A device for registering a bone for a robotic knee arthroplasty with a surgical robot can include a plate and a registration device. The plate can be engageable with the bone and can include a lateral portion, a medial portion, and a hinge. The registration device can be connected to the plate and can be configured to interface with the surgical robot for registration of the plate and the bone.

Instruments for robotic knee revision

An impactor tool can include a handle, an impactor, a lock, an actuator, and a pin. The impactor can be coupled to the handle. The lock can be extendable from the impactor to engage an implant and retractable into the impactor to secure the lock and the impactor to the implant. The actuator can protrude from the impactor and can be coupled to the lock. The actuator can include a cam defined by a channel extending through the actuator. The pin can be coupled to the lock and disposed within the cam channel, where the actuator can be operable along a path defined by the cam and the pin to extend and retract the lock.

Tibial tray impactor

Methods, techniques and apparatuses are disclosed including exemplary methods of performing a knee arthroplasty of the tibia. One exemplary method can include determining at least a depth of a distal fixation feature of a tibial implant, and forming a metaphyseal recess in a proximal portion of the tibia. The recess can be configured to receive the distal fixation feature therein and can be sized to exceed at least the depth of the distal fixation feature such that when a distal surface of the tibial implant contacts a proximal surface of the proximal portion of the tibia and the distal fixation feature is received in the metaphyseal recess, a gap remains between the distal fixation feature and one or more surfaces that form a portion of the metaphyseal recess.

Methods and techniques for tibial implant placement

A surgical instrument including a shaping instrument for shaping a bone as well as an impaction/extraction device for use with the shaping instrument is disclosed.

Surgical instrument for impacting and extracting a shaping instrument and a shaping instrument useable therewith

Orthopedic procedures can involve tools or other instruments that assist a surgeon. The surgical instrument including a cutting instrument configured to shape bone, including an impaction/extraction device, is disclosed. Methods of shaping a bone including the surgical instrument with the cutting instrument including an impaction/extract device are disclosed.

Surgical instrument for impacting and extracting a cutting instrument

A hydraulic brake booster system. The hydraulic brake booster system includes a primary piston axially moveable within a bore of a cylinder, a booster chamber located rearwardly of the primary piston within the bore, an input rod extending within the booster chamber, a booster vent path in selective fluid communication with the booster chamber, and a seal member located between the forward face and the primary piston, the seal member in a fixed relationship with the input rod and configured to (i) seal the booster vent path from the booster chamber when the input rod is in a first position, and (ii) not seal the booster vent path from the booster chamber when the input rod is moved rearwardly within the booster chamber to a second position.

Hydraulic booster vented input rod with poppet

A sealing member for a piston slidably disposed within the cylinder bore of a hydraulic system includes a seal body having an outer sealing surface arranged to contact the cylinder bore and a glide ring at least partially disposed within the outer sealing surface of the seal body. The glide ring includes an outer surface and the outer sealing surface of the seal body includes at least one seal lip projecting beyond the outer surface of the glide ring.

Seal member for a hydraulic braking system

A surgical instrument including a cutting instrument for shaping a bone as well as an impaction/extraction device for use with the cutting instrument is disclosed.

Guide pins for retaining a caliper in an anchor of a disc brake assembly. The guide pins are characterized by a cylindrical body having a first end and a second end with a first diameter section that extends from the first end separated by a shoulder from a second diameter section that extends from the second end. The cylindrical body has a threaded axial bore that extends from a face on the second end toward the first end. A bolt has a shaft with threads thereon which mate with the threaded axial bore in the cylindrical body. A bushing is concentrically located on the shaft and in a corresponding axial opening in an ear that extends from the anchor. Torque applied to the bolt acts on and brings the bushing into engagement with the face on the second end of the cylindrical body however as the bushing has a greater length than the width of the axial opening of the ear, a desired gap is developed between a head on the bolt, the second end and the ear. Because of the gap, the bolt may freely rotated in the axial opening when the torque is terminated to realign the cylindrical body in a bore in the support member and as a result axial movement of the caliper is not substantially inhibited during a brake application.
