  • Surgical tool handle assemblies and related methods
    Patent number: 10667798
    Abstract: A surgical tool handle assembly can include a handle body and a tool locking mechanism. The handle body can have a tool receiving end for receiving a mating end of a surgical tool. The tool locking mechanism can be configured to securely engage the surgical tool mating end, thereby locking the surgical tool to the handle. The locking mechanism can include a ramp feature, a locking cam, and an actuation mechanism. The actuation mechanism can be configured to actuate the cam to engage the ramp feature as the cam engages the tool mating end to lock the tool to the handle. A surgical kit and a method of locking a surgical tool to a tool handle are also disclosed.

  • Modular screw apparatus and method
    Patent number: 9204978
    Abstract: An orthopedic instrument comprises a shell configured to be inserted into a cup-shaped site, a liner configured to be received within a cavity of the shell, wherein the liner has an aperture and a mating feature adjacent to the aperture, and a modular screw configured to be received within the aperture of the liner. The modular screw can include a first component that is positionable adjacent to a first side of the mating feature and a second component that is positionable adjacent to a second side of the mating feature. When assembled, the modular screw can be configured to rotate relative to the liner.
