Expansion device for bone expansion and medical device for bone expansion
View Patent ↗The invention relates to an expansion device for bone expansion, wherein the expansion device has a proximal end and a distal end, between which ends the expansion device extends in a longitudinal direction, and extending apparatuses, which succeed one another in the longitudinal direction, wherein the extension apparatuses can be extended in order to exert force on a bone.
1. A method comprising:
inserting an expansion device into a crevice of a bone, wherein the expansion device has a plurality of expansion chambers arranged along a longitudinal direction of the expansion device;
expanding the expansion chambers to exert a radial force on the bone;
controlling the expanding in accordance with the principle of callus distraction such that the expanding occurs over a plurality of days.
2. The method according to claim 1 , wherein the expanding comprises expanding the expansion chambers uniformly.
3. The method according to claim 1 , wherein the expanding comprises expanding the expansion chambers non-uniformly.
4. The method according to claim 1 , wherein the expanding comprises filling the expansion chambers with a liquid.
5. The method according to claim 1 , wherein the expanding comprises expanding the expansion chambers continuously over the plurality of days.
6. The method according to claim 1 , wherein the expanding comprises expanding the expansion chambers stepwise over the plurality of days.
