US 11,998,231 B2 · Apparatus and method for mechanically disintegrating tissue into micrografts, and feeder piece used in connection with the disintegration of tissue

Abstract

For improving the quality of grated tissue, a method is presented for mechanically disintegrating tissue (2) into micrografts, in which method a blade part (3), which has a planar grater surface (3.1), and the tissue placed in a tissue holder are made to move relative to each other, and where the tissue is guided against the grater surface (3.1), characterised in that the tissue is guided against the grater surface (3.1) together with the tissue feeder piece so that the feeder piece (12) is disintegrated together with the tissue (2). The application also includes independent claims concerning an apparatus for mechanically disintegrating tissue into micrografts, and a feeder piece.

Dependent claims

An apparatus for mechanically disintegrating tissue into micrografts, comprising:

a blade part with a grater surface;
and
a tissue holder for supporting the tissue and for guiding the tissue against the grater surface, wherein the tissue holder comprises:
a guide space arranged in a body part of the tissue holder, wherein the guide space has at least one internal guide surface that is straight in a longitudinal direction of the guide space, wherein the guide space is at an angle with respect to the grater surface;
and
a tissue feeder piece arranged in the guide space and movable in the longitudinal direction, the tissue feeder piece defining a hollow, into which the tissue is placeable, wherein the tissue feeder piece is made from a sacrificial material and is arranged to be grated at least partially into a micrograft obtained from the tissue when the apparatus is used for disintegrating tissue.
