Orthopedic adapter for an electric impacting tool
12440256 · 2025-10-14 · ·

An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy. The adapter can connect to the surgical implement and to the orthopedic impactor without the use of external tools. The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.

IMPACTOR DESIGN FOR BIDIRECTIONAL IMPACT FORCE

An impactor and methods of operation of an impactor. The impactor includes an electromagnetic component having a stationary electromagnetic housing and a moving armature component. The housing includes a coil that receives an electric current resulting in generation of an electromagnetic field for triggering translation of the armature within the housing. The impactor includes a striker body coupled to the armature. The striker body includes a distal end. The impactor includes a strike chamber having an interior and a distal strike wall disposed at a distal end of the chamber, and a spacer disposed at a proximal end of the chamber and opposite the distal strike wall. The electromagnetic field forces the armature and the striker body to translate in at least one direction. Translation of the armature causes the distal end of the striker body to strike at least one of the distal strike wall and the spacer.

Hand piece for powered osteotome

Provided is an osteotome handpiece that may be driven by compressed gas. In an embodiment, a spherical piston may be movable inside a cylinder having a liner, which may be made of a low-friction material such as a fluoropolymer. The spherical piston may impact a blade holder that transmits force to a blade. A piston return spring may be provided, along with a piston washer to avoid any possible outward deformation of the spring. The blade holder may be retained by a split and threaded retaining collar. Single-stroke or multi-stroke operation may be chosen by the user. The device has long-operating low-maintenance advantages.

Handheld surgical instrument

A handheld surgical instrument comprising an energy storage element, wherein the energy storage element is a spring coupled to the impacting mechanism, an impacting mechanism has a tip configured to impact a bone, wherein the tip includes a tapered point, a power transmission mechanism is configured to transmit energy from the energy storage element to the impacting mechanism, wherein the power transmission mechanism includes a semi-flexible metal wire guided by a hollow shaft, wherein the hollow shaft includes a distal end, the semi-flexible metal wire is includes a bend toward the distal end, a trigger mechanism is configured to release energy from the energy storage element, wherein the bend includes an angle between 14 degrees and 46 degrees, wherein the trigger mechanism includes a manual lever which, when actuated, simultaneously retracts the tip and charges the energy storage element.
