Using a syringe as tubular retractor and working channel in minimally invasive cranial and spinal neurosurgery

Abstract

Minimally invasive spinal and cranial neurosurgery often requires tissue retraction. However, excessive tissue retraction is contrary to the principles of minimally invasive neurosurgery. Therefore, any retractor used should be small and atraumatic. Circular plastic retractors made from syringes of various sizes meet these requirements. We report a case series of patients with various cranial and spinal pathologies who underwent surgeries using "self-made" retractors made from plastic syringes of various sizes (2 mL, 5 mL, and 10 mL). All surgeries were performed via minimally invasive approaches. In all cases, the goals of surgical treatment were achieved with no neurological deficits. The use of "self-made" plastic retractors can be helpful in spinal and cranial minimally invasive neurosurgery. Making retractors from plastic syringes and using them is not labor-intensive. This method can extend the possibilities of the neurosurgeon, especially in the field of minimally invasive neurosurgery. Clinical trial number: Not applicable.
