Device for processing tissue to control thickness

Abstract

Devices and methods for processing animal or human tissue are provided. The devices may include a rod having a central axis and configured to simultaneously rotate around the central axis and move along the central axis. The device can further include a group of blades which are attached to the rod and positioned proximate the rigid support surface.

1 . A device for processing animal or human tissue, comprising:
 a rigid support surface for holding a tissue sample, the tissue sample having a top surface and a bottom surface;   a rod having a central axis and configured to simultaneously rotate around the central axis and move along the central axis;   a group of blades attached to the rod and positioned proximate the rigid support surface; and   at least one support member attached to the rod.   
     
     
         2 . The device of  claim 1 , wherein each blade in the group of blades is positioned such that each blade in the group of blades is oriented at an angle of between 45-90 degrees relative to the rigid support surface. 
     
     
         3 . The device of  claim 1 , wherein the central axis of the rod is parallel to the support surface. 
     
     
         4 . The device of  claim 1 , wherein a distance of the group of blades relative to the rigid support surface is adjustable. 
     
     
         5 . The device of  claim 4 , wherein the group of blades is positioned to provide a desired distance from the rigid support surface. 
     
     
         6 . The device of  claim 1 , wherein each blade in the group of blades has a center point. 
     
     
         7 . The device of  claim 6 , wherein the center point of the group of blades and the central axis of the rod are in a single plane parallel to the rigid support surface. 
     
     
         8 . The device of  claim 1 , further comprising a guiding member to move the tissue sample relative to the rod. 
     
     
         9 . The device of  claim 1 , further comprising a spring for attaching the rod to the at least one support member. 
     
     
         10 . The device of  claim 1 , further comprising at least one second support member attached to the rod. 
     
     
         11 . The device of  claim 1 , wherein the rod can rotate at an adjustable rate. 
     
     
         12 . The device of  claim 1 , wherein the rod comprises a group of grooves for attaching the group of blades. 
     
     
         13 . The device of  claim 1 , wherein the group of blades comprises five blades. 
     
     
         14 . The device of  claim 1 , wherein the support member has a cylindrical configuration. 
     
     
         15 . The device of  claim 1 , wherein the rod is configured to move at different speeds. 
     
     
         16 . The device of  claim 1 , wherein the tissue sample is a dermal tissue sample.
