Abstract: The present invention provides an improved surgical retractor system useful for holding tissue away from a surgical site during a medical or dental procedure. In one embodiment, the surgical retractor system is comprised of a tubular member, such as a cannula, and a retractor member. In an embodiment, the retractor member may be ring shaped. The retractor member preferably may have an opening therethrough for receiving the cannula. An engaging member associated with the retractor member may be provided for rotatably engaging the cannula. In one embodiment, the cannula may have external threads that are releaseably engaged with the engaging member and allows the degree or amount of tissue retraction to be adjusted. The cannula may be configured to be used with and secured to a handle to facilitate using the retractor system. A method of using the retractor system is also disclosed.

Abstract: The present invention provides an improved handle which may be used to releaseably hold various types of surgical instruments employed in medical or dental procedures. The handle is comprised of a grasping portion and a lock assembly that contains a retractable slider pin designed to engage one or more indentations provided with instruments intended for use with the handle. The lock assembly may be provided with at least one biasing member which holds the pin in an extended position thereby locking the surgical instrument to the handle. The instrument may be removed from the handle or rotated by the user retracting the pin to release the instrument from the handle. A system and a method of interchangeably using surgical instruments in the handle is also disclosed.
