Intended Use

The MEDICON Spinal Spreading Systems are used to spread soft tissue and maintain surgical access in spine surgery and may only be used by surgeons with proper training and adequate experience in spine surgery.

Device Story

MEDICON Spinal Spreading Systems are reusable manual surgical instruments designed to spread soft tissue and maintain access during spine surgery. The system comprises various spreader models, including expandable frame-type retractors, ring-handle retractors, vertebral spreaders, and tubular retractors. These devices are used in clinical settings (OR) by trained spine surgeons. The instruments function mechanically to hold wound edges open or provide access for minimally invasive procedures. Components include blades, hooks, handles, and depth gauges. The system supports diverse approaches, including cervical, inter-laminar, trans-laminar, extra-foraminal, and dorsolateral. The device provides stable, self-retaining surgical access, which facilitates surgical visualization and procedural efficiency, potentially reducing operative time and improving patient outcomes by maintaining clear access to the surgical site.

Clinical Evidence

No clinical studies were performed. Substantial equivalence is supported by bench testing, including biocompatibility, cleaning validation (AAMI TIR30:2011), steam sterilization validation (ISO 17665-1:2006), and mechanical strength testing of blades and blade supports.

Technological Characteristics

Materials: Stainless steel (ASTM F899), Titanium alloy Ti-6Al-4V (ASTM F136), CP titanium (ASTM F67), Aluminum 6082 (EN 473-3), PEEK CA/CF 30, Polyphenylsulfone (ASTM D6394), Polypropylene (ASTM D4101), and Silicone. Mechanical operation via manual spreading mechanisms (expandable frames, ring handles, vertebral spreaders). Reusable, steam-sterilizable. Radiolucent components included.

Indications for Use

Indicated for use in spine surgery to spread soft tissue and maintain surgical access. For use by surgeons with proper training and experience in spine surgery.

| | Test to determine the strength of blade supports | Blade supports met acceptance criteria |
| | Test to determine the strength of blades | Blades met acceptance criteria |
| | Engineering analysis to determine strength testing worst case | Worst case was determined |
| Clinical Test<br>Summary: | No clinical studies were performed | |
| Conclusions:<br>Non-clinical<br>and Clinical: | Medicon considers the Spinal Spreading Systems to be equivalent to the<br>predicate devices listed above. This conclusion is based upon the devices'<br>similarities in principles of operation, technology, materials and indications for<br>use | |

#### 7. Substantial Equivalence

Substantial equivalence for the Medicon self-retaining retractors is based on similarities in intended use, design (function, dimensions and operational principles), materials, labeling and clearance letter.

#### 8. Conclusion

The minor differences between the Medicon Spinal Spreading Systems and the predicate devices of safety and effectiveness. Non-clinical testing demonstrates that the Medicon Systems do comply to relevant standards and they are equivalent to the predicate devices. Based on the comparison of technological characteristics and nonclinical testing the subject device is substantially equivalent to the predicate.
