Surgical Drill Guide

Name: Bone Alignment and Drill Guide Units for Surgery – Frigate
Price: 249.00 USD
Availability: InStock

Surgical Drill Guide provides a mechanically constrained pathway that maintains angular fidelity during cortical and cancellous bone drilling. This eliminates deviations caused by manual alignment, particularly critical in anatomically dense regions like the vertebral pedicles or femoral condyles. The fixed-angle configuration ensures trajectory repeatability in multi-planar osteotomies, enabling screw paths that conform to pre-planned load axes and fracture fixation protocols. The device supports high accuracy even in cases where tactile feedback is compromised by soft tissue resistance or limited visualization.

Product Description

Surgical Drill Guide addresses angular variability introduced by freehand technique, which remains a leading contributor to screw misalignment and cortical breach. The system enforces an axis-locked drill path, reducing human-induced angular error to within clinically acceptable thresholds across variable bone densities and drill diameters. By minimizing the reliance on visual estimation or intraoperative imaging alone, Surgical Drill Guide allows for uniform performance across surgical teams, which is essential for high-volume orthopedic centers and trauma units.

Inspection Method

100% CMM (±0.005mm), Optical Comparator (20x), Go/No-Go Gauges, Lot Sampling (AQL 0.65)

Technical Advantages

Surgical Drill Guide incorporates integrated mechanical depth control mechanisms that ensure consistent penetration limits based on preoperative planning parameters. This is particularly critical when drilling near neurovascular structures or through thin cortices in pediatric or osteoporotic bone. The depth-limiting feature of the Surgical Drill Guide eliminates the need for manual stop collars or fluoroscopic confirmation, allowing the operator to achieve precise bicortical or monocortical engagement with reduced intraoperative risk.

Surgical Drill Guide is manufactured from sterilization-stable materials, such as high-performance PEEK composites and precipitation-hardened stainless steels, chosen for their resistance to thermal expansion and creep deformation. Dimensional integrity is maintained after repeated autoclave cycles, ensuring that guide alignment and bushing tolerances remain within ±0.02 mm. The construction of Surgical Drill Guide supports compliance with hospital sterilization protocols without compromising mechanical accuracy over its lifespan, which is essential for reusable surgical instrumentation in institutional procurement settings.

Industry Applications

Orthopedic Trauma Fixation

Used to guide screw trajectories in comminuted long bone fractures, ensuring accurate cortical engagement and stable internal fixation geometry.

Spinal Pedicle Screw Placement

Provides controlled drill path through pedicles, reducing medial wall breach and improving alignment for multi-level spinal instrumentation constructs.

Craniofacial Reconstruction

Enables precise drilling in complex skull or mandibular geometries, supporting alignment of mini-plates in maxillofacial fracture repair.

Pelvic and Acetabular Fracture Fixation

Facilitates accurate screw placement in narrow pelvic corridors, minimizing risk to neurovascular structures during acetabular stabilization procedures.

Arthroscopic and MIS Procedures

Used in constrained visualization environments to maintain consistent drill trajectories for anchor or screw insertion in joint-preserving surgeries.

Corrective Osteotomies

Assists in pre-planned angular corrections by guiding osteotomy drill cuts and screw paths for deformity realignment surgeries.

Anatomical Conformity for Patient-Specific Adaptation

Surgical Drill Guide offers adaptability for complex geometries through patient-specific design based on CT or MRI-derived segmentation. The system supports integration with digital planning software and additive manufacturing, allowing creation of guides that match irregular bone topographies such as pelvic columns or maxillofacial contours.

Surgical Drill Guide ensures that screw vectors align with biomechanical load paths, particularly in constructs involving multi-planar fixation like angular stable plating or polyaxial screw systems. By enforcing predefined angular orientations, the guide contributes to optimal screw-bone interface, improved load transfer, and enhanced resistance to pull-out under cyclic loading conditions.

Having Doubts? Our FAQ

Check all our Frequently Asked Question

How does Frigate ensure tolerance consistency in the manufacturing of Surgical Drill Guides?

Frigate uses multi-axis CNC machining and precision tooling to maintain dimensional tolerances within ±0.02 mm on guide sleeves and frames. All critical components are inspected using coordinate measuring machines (CMM) for angular and concentric accuracy. This ensures minimal cumulative error during multi-sleeve operations. High repeatability allows standardized performance across different surgical cases.

Can Frigate supply patient-specific Surgical Drill Guides for complex anatomical procedures?

Frigate supports patient-specific manufacturing using DICOM-to-CAD workflows based on CT/MRI imaging data. Anatomical conformity is achieved through 3D printing or 5-axis milling depending on material and application. Drill trajectory vectors are pre-validated in the digital plan and physically constrained in the final guide. This approach improves accuracy in irregular geometries like pelvic fractures or tumor resections.

What materials does Frigate use to ensure reusability and sterilization stability of Surgical Drill Guides?

Frigate manufactures Surgical Drill Guides using PEEK, Ultem™, or 17-4 PH stainless steel, selected for high thermal resistance and dimensional integrity. These materials undergo repeated autoclave testing to confirm tolerance retention and surface stability. Creep resistance and corrosion resistance are validated for long-term clinical use. This ensures guides can be safely reused without loss of precision.

How does Frigate address drill-bit compatibility across various implant systems?

Frigate designs Surgical Drill Guides with modular bushing systems to fit standard and cannulated drill bits from 1.5 mm to 4.5 mm. Interchangeable sleeves accommodate different shaft diameters and lengths while maintaining tight axial alignment. Universal interfaces ensure compatibility with major trauma and orthopedic implant systems. This flexibility reduces instrumentation redundancy in multi-system hospitals.

Does Frigate validate angular accuracy of Surgical Drill Guides before dispatch?

Yes, Frigate conducts angular validation using laser metrology or digital probe alignment tools. Each guide undergoes bench testing to confirm compliance with specified trajectory angles within ±2° tolerance. Validation reports can be provided with each production lot. This quality assurance process ensures guide reliability for high-precision surgical applications.
