Application of spinal fusion surgery
Use the bone grafting funnel to smoothly inject bone: Intervertebral fusion bone grafting: In intervertebral fusion surgery of the cervical, lumbar or thoracic spine, the bone grafting funnel plays a key role. After the discectomy and intervertebral space preparation are completed, the bone grafting funnel is inserted into the intervertebral space through the UBE surgical channel. The doctor can slowly inject the pre-prepared bone grafting material (such as autologous bone, allogeneic bone or artificial bone) into the intervertebral space through the funnel. For example, in the lumbar L4-L5 intervertebral fusion surgery, the use of the bone grafting funnel can ensure that the bone grafting material is evenly distributed in the intervertebral space, fill the gap caused by the discectomy, promote the bone fusion between the upper and lower vertebrae, and restore the stability of the spine.
Posterolateral fusion bone grafting: For posterolateral spinal fusion surgery, such as posterolateral lumbar intertransverse process fusion, the bone grafting funnel can accurately place the bone grafting material on the bone grafting bed around the transverse process. Guide the funnel to the intertransverse process area through the UBE channel, inject the bone grafting material, and provide sufficient bone volume for bone fusion between the transverse processes. This helps increase the stability of the spine, especially when treating spondylolisthesis or degenerative spinal diseases, and improves the long-term effect of the surgery.
Bone defect repair application
During spinal surgery, such as laminectomy or vertebral fracture surgery, bone defects may occur. The bone graft funnel can be used to fill these bone defects with bone graft material. For example, after cervical laminectomy and decompression, if the lamina defect is large, it may affect the stability of the spine. Filling the lamina defect with bone graft material through the bone graft funnel can promote the repair of bone defects and reduce the occurrence of complications such as postoperative spinal deformity.
Operation precautions and skills
Operation precautions
Channel preparation and instrument insertion: Before using the bone graft funnel, make sure that the UBE surgical channel has been fully established and unobstructed. When inserting the bone graft funnel, be careful to avoid damaging the tissues around the channel, especially nerves and blood vessels. The funnel can be inserted slowly and gently into the target bone graft position under the guidance of an endoscope.
Bone graft material preparation and characteristics: Choose the appropriate bone graft material according to the specific needs of the operation, and understand its particle size, fluidity and other characteristics. If the bone graft material particles are too large, it may block the funnel; if the fluidity is too strong, it may cause uneven distribution of the bone graft material. At the same time, ensure that the bone graft material is strictly disinfected and processed to avoid infection.
Avoid overfilling: During the bone grafting process, avoid overfilling the bone graft material. Overfilling may cause the bone graft material to overflow and compress surrounding tissues, such as nerves and blood vessels. The doctor needs to reasonably control the amount of bone grafting according to the size and shape of the bone defect and the feedback of the bone graft funnel.
Operation skills
Insertion skills: According to the anatomical path displayed by the endoscope, the bone graft funnel is inserted at a suitable angle and direction. During the insertion process, the tip of the funnel can be inserted into the surgical channel first, and then gradually pushed, while using the slender shape of the funnel to advance along the natural anatomical gap or the established channel. If you encounter resistance, do not force it in, check the cause and adjust the insertion angle or position.
Bone grafting skills: When injecting the bone graft material through the funnel, use a slow and steady method. According to the size and shape of the bone grafting site, the position and angle of the funnel can be appropriately adjusted to ensure that the bone graft material is evenly distributed in the target area. If you find that the bone graft material does not flow smoothly, you can gently shake the funnel or use appropriate tools (such as a push rod) to assist in the injection of the bone graft material, but pay attention to the operating force to avoid damaging the funnel or affecting the distribution of the bone graft material.
