Abstract

A retractor ring assembly includes a ring holder that has a first selectively engaged connection and a second selectively engaged connection. A first and second ring portion each has a proximal end and a distal end. The proximal end of the first and second ring portions are selectively connected to the respective first and second selectively engaged connections of the ring holder. The distal end of the first ring portion has a third selectively engaged connection. The distal end of the second ring portion has a fourth selectively engaged connection. The third selectively engaged connection and the fourth selectively engaged connection are connectable to form a reinforced closed ring configuration, and are disconnectable to form an open ring configuration.

Dependent claims

A retractor ring assembly comprising:

a ring holder having a first selectively engaged connection and a second selectively engaged connection, wherein each of the first selectively engaged connection and the second selectively engaged connection are connected to the ring holder with a ball joint connection;
a first ring portion having a proximal end and a distal end, the proximal end being selectively connected to the first selectively engaged connection of the ring holder, the distal end having a third selectively engaged connection;
and
a second ring portion having a proximal end and a distal end, the proximal end being selectively connected to the second selectively engaged connection of the ring holder, the distal end having a fourth selectively engaged connection, wherein the third selectively engaged connection and the fourth selectively engaged connection are connectable to form a reinforced closed ring configuration, and are disconnectable to form an open ring configuration, wherein the first selectively engaged connection has a sleeve including a channel therein, and the second selectively engaged connection has a sleeve including a channel therein, wherein the sleeve of each of the first selectively engaged connection and the second selectively engaged connection has an opening through a wall thereof.
