MEDICAL SHAFT-TYPE INSTRUMENT WITH A SUPPORT PLATE/BRIDGE ON THE RETAINING RAIL

摘要

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.

主权项

1. A medical shaft instrument, comprising:
an instrument head having at least one jaw member for applying clamps with two scissor-like movable jaw member branches, the instrument head connectable with an instrument handle via an instrument shaft having an outer tube for actuating the at least one jaw member; and a clip magazine in which a retaining rail is fixed for supporting clamps in a predetermined storage position distance from each other according to a “single-storage-principle”, wherein all the clamps are advanceable respectively by one storage position in a direction towards a distal end of the instrument shaft by a back and forth movable conveying and advancing rail in a single conveying stroke, one of said clamps that is closest to the instrument head being conveyable into the at least one jaw member between the jaw member branches, the retaining rail comprising a support plate or bridge extending into a distal direction, which covers a jaw member area in a region of one of the jaw member branches on the side thereof, facing the other of the jaw member branches such that a tipping of an advanced or advanceable clamp on said one of the jaw member branches is prevented.
