Description

Technical Field

[0001] The utility model belongs to the technical field of neuroendoscopy, and in particular relates to a single-channel multifunctional neuroendoscopy structure. Background Art

[0002] A neuroendoscope is a structure that can expand the surgical angle of view, increase lighting intensity and improve direct vision in the treatment of hypertensive cerebral hemorrhage. It is also minimally invasive, time-saving and has good prognosis. It is an important part of the minimally invasive neurosurgery platform. Among them, the use of neuroendoscopes to treat hypertensive intracerebral hematoma has gradually been adopted clinically due to its advantages of less trauma and more thorough hemostasis. The neuroendoscopes in the prior art have an endoscope rod that is a hard steel structure that cannot be bent or is difficult to bend. When the channel it enters is bent, the rod will rub against the inner wall of the channel, affecting the operation. At the same time, when a neuroendoscope is used for surgery, the surgical field of view is deep, the surgical space is narrow, and it is not easy to move. At the same time, its functions are relatively limited, and it cannot simultaneously have the function of draining blood and water, which will also affect its ease of use, and its applicability and practicality are limited.
