发明名称 Instruments for stretching and/or expanding skin tissue
摘要 Instruments are provided, representative embodiments of which have a first and a second jaw, from each of which at least one engaging element, whose distal end is suitable for engaging the skin tissue to be stretched, protrudes; an elastic member connecting the jaws, stressing them against each other when subjected to a traction force; and elements for adjusting the distance separating the jaws in the absence of traction force on the elastic member.

主权项 1. An instrument for stretching and/or expanding skin tissue at the margins of skin lesions comprising: a first and a second jaw which have respective longitudinal axes and from each of which at least one engaging element, whose distal end is suitable for engaging said tissue, protrudes, a single elastic member associated with the instrument disposed between and connecting said jaws and having a longitudinal axis centrally arranged in said instrument wherein two symmetrical portions are defined, configured to urge the jaws against each other when subjected to a traction force, and elements for adjusting the distance separating said jaws in the absence of traction force on the elastic member, wherein said single elastic member has a first end fixed to the first jaw and a second end which is adjustably associated with the second jaw, and wherein said second jaw has a flat body and a front edge with a fissure facing a front edge of the first jaw, an opening, in at least one face perpendicular to said front edge of the flat body of the second jaw, communicating with said fissure and having side edges in which respective slots are present in the mid portion of the body, a pivot passing through said slots and said opening, and wherein the elastic member passes through the fissure, is wound around the pivot, and again passes through the fissure, whereby the second end of the elastic member protrudes from said fissure toward the first jaw to which the first end of the single elastic member is fixed, wherein the second jaw has only two major faces including a bottom major face facing the skin tissue, and wherein said first jaw, said second jaw and said single elastic member have coinciding longitudinal axes.
