20150305817 | SURGICAL INSTRUMENT HOLDER FOR USE WITH A ROBOTIC SURGICAL SYSTEM - Described herein is a surgical instrument holder for use with a robotic surgical system, for example, during spinal surgery. In certain embodiments, the surgical instrument holder is an interface between the robotic arm and a surgical instrument used during surgery. This interface may hold the surgical instrument precisely, rigidly, and in a stable manner while permitting a surgeon to easily and quickly install or withdraw the instrument in case of emergency. | 2015-10-29 |
20150305818 | WASHER/DISINFECTOR - A washer/disinfector having a washing chamber dimensioned to receive articles to be washed. The washing chamber has a sump at the bottom thereof for collecting fluids used in the washing chamber. A fluid-heating system comprised of a steam generator is connected to a steam-to-fluid heat exchanger. The fluid-heating system has an exhaust port disposed in the washing chamber for exhausting residual steam from the heat exchanger into the washing chamber. | 2015-10-29 |
20150305819 | Cannulated Instrument Flushing and Cleaning Instrument - An apparatus for cleaning cannulated surgical tools comprises a hollow body with lavage fluid holes at a first end along with a brush adaptor affixed to the hollow body. An inlet adaptor is affixed, having to a second end of the hollow body. A body hub, consisting of inlet channel and drain channel is in liquid communication with an inner lavage fluid tube. A lavage connection tube is in liquid communication with the hollow body at the brush adaptor and through the upper connecting lavage fluid orifice. An inner lavage fluid tube, having an inner channel, extends within the hollow body with a distal end in liquid communication at a proximal end of the inner channel within the inlet adaptor. There are multiple spray openings proximate the distal end of the inner lavage fluid connection tube and a tube brush is dimensioned to fit within the inner channel. The apparatus can be provided with attachment members and combined with a reservoir to make the unit self-contained. | 2015-10-29 |
20150305820 | SELF-CLEANING TISSUE REMOVAL INSTRUMENT AND METHOD OF USE - A self-cleaning tissue removal instrument is disclosed and described herein. The self-cleaning tissue removal instrument generally comprising: a handle operably coupled with a proximal end of a rail portion; a jaw portion operably coupled to a distal end of the rail portion, a longitudinal axis running along the proximal portion to the distal portion of the self-cleaning tissue removal instrument; wherein the jaw portion is moved from an open position to a closed position by operation of the rail portion translating along the longitudinal axis of the self-cleaning tissue removal instrument, and the jaw portion clamps down and removes tissue in the closed position; and a cleaning mechanism operably coupled with the rail portion, whereby the cleaning mechanism disengages any tissue attached to the jaw portion when the jaw portion longitudinally translates to the open position. | 2015-10-29 |
