Problems solved by technology

[0005] One of the solutions in the existing technology is to implant an atrial shunt device, but at present there is a lack of delivery devices for atrial shunts, especially the equipment for automatically delivering separators. For this reason, it is necessary to improve it. In order to overcome the deficiencies in practical application

Embodiment 1

[0042] like Figure 1-11 As shown, the present embodiment provides a delivery system for an atrial shunt based on electric control, including a first sheath structure 101, a second sheath structure 102, an inner core tube structure 103 and an electric control assembly, and the second sheath structure 102 It is connected to the first sheath structure 101 and the inner core tube structure 103, the inner core tube structure 103 is connected to the atrial shunt 104, the second sheath structure 102 and the inner core tube structure 103 are respectively installed with electric control components, and the first sheath structure 101 is used for atrium The second sheath structure 102 is used to constrict the atrial shunt 104; the atrial shunt 104 reaches the atrial septum and is released by adjusting the electronic control assembly.

[0043]Specifically, the delivery system 100 for the atrial shunt can help to put the atrial shunt 104 through the "transseptal technique" technique (that...

Embodiment 2

[0066] An electronically controlled delivery system for an atrial shunt in this embodiment differs from Embodiment 1 in that:

[0067] In this example, an atrial shunt catcher is added to the inner core tube structure 103 , which can be used to help recover and replace the atrial shunt 104 , and the catcher adopts a clamping method to catch and fix the atrial shunt 104 .

[0068] For other specific structures and specific implementation steps, please refer to Embodiment 1.

Embodiment 3

[0070] An electronically controlled delivery system for an atrial shunt in this embodiment differs from Embodiment 1 in that:

[0071] In this example, the inside of the inner core tube 132 is changed to be hollow, and the wire harness end of the atrial shunt is loaded into the inner core tube 132 by hydraulic suction, and the atrial shunt 104 is released by liquid mechanical pressurization at the tail of the inner core tube 132 .

[0072] For other specific structures and specific implementation steps, please refer to Embodiment 1.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an atrial shunt conveying system based on electric control. The atrial shunt conveying system comprises a first sheath structure, a second sheath structure, an inner core tube structure and electric control assemblies; the second sheath structure is connected with the first sheath structure and the inner core tube structure, and the inner core tube structure is connected with an atrial shunt; the second sheath structure and the inner core tube structure are provided with the electric control assemblies respectively; the first sheath structure is used for atrial septum puncture reaming, and the second sheath structure is used for collecting the atrial shunt; and the atrial shunt reaches the atrial septum and is released by adjusting the electric control assemblies. According to the system, automatic adjustment can be realized to improve the positioning precision, and manual fine adjustment is also considered to realize accurate positioning, accurate release and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an electric control-based delivery system for an atrial shunt. Background technique [0002] Heart failure (heart failure) referred to as heart failure refers to the failure of the venous blood to fully discharge the heart due to the dysfunction of the systolic function and / or diastolic function of the heart, resulting in blood stasis in the venous system and insufficient blood perfusion in the arterial system, resulting in Cardiac circulatory disorder syndrome, which is characterized by pulmonary congestion and vena cava congestion. Heart failure is not an independent disease, but the end stage of the development of heart disease. The vast majority of heart failures begin with left heart failure, that is, the first manifestation is pulmonary circulation congestion. [0003] Heart failure is mostly characterized by reduced cardiac output. In this setting, t...
