Large Fragment Instruments Set – 3.2/4.5mm Drilling & 4.5/6.5mm Tapping

Large Fragment Instruments Set, SKU PS-OP-4158, is a reusable orthopedic fracture-fixation instrumentation system manufactured in German stainless steel and configured around the PS010A large-fragment screw workflow. The set contains a 3.2mm x 130mm quick-coupling drill bit, 4.5mm x 130mm quick-coupling drill bit, countersink for 4.5mm and 6.5mm screws, T-type quick-coupling handle, 4.5mm cortex-screw bone tap, 6.5mm cancellous-screw bone tap, 4.5/3.2mm insert drill sleeve, combined 3.2/4.5mm and 3.2/6.5mm drill-and-tap sleeves, 3.5mm screwdriver shaft, 3.5mm hexagonal screwdriver with sleeve, depth gauge, sharp hook, large neutral and loaded drill guide, pointed drill guide, large plate bender and empty container. The system supports orthopedic trauma surgeons performing open reduction and internal fixation with large-fragment plates and 4.5mm cortex or 6.5mm cancellous screws in long-bone fracture surgery. It is suited to trauma hospitals, orthopedic operating rooms, fracture-fixation centers and surgical distributors requiring dedicated drilling, tapping, countersinking, measurement, plate contouring and screw insertion instrumentation.

Drilling, Tapping and Screw Preparation Geometry

The PS010A configuration follows the mechanical sequence used to prepare bone for large-fragment screw fixation. The 3.2mm x 130mm drill bit creates the pilot hole associated with the 4.5mm cortex-screw pathway, while the 4.5mm x 130mm drill bit supports the larger preparation required for compatible 6.5mm cancellous-screw fixation. The combined drill-and-tap sleeves maintain a defined relationship between the drill, tap and operative site, with the 3.2/4.5mm sleeve corresponding to cortex-screw preparation and the 3.2/6.5mm sleeve supporting cancellous-screw preparation. The dedicated 4.5mm cortex bone tap cuts the appropriate thread pathway in cortical bone, while the 6.5mm cancellous bone tap prepares the compatible cancellous-screw trajectory. The countersink creates the screw-head seating geometry for compatible 4.5mm and 6.5mm screws with an 8.0mm head. The large neutral and loaded drill guide provides controlled drilling positions for plate holes, while the pointed drill guide assists targeted drilling where point contact is required. The 3.5mm screwdriver shaft and hexagonal screwdriver transfer rotational force to compatible screw interfaces. The T-type quick-coupling handle provides manual control of compatible shafts and taps during preparation and fixation.

Large-Fragment Plate Fixation Workflow

The set is intended for open reduction and internal fixation procedures involving large-fragment plate constructs on long bones and other skeletal sites treated with compatible 4.5mm and 6.5mm fixation. After fracture exposure and reduction, the large plate is positioned against the bone and maintained in the desired contour with the Large Plate Bender where compatible plate shaping is required. The Large Neutral & Loaded Drill Guide establishes the selected drilling mode through the plate, while the Pointed Drill Guide provides localized drill positioning. For 4.5mm cortex screws, the 3.2mm drill bit establishes the pilot channel, followed by the 4.5mm cortex bone tap when tapping is required. For 6.5mm cancellous screws, the 4.5mm drill and corresponding 6.5mm cancellous tap prepare the compatible pathway. The Depth Gauge measures prepared screw depth before selection of the appropriate implant length. The Countersink prepares the screw-head seat where required by the fixation construct. The 3.5mm screwdriver shaft or hexagonal screwdriver then engages the compatible screw interface for insertion. The T-type quick-coupling handle provides manual control during drilling, tapping and screw placement, while the pointed guide and sharp hook assist with localized instrument positioning and operative manipulation.

The 260.320 3.2mm x 130mm drill bit and 260.450 4.5mm x 130mm drill bit provide the two primary drilling diameters. The 305.030 countersink prepares 4.5mm and 6.5mm screw seats, while 264.040 and 264.050 provide dedicated taps for cortex and cancellous screw preparation. The 307.095 insert sleeve and combined 307.070 and 307.080 drill-and-tap sleeves control instrument alignment. The 301.070 screwdriver shaft and 301.031 hexagonal screwdriver provide screw insertion interfaces. The 303.020 depth gauge determines screw length, the 371.000 sharp hook supports controlled manipulation, and the 304.020 and 308.000 drill guides establish drilling trajectories. The 302.020 large plate bender is supplied as a pair for compatible plate contouring. The 900.048 empty container provides organized storage. Optional instruments listed separately on the product page include additional drill bits, countersinks, quick-coupling handles and adapters, T-handle bone taps, screwdrivers, drill and tap sleeves, bending presses, reconstruction-plate benders, screw-holding forceps, roller-type bending pliers and a hollow mill for removal of large 4.5mm and 6.5mm screws.

German Stainless Steel, Reprocessing and Procurement

The Large Fragment Instruments Set is configured as reusable orthopedic instrumentation for repeated cleaning, inspection, handling and sterilization in professional surgical environments. German stainless steel provides the mechanical substrate for drill bits, bone taps, sleeves, guides, screwdrivers and plate-bending instruments exposed to controlled mechanical loading during fracture fixation. Reprocessing should follow the healthcare facility's validated workflow, including point-of-use cleaning, decontamination, inspection, drying, packaging and sterilization according to applicable manufacturer instructions. Steam autoclave sterilization is appropriate for compatible reusable stainless steel components when performed under a validated cycle. The supplied empty container organizes the PS010A instrumentation for storage, transport and sterile-processing preparation. Peak Surgicals supports medical procurement with CE marking and ISO 13485 quality-management certification, together with FDA-compliant procurement support for applicable healthcare markets. The current product page lists the set at $1,062.15 USD and identifies it as a large-fragment orthopedic instrumentation configuration. The core set can be procured as a complete configuration, while the separately listed optional instruments allow procurement teams to expand the system for additional drilling, tapping, plate-bending, screw-holding and screw-removal requirements.

Large Fragment Instruments Set

Details of Large Fragment Instruments Set is Given Below.

How does the Large Fragment Instruments Set differ from a small-fragment instrument set?
The Large Fragment Instruments Set is configured around 4.5mm cortex and 6.5mm cancellous screw preparation. Its principal drill diameters are 3.2mm and 4.5mm, with dedicated taps and sleeves for the corresponding screw pathways. A small-fragment set uses smaller drilling, tapping and screw interfaces for smaller plates and screws. The PS010A configuration also includes a large plate bender designed for compatible large-fragment plates. Its depth gauge is specifically marked for 4.5mm and 6.5mm screws. The instrumentation therefore matches the larger implant dimensions and preparation sequence used in large-fragment fixation.

When is the 3.2mm drill used instead of the 4.5mm drill?
The 3.2mm drill bit is used for the pilot preparation associated with compatible 4.5mm cortex screws. The 4.5mm drill bit provides the larger preparation required for compatible 6.5mm cancellous-screw fixation. The combined 3.2/4.5mm and 3.2/6.5mm sleeves help maintain the appropriate drilling and tapping relationship. The 4.5mm cortex tap prepares the threaded pathway where tapping is required. The 6.5mm cancellous tap provides the corresponding preparation for compatible cancellous screws. Final instrument selection follows the plate and screw system used for the fracture construct.

What do CE, ISO 13485 and FDA procurement support mean for this set?
The Large Fragment Instruments Set is supplied within Peak Surgicals' medical-device quality and procurement framework. CE marking addresses applicable European conformity requirements. ISO 13485 relates to the manufacturer's medical-device quality-management system. FDA-compliant procurement support is relevant to applicable US healthcare purchasing workflows. Hospitals and distributors can use the associated documentation during supplier qualification and procurement review. Product and regulatory records should be retained according to the purchasing institution's requirements.

How do the drill guides, sleeves and quick-coupling handle function during fixation?
The Large Neutral & Loaded Drill Guide controls drill positioning according to the selected plate-hole preparation technique. The Pointed Drill Guide provides a pointed contact interface for controlled placement over the selected drilling location. The 4.5/3.2mm insert sleeve guides the 4.5mm drill and 3.2mm pilot pathway relationship. The combined 3.2/4.5mm and 3.2/6.5mm drill-and-tap sleeves maintain alignment between drilling and tapping instruments. The T-type Quick Coupling Handle accepts compatible instruments and transfers manual rotational force. Together these components establish the controlled mechanical pathway required for large-fragment screw preparation.

Is the Large Fragment Instruments Set suitable for hospital sterilization and procurement?
The Large Fragment Instruments Set is configured as reusable orthopedic instrumentation for professional surgical use. Components should undergo cleaning, inspection, drying, packaging and validated sterilization according to the healthcare facility's reprocessing protocol and applicable manufacturer instructions. Steam autoclaving is used for compatible reusable stainless steel components under a validated cycle. The Empty Container provides organized storage for the supplied PS010A instrumentation. Optional instruments listed on the product page can be purchased separately when additional drilling, tapping, plate-bending or screw-removal capability is required.
