Abstract
A method for cleaning a surface that is selected from at least one of a medical device surface and a soft tissue surface includes the steps of: contacting the surface with bristles of a moving brush head that is part of a powered hand-held device; and dispensing onto the surface an irrigation fluid through the brush head and a dispensing opening formed along the brush head.
Claims22
A method for cleaning a surface that is selected from at least one of a medical device surface and a soft tissue surface comprising the steps of:
- contacting the surface with bristles of a movable first brush head that is part of a powered hand-held device;
- and
- operating the powered hand-held device in at least one of an oscillation operating mode and a sonication operating mode, each of the oscillation operating mode and the sonication operating mode having a plurality of different operating speeds, wherein in the oscillation operating mode, the movable first brush head oscillates between 7,000 to 36,000 movements per minute and wherein in the sonication operating mode, the movable first brush head vibrates to generate high frequency waves between 20 kHz and 20 MHZ.
The method of 1, wherein the first brush head is operated in the oscillation operating mode and the method further includes the steps of:
- removing the first brush head and attaching a second brush head to the powered hand-held device;
- and
- operating the second brush head in the sonication operating mode.
A method for cleaning a surface of a medical device and for cleaning a soft tissue surface comprising the steps of:
- providing a hand-held device that has a handle;
- coupling a first brush head to the handle for cleaning of the surface of the medical device, wherein the first brush head has a plurality of first bristles;
- operating the hand-held device at at least one of a first oscillation operating mode and a first sonication operating mode to clean the surface of the medical device;
- coupling a second brush head to the handle for cleaning tissue surrounding the medical device, wherein the second brush head is different than the first brush head and includes a plurality of second bristles;
- and
- operating the hand-held device at at least one of a second oscillation operating mode and a second sonication operating mode to clean the tissue surrounding the medical device, wherein second oscillation operating mode has a speed less than the first oscillation operating mode and wherein the second sonication operating mode has a speed less than the first sonication operating mode and wherein the speeds of the first and second oscillation operation modes are between 7,000 to 36,000 movements per minute and wherein the speeds of the first and second sonication operating modes are between 20 kHz and 20 MHZ.
