Abstract:
1. A spreadable medical instrument for endoscopic interventions comprising: a base body, a handle positioned on the base body, two spatula blades connected to the handle; and an adjustment mechanism for displacing said two spatula blades from a starting closed position wherein the two spatula blades are adjacent to each other into a working position wherein the two spatula blades are spreaded from each other by parallel and/or tipping displacement; wherein the two spatula blades have a proximal end positioned close to the handle, wherein at least one of the two spatula blades has a tapering at the proximal end, the tapering defines a gap at the proximal end between the two spatula blades in the starting closed position, and the gap opens up toward the proximal end; wherein the adjustment mechanism includes a first adjusting screw for parallel displacement of at least one of the two spatula blades into a parallel working position and a second adjusting screw for tipping displacement of at least one of the two spatula blades into an angled working position, the first adjusting screw and the second adjusting screw being positioned close to one another on the handle to allow simultaneous gripping of the handle and rotation of one or both of the first and second adjusting screws with one hand only, wherein the adjustment mechanism is a continuously adjustable screw-in mechanism for displacing the two spatula blades into a positions between the starting closed position and the working position, wherein rotation of one or both of the first and second adjusting screws directly displaces and fixes at least one of the two spatula blades into the working position, and wherein the first and second adjusting screws are self-locking.
