Abstract

Single-unit cutting head systems for safe removal of nucleus pulposis tissue are provided. The cutting heads compose a part of the systems that are provided to address several problems, including clogging of state-of-the-art systems during removal of such tissue, for example. The target tissue can include any tissue that is accessible through a small surgical opening, for example, a joint tissue such as a meniscus or an intervertebral tissue, such as a nucleus pulposus. The devices can be referred to as orthopedic tissue removal devices having cutting heads associated with vacuum systems, making the systems useful in several procedures, including X-LIF (lateral approach to an intervertebral fusions) procedures, T-LIF (transforaminal approach to intervertebral fusions) procedures, P-LIF (posterior approach to intervertebral fusions), and a percutaneous, transforaminal approach (Kambin triangle access).
