Description

Technical Field

[0001] The utility model relates to the technical field of occluders, in particular to a thoracic intervertebral foramen occluder. Background Art

[0002] Communicating tumors inside and outside the thoracic spinal canal, also known as dumbbell-shaped tumors, are mostly neurothecomas that grow along the spinal nerves. The part inside the spinal canal can be located under the dura mater or only outside the dura mater. It grows toward the thoracic vertebrae through the intervertebral foramen in a dumbbell shape, often accompanied by enlargement of the intervertebral foramen. The tumor can also originate from the posterior mediastinum outside the spinal canal and grow into the spinal canal through the intervertebral foramen in a dumbbell shape. The part of the tumor located in the thoracic cavity can grow huge, reaching more than 5-6 cm. Surgical resection is the only effective way to treat this disease.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: during tumor resection surgery, thoracic surgery separates and removes the tumor base with the assistance of a video-assisted thoracoscope, and the two departments meet at the intervertebral foramen to ensure complete tumor resection. At the same time, in order to reduce the probability of infection, autologous muscle, protein glue and other materials are generally used to block the intervertebral foramen. However, these materials may be absorbed, easily displaced, and cannot be completely blocked. Therefore, a thoracic intervertebral foramen occluder is proposed to address the above-mentioned problems. Utility Model Content
