Surgical Tool
First Claim
1. A surgical tool for removing a portion of an implant within a human comprising:
- a housing;
a motor contained within the housing and coupled to the housing;
an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotateably engage an implant;
a counter-torque sleeve adjacent to the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end configured to couple to the implant relative to the counter-torque sleeve such that upon a rotational force to the implant the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing; and
an outer sleeve coupled to the housing and moveable between a first position and a second position, wherein in the first position the motor is in an off state.

Abstract
A surgical tool for removing a portion of an implant is provided that includes a housing, a motor contained within the housing and coupled to the housing, and an output shaft having a distal end and a proximal end opposite the distal end, wherein the proximal end is coupled to the motor and the distal end has an opening configured to rotateably engage an implant. The surgical tool further includes a counter-torque sleeve extending around the output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the housing and the distal end is configured to couple to the implant relative to the counter-torque sleeve. Upon a rotational force to the implant, the forces transmitted by the output shaft and the counter-torque sleeve are balanced by the coupling of the output shaft and counter-torque sleeve through the housing.

13. A tool for use during surgery comprising:
-
a housing; a motor disposed within the housing and connected to the housing; an output shaft having a proximal end and a distal end opposite the proximal end, wherein the proximal end is coupled to the motor and the distal end having an opening to engage an implant within a patient; a counter-torque sleeve having a proximal end and a distal end opposite the proximal end, the counter-torque sleeve coupled to the housing and overlying the output shaft, wherein the distal end includes an opening to engage the implant; an outer sleeve coupled to the housing and having switch having an on state and an off state; a trigger coupled to the housing and having a trigger switch having an on state and an off state, wherein the output shaft is in a rotateable state when the outer sleeve switch and trigger switch are in the on states. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
