Fixing system and aligning device
A fixing system for an aligning device of a tibial resection guide for fixating attachment to a limb and an aligning device having the fixing system. The fixing system includes a carrier device having an attachment portion for attaching to an adjustment rod, a fixing magnet arranged on a front side of the carrier device, and a magnetic band adapted to be attracted to the fixing magnet and adapted to be attached to the limb of a patient.
1. A fixing system for an aligning device of a tibial resection guide for fixating attachment to a limb of a patient, the fixing system comprising:
a carrier device having an attachment portion for attaching to an adjustment rod;
a fixing magnet arranged on a face side of the carrier device; and
a magnetic band comprising a first side adapted to be attracted to the fixing magnet and a second side opposite the first side, the second side having a concave curvature adapted to be attached to the limb of the patient.
2. The fixing system according to claim 1 , wherein the magnetic band comprises a magnetic slap wrap having a longitudinal axis that extends along a straight line by a geometric restriction against a pretension in a first state, and that winds around the limb of the patient in a spiral or helical manner in a second state after the geometric restriction has been removed, relieving the pretension and clampingly fixing the magnetic slap wrap.
3. The fixing system according to claim 2 , wherein the magnetic slap wrap has a length of at least 300 mm along its longitudinal axis.
4. The fixing system according to claim 1 , wherein the magnetic band comprises a magnetic foil, the magnetic foil having a back that has an adhesive portion to be adhered to a body part.
5. The fixing system according to claim 1 , wherein the magnetic band comprises a magnetic wristband with a closure, the magnetic wristband being attachable in a wrapping manner to the limb of the patient and configured to be closed and fixed by the closure.
6. The fixing system according to claim 1 , wherein the carrier device has a carrier base with the attachment portion and a slider with the fixing magnet, wherein the slider is displaceable translationally in a sliding direction relative to the carrier base.
7. The fixing system according to claim 6 , wherein the carrier device has a rotational adjustment mechanism with which the position of the slider relative to the carrier base is adjustable in the sliding direction.
8. The fixing system according to claim 1 , wherein the carrier device has a concave holder perpendicular to a longitudinal axis of the attachment portion, in which the fixing magnet is enclosed, so that in addition to a force-fitting fixation, a form fit to sides of a tibial axis is achieved.
9. The fixing system according to claim 1 , wherein the attachment portion comprises a cantilever having a passage slit along its longitudinal axis for displaceably accommodating an adjustment rod in a direction of the longitudinal axis.
10. An aligning device for a tibial resection guide having an adjustment rod configured to be arranged at a patient's tibia and having a guiding device at a proximal end of the adjustment rod for guiding a tool during a resection of the patient's tibia, the aligning device comprising a fixing system according to claim 1 arranged at a distal end of the adjustment rod or towards the distal end of the adjustment rod.
11. A fixing system for an aligning device of a tibial resection guide for fixating attachment to limbs, the fixing system comprising:
a carrier device having an attachment portion for attaching to an adjustment rod;
a fixing magnet arranged on a face side of the carrier device; and
a magnetic band adapted to be attracted to the fixing magnet and adapted to be attached to limbs of a patient,
wherein the magnetic band comprises a magnetic foil, the magnetic foil comprising a back having an adhesive portion to be adhered to a body part.
12. The fixing system according to claim 11 , wherein the carrier device has a carrier base with the attachment portion and a slider with the fixing magnet, wherein the slider is displaceable translationally in a sliding direction relative to the carrier base.
13. The fixing system according to claim 12 , wherein the carrier device has a rotational adjustment mechanism with which the position of the slider relative to the carrier base is adjustable in the sliding direction.
14. The fixing system according to claim 11 , wherein the carrier device has a concave holder perpendicular to a longitudinal axis of the attachment portion, in which the fixing magnet is enclosed, so that in addition to a force-fitting fixation, a form fit to sides of a tibial axis is achieved.
