Abstract: A cleaning system includes a surgical tool assembly having a longitudinal shaft and a sleeve surrounding the longitudinal shaft. The system includes an injector head and body that receive the assembly. The head has an inlet coupling that fluidly couples to a pressurized fluid source. The body couples to the head to house the assembly between the head and the body. The body has an outlet coupling to fluidly couple to a vacuum source. When the assembly is housed between the head and the body, at least one fluid pathway is formed between the inlet coupling, the head, the shaft and the sleeve, the body, and the outlet coupling. A positive pressure fluid source is coupled to the inlet coupling and a vacuum source is connected to the outlet coupling to establish a pressure differential across the fluid pathway sufficient to draw the fluid therethrough.

Abstract: An ossicular prosthesis is adjustable in length and temporarily and resiliently adjustable in angular orientation. The prosthesis includes a head for contacting a tympanic membrane, and a resilient sleeve is mounted within the head. An elongate shaft extends through the sleeve, and includes a distal end adapted to engage a footplate or stapes. The sleeve forms a resilient joint that allows the shaft to undergo an angular motion relative to the sleeve when subject to a non-axial force, and then subsequently return to its original position after the force is removed. The sleeve may also be longitudinally displaceable within the head of the prosthesis such that the shaft can undergo a damped linear motion. Also as a result of the arrangement of the sleeve, the prosthesis is adjustable to a very short length.

Abstract: A system includes a handpiece and a removable tool assembly including a holder body, a shaft, a cutting bur, a guard, and a sleeve. The body engages the handpiece and defines a bore. The shaft extends within the bore and the bur is provided to the distal end of the shaft. The guard is coupled to the body via a threaded mating at the bore, such that rotation of the guard relative to the body longitudinally displaces the guard. The extends within the bore of the body and the guard. The guard is positioned relative to the body by a distance to define a working length of the bur between the distal end of the guard and the distal tip of the bur. The working length of the bur is used to cut tissue, without concern that cutting will be deeper than intended.
