UBE surgical tools-UBE curette reverse small

Structural features and advantages
Size adaptability: The 5MM 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 5MM 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 curved 5MM 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 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 treat the cartilage tissue and the 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 curette is used to treat the endplate of the intervertebral space 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 the UBE surgery is performed under endoscopic visualization, it is necessary to ensure that the endoscopic field of view is clear before the operation in order to accurately judge the relationship between the curette and the surrounding tissue. 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 the spinal canal and intervertebral foramen, so care must be taken during operation. At the same time, the scraping force of the curette should be reasonably controlled according to the hardness and texture of the lesion tissue 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 5MM 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 a faster scraping frequency can be used; for harder bone hyperplasia tissue, the force can be appropriately increased, but it should be noted that the scraping should be done in multiple times to avoid scraping too much tissue at one time, causing bleeding or damaging surrounding structures. During the entire operation, the position and operation of the curette should be flexibly adjusted in combination with real-time observation of the endoscope to achieve the best surgical effect.
UBE surgical tools Curette spine application 3MM blade reverse design
Structural features and advantages
Fine size and good passability: The 3MM diameter enables the curette to have excellent passability in UBE surgery, and can easily enter the relatively narrow operating channels and anatomical areas in spinal surgery. This is especially important for surgeries in the cervical and thoracic spine, because the anatomical structures in these areas are more delicate, and smaller surgical instruments can reduce damage and compression to surrounding tissues, reduce surgical risks, and improve surgical accuracy.
Advantages of reverse blade design: The reverse blade design is the unique feature of this curette. This design allows the curette to fit the complex anatomical structure of the spine more effectively during operation. For example, when dealing with lesions in the spinal canal or lesions on the edge of the vertebral body, the reverse blade can better adapt to the shape and position of the tissue. Compared with the traditional forward blade curette, it can contact and scrape tissue at different angles. For some lesions hidden in depressions or difficult to directly contact, the reverse blade curette can reach and clean more deeply, improving the flexibility and thoroughness of surgical operations and reducing surgical blind spots.
Application scenarios in spinal surgery
Treatment of intraspinal lesions
In UBE surgery for diseases such as spinal stenosis and intraspinal tumors, the 3MM reverse blade curette can be used to clean hyperplastic tissue, scar tissue, and tumor tissue fragments in the spinal canal. After locating the lesion site through the endoscope, the curette can carefully enter the spinal canal with its fine size and unique blade design, and accurately scrape the lesion tissue along the inner wall of the spinal canal or around the nerve root. For example, when treating spinal canal stenosis caused by hypertrophy of the yellow ligament, the reverse blade curette can penetrate into the gap between the yellow ligament and the posterior wall of the spinal canal, effectively scrape off the hypertrophic yellow ligament tissue, expand the volume of the spinal canal, reduce the compression of the spinal cord and nerve roots, and relieve the patient's lower limb pain, numbness, weakness and other nerve compression symptoms.
Vertebral marginal lesion cleaning
The curette can also play an important role in the bone hyperplasia at the edge of the vertebral body, the pathological tissue at the attachment of the intervertebral disc protrusion and the vertebral body, etc. When bone hyperplasia occurs at the anterior and lateral edges of the vertebral body of the cervical or lumbar spine, the curette can approach the lesion from a suitable angle, and use the reverse blade to gradually scrape off the hyperplastic bone, making the vertebral surface smoother and restoring the normal physiological structure and mechanical balance of the spine. At the same time, when treating intervertebral disc herniation, the curette can clean the degenerative tissue at the contact site between the protruding nucleus pulposus and the vertebral body, creating good conditions for subsequent nucleus pulposus removal or repair surgery, and reducing the risk of postoperative recurrence.
Surgical assistance for spinal trauma
In the surgical treatment of traumatic diseases such as spinal fractures and dislocations, the curette can be used to clean up the hematoma, broken bone tissue and soft tissue debris around the fracture end. Before resetting the fracture fragment, using the curette to carefully clean the fracture site helps to accurately judge the fracture situation and provide a clear surgical field of view and good bone surface contact conditions for fracture reduction and fixation. For example, in thoracic vertebral fracture surgery, the curette can clean up the hematoma and bone fragments around the fractured vertebra, so that the fracture end can be better repositioned and fixed, promote fracture healing, and reduce the occurrence of postoperative complications.
Operation precautions and skills
Operation precautions
Since UBE surgery is highly dependent on endoscopic visualization, it is necessary to ensure that the endoscopic field of view is clear before the operation, accurately judge the relationship between the curette and the surrounding tissue, and avoid blind operation that may cause damage to important tissues such as nerves and blood vessels. During the insertion and operation of the curette, special attention should be paid to controlling the strength and direction, because the anatomical structure around the spine is complex and fragile, and a little carelessness may cause serious consequences. At the same time, the blade of the curette should be regularly checked for sharpness. If it is worn, it should be replaced in time to ensure the efficiency and quality of the surgical operation.
Operation skills
Insertion skills: According to the anatomical path observed by the endoscope and the structural characteristics of the surgical site, slowly insert the curette at an appropriate angle and direction. Using its 3MM fine size, carefully enter the surgical area along the natural anatomical gap or the established working channel to avoid forced insertion and damage to surrounding tissues.
Scraping skills: When scraping the diseased tissue, gently touch the reverse blade of the curette 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 hematoma or soft tissue debris, gentle scraping movements 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 curette. During the entire operation, the position and operation of the curette should be flexibly adjusted in combination with real-time observation of the endoscope to achieve the best surgical effect.
