One of the new clinical techniques to assess the lower body parameters is the wearable ultrasonic sensors. The device which can measure the static and dynamic balance abilities in sport and clinical setting by the traveled signals of ultrasonic transmitter and receiver between two feet was developed and validated. The new device consisted of a pressure gauge and a digital centimeter indicator a...

An ultrasonic orthopaedic surgical device is presented, where the ultrasonic actuation relies on a modification of the classical cymbal transducer. All current devices consist of a Langevin ultrasonic transducer with a tuned cutting blade attached, where resonance is required to provide sufficient vibrational amplitude to cut bone. However, this requirement restricts the geometry and offers lit...

A conformable phased array device is being developed that allows reliable ultrasonic inspection of components with irregular surfaces. The device uses a standard linear phased array transducer, which is coupled to the surface under test by a water path, encapsulated by a low loss, synthetic rubber membrane. A comparison of results obtained using conventional ultrasonic techniques and the confor...

OBJECTIVE The purpose of this study was to evaluate the potential benefit of an ultrasonic device in apical surgery on the outcome of treatment. STUDY DESIGN A randomized prospective design was used in a standardized treatment protocol. Patients were allocated to treatment with an ultrasonic device (P-Max Newtron) or treatment with a bur in an otherwise similar protocol. One year after treatm...

A novel multi-fingered exoskeleton haptic device using passive force feedback has been proposed by the authors. The haptic device solves the conventional problems of previously developed master-slave systems with force feedback, such as oscillations, complex structures and complicated control algorithm. However, some problems still remain in the conventional passive elements. In the present pap...

The aim of this study is to demonstrate the ability of our ultrasonic endodontic dental device with rotary nickel-titanium alloy instruments for the root canal treatment. This study is aimed at investigating the cleaning and shaping efficacy with “Ultrasonic device for endodontic treatment of dental’s canals. The purpose of root canal treatment is to get rid of the damaged pulp and the bacteria...
