The system supports orthopedic trauma workflows involving large cannulated screw fixation, including femoral neck, tibial plateau, pelvic and iliosacral fixation, selected femoral fractures, and subtalar or ankle arthrodesis where compatible 6.5 mm implants are selected.

Guide-Wire Control, Cannulated Drilling and Screw Insertion Mechanism

The 6.5 mm system is organized around a 2.0 mm threaded guide-wire pathway that establishes the planned screw axis before larger instruments enter the bone. PS-026.36 combines a protection sleeve, drill sleeve, and guide-wire sleeve to create a controlled working channel while separating rotating instrumentation from surrounding soft tissue. Once the guide wire is positioned, the PS-026.12 4.5 mm cannulated drill advances over the wire so pilot-hole preparation remains referenced to the original trajectory; its limited block provides a mechanical depth-control element during drilling. PS-026.27 Cannulated Tap follows the same axial pathway when thread preparation is required for the selected 6.5 mm cancellous screw. The PS-026.15 cannulated countersink prepares the cortical entry region when the fixation technique requires accommodation of the screw head. Definitive insertion can then be performed with PS-026.42 Cannulated Screwdriver, which has a 3.5 mm hexagonal tip and passes over the retained guide wire. PS-026.30 provides a solid 3.5 mm hexagonal driver for compatible insertion, adjustment, or removal stages where guide-wire cannulation is no longer required.

Femoral Neck, Tibial Plateau and Pelvic Fixation Workflow

During 6.5 mm cannulated screw fixation, the set enters the procedure after fracture reduction or preparation of the intended fusion surfaces and determination of the planned screw trajectories. In femoral neck fixation, multiple 2.0 mm threaded guide wires can be positioned in a controlled parallel relationship before definitive screws are inserted, allowing the surgeon to establish the planned distribution within the femoral neck and head. The adjustable PS-026.39 parallel guide and PS-026.24 fixed 2.0 mm guide support reproducible wire spacing when more than one screw is required. Similar guide-wire-directed preparation is applicable during selected tibial plateau, pelvic, iliosacral, intercondylar femoral, and hindfoot fixation workflows using compatible large cannulated screws. Once wire position has been assessed according to the selected operative imaging protocol, the direct measuring device determines the required implant length. The 4.5 mm cannulated drill prepares the pathway, followed by the 6.5 mm tap when tapping is indicated. The cannulated 3.5 mm hex driver advances the screw while maintaining the established axis. After fixation, guide wires are removed and final screw length, position, joint penetration, reduction, and construct alignment are assessed according to the implant system technique.

2.0 mm Guide Wires, 4.5 mm Drill and Component Selection

Each PS-026 component addresses a specific stage of large cannulated screw fixation. PS-026.03 provides direct screw-length measurement after guide-wire placement. Four PS-026.06 2.0 mm threaded wires permit provisional trajectories, parallel fixation patterns, or replacement during the procedure. PS-026.39 provides an adjustable parallel-wire relationship, while PS-026.21 is the dedicated wrench used with that guide and PS-026.24 supplies a fixed parallel guide for 2.0 mm wires. PS-026.12 uses a 4.5 mm cannulated drilling diameter for preparation along the retained wire. PS-026.27 provides the corresponding 6.5 mm tapping function, while PS-026.15 supplies the cannulated countersinking stage. The 3.5 mm tip is represented in both PS-026.30 solid and PS-026.42 cannulated hexagonal screwdrivers, allowing the surgeon to select the driver according to whether the guide wire remains in place. PS-026.36 combines the protective outer working channel with dedicated drill and wire guidance. PS-026.33 Cleaning Stylet 2.0 mm is specifically relevant during reprocessing of narrow cannulated pathways. Across the listed quantities, the configuration contains 16 instruments or components across 13 instrument catalog references, plus the dedicated PS-026.000 container.

German Stainless Steel, Sterilization and Procurement Standards

The reusable instruments in the Cancellous Cannulated Screws 6.5mm Instruments Set are manufactured within Peak Surgicals’ German-forged stainless-steel platform for repeated orthopedic use, mechanical handling, cleaning, inspection, and sterilization. Cannulated fixation instrumentation requires detailed reprocessing because blood, marrow, bone particles, and irrigation residue can remain inside guide-wire lumens even when the external surface appears clean. The 2.0 mm cleaning stylet provides mechanical access through compatible narrow pathways, while the drill, tap, countersink, cannulated driver, parallel guides, and sleeve assembly require flushing and direct inspection. Drill cutting edges, tap threads, screwdriver tips, guide-wire surfaces, measurement markings, and adjustable guide interfaces should be examined for deformation, corrosion, retained debris, or functional wear before tray assembly. Unless otherwise designated, Peak Surgicals reusable instruments are supplied non-sterile and require cleaning and sterilization before first clinical use and following subsequent procedures according to the healthcare facility’s validated process. Peak Surgicals supports ISO 13485 certified manufacturing standards and CE-marked instrumentation. FDA procurement documentation should be managed according to applicable registration, listing, labeling, and quality requirements rather than interpreted as blanket individual device approval.

How does the 6.5mm Cannulated Screw Instrument Set differ from the 4.0mm Cannulated Cancellous Screw Set?
The Cancellous Cannulated Screws 6.5mm Instruments Set is configured around larger fixation hardware and correspondingly larger preparation instruments. The 6.5 mm configuration uses 2.0 mm threaded guide wires, a 4.5 mm cannulated drill, a 6.5 mm tap, and 3.5 mm hexagonal drivers. The 4.0 mm system uses a smaller 1.2 mm guide-wire pathway, 2.7 mm drill, 4.0 mm tap, and 2.5 mm driver interface. The 6.5 mm set also incorporates adjustable and fixed parallel guide-wire instrumentation, which is particularly relevant when multiple large cannulated screws must be positioned in a controlled relationship. Clinically, the larger system is suited to compatible large-bone fixation workflows such as femoral neck, tibial plateau, pelvic, and iliosacral procedures rather than the smaller-fragment emphasis of a 4.0 mm tray. The two systems therefore should not be interchanged because their guide wires, drilling diameters, taps, drivers, and intended screw dimensions are different.

How are the 2.0mm guide wire, 4.5mm drill and 6.5mm tap selected during fixation?
The 2.0 mm threaded guide wire establishes the intended trajectory before larger bone-preparation instruments are introduced. In femoral neck fixation, multiple wires can be positioned in parallel across the femoral neck toward the femoral head according to the selected screw construct. In tibial plateau or pelvic fixation, the wire similarly provides an axial reference for the planned large cannulated screw pathway. The 4.5 mm cannulated drill follows that wire to create the pilot channel while preserving the established direction. The 6.5 mm cannulated tap prepares the thread pathway when tapping is required by the implant system and bone condition. Screw length is determined with the direct measuring device before the compatible implant is advanced using the 3.5 mm hexagonal driver.

What do CE, ISO 13485 and FDA requirements mean when procuring this instrument set?
The Cancellous Cannulated Screws 6.5mm Instruments Set is supplied within Peak Surgicals’ medical-device manufacturing and procurement framework. ISO 13485 relates to the quality-management system used to control medical-device manufacturing processes. CE marking supports conformity requirements for applicable regulated markets. For United States procurement, FDA compliance concerns the applicable manufacturer registration, device listing, labeling, quality-system, and supporting regulatory documentation. FDA approved should not be used as a blanket description for each reusable orthopedic instrument unless that specific regulatory status applies to the individual device. Hospitals and distributors can retain the applicable compliance records with vendor qualification, purchasing, warranty, and reusable-instrument documentation.

How does the adjustable parallel guide control multiple guide-wire trajectories?
The PS-026.39 adjustable parallel guide allows multiple 2.0 mm guide wires to be positioned in a controlled spatial relationship rather than placing each trajectory independently. This is particularly relevant when a fixation construct requires more than one large cannulated screw, such as selected femoral neck or pelvic configurations. The surgeon establishes the reference wire and then adjusts the guide according to the required spacing before placing an additional parallel wire. PS-026.21 provides the dedicated wrench used with the adjustable guide mechanism. PS-026.24 supplies an additional parallel guide specifically for 2.0 mm wires, while the sleeve system controls passage through the soft-tissue corridor. These guiding components establish trajectory and spacing; definitive screw position still depends on the selected implant technique and appropriate intraoperative imaging.

How should hospitals clean and manage the complete 6.5mm cannulated screw set?
The Cancellous Cannulated Screws 6.5mm Instruments Set requires detailed lumen cleaning after each procedure because its drills, tap, countersink, screwdriver, guides, and sleeve components contain narrow pathways or recesses. Gross blood, bone, and marrow contamination should be removed promptly before residue dries within these internal surfaces. PS-026.33 Cleaning Stylet 2.0 mm can assist mechanical access through compatible cannulated passages, followed by the facility’s validated flushing, cleaning, rinsing, and drying process. Cutting surfaces, guide wires, adjustable mechanisms, hexagonal driver tips, measuring interfaces, and cannulations should then be inspected for wear, corrosion, deformation, or retained material. The instruments should be reconciled against their individual PS-026 catalog references before being returned to PS-026.000 Empty Container for sterilization and storage. Peak Surgicals provides a one-year limited warranty for manufacturing defects and eligible 30-day return support, while hospitals and distributors can request bulk or custom quotations for institutional purchasing.
