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.

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.

Electrosurgical knife - ITKnife2

Unique electrode design on the proximal side of the tip minimises invasiveness whilst maximising cutting versatility.

Electrosurgical hemostatic forceps - Coagrasper

Unique rotatable forceps construction provides more reliable, effective hemostasis no matter where the bleeding site is located.

Grasping forceps LA - EndoLifter

Acting like an extra hand to provide optimal lesion countertraction EndoLifter supports gastric ESD.

    Prevents the knife from slipping and also allows to hook up fibers - thereby facilitating a wide variety of cutting techniques during incision and dissection.
    * Dome-shaped cover :
    The rounded ceramic cover facilitates smooth & safe manipulation.
    * Injection port :
    A distal water exit allows saline to be injected through the sheath without replacing the device.
    * Sheath marking :
    Blue marking on the distal end helps improve the visibility of the sheath tip in the endoscopic field of view.
  • 2.0 mm Diameter Sheath - Slim sheath helps maintain suction capability in the scope channel while its rigidity supports smooth incision and tissue dissection.
