Description

A kind of Use of Neuronavigation lower ventricle puncture drainage tube

Technical field

The utility model relates to a kind of Use of Neuronavigation lower ventricle puncture drainage tubes in medical instruments field.

Background technique

Ventricular drainage operation is a kind of common operation of neurocranial surgery, its object is to: 1. release cerebrospinal fluid are alleviated because of brain Ponding causes serious increased intracranial pressure；2. blood contained cerebrospinal fluid can be drained for the patient of ventricular hemorrhage, mitigate ventricles of the brain stimulation and prevented Only ventricular system is blocked；3. Encephalocele discharges cerebrospinal fluid, it is more advantageous to appearing for surgical field of view；4. being injected into the ventricles of the brain positive Contrast medium or gas do ventriculography；5. draining inflammatory cerebrospinal fluid, or antibiotic treatment ependymitis is injected into the ventricles of the brain；6. to Injection indicarminum or phenol sulphonide in the ventricles of the brain, identification are that hydrocephalus is communicating or obstructive；7. doing ventriculo-peritoneal shunt hand Art places various isocons；8. leaving and taking cerebrospinal fluid does routine and biochemical analysis etc.；It clinically mostly uses outside traditional ventricles of the brain at present Surgical drainage and the operation of ventriculoscope lower ventricle external drainage；Traditional extraventricular drainage operation the disadvantage is that, operator can only according to from Oneself clinical experience operates, and in surgical procedure, operator cannot intuitively see the position of patient's ventricles of the brain, cannot accurate handle Hold the direction and depth of puncture；Often cause to puncture repeatedly because puncture path is incorrect, to aggravate real to patient's brain The damage of matter；As puncture position is too deep, it is likely that wear out septum pellucidum or penetrate to telocoele or because drainage tube ventricles of the brain end is tight It pastes ventricles of the brain wall and inadequate drainage is led to by choroid plexus package；The shortcomings that ventriculoscope lower ventricle external drainage is performed the operation: although ventriculoscope can With help operator accurately hold puncture depth, avoid drainage tube ventricles of the brain end adherent or wrapped up by choroid plexus, but with it is traditional Extraventricular drainage operation is the same, and ventriculoscope lower ventricle external drainage, which is performed the operation, not can accurately grasp the direction of puncture, equally there is puncture Path error and lead to the risk punctured repeatedly.
