Abstract
A clamp for attaching a medical device to an OR table rail, including two closable clamp jaws that close to an extreme position that leaves inadequate room for the rail. A handle actuates the jaws apart, and a spring biases them together through a range of jaw positions. A lock member is biased to swing through a range of lock positions in which it progressively engages and locks the jaw mechanism through its range of jaw positions. A pair of bars carries the medical device on the clamp, and allows it to be adjustably positioned with respect to the rail.
Claims11
A clamp for attaching a device to a mount structure, comprising:
- a clamp mechanism including a first clamp member connected to a second clamp member, the first and second clamp members being movable relative to one another between a first clamp-mechanism position and a second clamp-mechanism position, wherein the first clamp-mechanism position provides adequate clearance for the mount structure to be inserted between the clamp members, and wherein the second clamp-mechanism position leaves inadequate room for the mount structure between the clamp members;
- and
- an actuation mechanism including a handle that is movable between a first handle position and an extreme second handle position, and also including a bias member;
- wherein with the handle in its first position, the actuation mechanism is configured to actuate the clamp mechanism to the first clamp-mechanism position;
- wherein with the handle in its extreme, second position, the actuation mechanism is configured to actuate the clamp mechanism to the second clamp-mechanism position;
- and
- wherein with the handle in its extreme, second position, the bias member is configured to resiliently bias the clamp members toward their respective second clamp-mechanism positions.

- and
- an actuation mechanism including a handle that is movable between a first handle position and an extreme, second handle position, and further including a lock member movable relative to the clamp mechanism between a first lock-member position and a second lock-member position, and further including a bias member configured to bias the lock member toward its second position;
- wherein with the handle in its first position, the actuation mechanism is configured to actuate the clamp mechanism to its first position, and to actuate the lock member to its first position;
- wherein with the handle in its extreme, second position, the actuation mechanism is configured to actuate the clamp mechanism toward the second clamp-mechanism position;
- and
- wherein the clamp mechanism defines a lock-engagement surface configured such that, as the clamp mechanism moves through a range of clamp-mechanism positions toward the second clamp-mechanism position, the lock member can engage the lock-engagement surface in a range of lock-member positions progressing toward the second lock-member position.
