Abstract: A locking adapter configured to removably attach a surgical tool to a surgical handpiece unit can include a first coupling portion having a first hole and a second coupling portion having a second hole. The first and second holes can receive a portion of a surgical instrument, such as a cutting element (e.g., a burr or blade). The locking adapter can have a first position where the first hole is not aligned with the second hole and a second position where the first hole is aligned with the second hole. When the locking adapter is in the second position and the portion of the surgical instrument is received within the first and second holes, the first coupling portion can apply a first force on the portion and the second coupling portion can apply a second force on the portion, the first and second forces having different directions.

Abstract: Various articulating tools for endoscopic placement of fasteners are disclosed. The tool can comprise a multi-angle articulating screwdriver. The tool can have an elongate shaft with an articulating driver head at a distal end. The tool can rotate the articulating driver head to drive fasteners, such as screws, to a surgical site. The articulating driver head can articulate with respect to a longitudinal axis of the elongate shaft to enable the fastener to be driven at various angle. The tool can be coupled to a powered handpiece power and can transmit torque from the handpiece to the driver head.

Abstract: Various torque-limiting screwdriver devices, systems, and methods are disclosed. The screwdriver can include a body, a motor that is configured to rotate a screw engaged with the screwdriver, and a processor configured to control operation of the screwdriver. The screwdriver can have torque-limiting functionality, such as by monitoring the amount of torque applied to the screw and reducing or stopping rotation of the screw when certain torque-limiting criteria are met. In some embodiments, the screwdriver can be switched between manual operation by a user, and automated operation by a motor within the screwdriver. In some embodiments, the screwdriver can be attached to a robotic arm.

Abstract: Various torque-limiting surgical driver devices, systems, and methods are disclosed. The surgical driver can include a body, a motor that is configured to rotate a drill bit engaged with the surgical driver, and a processor configured to control operation of the surgical driver. The surgical driver can have torque-limiting functionality, such as by monitoring the amount of torque applied to a drill bit and reducing or stopping rotation of the drill bit when certain torque-limiting criteria are met.
