The provided document is a Quick Reference Guide for the Olympus GuideSheath Kit 2, a single-use device identified by models K-401, K-402, K-403, and K-404. This kit is designed to facilitate endoscopic procedures by providing a guide sheath for the insertion of various EndoTherapy accessories and ultrasonic probes. The guide aims to provide essential steps for handling the kit, with a recommendation to consult the full instruction manual for detailed operating instructions.
Function Description
The GuideSheath Kit 2 serves as a conduit to guide EndoTherapy devices and ultrasonic probes during endoscopic procedures. Its primary function is to provide a stable and controlled pathway for these instruments, ensuring precise positioning and maneuverability within the body. The kit includes two types of stoppers: one specifically for ultrasonic probes (US stopper) and another for general EndoTherapy accessories (ET stopper). These stoppers are crucial for adjusting the protrusion of the device tips from the guide sheath, optimizing their functionality during different procedural steps.
Important Technical Specifications
The GuideSheath Kit 2 is available in four models, each compatible with specific channel diameters:
- K-401 and K-402: Compatible with channel diameters of 2.0 mm or more.
- K-403 and K-404: Compatible with channel diameters of 2.8 mm or more.
The kit includes different quantities and colors of stoppers depending on the model:
- K-401 (ET stopper): 4 pieces (White)
- K-402 (ET stopper): 3 pieces (White)
- K-403 (ET stopper): 4 pieces (3: Gray / 1: White)
- K-404 (ET stopper): 3 pieces (2: Gray / 1: White)
- All models (US stopper): 1 piece (Gray)
These specifications highlight the versatility of the kit, allowing it to be used with a range of endoscopes and accessories based on their channel size. The color coding of stoppers, particularly for the ET stoppers in K-403 and K-404, may indicate different functionalities or compatibility, though this is not explicitly detailed in the quick reference guide.
Usage Features
The GuideSheath Kit 2 is designed for ease of use, with clear instructions for preparing and attaching the stoppers.
Preparation of US Stopper:
- Insertion: The ultrasonic probe is inserted into the guide sheath's accessory port until its tip slightly protrudes from the guide sheath tip.
- Stopper Attachment: The US stopper is then attached to the ultrasonic probe by inserting the probe to the end of the slit on the stopper. A critical note emphasizes ensuring the probe reaches the end of the slit for proper fit.
- Securing: The US stopper's connection portion is pushed into the guide sheath's accessory port to secure it.
- Adjustment: The position of the US stopper is adjusted to ensure the probe tip protrudes slightly from the guide sheath tip. The guide also notes that the US stopper should be removed from the guide sheath's accessory port while it is attached to the ultrasonic probe.
Preparation of ET Stopper:
- Insertion: The EndoTherapy device is inserted into the guide sheath's accessory port so that its tip slightly protrudes from the guide sheath tip.
- Stopper Attachment: The ET stopper is attached to the EndoTherapy device by inserting the device to the end of the slit on the stopper. Similar to the US stopper, it's crucial to ensure the device reaches the end of the slit.
- Tip Adjustment: The guide provides "Tips" for adjusting the ET stopper's position to ensure the tip of various devices (Guiding device, Biopsy forceps, Cytology brush, Aspiration needle) protrudes appropriately from the guide sheath tip. This highlights the kit's compatibility with a broad range of EndoTherapy accessories.
Attachment of Stopper to the Guide Sheath:
- Initial Attachment: The ET stopper (with the EndoTherapy device or ultrasonic probe inside) is attached to the guide sheath.
- Insertion into Endoscope: The guide sheath, with the stopper attached, is then inserted into the endoscope.
- Positioning: Once the guide sheath reaches the target position, the stopper is moved along the guide sheath until it makes contact with the biopsy valve of the endoscope.
Important Usage Notes and Cautions:
- Combined Use: A critical note states that the guide sheath must not be inserted into the endoscope without being combined with an EndoTherapy accessory or ultrasonic probe. Failure to adhere to this could lead to bending or breaking of the guide sheath.
- Insertion Technique: When inserting the guide sheath, it should be held close to the biopsy valve and kept as straight as possible, then inserted gently into the endoscope.
- Endoscope Straightness: A "Caution" section emphasizes the importance of keeping the endoscope's insertion section near the control section as straight as possible. If this section is bent, it may be difficult to advance the EndoTherapy device into the guide sheath smoothly. Illustrations clearly show the correct (straight) and incorrect (bended) endoscope positions for insertion.
Maintenance Features
As a "Single Use Guide Sheath Kit," the device is not designed for maintenance, cleaning, or reprocessing. Its single-use nature implies that it should be disposed of after each procedure according to medical waste protocols. The guide does not provide any instructions for cleaning, sterilization, or repair, reinforcing its disposable characteristic. The focus is entirely on proper handling and usage during a single procedure.
