Abstract: Materials and methods for producing tactile anatomical structures are described. These are intended primarily for use for high-value, in-depth surgical training for novice or expert surgeons. They may also be used for medical education, sales demonstrations, or for research and development. Examples of embodiments refer to their use in knee and shoulder models. The tactile tissue-simulating structures include, amongst others: skin, fat, muscles, ligaments, tendons, cartilage, bursa, fat pad, and periosteum. A method for creating a musculotendinous junction is also described.

Abstract: A system for orthopaedic surgery training is provided, the system comprising an apparatus for supporting at least one artificial model of a human joint releasably mounted to the apparatus. The system may further comprise at least one artificial model of a human joint for mounting to the apparatus, wherein the joint may comprise a shoulder.

Abstract: In at least one aspect of this disclosure, a surgical drill can include a housing, a retracting enclosure slidably disposed within the housing and configured to move between an extended position and a retracted position and a retracting motor operatively connected to the retracting enclosure to move the retracting enclosure between the extended position and the retracted position. The drill can further include a drill motor including a motor shaft configured to connect to a drill chuck and disposed within the retracting enclosure such that the motor shaft can rotate relative to the retracting enclosure.

Abstract: A resistance device includes an impeller rotatably mounted on an impeller shaft and housed in an impeller housing, the impeller configured to act on an working fluid, a one-way drive assembly connected to the impeller shaft and configured to drive the impeller in one direction, the one-way drive assembly including a driving shaft connected thereto, a variable moment arm drive operatively connected to the driving shaft and configured to modify a distance between the driving shaft and a cable force vector applied to the variable moment arm drive, the variable moment arm drive including a cable connection portion, and a cable connected to the cable connection portion of the variable moment arm drive via a return spring, the cable configured to be pulled by a user.

Abstract: Instrumentation for an open or arthroscopic Latarjet procedure that allows more control graft handling during the formation of the hole and proper positioning parallel to the articulating bone surface. The surgical instrumentation of the present invention includes an osteotome with a plurality of markings and a depth stop, a drill guide with jaws configured to securely engage an outer surface of the graft, and an offset guide to position the graft to the bone.
