Abstract: A tool includes an elongated handle with an end recess and a side notch for latching, and a plurality of different replaceable heads. Each replaceable head includes an elongated rectangular section shaped to fit stably into the recess for providing torsional and lateral support, an operative end, and a latch releasably engaging the side notch to retain the head in the recess. The different heads can include different operative ends with structure for providing different operative functions, such as a head with oppositely-positioned partially-shielded blade tips and/or with different blade throat sizes, a head with pizza-cutting wheel, a head with hammer or wrench feature, and the like.

Abstract: A remotely controlled powered chair may include a support frame, a seat pivotally mounted on the support frame, an rotary actuator mounted between the support frame and the seat to drive the seat to move relative to the support frame, a backrest pivotally mounted on the seat, and a linear actuator mounted between the seat and the backrest to drive the backrest to move relative to the seat. Thus, the rotary actuator may be controlled by an electrically control device to drive the seat to pivot relative to the support frame reciprocally in a pendulum manner so that the seat is pivoted relative to the support frame automatically. In addition, the linear actuator may be controlled by the electrically control device to adjust the inclined angle of the backrest so as to provide a comfortable sensation to the user.

Abstract: An intervertebral implant includes a body adapted to be implanted into an intervertebral space of a patient, the body defining a fusion aperture, and at least one cartridge with each cartridge disposed in the body and at least partially extending into the fusion aperture. Each cartridge includes an impedance sensor configured to measure electrical resistance, a radio frequency (RF) transmit antenna configured to transmit a RF signal, and circuitry for recording data from the impedance sensor and transmit the recorded data to an external clinician computing device through the RF transmit antenna. Such collection and use of data can be used to provide improved orthopedic outcomes.
