Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an expandable protective sheath for surgery. Background technique [0002] Lumbar fusion, as the main surgical method for the treatment of spinal instability caused by various factors such as degeneration, trauma, infection, and tumor, has been widely accepted by spinal surgeons. Traditional surgical methods have large soft and bony tissue damage, resulting in Surgical risks are high, postoperative recovery time is prolonged, and original function is impaired. Therefore, minimally invasive techniques that minimize tissue damage while ensuring safe and efficient surgery have become an important development direction in the field of spinal surgery today. [0003] There are various forms of spinal minimally invasive distractors in the current technology, which can ensure the safety and efficiency of the operation while minimizing tissue damage. There are two typical types, o...
