1. A medical device, comprising:
a handle, including an axle;
a device shaft extending from the handle to a distal end; and
a control device, wherein the control device is coupled to the handle and includes:
a knob, wherein the knob is rotatable relative to the handle;
a control shaft extending from the knob, wherein the control shaft includes a radial extension, and wherein the control shaft includes first and second projections extending from the radial extension;
a first spring clutch and a second spring clutch, wherein each of the first and second spring clutch includes a first leg and a second leg;
a spool, wherein the spool is rotatable relative to the axle, and wherein the spool defines first and second gaps, and wherein the first and second projections are configured to be positioned within the first and second gaps; and
one or more wires coupled to the spool,
wherein rotation of the knob is configured to rotate the control shaft, causing the spool to rotate and the one or more wires to move, wherein rotation of the knob in a first direction causes the first projection to contact the first leg of the first spring clutch to loosen the first spring clutch, and wherein rotation of the knob in the first direction causes the second projection to contact the first leg of the second spring clutch to loosen the second spring clutch, and
wherein further rotation of the knob in the first direction causes (1) the first leg of the first spring clutch to contact a first stop surface of the spool adjacent the first gap, (2) the first leg of the second spring clutch to contact a second stop surface of the spool adjacent the second gap, and (3) the spool to rotate in the first direction.
