APPLIANCE FOR KYPHOPLASTY AND METHOD FOR KYPHOPLASTY Russian patent published in 2007 - IPC A61B17/70 A61B17/02 

FIELD: medicine, traumatology, orthopedics.

SUBSTANCE: the suggested appliance for kyphoplasty has got a handle and a tube. The tube is coaxially connected with the handle and ends blindly, its diameter of external surface is up to 5 mm and it has a decentralized internal canal. The latter has a curvature at the angle of about 30-45°. In the tube's distal end, at the opposite side against the internal canal a rectangular foramen is located. Inside the handle and the tube there is a mobile rod with small threading at its proximal end. The rod is screwed into the coupling. The latter is supplied with a handle for rotation. The rod's distal end is connected with a short rod by hinge. At the short rod's distal end there is a rectangular platform with possibility to be opened out, by size it corresponds to the rectangular foramen. While reconstructing the height of a vertebra's body due to developing a cavity and introduction of osseous cement intracavitarily one should fulfill the dosed opening out of the appliance's rectangular platform. This appliance should be introduced into the body of the broken vertebra through the developed canal fulfilled in the area of the pedicle. As a result, this appliance could be used once again. The method has been, also, elaborated in the course of which this appliance should be used.

EFFECT: higher efficiency.
