An implant for an artificial hip joint and, more specifically, a dual mobility acetabular cup assembly for an artificial hip joint is configured to have improved locking mechanism between a liner and a shell and improved resistance to micromotion and to guide the liner into the shell with proper orientation by providing stable liner-shell fastening structure to the acetabular cup assembly.

A dental implant cleaning or chemotherapeutic treatment device includes an elongated hollow stem, and bristles operably attached to the elongated hollow stem adjacent a first end of the elongated hollow stem and projecting from the elongated hollow stem nonparallel to the elongated hollow stem.

The invention relates to a method for modification of a biocompatible component. The method of the invention includes the steps of a) providing a biocompatible component at least partly covered by metallic oxide; and b) treating at least a part of the component, which part is covered by the metallic oxide, with an aqueous composition that includes oxalic acid; whereby a modified metallic oxide, is obtained. The invention also relates to a biocompatible component-including a substrate having a surface with a) a microstructure including pits separated by plateus and/or ridges; and b) a primary nanostructure being superimposed on the microstructure, the primary nanostructure having depressions arranged in a wave-like formation.

A method and apparatus to autonomously analyze the surface area and alloy composition ratios of a metallic implant, such as an orthopedic implant, so that an optimal voltage for biofilm disruption can be selected and make treatment easier based at least in part upon the autonomous detection of a hydrogen evolution reaction threshold.

Device for cleaning a cone of an implant comprises a handle piece, an inner sleeve and an outer sleeve. The handle piece has a through opening extending axially. The through opening has a first section with a larger inner diameter than a second section. The inner sleeve inserts into the second section of the through opening and has a protrusion abutting against an abutment surface between the first and the second sections. The outer sleeve slides over a section of the handle piece. The handle piece and the inner sleeve fix a first part of a textile piece between the protrusion of the inner sleeve and the abutment surface of the handle piece. The handle piece and the outer sleeve fix a second part of the textile piece between the handle piece and the outer sleeve when the outer sleeve is slid over the handle piece.

Devices and methods for keeping an internal cavity of an implant or specifically an internal cavity provided in a fixture constituting an implant in a clean state by a simple operation without injuring the gingiva around the fixture is provided. A brush for cleaning the inside of an implant provided with a twisted brush part in which helical brush bristles are formed around the wire rod by arranging a large number of resin fibers in parallel in a direction perpendicular to a wire rod and then, by twisting the wire rod, an intermediate columnar part to which the twisted brush part is fixed, and a main columnar part to which the intermediate columnar part is fixed, where a length in a major axis direction of the intermediate columnar part is within a range of 0.8 to 2.0, assuming that a length in a major axis direction of the twisted brush part is 1.

A system for debriding an infected implant area includes an ultrasonic tool, a navigation system for tracking movement of the ultrasonic tool, and a processing circuit programmed to determine an area to debride and control the ultrasonic tool to automatically adjust a parameter of the ultrasonic tool to provide a first vibrational characteristic when debridement is of a surface of the implant and a second vibrational characteristic when the debridement is of patient tissue.

A device for intraoperatively disinfecting bone prostheses uses bioelectric effect. Advantageously, the device has an array that can be adapted to the shape of a bone prosthesis, wherein said array is provided with an arrangement of electrodes designed to connect to a programmable controller for supplying current, designed to perform a bioelectric treatment on the prothesis. The device may be connected to a programmable controller for supplying current to form a disinfection system, and a method for activating the same is also contemplated.

A fluid exchange electrode is defined by a multi-layered electrode body including a conductive electrode material layer disposed in an electrode body and an ionically conducting assembly that interfaces with the skin of a patient. A source of electrolytic fluid is coupled to an inflow tube and configured to permit a volume of electrolytic fluid to be circulated through the electrode body to increase treatment duration and overall electrode life in which the temperature of the cycled electrolytic fluid can be regulated. The cycled electrolytic fluid can be disposed of or preferably recirculated via a return or outflow tube to the source of electrolytic fluid. The herein described fluid exchange electrode can be used as part of a treatment system that applies a DC voltage in order to remove bacteria from a metal surgical implant.

Methods, systems, and devices for heating orthopedic implants are disclosed. The system includes an orthopedic implant receiving heat from a heating device. The heating device includes a heating element and a casing supporting or housing the heating element. A control unit provides precise and reliable operation of the heating element by managing power delivery, regulating temperature, and ensuring safe and effective functioning of the heating device during orthopedic surgical procedures. The casing is shaped and dimensioned for engagement with an orthopedic implant. Briefly, according to the method, resistive heat is applied to the orthopedic implant by first accessing an exposed implant surface, applying a retractor instrument to aid in exposure of the orthopedic implant and protection of surrounding soft tissues, attaching a heating device to the exposed implant surface, and activating the heating device.
