Abstract A surgical retractor is to be mainly used for dissection of the internal mammary artery. It is fixed to the side of the operating bed by a clamp which can be moved over the rail for the desired place. It's pole will be at either side that internal mammary artery is intended to be dissected, side arm of the pole will be over the patient and holding the crank mechanism, by placing the hooks of the retractor at the edge of the sternum after being split at the middle, and cranking the handle. The crank portion of the retractor, which is adjustable over the side arm of the pole, will pull and elevate the side of the chest and hold it in position for the time that is needed for the dissection of the internal mammary artery. Adjustment can be done with the crank part for better vision. After completion, release of the lever would allow the crank mechanism to be turned in the opposite direction, counter clockwise, the cord to become loose and the hooks to be free. The retractor can be removed by releasing it from the side of the bed by the loosening of the holding clamp. This retractor can be used for any other procedures that require elevation and retraction of part of the chest. A different type of pole (rod-shaped) and a different attachment for the crank mechanism can be used that would be adjusted easier by one screw.

Claim 1
Independent Claim
201 words
A surgical retractor device particularly adapted for use in thoracic procedures where it is desired to urge the sternum both laterally outwardly and vertically upwardly such as for mammary artery dissection, said device comprising a vertically extending member having a lower end secured relative to the patient support laterally outwardly of such patient and an upper end vertically above the position of the sternum of such patient, an elongate rigid member extending generally parallel to the sternum, a pair of spaced apart hooks having one end flexibly secured to said rigid member at spaced apart points and having a hook means on the distal and adapted for attachment over the split sternum, flexible retraction means having one end secured to said rigid member between said points and the other end operably secured to said vertically extending member, and means for retracting said flexible means away from said sternum by crank mechanism that is secured to said elongate rigid member and operates by turning handle to crank and hold at desired position toward said vertically extending member whereby said split sternum section is urged both vertically upwardly and laterally outwardly by both of said spaced apart hooks carried by said rigid member.
