  • Patent number: 11103229
    Abstract: Methods and apparatus for performing joint laxity measurement are disclosed. A retractor includes a plurality of spacers, such as plates, that are capable of being moved from a central portion of the retractor by a carriage mechanism. In some cases, the carriage mechanism may press against ramps connected to internal sides of the plates, thereby causing the plates to be displaced outwardly. In other cases, the carriage mechanism may include blades that rotate and press against the internal sides of the plates, thereby causing the plates to be displaced outwardly. The retractor is mounted on a surgical device configured to actuate the carriage mechanism. When the retractor is placed in a joint and the carriage mechanism is actuated, a measurement of the joint laxity may be determined based upon characteristics of the retractor and/or the surgical device.
