Arthroscopic Accessory Surgical Instrument-Nucleus Pulposus Forceps

Introduction to Arthroscopic Accessory Surgical Instrument-Nucleus Pulposus Forceps (2.0MM×180MM, 45-Degree Upward Bent and Straight Types)
In arthroscopic spinal surgery, the nucleus pulposus forceps with specifications of 2.0MM×180MM, available in both 45-degree upward bent and straight configurations, play a significant role.
I. Instrument Design and Specifications
The 2.0MM diameter is deliberately designed to access narrow intervertebral spaces with minimal invasiveness. It allows surgeons to reach the target area, i.e., the nucleus pulposus region, without causing excessive damage to the surrounding vertebral structures and soft tissues. The 180MM length provides an adequate reach, enabling precise manipulation deep within the spinal column.
The 45-degree upward-bent version offers unique advantages. It is especially useful when dealing with hard-to-reach areas or when the nucleus pulposus has migrated slightly upward. The angled design allows the surgeon to approach the tissue from a more favorable angle, enhancing the ability to grasp and remove the degenerated or herniated nucleus pulposus fragments. In contrast, the straight type is more straightforward in its application, providing direct access and a more familiar handling experience for surgeons in certain routine cases.
II. Surgical Applications
Herniated Disc Treatment
In cases of lumbar disc herniation, the nucleus pulposus forceps are essential. The surgeon inserts the forceps through the arthroscopic portal, carefully guided by the endoscopic view. For the best version, when the herniated fragment is tucked away in a recessed part of the disc space, the 45-degree angle allows it to be hooked and retrieved effectively. The straight type is often used when the fragment is more centrally located and easily accessible. By precisely removing the herniated nucleus pulposus, the pressure on the adjacent nerve roots is relieved, alleviating symptoms such as back pain and leg numbness.
Spinal Degeneration Management
In the context of spinal degeneration where the nucleus pulposus undergoes changes and may cause instability or pain, these forceps can be used to clean up the damaged or fragmented nucleus pulposus. The 2.0MM×180MM size permits delicate work, ensuring that only the affected tissue is removed while preserving the healthy surrounding structures. This helps to maintain the integrity of the intervertebral disc and delay further degeneration.
III. Advantages and Significance
Overall, the arthroscopic nucleus pulposus forceps, with their specific sizes and designs, offer multiple benefits. Their ability to access the delicate spinal environment, combined with the option of angled or straight configurations, provides surgeons with the tools they need to perform precise and minimally invasive procedures. By effectively removing problematic nucleus pulposus tissue, they contribute to improved patient outcomes, reduced postoperative complications, and faster recovery times, making them an indispensable part of arthroscopic spinal surgeries.
