Description
Key Features and Function:
Current Transmission:
The monopolar handle uses a single active electrode to transmit electrical current from the cautery machine to the tissue, causing coagulation and tissue cutting.
Return Electrode:
The current returns to the cautery machine through a return electrode, often a pad placed on the patient’s body, completing the circuit.
Cut and Coagulation:
Monopolar cautery handles can be used for both cutting and coagulating tissue, depending on the settings of the cautery machine.
Versatility:
Monopolar cautery is suitable for a wide range of surgical procedures, including those involving the gastrointestinal tract and removal of polyps.
Types of Handles:
Monopolar handles come in various forms, including reusable and disposable options, with different electrode shapes and sizes to suit different surgical needs.
Advantages and Disadvantages:
Advantages:
Monopolar cautery is generally more effective for large areas and deeper tissue penetration compared to bipolar cautery.
Disadvantages:
The current travels through the body, potentially posing risks to surrounding tissues and organs if not properly managed.
Safety Considerations:
Return Electrode Placement:
Proper placement of the return electrode is crucial to ensure safety and prevent burns or other complications.
Patient Monitoring:
Careful monitoring of the patient’s vital signs and skin temperature during monopolar cautery is essential.
Contraindications:
Monopolar cautery may be contraindicated in patients with certain medical conditions or implants, such as cochlear implants.
