CATHETER STRUCTURE OPERATION

摘要

PURPOSE: A catheter operating structure is provided to make forward and backward movement of a catheter possible through simple rotation. CONSTITUTION: A catheter operating structure comprises a rotating member(10), a drive member(20), and an injection nozzle moving member. In the rotating member, a helical shaft inserted into a pipe shaped body is formed. The drive member is formed in a shape that is divided in the longitudinal direction and is combined in a structure that is assembled and disassembled like the body. The injection nozzle moving member moves in the longitudinal direction of the drive member.
