Patient adaptable cerebellar retractor system: Use in posterior fossa surgery

摘要

A new patient adaptable dual use soft tissue spreader and cerebellar retractor system designed for use during surgery of the posterior fossa is described. We found that this new retractor design allowed for excellent exposure, plus greater freedom and dexterity during the posterior fossa surgery. This novel instrument is an improvement over the existing instrument, because it provided more force/power transmission from pins/connectors to the brain spatula via the shorter flexible arm. Highlights ? A new patient adaptable dual use soft tissue spreader and cerebellar retractor system designed ? New developed retractor is particularly suitable for semisitting position. ? This retractor is suitable for surgical access to lesions of the cerebellopontine angle and fourth ventricle.
