Abstract

In order to make it possible, in a surgical instrument comprising a tubular shaft with two tools pivotable towards one another at its distal end, these tools being pivotable relative to one another by means of a grip section at the proximal end of the tubular shaft via a transfer member arranged in the tubular shaft, to use the tools in a region arranged laterally of the instrument even with a simple construction it is suggested that the pivot axis of the tools extend concentrically to the longitudinal axis of the tubular shaft, that one tool be securely connected to the tubular shaft and the other securely connected to the transfer member, that the transfer member be a core mounted in the tubular shaft for rotation about its longitudinal axis, and that the grip section comprise two grip elements pivotable towards one another, one of these elements being connected to the tubular shaft and the other to the transfer member.

A surgical instrument comprising:

a tubular shaft, and two tools pivotable towards one another at a distal end of the shaft,
said tools being pivotable relative to one another by means of a grip section at a proximal end of the tubular shaft via a transfer member arranged in the tubular shaft, wherein:
the pivot axis of the tools extends concentrically to a longitudinal axis of the tubular shaft,
one of the tools is securely connected to the tubular shaft and the other of the tools is securely connected to the transfer member,
the transfer member comprises a core mounted in the tubular shaft for rotation about the longitudinal axis,
the grip section comprises two grip elements pivotable towards one another about a pivot axis, that extends concentrically to the longitudinal axis of the tubular shaft,
one of the grip elements is securely connected to the tubular shaft and the other of the grip elements is securely connected to the core, and
each of the grip elements has a gripping area extending parallel and laterally offset in relation to the longitudinal axis of the tubular shaft.
