Electric motor driven tool for orthopedic impacting
An orthopedic impacting tool comprises a motor, an energy storage chamber, a striker, and an anvil. The motor stores energy in the energy storage chamber and then releases it, causing the striker to apply a controlled force on an adapter to create a precise impact for use in a surgical setting. The tool may further comprise a combination anvil and adapter. The tool further allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of a broach, implant, or other surgical implement from the opening. An energy adjustment control of the tool allows a surgeon to increase or decrease the impact energy. A light source and hand grips improve ease of operation of the tool.
Pneumatic surgical instrument and corresponding methods for implanting, extracting and reorienting orthopedic implants
Various embodiments of components, devices, systems and methods are provided for a pneumatic surgical instrument having a probe or an impactor disposed at a distal end thereof and configured to make contact with a selected portion of an orthopedic implant or device. The instrument is configured to generate a shock wave, which is then transferred to the distal end of the probe or impactor, and thence into the orthopedic implant or probe.
Bone fixation tool
Various embodiments of the present disclosure include a tool for stabilizing a fractured bone. The tool comprises a barrel having a proximal end and a distal end. The distal end of the barrel includes a passageway for receiving a bone pin configured to be driven into the fractured bone to stabilize the fractured bone. The passageway is sized to accommodate axial movement of the bone pin through the passageway while limiting radial movement of the bone pin in the passageway. The tool further comprises a piston having a proximal end and a distal end and configured to translate axially relative to the barrel. The proximal end of the piston includes a head and the distal end of the piston includes a needle formation, the needle formation being sized for receipt within the passageway of the barrel to drive the bone pin axially from the barrel and into the fractured bone.
MULTI-USE TOOL
Apparatuses and systems including an instrument for manipulating components within a knee joint of a patient are disclosed. Such manipulation can include inserting and/or removing such components to or from a bone of the knee joint. The instrument can include a handle, a body, a plunger, a detent and a collar. The handle can have a proximal end and a distal end and a longitudinal extent between the proximal end and the distal end. The body can be coupled to the handle and can extend distal of the distal end. The body can define a receptacle therein having an opening at a distal end portion of the instrument. The plunger can be moveably disposed within the body and can be moveable between a first position and a second position. The detent can be moveable by the plunger, such that with the plunger in the first position at least a portion of the detent can extend into the receptacle and with the plunger in the second position the detent can be recessed from the receptacle. The collar can be disposed about at least a portion of the body and can be moveable relative to the body to operatively actuate the plunger from the first position to the second position.
ORTHOPEDIC ADAPTER FOR AN ELECTRIC IMPACTING TOOL
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 and remover devices
An impactor having a housing including an upper portion and a lower portion at least a part of which extends perpendicularly from the upper portion, a ram having a first end positioned in the upper portion and positioned in axial alignment with the lower portion, an opposite end of the ram extending from the lower portion of the housing, at least one drive assembly including a first drive shaft operably coupled to a cam shaft, a cam operably coupled to the cam shaft, a cam operably coupled to the cam shaft, the drive shaft operably connectable to motor, wherein the cam is operable to rotate and positioned to contact the proximal end of the ram upon rotation of the cam, a circuit board comprising circuitry operable to receive instructions from a plurality of switches electrically coupled to the circuit board to operate the impactor, wherein the impactor is operable to deliver low amplitude pulsed strikes to a workpiece at variable frequencies.
ORTHOPEDIC IMPACTING DEVICE HAVING A LAUNCHED MASS DELIVERING A CONTROLLED, REPEATABLE & REVERSIBLE IMPACTING FORCE
A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.

Device for driving fixation elements into bone and method of use thereof
A implanting device for driving a fastener or fixation element into bone is described. Also described are methods for using a implanting device for driving a fastener or fixation element into bone and a kit comprising a pneumatic implanting device for driving a fastener or fixation element into bone.
ORTHOPEDIC SURGICAL INSTRUMENT
An orthopedic surgical instrument or impactor arranged and configured to convert rotational motion of a motor into linear (e.g., reciprocating) motion of an internal hammer to drive an orthopedic implant (e.g., an acetabular cup, a femoral hip implant, an intramedullary nail, etc.) and/or a surgical tool (e.g., a broach, a rasp, a cutting tool, etc.) into a patient's bone. In addition, and/or alternatively, the orthopedic surgical instrument may be reversed to assist with removal of the orthopedical implant and/or surgical tool. In some examples, the orthopedic surgical instrument includes a swashplate and a wobble shaft to convert the rotational motion into linear motion. In addition, and/or alternatively, the orthopedic surgical instrument may be arranged and configured with multiple modes of operation to enable a user to selectively, and independently, adjust the impact energy, frequency, etc.
