1. Surgical instrument for removing a surgical clip applied to a hollow organ, said clip comprising two clamping arms having two free ends and two ends connected to each other and defining a connecting region, and said surgical instrument comprising:
a proximal and a distal end, a spreading device for grasping and spreading apart an applied clip from an applied position to a released position arranged at the distal end, the spreading device comprising a clip receptacle and at least one proximal clip receiving stop and at least one distal clip receiving stop which respectively delimit the clip receptacle at a proximal side and at a distal side, wherein: the spreading device is transferable from an insertion position in which the spreading device defines a minimal cross-sectional area to a clip receiving position in which the clip receptacle is open to receive the clip to be removed, and a spacing in a longitudinal direction between the at least one proximal clip receiving stop and the at least one distal clip receiving stop decreases during transfer of the spreading device from the clip receiving position to a clip spreading position.
