For Sclerotherapy and Endoscopic Needles, please proceed as follows
- Prepare a Luer-Lock adaptable syringe with the agent to be injected.
- Make sure that the needle is in its fully exposed position. Then attach the syringe to the needle via the Luer-Lock connection at the top of the handle and flush out the air in the piston using the liquid agent. Visually verify that the liquid agent reaches the distal tip of needle and all air has been evacuated from the inner catheter.
- Now retract the needle into its catheter to full withdrawn position. (The inner piston part of the handle is retracted to the position UP)
- Then introduce the catheter into the working channel of an appropriately sized endoscope. Advance in small increments until the catheter emerges from the scope.
- Fully deploy the needle until you feel the piston “click” into place. (The inner piston part of the handle is fully pushed into the outer part of the handle – Position DOWN)
- Proceed with the injection at an oblique angle to the tissue site.
- Following the injection(s), retract the needle until the needle piston “clicks” into the fully retracted position. (Position UP)
When using the irrigation flush port, the needle must be fully retracted until the piston “click” into the retracted position. Prepare a luer-lock adaptable syringe with the irrigation agent to be injected and attach the syringe to the irrigation flush port via the luer-lock protruding from the side of the lateral connection port.
When inserting or withdrawing device from scope, ensure that the distal end of the scope is not in the retroflexed position.
- Upon completion of the procedure, remove the instrument from the scope.
When the device is being advanced or withdrawn from the endoscope, it is important to ensure that the needle is in its fully retracted position to avoid damaging the working channel of the endoscope. (The inner piston part of the handle is retracted to the position UP)
