[0003] In the Chinese patent with the publication number CN209474580U, an adjustable neuroendoscope-assisted sheath tube is mentioned, which includes a sheath tube, a hollow sheath core, and a sheath handle connected to the sheath tube; the sheath tube is composed of a first C-shaped sheath tube and a second C-shaped sheath tube, and the first C-shaped sheath tube and the second C-shaped sheath tube are detachably and fixedly connected, and a sheath tube channel is formed between the first C-shaped sheath tube and the second C-shaped sheath tube. The structure of the utility model is reasonable and simple, easy to manufacture, and convenient to use. Through the utility model, the size adjustment of the sheath tube channel between the first C-shaped sheath tube and the second C-shaped sheath tube is realized.

[0004] However, the above-mentioned device and the current existing neuroendoscope sheath sets are mostly rigid working sheath sets. When removing intracranial hematomas, especially a large amount of hematomas, a larger working space needs to be obtained by adjusting the position of the sheath set. Due to the relatively hard texture of the sheath set, additional damage to the brain tissue may occur.

[0005] Therefore, those skilled in the art have proposed a composite neuroendoscope-assisted sheath set to solve the above-mentioned problems. Content of the Utility Model
