Abstract
A tool, consisting of an enclosure and a rotatable knob retained by, and protruding from, the enclosure. The tool has a tube having a proximal end that is retained by the enclosure, and the tube has an axis of symmetry. A Geneva drive is retained within the enclosure, the Geneva drive consisting of a drive wheel fixedly attached to the rotatable knob and a driven wheel fixedly attached to the proximal end of the tube, so that an axis of rotation of the driven wheel coincides with the axis of symmetry of the tube. Thus, a continuous rotation of the rotatable knob causes the tube to rotate about the axis of symmetry in discrete angular steps.
Claims7
A balloon sinuplasty tool, comprising:
- an enclosure;
- a rotatable knob retained by, and protruding from, the enclosure;
- a tube having a proximal end retained by the enclosure, the tube having an axis of symmetry;
- a guidewire insertion tube configured to guide a guide wire therethrough and hold a balloon thereon,
- a balloon insertion mechanism;
- and
- a Geneva drive retained within the enclosure, the Geneva drive comprising a drive wheel fixedly attached to the rotatable knob and a driven wheel fixedly attached to the proximal end of the tube, so that an axis of rotation of the driven wheel coincides with the axis of symmetry of the tube,
- whereby a continuous rotation of the rotatable knob causes the tube to rotate about the axis of symmetry in discrete angular steps.
A method, comprising:
- providing an enclosure;
- positioning a rotatable knob to be retained by, and protrude from, the enclosure;
- positioning a tube having a proximal end to be retained by the enclosure, the tube having an axis of symmetry;
- positioning a guidewire insertion tube, wherein the guidewire insertion tube is configured for guiding a guide wire therethrough and holding a balloon thereon,
- positioning a balloon insertion mechanism;
- and
- positioning a Geneva drive to be retained within the enclosure, the Geneva drive comprising a drive wheel fixedly attached to the rotatable knob and a driven wheel fixedly attached to the proximal end of the tube, so that an axis of rotation of the driven wheel coincides with the axis of symmetry of the tube,
- whereby a continuous rotation of the rotatable knob causes the tube to rotate about the axis of symmetry in discrete angular steps.
