Structural features and advantages
Advantages of optical design
Color uniformity: The new generation of optical design fully considers the water environment in spinal endoscopic surgery to ensure uniform color in an environment full of flushing fluid. This allows doctors to more accurately distinguish the color differences of different tissues in the surgical area, such as clearly distinguishing normal tissues, pathological tissues (such as protruding nucleus pulposus, inflammatory tissues), and blood vessels, etc., which helps to accurately determine the location and scope of surgical operations.
Uniform light transmission and avoidance of stray light and astigmatism: The rod mirror uses a new generation of materials developed in China, and through magnetron sputtering coating and anti-reflection film technology, the light transmission of the mirror is more uniform, effectively avoiding stray light and astigmatism. During the operation, good light transmission can provide a brighter and clearer field of view, reduce visual interference caused by uneven light or stray light, and allow doctors to clearly see the subtle structures inside the spine.
Low distortion rate and wide-angle objective lens design: The 30-degree low distortion rate wide-angle objective lens uses a new bonding technology to make the imaging more uniform. The wide-angle design can expand the field of view, allowing doctors to observe more surgical areas without frequently changing the lens angle. A low distortion rate ensures the authenticity of the image so that the image seen by the doctor is consistent with the actual tissue morphology and position, which helps to perform the operation more accurately.
Compatibility advantage
The endoscope connector is compatible with multiple brands of cameras such as STORZ, Wolf, and Olympus, which provides great flexibility for the selection of surgical equipment. Hospitals can choose cameras of different brands to use with the observation imaging mirror based on their existing equipment or economic considerations without worrying about compatibility issues.
Multiple field of view design
Provide multiple field-of-view angles such as 0 degrees, 15 degrees, 30 degrees, and 70 degrees. The 0-degree field of view is suitable for observing the tissue in front, which is very useful when a specific plane structure of the spine needs to be accurately observed, such as checking the flatness of the vertebral plate and the frontal situation of the intervertebral disc. The 15-degree and 30-degree field of view angles can provide a certain angle of observation while taking into account a certain field of view, which can better observe the side structure and depth relationship of the tissue. The 70-degree field of view has a wider field of view and is suitable for overall observation of the surgical area, such as when looking for free nucleus pulposus fragments or evaluating the overall picture of the surgical area.
Application scenarios in spinal surgery
Application in intervertebral disc surgery
In unilateral double-channel spinal endoscopic surgery for intervertebral disc herniation, the internal structure of the intervertebral disc can be clearly seen by observing the imaging mirror with a suitable field of view (such as 30 degrees). The doctor can accurately locate the position, size, and shape of the protruding nucleus pulposus, as well as the relationship between the nucleus pulposus and the surrounding annulus fibrosus and nerve roots. During the nucleus pulposus removal process, good color uniformity and imaging uniformity are used to distinguish between normal annulus fibrosus tissue and diseased nucleus pulposus tissue, and the surgical instruments are accurately used to remove the nucleus pulposus to avoid unnecessary damage to the surrounding tissues.
Application in spinal canal decompression surgery
In spinal stenosis surgery, a mirror with a 70-degree field of view can be used to comprehensively observe the spinal canal and understand the degree and range of spinal canal stenosis. Then, through the mirror with a 0-degree or 15-degree field of view, carefully observe the parts that need decompression, such as hypertrophy of the yellow ligament and bone hyperplasia of the vertebral lamina. By using its color uniformity in the water environment, the yellow ligament, bone, and nerve tissue can be clearly distinguished. When removing the yellow ligament and grinding the bone, the scope of surgery can be accurately controlled to ensure the decompression effect while avoiding nerve damage.
Application of spinal fusion surgery
During spinal fusion surgery, the observation imaging mirror can be used to observe the preparation of the fusion site. For example, through a mirror with a 30-degree field of view angle, check whether the treatment of the facet joint is appropriate, and use color uniformity and imaging uniformity to judge the flatness and cleanliness of the bone surface. When implanting a fusion device, a 0-degree field of view angle can help doctors accurately place the fusion device in the appropriate position, and at the same time, by observing the surrounding tissue, ensure that the fusion device fits well with the surrounding bone tissue and does not compress the nerves.
Operation precautions and tips
Operation precautions
Before surgery, make sure that the observation imaging mirror is correctly and stably connected to the selected camera, check whether the optical system is clear, and avoid affecting the surgical field of view due to poor connection or blurred lens. During the operation, pay attention to protecting the lens of the mirror and avoid collision or scratching, because any damage to the lens may affect its optical performance. At the same time, according to the surgical steps and observation needs, reasonably select the field of view angle, and pay attention to the accuracy of the operation when switching the field of view angle to avoid visual confusion caused by sudden changes in the field of view angle.
Operation skills
Field of view adjustment skills: According to the surgical site and observation focus, skillfully switch to different field of view angles. When you need to observe details, use a smaller field of view angle (such as 0 degrees or 15 degrees), aim the lens at the target tissue, and use the focusing function of the mirror to make the image clear. When you need to observe the whole, switch to a larger field of view angle (such as 70 degrees) to quickly understand the overall picture of the surgical area.
Imaging optimization tips: Since the optical performance of the mirror performs well in a water environment, during surgery, it is necessary to reasonably use flushing fluid to keep the surgical area clean and moist to obtain the best color uniformity and imaging effect. At the same time, when using other surgical instruments, be careful to avoid the instruments blocking the lens and affecting the field of vision. If stray light or astigmatism is found to interfere with the vision, you can slightly adjust the angle of the mirror or check the position of the light source to obtain a purer surgical field of view.
