Abstract
Surgical retractor apparatus is shown having at least two independently operable clamping locations for receiving pivot balls therein. These two clamping locations lock and unlock their respective pivot balls independent of locking of the other pivot ball. Furthermore, the locking mechanisms utilized to lock the pivot balls also utilize the lock the angular position of the extension rod relative to the clamp. An adjuster intermediate the clamping positions allows for the movement of the clamping location relative to each other.
Claims20
A retractor support apparatus comprising:
- an extension rod;
- a first and second pivot arm with a pivot ball respectively attached thereto;
- a coupler operably coupled to the extension rod, the extension rod angularly adjustable relative to the coupler, said coupler having
- a first and second clamping location, said first clamping location receiving and engaging said pivot ball of said first pivot arm, said second clamping location receiving and engaging said pivot ball of said second pivot arm, said first clamping location having a locked and a non-locked position wherein when in said locked position said first pivot arm is held securely by the first clamping location, said second clamping location having a locked and a non-locked position wherein when in said locked position said second pivot arm is held securely by the second clamping location, and
- a head which cooperates with the first and second clamping locations to fixedly set the angular position of the extension rod relative to the coupler when the first and second clamping locations are in the locked position.
A retractor support apparatus comprising:
- an extension rod;
- a first and second pivot arm with a pivot ball respectively attached thereto;
- a coupler operably coupled to the extension rod, said coupler having a first and second clamping locations each respectively defined intermediate a body and a leg, said first clamping location receiving and engaging said pivot ball of said first pivot arm, said second clamping location receiving and engaging said pivot ball of said second pivot arm, said first clamping location having a locked and a non-locked position wherein when in said locked position said first pivot arm is held securely by the first clamping location, said second clamping location having a locked and a non-locked position wherein when in said locked position said second pivot arm is held securely by the second clamping location, said first and second clamping locations pivotable relative to one another about a pivot when in the non-locked position, and
- a head which assists in retaining the extension rod relative to the first and second clamping locations when at least one of the first and second clamping locations is in the locked position.
