    摘要: A fastener driving apparatus includes a power source, a control circuit, a motor, a first hollow guide member having a first volumetric capacity, a first piston, a linear motion converter, a second hollow guide member having a second volumetric capacity, a second piston, an anvil, a valve arrangement and at least one sensor. The guide members may have an elliptical or oval cross-section. During a compression stroke, the first piston compresses gas in the first hollow guide member. The valve arrangement opens and communicates the compressed gas to the second hollow guide member, causing the second piston to move the anvil to drive a fastener. During a return stroke of the first piston, the valve arrangement opens, communicating a vacuum created in the first hollow guide member to the second hollow guide member, thereby causing the second piston and the anvil to retract to their initial positions.

    摘要: A fastener driving apparatus includes a power source, a control circuit, a motor, a first cylinder, a first piston, a linear motion converter, a second cylinder, a second piston, an anvil, a retention element retaining a component of the apparatus, and at least one sensor. During a compression stroke, the first piston compresses gas in a first cylinder to a predetermined pressure. Compressed gas is communicated to the second cylinder and the retention force of the retention element is overcome, to release the retained component of the apparatus, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke of the first piston, a vacuum created in the first cylinder is communicated to the second cylinder, causing, along with an optional other retraction means, the second piston and the anvil to retract to their initial positions.

    摘要: An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, a striker, a detent and a broach adapter. The compression piston may cause the striker to apply controlled force on a adapter to create a precise opening for subsequently disposing a prosthesis in a patient. The detent may hold the striker in a position until a sufficient pressure is applied to release the striker. The tool allows forward or backward impacting for expanding the size or volume of the opening or for facilitating removal of the broach and tool from the opening. A force adjustment control of the tool allows a user to increase or decrease the impact force. A light source and hand grips improve ease of operation of the tool.

    摘要: 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.

    摘要: A fastener driving apparatus comprises an energy storage means, a drive mechanism, and an anvil assembly. The drive mechanism selectively engages the energy storage means to store potential energy within the energy storage means. After the drive mechanism disengages, potential energy previously stored within the energy storage means impart a force on the anvil assembly to launch the assembly (and incorporated anvil) to drive a fastener. The drive mechanism may comprise a cam for engaging and disengaging the energy storage means. The apparatus may also comprise a nail indexing mechanism for supplying fasteners, which indexing mechanism may also be acted and operated on by the cam. The apparatus may further comprise a gas spring as a return mechanism for returning the anvil assembly to a position after the anvil assembly has separated from the energy storage means.

    摘要: A fastener driving apparatus includes a drive mechanism, a drive piston disposed with in a cylinder and operatively coupled to the drive mechanism, and an anvil coupled to the drive piston. The apparatus also preferably comprises a biasing element for temporarily holding the drive piston at BDC of the piston cylinder. The drive mechanism is capable of selectively applying force on the drive piston to move the drive piston away from BDC of the piston cylinder. When the drive mechanism engages the drive piston to move the drive piston away from BDC, a vacuum is generated in the cylinder, which vacuum, after the drive mechanism disengages the drive piston, acts on the drive piston to cause the piston to move toward BDC and the anvil to drive a fastener. A sealed air chamber on the side of the piston opposite the vacuum may assist in generating force.

    摘要: A fastener driving apparatus comprises a gas spring or spring, a drive mechanism, an anvil assembly, and an anvil. The drive mechanism permits transition from engagement with the gas spring, spring or anvil assembly to disengagement from the gas spring, spring or anvil assembly. The anvil and/or anvil assembly are operatively coupled to the gas spring or spring such that after the drive mechanism disengages them, the gas spring piston or the spring moves to imparts a force on the anvil to cause the anvil to move and drive a fastener. The mass of the anvil assembly is preferably greater than 50% of the total mass of the anvil assembly and gas spring moving mass. The gas spring is configured such that the pressure increase during the movement of the gas spring piston by the drive mechanism is less than 30% of the initial pressure in the gas spring.
