    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 includes an extensible polymer assembly and a fastener drive assembly, such that when said extensible polymer assembly is actuated (by a motor and linear motion converter), energy is stored as an extensible polymer of the polymer assembly extends in length and force from said extensible polymer is applied on said fastener drive assembly. When said extensible polymer reaches a sufficient extension, a retention means releases said fastener drive assembly and wherein said fastener drive assembly moves from a first position to a second position such that an anvil of the fastener drive assembly is capable of driving a fastener into a substrate.

    摘要: An orthopedic impacting tool comprises a motor, a linear motion converter, an air chamber, a compression piston, an impacting element, an anvil element, and a broach adapter. The compression piston may cause the impacting element to apply controlled force on a broach adapter to create a precise opening for subsequently disposing a prosthesis in a patient. 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 fastener driving apparatus for driving fasteners into a substrate. The fastener driving apparatus is a combination of a motor driven linear motion converter; a compression cylinder; an expansion cylinder and a valve arrangement. The linear motion converter converts a rotational motion of a motor to a linear motion of a compression piston within the compression cylinder causing a gas within the compression cylinder to be compressed. The compressed gas is communicated to the expansion cylinder through the valve arrangement wherein the compressed gas expands causing an anvil coupled to an expansion piston within the expansion cylinder to move axially. The axial movement of the anvil causes a fastener to be driven into the substrate. The fastener driving apparatus is an ergonomically designed portable hand held tool providing comfort to a user, meeting safety standards and performance efficiency requirements.

    摘要: A fastener driving apparatus includes a vacuum piston and a drive piston, which vacuum piston, when moved (by way of a motor and linear motion converter), draws a vacuum against the drive piston, which drive piston may be held in place by retention means. An anvil is coupled to the drive piston. The retention means is released electrically or mechanically at or near the point of maximum vacuum volume. This drive piston and anvil assembly is then driven by atmospheric pressure and may strike as fastener to drive it into a substrate. At least one position sensor may be used. Once the fastener is driven, the apparatus may reset to an initial position. At least one valve may be included to dump the energy stored in the vacuum in the case of a jam condition, thus providing good safety profile.

    摘要: A compact impacting apparatus includes a spring anvil assembly with a spring, an anvil, and a barrel cam. A cam follower engages the barrel cam to energize the spring anvil assembly. The spring anvil assembly is thereafter released to impact a striker, which striker delivers impact force to an impact target. The spring anvil assembly may be biased in a starting operational position by the weight of the apparatus or the impact target. The spring anvil assembly may be disposed against a rotating pusher plate while engaged by the cam follower. Force of impact may be adjusted by repositioning the pusher plate and or changing the compression of the spring of the spring anvil assembly. The cam follower provides for repeated impacts upon the impact target and the striker holds the impact target in place for effective impacting.

    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 capacity, the second piston and the anvil to retract to their initial positions.
