Abstract:
A medical instrument for endoscopic removal of the saphenous vein, comprising:an elongated shaft; a spatula tip at a distal end of said shaft; a handle disposed in a proximal region of said shaft and affixed thereto, said handle projecting laterally from said shaft; and an endoscopic optical system comprising an eyepiece cup arranged at a proximal end of said instrument, wherein said handle is joined to said shaft in such a way that an outer side of said instrument facing away from said handle has a continuous straight surface that, from the distal to the proximal end, is free of projections; said eyepiece cup is arranged on an eyepiece housing of said endoscopic optical system which has an outer side, facing away from said eyepiece cup, that approximately aligns with said outer side of said instrument facing away from said handle; a longitudinal center axis of said eyepiece cup is inclined with respect to a longitudinal center axis of said shaft at an angle of less than 90Â°; a longitudinal center axis of said handle and said longitudinal center axis of said shaft define a first plane; said longitudinal center axis of said eyepiece cup and said longitudinal center axis of said shaft define a second plane; and said first plane is inclined with respect to said second plane at an angle of less than 90Â° in either a clockwise or counterclockwise direction.
