Cylindrical channel retractor for intraventricular tumour surgery--a simple and inexpensive device.

Ventricular tumors are excised using both microscope and endoscope as the viewing device. Excision of these tumors requires corticectomy. After these corticectomies, brain has tendency to fall because of CSF drainage. Currently available retractor systems are fixed and thus can be traumatic. On the other hand few systems that require small corticectomy need stereotactic or navigation system aid. These all methods and equipment are costly. Our simple method of using a cylindrical channel retractor custom made out of 20 cc plastic syringe in OT helps in making minimum possible corticectomy. It gives surgeon minimally traumatic, inexpensive, hands free retractor.
