Product Title
Shoulder Knife Holder Beach Chair and Shoulder Arthroscopic Traction Frame System | 304 Stainless Steel and Aluminum Alloy Construction | 360-Degree Head Adjustment | PU Leather Cushion with High-Density Memory Sponge | Universal Operating Table Side-Rail Compatibility
Product Overview
This comprehensive shoulder surgery positioning system encompasses the full range of devices required for beach-chair shoulder surgery and arthroscopic traction procedures — from the beach-chair shoulder knife holder that positions the patient in the semi-recumbent seated posture, to the shoulder traction frames that provide controlled, multi-directional traction for arthroscopic joint access. Each component in the system is engineered from either 304 stainless steel or medical-grade aluminum alloy, delivering the structural rigidity, corrosion resistance, and autoclave compatibility demanded by the high-load, high-moisture environment of shoulder surgery.
All patient-contact surfaces are padded with high-density memory sponge and encased in PU leather covers that can be wiped clean and disinfected rapidly between cases — a critical feature in the high-turnover environment of ambulatory surgery centers and hospital operating rooms where shoulder arthroscopy volumes are among the highest of any outpatient procedure. The beach-chair models feature 360-degree head adjustment and easy-disassembly design for thorough cleaning, while the traction frame models offer multi-position fixation — lateral, posterior, and foot — to support the full spectrum of shoulder arthroscopy approaches.
Whether the surgical team performs open shoulder stabilization in the beach-chair position, arthroscopic rotator cuff repair with traction-assisted joint distraction, or combined open-arthroscopic procedures requiring rapid intraoperative position changes, this system provides the precise, stable, and reproducible positioning platform that shoulder surgery demands.
Key Features & Clinical Advantages
304 stainless steel and aluminum alloy construction — Structural frames are fabricated from medical-grade 304 stainless steel for maximum strength and corrosion resistance, or lightweight aluminum alloy for reduced weight and easier handling — both materials withstand repeated autoclave sterilization and chemical disinfection without degradation.
360-degree head adjustment (beach chair) — The beach-chair shoulder knife holder features full 360-degree rotational adjustment of the head support, allowing the surgical team to position the patient's head at the exact angle required for optimal surgical exposure of the glenohumeral joint, subacromial space, or acromioclavicular joint — regardless of whether the procedure is performed on the left or right shoulder.
Side-rail plug-in design with adjustable spacing — The beach-chair mounts directly to the operating table side rail via a plug-in interface with adjustable spacing, enabling the unit to be centered on the table regardless of the table's width or the patient's body dimensions. This design also allows the beach chair to be positioned for both left and right shoulder operations without reconfiguration of the mounting hardware.
High-density memory sponge with PU leather cover — All patient-contact cushions are constructed from high-density rebound memory sponge that conforms to the patient's back, head, and torso contours, distributing pressure evenly during the semi-recumbent beach-chair position. The PU leather cover provides a smooth, non-porous surface that can be wiped clean and disinfected in seconds between cases — supporting strict infection-control protocols in high-volume ambulatory surgery centers.
Easy disassembly for cleaning — The beach-chair design allows rapid disassembly of all cushion and frame components without tools, enabling thorough cleaning of every surface — including crevices and joints that are difficult to reach on monolithic designs. This feature is essential for maintaining compliance with infection-control standards in facilities performing high volumes of shoulder surgery.
Gas-spring assisted positioning (FP-028-B) — The imported gas-spring design provides smooth, effort-free adjustment of the beach-chair's backrest angle, allowing the surgical team to fine-tune the patient's seated position with minimal physical effort — even when the patient is already positioned on the chair. The gas-spring mechanism also enables the entire beach-chair unit to be placed on a transfer trolley after surgery, facilitating safe, comfortable patient transfer from the operating table to the recovery stretcher without requiring the patient to stand or bear weight on the operative shoulder.
Multi-position traction capability (FP-028-D) — The stainless steel shoulder traction frame meets the positioning requirements of lateral, posterior, foot, and other body areas, providing versatile traction vector options for the full range of arthroscopic approaches — from standard posterior portal access to lateral decubitus positioning and combined approaches.
Three-point traction design (FP-028-C) — The aluminum alloy traction frame employs a three-point fixation design for lateral-position traction, distributing traction forces across three contact points to create a stable, balanced traction environment that minimizes focal pressure on any single anatomical structure.
Model Variants & Specifications
Beach-Chair Shoulder Knife Holders
FP-028-A — Shoulder Knife Holder / Beach Chair (Standard)
The standard beach-chair shoulder knife holder, constructed from 304 stainless steel with a side-rail plug-in design featuring adjustable spacing to accommodate different table widths and patient body sizes. The unit supports both left and right shoulder operations without reconfiguration — the adjustable spacing allows the chair to be centered on the table, and the 360-degree head adjustment ensures the patient's head can be rotated to the optimal position for the surgical approach regardless of which shoulder is being operated on. The patient-contact surfaces are padded with high-density memory sponge covered in PU leather, providing comfortable support for the patient's back, head, and torso during the semi-recumbent beach-chair position. The PU leather cover can be wiped clean and disinfected rapidly between cases, and the entire unit disassembles easily for thorough cleaning — including the cushion, head support, and frame components. This model is the workhorse of the beach-chair range, providing reliable, proven positioning for the full spectrum of open and arthroscopic shoulder procedures performed in the semi-recumbent position — including rotator cuff repair, shoulder stabilization, acromioplasty, distal clavicle excision, and total shoulder arthroplasty.
FP-028-B — Shoulder Knife Holder / Beach Chair (Gas-Spring Assisted with Transfer Trolley)
An advanced beach-chair variant that upgrades the standard manual backrest adjustment to an imported gas-spring mechanism for smooth, effort-free recline and upright positioning. The gas-spring design allows the surgical team to adjust the backrest angle with minimal physical force — a significant ergonomic advantage when repositioning the patient intraoperatively or when adjusting the chair for patients of different body sizes. The gas-spring mechanism also enables a unique patient transfer workflow: after the procedure is complete, the entire beach-chair unit — with the patient still seated — can be placed on a transfer trolley and wheeled directly to the recovery area. This eliminates the need to transfer the patient from the beach chair to a stretcher while the operative shoulder is still vulnerable, reducing the risk of post-operative displacement, pain, and complications. The gas-spring model retains all the features of the standard FP-028-A — including 360-degree head adjustment, adjustable side-rail spacing, high-density memory sponge cushioning, and PU leather covers — while adding the ergonomic and patient-safety advantages of gas-spring operation and trolley-based transfer.
Shoulder Traction Frames
FP-028-C — Shoulder Traction Frame (Aluminum Alloy, Three-Point Design)
A lightweight shoulder traction frame constructed from aluminum alloy, featuring a three-point design optimized for lateral-position traction during shoulder arthroscopy. The three-point fixation distributes traction forces across three contact points on the patient's torso and upper limb, creating a balanced, stable traction environment that provides consistent joint distraction without creating focal pressure points that could compromise skin integrity or neurovascular function. The frame's received material (the traction interface components that contact the patient) is adjustable to accommodate different patient body sizes and procedural requirements, and all patient-contact components can be disinfected and cleaned rapidly between cases. The aluminum alloy construction provides significant weight reduction compared to stainless steel alternatives, making this model the preferred choice for facilities where the traction frame must be frequently repositioned, transported between rooms, or adjusted intraoperatively. The three-point lateral traction design is particularly well-suited for arthroscopic rotator cuff repair, labral repair, and subacromial decompression performed in the lateral decubitus position.
FP-028-D — Shoulder Traction Frame (Stainless Steel, High Strength, Multi-Position)
A heavy-duty shoulder traction frame constructed from 304 stainless steel for maximum strength and rigidity, featuring a universal clamp that fixes directly to the operating table side rail. Unlike the lateral-only FP-028-C, this model meets the positioning requirements of lateral, posterior, foot, and other body areas — providing the versatility needed for facilities that perform shoulder arthroscopy in multiple patient positions or that require the traction frame to serve double duty for other orthopedic traction applications. The universal clamp ensures compatibility with any operating table brand, while the stainless steel construction provides the structural rigidity needed to maintain consistent traction force under heavy loads — essential for procedures requiring significant joint distraction, such as total shoulder arthroplasty or revision shoulder surgery where scar tissue and capsular contracture create high resistance to traction. All patient-contact surfaces are covered in PU leather for rapid disinfection between cases. This model is the most versatile traction frame in the range, suitable for facilities that need a single traction system to support the full spectrum of shoulder arthroscopy positions and approaches.
Forearm & Elbow Tractor
FP-028-D1 — Forearm Tractor / Elbow Tractor
A precision traction device constructed from 304 stainless steel, designed to be fixed on the operating table side rail with the patient's palm secured in the palm tractor for controlled traction of the elbow joint and stable palm support. This accessory serves as a companion device to the shoulder traction system, providing controlled upper-limb traction for procedures that extend beyond the glenohumeral joint to include the elbow, forearm, and wrist. The side-rail mounting ensures compatibility with any operating table brand, while the palm tractor provides a secure, comfortable fixation point that transmits traction force through the entire upper-limb axis — creating a stable, controlled traction environment for elbow arthroscopy, distal radius fracture reduction, wrist arthroscopy, and other procedures requiring precise upper-extremity traction. The stainless steel construction withstands repeated sterilization, and the palm fixation interface is designed to distribute traction pressure across the palm and fingers without creating focal compression of the median or ulnar nerves.
Clinical Applications
