摘要： A device for retracting edges of an incision in a surface to form an opening including: a flexible, tubular skirt having an upper end, a lower end, and a channel therebetween; a ring connected to the lower end of the skirt for maintaining the lower end in an open configuration and defining an exit opening to the channel; and an inflatable collar connected to the skirt and surrounding the upper end. The ring is designed to fit through the incision and remain under the surface when it is oriented parallel to surface. The collar, when inflated, maintains the upper end in an open configuration and defines an entry opening to the channel. During use, the ring is inserted through the incision and the collar is inflated while remaining outside of the incision, thereby drawing the skirt against the edges of the incision and retracting the edges of the incision to form the opening. The retracting device can be included in a surgical access port, which further includes a flexible sleeve connected to at least one of the inflatable collar and the skirt, extending the channel from the exit opening of the skirt to an open end of the flexible sleeve distal to the skirt. The device can include a light source in the vicinity of the exit opening.

摘要： A drive head for a bolt, fastener, coupling, nut or other driveable head made from a less malleable metal such as a powder metal nickel alloy. The drive head has an upper drive portion having at least six convex corners spaced around the outer periphery thereof, each corner terminating in an edge. The drive head also has a lower flange portion adjacent to the drive portion and having an edge extending radially outwardly to at least the edge of each corner. The drive portion and the flange portion of the drive head is formed by subjecting a blank having a generally circular head to electrochemical machining (ECM). A tool is also provided for the ECM method to form the drive portion and flange portion of the drive head.
