1. A robotically controlled reamer, the reamer comprising:
a primary driveshaft configured to rotate about a first axis of rotation via a motor;
a cutting head coupled to a distal end of the primary driveshaft, the cutting head configured to rotate about a second axis of rotation, parallel to and laterally offset from the first axis of rotation, and a cutting depth of the cutting head controllable by a robotic arm; and
a retainer including a distal end configured for coupling to the primary driveshaft and a proximal end configured for coupling to the robotic arm, the retainer including a first portion defining a first longitudinal axis extending orthogonally to the primary driveshaft, the retainer including a second portion located distal to the first portion and defining a second longitudinal axis extending parallel to and laterally offset from the first longitudinal axis, the second portion being monolithically formed with the first portion such that the second portion remains in a fixed position relative to the first portion.
