Retractor Tool For Minimally Invasive Hip Replacement Surgery

A retractor for use in surgery, the retractor comprising:

• a) a handle configured to be held by a user;
• b) a wound contact plate comprising a proximal wound contact plate portion and a distal prong extending from the proximal wound contact plate portion, wherein the proximal wound contact plate portion has spaced apart front and back planar proximal plate faces providing a plate thickness extending to first and second plate edges;
• and
• c) a solid intermediate shaft comprising a shaft length-extending from a proximal shaft portion to a distal shaft portion, wherein the proximal shaft portion is connected to the handle along a first axis and the distal shaft portion is rigidly connected to the proximal wound contact plate portion along a second axis,
• d) wherein an intermediate bend portion of the shaft extends from the first axis to the second axis through a bend angle ranging from 70° to 130°,
• e) wherein a first plane is aligned along the second axis and at least the proximal wound contact plate portion rigidly connected to the distal shaft portion, the first plane bisecting the proximal wound contact plate portion between the front and back planar proximal plate faces and extending to the right and left plate edges, and
• f) wherein the distal prong of the wound contact plate extends either away from the second axis of the distal shaft portion or towards the first axis of the proximal shaft portion, and
• g) wherein the shaft has a round cross-section extending from the proximal shaft portion connected to the handle to the distal shaft portion connected to the proximal wound contact plate portion with a diameter of the round cross-section being less than a maximum width of the wound contact plate portion measured from the right plate edge to the left plate edge.
