An innovative surgical tool: air jet dissector.
OBJECTIVE
This study aims to demonstrate and test a new surgical tool which is designed and manufactured in our institution for neurosurgical operations. The device is referred as 'air jet dissector'.


METHODS
After fabrication of the device, we tested it on 32 New  Zealand rabbits. The effectiveness of the device was compared with a well-known ultrasonic aspirator (CUSA) in an experimental design of cranial corticotomies. Dissection quality, intracranial hemorrhage, edema formation and astroglial and microglial reactions were compared for both devices.


RESULTS
Regarding post-operative edema formation and intracranial hemorrhage, the air jet dissector was found superior to the CUSA system. Additionally, the pre-operative comfort of the device was also better than the CUSA.


CONCLUSIONS
In our opinion, this new design has a future in neurosurgical  operating rooms. Further refinements and experimental testing is required.
