Product Overview
The OKLand® Pneumatic Lift-Assist Stirrups for Lithotomy Surgery (OTJ001 / OTJ003) are professional Class I surgical positioning devices engineered to deliver stable, repeatable and ergonomic patient leg positioning during all major lithotomy-based procedures. As core operating-table accessories used in gynecology, urology, colorectal surgery, laparoscopic surgery and robotic-assisted surgery, these adjustable stirrups fully address the positioning requirements of patients throughout the entire surgical workflow — from initial setup to intra-operative repositioning under sterile conditions.
Manufactured by Red Sun Medizone, the OTJ001 / OTJ003 lithotomy stirrups combine a high-rigidity 304 stainless steel and aluminum-alloy supporting frame with a pneumatically assisted lift mechanism. Their boot-style cradle with integrated protecting wings delivers zero-pressure protection of the peroneal nerve and the calf, while the universal rail-clamp interface (sold separately as OGJ-005) makes them compatible with virtually all standard O.R. table side-rails used in hospitals worldwide.
Key Features & Technical Highlights
Designed for clinical versatility, structural stability and one-person intra-operative adjustability, the pneumatic lithotomy stirrups integrate multiple humanized and high-performance features that meet the demands of modern minimally invasive and robotic surgery:
Pneumatic Lift-Assist Adjustment: An internal pneumatic gas spring assists vertical adjustment of the supporting arm, allowing a single operator to raise or lower each leg to the precise lithotomy height with minimal effort. This dramatically reduces the workload of circulating nurses during long surgeries.
Multi-Directional (All-Direction) Articulation: Lithotomy angle, abduction, adduction, Trendelenburg-related height and flexion can all be independently adjusted through dedicated lock knobs and integrated flexion / lithotomy angle indicators — giving surgeons complete control of intra-operative leg positioning even under sterile drapes.
Zero-Pressure Protecting-Wing Design: The patented protecting wings cradle the calf and lateral knee, eliminating pressure on the popliteal fossa and gastrocnemius muscle and removing the risk of peroneal-nerve injury — the most common positioning-related complication of lithotomy surgery.
Self-Adjusting Boot Cradle: As the stirrup is repositioned, the boot automatically rotates to redistribute pressure across the heel, ankle and calf. The foot, ankle and calf are fully wrapped in the protective cover pad for stable, evenly distributed support.
Integrated Angle Indicators (Meter Readers): Built-in flexion and lithotomy meters allow the operator to record, reproduce and verify positioning angles for each case — improving surgical-team consistency and supporting clinical documentation.
Choice of Boot-Cover Materials: Available in Cotton Cover (reusable, washable) or Polymer Total Gel Cover (single-use gel pads for maximum pressure redistribution during extended procedures).
Two-Step Setup & Universal Compatibility: Setup takes only two steps — (1) attach the rail clamp to the O.R. table side-rail adjacent to the patient's hip, (2) plug the stirrup into the clamp and lock. Compatible with any standard operating-table side-rail through the OGJ-005 universal-clamp accessory.
Optional Mobile Storage Cart (OTJ01-TC): A purpose-built cart (101 × 45 × 45 cm) holds both stirrups for clean storage and rapid room-to-room transport between operating theatres.
Clinical Applications
The pneumatic lithotomy stirrups are widely used in any procedure that requires pre- or intra-operative adjustment of patient leg positioning. Typical specialties and procedures include:
Gynecologic (GYN) surgery — hysterectomy, oophorectomy, pelvic reconstructive surgery, vaginal surgery.
Urological surgery — transurethral resection of the prostate (TURP), radical prostatectomy, cystoscopy, ureteroscopy, percutaneous nephrolithotomy.
Colorectal and anorectal surgery — low anterior resection, hemorrhoidectomy, fistulotomy.
Laparoscopic surgery — gynecologic laparoscopy, urologic laparoscopy and general-surgery laparoscopy requiring lithotomy leg position.
Robotic-assisted surgery — robotic prostatectomy, robotic hysterectomy and robotic colorectal resection (rated for the steeper Trendelenburg and longer operative times required by robotic platforms).
Other surgical procedures requiring intermittent or continuous adjustment of patient leg positioning.
Adjustment Range & Technical Specifications
The OTJ001 and OTJ003 stirrups share the same dimensions, weight and patient-weight limit. They differ only in boot-cover configuration:
Maximum patient weight: 180 kg (396 lb).
Product weight (single stirrup): 12 kg.
Main supporting-rod length: 97 cm.
Main supporting-rod diameter: 20 mm (with built-in angle meter).
Vertical adjustment range of supporting arm: ≥ 110°.
Horizontal adjustment range of supporting arm: outer ≥ 25°, inner ≥ 9°.
Adjustment range of boot support along supporting arm: 310 mm.
Boot-cover options: Cotton (reusable, washable) or Polymer Total Gel (single-use gel pads for maximum pressure redistribution).
Compatible rail clamp: OGJ-005 Universal Clamp (50 × 85 × 80 cm, fits standard O.R. table side-rails).
Optional storage cart: OTJ01-TC Storage Cart (101 × 45 × 45 cm).
Cleaning, Disinfection & Care
After each use, wipe the stirrups clean with a hospital-grade equipment cleaner and disinfectant following the disinfectant manufacturer's instructions. Dry with a clean cotton cloth before storage. To protect the precision bearings and pneumatic gas spring, do not use gas sterilization, autoclaving, washing machines, dryers or prolonged soaking in disinfectants.
Quality & Warranty
A warranty period of 1 year is guaranteed provided the stirrups are not subject to misuse, negligence, accident or abuse.

Frequently Asked Questions
Q: What is the difference between OTJ001 and OTJ003 lithotomy stirrups?
A: The OTJ001 and OTJ003 are two configurations of the same pneumatic lift-assist stirrup platform. They share identical dimensions, weight and 180 kg maximum patient-weight rating. OTJ001 is supplied with the cotton boot cover, while OTJ003 is supplied with the polymer total-gel boot cover for enhanced pressure redistribution during extended procedures.
Q: What is the maximum patient weight supported by these stirrups?
A: The maximum patient-weight limit for both OTJ001 and OTJ003 is 180 kg (approximately 396 lb). For bariatric cases requiring up to 230 kg, the OTJ004 heavy-duty variant is also available.
Q: Which operating tables are these lithotomy stirrups compatible with?
A: Through the OGJ-005 Universal Clamp accessory, the stirrups attach to any standard O.R. table side-rail, including all major brands of electric, hydraulic and manual operating tables used in hospitals worldwide.
Q: How many staff members are required to position a patient in the stirrups?
A: The manufacturer recommends that two medical staff members simultaneously position each leg for patient safety. The pneumatic lift-assist mechanism, however, makes vertical adjustment possible for a single operator with minimal force.
Q: What is the recommended cleaning and sterilization method?
A: Wipe with hospital-grade disinfectant after each use. Gas sterilization, autoclaving, washing machines and prolonged soaking are not recommended, as they may damage the pneumatic gas spring and precision bearings.
Q: Are these stirrups suitable for robotic-assisted surgery?
A: Yes. The pneumatic lift-assist design and protecting-wing construction make them well-suited to the steep Trendelenburg positions and long operative times required by robotic prostatectomy, robotic hysterectomy and robotic colorectal surgery.
