UBE surgical tools-final processor intervertebral system reamer

Structural features and advantages
Multiple specifications to choose from
Various reamer specifications from 7MM to 14MM are provided. This rich range of sizes can meet the endplate processing of different spinal parts and different surgical needs in UBE surgery. For example, in cervical spine surgery, due to the relatively small cervical vertebral body, a 7MM-9MM reamer may be selected to finely process the endplate to avoid excessive damage to the surrounding nerves and blood vessels; while in lumbar spine surgery, for larger vertebral bodies and wider endplate areas, a 10MM-14MM reamer can complete the task more efficiently and ensure the comprehensiveness and accuracy of endplate processing.
Quick-release structure handle matches reamer
The quick-release structure handle is a practical design that can quickly and conveniently replace reamers of different sizes. In UBE surgery, the surgical process may require the size of the reamer to be adjusted at any time according to actual conditions. This quick-release structure can greatly save surgical time and improve surgical efficiency. Doctors can quickly switch to the appropriate reamer under uncomplicated operations to adapt to the endplate processing work at different stages, making the surgical process smoother.
Unique bilateral cutting design
The unique cutting method on both sides of the reamer, with one-knife precision carving and good sharpness, brings significant advantages to the endplate processing. When processing the endplate, the sharp blade can easily remove the cartilage tissue, sclerosis layer and other pathological tissues on the surface of the endplate, making the surface of the endplate smoother and rougher, which is conducive to the subsequent bone graft fusion. Compared with the traditional single-edge or ordinary cutting method, bilateral precision cutting can achieve a more refined cutting effect in one operation, reduce unnecessary damage to the endplate, and improve processing efficiency.
Application scenarios in UBE surgery
Cervical fusion surgery
In anterior cervical fusion surgery, the UBE surgical channel is first established through a minimally invasive incision, and then a reamer of appropriate specifications (such as 7MM - 9MM) is selected according to the actual situation of the cervical vertebral endplate. Use a reamer with bilateral precision cutting to carefully process the endplate. Due to the rich nerves and blood vessels around the cervical spine, the sharpness and accuracy of the reamer are crucial. It can accurately remove the pathological tissue on the surface of the endplate while protecting the surrounding important structures. For example, when processing the endplate of the C4-C5 or C5-C6 cervical vertebrae, the doctor can use the visualization of the UBE endoscope to use a reamer to process the endplate surface just right, creating good conditions for the implantation of the fusion device, promoting bone fusion, and improving the stability of the cervical spine and the patient's quality of life.
Lumbar fusion surgery
In posterior lumbar fusion surgery, larger reamer (such as 10MM-14MM) plays an important role. After the pedicle screw fixation is completed, the endplate of the intervertebral space needs to be fully prepared. Use the quick-release structure handle to quickly install the appropriate reamer to process a large area of ​​the lumbar vertebral endplate. The bilateral blade design can quickly and effectively remove the cartilage and sclerosis layer on the endplate so that the endplate surface forms a microstructure suitable for bone graft fusion. For example, in fusion surgery of lumbar segments such as L4-L5 or L5-S1, precise endplate processing can increase the contact area and stability between the fusion device and the endplate, thereby improving the success rate of lumbar fusion surgery, reducing the patient's waist pain and improving lumbar function.
Thoracic fusion surgery
In thoracic fusion surgery, due to the relatively special anatomical structure of the thoracic spine and the protection of the surrounding ribs and thorax, the surgical operation space is relatively limited. According to the size of the thoracic vertebral body and surgical needs, select a reamer of appropriate specifications (such as 8MM-12MM). Under the visual conditions of UBE surgery, use the sharp blade of the reamer to process the endplate, remove the diseased tissue, and create a good foundation for bone grafting and fusion device implantation. Whether in fusion surgery after treating thoracic fractures or in fusion surgery for correction of thoracic deformity, this reamer can accurately complete the endplate processing work in a limited space, which helps to stabilize the thoracic segment and improve the patient's thorax and spinal function.
Operation precautions and skills
Operation precautions
Before surgery, carefully evaluate the size, shape, and degree of lesions of the spinal endplate according to the patient's preoperative imaging data (such as X-rays, CT, etc.), so as to select a reamer of appropriate specifications. During the insertion and operation of the reamer, pay close attention to the image under the UBE endoscope to ensure that the position and direction of the reamer are accurate to avoid damaging the surrounding nerves, blood vessels, and other important tissues. Because the reamer has a high sharpness, pay attention to controlling the force during operation to prevent excessive cutting from causing endplate fracture or perforation, affecting the surgical effect and patient prognosis.
Operation skills
Insertion skills: According to the anatomical structure of the surgical site and the position of the UBE surgical channel, slowly insert the reamer into the surgical site at an appropriate angle and direction. During the insertion process, the guidance of the endoscope can be used to prevent the reamer from colliding with surrounding tissues. If resistance is encountered, do not force insertion. Check the cause and adjust the insertion angle or choose a more appropriate reamer size.
Cutting skills: When using a reamer to process the endplate, use a uniform and gentle cutting action. According to the hardness and lesion of the endplate, adjust the cutting force and speed appropriately. For harder lesions, the force can be slightly increased, but care should be taken to avoid sudden excessive force. At the same time, the characteristics of double-sided fine carving should be fully utilized. By rotating the reamer, the blades on both sides can effectively cut the end plate to achieve a uniform and fine treatment effect. During the cutting process, the debris on the reamer should be cleaned regularly to maintain cutting efficiency and avoid debris residue affecting the surgical field of view and subsequent operations.
