Sterile drape for robotic surgical equipment
View Patent ↗A sterile surgical drape for protecting a robotic surgical system includes an oblong drape of a clear flexible plastic material, which unfolds from a compact packet. From the proximal side of the main panel of the drape there project two pocket flaps, which are separated by a medial trough. The two pocket flaps are configured to slip over one another and together enclose the top of the control tower in an overlapping fashion, such that the robotic manipulator arms extend on either side of the main panel, while the camera/endoscope arm extends through the medial trough. The open ends of the pocket flaps are folded over to form cuffs, wherein a nurse can insert his/her hand to draw the flap over the top of the tower without touching non-sterile surfaces. The unfolding of the main panel is controlled by adhesive tabs or tear strips, so that the bottom of the panel does not engage the cart's wheels or the floor.
1. A sterile surgical drape for protecting a surgical robot, wherein the drape comprises:
a main panel comprising a substantially rectangular plastic sheet having a width between 5.5 and 7.5 feet and a first edge and a second edge opposite of the first edge, the first and second edges defining a length;
two flaps extending from the first edge and defining together with the first edge a center opening between the two flaps, each flap forming a pocket accessible through a flap opening along the first edge and each pocket comprising a folded cuff accessible through an opening above the flap opening, wherein each of the flaps is substantially square having a width of about 18 to 30 inches and the center opening has a height of about 18 to 30 inches and a width of about 24 to 36 inches:
wherein:
the sterile surgical drape is sized and constructed to cover a central tower of the surgical robot on at least one side of the central tower, wherein one or more robotic arms extend from the central tower, and the sterile surgical drape is sized and constructed not to impede with movement of the robotic arms;
each of the pockets is constructed to be capable of receiving a hand of a surgical attendant through the flap opening; and
the sterile surgical drape is constructed so that the flaps are capable of being slid, one overlapping the other, over a top of the central tower to cover the top of the central tower and to hold the sterile surgical drape in place, while the main panel and the flaps cover non-sterile surfaces of the central tower at least on one side and the central opening is sized and constructed so that at least one of the robotic arms can extend through the central opening.
2. The sterile surgical drape of claim 1 further comprising a plurality of adhesive tabs for holding the sterile surgical drape in a folded configuration during storage.
3. The sterile surgical drape of claim 2 , wherein the adhesive tabs are positioned on the sterile surgical drape so that the adhesive tabs are capable of holding the sterile surgical drape in a partially folded configuration while the sterile surgical drape is assembled on the surgical robot.
4. The sterile surgical drape of claim 3 , wherein the length of the main panel is shortened by folding in the partially folded configuration.
5. The sterile surgical drape of claim 1 , wherein the surgical robot comprises at least one robotic arm extending from a first side of the central tower, at least one robotic arm extending from a second side of the central tower, and at least one robotic arm extending from a front of the central tower, and wherein the sterile surgical drape is sized and constructed to cover the central tower without covering the robotic arms.
6. The sterile surgical drape of claim 5 , wherein the robotic arm extending from the front of the central tower comprises a camera, and wherein the robotic arm extending from the front of the central tower can extend through the central opening.
7. The sterile surgical drape of claim 1 , wherein the drape is folded into a compact packet having multiple folds that are secured by multiple adhesive tabs, and wherein the drape is constructed and assembled to be unfolded from the compact packet by successively releasing or removing the adhesive tabs so that the drape covers the at least one side of the central tower.
8. The sterile surgical drape of claim 1 , wherein the flaps are formed from plastic sheet.
9. The sterile surgical drape of claim 1 , wherein at least one robotic arm is attached to the central tower at an attachment point having a height, and wherein the length of the main panel substantially corresponds to the height of the attachment point.
10. The sterile surgical drape of claim 1 , wherein the length is between 6 and 8 feet.
11. The sterile surgical drape of claim 1 , wherein the drape is in a partially folded configuration comprising a plurality of folds on the main panel secured by adhesive tabs and the two flaps extending outwardly from the first edge of the main panel forming a horse-shoe shape.
