Objectives

The primary objective of this tender is to procure high-quality, clinically compliant modular single knee axis joints equipped with a locking mechanism for provincial orthopaedic services. The procurement seeks to secure durable, safe prosthetic components that meet precise engineering standards while supporting government transformation goals through preferential procurement policies.

Scope

The tender covers a one-off supply and delivery contract for 150 units of modular single knee axis joints with a locking option. Deliveries must be made to designated provincial health facilities. The scope includes provision of all necessary product documentation, warranty support, and compliance verification through mandatory physical sample submissions prior to the closing date. Evaluation follows a strict three-stage process: administrative compliance, sample verification against specifications, and final scoring based on price and preference points.

Technical Requirements

• Construction & Materials: Manufactured from stainless steel with roller bearings in the knee axis bushing to ensure smooth articulation.
• Connections: Features pyramid adaptors for both proximal and distal interfaces.
• Locking Mechanism: Engages automatically at full extension with assistance from an extension spring. Controlled via a plastic/nylon handle with a vertical slot, secured using a 3.6mm chrome-plated brass or stainless steel screw.
• Dimensions & Weight: Maximum weight of 700 grams; height between 35mm and 38mm (knee centre to upper pyramid edge); total length strictly between 108mm and 110mm.
• Performance Metrics: 120° flexion angle; rated for a maximum patient body weight of 125 kg.
• Accessories: Includes a 2mm Perlon cord lock cable attached via threaded fittings and 3.6mm screws on either side of the joint.
• Quality & Certification: Must hold a C.E. rating, provide a two-year replacement warranty, and demonstrate high-grade machining free from sharp edges or substandard materials.
• Verification: Physical samples must be delivered by the closing date for direct specification matching and identification.

Skills Requirements

This tender does not mandate specific professional qualifications or licensed personnel. Instead, bidders must demonstrate robust manufacturing or supply chain capabilities, including precision machining expertise, quality assurance protocols, and logistical competence to meet strict dimensional tolerances and delivery timelines. Suppliers must also possess the administrative capacity to compile complete returnable documents, maintain active Central Supplier Database registration, and provide valid tax clearance certificates.

Notable Terms and Explanations

• H.D Designation: Indicates a heavy-duty configuration engineered for enhanced load tolerance and durability in clinical settings.
• Pyramid Adaptors: Standardized prosthetic limb mounting interfaces that ensure universal compatibility with existing orthopaedic frameworks and socket systems.
• Perlon Cord: A high-tensile synthetic nylon rope commonly used in prosthetics for reliable mechanical locking and tension adjustment.
• C.E. Rating: Conformité Européenne certification confirming compliance with European health, safety, and environmental protection standards for medical devices.
• 80/20 Preference System: A procurement scoring model allocating 80 points to competitive pricing and 20 points to companies with 100% Black African ownership, in line with national transformation regulations.
• Sample Submission Mandate: Bidders must physically submit product samples before the closing deadline. Failure to do so results in automatic disqualification, as samples are evaluated against exact technical specifications.
