Abstract: Instrument systems for performing total ankle arthroplasties comprise an instrument adapter, a talus reaming guide and a talar trial system. The instrument adapter comprises a coupler for attaching to a robotic surgical arm, an extension arm extending from the coupler, a talus resection block attached to the extension arm, including a talus cutting guide surface, and an interface for receiving another instrument. The talus reaming guide comprises a second attachment member for coupling to the interface, and a reaming hoop for confining movement of a reamer. The talar trial system comprises a talar adapter for connecting to the interface, and a talar trial couplable to the talar adapter, the talar trial including a talar bearing surface. The talus resection block can serve as a universal instrument adapter for mounting the talus reaming guide, the talar trial system and a tibia resection block for performing a total ankle arthroplasty.

Abstract: Techniques for securing an instrument to a surgical robot are provided. In an example, an apparatus can include a first portion, a second portion and a collar. The first portion can attach to an end of an arm of the surgical robot and can include a first rod extending away from the arm. The second portion can hold the surgical instrument and can include a second rod extending away from the surgical instrument. The collar can slidably adjust along an aligned axis of the first and second portions secure interfaces of the portions and to allow engagement and dis-engagement of the interfaces with each other.
