Abstract
A shoulder hold-down is provided for use in securing at least a shoulder of a patient in position relative to a surgical frame. The shoulder hold-down includes a locking mechanism that is adjustable to afford positioning of a shoulder engaging portion for contacting the patient. The locking mechanism facilitates at least four (4) modes of adjustment to position the shoulder engaging portion relative to the patient.

A locking mechanism for use with a surgical frame, the locking mechanism comprising:
- an arm portion including a first shaft portion, a second shaft portion, and a first flange portion, the arm portion including a first end, an opposite second end, a mid-longitudinal axis extending through the first end and the second end, and a channel extending from at least adjacent the first end to at least adjacent the second end along the mid-longitudinal axis, the channel receiving portions of the second shaft portion therein, the first shaft portion including a first exterior surface, the second shaft portion including a second exterior surface, the first shaft portion adjacent the first end of the arm portion including a first aperture on a first side of the channel, the first shaft portion adjacent the first end of the arm portion including a second aperture on a second side of the channel, and the second shaft portion adjacent the first end of the arm portion including a third aperture;
- a handle portion having a clevis portion including a first lateral portion and a second lateral portion, the first lateral portion and the second lateral portion of the handle portion being spaced apart from one another, the first lateral portion of the handle portion including a fourth aperture and a first cam surface formed thereon, and the second lateral portion of the handle portion including a fifth aperture and a second cam surface formed thereon, end portions of each of the first shaft portion and the second shaft portion adjacent the first end of the arm portion being received between the first lateral portion and the second lateral portion of the clevis portion;
- a bracket portion and a second flange portion, the bracket portion including at least a third lateral portion and a fourth lateral portion, the third lateral portion and the fourth lateral portion of the bracket portion being spaced apart from one another, the second flange portion being positioned between the third lateral portion and the fourth lateral portion of the bracket portion, the third lateral portion of the bracket portion including a sixth aperture, and the fourth lateral portion of the bracket portion including a seventh aperture, the first lateral portion and the second lateral portion of the handle portion being received between the third lateral portion and the fourth lateral portion of the bracket portion;
- and
- one of a rod and a fastener extending through the first aperture, the second aperture, the third aperture, the fourth aperture, the fifth aperture, the sixth aperture, and the seventh aperture to attach the arm portion, the bracket portion, and the handle portion to one another;
- wherein the first cam surface and the second cam surface of the handle portion are contactable to at least one surface of the first flange portion, and movement of the handle portion from an unactuated position to an actuated position causes the first cam surface and the second cam surface to translate on the at least one surface, and simultaneously move the first contact surface of the first flange and the second contact surface of the second flange toward one another, and move the second shaft portion at least partially out of the channel in the first shaft portion to expand the first shaft portion and the second shaft portion relative to one another via interaction of the one of the rod and the fastener in the first aperture, the second aperture, the third aperture, the fourth aperture, the fifth aperture, the sixth aperture, and the seventh aperture.

A locking mechanism for use with a surgical frame, the locking mechanism comprising:
- an arm portion including a first shaft portion, a second shaft portion, and a first flange portion, the arm portion including a first end, an opposite second end, a mid-longitudinal axis extending through the first end and the second end, and a channel extending from at least adjacent the first end to at least adjacent the second end along the mid-longitudinal axis, portions of the second shaft portion being moveable into and out of the channel, the first shaft portion including a first exterior surface, the second shaft portion including a second exterior surface, the first shaft portion adjacent the first end of the arm portion including a first aperture on a first side of the channel, the first shaft portion adjacent the first end of the arm portion including a second aperture on a second side of the channel, and the second shaft portion adjacent the first end of the arm portion including a third aperture;
- a handle portion having a clevis portion including a first lateral portion and a second lateral portion, the first lateral portion and the second lateral portion of the handle portion being spaced apart from one another, the first lateral portion of the handle portion including a fourth aperture and a first cam surface formed thereon, and the second lateral portion of the handle portion including a fifth aperture and a second cam surface formed thereon;
- a bracket portion and a second flange portion, the bracket portion including at least a third lateral portion and a fourth lateral portion, the third lateral portion and the fourth lateral portion of the bracket portion being spaced apart from one another, the second flange portion being positioned between the third lateral portion and the fourth lateral portion of the bracket portion, the third lateral portion of the bracket portion including a sixth aperture, and the fourth lateral portion of the bracket portion including a seventh aperture;
- and
- one of a rod and a fastener extending through the first aperture, the second aperture, the third aperture, the fourth aperture, the fifth aperture, the sixth aperture, and the seventh aperture to attach the arm portion, the bracket portion, and the handle portion to one another;
- wherein, when the locking mechanism is assembled, the portions of the second shaft portion are received in the channel of the first shaft portion, end portions of each of the first shaft portion and the second shaft portion adjacent the first end of the arm portion being received between the first lateral portion and the second lateral portion of the handle portion, and the first lateral portion and the second lateral portion of the handle portion being received between the third lateral portion and the fourth lateral portion of the bracket portion, and
- wherein the first cam surface and the second cam surface of the handle portion are contactable to at least one surface of the first flange portion, and movement of the handle portion from an unactuated position to an actuated position causes the first cam surface and the second cam surface to translate on the at least one surface, and simultaneously move the first contact surface of the first flange and the second contact surface of the second flange toward one another, and move the second shaft portion at least partially out of the channel in the first shaft portion to expand the first shaft portion and the second shaft portion relative to one another.
