Abstract： |
The invention relates to a multi-path nerve-restoring duct, its manufacturing method and special mould. Wherein, the duct is comprised by a chitose round duct and an internal base material with axial multi-path; the mould is formed by a Styrofoam thermal insulation chassis and a stainless steel cover plate while a plurality of cylindrical holes in different inner diameters are regularly arranged on the thermal insulation chassis and a fine needle hole is arranged on the bottom of holes through to the base of chassis. And the manufacturing method of multi-path nerve restoring duct comprises inserting the chitose round ducts in different diameters into the holes of relative diameter of the mould chassis; filling different filling base material into the chitose round ducts according to the demand; using the pre-cooling stainless steel cover plate to quickly cover the chitose round ducts to be stored in low-temperature refrigerator for more than 12 hours; freezing, drying, deacidifying, and poaching with distilled water to the neutral ones; then to be dried in room temperature to attain the multi-path nerve restoring duct. Said manufacturing process is simple with stable result which applies batch production. |
