Description

Novel cover plate type rotatable vertebral lamina rongeur structure

Technical Field

The utility model relates to an orthopedics neurosurgery field especially relates to the spinal column operation field, specifically indicates a novel but rotary vertebral plate rongeur structure of apron formula.

Background

The cover plate type rotating vertebral plate rongeur is used in spinal surgery, and the exposure of spinal nerves by removing vertebral plates is a key step for successful surgery. Also can be used for extraneural cranial base region tumor operation.

Degenerative spinal diseases are the most common types of all spinal disorders, and the common types are herniated discs, spinal stenosis, and spondylolisthesis, which share the common feature of causing compression of the dura mater or nerve roots, thus requiring laminectomy and decompression procedures. It is well known that there are numerous blood vessels, spinal cords and nerves around the spine, so that spinal surgery cannot be performed with a broad axe as in conventional orthopedic surgery, and a light and advantageous tool is often required for the separate resection of the spine from the surrounding tissue. Rongeur, vertebral plate rongeur, drum pounding and abrasive drilling are common instruments used in the operation. In addition, because of the presence of the dura mater and spinal cord below the vertebral plate, the vertebral plate rongeur is the most important tool in the final opening of the spinal canal.

The cranio-basilar region tumor operation is suitable for intracranial tumors invading cranio-basilar and maxillofacial neck, such as meningioma, neurofibroma, chondroma and teratoma. Tumors which are primarily developed at the basis of cranium, such as osteoma, giant cell tumor, etc. Extracranial tumors invade the skull base. Such as malignant tumor of maxillary sinus invading temporomandibular fossa and basis cranii; malignant tumor of parotid gland invades skull base; jaw sarcoma, chondrosarcoma, and maxillofacial soft tissue sarcoma affect basis cranii, and external ear, middle ear, and temporal facial skin squamous cell carcinoma invade basis cranii. The vertebral plate rongeur is used for expanding the operation access and exposing the skull base tumor in the operation.

The existing vertebral plate rongeur used clinically has the following defects: the utility model discloses a surgical forceps, including the pole of pincers, the pole of pincers can not rotate the angle, and the opening direction that causes keeping in the palm is fixed, and the art person like this wants to change the direction of keeping in the palm, can only make the position of whole vertebral plate rongeur take place to rotate through rotatory arm to reach the purpose that changes the direction of keeping in the palm, like this medical personnel need often change the arm position, operate inconveniently, the degree of difficulty is big when carrying out the cutting operation at special angle position, influences patient's treatment effect of performing the operation.
