Description

Technical Field

[0001] The invention relates to a surgical tool storage and ejection device, in particular to a spinal surgical tool storage and ejection device, and belongs to the technical field of medical devices. Background Art

[0002] Spinal surgery is often complicated and requires a lot of instruments, especially lamina rongeurs and nucleus pulposus forceps, which are used most frequently. Due to the different anatomical spaces and lesion levels of different surgical sites, different types of lamina rongeurs and nucleus pulposus forceps need to be used alternately in the same operation. However, the space on the surgical instrument cart is limited, and the used lamina rongeurs and nucleus pulposus forceps are often piled together. If they need to be used again, doctors and nurses cannot find the surgical instruments quickly, which delays the operation time and even causes the instruments to fall and be contaminated when searching. In spinal surgeries abroad, nurses put such surgical instruments vertically into a storage box with gauze in the middle. Although it can separate surgical instruments, it is still necessary to search for a specific model of instrument when using it, which is very inconvenient. In addition, gauze pads need to be made as separators for each operation, which consumes precious surgical time. Summary of the invention
