Abstract: The endoscopic instrument is formed as a needle holder with ligature scissors. It comprises at its distal end a jaw-like tool and at its proximal end a handle, these being connected to one another by a common shank. At the distal tool end there is formed the ligature holder and the ligature scissors proximally neighboring thereto. Between these tool parts there is formed a projection limiting the free passage between the needle holder and the ligature scissors, this projection being dimensioned such that although the ligature may be guided through, the needle however cannot get into the region of the scissors.

Abstract: The invention relates to a suction/rinsing instrument comprising a suction channel for removing fluid and a rinsing channel for supplying rinsing fluid. The suction channel is provided for receiving an auxiliary instrument. Via a grip part of the instrument, the auxiliary instrument, for example a forceps, may be controlled. The auxiliary instrument is fixed on the suction/rinsing instrument by way of a receiver. The receiver can be traversed in the axial direction of the shank, the traversing is effected via operating means provided on or near the grip part, so that the operator, without having to let go of the grip part, may selectively, with only one hand, push forward the auxiliary instrument an thus operate or also retract the auxiliary instrument and clear the suction/rinsing channel.
