Additional Working Channel Solution

Traditional single-channel flexible endoscopes have only one working channel, making simultaneous dual-instrument coordination impossible during procedures. The lack of tissue retraction and counter-traction support significantly increases the difficulty and reduces the precision of demanding mucosal resection procedures such as ESD and EMR.

With single-channel endoscopes, instruments must be frequently exchanged in and out during the procedure, resulting in cumbersome workflows and prolonged operative time, substantially reducing overall surgical efficiency.

Conventional endoscopes lack angle-adjustment assist structures, leaving instrument output angles fixed. When faced with curved, concealed, or complex lesion sites, surgical field exposure is limited and instrument maneuverability is insufficient, making it difficult to accommodate complex endoscopic procedures.

This product is intended for use with flexible endoscopes during endoscopic procedures to guide instruments into the luminal tract. Primary procedures include:

Endoscopic mucosal resection (EMR)

Endoscopic submucosal dissection (ESD)

Clip deployment and retrieval

Management of gastrointestinal bleeding

Other endoscopic procedures requiring an auxiliary working channel

Integrated Design for Clear, Unobstructed Visualization– The transparent cap is integrated with the additional working channel, ensuring a clear, wide field of view during procedures. The independent external channel accommodates two instruments simultaneously, effectively improving procedural efficiency.

270° Full Rotation for Complex Anatomies– The transparent tip rotates freely 270° in both directions, allowing flexible multi-angle instrument positioning to readily address a variety of complex procedures.

Multi-Function Channel for Broad Application– The additional channel supports both suction and irrigation functions. It is compatible with EMR, ESD, and a full range of endoscopic mucosal resection procedures, offering versatile clinical applications.

This product directly addresses the clinical limitations of traditional single-channel flexible endoscopes, including single-instrument operation, lack of auxiliary retraction channels, absence of independent suction and irrigation pathways, and difficulty in managing complex lesions. It eliminates the need for expensive multi-channel endoscopes, enabling bimanual coordinated operation with conventional gastrointestinal endoscopes and reducing equipment procurement costs for the department.

The 270° rotatable transparent cap provides multi-angle exposure of concealed lesions and delivers sustained tissue tension during demanding procedures such as ESD, shortening the learning curve and reducing operative time. The independent channel enables simultaneous suction and irrigation, eliminating frequent instrument exchanges and substantially reducing intraoperative interruptions.

The integrated assembly is easy to install and remove, securely fixed without slippage, and does not scratch the endoscope shaft. It offers broad device compatibility and covers a full range of gastrointestinal endoscopic procedures, including polypectomy, early cancer dissection, hemostasis, and clip removal. This provides a low-cost, easily adoptable standardized dual-channel endoscopic assist solution for endoscopy units across all levels of healthcare institutions.
