A robot system that includes a robot face with a monitor, a camera, a speaker and a microphone. The system may include a removable handle attached to the robot face. The robot face may be controlled through a remote controller. The handle can be remove and replaced with another handle. The remote controller can be covered with a sterile drape or sterilized after each use of the system. The handle and remote controller allow the robot to be utilized in a clean environment such as an operating room without requiring the robot face to be sterilized after a medical procedure. The robot face can be attached to a boom with active joints. The robot face may include a user interface that allows a user to individually move the active joints of the boom.

The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The pedal mounts upon the base and pivots. The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical signal of the pedal into a control signal based on the pedals position and/or orientation. The wireless interface couples the encoder assembly to receive the control signal. The wireless interface also couples the surgical footswitch to a surgical console operable to control and direct surgical equipment. The wireless interface passes the control signal from the encoder to the surgical console, which then directs the surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in the surgical theater. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch.

A wireless operating room communication system provides wireless transmission of video signals from a wireless camera or a wireless transmitter unit to a portable wireless display unit. A wireless multiple device control unit is in wireless communication with the transmitter unit, the display unit, and a plurality of surgical devices disposed within the operating room. Each of the surgical devices has a video receiver to obtain a video signal to synchronize the devices and units. The video transmitter unit has a video transmitter and the other units or devices have a non-video transmitter. The arrangement enables transmission of device control signals on the same channel as the video signal. In response to changes in bandwidth, the video transmitter unit reduces the video signal to enable transmission thereof to the video display unit, while maintaining robustness of the control signals.

A mobile apparatus and method to sterilize surgical trays. A cabinet has filtered cabinet roof vents, filtered cabinet floor vents, door(s) sealably covering a cabinet front aperture, shelves sized to support surgical trays, and wheels. Surgical trays are placed within the cabinet, the cabinet doors are closed, and the mobile apparatus is placed within an autoclave and sterilized. The cabinet doors are not unsealed until the cabinet is in the operating room, ready for use. During use in the operating room, doors are opened, trays removed, and their contents used. Wheels on the cabinet facilitate moving the cabinet from autoclave to storage or operating room. Chemical indicators and a locator card may be used to verify the sterilization status and autoclave history of the cabinet and its contents. Method steps include periodically replacing the filters and door gasket.

ClotFoam is a surgical sealant and hemostatic agent designed to be used in cases of non-compressible hemorrhage. It can be applied in the operating room through laparoscopic ports, or directly over lacerated tissue in laparotomy procedures or outside the operating room through a mixing needle and/or a spray injection method following abdominal, chest, extremities or other intracavitary severe trauma to promote hemostasis. Its crosslinking technology generates an adhesive three-dimensional polymeric network or scaffold that carries a fibrin sealant required for hemostasis. When mixed, Clotfoam produces a foam that spreads throughout a body cavity reaching the lacerated tissue to seal tissue and promote the coagulation cascade.

The viscoelastic attachment properties of the foam as well as the rapid formation of a fibrin clot that ensure that the sealant remains at the site of application without being washed away by blood or displaced by movement of the target tissue .

An integrated and modular air and lighting plenum that is the primary directional lighting mounting apparatus and laminar flow diffuser of an HVAC system in a healthcare setting. The plenum provides laminar air flow from the ceiling to the room in which it is located in accordance with HVAC requirements for healthcare environment settings, by using a plurality of cylindrical airflow outlets. The use of cylindrical airflow outlets promotes laminar airflow by reducing sharp boundaries that induce turbulence (e.g., the corners of rectangular or square outlets) and creates a highly sterile environment around the patient and staff in the operating room. The surgical lights used in the integrated air and lighting plenum allow the beam direction, spot size, focal point, brightness, and color temperature of the emitted light to be controlled.

A medical supply such as an operating room towel, laparotomy sponge, gauze pad, bandage, or swab with radio frequency detectable material which eliminates the need for re-entry into a patent after operating in situations where medical supplies are missing. The patent can be easily scanned with a handheld scanner to determine if the medical supply was accidentally left inside the patient. If no RF detectable material is observed, unnecessary re-entry into the patient is prevented. The radio frequency detectable material is incorporated into the medical supply as a tag, in the handle, as a handle, stitched to the medical supply, woven into the medical supply, or sewn into a seam in the medical supply. An identifier on the medical supply indicates that the medical supply is an RF detectable medical supply. In addition to preventing unnecessary re-entry, scanning for RF detectable material is much safer than scanning for x-ray detectable material.
