Application scenarios in spinal surgery
Application in cervical spine surgery
Treatment of intervertebral disc herniation: In UBE surgery for cervical disc herniation, curettes with large angle bends and sagittal bends can play an important role. After entering the cervical spine area through the UBE surgical channel, the curette can use its bending characteristics to approach the protruding nucleus pulposus from different angles. Sagittal bends help the curette enter the front of the intervertebral disc space and clean the degenerated annulus fibrosus and nucleus pulposus tissue. Large angle bends can handle the nucleus pulposus protruding to the intervertebral foramen or the side of the spinal canal, reduce the compression of the nerve roots and spinal cord, and relieve the pain, numbness and other symptoms of the patient's upper limbs.
Assistance in cervical fusion surgery: In the preparation stage of cervical fusion surgery, curettes can be used to clean the cartilage tissue and a small amount of bone on the surface of the vertebral endplate. Curettes with large angle bends and sagittal bends can better fit the shape of the vertebral endplate, especially when dealing with the endplates at the front and side edges of the vertebral body, which can more comprehensively clean the surface tissue, increase the contact area between the fusion device and the endplate, and improve the success rate of fusion surgery.
Application in lumbar spine surgery
Surgery for lumbar disc herniation: In UBE surgery for lumbar disc herniation, the curette is an important tool for cleaning disc tissue. A curette with a large angle of curvature can penetrate into the intervertebral foramen to remove the protruding nucleus pulposus and annulus fibrosus fragments that compress the nerve roots. A curette with a sagittal curve can clean the diseased tissue in the front of the disc space along the lumbar lordosis. For example, in common lumbar disc herniation sites such as L4-L5 or L5-S1, the curette can effectively reduce the compression of the nerve roots and improve the patient's lower limb pain, numbness and other nerve compression symptoms.
Lumbar spinal canal decompression surgery: In the surgical treatment of lumbar spinal stenosis, the curette is used to scrape the hyperplastic bone and hypertrophic yellow ligament in the spinal canal. A curette with a large angle of curvature can reach narrow sites such as the lateral wall of the spinal canal and the lateral recess, and clean the bone hyperplasia that compresses the nerve roots. The curette with sagittal curvature can scrape the bone hyperplasia and protruding disc tissue in the front of the spinal canal along the sagittal plane of the spinal canal, expand the volume of the spinal canal, decompress the nerves, and relieve the patient's intermittent claudication and other symptoms.
Application in thoracic spine surgery
Treatment of thoracic disc lesions: In the surgery of thoracic disc herniation or degeneration, the large angle curvature and sagittal curvature of the curette can help doctors operate in the relatively narrow space of the thoracic spine. The curette can bypass the ribs and nerves around the thoracic spine, penetrate into the thoracic disc space, and clean the diseased nucleus pulposus and annulus fibrosus tissue. This precise operation helps to reduce the compression of the thoracic spinal cord and nerve roots, and improve the patient's chest and back pain and neurological symptoms.
Surgical assistance for thoracic fractures: In the surgical treatment of thoracic fractures, the curette can be used to clean the hematoma and broken bone tissue around the fracture end. The curette with large angle curvature and sagittal curvature can clean the tissue around the fractured vertebra without damaging the spinal cord and peripheral nerves, creating good conditions for fracture reduction and fixation, and promoting fracture healing.
Operation precautions and skills
Operation precautions
Since UBE surgery relies on endoscopic visualization, it is necessary to ensure that the endoscopic field of view is clear before using the curette, and accurately judge the relationship between the curette and the surrounding tissues. During the insertion and operation of the curette, special attention should be paid to avoid damaging important tissues such as nerves and blood vessels. The cervical, thoracic and lumbar regions are densely distributed with nerves and blood vessels. During operation, the curette's movement trajectory should be carefully controlled according to the curette's bending direction and angle. At the same time, attention should be paid to the cleaning and disinfection of the curette to avoid surgical infection caused by instrument contamination.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the spinal structure characteristics of the surgical site, combined with the curette's bending shape, slowly insert the curette at an appropriate angle and direction. During the insertion process, use its 3MM diameter to carefully enter the surgical area along the natural anatomical gap or the established working channel to avoid forced insertion and damage to surrounding tissues. For example, in cervical spine surgery, when inserting a curette with a large angle of curette, the curved part of the curette can be inserted along the lateral or anterior gap of the cervical spine first, and then the direction can be adjusted to enter the intervertebral disc space or the vertebral edge.
Scraping techniques: When scraping the diseased tissue, gently touch the blade of the scraper to the target tissue, and use appropriate force and scraping method according to the hardness and toughness of the tissue. For softer tissues, such as nucleus pulposus or hematoma, gentle scraping can be used; for harder bone hyperplasia tissue, you can start from the edge and gradually go deeper, using multiple, small-scale scraping operations to avoid excessive force at one time, which may cause damage to surrounding tissues or breakage of the scraper. During the entire operation, the position and operation of the scraper should be flexibly adjusted in combination with real-time endoscopic observation to achieve the best surgical effect. For example, in lumbar spinal canal decompression surgery, when using a sagittal curved curette to scrape bone hyperplasia in the front of the spinal canal, the scraping force and depth should be carefully controlled according to the bone thickness and distance from the nerve seen under the endoscope.
