1. A medical device for surgically removing tissue, comprising:
a hand piece;
a blade assembly removably attachable to the hand piece, the blade assembly including:
a rotatable resection member configured to rotate and surgically remove tissue from a target tissue site; and
a coupling assembly including a blade assembly locking member configured to:
detachably couple the blade assembly to the hand piece;
operatively enable or disable a rotation of the blade assembly relative to the hand piece, the rotation of the blade assembly causing a change in rotating angle of the blade assembly relative to the hand piece; and
secure the rotating angle of the blade assembly,
wherein the coupling assembly includes a first rotatable hub configured to be manually activated to cause the change in rotating angle of the blade assembly relative to the hand piece,
wherein the hand piece includes an actuator configured to be manually activated, separately and independently of the manual activation of the first rotatable hub, to cause a change in orientation of a resection window on the blade assembly to expose the rotatable resection member.
