Gyrus Acmi GY5-CFH USA Series Continuous Flow Hysteroscope 5.5mm 3Fr Channel

Gyrus ACMI | Continuous Flow Hysteroscope Sheath Assembly | 5.5 mm Profile | GY5-CFH

The Gyrus ACMI GY5-CFH is a high-performance, medical-grade continuous flow hysteroscope sheath assembly designed for diagnostic and therapeutic interventions within the uterine cavity. Functioning as a critical outer framework for rigid optical endoscopes, this USA Series sheath system features a dual-lumen continuous flow channel architecture. This design allows for the simultaneous introduction of distension fluids (such as saline or glycine) and the continuous evacuation of debris, mucus, and blood from the operative field.

By maintaining a balanced hydrodynamic flow, the GY5-CFH ensures a clear, unobstructed visual path for the surgeon. It also features a dedicated 3 French (3 Fr) auxiliary operating channel, which accommodates flexible or semi-rigid micro-instruments—such as biopsy forceps, scissors, or regular electrosurgical electrodes—enabling immediate tissue harvesting or targeted pathology ablation under direct visualization.
