Caspar Retractor for Lumber Vertebral Colunm 45mm

Clinical Application

Intended for retraction and sustained exposure of soft tissue and paraspinal musculature during posterior lumbar procedures. Provides a hands-free working corridor to the lumbar vertebral column for procedures such as laminectomy, discectomy, decompression and posterior fusion approaches. The 45 mm size offers a moderate working depth suitable for standard lumbar exposures where steady lateral retraction and clear visualization of the operative field are required.

Design & Configuration

The instrument employs a Caspar-style self-retaining design with a ratchet mechanism to maintain controlled lateral tension without continuous manual holding. Blade-style retraction surfaces distribute pressure across the wound margin to minimize focal tissue trauma. The self-retaining configuration frees assistants and stabilizes the operative field, improving access for instrumentation, visualization under the microscope or loupes, and implantation of spinal hardware.
