This set of detachable dilators is specially matched with the DELTA large-channel minimally invasive spine system. The kit contains multiple specifications of different diameters. During surgery, soft tissues can be expanded step by step from thin to thick to establish large-size working channels gradually, lowering risks of soft tissue laceration and bleeding.

It features a detachable split structure for easy assembly and disassembly. Surgeons can switch sizes as needed intraoperatively. After surgery, splitting the dilator allows thorough cleaning without blind spots, preventing residue of bone fragments and tissue debris.
