A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.

A surgical handpiece system for performing measurement functions and surgical operations. The system includes a handpiece assembly. The handpiece has a handpiece housing and a drive cannula rotatably coupled to the handpiece housing. The drive cannula extends along an axis and is configured to receive torque from a motor. A surgical attachment module has an attachment housing removably coupleable to the handpiece housing. The surgical attachment module has a drive shaft rotatably coupled to the surgical attachment housing and configured to receive torque from the drive cannula to operate an end effector. A measurement module has a measurement housing removably coupleable to the handpiece housing. The measurement module is configured to perform measurement functions associated with operation of the handpiece assembly.

Aspects of the present disclosure relate to systems for performing a surgical procedure using a power tool or power instrument with systems, devices and/or control units for adjusting, regulating, interrupting, and/or restoring electric current to the power tool or instrument during operation, for example, when the power tool or instrument is at a predetermined distance to a boundary of a safe zone or a target volume of operation.

Systems and methods for creating cuts on a bone are provided utilizing one or more cutting guides assembled to a plurality of bone pins, where the bone pins are inserted on the bone coincident with one or more virtual pin planes defined relative to one or more of the cuts. Alignment guides are also disclosed herein that aid in the creation of pilot holes for receiving a cutting block in a desired position and orientation (POSE). An articulating surgical device actively positions the bone pins coincident with the virtual plane to ensure the cutting guides, when assembled to the pins, aligns one or more guide slots in the desired POSE to create the cuts.

A rotary torque releaseor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil, The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to torque release the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary torque releaseor. High frequency axial movements by the torque releaseor obviate the need for a surgeon to provide an external push force on the torque releaseor in order to perform a successful surgical operation.

A method of evaluating a human knee joint which includes a femur bone, a tibia bone, a patella bone, a patellar tendon, and ligaments, wherein the ligaments and patellar tendon are under anatomical tension to connect the femur and tibia together, creating a load-bearing articulating joint, the method including: inserting into the knee joint a gap balancer that includes a tibial interface surface, an opposed femoral interface surface, and at least one force sensor, the method including: providing an electronic receiving device; moving the knee joint through at least a portion of its range of motion; while moving the knee joint, using the electronic receiving device to collect data from the at least one force sensor; processing the collected data to produce a digital geometric model of at least a portion of the knee joint; and storing the digital geometric model for further use.

A surgical system which may include a controller, a data entry device, a powered surgical handpiece and a surgical tool adapted to couple to the surgical handpiece. The surgical handpiece can include motor direction control and feedback, safety stop features, stimulation and nerve integrity monitoring, a tool connector assembly configured to retain a variety of surgical tools and optional navigation and/or electric ratcheting features.

A device for creating a cavity or a channel in bone. First and second steering cables are coupled to a flexible elbow or a tip of a shaft. A control assembly is operably coupled to the first and second steering cables and configured to tension one of the steering cables and slacken another one of the steering cables so as to flex the flexible elbow. The control assembly may include a steering block axially movable within a handle with a knob threadably coupled to the steering block. The steering block may be rotatably fixed within the handle. The first and second steering cables may be anchored to the steering block, such as to opposite sides of the steering block. The first steering cable may extend along a linear path, and the second steering cable may extend along a curved rib of the handle.

Cutting instruments and related methods are disclosed herein in which the diameter of the retrograde cutting blade can be adjusted to any of a plurality of diameter settings, allowing the same instrument to be used to form holes of different diameters. The limit diameter can be preset such that, during the cutting operation, the user need not be concerned with selecting the appropriate diameter, but rather can simply deploy the cutting blade until the preset limit is reached. Cutting instruments are also disclosed in which the retrograde cutting blade is distinct from the forward drilling tip and protected within a cavity formed in the body of the instrument when not in use, as are instruments in which the user is given visual and/or tactile feedback to confirm desired positioning of the cutting blade.
