Product Overview
This specialized range of upper arm tractors, ankle retractors, backplane extension plates, and single-piece kneeling boards / foot baffles addresses precise positioning and traction needs in the orthopedic, anorectal, and general surgery operating room. Each accessory is engineered to provide stable, adjustable support for specific anatomical regions — the elbow, the ankle, the spinal column, and the knee — enabling surgeons to achieve optimal exposure, traction alignment, and patient comfort during procedures that demand exacting limb or trunk positioning.
All structural components are fabricated from either 304 stainless steel or medical-grade aluminum alloy, delivering the corrosion resistance, structural rigidity, and autoclave compatibility demanded by high-turnover surgical environments. Patient-contact surfaces are padded with high-density rebound memory sponge encased in PU leather, providing superior pressure redistribution during prolonged procedures while remaining easy to wipe clean and compatible with hospital-grade disinfectants. Every variant in the range is designed for universal compatibility with any brand of operating table, fitting standard side rails and mounting interfaces without proprietary adapters.
From the coarse-and-fine adjustment upper arm tractor that delivers precise elbow traction for distal radius fixation and elbow arthroscopy, to the ankle retractor that secures the foot for percutaneous Achilles repair, to the customizable backplane extension plate that lengthens the table surface for full-spine imaging, to the adjustable kneeling board that positions the patient's knee for posterior knee and anorectal procedures — this product family provides a single-source solution for the full spectrum of limb and trunk positioning requirements.
Key Features & Clinical Advantages
304 stainless steel and aluminum alloy construction — Structural frames and fixators are fabricated from medical-grade 304 stainless steel or lightweight aluminum alloy, providing excellent corrosion resistance, long-term durability, and full autoclave compatibility across repeated sterilization cycles.
High-density rebound memory sponge with PU leather — All patient-contact surfaces are padded with high-density memory sponge that conforms to the patient's anatomy, distributing pressure evenly and reducing the risk of nerve compression and soft-tissue injury during prolonged procedures. The PU leather cover provides a smooth, non-porous surface that is easy to wipe clean, resists fluid absorption, and withstands repeated disinfection without cracking or degradation.
Universal operating table compatibility — Every accessory in the range mounts to standard side-rail operating tables from any manufacturer, eliminating the need for brand-specific adapters and simplifying procurement for multi-brand hospital environments.
Coarse and fine adjustment modes (upper arm tractor) — The upper arm tractor features dual adjustment modes — coarse adjustment for rapid positioning and fine adjustment for precise traction force calibration — enabling the surgeon to dial in the exact traction vector and magnitude required for each procedure.
Adjustable inserting rod spacing (kneeling board) — The single-piece kneeling board features inserting rods on both sides with adjustable spacing of 600–650 mm, allowing the board width to be customized to the patient's body dimensions and the specific procedural requirements.
Customizable backplane extension plate dimensions — The backplane extension plate is available with customizable length and width, allowing facilities to order the exact dimensions needed to extend the table surface for their specific spinal surgery requirements — from cervical to thoracic to full-spine coverage.
Model Variants & Specifications
Upper Arm & Elbow Traction
FP-028-D2 — Upper Arm Tractor / Elbow Tractor
A precision traction device constructed from 304 stainless steel, designed to be fixed on both sides of the operating table side rail and at the patient's palm to apply controlled traction to the elbow joint. The tractor features coarse and fine adjustment modes — the coarse adjustment allows rapid positioning of the traction arm to the approximate working height and angle, while the fine adjustment enables precise calibration of the traction force and vector for optimal surgical exposure. This dual-mode system is essential for procedures requiring exact traction control — including distal radius fracture reduction, elbow arthroscopy, open reduction and internal fixation of humeral fractures, and elbow contracture release — where even small deviations in traction force or angle can affect the quality of reduction or the surgeon's view of the joint. The bilateral fixation on both sides of the side rail provides symmetrical load distribution, preventing the tractor from tilting or shifting under sustained traction loads. The palm fixation point ensures that traction force is transmitted through the entire upper limb axis, creating a stable, controlled traction environment for the elbow.
Ankle Traction
FP-028-D3 — Ankle Retractor
A traction device constructed from 304 stainless steel, designed to be fixed on the operating table side rail with adjustable straps that secure the patient's ankle for controlled ankle traction. The retractor provides a stable, adjustable anchor point for applying traction force to the ankle joint — essential for percutaneous Achilles tendon repair, ankle arthroscopy, distal tibia and fibula fracture reduction, and ankle fusion procedures. The strap-based fixation accommodates patients of different ankle sizes and allows the surgical team to adjust the strap tension to achieve the desired traction force without creating focal pressure points that could compromise skin integrity or neurovascular function. The stainless steel construction withstands repeated sterilization, and the side-rail mounting ensures compatibility with any operating table brand.
Backplane Extension Plates
FP-029-A1 / FP-029-A2 / FP-029-A3 — Backplane Extension Plate
A family of backplane extension plates available in 304 stainless steel (FP-029-A1/A2) or aluminum alloy (FP-029-A3), with customizable length and width to match the specific requirements of each facility's spinal surgery program. The extension plate lengthens the back segment of the operating table, providing additional support surface for the patient's torso during spinal procedures that extend beyond the standard table length — including full-spine fusion, multi-level laminectomy, and spinal deformity correction. The patient-contact cushion is constructed from high-density rebound memory sponge encased in PU leather, providing superior pressure redistribution across the thorax and abdomen during prolonged prone positioning — reducing the risk of pressure-related skin injury and improving patient comfort during lengthy spinal procedures. The memory sponge's high-rebound characteristics ensure that the cushion maintains its shape and support properties throughout the procedure without bottoming out under the patient's weight. The stainless steel variants offer maximum rigidity for heavy-load applications, while the aluminum alloy variant provides reduced weight for easier handling and repositioning between cases.
Kneeling Board / Foot Baffle
FP-030-A1 — Single-Piece Kneeling Board / Foot Baffle / Foot Board
A versatile positioning accessory constructed from 304 stainless steel with a square fixator that mounts directly to the operating table side rail. The board features inserting rods on both sides with adjustable spacing of 600–650 mm, allowing the board width to be customized to the patient's body dimensions and the specific procedural requirements. The patient-contact surface is padded with high-density rebound memory sponge covered in PU leather, providing comfortable, pressure-distributing support for the patient's knee, shin, or foot during procedures requiring kneeling, prone, or flexed-knee positioning.
This single-piece design serves multiple clinical functions — as a kneeling board for posterior knee surgery, meniscal repair, and ACL reconstruction where the patient's knee is flexed over the board edge; as a foot baffle for anorectal surgery, pilonidal cyst excision, and perineal procedures where the foot board provides a stable platform for the jackknife or prone position; and as a foot board for general lower-limb positioning where a rigid, padded foot support is needed. The 600–650 mm adjustable rod spacing ensures the board can accommodate patients of different body widths, from slender adults to larger patients, while maintaining a secure, stable platform. The square fixator provides positive anti-rotational engagement with the side rail, preventing the board from shifting under the dynamic loads of surgical manipulation.
