What is the name of the delicate ronguers used to remove intervertebral disc tissue?

The delicate ronguers specifically designed for removing intervertebral disc tissue are known as Pituitary ronguers. These instruments are characterized by their design, which allows for precise and controlled removal of tissue in tight and confined spaces, such as the intervertebral discs. They typically have a curved shape and a pair of cutting edges that enable surgeons to grasp and excise disc material with minimal trauma to the surrounding structures. This precision is crucial when working near sensitive spinal components, as excessive force or imprecise tools could lead to complications such as nerve damage or bleeding.

In contrast, the other instruments mentioned (Freer, Potts, and Denis) serve different purposes in surgery. For example, Freer elevators are generally used for dissection and utility in soft tissue manipulation, Potts scissors are utilized in vascular surgery for cutting and dissecting tissues, and Denis distractors are orthopedic tools for stabilizing or distracting bone fragments. None of these instruments are specifically intended for the delicate task of disc tissue removal, which is where Pituitary ronguers excel.
