Basic Operation of the Coagrasper™ Device
1 Push the slider to open the cups.
2 Rotate the entire handle to adjust the orientation of the grasping forceps (clockwise rotation is smoother than counterclockwise rotation).
3 Guide the grasping forceps to the target region and grasp it. Lift the grasped tissue gently and supply high-frequency current.
Applicable forceps channel diameters
The Coagrasper™ device for upper gastrointestinal applications (FD-410LR) can be used with a scope that has a channel diameter of 2.8 mm or more. The Coagrasper™ device for colorectal use (FD-411UR) should be used with a scope that has a channel diameter of 3.2 mm or more.
Why the applicable channel diameters are different
The Coagrasper™ device for colorectal use (FD-411UR) has a long working length. When it is inserted into a colonoscope while it is angulated, heavy pressure applied to the proximal end will cause deflection of the sheath. To prevent this, the proximal end of the sheath is coated with a reinforcing sheath, which increases the outer diameter of this part of the Coagrasper™ device.
