Abstract

A medical shaft instrument includes an instrument head with at least one jaw member for applying clamps with two jaw member branches. The instrument head is connectable over an instrument shaft having an outer tube with a handle for actuation of the jaw member. A clip magazine includes a retaining rail for supporting clamps in a predetermined storage position distance from each other. All the clamps are advanceable by a forth and back movable conveying and advancing rail. The clamp closest to the instrument head is conveyable by a tongue into the jaw member between the jaw member branches. The retaining rail has a distally extending support plate or bridge, which covers a jaw member region of a jaw member branch on the other jaw member branch facing side such that a tipping of an advanced or advanceable clamp on the jaw member branch is prevented.
