Embodiment Construction

[0162] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0163] It should be noted that when a component is said to be "connected" to another component, it may be directly connected to the other component or intervening components may also exist. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time.

[0164] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary s...

Abstract

The invention discloses a sheath core assembly, a sheath tube assembly, a sheath tube, a sheath tube processing method and an interventional instrument conveying system and method. The sheath core assembly used for conveying an interventional instrument comprises a core tube and a locking piece fixed to the far end of the core tube and used for being connected with the interventional instrument, and the sheath core assembly further comprises a bending adjusting tube arranged on the periphery of the core tube in a sleeving mode, the far ends of the bending adjusting pipe and the core pipe are fixedly connected with each other, and the near ends of the bending adjusting pipe and the core pipe can slide relatively.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a sheath tube and a sheath tube assembly that facilitate the delivery of interventional instruments. Background technique [0002] The interventional device delivery system generally includes a sheath core assembly and a sheath tube slidingly sleeved outside the sheath core assembly. The two constitute the sheath tube assembly and the distal end can enter the vascular system of the human body. Due to the tortuous nature of the tube system and the consideration of long-distance operation, it is necessary to adjust and control the direction of the distal end so that it can move to the target position. In this way, more mechanical performance requirements are put forward for the sheath, such as taking into account the axial support and bending compliance, etc. In addition, the location and method of applying force during bending adjustment also affect the saf...
