The KLS Martin maxium® with maxium® Beamer is an electrosurgical unit designed for various surgical applications, offering both electrosurgery and argon plasma coagulation capabilities. This device is characterized by its comprehensive feature set, user-friendly interface, and robust design, making it suitable for a range of surgical procedures.

Function Description:

The maxium® is an electrosurgical unit (ESU) that provides high-frequency (HF) current for cutting and coagulation of tissue. It supports both monopolar and bipolar electrosurgery modes, allowing for precise tissue effects tailored to specific surgical needs. The unit is designed to deliver controlled energy output, ensuring effective and safe procedures.

When combined with the maxium® Beamer (MB402), the system extends its capabilities to include argon plasma coagulation (APC). APC is a non-contact technique that uses ionized argon gas to deliver HF current to tissue, resulting in superficial coagulation with minimal tissue damage and smoke production. This makes it particularly useful for diffuse bleeding, surface coagulation, and devitalization of tissue. The Beamer integrates seamlessly with the maxium® ESU, utilizing its HF generator and control system.

The device features a graphical user interface (GUI) with a screen module and protective glass pane, allowing for intuitive program selection and parameter adjustment. Users can select from a variety of pre-set programs or create and customize their own. The unit also includes a rotary switch for axial confirmation of selections and adjustments.

Important Technical Specifications:

While specific numerical specifications for HF output power (e.g., watts, voltage) are not explicitly detailed in the provided excerpts, the manual indicates that the unit can deliver HF output voltages up to 12 kVpp. It also mentions a 4kVp limitation setting, suggesting a capability to manage and potentially limit high voltages for specific applications. The device's power supply units (PSUs) and HF generator are critical components, with the main board and power manager board handling power distribution and control. The system incorporates capacitors that may remain energized for some time after the unit is turned off, highlighting the importance of safety precautions during servicing.

For the maxium® Beamer, the system monitors the argon gas cylinder's filling level. The pressure reducer's output pressure, which is identical to the Beamer's input pressure, is used to derive the indicated filling level. The system can measure pressures at 100 bar and 30 bar for calibration purposes. The alarm threshold for low gas levels can be adjusted between 30 and 80 bar, with a factory presetting of 30 bar, suitable for a 10-liter gas cylinder.

The unit includes a clock with calendar function, powered by a battery on the controller board, which supports log functions. This clock is set to Central European daylight saving time (CET) ex factory and does not automatically switch to standard time.

Usage Features:

The maxium® offers a highly customizable and user-friendly experience:

Program Handling: Users can select from standard programs or edit/create user-defined programs. Programs can be locked to prevent accidental modifications, and unlocked when temporary changes are needed. The unit can be configured to start with the last-used program or a standard program.
Beamer Parameters: When the Beamer is connected and gas supplied, users can access specific parameters for argon plasma coagulation. This includes calibration of the argon filling level indicator, setting the low-pressure alarm threshold, and viewing accumulated activation data (cycle power, cut activations with argon, coag activations with argon).
Device Settings: The "Settings" submenu allows for various background functions, such as setting the internal clock (year, month, day, hour, minute), enabling a 4kVp limitation, configuring the power bar graph display (measured power vs. set power), locking power adjustments during activation phases, and selecting activation tone schemes (Sound Scheme 1-4).
Intuitive Interface: The menu-driven interface, accessed via the MENU button, guides users through various settings. A service password (2020) is required to access the "Service" menu, preventing unintended changes by normal users. The rotary switch is used for navigation and confirmation.
Error Logging: The system registers operating troubles and malfunction incidences for both the ESU and the Beamer, saving this information in cyclical error logs. These logs can be displayed for diagnostic purposes and cleared after repairs.

Maintenance Features:

The service manual provides detailed instructions for maintenance and troubleshooting, emphasizing safety precautions due to high internal voltages.

Module Replacement: The manual outlines procedures for replacing various modules and components, including the front part, socket panel, HF output sockets, socket module indicators, rotary switch, ON-OFF button, front board, screen module, controller board, power manager board, monopolar board, bipolar board, main board, footswitch sockets, loudspeakers, power supply socket, serial interface unit, and argon beamer connector.
Calibration: The argon filling level indicator can be calibrated at two test pressures (100 bar and 30 bar) to ensure accurate readings. A "Reset to Standard" option is available for fixed values if calibration at specific pressures is not feasible.
Troubleshooting: The manual includes sections on troubleshooting, covering text messages displayed by the unit, module status lamps and their functions (for main board, controller board, power manager board, monopolar board, bipolar board), and faults in the power supply system, HF generator, energy flow path, and activation path.
Settings and Checks & Tests: This section details procedures for adjusting positions of the ME402, setting power manager, monopolar, and bipolar boards (with specific instructions for different hardware configurations like HW00-HW06), checking HF output power, and checking compliance with high-frequency leakage current limits.
Recurrent Safety Checks: The device requires recurrent safety checks according to IEC/EN 62353, ensuring ongoing compliance with safety standards.
Software Updates: The manual provides procedures for updating the operating program and subsystems of the ME402 and MB402, including normal and extended software updating procedures, and the use of the marFlash program. It also covers reading out and transferring unit settings, either back-to-back between units or to/from a PC using maxiumPC.
Factory Reset: A "Reset Programs" function allows for irreversibly deleting user-defined settings and restoring factory presets, useful for returning units to their original state after temporary use or repair.

Overall, the KLS Martin maxium® with maxium® Beamer is a sophisticated electrosurgical system designed for versatility, precision, and ease of maintenance, with a strong emphasis on user safety and operational reliability.
