Embodiment Construction

[0039] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0040] It should be noted that "distal end" and "proximal end" are used as orientation words, which are commonly used terms in the field of interventional medical devices, where "distal end" means the end away from the operator during the operation, and "proximal end" means The end near the operator during surgery. Axial, refers to the direction parallel to the line connecting the center of the distal end and the center of the proximal end of the medical devi...

Abstract

The invention relates to a conveying device and a conveying system. The conveying device and the conveying system are used for conveying an interventional device. The interventional device comprises connecting parts capable of being connected with the conveying device; the conveying device comprises a connecting assembly and a control assembly, and the connecting assembly comprises a far-end rotating piece and a near-end rotating piece which have the same spin axis; the control assembly is used for driving the far-end rotating piece to rotate relative to the near-end rotating piece around therotating axis; far-end guiding structures and near-end guiding structures are arranged on the far-end rotating piece and the near-end rotating piece around the rotating axis respectively; the far-endguiding structures and the near-end guiding structures are crossed to form locking parts for clamping the connecting parts; when the far-end guiding structures and the near-end guiding structures oppositely rotate around the rotating axis, the locking parts drive the connecting parts to folded or unfolded inwards. The connecting parts are folded or unfolded, medical equipment can be controlled bythe conveying device, it is thus achieved that the interventional device is slowly released, and therefore it is avoided that the medical equipment is rapidly popped up when being released from the far end of the conveying device to influence on the releasing effect.

Description

technical field [0001] The invention belongs to the technical field of interventional medical devices, and relates to a delivery device and a delivery system comprising the delivery device. Background technique [0002] Percutaneous interventional technology is a disease treatment method that has developed rapidly in recent years, and its applicable fields are becoming more and more extensive. Using catheter interventional therapy, various materials, devices and drugs can be implanted into the human heart, arteriovenous blood vessels; such as vascular stents, heart valves, heart defect occluders, vascular plugs, vascular filters, etc. [0003] At present, when placing these interventional medical devices into the heart and arteriovenous vessels of the human body through catheter intervention, due to the complex anatomical structure of the human heart and arteriovenous vessels, to ensure that the interventional medical devices accurately reach the predetermined position, deli...
