A device and method for fixation of bone fractures has a bone screw comprising a shank with a threaded end portion, on the outer surface. The screw has a through bore with two bore portions differing in diameter. A step in the diameter is formed between these bore portions and is located within the end of the screw having the thread. This step in diameter can support a metal insert which in turn supports a polymer pin when the latter if pressurized with a sonotrode in the bone screw. Together with an applied ultrasonic vibration the pressure fluidizes the polymer pin and presses the material through holes configured in the wall of the bone screw and into surrounding bone.

A punching device for preparing a recess in a bone has a punching tool usable for such a punching device. An implant usable with the punching tool is provided and a method for preparing a recess in a bone are disclosed. The punching device comprises an ultrasonic sonotrode and a punching tool which is fixable to the sonotrode at its proximal extremity. At its distal extremity, the punching tool has a thin-walled portion having a non-rotational symmetric cross-section. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. Subsequently, an implant can be held in such recess. Due to its lack of rotational symmetry, the implant may absorb rotational forces around its longitudinal axis.

An electro acoustic device and related method for increasing production capacity of wells that contain oil, gas and/or water is disclosed. The electro acoustic device produces vibrations stimulating occurrence of mass transfer processes within the well. The resultant acoustic flow generated in porous media, produced by superposition of longitudinal and shear waves, is developed over a characteristic frequency threshold value specific to water, normal oil and heavy oil, with an acoustic energy density capable of establishing higher fluidity zones in the porous media, promoting mobility and recovery of desired fluid and formation damage reduction in a wellbore. The down hole electro acoustic device is a submerged unit placed in the well producing zone, and consists of an electric generator, one or more electro acoustic transducers, and one or more waveguide systems (sonotrodes) that include tubular type radiators which provide transmission of elastic vibrations into the medium under treatment.

An ultrasonic handpiece is used for augmenting a bone screw. The handpieces comprise a housing, an ultrasonic converter shiftingly accommodated in the housing, and a sonotrode connected to one end of the ultrasonic converter. The sonotrode protrudes from the housing into the bone screw. An adjuster wheel is adjustably connected to the housing. A spring is provided the ends of which are supported by the ultrasonic converter and the adjuster wheel, respectively. The ultrasonic converter is preloaded in the direction away from the adjuster wheel by setting the adjuster wheel, thereby the sonotrode is urged with a selected force into the bone screw and the augmentation material is pressed out of the bone screw and into the bone.

A sonotrode and anvil are adapted for ultrasonic welding of work pieces, to produce a narrower weld region that exhibits greater durability, permitting use of less material per package. The horn-to-anvil contact is through a plurality of energy directors arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors include a series of plateau surfaces regularly spaced apart in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The energy directors of the horn are configured to interlock with the energy directors of the anvil. The rectangular-shaped plateaus are spaced apart by angled side-surfaces that form valleys. A stepped transition to a corresponding region of reduced height for the energy directors of the sonotrode and anvil may form a cosmetic seal region with a lesser integrity, in addition to the main barrier seal.

A handpiece is disclosed for a multifunctional instrument for endoscopic surgery. The handpiece comprises a case; a connector disposed on the case and adapted to be connected to connecting lines such as electrical lines, liquid supply and discharge lines, and the like; at least one ultrasonic transducer arranged in the case; an ultrasonic sonotrode transmitting the ultrasonic energy; and at least one switch for controlling functions of the handpiece. The handpiece is characterized by, among other things, the provision that the sonotrode includes a long and thin probe section with a duct composed of several segments which are welded to each other.

An electro acoustic device and related method for increasing the production capacity of wells that contains oil, gas and/or water is disclosed. The electro acoustic device is submerged in the well producing zone, and includes an electric generator, one or more electro acoustic transducers, and one or more wave guide systems (sonotrodes) that include radiators which transmit vibrations into the medium under treatment. The electro acoustic device produces vibrations that stimulate the occurrence of mass transfer processes within the well. According to one or more embodiments, shear vibrations are produced in the well bore region due to the phase displacement of mechanical vibrations produced along the axis of the well, achieving alternate tension and pressure due to the superposition of longitudinal and shear waves.

An apparatus for and method of disinfecting the interior surfaces of barrels and destroying microorganisms is disclosed. In one embodiment, an ultrasonic apparatus includes a sonotrode encased in a sheath, placed within a bunghole of a barrel. An ultrasonic generator is connected to the sonotrode. The ultrasonic apparatus also includes an ultrasonic transducer connected to the ultrasonic generator and associated with the sonotrode.

A specially designed sonotrode and anvil are adapted to be used in combination for ultrasonic welding of work pieces, to produce a narrower weld region, but one exhibiting greater durability, thereby permitting use of less packaging material. The contact surfaces comprise a surface of the anvil having a plurality of energy directors, where the plurality of energy directors are arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors may comprise a series of plateau surfaces being regularly spaced apart from each other in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The rectangular-shaped plateaus may be spaced apart by valleys. Engagement of the energy directors of the anvil with the corresponding surface of the sonotrode may cause minor elastic deformation of work pieces positioned therebetween prior to ultrasonic welding.

The ultrasonic welding device (1) comprises a continuously operable roller sonotrode (13). The power of the roller sonotrode (13) may be closed-loop controlled depending on other welding parameter in a manner such that long welding seams or adhesive seam with a uniform quality may be manufactured. The method may be used for manufacturing canopies, tarpaulins, or pieces of clothing

A method is furnished for a treatment of septic wounds. A hand piece of a sonotrode is connected to a liquid storage. Access to a wound is furnished to the sonotrode. A liquid atomized by ultrasound is delivered to the wound through a sonotrode channel disposed in the sonotrode. Bacteria in the area of the wound are destroyed by the ultrasound emitted by the sonotrode. The method allows to remove a prosthesis not longer desired from a patient. The area left open by the removed prosthesis and/or a bone is filled with a liquid. The sonotrode is then entered into the liquid for propagating ultrasound through the liquid and thereby destroying bacteria present in the liquid.
