Abstract
The invention discloses a fracture block fixing traction and tracking device for a navigation system. The device comprises a fracture block fixing portion, an operation portion and a tracking portion. The fracture block fixing portion is cylindrical and comprises a first end face and a second end face. The first end face is of an annular tooth-shaped structure. A counterbore structure is formed in the center of the annular tooth-shaped structure. A circular hole is formed in the center of the counterbore structure. The operation portion comprises a holding rod, a connecting rod and a sleeve. One end of the connecting rod is fixedly connected to the middle of the holding rod. The other end of the connecting rod is connected with the sleeve. The fracture block fixing portion is sleeved with the sleeve and fixed to the axis of the fracture block fixing portion through a nut and can rotate along the peripheral line of the fracture block fixing portion. The tracking portion comprises a support and an infrared reflecting light ball array installed on the support. Due to the rotatable operation portion, influences on surgical operation can be reduced; in the surgical process, repeated disassembly and assembly can be performed, and original navigation precision can be kept with no re-rectification.
