Trimsafe histology radius blade grossing knife

Abstract

A histology radius blade grossing knife is provided. The histology radius blade grossing knife has a blade mounting system adapted to operatively retain a histology radius trimming blade. The blade mounting system provides a retaining spine for engaging an upper edge of the trimming blade, wherein a rear portion of the retaining spine is securely sandwiched by retaining plates of the blade mounting system. Furthermore, the trimming blade provides notches and/or recesses for facilitating such operative association. Each histology radius trimming blade embodies a radiused or otherwise uniquely shaped heel for cutting and dissecting tissue

What is claimed is: 
     
         1 . A histology trimming blade for anatomical pathology applications, comprising:
 an elongated body defined by opposing lower and upper longitudinal portions, a front portion, and a rear portion;   the cutting edge and the upper edge disposed along opposing lower and upper longitudinal portions, respectively; and   the cutting edge having a relieved heel, wherein the relieved heel is defined by an absence of the elongated body for a run along the cutting edge of approximately 0.50 inches from the rear portion and a rise along the rear portion of approximately 0.16 inches from the cutting edge.   
     
     
         2 . The histology trimming blade for anatomical pathology applications of  claim 1 , wherein the relieved heel is further defined by a curved cutting edge having a radius of approximately one inch. 
     
     
         3 . The histology trimming blade for anatomical pathology applications of  claim 1 , wherein the relieved heel is further defined a straight cutting edge defined by the rise and run. 
     
     
         4 . The histology trimming blade for anatomical pathology applications of  claim 1 , wherein the relieved heel is further defined a first and second segmented cutting edges defined by the rise and run, wherein the segmented cutting edges are oblique relative to each other and the second segmented cutting edge is longer than the first segmented cutting edge. 
     
     
         5 . The histology trimming blade for anatomical pathology applications of  claim 1 , further comprising a lock notch in the upper portion. 
     
     
         6 . The histology trimming blade for anatomical pathology applications of  claim 5 , further comprising a stop notch in the rear portion.
