RF Surgery Equipments of ESU Electrodes

Electrosurgical Unit (ESU) along with various electrodes to cut tissue, coagulate blood vessels, or perform other surgical functions using high-frequency electrical currents .

• Electrosurgical Generator: Provides the electrical current needed for the procedure.
• LEEP Loop Electrodes: Various sizes and shapes of loop electrodes used to excise the abnormal tissue.
• Ball and Needle Electrodes: Used for coagulation and hemostasis.
• Insulated Speculum: A speculum coated with non-conductive material to protect the patient from electrical current.
• Smoke Evacuation System: Removes smoke generated during the procedure to maintain a clear field and reduce exposure to harmful smoke particles.
• Grounding Pad: Placed on the patient's skin to complete the electrical circuit and ensure safety.
• Colposcope: Magnifies the cervix for a detailed view during the procedure.
• Surgical Instruments: Includes forceps, scissors, and curettes for tissue handling and sample collection.
• Local Anesthetic: Administered to numb the area before the procedure.
• Sterile Drapes and Gloves: Maintain a sterile environment during the surgery.  

Goceng medical supplies the grounding pads and ESU pencil , which are the  essential component of electrosurgical procedures.  

Types of ESU Electrodes

1. Monopolar Electrodes:

   • Active Electrodes: These are used to deliver the electrical current to the target tissue.
     • Blade Electrode: A flat, blade-shaped electrode used for precise cutting.
     • Needle Electrode: A thin, needle-like electrode for fine cutting and pinpoint coagulation.
     • Ball Electrode: A rounded electrode used for coagulation.
     • Loop Electrode: Common in LEEP procedures for excising cervical tissue.
   • Dispersive (Grounding) Electrode: Completes the electrical circuit by returning the current from the patient to the ESU, ensuring patient safety.

2. Bipolar Electrodes:

   • Bipolar Forceps: Resembling tweezers, they have two tips that deliver and return the current, used for coagulating small blood vessels without the need for a grounding pad.
   • Bipolar Cutting and Coagulation Instruments: Specialized for both cutting and coagulation with precise control.

Electrosurgical Pencil, a hand-held device that holds the active electrode, allowing the surgeon to control the current delivery. 

• Cutting: Delivers a continuous waveform for sharp, precise cuts.
• Coagulation: Uses a pulsed or interrupted waveform to coagulate tissue and control bleeding.
• Blend: A combination of cutting and coagulation modes for simultaneous tissue cutting and bleeding control.

GOCENG medical grounding pads'  advantages: 

1. More uniform current distribution , unique hydrogel full coverage and edge coverage design makes the current flow distribution more uniform, and effectively protects the edge part to prevent the metal film from directly touching the patient.

2. No direction is required, compared with the ordinary grounding pad , the requirement of directivity is eliminated, Goceng's grounding pad can be pasted in any direction.

3. Smaller paste area, compared with the ordinary grounding pad  smaller area can also achieve the same performance, adapt to more paste parts.

4. Low heat, lower heat than ordinary grounding pad . 

5. Effectively eliminate the edge effect, the potential risk of scalding caused by the edge effect, resulting in the edge effect of the medical grounding pad , preventing the occurrence of scalding .
