Abstract

A surgical retractor assembly for providing surgical exposure. The surgical retractor assembly consists of two frame segments connected by adjustable ratchet mechanisms to form a retractor frame. The ratchet mechanisms can be attached to tissue retractor blades that provide exposure of the wound when expanded, without the requirement of a direct connection/attachment to an operating table or bed frame. The tissue retractor blades are attached in a manner that is adjustable and facilitates the ability of the overall surgical retractor assembly to be raised or lowered with respect to the patient. The retractor frame also allows attachments of additional retractor blades or other surgical retractor accessories for additional surgical exposure.

A surgical retractor comprising:

an adjustable retractor frame having an adjustable circumference comprising a first frame segment and a second frame segment and two connectors;
the first frame segment and the second frame segment each comprising a first and a second substantially straight arm portion and a middle portion connecting the first and second substantially straight arm portions, the first and second substantially straight arm portion and the middle portion substantially in the same plane and each segment having a continuous fixed length, the long axes of the first and second substantially straight arm portions being parallel to each other and projecting to the same side of the middle portion, the middle portion forming a first and a second bend with the first and second substantially straight arm portions, respectively so that the long axis of the middle portion is perpendicular to the long axes of the first and second substantially straight arm portions, each frame segment having a top and bottom face with an inner edge and an outer edge;
the first frame segment and the second frame segment configured to connect to form said adjustable retractor frame when the first substantially straight arm portion of the first frame segment connects with the first substantially straight arm portion of the second frame segment and the second substantially straight arm portion of the first frame segment connects with the second substantially straight arm portion of the second frame segment;
the connectors configured to receive the first and second substantially straight arm portions of the first and second frame segments to form the adjustable retractor frame, wherein the connector can be in (i) an unlocked configuration that allows the substantially straight arm portions of the frame segments to move with respect to one another allowing the adjustable retractor frame to adjust or (ii) a locked configuration that fixes a substantially straight arm portion at a position relative to a substantially straight arm portion of the other frame segment;
and
two or more retractor blades coupled to the frame where the face of the retractor blade forms an angle with the plane of the frame.
