HEMORRHOID ABLATION SYSTEM

Hemorrhoid Ablation System

Mechanism of action

High-frequency current is delivered through the electrode into tissue, generating thermal energy that can produce coagulation, cauterization or ablation for therapeutic effect. Output intensity and duration can be adjusted according to tissue impedance to support controlled treatment. High-temperature heating at the electrode tip acts on the target tissue, producing necrosis, coagulation and carbonization in the tissue surrounding the electrode.

Indications

Internal hemorrhoids, the internal component of mixed hemorrhoids and varicose external hemorrhoids.

Procedure steps

Procedure step 1 — 01Inject local anesthetic into the fat of the ischiorectal fossa around the external anal sphincter outside the hemorrhoidal cushion.

Procedure step 2 — 02Insert an anoscope and inject tumescence-separation solution at the base of the hemorrhoid to separate the vascular and muscular layers.

Procedure step 3 — 03Insert the ablation-electrode tip into the hemorrhoid, activate RF energy and close the hemorrhoidal vessels.

Procedure step 4 — 04During the procedure, hemorrhoidal proteins denature and contract immediately; cool the treatment site with moist gauze.

Procedure step 5 — 05Over 3–14 days after the procedure, the hemorrhoid further contracts, is absorbed and resolves.

◎ Mild pain, limited bleeding and rapid effect　　◎ Fast recovery and low recurrence rate　　◎ Preserves anal-cushion function
