Conveying device and conveying system

Abstract

The invention discloses a conveying device which comprises a guide tube assembly and a control assembly, wherein the control assembly is arranged at the rear end of the guide tube assembly; the control assembly comprises a first control mechanism; the first control mechanism comprises a hollow shell and a limiting unit; the limiting unit comprises a limiting part and a hollow accommodation part; the accommodation part is arranged in the shell; an axial groove and a circumferential groove are formed in the outer surface of the accommodation part; the limiting part penetrates through the shell and is accommodated in the axial groove or the circumferential groove, and then the shell can be axially moved or circumferentially rotated; and the limiting part is further driven by the shell to moveaxially or rotate circumferentially. By adopting the conveying device and a conveying system disclosed by the invention, a first control part is arranged, and a connecting guide tube in the guide tube assembly connected with an implant can be directly controlled to be rapidly switched to circumferential movement from axial movement, so that accurate and reliable implant release positions can be achieved, the implant can be tightly adhered to tissue, and the risk of perivalvular leakage can be reduced.

Description

technical field

[0001] The invention relates to the field of interventional medicine, in particular to a delivery device and a delivery system. Background technique

[0002] The human heart is divided into four chambers, each with its own "outlet," and a total of four valves (mitral, aortic, pulmonary, and tricuspid) that ensure the Blood can flow in the designated direction in the cardiovascular system. The mitral valve is located between the left atrium and the left ventricle. The normal mitral valve ensures blood circulation from the left atrium to the left ventricle and prevents blood from flowing back from the left ventricle of the heart to the left atrium. The occurrence of various heart diseases or degenerative diseases may lead to mitral valve dysfunction, making the mitral valve become abnormally narrowed or dilated. The loss of mitral valve function will affect the normal work of the heart, resulting in gradual weakness or life-threatening.
