CONTROL HANDLE, BENDING CONTROL LINE AND IMPLANT DELIVERY DEVICE

WIPO Patent Application WO/2022/233104

A1

A control handle (1), a bending control line (21) and an implant (3) delivery device. The control handle (1) comprises: a base portion (11) and a rotating portion (12), wherein the base portion (11) is used for being connected to a bending control tube (22) of a catheter assembly (2), and an axial direction of the base portion (11) is the same as an axial direction of the bending control tube (22); the rotating portion (12) is rotatably connected to the base portion (11) in a radial direction of the base portion (11), and a rotation axis of the rotating portion (12) and an axis of the base portion (11) are located in different planes; and the rotating portion (12) is used for being fixedly connected to a proximal end of the bending control line (21), and is used for driving, by means of rotation, the bending control line (21) to be wound around same. The rotation axis of the rotating portion (12) and the axis of the base portion (11) are configured to be located in different planes, such that when the rotating portion (12) rotates, the bending control line (21) is wound around same, thereby realizing bending control, and thus reducing the length of the control handle (1) and making the structure more compact. By means of adjusting the size of the rotating portion (12) around which the bending control line (21) is wound, the transmission ratio may be adjusted, and thus the bending control rate is adjusted.
