1. A laparoscopic medical device comprising:
an end effector assembly having an end effector;
a rotatable drive assembly coupled to a proximal portion of the end effector;
a drive tube housing within which the rotatable drive assembly is disposed;
a knob locking assembly coupled to the rotatable drive assembly and having a lock configured to switch between a locked state in which the lock regulates movement along the drive tube housing and a released state in which the lock does not regulate movement along the drive tube housing;
wherein the knob locking assembly is configured to move along the drive tube housing with the rotatable drive assembly in the released state and is configured to rotate with respect to the drive tube housing with the rotatable drive assembly in the locked state.
