Frequently asked questions
If you have a herniated disc or a bulging disc, we recommend a personalized ergonomic assessment. Optimizing seating posture, arm support, pedal positioning, and overall operating posture can help reduce spinal loading and improve comfort during surgery. Because back pain is often influenced by several factors, a comprehensive evaluation of the surgeon’s working posture should be performed to identify opportunities for ergonomic improvement. For best results, these adjustments are often combined with individualized guidance and movement assessment from a physiotherapist or ergonomics specialist.
Proper support for the pelvis, back, shoulders, and arms is essential for maintaining comfort and precision during surgery, combined with well-placed pedals and equipment, contribute to better ergonomics and precision.
Several published studies and systematic reviews have shown that musculoskeletal disorders are common among surgeons, particularly those performing microsurgical and microscope-assisted procedures. Depending on the specialty and study population, more than 80% of surgeons report experiencing work-related pain or discomfort affecting the neck, shoulders, back, or upper extremities at some point during their careers. These findings highlight the importance of proper ergonomics, optimized working posture, and ergonomic support systems in helping to reduce physical strain, maintain surgical performance, and promote long-term occupational health.
Good ergonomics improves stability and reduces muscle fatigue. This helps minimize unwanted micromovements and supports greater precision and control.
The Carl Mk2 weighs approximately 43 kg (95 lbs).
Carl chairs are designed to reduce physical strain through adjustable armrests, ergonomic seating, and customizable positioning that help reduce static loading and repetitive stress.
Carl Mk3 and Carl Mk3E are the most popular models in neurosurgery. They offer individually adjustable armrests, optional pedal platforms, and ergonomic support for long and physically demanding procedures.
The electric models are designed for a Safe Working Load (SWL) of up to 150 kg (331 lbs), while the mechanical models support up to 120 kg (264 lbs).
Carl surgical chairs differ from traditional surgical chairs through their unique combination of ergonomics, stability, and advanced arm support systems. The extensive adjustment options allow each chair to be customized to the surgeon’s height, preferred working posture, and surgical specialty. This helps improve surgeon ergonomics, reduce musculoskeletal strain, and maintain a high level of precision and comfort during both short and long surgical procedures.
Carl Mk2 R7 is the most widely used and recommended model for ophthalmic surgery. Its unique base design provides excellent ergonomics, access to the surgical field, and ample space for microscope pedals and related equipment.
