2200-13 Series: 5.5mm MIS Pedicle Screw Instrumentation with Persuader, Fixation Pins, and Torque Wrench

The 2200-13 series Spine Surgery Set is configured for minimally invasive posterior spinal surgery (MIS) using a 5.5mm rod system. The three MIS-specific instruments that distinguish this set from open surgery pedicle screw sets are the 5.5mm System Spinal Persuader and Persuader Sleeve, the four Fixation Pins (Ball-type and Pillar-type), and the 12 N.m Torque Wrench. In MIS percutaneous pedicle screw surgery, the rod is passed subcutaneously through the tissue between the percutaneous screw portals rather than under direct vision through an open wound. The Persuader and Sleeve engage the rod and the pedicle screw tulip head through the percutaneous portal and apply the force needed to seat the rod into the tulip — a manoeuvre that is impossible with a standard Rod Pusher when the rod and tulip are not directly visible. The Fixation Pins (Ball-type for ball-head set screws, Pillar-type for pillar-head tulips) provide provisional locking of each tulip-rod engagement after the Persuader seats the rod, holding the rod in position as the surgeon advances along the construct to the next screw level before final locking. The 12 N.m Torque Wrench ensures consistent calibrated final set screw tightening across all construct levels without relying on tactile judgment, which is particularly important in MIS where the tactile feedback from the percutaneous approach is reduced compared to open surgery.

Probe and Tap System: Double-Head Probe, Four Taps, and Pedicle Probes

The Double-Head Probe (2200-1301) combines straight and bent probe tips in a single instrument — the straight end is used for straight lumbar pedicle trajectories and the bent end for the angulated trajectories of thoracic pedicle screws and for angled lumbar approaches — eliminating the need to exchange instruments for the two probe geometries. The Single-Head Probe Straight (2200-1302) provides a dedicated straight probe for cases where the double-head instrument's ergonomics are not preferred. The AWL (2200-1334) establishes the cortical entry point before the probes advance through the pedicle. The four taps — φ4.5mm (2200-1303) for small thoracic pedicles, φ5.5mm (2200-1304) for standard lumbar, φ6.5mm (2200-1305) for large lumbar and L5-S1, and φ7.5mm (2200-1306) for the ilium and maximum-diameter applications — cover the complete pedicle screw diameter range for 5.5mm rod lumbar and thoracic fixation. The Pedicle Probe Straight (2200-1314) and Bent (2200-1315) perform post-tapping channel wall assessment. The T-Handle Quick Coupling (2200-1332) drives all quick-connect instruments.

Screwdrivers, Measurement, and Assembly Instruments

The Screwdriver for Polyaxial Screw (2200-1339) and Screwdriver for Monoaxial Screw (2200-1340) insert the two primary screw head designs. The Screwdriver T27 (2200-1316) drives T27 Torx set screws used in certain polyaxial tulip designs, and the Screw Nut Holder T27 (2200-1311) retains the T27 nut on the driver tip during introduction. The Straight Rechat Screwdriver (2200-1333) provides ratchet-handle set screw driving for continuous tightening without repeated repositioning. The Screw Measurement (2200-1322) measures the pedicle channel depth for screw length selection. The Crosslink Measurement (2200-1321) measures the rod-to-rod distance for crosslink connector length selection. The Mould Rod 200mm (2200-1307) is a malleable trial rod for measuring and recording the required definitive rod length and curvature before the definitive rod is contoured.

Rod Management, Compressor, Spreader, and Crosslink

The Rod Bender (2200-1335) contours the definitive rod. The Rod Holding Forcep (2200-1323) introduces the rod. The Rod Pushing Forcep (2200-1324) and Rod Pusher (2200-1336) advance the rod into successive tulip heads. The Rod Holder (2200-1338) stabilises the rod during the Persuader engagement step. The In-situ Bending Iron L (2200-1312) and R (2200-1313) adjust the seated rod in both sagittal directions. The Rod Twist (2200-1329) rotates the rod for coronal deformity correction. The Compressor (2200-1327) compresses adjacent levels along the seated rod. The Spreader (2200-1328) distracts adjacent levels. The Crosslink Screwdriver SW3.5 (2200-1308) and Crosslink Nut Holder SW3.5 (2200-1310) install the transverse crosslink. The Screw Cutter for Long Arm Screw (2200-1309) and Counter Torque for Screw Cutter (2200-1330) trim extended tulip arms.

Frequently Asked Questions

What procedures is this set used for?
The Spine Surgery Set 5.5mm Titanium Pedicle Screw is used for minimally invasive and open posterior pedicle screw-rod fixation of the lumbar and thoracic spine using a 5.5mm rod system. Primary indications include lumbar spinal fusion for degenerative disc disease with instability, lumbar and isthmic spondylolisthesis, thoracolumbar fracture stabilisation, and deformity correction. The four tap sizes (φ4.5–7.5mm) cover the full screw diameter range from small thoracic pedicles to iliac fixation. The MIS-specific Persuader, Fixation Pins, and Torque Wrench make this set appropriate for percutaneous minimally invasive surgery, while the probes, rod bender, compressor, spreader, and in-situ bending irons also support open posterior approaches.

How does this set (PS-OS-00300-11, $1,320.00) relate to the other 5.5mm pedicle screw sets on the same store?
This Spine Surgery Set (PS-OS-00300-11) uses the same 2200-13xx instrument series as the Spinal Pedicle Screw Set 5.5mm (PS-OS-00300-70, $1,815.00), also available from Peak Surgicals. Both share the 2200-13xx REF numbers, the 5.5mm Persuader and Sleeve, the four Fixation Pins, the 12 N.m Torque Wrench, and the Mould Rod. The PS-OS-00300-11 at $1,320.00 is $495 less than PS-OS-00300-70 at $1,815.00. Confirm instrument content directly with Peak Surgicals before ordering if you need to verify any configuration differences between the two SKUs at these price points.

What is the 5.5mm Persuader and why is it specific to MIS surgery?
The 5.5mm System Spinal Persuader (2200-1326) and Persuader Sleeve (2200-1325) are the instruments used to seat the rod into the pedicle screw tulip head during minimally invasive percutaneous surgery, where the rod and tulip are not accessible for direct open manipulation. In percutaneous MIS, the pedicle screws are placed through small stab incisions with the tulip heads protruding through the fascia, and the rod is passed subcutaneously through the tissue between the screw portals — the Persuader engages the rod through the percutaneous access tube and applies a controlled axially directed force to push the rod down into the tulip head against the elastic resistance of the soft tissue and the spring-loaded tulip, until the set screw can be engaged. Without the Persuader, seating the rod into each successive tulip head percutaneously is not possible with standard rod pushers. The 5.5mm designation indicates the Persuader is matched to the 5.5mm rod tulip geometry.

What are the four Fixation Pins and how are they used?
The four Fixation Pins — Ball-type ×2 (2200-1317, 2200-1318) and Pillar-type ×2 (2200-1319, 2200-1320) — are provisional rod-locking pins inserted into the set screw channel of the pedicle screw tulip after the rod is seated, before the definitive set screw is tightened. They hold the rod provisionally in the tulip while the Persuader is moved to the next screw level, preventing the already-seated levels from disengaging before the complete construct is assembled and the final set screws are tightened. The Ball-type pin engages set screw channels with ball-socket geometry and the Pillar-type engages channels with cylindrical geometry — two of each type are supplied to accommodate the two most common tulip designs and to provide a backup if one pin is dropped. The Insert Device for Fixation Pin (2200-1337) introduces the pins into the tulip channel through the percutaneous access portal.

What certifications does this set carry?
The Spine Surgery Set 5.5mm Titanium Pedicle Screw is manufactured under CE Mark, ISO 13485, and FDA compliant quality standards. ISO 13485 certification confirms Peak Surgicals operates a documented quality management system covering design control, material traceability, and manufacturing consistency for spinal surgical instruments. CE Mark confirms conformity with European medical device regulations, and FDA compliance supports procurement for US hospitals, spine surgery centers, and neurosurgical departments requiring verified regulatory documentation.
