Featured Spinal Pedicle Screw & Instrument Series
Zhejiang INAR Medical Co., Ltd. supplies complete spinal fixation portfolios, including polyaxial, monoaxial, reduction pedicle screws, and dedicated surgical instrument sets for open and MIS thoracolumbar procedures.
Titanium Polyaxial Pedicle Screw MIS System
Designed for minimally invasive and open thoracolumbar posterior fixation. Features self-tapping threads and low-profile friction heads to reduce tissue disruption.
Thoracolumbar Monoaxial Reduction Pedicle Screws
Engineered for spinal deformity correction and spondylolisthesis reduction. Extended break-away tabs offer precise rod reduction without auxiliary tools.
Fenestrated Bone Cement Pedicle Screw System
Cannulated screw design with distal side holes for PMMA bone cement injection. Provides augmented anchorage in osteoporotic bone conditions.
Percutaneous MIS Spine Surgical Instrument Set
Comprehensive stainless steel surgical tray including bone awls, taps, dilators, rod inserters, and torque-limiting screwdrivers designed for seamless pedicle screw placement.
Titanium Mesh Cages & Interbody PEEK Cages
Biocompatible lumbar and cervical interbody fusion cages offering optimal modulus of elasticity, teeth serrations to prevent migration, and radiolucent marker pins.
Lumbar Polyaxial Pedicle Screw 3.5 / 5.5 System
Dual-lead thread design speeds up insertion time while providing high pull-out resistance. Compatible with titanium cross-links and curved connect rods.
