ESD Devices

Contents start

Treatment with gastrointestinal endoscopy has evolved rapidly. From polypectomy to endoscopic mucosal resection (EMR), and now to endoscopic submucosal dissection (ESD), treatment has become both more effective and less invasive. With the remarkable ability to enable en-bloc resection of larger lesions, ESD clearly marks a major milestone in this evolution, offering an ideal substitute for open surgery.
Driving ESD innovation with unique forward-thinking concepts and proven reliability, only Olympus can offer you a total solution.

Key Features

Electrosurgical knife - DualKnife

Two different needle knife lengths are available. Each knife features easy two step knife adjustment (retracted and extended) for smooth and efficient cutting in all ESD applications.

Electrosurgical knife - DualKnife J

With the addition of a convenient jet, the new and evolved Dual Knife J will help you work and reduce the time it takes to perform an ESD procedure.

Electrosurgical knife - HookKnife

The distal L-shaped hook with rotation function for incision and dissection in longitudinal and lateral directions make it the safest knife in challenging situations such as fibrosis or colorectal ESD.

Electrosurgical Knife - HookKnife J

With the addition of a convenient jet, the new and evolved HookKnife J will help you work and reduce the time it takes to perform an ESD procedure.
