For periodic acute injections using a syringe. A recessed top assists in guiding the syringe needle into the cannula. The recess makes this unit unsuitable for use with an Internal.
A stop can be put on the needle so that it penetrates to the exact depth with each injection. After each injection, a Dummy can be inserted to prevent tissue entry.
The unit consists of a threaded cylindrical plastic pedestal molded around a piece of stainless steel tubing that extends below the pedestal. The pedestal is secured with cranioplastic cement and mounting screws.
A polyester mesh option is also available if needed as an attachment to the guide pedestal.
A special Internal has been made for the C315GA only (our C315IA ).
Pedestal Height: 8. 0 mm (.315").
Pedestal Diameter: 3.5 mm (.138").
