TraCloser endoscopic tissue traction device

Product Overview

TraCloser™ provides tissue traction and supports defect closure during endoscopic procedures such as endoscopic submucosal dissection (ESD) — available in Articulated Basic Gripper G, Articulated Dual Gripper G, and Retractable types.

Built to Work with ROBOPERA™

TraCloser™ mounts on a conventional endoscope and is driven by the ROBOPERA™ controller — one integrated, robot-assisted endoscopy setup.

Conventional endoscope fitted with the ROBOPERA controller, with a TraCloser device at the distal tip — Endoscope + ROBOPERA™ controller + TraCloser™ at the tip

ROBOPERA installed on a standard endoscopy trolley — ROBOPERA™ installed on a standard endoscopy trolley

Type 01

Articulated Basic Gripper G

Four-joint articulation for wider-range control and precise traction in challenging anatomy.

FDA 510(k) Cleared

Enhanced multi-angle controlFour-joint articulation (grip, wrist, arm, roll) enables precise angulation and a wide range of motion for challenging lesions.
Multi-angle forceps for dynamic tractionForceps open and close within a 180° up-and-down range, enabling multi-angle tissue manipulation.
Secure traction & stable tissue handlingA wide jaw opening and length securely grasp deep and wide tissue.

Application areas: Esophagus, Stomach, Colon, Rectum

Overtube: Required

Type 02

Articulated Dual Gripper G

A versatile 2-in-1 solution for precision traction that supports efficient defect closure.

FDA 510(k) Cleared

2-in-1 functionality for ESDCombines tissue traction and defect closure support in a single device, streamlining the procedure.
Traction for large-lesion approximationTwo independent jaws, a fixed central jaw, and roll-arm articulation enable approximation of large lesions and optimal positioning to support closure via clipping.
Supports efficient defect closureEnables secure defect closure through large-lesion approximation and optimal positioning.

Application areas: Esophagus, Stomach, Colon, Rectum

Overtube: Required

Type 03

Retractable

Concealed traction mechanism for secure and precise operation during endoscopic procedures.

FDA 510(k) — clearance in progress

Precise tissue manipulation with controlled tractionSmooth advancement / conceal motions to pull or push tissue into position for effective, precise dissection — even while lifting a flap.
Safe use in confined spacesA concealed traction mechanism allows secure operation while minimizing interference with the endoscopic field.
Overtube-free designA compact retracted profile is optimized for use in the proximal colon and esophagus without requiring an overtube.

Application areas: Esophagus, Stomach, Colon, Rectum

Overtube: Not required
