Surgical retractor having improved blades
First Claim
1. A system for use in a surgical procedure, comprising:
- a retractor having a plurality of retractor arms thereon and a segment interconnecting said retractor arms wherein said retractor arms are movable with respect to each other and include top and bottom surfaces thereon wherein said bottom surface of each of said arms includes a plurality of elongate slots having a blade engaging surface on said bottom surface of said arms; and
a plurality of blades each having an upper surface with a raised surface thereon and said upper surface of said blades being sized to be slidably contacting with said blade engaging surface of said slot to allow horizontal movement therebetween and said blades further having at least one downwardly extending blade element thereon.

Abstract
The present invention relates to surgical retractors having improved blades for use, on the retractor and devices for stabilizing a predetermined area of the body during a surgical procedure, more particularly to surgical retractors and stabilizing devices used in connection with minimally invasive coronary artery bypass grafting surgical procedures, and more specifically to surgical retractors and stabilizing devices especially configured for use with each other for such surgical procedures wherein the retractor includes a plurality of grooves on the bottom surface thereof and a plurality of blades having a member that is releasably received in the grooves and which also allows for the pivotal movement of the blades relative to the arms of the retractor and further including nesting blades having a third section which is generally linear and second sections which are preferably curved about 180 degrees to allow for the simplified insertion of the blades into the chest incision and the providing for the secure and stable positioning of the retractor relative to the chest of the patient.

18. A system for use in a surgical procedure, comprising:
-
a retractor having a plurality of retractor arms thereon and a segment interconnecting said retractor arms wherein said retractor arms are movable with respect to each other and top and bottom surfaces thereon wherein said bottom surface includes a plurality of ridged slots on said bottom surface of said arms; and
a plurality of blades at least one of which has an upper surface with a raised surface thereon and said upper surface of said at least one of said blades being sized to be in slidable contact with at least one of said ridged slots to allow horizontal movement therebetween and said at least one of said blades further having at least one downwardly extending blade element thereon;
a ball member that extends upwardly with respect to said raised member;
a blade element associated with said upper surface of said at least one of said blades and said blade element including a first section that is oriented generally parallel to at least one of the arms of the retractor;
a second section on said blade element wherein said second section includes a downward curve extending from said first section;
a third section on said blade element wherein said third section extends downwardly from said second section and is oriented generally perpendicularly to said first section; and
wherein each of said retractor arms include inner surfaces and said third section of said blade elements are generally aligned with the inner surface of at least one of the retractor arms and said second section extends beyond said inner surface of at least one of said retractor arms.
