The present disclosure relates to a cervical traction apparatus designed for therapeutic use, featuring an anchor point for secure attachment. The apparatus comprises a cohesive framework assembly primarily composed of parallel extension springs and two connection panels. Integral components such as a head halter, a spreader bar, a positioning mat, and an adjustable chain are included. The apparatus is specifically configured to apply traction force by harnessing the restoring force generated by the parallel extension springs. The design facilitates the fine-tuning of traction force by adjusting the number of parallel extension springs. The apparatus is intended for the patient to adopt a standing position, promoting active stretching during the traction session. It can also be employed while seated, in conjunction with a user-provided chair. The design recognizes the interdependent relationship between the cervical spine, associated muscles, and other spinal components, treating them as a unified entity during the traction process.

A method for performing a surgical procedure includes: positioning a patient in a surgical patient interface device that includes: a base, a platform coupled to the base, and a first abutment and a second abutment each coupled to the platform; rotating the platform between a first position and a second position, where, in the first position, the platform extends in a substantially horizontal direction relative to the base, and the first and second abutments are separated by a first distance, and in the second position, the platform extends in a substantially vertical direction relative to the base; adjusting one or both of the first and second abutments relative to the platform such that, in the second position, the first and second abutments are separated by a second distance different from the first distance; and accessing a target portion of skin of the patient for the surgical procedure.

A postural lifting exoskeleton includes: a chair, in which (i) the chair includes a first portion and a second portion and (ii) a first armrest is affixed to a right side of the first portion and a second armrest is affixed to a left side of the first portion; a set of electric actuators including at least a first electric actuator and a second electric actuator, in which, upon receiving a first request from a user via a first control panel, a second control panel triggers at least the first electric actuator and the electric actuator to transform the exoskeleton from a first position to a second position; and a footplate, in which, once the user is in an orthostatic position, the footplate's oscillatory movement causes the user's ankles to move upwards and downwards in order to improve the user's blood circulation.

A dynamic counterbalance system is provided. The dynamic counterbalance system can include a compound pulley system and an adjustment arm. The compound pulley system can include a frame, a spring, a variable radius pulley, a plurality of mounted pulleys, a plurality of moveable pulleys, and a plurality of lines. The adjustment arm can include a mountable support, a spool support, a spool, an arm inner support, a rod support, an extended rod, a rod end cap, a traveling pulley, a dynamic pulley, and a plurality of lines.

A spinal decompression system and method, for safely and comfortably applying gravity-based lumbar traction to a user in a vertically suspended position, includes a spinal decompression device having an upright frame and a traction assembly suspended from the frame by a crossed strap. A forward harness support assembly is provided to attach to the traction assembly and hold the traction assembly in a forward condition relative to the upright frame.

The massage machine frame of the present invention comprises a base and a seating unit which is supported to the base in such a way that the seating unit is movable relative to the base, wherein one of the base and the seating unit has a guide rail and the other has a mating portion cooperating with the guide rail, the guide rail including: a first guide rail in the shape of a circular arc projecting forward; and a second guide rail in the shape of a circular arc projecting rearward and having a different center of circle than the first guide rail, the mating portion including: a first mating portion switchable from moving on the first guide rail to moving on the second guide rail; and a second mating portion which moves on the second guide rail.
