    摘要: The invention relates to a rotational position determination apparatus (15) for determining an entry rotational position, which defines a rotational position of an insertion device like a stent at an entry site (5), such that a navigation of the insertion device from the entry site to a target site (6) along an inner path (8) results in a rotational position of the insertion device at the target site being equal to a desired target rotational position based on a representation of the inner path and the desired target rotational position. If the insertion device is arranged in the determined entry rotational position at the entry site and then navigated to the target site, it is therefore not necessary to rotate the insertion device at the target site, i.e. it is not necessary to use a technically complex interventional device for rotating the insertion device at the target site.

    摘要: A surgical cutting instrument including a first tubular member, a second tubular member, a sleeve member, a third tubular member, and an orientation member. A distal section of the first tubular member includes a cutting tip. The distal region of the second tubular member forms a cutting window. The first elongated member is co-axially disposed within the second tubular member such that the cutting tip is selectively exposed at the cutting window. The first and second tubular members are co-axially disposed within the sleeve member. The third tubular member is co-axially disposed around the intermediate section of the first tubular member, the intermediate region of the second tubular member and the sleeve member. The orientation member is rotatable to transmit a rotational force applied to the orientation member to selectively rotate the second and third tubular members relative to the sleeve to effectuate spatial rotation of the cutting window.
