An instrument channel that can achieve multi-angle deformation

Abstract

The utility model relates to a kind of instruments passageways that can realize multi-angle deformation, for with hard core pole cooperation to be used as puncture device, main body is deformable sheath;The deformable sheath includes sheath head, flexible sheath and sheath tail sequentially connected from top to bottom, and flexible sheath is made of soft material;The inner wall of the flexible sheath is attached with several sheath support rings arranged sequentially from top to bottom. It has the unique advantage of super-large bendable angle. During the operation, the operator can adjust the position and direction of the instrument according to the actual scene requirements, and is not affected by the traditional puncture sheath straight-in straight-out form. It can be adjusted to the specified position more flexibly during the operation, thereby reducing the difficulty of the operation and shortening the operation time.
