I. Core Components & FunctionsThe 5.5 Orthopedic Instrument Set is designed for posterior spinal fixation surgery, primarily for fixation, fusion, and deformity correction of the thoracolumbar and cervical spine. Key instruments include:
- Pedicle Preparation Tools: Awls, bone probes, starter cones, and taps for establishing pedicle screw pathways.
- Implant Manipulation Instruments: Rod holders, compression/distraction forceps, and rod benders for adjusting rod positioning and tension.
- Auxiliary Tools: Quick-connect handles, impactors, screw breakers, and sleeves to enhance operational efficiency.
- Measurement & Positioning: Bone locators, depth gauges, and trial rods to ensure precise implant placement.
II. Surgical Applications- Spinal Deformity Correction: Scoliosis correction, kyphosis reconstruction.
- Posterior Fixation: Pedicle screw-rod system implantation, vertebral fusion.
- Minimally Invasive Surgery (MIS): Includes micro-invasive dilators and nerve retractors for reduced tissue trauma.
III. Design Features- Standardized Specifications: Based on 5.5mm diameter, compatible with corresponding screw-rod systems.
- Modular Configuration: Adjustable components for lumbar/cervical procedures (e.g., specialized packs).
- High-Safety Materials:
- Stainless steel (06Cr19Ni10, 17-4ph) for corrosion resistance;
- Aluminum alloy (e.g., 2A12) for lightweight trial rods.
