Spreader for the atrium of the heart

摘要

A spreader for the atrium of the heart is disclosed, particularly for the exposure of the mitral valve, having a thin-walled axially continuous hollow retractor body, the diameter of which expands from a distal edge to a proximal edge. The wall of the retractor body is made of an elastically deformable flat material, preferably of a shape memory metal. At the proximal edge of the retractor body, a receptacle is arranged, into which a fixing rod for positioning and fixing the retractor body can be inserted.

主权项

1. A spreader for the atrium of the heart, comprising:
an axially continuous hollow retractor body with a wall and having a diameter that increases from a distal edge to a proximal edge, wherein the wall of the retractor body is an elastically deformable flat material, and wherein an axially continuous open gap is provided in a surface line of the retractor body so that the diameter of the retractor body can be reduced against its elasticity; a receptacle arranged at the proximal edge of the retractor body; a fixing rod pivotably connected to the retractor body; wherein the fixing rod can releasably be inserted into the receptacle; and wherein the wall includes a plurality of apertures arranged in a grid pattern; a second receptacle arranged at the proximal edge of the retractor body; and a guide rod inserted into the second receptacle and connected to the retractor body at a rigid angle.
