Problems solved by technology
[0002] In the prior art, neuroendoscopes are commonly used to enter the brain through drilling holes for observation and surgery. However, for suspicious lesion tissues such as intracranial cysts, due to their different chemical properties and different surgical methods, the consequences are also different. Different, relying solely on imaging evidence to make a pathological diagnosis often requires a greater risk

The fluid sucking device for nervous endoscope operation consists of one fine transparent sucking unit and one nerve endoscope tube with set operating channel. The sucking unit has length greater than that of the operating channel of the endoscope and one syringe set in the front end. When the nerve endoscope tube reaches the intracranial tissue and encounters suspicious pathological change tissue, especially cystoid pathological change tissue, the syringe of the sucking unit may be pierced into the tissue to suck the inside matter as sample. This is favorable to determine pathological change property and to decide the operation mode with less medical risk.
Description
technical field [0001] The invention relates to a medical device, in particular to a liquid pumping device for neuroendoscopic surgery. Background technique [0002] In the prior art, neuroendoscopes are commonly used to enter the brain through drilling holes for observation and surgery. However, for suspicious lesion tissues such as intracranial cysts, due to their different chemical properties and different surgical methods, the consequences are also different. Different, relying solely on imaging evidence to make a pathological diagnosis often requires a greater risk. Contents of the invention [0003] The technical problem in the prior art to be solved by the present invention is: since the existing neuroendoscope only has grasping and scissors instruments, it is ideal for solid tumors; Cause chemical encephalitis, the consequence is serious, often need to bear greater risk. The technical scheme adopted by the present invention to solve the above-mentioned technical ...
