Arthroscopic Resection Devices

Abstract

The present disclosure relates to a resection device. The resection device includes an outer tubular member; and an inner tubular member disposed within the outer tubular member, the inner tubular member including a burr having a body with flutes extending along a length of the body, the flutes including parabolic wave patterns located along surface edges of the flutes. In an embodiment, the parabolic wave patterns extend along entire lengths of the flutes. Other resection devices are also disclosed.

1 . A resection device comprising:
 an outer tubular member; and   an inner tubular member disposed within the outer tubular member, the inner tubular member including a burr having a body with flutes extending along a length of the body, the flutes including parabolic wave patterns located along surface edges of the flutes.   
     
     
         2 . The resection device of  claim 1  wherein the parabolic wave patterns extend along entire lengths of the flutes. 
     
     
         3 . A resection device comprising:
 an outer tubular member; and   an inner tubular member disposed within the outer tubular member, the inner tubular member including a burr having a body with flutes extending along a length of the body and a tip with flutes, wherein the tip and the body include a different number of flutes.   
     
     
         4 . The resection device of  claim 3  wherein the body has a higher number of flutes than the tip. 
     
     
         5 . The resection device of  claim 3  wherein the body has a lower number of flutes than the tip. 
     
     
         6 . The resection device of  claim 3  wherein flutes on either the body or the tip include parabolic wave patterns located along surface edges of the flutes. 
     
     
         7 . The resection device of  claim 3  wherein the device further includes a transition piece located between the inner tubular member and the burr, the transition piece including a proximal portion and a tapered distal portion. 
     
     
         8 . The resection device of  claim 1  wherein the device further includes an opening located between the inner tubular member and the burr. 
     
     
         9 . The resection device of  claim 8  wherein the opening leads to a passageway, the passageway extending along a length of the inner tubular member. 
     
     
         10 . A resection device comprising:
 an outer tubular member; and   an inner tubular member disposed within the outer tubular member, the inner tubular member including a burr having a body with flutes extending along a length of the body and a tip with flutes, wherein the tip and the body include a different number of flutes, the flutes on either the body or the tip including parabolic wave patterns located along surface edges of the flutes.
