A 4.0mm Cannulated Screw Instrument Set is a complete stainless steel surgical instrument kit used in trauma and orthopedic surgery to place cannulated screws over a guide wire. The set includes the guide pins, drills, taps, depth gauge, screwdrivers, and sleeves needed to prepare, measure, and place 4.0mm cannulated screws with precision, and it ships in a perforated sterilisation case ready for autoclave processing.
What Is a Cannulated Screw Instrument Set Used For?
Cannulated screw instrumentation is used in trauma surgery whenever a screw needs to be inserted along a pre-placed guide wire rather than free-hand. Because every instrument in the set from the drill bit to the tap to the screwdriver has a hollow core, the surgeon can slide each tool over the same guide wire in sequence. This keeps the screw trajectory accurate throughout drilling, tapping, and screw placement.
Common use cases include:
- Fixation of femoral neck fractures
- Scaphoid and small bone fracture fixation
- Ankle and tibial fracture fixation
- Percutaneous minimally invasive screw placement
- General orthopedic and trauma reconstruction procedures
Key Features of the 4.0mm Cannulated Screw Instrument Set
Full Procedural Workflow in One Kit
The set covers the entire cannulated screw workflow guide wire placement, depth measurement, drilling, countersinking, tapping, and screw driving so surgical teams do not need to source instruments separately.
Hollow (Cannulated) Instrument Design
Every functional instrument (drill bit, tap, countersink, screwdrivers) is cannulated, allowing it to pass directly over the guide wire for consistent alignment and reduced risk of screw malposition.
Surgical-Grade Stainless Steel Construction
All instruments are manufactured from medical-grade stainless steel for corrosion resistance, durability, and repeated autoclave sterilisation cycles.
Colour-Coded, Ergonomic Handles
The hex screwdriver and hollow hex screwdriver feature blue ergonomic handles for a secure grip and quick visual identification during procedures.
Autoclavable Sterilisation Case
The kit is housed in a perforated stainless steel sterilisation tray with a locking latch, sized to fit standard autoclave and sterile processing workflows.

Frequently Asked Questions
What screw size does this instrument set support?Â
This set is designed specifically for 4.0mm cannulated screws, with all drill bits, taps, and countersinks sized to match.
What material is the instrument set made from?Â
Every instrument and the sterilisation case are made from surgical-grade stainless steel, which resists corrosion and withstands repeated autoclave sterilisation.
Does the set include a sterilisation case?Â
Yes. The set ships in a perforated stainless steel sterilisation case measuring 295mm x 200mm x 75mm, with a locking latch for secure closure during handling and sterilisation.
How many guide pins are included?Â
The set includes 4 threaded guide pins (ø1.2 x 150mm) for screw placement and 1 cleaning guide pin (ø1.2 x 200mm) for instrument maintenance.
What is the purpose of the cannulated design?Â
Cannulated instruments have a hollow core so they can be passed directly over a pre-placed guide wire. This keeps the drill, tap, countersink, and screwdriver aligned along the same trajectory throughout the procedure.
What procedures is this instrument set used for?Â
It is commonly used in trauma and orthopedic surgery for fracture fixation, including femoral neck, tibial, ankle, and small bone fractures requiring cannulated screw placement.
Can this set be sterilised and reused?Â
Yes. All components are manufactured from stainless steel and fit standard autoclave sterilisation for reuse across multiple procedures, subject to your facility’s sterilisation protocols.
What is included besides the drilling and tapping instruments?Â
The set also includes a depth gauge for measuring screw length, a nail holder sleeve, a limiting wrench, and both a hollow hex screwdriver and a standard hex screwdriver for screw insertion
