Abstract
A positioning apparatus is provided that is configured to perform a biopsy or therapy support by puncture using a needle or other needle-shaped equipment. This positioning apparatus is exemplified by an apparatus that includes a first rotation member, a guide for guiding a needle or other needle-shaped equipment in a longitudinal direction, a second rotation member with a different rotation axis, and a friction applying unit configured to apply friction force to the first rotation member directly or indirectly and generates friction torque.
Claims23
A positioning apparatus comprising:
- a first rotation member having a first rotation flexibility;
- a guide configured to guide needle-shaped medical equipment;
- a second rotation member, which is connected to the first rotation member, including the guide, and having a second rotation flexibility, of which the rotation axis is not parallel to the rotation axis of the first rotation member;
- and
- a friction applying unit configured to apply friction force to the first rotation member directly or indirectly for causing the first rotation member to generate a friction torque;
- wherein the friction applying unit applies friction force to the first rotation member directly or indirectly so that the first rotation flexibility of the friction torque of the first rotation member is greater than the first rotation flexibility of friction torque to be generated based on the rotation of the second rotation member.
