PROBLEM TO BE SOLVED: To provide an instrument for artificial knee joint replacement surgery, with which the position of a desired site inside a patient body can easily be specified.SOLUTION: The instrument for artificial knee joint replacement surgery comprises: a holding mechanism 2 which includes a holding part 4 having contact parts 6 to be brought into contact with contact objects of a patient undergoing artificial knee joint replacement surgery, and which is held against the patient while the contact parts 6 are in contact with the contact objects; and an indicating mechanism 3 comprising a positional specification requiring object indicating part 18, which is attached to the holding mechanism 2 and is to be arranged in a position corresponding to the positional specification requiring object, or the site in the patient of which position needs to be specified with the holding mechanism 2 held against the patient. The position where the positional specification requiring object indicating part 18 is arranged is decided on the basis of the preoperatively determined positional relationship between the contact objects and the positional specification requiring object.SELECTED DRAWING: Figure 1 |
