Stryker Hermes Ready Pump
Stryker · Model Hermes Ready Pump
Speech Recognition - There are two types of speech recognition systems - those for dictation and those for voice control. The primary differences between the two are the size of the vocabulary and the speech recognition accuracy. Dictation systems commonly incorporate thousands of words in their vocabulary; however, the speech recognition accuracy is not acceptable for the OR environment. Conversly, systems such as HERMES Control Center utilize a finite vocabulary resulting in extremely high speech recognition accuracy. In addition, HERMES speech technology has one- time pronunciation training session so the recognizer can learn the characteristics of each surgeon's voice. The HERMES platform was developed specifically for the challenging operating room environment where safety, accuracy and dependability are mission critical. Advances in endoscopic surgery have reduced procedural efficiency by adding numerous ancilliary devices which must be constantly monitored and adjusted. The HERMES network was designed to optimize the efficiency of the OR team in these complex situations. Speech recognition provides the most natural interface to deliver direct control of these devices to the surgeon, thereby increasing the efficiency of the OR team. The HERMES speech engine is designed to recognize the specific surgeon's voice model- and only the words in its vocabulary. This allows the surgeon to naturally interact with the OR staff without inadvertently activating peripheral devices. Video Feedback - Because the endoscopic surgeon's focus is on the video monitor, the HERMES Control Center provides a graphic display of peripheral device information. This overlay provides both navigation of system capabilities and device status in an easy-to-understand universal format. The surgeon maintains focus on the procedure while still using multiple peripheral devices efficiently. Audio Feedback - The HERMES Control Center provides audiable voice feedback to close the "voice control loop". This simple confirmation lets the OR team know that the commands were recognized and acted upon, enhancing communication and productivity by minimizing time spent investigating device status. It confirms critical functions and explains otherwise unclear device feedback. Touch-Screen Pendant Control - In addition to voice- control, a touch- screen Pendant provides auxiliary control of all HERMES- Ready devices from a single location, in or out of the sterile field. The Pendent controller utilizes a universal user interface for all HERMES- Ready devices, which simplifies the control of non- standardized devices.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not reach or hold set joint / cavity pressure
HighSymptoms: Pressure droops or overshoots, poor distension, pressure or flow alarm.
Root cause: Pump-head / roller wear, a pressure-sensor fault, a leak in the tubing / inflow-outflow, or a blocked cannula.
Tubing / cassette-detection fault
MediumSymptoms: Cassette / tubing not recognised, will not prime, leaks at the pump head.
Root cause: Cassette-detection switch or worn pump-head seals.
Outflow / suction-control fault
MediumSymptoms: Poor outflow, cannot clear debris, outflow alarm.
Root cause: Outflow pump / valve or a blocked suction line.
Shaver / handpiece fault (shaver systems)
MediumSymptoms: Blade will not oscillate / rotate, weak cut, handpiece not recognised, footswitch dead.
Root cause: Worn shaver handpiece / motor, or its cable / footswitch.
Display / control fault
LowSymptoms: Unresponsive touchscreen or keys, will not power on.
Root cause: Display / control board or power supply.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set pressure / poor distension
- Fit a fresh tubing set / cassette and re-prime.
- Confirm the inflow and outflow cannulae are patent and connections are tight.
- Run the pump self-test and verify the set pressure against a gauge if possible.
- Inspect the pump-head rollers / seals for wear.
- Replace the pump head or pressure sensor as isolated.
Symptom: Shaver will not run (shaver systems)
- Swap the shaver handpiece and cable.
- Check the footswitch and its connection.
- Confirm the console recognises the handpiece.
- Test forward / reverse / oscillate modes.
- Replace the handpiece or refer the console output as isolated.

Stryker Medical has identified that on some units of the MTA7900, there is a lack of a water temperature display while the unit is in Auto mode. While in Auto mode, only the patient temperature is displayed along with the set point. The water display will be blank during Auto mode. If the user wants to see the water temperature displayed and switches out of Auto mode to Manual mode, then back to

This recall is related to the Electi-cord recall. There is a risk when excessive force is applied to the plugs, a fracture can develop on the prongs inside the molded section of the plug. Over time the fracture may lead to arcing inside of the molded sction of the plug and a build up of heat which can cause charring, electric shock or fire. To this date there have been zero complaint for this fa
