Vessel Sealing and TURP: What Flagship ESU Modes Do

Electrosurgery · DS.Med editorial

Two functions separate flagship generators from the mid-range: controlled vessel sealing and resection in liquid medium. Both replace what used to require separate devices — or separate operating time.

Seal: the suture-free ligature

Seal mode compresses the vessel between bipolar jaws and applies energy in feedback-controlled pulses until collagen and elastin fuse into a permanent seal. The unit confirms the weld automatically. Vessels and tissue bundles up to 7 mm are ligated in seconds — no suture material, no knots, a dry field. Hysterectomy, colectomy and thyroid surgery gain minutes on every pedicle.

TURP: energy under irrigation

Transurethral resection works inside a fluid-filled cavity, where ordinary monopolar settings lose energy into the irrigant. The TURP mode adapts output for stable cutting and coagulation in liquid medium — the basis of prostate resection and hysteroresectoscopy.

In the DS.Surg line both functions live in the Prime Pro flagship: one generator covers open, laparoscopic and transurethral surgery.

Frequently asked questions

How reliable is a Seal ligature compared to a suture?
A correctly executed seal withstands supraphysiological pressures; the unit verifies each weld and signals if it is incomplete.
Does TURP mode need special electrodes?
Yes — resectoscope loop electrodes designed for work in irrigation fluid; the generator adapts output automatically.
Who needs a flagship like Prime Pro?
Departments combining open surgery with urology or gynecology endoscopy — one platform replaces several specialized generators.
