Electric stent delivery system based on remote control

Abstract

The invention relates to an electric stent delivery system based on remote control. The electric stent delivery system based on remote control comprises a delivery device and a remote control device; the remote control device is composed of a control page and a control device; the delivery device comprises a guide head, an inner core, an outer sheath, a pushing rod, a pay-off device, a wire cutting device, a valve stent traction wire, a take-up device, a pushing rod pushing device, an inner core pushing device and a mounting base; and the control device comprises a main control board, a take-up motor drive, a wire cutting motor drive, a pushing rod motor drive and a power module. The electric stent delivery system has the advantages that the problems of complicated operation, low accuracy and high operation failure rate in an existing mitral valve replacement technology are solved, the trauma of a patient is reduced practically, the difficulty of an operator is reduced, the success rate of an operation is improved, postoperative complications are reduced, the operation process can be simplified, accurate positioning and accurate release of mitral valve placement are ensured, and a contribution is made to the development of the mitral valve replacement technology.

Description

Technical field [0001] The present invention relates to the field of medical devices, and in particular, is a remote control-based electric stent delivery system. Background technique [0002] Mitral Regurgitation (MR) is the most common valve disease. In general, the incidence rate is about 1.7%, and severe MR will seriously damage the heart function, increase the risk of heart failure, and seriously threaten health and life. The main treatment method of severe MR patients is a mitral valve repair or replacement under vitro circulation. The method is prone, the effect is exact, but the risk of patients with unsatisfunction or severe complications, high, high mortality, high mortality, high mortality, high mortality, high mortality, high mortality, high mortality No surgery. For valve replacement means for these patients lack safety, minimally invasive, rapid rehabilitation, only rely on drug conservative treatment, and the prognosis is poor.
