The invention discloses a minimally-invasive transcranial hard passage guide device. A user may: integrally implant a transcranial support sheath with a cranial bit into cranium; extract the cranial bit; place a blue tube with a transparent tube and a blunt-head needle core into the transcranial support sheath; bring the transcranial support sheath to a focal target; extracting the blunt-head needle core; close the top end of the blue tube which has a side hole in the bottom end such that a drain tube can be used to suck hematoma, effusion and the like through the side hole. During hematoma and effusion extracting, the user also may: open the top end of the blue tube; pass a drug administering device through the blue tube and out of the blue tube; use a syringe and the drug administering device or an irrigator to perform melt-washing equivalent circulatory drainage on the inside of the cranium; extract the blue tube; place an neuroendoscope or other auxiliary devices inside through a transparent tube in the transcranial support sheath. The minimally-invasive transcranial hard passage guide device has the advantages that surgeries can be visually operated, and reverse graduation marks on the transaprent tube brings conveniences of use to surgeons.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a guide device for a minimally invasive cranial penetrating hard channel. Background technique [0002] When the patient has intracranial hematoma, cerebral hemorrhage, or hydrocephalus, the patient needs to be treated, that is, the intracranial hematoma and hydrocephalus need to be removed, and the intracranial hematoma and hydrocephalus need to be removed with a suction catheter. However, the existing transcranial support sheath suction catheter can only extract intracranial hematoma, hydrops, etc., and cannot realize visual operation during the extraction process, and there are channel injuries and inaccurate targets for entering the lesion, which is inconvenient for doctors to use. . Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a minimally invasive transcranial hard ...
