Background

Lumbar intervertebral space infection is always a troublesome problem in spinal surgery, and along with popularization of spinal endoscopes, the treatment method for intervertebral space flushing under the intervertebral foramen endoscope can effectively treat the intervertebral space infection, and as shown in fig. 1, two drainage tubes are placed in the operation to finish drainage in the intervertebral space.

However, lumbar intervertebral space infection belongs to deep tissue infection, simple primary intervertebral foramen mirror operation flushing is far insufficient, intervertebral space drainage flushing is often carried out again after intervertebral foramen mirror operation, but a drainage tube which is placed in operation and used for intervertebral space drainage flushing is difficult to continue to be used all the time after operation, and the main frequent occurrence is a duplug and leakage; thus, medical personnel are required to pay attention to and handle the drainage and irrigation process at any time.

Based on the above-mentioned use scenario, there is no special irrigation drainage tube for intervertebral space irrigation at present, and it is summarized that such drainage tube needs to meet the following requirements: firstly, in the current operation scheme, only one intervertebral foramen mirror pipeline can be used for placing drainage consumable materials, if no additional incision is added, the drainage pipe and the flushing pipe are required to be placed in the intervertebral foramen mirror pipeline, so that the placed pipeline needs to simultaneously meet the effects of suction and flushing; secondly, the canal of the intervertebral foramen mirror is smaller, and after the drainage tube is placed in a visual state, the lens is withdrawn, so that the overall outer diameter of the placed drainage tube cannot exceed the length of the endoscope of the intervertebral foramen mirror, and the condition that the drainage tube is placed from the intervertebral foramen mirror can be realized; thirdly, because the intervertebral space has a lot of tissues and infected secretions, the suction pipeline mouth is easy to be blocked, so the suction pipe can be dredged, and the suction pipe is particularly used in the postoperative use process.
