Percutaneous Guiding System

The Percutaneous Guiding System is a set of instruments that allows percutaneous placement of long screws in the pelvic area and other body regions. It allows easy and accurate drilling and screw insertion.

The Percutaneous Guiding Instrument protects the soft tissues and guides Drill Bits, Screwdriver and Screw to the bone and can be secured to the bone with a K-Wire. A bullet nose eases insertion of the guide. The slender shape of the guide protects the soft tissue. The V-shape gives sufficient control to the Drill Bit and guides the screw to the drilled hole. It allows greater flexibility than the tubular drill sleeves. The use of oscillating drills is recommended. A K-Wire hole allows K-Wire fixation of the guide to the bony surface. The instrument is 220 mm long.

Screwdriver, diameter 2.5 mm, self-holding

The extra long self-holding Screwdriver is especially designed for using 3.5 mm Pelvic Cortex Screws. This combination also helps apply percutaneous screws in other body regions.

The set also contains a Cleaning Brush for the K-Wire hole, a Sterilizing Tray, an Insert for Screws and a Lid to enable proper storage of the instruments.

Technique:

1. Define the entry point of the screw and perform a stab incision.

2. Insert the percutaneous guiding instrument and bring it in direct contact with the bone surface.

3. Fix the percutaneous guiding instrument by inserting a 2.0 mm K-wire, length 280 mm, through the cannulation.

4. Pre-drill the hole with the calibrated 2.5 mm drill bit over the V-shaped channel ofthe percutaneous guiding instrument.

5. Use the self-retaining screwdriver 2.5 to insert and tighten a self-tapping 3.5 mm pelvic cortex screw.

6. Remove the percutaneous guiding instrument and the K-wire.
