Claim:
A device for stretching regions of tissue, comprising: multiple plate-like bodies, said plate-like bodies being arranged lying opposite on a tissue to be stretched, at least one pulling thread joining said oppositely arranged plate-like bodies, at least one tensioning device arranged on at least one of said plate-like bodies, said tensioning device being connected to said at least one pulling thread and serves for applying a tensile force to said at least one pulling thread, and a thread guidance being disposed on said plate-like bodies for guiding said at least one pulling thread joining said plate-like bodies, said guidance serves for guiding a movement of said plate-like bodies towards one another when said pulling thread is tensioned by said at least one tensioning device; wherein a plurality of said plate-like bodies is adapted for attaching on one side of opposite sides of said tissue and a single plate-like body of said plate-like bodies is adapted for attaching on an opposing side of said opposite sides, said single plate-like body having said at least one tensioning device, each of said plurality of said plate-like bodies being joined to said single plate-like body by a separate pulling thread; and wherein said single plate-like body, having arranged said tensioning device thereon, has at least one guiding location by means of which each pulling thread is fed to said tensioning device and is wound up there at a first end of each pulling thread, and having at least one fixing location for a second end of each pulling thread, and wherein at least one of said plate-like bodies lying opposite to said single plate-like body has at least two abutments spaced laterally apart from one another, wherein said abutments, said at least one fixing location and said at least one guiding location are shaped as openings in said plate-like bodies, said pulling thread being guided across a plane of said plate-like bodies through said openings.
