The invention relates to a surgical suture positioning system for closing an opening inside an intracorporeal tissue wall, comprising an elongated shaft (3) which has a distal shaft region (5, 5'), on which a means (18) is provided which is made at least partially of an elastomer material is provided and which can be reversibly transferred from a position that is flush with the shaft into a position radially protruding over the shaft, and a needle guide unit, which is provided on the shaft and in which at least one needle (8, 9) arranged movably along the shaft is guided, which needle can be reversibly transferred from a retracted position into an advanced distal position, in which the needle penetrates the means located in the position radially protruding over the shaft, wherein a suture (21) that is carried along by the means remains in the means by retracting the needle in the retracted position. The invention is characterized in that the means has limbs (19, 20) that can be radially expanded away from the shaft and are operatively connected to an element (17) such that the limbs can be reversibly transferred from the position that is flush with the shaft into the position radially protruding over the shaft. |
