Powered surgical apparatus, method of manufacturing powered surgical apparatus, and method of using powered surgical apparatus

Abstract

A powered surgical apparatus can be used with a source of irrigation fluid and a source of suction. The powered surgical apparatus can include a cutting blade assembly and a handle. The handle can include an upper portion defining a distal section connectable to the cutting blade assembly and a lower portion extending downwardly from the upper portion. The handle can be connectable to the source of irrigation fluid and the source of suction. The system can also include a manually actuable input device that provides at least one signal relevant to at least one operation of the system, and a controller that receives the at least one input signal and provides an output signal to perform the at least one operation of the system.

1 . A handle assembly usable as a powered surgical apparatus with a source of suction and a source of irrigation fluid, the handle comprising: 
 a movable cutting blade assembly that includes a rotatable inner tube and an outer tube, the inner tube defining a cutting surface and the outer tube defining a cutting window;    a handle including a distal section that is connectable to the movable cutting blade assembly, the handle including a proximal section defining a proximal end face that includes a suction coupling and an irrigation fluid coupling, the handle defining an irrigation fluid channel that extends from the irrigation fluid coupling of the proximal end face to the cutting blade assembly, the handle defining a suction channel extending from the suction coupling of the proximal end face to the distal section; and    a motor arranged within the handle, the motor adapted to drive the rotatable inner tube.    
   
   
       2 . The handle assembly of  claim 1 , further comprising a connector connectable to the proximal end face of the handle, the connector defining an irrigation fluid entry channel that is contiguous with the irrigation fluid channel of the handle.  
   
   
       3 . The handle assembly of  claim 1 , further comprising a connector connectable to the proximal end face of the handle, the connector defining a suction exit channel that is contiguous with the suction channel of the handle.  
   
   
       4 . The handle assembly of  claim 1 , wherein the irrigation fluid channel is substantially linear.  
   
   
       5 . The handle assembly of  claim 1 , wherein the suction channel is substantially linear.  
   
   
       6 . The handle assembly of  claim 1 , the distal section of the handle further comprising a manually rotatable member, the member being connectable to the outer tube such that manual rotation of the member results in rotation of the outer tube and thereby reorientation of the cutting window.  
   
   
       7 . The handle assembly of  claim 1 , the proximal end face of the proximal section of the handle further comprising a power coupling adapted to provide power to the motor.  
   
   
       8 . The handle assembly of  claim 7 , further comprising a connector connectable to the proximal end face of the handle, wherein the connector defines a power source channel that is contiguous with the power coupling and is connectable to a power source.  
   
   
       9 . A handle assembly usable as a powered surgical apparatus with a source of suction and a source of irrigation fluid, the handle assembly comprising: 
 a housing including a first end and a second end;    a movable cutting blade assembly connectable to said first end, the blade assembly comprising a rotatable inner tube arranged at least partially within an outer tube, the inner tube defining a cutting surface and the outer tube defining a cutting window;    a suction coupling formed on the second end, and an irrigation fluid coupling formed on the second end;    an irrigation fluid channel, defined by the housing, that extends from the irrigation fluid coupling of the second end to the cutting blade assembly of the first end;    a suction channel defined by the housing, extending from the suction coupling of the second end to the cutting blade assembly of the first end; and    a motor arranged within the housing, and interposing the first end and the second end, wherein the motor is adapted to drive the rotatably inner tube.    
   
   
       10 . The handle assembly of  claim 9 , further comprising a connector connectable to the proximal section of the housing wherein the connector defines an irrigation fluid entry channel that is contiguous with the irrigation fluid channel of the housing.  
   
   
       11 . The handle assembly of  claim 9 , further comprising a connector connectable to the proximal section of the housing wherein the connector defines a suction exit channel that is contiguous with the suction channel of the housing.  
   
   
       12 . The handle assembly of  claim 9 , wherein the irrigation fluid channel is substantially linear.  
   
   
       13 . The handle assembly of  claim 9 , wherein the suction channel is substantially linear.  
   
   
       14 . The handle assembly of  claim 9 , the distal section of the housing further comprising a manually rotatable member, the member being connectable to the outer tube such that manual rotation of the member results in rotation of the outer tube and thereby reorientation of the cutting window.  
   
   
       15 . The handle assembly of  claim 9 , the proximal section of the housing further comprising a power coupling adapted to provide power to the motor.  
   
   
       16 . The handle assembly of  claim 15  further comprising a connector connectable to the proximal section of the housing wherein the connector defines a comprising a power source channel that is contiguous with the power coupling and is connectable to a power source.
