Rotatable medical device

Abstract

Medical devices and methods for using medical devices are disclosed. An example medical device may include a tubular member having a lumen defined therein and a proximal end. A shaft may extend through the lumen. The shaft may have a distal end and a proximal end. An end effector may be attached to the distal end of the shaft. A handle may be coupled to the proximal end of the tubular member. The handle may include a base, a first hub member attached to the base, a second hub member coupled to the first hub member, and a cap attached to the second hub member.

         2 . The medical device of  claim 1 , wherein the second hub member comprises a first enclosure member and a second enclosure member attached to the first enclosure member. 
     
     
         3 . The medical device of  claim 1 , wherein the second hub member has a chamber formed therein. 
     
     
         4 . The medical device of  claim 3 , wherein the chamber is configured to receive a projection formed on the first hub member. 
     
     
         5 . The medical device of  claim 4 , wherein the second hub member is configured to rotate relative to the first hub member about the projection. 
     
     
         6 . The medical device of  claim 1 , wherein the second hub member is coupled to the cap with a threaded connection. 
     
     
         7 . The medical device of  claim 1 , wherein the second hub member is configured to compress onto the first hub member. 
     
     
         8 . The medical device of  claim 1 , wherein the second hub member is coupled to the cap with a snap fit connection. 
     
     
         9 . The medical device of  claim 1 , wherein the first hub member is coupled to the base with a threaded connection. 
     
     
         10 . The medical device of  claim 1 , wherein the shaft extends through the base, wherein the base has slot formed therein, and wherein a gripping member is disposed along the base and has a projection that extends through the slot and is attached to the shaft. 
     
     
         11 . The medical device of  claim 10 , wherein the gripping member is slidable along the base. 
     
     
         12 . The medical device of  claim 1 , further comprising a rotation member disposed at a proximal end of the base. 
     
     
         13 . The medical device of  claim 1 , wherein the first hub member is coupled to an outer surface of the base. 
     
     
         14 . The medical device of  claim 13 , wherein the second hub member is coupled to the outer surface of the first hub member. 
     
     
         15 . The medical device of  claim 14 , wherein the cap is coupled to the outer surface of the second hub member. 
     
     
         16 . A medical device comprising:
 a tubular member having a lumen defined therein and a proximal end;   a shaft extending through the lumen, the shaft having a distal end and a proximal end;   an end effector associated with the distal end of the shaft; and   a handle assembly coupled to the proximal end of the tubular member, the handle assembly including a rotation assembly, the rotation assembly consisting of a base, a first hub member coupled to an outer surface of the base, a second hub member coupled to the first hub member and rotatable relative to the first hub member, and a cap threadably coupled to the second hub member.   
     
     
         17 . The medical device of  claim 16 , wherein the second hub member has a chamber formed therein and wherein the chamber is configured to receive a projection formed on the first hub member. 
     
     
         18 . The medical device of  claim 17 , wherein the second hub member is configured to rotate relative to the first hub member about the projection. 
     
     
         19 . The medical device of  claim 16 , wherein the shaft extends through the base, wherein the base has slot formed therein, and wherein a gripping member is disposed along the base and has a projection that extends through the slot and is attached to the shaft. 
     
     
         20 . A medical device comprising:
 a tubular member having a lumen defined therein and a proximal end;   a shaft extending through the lumen, the shaft having a distal end and a proximal end;   an end effector associated with the distal end of the shaft; and   a handle coupled to the proximal end of the tubular member, the handle including a rotation assembly, the rotation assembly including a monolithic base and first hub member, a second hub member coupled to the monolithic base and first hub member and rotatable relative to the monolithic base and the first hub member, and a cap threadably coupled to the second hub member.
