The Colwell TKA 5° Tibial Rasp Assembly is a complete assembly designed for compatible total knee arthroplasty (TKA) applications involving tibial preparation. The assembly combines four components: a rasp handle, rasp plate, T-handle canal rod, and handle grip. Its 15" (38.1 cm) overall length provides an extended instrument configuration, while the dedicated T-handle and grip support controlled handling during compatible surgical procedures.

The assembly incorporates a 5° tibial rasp configuration and a defined rasp plate measuring 2.65" (7.7 cm) in width and 1.75" (4.3 cm) in depth. The component-based construction provides a complete instrument setup rather than requiring the individual components to be sourced separately.

Design and Configuration

The Colwell TKA 5° Tibial Rasp Assembly consists of the following components:

• Rasp Handle: 15" (38.1 cm) overall length with a 3.625" (9.2 cm) handle section.
• Rasp Plate: 2.65" (7.7 cm) plate width and 1.75" (4.3 cm) plate depth.
• T-Handle Canal Rod: 15" (38.1 cm) overall length with a 4" (10.1 cm) T-handle width.
• Handle Grip: 4" (10.1 cm) overall length.

Together, these components form the complete tibial rasp assembly.

Tibial Rasp Configuration

The 5° configuration is incorporated into the assembly design for compatible TKA applications. The rasp plate provides the working surface of the assembly, while the extended handle and canal rod configuration provides the instrument's overall working reach.

Surgical Applications

The Colwell TKA 5° Tibial Rasp Assembly is designed for use in compatible total knee arthroplasty procedures where a tibial rasp assembly is required. Its configuration is intended for professional surgical environments and should be used according to the applicable surgical technique and instrument system requirements.

Handling and Use Considerations

The extended 15" (38.1 cm) configuration provides a substantial working length, while the 4" (10.1 cm) T-handle width offers a broad gripping area. The separate handle grip and rasp handle components form part of the complete assembly configuration.

Use should be limited to appropriately trained healthcare professionals following the applicable surgical technique, instrument instructions, and facility protocols.

Cleaning and Instrument Care

After use, the assembly should be cleaned according to the manufacturer's validated instrument-care instructions. Particular attention should be given to the interfaces and working areas of the rasp plate, handle, canal rod, and grip to ensure that visible soil and processing residues are removed.

Sterilization and Inspection

Before reuse, inspect the complete assembly for cleanliness, structural integrity, secure component interfaces, and any signs of wear or damage. Sterilization should be performed according to the applicable manufacturer's validated instructions and healthcare facility protocols.
