Abstract: A portable case having a mechanism capable of converting said case into a trolley. The mechanism is formed from basically two related sets of components, including base members connected to the sides of the case and each capable of extending a forward end beyond one end of the case, and a handle structure having arm members longitudinally slidable in relation to the base members and capable of being pivoted and locked at an angle with respect to the base members. In one embodiment, wheels are supported on the rear of the arm members so as to project downward therefrom when the arm members are pivoted and locked in their trolley position. In other embodiments, wheels are supported near the forward end of the base members. With both configurations, the wheels support the entire case when the locked arm members are tilted forward for trolley use.

Abstract: The invention relates to an improved method and means for closing an incision with surgical clips wherein the clips have a preformed preliminary skin hooking portion and a portion deformable on application to hook the skin on the opposite side of the incision whereby the clip becomes a surgical tool for holding the skin on one side of the incision while the closing of the incision by the clip is being carried out.
