APPARATUS FOR VERTEBRA BALLOON KYPHOPLASTY Russian patent published in 2011 - IPC A61B17/70 A61F2/44 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, in particular to instruments for traumatology, neurosurgery, vertebrology, and can be used for reconstruction of vertebra in process of performing surgery by technology of balloon kyphoplasty. Apparatus contains device for pumping bone-substituting material into vertebra body, bearing catheter tube with canal for pumping liquid under pressure into hermetically fixed in distal end of bearing catheter tube dilatation balloon from elastic stretchable material with located above it proportionate protective envelope, provided with fixers. Protective envelope is made proportionate to dilatation balloon from medical material, with cells, formed by crossing threads. Protective envelope does not let through particles of bone-substituting material and does not prevent flows of form elements of blood from passing through injured vertebra. Fixers are made in form of elongated elements from metal, fixed in places of threads crossing or are interweaved into protective envelope, and which protrude outwards from protective envelope with possibility of penetration into bone tissue.

EFFECT: invention ensures stable position of straightened and restored by means of dilatation balloon vertebra body, including position at the moment of balloon blowing out before pumping bone-substituting material.
