Abstract
A support arm for a heart stabilizer that can be used to stabilize a heart during a beating heart coronary artery bypass graft procedure. The support arm may have an arm that is coupled to a table mount and an end effector. The table mount is adapted to be mounted to the rail of a surgical table. The end effector is adapted to hold the heart stabilizer. The arm may be adjustable to allow an end user to adjust the position of the end effector.
Claims23
A support arm assembly, comprising:
- a table mount;
- an arm coupled to said table mount;
- an end effector coupled to said arm, said end effector having a stationary jaw member, a retractable jaw member biased to move toward the stationary jaw member;
- and
- a heart stabilizer having a shaft, the shaft held between the retractable jaw member and the stationary jaw member without rotation of a threaded fastener.

A support arm assembly, comprising:
- a table mount adapted to be secured to the table;
- a first linkage coupled to said table mount;
- a second linkage pivotally coupled to said first linkage;
- a third linkage pivotally coupled to said second linkage;
- an end effector pivotally coupled to said third linkage, the end effector having a stationary jaw member, a retractable jaw member biased to move relative to the stationary jaw member;
- and
- a heart stabilizer having a shaft, the shaft held between the retractable jaw member and the stationary jaw member without rotation of at fastener.
4 more elements
A method for coupling a heart stabilizer to a table, comprising:
- mounting a support arm to the table;
- adjusting a position of an end effector of the support arm, the end effector having a retractable jaw member;
- retracting the jaw member, the retraction creates a spring force;
- inserting a heart stabilizer into the end effector;
- and
- releasing the jaw member so that the spring force returns the jaw member and secures the end effector to the heart stabilizer.
