The Two-ferrule Cannula provides two implantable fibers, each within its own ferrule, at a precise distance exceeding 1.7 mm.
###: Correspond to the fiber length specified in the ordering code generator section.
→ 상품 상세 정보 : Two-ferrule Cannulas
The Two-ferrule Cannula provides two implantable fibers, each within its own ferrule, at a precise distance exceeding 1.7 mm. The tolerance on the protrusion for each fiber is less than 0.1 mm. These cannulas are perfectly suited for the applications where two brain centers at a distance larger than 1.7 mm from each other are optically stimulated or controlled. The positioning of one mono fiber cannula at a time with the stereotaxic equipment has a greater likelihood of 3D positioning errors (lateral and depth). With a two-ferrule cannula the insertion of the fiber is faster (single shot), the distance between the fiber tips is predefined and the protrusion depth is assured.
Two types of receptacles are currently available for the Two-ferrule Cannula. They both consist of precision machined holders that house zirconia ferrules and determine the spacing between the ferrule centers. The first type of a two-ferrule cannula connects to a pair of patch cords terminated with 1.25 mm ferrules by using two zirconia sleeves (ID 1.25 mm). In the other case, the holder also includes a pair of magnets, so that the cannula can connect to a pair of rectangular magnetic connectors.
The Two-ferrule Cannula can be made for distances larger than 1.7 mm. For shorter distances between the brain centers, please refer to Dual Fiber-optic Cannulas.
