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.
Claims18
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
- said first and second clamping locations independently operable into their respective locked and non-locked positions, and placement of both the first and second locations into their locked positions secures the extension rod at a fixed angular position relative to the coupler.

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 camping 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, and
- an adjuster spaced from the pivot and located intermediate the first and second bodies,
- wherein said first clamping location is selectively moveable relative to the second clamping location upon actuation of the adjuster.

A retractor support apparatus comprising:
- an extension rod connected to a head;
- 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 and second clamping locations defined intermediate at least a first body and a first leg, said first body intermediate said first leg and said extension rod, said first leg moveable relative to said first body transitioning from a locked to a non-locked configuration, and said first leg having a locking surface and said first body having a bore therethrough, and said head is connected to the extension rod through the bore of the first body with said extension rod angularly positionable relative to the coupler;
- the first leg having a locking surface which contacts the head in a locked configuration at least setting the angular position of the extension rod relative to the coupler;
- and
- a second leg and a second body defining the second clamping bore, said second body having a bore extending therethrough, and the head being connected to the extension rod through the bore of the second body.
