analysis of tissue samples.
• It maximizes the surface area of tissue tracts within slices.
• This advancement supports improved research in histology, anatomy, biochemistry, and pharmacology.
