摘要： An echo tracking processor unit detects a bone surface section based on an echo signal and tracks a position of the bone surface section. An interpolation line generator unit generates an interpolation line connecting tracking points which represent the tracked bone surface section. A translational displacement corrector unit removes a translational displacement component between an interpolation line corresponding to a time phase of a no-load state stored in a memory and an interpolation line corresponding to a time phase in a loaded state output from the interpolation line generator unit. A strain calculator unit calculates an amount of strain of bone for each time phase and outputs to a characteristic curve generator unit. The characteristic curve generator unit generates a characteristic curve related to the strain of bone based on a load value output from a load measurement device and the amount of strain of bone output from the strain calculator unit.

摘要： An external skeletal fixation device reduces load on the patient, is capable of freely moving and deformity correction of a bone and bone fragments, is simple in construction and can be attached to the patient by an operator who has not a very high skill and long experience. An external skeletal fixation device 1 includes a pair of pin clamp units 2 and 3 fixedly holding rodlike members 61 and 62 inserted, respectively, into a first part 9B2 and a second part 9B3 of a bone 9B on the opposite sides, respectively, of a virtual hinge point 9B1 in the bone 9B. The virtual hinge point corresponds to a center of rotational angulation of the bone, a center on which the first and the second part of the bone respectively on the opposite sides of a fracture site of the bone or a part of the osteotomy site for deformity correction are turned, or a center about which a joint turns. A connecting mechanism 4 connecting the pair of pin clamp units 2 and 3 has a pair of arms 41 and 42 pivotally connected to the pair of pin clamp units 2 and 3, respectively. The pair of arms 41 and 42 are pivotally joined together. The respective axes A1, B1 and C1 of rotary joints A, B and C respectively connecting the pin clamp units 2 and the arm 41, the pin clamp unit 3 and the arm 42, and the arms 41 and 42 extend toward the virtual hinge point 9B1.
