Abstract
An apparatus comprises a base configured to mount on a frame, a post coupled to the base and extending upwardly therefrom, a head support for supporting the head of a patient lying in a prone position on the frame, and a lockable joint coupled to the post and coupled to the head support to position the head support above the base. The lockable joint, when locked, prevents movement of the head support along the post and prevents movement of the head support relative to the post about a plurality of axes. The lockable joint, when unlocked, allows movement of the head support along the post and allows movement of the head support relative to the post about the plurality of axes.

An apparatus for attachment to a patient support frame to support a head of a patient lying in a prone position on the frame during surgery, the apparatus comprising:
- a base configured to mount on the frame,
- a post coupled to the base and extending upwardly therefrom,
- a U-shaped support,
- a lockable joint received on the post and movable vertically along the post and, the lockable joint coupled to the support, the lockable joint including a handle to move an actuator between a first position wherein the actuator acts on the lockable joint to lock the lockable joint such that the lockable joint does not move relative to the post while simultaneously locking the support such that the support does not move relative to the lockable joint and a second position wherein the lockable joint is free to move along the post and the head support is free to move relative to the lockable joint about a first axis and a second axis, wherein the second axis is not parallel to the first axis, and
- a foam block coupled to a portion of the U-shaped support for pivoting movement about a transverse axis, the foam block having a cutout in a region thereof corresponding to a patient's eyes, nose and mouth.
An apparatus for attachment to a patient support frame to support a head of a patient lying in a prone position on the frame during surgery, the apparatus comprising:
- a base configured to mount on the frame,
- a post coupled to the base and extending upwardly therefrom,
- a head support for supporting the head of a patient lying in a prone position on the frame, and
- a lockable first joint received on the post the lockable first joint supporting the head support and movable vertically along the post, the lockable first joint including a first handle to move an actuator between a first position wherein the actuator acts on the lockable first joint to lock the lockable first joint to the post such that the lockable first joint cannot move relative to the post while simultaneously locking the head support such that the head support cannot move relative to the lockable first joint and a second position wherein the lockable first joint is free to move along the post and the head support is free to move relative to the lockable first joint about a first axis and a second axis, wherein the second axis is not parallel to the first axis.
An apparatus for attachment to a patient support frame to support a head of a patient lying in a prone position on the frame during surgery, the apparatus comprising:
- a base configured to mount on the frame, wherein the base includes a pair of longitudinally-extending and transversely-spaced side portions and a cross portion extending transversely between the side portions,
- a post coupled to the base and extending upwardly therefrom,
- a head support for supporting the head of a patient lying in a prone position on the frame,
- a lockable first joint received on the post and movable along the post and supporting the head support, the lockable first joint including a first handle to move an actuator between a first position wherein the actuator acts on the lockable first joint such that the lockable first joint cannot move relative to the post and simultaneously locking the head support such that the head support cannot move relative to the lockable first joint and a second position wherein the lockable first joint is free to move along the post and the head support is free to move relative to the lockable first joint about a plurality of axes, and
- a lockable second joint coupled to the cross portion and coupled to the post, wherein the lockable second joint, when locked, prevents lateral movement of the post along the cross portion, and the lockable second joint, when unlocked, allowing lateral movement of the post along the cross portion.
An apparatus for attachment to a patient support frame to support a head of a patient lying in a prone position on the frame during surgery, the apparatus comprising:
- a base,
- a post,
- a head support, and
- a lockable joint received on the post, the lockable joint supporting the head support, the lockable joint including (i) a body, (ii) an actuator, (iii) a lock movable relative to the body, and (iv) a single handle acting on the actuator to move the actuator between a first position wherein the actuator causes the lock to act on the post and the head support such that the body cannot move relative to the post and the head support cannot move relative to the body and a second position wherein the body is free to move in two directions along the post and the head support is free to move relative to the body about three non-parallel axes.
