U-Shaped Open-End Instrument Stringer 15 × 7 cm

U-shaped open-end stringer for hinged surgical instruments

The Mediwish ISU157 is a reusable U-shaped open-end instrument stringer designed to hold compatible ring-handled surgical instruments in an open and unlocked position during cleaning, preparation and sterilization workflows. Its compact 15 × 7 cm (6 × 2.75 in) format is suitable for organizing small groups of instruments in compatible baskets, trays and instrument sets.

The two parallel arms are passed through the finger rings of compatible forceps, clamps, scissors, needle holders and similar hinged instruments. This separates the handles and helps keep joints and working ends open for access during reprocessing.

Key features

• Open U-shaped construction: enables quick loading and removal of compatible ring-handled instruments.
• 304 stainless steel: durable and corrosion-resistant material for reusable sterile-processing accessories.
• Compact dimensions: 15 × 7 cm (6 × 2.75 in).
• Open and unlocked positioning: helps prevent hinged instruments from closing during processing.
• Instrument organization: keeps selected instruments grouped within a compatible tray or basket.
• No locking bar: simple open-end design for workflows where a closure is not required.

Technical specifications

Typical applications

The stringer can be used with compatible hemostatic forceps, surgical clamps, scissors, needle holders and other hinged instruments with two finger rings. Actual capacity depends on the dimensions and thickness of the instruments and the spacing required by the facility’s validated process.

Recommended use

1. Inspect the stringer for bending, cracks, corrosion, rough surfaces or other damage.
2. Prepare and open each instrument according to its manufacturer’s instructions.
3. Pass one stringer arm through each row of finger rings so that the instruments remain open and unlocked.
4. Distribute the instruments without overcrowding or compressing their joints and working ends.
5. Place the complete assembly in a compatible basket, tray or packaging system.
6. Clean, inspect, package and sterilize according to the validated facility procedure and the instructions for all instruments and equipment involved.

Important handling information

• The stringer is an organizing accessory and does not itself clean, disinfect or sterilize instruments.
• Because this model has open ends and no locking bar, support it in a suitable basket or tray during movement and processing.
• Do not overload the stringer or allow instruments to obstruct cleaning action, drainage or sterilant contact.
• Confirm compatibility with the instruments, chemicals, equipment, packaging and sterilization cycle before use.
• Remove the stringer from service if it becomes bent, damaged, corroded or difficult to clean.
