Surgical screw extractor

Nail extractor

A handle for a surgical tool including a shaft having a proximal end and a distal end with a gripping handle affixed to the proximal end of the shaft. A bushing is attached to the distal end of the shaft, the bushing including a plurality of flexible members circumferentially spaced apart. The handle further includes a sleeve circumscribing the shaft and the bushing. The sleeve is moveable between a first position substantially covering an entirety of the bushing and a second position spaced from a most distal end of the bushing.

A cannulated nail extractor including an extractor having a proximal end for connecting to an extraction device, a distal end opposite the proximal end, and a connector extending from the distal end. The cannulated nail extractor further includes an engagement wire having an enlarged proximal end configured to engage the extractor and an enlarged distal end configured to engage a distal end of the cannulated nail. The cannulated nail extractor further includes a positioning wire for insertion into the cannulated nail for urging the enlarged distal end of the engagement wire into engagement with the distal end of the cannulated nail, whereby exerting an extraction force on the extractor produces extraction force by engagement of the enlarged distal end of the engagement wire on the distally facing end of the cannulated nail.

Drive handle

A knee prosthesis that includes a tibial component and femoral component. The tibial component includes an articular surface, a posterior portion and an anterior portion. The posterior portion includes a recess for receipt of a posterior cruciate ligament. The anterior portion includes a post extending therefrom. The post includes a posterior surface. The femoral component includes a condylar portion and an intercondylar portion. The intercondylar portion includes a posterior recess for receipt of the posterior cruciate ligament, a cam, and an engagement recess for receipt of the post. The cam includes a sliding surface and is disposed between the engagement recess and posterior recess. The sliding surface of the cam slides along the posterior surface of the post for restricting anterior subluxation of a femur bone when the articular surface and the condylar portion articulates through flexion of a knee joint.

Anterior stabilized PCL retaining total knee prosthesis

A bicruciate retaining tibial implant baseplate includes a tibial baseplate with medial and lateral condylar portions configured to receive bearing inserts. The baseplate includes an anterior bridge connecting the medial and lateral portions. A posterior wall of the anterior bridge may be angled to provide downward force on a correspondingly angled anterior portion of the tibial eminence when the baseplate is implanted. A method of preparing the tibia for implant includes a punch tower and punch guide configured to both cut the anterior tibial eminence and provide protection to the tibial eminence during resection of the proximal tibia.
