A device and a method for switchable vibration modal ultrasonic are provided. The device includes a hollow shaft, an ultrasonic motor, a limit shell, an electromagnet, a moving tool head, a vibration source and a tool head. The structure design of the ultrasonic motor, the magnetostrictive materials and the drive coil combination of different functions are configured so that, without changing the condition of components, the ultrasonic can switch mode, namely the longitudinal vibration, torsional vibration, and longitudinal and torsional vibration in three different vibration modes. During the operation of the device, different vibration modes are excited without changing the parts, which meets the machining requirements of different vibration forms. Meanwhile, the operation is more convenient and faster, and the overall design structure of the device ensures the efficient and safe operation of the device.

Devices, systems and methods are provided for treating migraine headaches and other conditions by non-invasive electrical stimulation of nerves and other tissue. A hand-held device includes a housing with a controller having a signal generator, an electrode for delivering electrical signals, and a conductive surface configured as a return path for the electrical signals. In certain implementations, the electrode is repositionable with respect to the housing. The patient can self-apply the hand-held device by pressing it against areas in need of pain relief. The device may include a pressure-sensitive gating switch to control delivery of the stimulation therapy. In certain embodiments, the electrode is a rollerball electrode. The device may include a chamber for retaining and dispensing conductive gel to the therapy site. In certain approaches, the device includes an electrode support for coupling an electrical stimulation system to the head for hands-free electrical stimulation therapy.

The invention discloses an electrochemical device for treating cancer, characterized by using an acupuncture needle as a working electrode to produce hydrogen in a tumor tissue, thereby destroying the tumor tissue through the produced hydrogen gas. The device of the invention has low cost and simple operation, can realize minimally invasive treatment, and is green and environmentally friendly.

A health-care device includes a work piece having an operating end and a opposite working end to perform a health-care work on a specific part or an acupoint of a body part of a user; a work body at its lower part the operating end is mounted so that a specific working relationship between the working end and the specific part or the acupoint is maintained; and a device positioning piece connected to the work body for maintaining a specific positional relationship between the working end and the specific part or the acupoint.

Embodiments of medical treatment including skin treatment using electrical energy, especially with the primary purpose for skin treatment for aesthetics are described generally herein. Other embodiments may be described and claimed.

A system for obtaining and analyzing data for overall joint motion from a plurality of joints of a subject experiencing a movement disorder involves a plurality of kinematic sensors configured to be placed on a body of a subject proximal a plurality of joints. The kinematic sensors are selected to measure overall joint motion with sufficient degrees of freedom for individual joints so that data collected by the sensors can be deconstructed into multiple degrees of freedom for individual joints and analyzed to provide amplitude of the movements caused by the movement disorder and/or relative contributions from and/or directional bias for each muscle group that may be implicated in the movement of each joint. The system permits determining a treatment regimen based on the amplitude of the movements and/or the relative contribution and/or directional bias of each muscle group to the movements caused by the movement disorder.

A holder apparatus for enabling secure coupling of a variety of medical tool types, having different head member configurations, to a medical device. The apparatus has at least two housing portions that open and close to receive the head member, and an adjustment mechanism that adjusts to the height and/or shape of the head member, such that there is no relative movement between the housing portions and the head member. The adjustment mechanism may be a ratchet mechanism, a semi-flexible fastener, or a moldable material disposed on one or more of the housing portions. There may be a locking mechanism to lock together the housing portions, and a tightening mechanism to secure the grip of the housing portions on the head member. The housing portions may be configured to allow removal of at least a portion of the medical tool from the device.
