AI Technical Summary
Existing pathological sectioning devices are inadequate in terms of section thickness uniformity, resulting in poor section quality and affecting the accuracy of pathological analysis.
The design employs a threaded screw with sections of varying pitches. The blades mesh with these sections, achieving dynamic compensation through differentiated pitch design. This ensures that the blades are evenly distributed on the threaded screw, thereby improving the uniformity of the slice thickness.
By using a differentiated pitch design, the blades automatically tend to be evenly distributed on the threaded screw, which improves the thickness uniformity of pathological sections and enhances section quality and efficiency.
