UBE surgical tools-UBE curette straight forward curved medium

Structural features and advantages
Size adaptability: The 4MM diameter allows the curette to have good passability in UBE surgery. In spinal surgery, the surgical channel is relatively narrow. This size can ensure that the curette can enter the surgical site without causing excessive pressure on the surrounding tissues. For example, in narrow areas such as the intervertebral foramen of the cervical or lumbar spine, a 4MM curette can reach the lesion site relatively smoothly and treat the local tissue.
Advantages of the forward bend design: The forward bend design allows the curette to better adapt to the physiological curvature and complex anatomical structure of the spine. When dealing with some pathological tissues located in front of or in front of the spine, such as bone hyperplasia at the front edge of the vertebral body, the front of the intervertebral disc herniation, etc., the forward bend curette can more conveniently contact the target tissue without excessively adjusting the angle of the surgical instrument, reducing the risk of traction and injury to the surrounding tissues. It can operate along the natural curve of the spine, improving the flexibility and accuracy of the surgical operation.
Application scenarios in spinal surgery
Application in intervertebral disc surgery
In UBE surgery for intervertebral disc herniation, the curette can be used to clean the degenerative tissue, broken nucleus pulposus fragments, and hyperplastic annulus fibrosus tissue in the intervertebral disc space. After locating the lesion site through endoscopy, the forward-bent 4MM curette can penetrate into the intervertebral disc space and use the curved part of its front end to effectively scrape off these lesions, creating a relatively clean surgical environment for subsequent nucleus pulposus removal or other surgical operations. For example, when dealing with L4-L5 L3-L4 L5-S1 intervertebral disc herniation, the curette can scrape off the degenerative annulus fibrosus and inflammatory tissue around the protruding nucleus pulposus tissue, which helps to reduce the inflammatory response and nerve compression symptoms.
Application of spinal canal decompression surgery
In the surgical treatment of spinal stenosis, the curette can be used to remove hyperplastic bone, hypertrophic yellow ligament, and scar tissue in the spinal canal. For bone hyperplasia on the anterior or lateral wall of the spinal canal, the forward curved curette can accurately reach the hyperplastic site, gradually scrape off the hyperplastic bone, and expand the volume of the spinal canal. When dealing with hypertrophy of the yellow ligament, the curette can scrape off part of the hypertrophic ligament tissue to relieve its compression on the spinal cord and nerve roots. For example, in surgery for cervical spinal stenosis, the curette can carefully clean the diseased tissue in the spinal canal while avoiding damage to the spinal cord and nerve roots, thereby improving the safety and decompression effect of the surgery.
Spinal fusion surgery assistance
In spinal fusion surgery, the curette can be used to process the cartilage tissue and cortical bone surface at the fusion site to increase the roughness of the bone graft bed and promote bone fusion. In the intervertebral space or facet joint surface to be fused, the curette can scrape off the cartilage layer to expose the bone surface, which is conducive to the close contact between the bone graft material and the bone surface and the growth of bone cells. For example, in posterior lumbar fusion surgery, the end plate of the intervertebral space is processed with a curette to provide a good foundation for the implantation of the fusion device and bone grafting, thereby improving the success rate of the fusion surgery.
Operation precautions and skills
Operation precautions
Since UBE surgery is performed under endoscopic visualization, it is important to ensure that the endoscopic field of view is clear before the operation so as to accurately determine 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 nerves and blood vessels around the spine are densely distributed, especially in areas such as the spinal canal and intervertebral foramen, and must be operated with caution. At the same time, according to the hardness and texture of the lesion tissue, the scraping force of the curette should be reasonably controlled to avoid excessive force causing damage to surrounding tissues or damage to the curette.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the structural characteristics of the surgical site, combined with the forward bending angle of the curette, insert the curette at an appropriate angle and direction. Using its 4MM diameter, slowly insert it along the natural anatomical gap or the established working channel to avoid forced insertion and damage to surrounding tissues.
Scraping skills: When scraping the lesion tissue, gently touch the front end of the curette to the target tissue, and then adjust the scraping force and direction appropriately according to the hardness and toughness of the tissue. For softer tissues, a smaller force and faster scraping frequency can be used; for harder bone hyperplasia tissue, the force can be increased appropriately, but care should be taken to scrape multiple times to avoid scraping too much tissue at one time, which may cause bleeding or damage to surrounding structures. During the entire operation, the position and operation of the scraper should be flexibly adjusted in combination with real-time observation of the endoscope to achieve the best surgical effect.
