Abstract
The invention relates to a medical instrument, in particular an endoscopic instrument, with an instrument shaft, a tool positioned on the distal end of the instrument shaft, and a handle, which can be secured on the instrument shaft so that it can be moved in an axial extension of the instrument shaft. In order to create an instrument which makes possible a comfortable, safe, and reliable handling even with the most varied application purposes, it is proposed with the invention that the handle can be secured on the instrument shaft so that it can be moved by at least one degree of freedom with respect to the instrument shaft.
Claims20
An endoscopic medical instrument, comprising:
- an instrument shaft;
- a tool positioned on a distal end of the instrument shaft;
- a handle;
- and
- a coupling element securing the handle on the instrument shaft so that the handle can be moved by at least three degrees of freedom with respect to the instrument shaft, wherein one of the degrees of freedom is a translation movement in the direction of a longitudinal axis of the instrument shaft.
An endoscopic medical instrument, comprising:
- an instrument shaft;
- a tool positioned on a distal end of the instrument shaft;
- a handle;
- a coupling element securing the handle on the instrument shaft so that the handle can be moved by at least three degrees of freedom with respect to the instrument shaft;
- wherein a distal end of the handle is configured as a tensioning device to receive the coupling element;
- wherein a pressure force can be exerted on the coupling element by the tensioning device in such a way that the coupling element at least partially surrounds the instrument shaft while clamping said instrument shaft;
- and
- wherein the coupling element is configured as an essentially spherical component equipped with a penetration bore hole for the instrument shaft and the tensioning device of the handle is configured as a bearing for rotatable storage of the coupling element.
