The present invention relates to a pneumatic impact tool for hip surgery, comprising a housing with a cylinder/piston assembly with a pneumatically driven piston and a tool holder. The impact tool has two or more handles which are arranged at regular intervals around the cylinder/piston assembly.

Disclosed herein are orthopedic impact tools and methods of use thereof. The orthopedic impact tools can include a housing, a tube assembly, a reverse impact plate, an anvil and an impact mechanism. The housing can include a hand grip portion and an impact mechanism housing portion. The tube assembly can include a first tube portion and a second tube portion. The reverse impact plate can be disposed in between the first tube portion and the second tube portion. The anvil can include a forward impact surface. The impact mechanism can include a motor, a piston, a ram, and a rotary to linear conversion mechanism drivingly connecting the motor to the piston. The piston can be disposed within the first tube portion and the ram can be disposed in the second tube portion and movable into contact between the reverse impact plate and the forward impact surface.

Disclosed herein are surgical impact tools and methods of use thereof. The surgical impact tools can include a roller assembly, an impact structure, and a tool holder. The roller assembly can be connected to a motor and include a plurality of rollers supported by a respective roller arm. The impact structure can define a spring and an impact cavity including forward and reverse impact surfaces. The impact structure can include a wall comprising a plurality of thread elements connected to the wall and engageable with the roller assembly. Each of the thread elements can include a pair of helical end surfaces and a pair of axially extending surfaces that are engaged by the plurality of rollers. During use rotation of the roller assembly against the helical ends of the thread elements can cause axial movement of the impact structure to apply a load on the spring and generate impact forces.

Various exemplary gas spring surgical impacting tools and methods of using gas spring surgical impacting tools are provided. In general, a surgical impacting tool includes a gas spring assembly. The gas spring assembly includes a sealed chamber configured to contained compressed gas therein. The surgical impacting tool also includes a motor configured to cause compression of the gas in the sealed chamber. The compression and decompression of the gas is configured to drive movement of a surgical implement attached to the surgical impacting tool and configured to impact bone.

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.

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.

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.

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.

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.
