Bone graft harvesting

Abstract

The present disclosure includes apparatuses for a bone graft harvesting device. An example apparatus includes a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated and a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole.

What is claimed is: 
     
         1 . A bone graft harvesting apparatus, comprising:
 a blade tip including a proximal end and a distal end, wherein the distal end of the blade tip includes a number of blades configured to morcellate bone in response to being rotated; and   a lead tip located within the blade tip and configured to maintain the bone graft harvesting apparatus centered on a bone graft punch hole and to receive morcellated bone graft material.   
     
     
         2 . The apparatus of  claim 1 , wherein the number of blades on the blade tip comprise four blades. 
     
     
         3 . The apparatus of  claim 1 , wherein each blade of the number of blades include a tip and a curved surface. 
     
     
         4 . The apparatus of  claim 3 , wherein the curved surface of each blade is configured to move morcellated bone graft material away from the morcellated bone. 
     
     
         5 . The apparatus of  claim 1 , wherein the lead tip includes a number of windows configured to receive the morcellated bone graft material. 
     
     
         6 . The apparatus of  claim 1 , wherein the lead tip includes a nose that extends distally past the number of blades. 
     
     
         7 . The apparatus of  claim 6 , wherein the nose of the lead tip is tapered. 
     
     
         8 . A bone graft harvesting apparatus, comprising:
 a handle;   a shaft including a proximal end, a distal end, and a central lumen, wherein the proximal end of the shaft is coupled to the handle; and   a blade tip including a proximal end and a distal end, wherein the proximal end of the blade tip is coupled to the distal end of the shaft, and wherein the distal end of the blade tip includes a number of blades configured to morcellate bone and collect morcellated bone graft material.   
     
     
         9 . The apparatus of  claim 8 , wherein a central lumen of the shaft is configured to receive bone graft material. 
     
     
         10 . The apparatus of  claim 8 , wherein the shaft is detachable from the bone graft harvesting apparatus. 
     
     
         11 . The apparatus of  claim 8 , further comprising a mid-section positioned between the handle and the shaft, wherein the mid-section comprises an inner cylinder and an outer cylinder, and wherein the outer cylinder is rotatable relative to the inner cylinder. 
     
     
         12 . The apparatus of  claim 11 , wherein a vacuum port is coupled to the outer cylinder. 
     
     
         13 . The apparatus of  claim 12 , further comprising a number of gaskets positioned between the inner cylinder and the outer cylinder to provide a seal for the vacuum. 
     
     
         14 . A method for obtaining a bone graft, comprising 
 accessing an existing bone graft punch hole in a bone;   placing a lead tip of a bone graft harvester into the existing bone graft punch hole; and   rotating a blade tip in contact with the bone and morcellating the bone in response to rotating the handle.   
     
     
         15 . The method of  claim 14 , wherein collecting morcellated bone graft material includes the blade tip moving the morcellated bone graft material away from the morcellated bone in response to rotating the blade tip. 
     
     
         16 . The method of  claim 14 , wherein collecting morcellated bone graft material includes receiving the morcellated bone graft material within a central lumen of a shaft via a number of windows of the lead tip in response to rotating the blade tip. 
     
     
         17 . The method of  claim 14 , wherein collecting morcellated bone graft material includes providing vacuum via a vacuum port to aspirate the morcellated bone graft material. 
     
     
         18 . The method of  claim 14 , wherein collecting morcellated bone graft material includes storing the morcellated bone graft material within an inner cylinder coupled to the shaft. 
     
     
         19 . The method of  claim 18 , further comprising recovering the morcellated bone graft material from the inner cylinder. 
     
     
         20 . The method of  claim 19 , wherein recovering the morcellated bone graft material from the inner cylinder includes removing the shaft from the inner cylinder.
