With the rapid advancement of minimally invasive surgery and endoscopic techniques, argon plasma coagulation (APC) and electrosurgical units (ESU), as two core energy-based devices, are widely used in surgical hemostasis, tissue cutting, and related fields. However, many users remain confused about their differences. Simon Medical provides an in-depth analysis of their distinctions—from technical principles and clinical scenarios to practical outcomes—empowering clinicians to make precise decisions, enhance surgical safety, and improve procedural efficiency.

I. Technical Principles: Fundamental Differences in Energy Delivery Methods

Electrosurgical Unit (ESU):

Direct Contact & Current-Based Cutting: Operates through direct contact between the electrode and tissue, utilizing high-frequency electrical current to generate localized heat for tissue cutting or pinpoint coagulation.

Adjustable Depth of Action: Depth of tissue effect can be controlled via power settings, enabling deep tissue applications (e.g., tumor resection) or superficial hemostasis.

Argon Plasma Coagulation (APC)

Non-Contact Plasma Energy Transfer: Uses ionized argon gas to create a conductive plasma arc, delivering energy to tissue without direct physical contact.

Diffused Thermal Effect: Achieves homogeneous superficial coagulation through evenly distributed thermal energy, ideal for controlling bleeding across broad or uneven surfaces.

Argon Plasma Coagulation (APC):

Non-Contact, Gas-Mediated Energy Transfer: Ionized argon gas generates a plasma beam, which is delivered via a gas jet to uniformly transfer energy to the tissue surface without direct contact.

Superficial Coagulation: Energy acts only on the superficial tissue layer, minimizing deeper thermal damage.

Summary:

ESU: "Hard Contact" – Ideal for precise cutting and targeted coagulation (e.g., tumor resection, focused hemostasis).

APC: "Soft Coverage" – Optimized for diffuse hemostasis and superficial tissue treatment (e.g., broad bleeding surfaces, mucosal ablation).

II. Clinical Applications: Scenario-Driven Selection

Typical Clinical Scenarios:

ESU: Simultaneous cutting and coagulation during cholecystectomy (gallbladder removal), enabling precise tissue dissection with immediate hemostasis.

APC: Rapid, non-contact hemostasis over broad resection surfaces after intestinal polypectomy, minimizing thermal damage to surrounding tissues.

III. How to Choose? Simon Medical’s Guidance for Optimal Selection

Needs-Based Selection Principles

Require cutting capability or deep tissue intervention? → Choose ESU (e.g., tumor resection, precise coagulation in narrow fields).

Need broad superficial hemostasis or endoscopic compatibility? → Choose APC (e.g., mucosal ablation, diffuse bleeding control in confined spaces).

Combined Application Scenarios
For complex procedures, leveraging both technologies maximizes outcomes:

Example: In liver cancer resection, ESU precisely excises the tumor, while APC swiftly coagulates oozing blood across the raw hepatic surface, reducing operative time and complications.
