Title:
BENDING-ADJUSTABLE CATHETER
Document Type and Number:
WIPO Patent Application WO/2023/240787
Kind Code:
A1
Abstract:
A bending-adjustable catheter, comprising a handle (10), a catheter body (20) and a bending adjustment line (30), wherein a proximal end of the catheter body (20) is mounted on the handle (10). The bending-adjustable catheter is provided with a guide channel penetrating the handle (10) and the catheter body (20). The catheter body (20) is provided with a proximal-end main body section (21) and a distal-end bending adjustment section (22). The distal-end bending adjustment section (22) comprises a first section (221) and a second section (222), wherein the second section (222) is connected to a distal end of the proximal-end main body section (21); the first section (221) is connected to a distal end of the second section (222); and the hardness of the distal-end bending adjustment section (22) is less than the hardness of the proximal-end main body section (21). A distal end of the bending adjustment line (30) is fixed to the distal-end bending adjustment section (22), and a proximal end thereof is connected to the handle (10). By operating the handle (10), the bending adjustment line (30) can be controlled to adjust the bending angle of the distal-end bending adjustment section (22). An operator can operate the handle (10) to adjust the angle of the distal-end bending adjustment section (22), so as to adjust the coaxial state of a distal end of the catheter body (20) and an implant position, so that an instrument can be implanted into a preset position in a relatively adaptive state after being pushed out from the distal end of the catheter body (20), thereby improving the implantation effect.
