BONE FRACTURE RESETTING METHOD AND PARALLEL-CONNECTION EXTERNAL FIXING BRACKET USED FOR BONE FRACTURE RESETTING

摘要

A bone fracture resetting method and a parallel-connection external fixing bracket used for bone fracture resetting, the bone fracture resetting method being used for existing six branch link annular parallel-connection orthopaedic external fixing brackets, comprising the main steps: mounting the external fixing bracket, performing medical imaging scanning and three-dimensional image re-construction, identifying attitude information, interactive planning of the resetting motion, solving the external fixing bracket adjustment plan, and adjusting the external fixing bracket. The external fixing bracket is composed of two fixing rings (101, 102), six adjustable branch links (103, 104, 105, 106, 107, 108), and six markers (601, 602, 603, 604, 605, 606), the fixing rings (101, 102) being provided with a plurality of connecting holes (401, 402, 403, 404, 405, 406, 407, 408, 409, 410, 411, 412), the branch links (103, 104, 105, 106, 107, 108) being provided with a ball hinge (1301), a lockable drive joint (1302), a quick detachment structure (1303), and a Hooke hinge (1304), and the markers (601, 602, 603, 604, 605, 606) being composed of marker balls (701, 803, 804, 805, 806, 807, 808) and a pin shaft (702). Using the present bone fracture resetting method can accurately and intuitively treat bone fractures or bone deformities in a minimally invasive manner and when combined with the present bracket, can further increase the accuracy, reliability, and ease of operation of treatment.
