Title:
伸縮型のＩＭネイルならびに駆動機構
Document Type and Number:
Japanese Patent JP6606043
Kind Code:
B2
Abstract:
A length-adjustable IM nail system includes a telescoping IM nail with proximal and distal bodies. An inner magnet within the proximal body is connected to a threaded rod which, in turn, is connected to the distal body. The threaded rod passes through a threaded block which is connected to the proximal body. The position of the distal end of the threaded rod is fixed with respect to the distal body, but may rotate freely within this fixed position. An actuator is also disclosed that includes a pair of rotating magnets disposed in an angular relationship with each other and the axis of the IM nail and the patient's limb. Rotation of these outer magnets in the same direction results in rotation of the inner magnet and threaded rod and a telescoping axial movement of the threaded block and proximal body with respect to the distal body.
