An orthopedic rotary tool may include a drive system including a first rotary component and a second rotary component, an energy storage element, an actuator system including a first actuator element disposed on the first rotary component and a second actuator element disposed on the second rotary component, a coupling mechanism, and an output element. The coupling mechanism may be operable between coupled states and decoupled states. During operation, the energy storage element may accumulate rotational energy via the drive system and relative rotation between the first rotary component and the second rotary component may cause interactions between the first actuator element and the second actuator element. The interactions may transition the coupling mechanism between the coupled states and the decoupled states. When the coupling mechanism is in the coupled states, the energy storage element may be configured to deliver a torque impulse to the output element.

Orthopedic rotary tool

In some implementations, an adjustable anvil assembly and/or a floating impact assembly may be used in an orthopedic impactor tool to provide linear impacts. The adjustable anvil assembly may include a rotatable anvil portion and a non-rotatable anvil portion. The rotatable anvil portion may be rotatable relative to the non-rotatable anvil portion. The floating impact assembly may include a linear motion converter that interfaces with a thrown mass of the orthopedic impactor tool via a floating coupling interface.

Anvil assembly and impact assembly for an orthopedic impactor 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.

A rotary torque releaseor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to torque release the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary torque releaseor. High frequency axial movements by the torque releaseor obviate the need for a surgeon to provide an external push force on the torque releaseor in order to perform a successful surgical operation.

Rotary tool with reduced recoil for orthopedic surgery

An orthopedic impactor tool may include a motor, a linear motion converter operatively coupled to the motor, a thrown mass operatively coupled to the linear motion converter, and an anvil including a at least one impact surface. During an operational cycle of the orthopedic impactor tool, the motor may generate rotational motion that drives the linear motion converter. The linear motion converter may, while being driven by the rotational motion, convert the rotational motion into linear motion and communicate the linear motion to the thrown mass. The linear motion, communicated to the thrown mass, causes the thrown mass to accelerate and impact the at least one impact surface imparting a linear impact force on the anvil. The motor and the linear motion converter may operate on independent axes.

Orthopedic impactor tool

An orthopedic rotary tool may include a motor, a first clutch, a first drive path, a second drive path, a second clutch, a rotating mass, and an output anvil. The orthopedic rotary tool may drive, by the motor and the first clutch, a first drive path that causes the output anvil to rotate at a speed. The orthopedic rotary tool may selectively enable, by the motor and the second clutch, a second drive path that causes the rotating mass to engage to the output anvil and increase the speed of the output anvil.

Orthopedic rotary tool with reduced reactionary torque

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 rotary impactor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to impact the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary impactor. High frequency linear impacts by the impactor obviate the need for a surgeon to provide an external push force on the impactor in order to perform a successful surgical operation.

Intermediaries for a robot and robotic end effector for orthopedic surgery operatively couple a surgical robot to an end effector of such a robot. The intermediaries therefor comprise means to absorb and/or counteract reactionary forces from the end effector (which end effector may, as an example, be a surgical tool) and to reduce forces that would otherwise be imparted on the robot. An intermediary comprises a sleeve of shock-absorbing material that couples the robot and end effector. Another intermediary comprises an isolation connector that provides for an indirect coupling between the robot and the end effector and includes an absorption means for absorption or dispersion of reactionary forces from the end effector.

Intermediaries for robots and robotic end-effectors for orthopedic surgery

An orthopedic impacting tool including 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. Alternatively, the tool may comprise a gas spring assembly system for generating an impact force. 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.

Orthopedic device delivering a controlled, repeatable impact

Various exemplary surgical impacting tool interfaces and methods of using surgical impacting tool interfaces are provided. In general, a surgical impacting tool includes a locking assembly configured to releasably attach to an adapter. In response to engagement with the adapter, the locking assembly is configured to move from an unlocked configuration, in which the adapter is not releasably attached to the surgical impacting tool (nor is any other adapter releasably attached to the surgical impacting tool via the locking assembly), to a locked configuration, in which the adapter is releasably attached to the surgical impacting tool via the locking assembly. The locking assembly is configured to receive the adapter in a longitudinal direction along a longitudinal axis defined by the locking assembly and to automatically lock the adapter to the surgical impacting tool.

Surgical impacting tool interfaces

A rotary tool may include a motor, a first clutch, a first drive path, a second drive path, a second clutch, a rotating mass, and an output anvil. The rotary tool may drive, by the motor and the first clutch, a first drive path that causes the output anvil to rotate at a speed. The rotary tool may selectively enable, by the motor and the second clutch, a second drive path that causes the rotating mass to engage to the output anvil and increase a torque delivered to the output anvil.

Rotary tool with reduced reactionary torque

A projectile includes a projectile housing with at least one compartment, an energizable energy storage means, a payload, a control circuit, and an initiator. The payload may be sequestered in one compartment of the projectile until the projectile is separated or opened. A ram element within the projectile may move within the projectile to cause the opening of a projectile. The projectile may include a means for activating the initiator via dynamic induction. In an example embodiment, the projectile comprises a coil that is operatively coupled to a magnetic element of a launcher. The projectile may be charged dynamically as via interaction between the coil and magnetic element as the projectile moves within the launcher.
