Autologous bone harvest during osteotomy and bone drilling procedures

Abstract

An apparatus and method for collecting particulate bone from the operating site during an osteotomy or bone drilling procedure so that it can be used subsequently to augment the bone fusion process. A bone cutting or drilling tool is provided with a module for collecting particulate bone simultaneously with cutting or drilling the bone. The collected particulate bone is transferred continuously to a sterile containment module and maintained under sterile conditions until it is prepared for re-use in the patient.

1 . Apparatus for collecting particulate bone for use in combination with a bone cutting or drilling tool during an osteotomy or bone drilling procedure, the bone cutting or drilling tool having a distal end with a bone cutting or drilling element, comprising 
 a collection module adaptable to the distal end, the module comprising an open distal end and a suction port opening into the distal end.    
   
   
       2 . The apparatus of  claim 1  further comprising an irrigation port opening into the distal end.  
   
   
       3 . The apparatus of  claim 1  wherein the collection module is flexible.  
   
   
       4 . The apparatus of  claim 1  wherein the bone cutting or drilling element extends beyond the distal end of said module.  
   
   
       5 . The apparatus of  claim 1  further comprising a means of containing the particulate bone.  
   
   
       6 . The apparatus of  claim 1  wherein the collection module is disposable.  
   
   
       7 . Apparatus for cutting or drilling bone and collecting particulate bone during an osteotomy or a bone drilling procedure comprising 
 a bone cutting or drilling tool having a distal end comprising a bone cutting or drilling element,    a collection module adapted to the distal end, the module comprising a suction port opening into the open distal end.    
   
   
       8 . The apparatus of  claim 7  wherein the module further comprises an irrigation port opening into the distal end.  
   
   
       9 . The apparatus of  claim 7  wherein the collection module is flexible.  
   
   
       10 . The apparatus of  claim 7  wherein the bone cutting or drilling element extends distally from said module through an open distal end of said module.  
   
   
       11 . The apparatus of  claim 7  wherein the bone cutting or drilling tool further comprises an irrigation port opening into the distal end.  
   
   
       12 . Apparatus for cutting or drilling bone and collecting particulate bone during an osteotomy or bone drilling procedure comprising 
 a bone cutting or drilling tool having a distal end comprising a bone cutting or drilling element and a suction port    a collection module adapted to the distal end, said module being sealingly engaged with the tool at the proximal end of the module and having an opening at the distal end of the module wherein the bone cutting or drilling element can extend distally through the opening and beyond the distal end of the module, and the suction port is in suctioning communication with the opening.    
   
   
       13 . The apparatus of  claim 12  wherein the bone cutting or drilling tool further comprises an irrigation port opening into the distal end and the irrigation port is in irrigating communication with the opening.  
   
   
       14 . The apparatus of  claim 12  wherein the collection module is flexible.  
   
   
       15 . The apparatus of  claim 12  wherein the collection module is disposable.  
   
   
       16 . A method of assembling an apparatus for cutting or drilling bone and collecting particulate bone during an osteotomy procedure or bone drilling comprising affixing to the distal end of a bone cutting or drilling tool, the distal end comprising a bone cutting or drilling element, a collection module having an open distal end, the bone cutting element capable of extending distally through said open distal end, the module or the tool comprising a suction port in suctioning communication with said open distal end.  
   
   
       17 . The method of  claim 16  wherein the module or the tool further comprise an irrigation port opening into said open distal end and in irrigating communication with said open distal end.  
   
   
       18 . A method of collecting particulate bone created at the operating site during an osteotomy or bone drilling procedure comprising cutting or drilling the bone with a bone cutting or drilling tool having a distal end, the distal end comprising a bone cutting or drilling element and a collection module, the bone cutting element extending distally from an open distal end of the collection module during cutting, the module or tool comprising a suction port opening into the open distal end, and suctioning the particulate bone from the operating site into the collection module.  
   
   
       19 . The method of  claim 18 , wherein the module or tool further comprises an irrigation system having an irrigation port opening into the distal end, further comprising irrigating the operating site during the osteotomy or bone drilling procedure.
