The medical fluid injection hole that the first cavity and the second cavity communicate is stated, the medical fluid injection hole is disposed in proximity to the rear sealing cover side
Outer catheter two sides in, be provided with connection interface tube at the medical fluid injection hole.
Further, a kind of conduit for neurosurgery described in the utility model, wherein the outer catheter, inner catheter
It is made with reinforcer using polyurethane or polythene material one-pass molding.
Using a kind of conduit for neurosurgery described in the utility model, cooling can be rinsed by inner catheter
Operation will connect external sterile saline, due to being provided with several sprays on the head of medical silica-gel syringe pipe by connector sleeve
Hole is drenched, then sterile saline rinsed on a large scale through the outflow of spray apertures 8, cooled down, while improving efficiency, can effectively prevented
It stops loss and hurts surrounding tissue, it is lower that security risk is caused to patient.Furthermore it is also possible to drug therapy is carried out by outer catheter, it can be with
External medical fluid is connected by connection interface tube, the first liquid medicine is injected into the first cavity by medical fluid injection hole, is infused
The medical fluid entered penetrates into hole outflow by the medical fluid being located on preceding sealing cover, carries out relative medicine treatment to patient, meanwhile, when patient needs
When injecting second of liquid medicine, second of liquid medicine can be equally injected into the second cavity by medical fluid injection hole,
Carrying out relative medicine treatment to patient also can effectively avoid two kinds of liquid medicines while realizing patient medication
After sharing conduit, and liquid medicine is caused to influence each other, to influence the performance of liquid medicine drug effect.It is described in the utility model
Conduit has structure simple, and reasonable design, easy operation, advantage low in cost and safe and practical is conducive to promote the use of.
