Abstract

The invention relates to the technical field of medical apparatus and instruments, in particular to a surgical distractable protective sheath which comprises a first movable plate, a second movable plate, a gantry support and a handle, the bottom of the gantry support is sleeved with the handle, an adjusting knob is arranged on the inner side of the gantry support above the handle, and the second movable plate is arranged at the top end of the gantry support. A threaded rod is further arranged on the surface of the second movable plate, a first movable plate is arranged above the second movable plate, one end of the first movable plate penetrates through the gantry support, the gantry support is rotationally connected with the first movable plate, and outward turning parts are arranged at the ends, close to the gantry support, of the first movable plate and the second movable plate correspondingly; according to the distraction device, the distraction size can be enlarged or reduced, it is guaranteed that the distraction angle can be accurately controlled in the surgical operation process, instruments are prevented from falling off in the surgery, and soft tissue injuries are reduced.

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...
