METHOD OF ANCHOR FIXATION OF BONE FRAGMENTS WITH APPLICATION OF STRING AND ANCHOR Russian patent published in 2011 - IPC A61B17/60 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Method of anchor fixation of bone fragments with application of string is characterised by the following: applied string is made of metal with shape memory, at least, two anchor devices are reversely wedged in fragments, connected with elastic arch and tightened with string from metal with shape memory. Anchor device contains shank, core, lock, bush and compensator. Shank is made in form of tube with levers, neck and intraosteal leg. Levers have holes for screws for fixation of elastic arch. Intraosteal leg has thread and longitudinal cuts in which lugs are located on axes. Lugs are connected with spring and are installed movably. Core is installed in shank coaxially. Lock has thread connection with shank neck with possibility of rotation and ensures core travel along shank axis and fixes core position along shank axis. Core travel ensures lug rotation around axis with movement of lug from shank opening and picking up bone fragment with lug. During core lifting spring tension performs return of lug into shank opening. Bush has bed for string and has possibility of threading, lowering along leg and resting with its base on bone fragment. Compensator ensures transmission of rotation effort to lock toward threading.

EFFECT: inventions ensure increase of efficiency of rehabilitation of patients with violation of facial skeleton integrity of various genesis by improvement techniques of fixation application.
