DEVICE AND METHOD OF AUTOMATIC CALIBRATION OF A TENSOR IN ARTHROPLASTY PROCEDURES |
摘要 |
The present invention relates to a computer assisted surgical navigation method for determining the patient-specific pressure that must be applied on one or both sides of a joint during the ligament balancing steps of an arthroplasty procedure, said method comprising: inserting a tensor (22) inside the joint between a first bone (8) and a second bone (2) when the joint is in a given angular orientation; controlling the pressure applied by the tensor (22) to the joint so as to make it increase from a minimum value to a maximum value; measuring the evolution of the distance between the first and the second bones during said pressure increase; determining the relationship between said distance and said pressure; processing said relationship to determine said patient-specific pressure to apply to the joint. |
