Problems solved by technology

[0005] One of the solutions in the existing technology is to use an alloy shunt device. This method has been clinically proven to be effective, but the existing structure and performance need to be further optimized. The overall strength of these devices is too high to facilitate the operation of the conveyor. At the same time, it is easy to endothelialize after being placed in the atrium, resulting in the opening being blocked

Embodiment 1

[0035] Such as Figure 1 to Figure 4 As shown, the present embodiment provides an atrial shunt decompression device, which is connected to a conveyor, and the shunt decompression device includes a wire harness collector 101, a left atrium wall fixing structure 102, a middle connecting channel 103 and a right atrium The wall fixing structure 104, the left atrium wall fixing structure 102 and the right atrium wall fixing structure 104 communicate with each other through the middle connecting channel 103, and the left atrium wall fixing structure 102 and the right atrium wall fixing structure 104 are arranged symmetrically on both sides of the middle connecting channel 103. side, the height of the middle connecting channel 103 is lower than the height of the left atrium wall fixing structure 102, the left atrium wall fixing structure 102 and the right atrium wall fixing structure 104 are respectively against the left atrium wall and the right atrium wall, and the shunt decompressi...

Embodiment 2

[0048] This embodiment provides an atrial shunt decompression device, which differs from Embodiment 1 in that:

[0049] Such as Figure 8 As shown, the overall shape of the left atrium wall fixing structure 102, the right atrium wall fixing structure 104, and the middle connecting channel 103 in this embodiment is a two-way trumpet shape. The flow is slow and clogged.

[0050] For other specific structures, refer to Embodiment 1.

Embodiment 3

[0052] This embodiment provides an atrial shunt decompression device, which differs from Embodiment 1 in that:

[0053] Such as Figure 9 As shown, in this embodiment, a recovery compression wire harness 109 is added to the right atrium wall fixing structure 104, fixed at the position of the wire harness collector 101, for compressing the left atrium wall fixing structure, and it is convenient to take out the shunt decompression device through the conveyor later.

[0054] For other specific structures, refer to Embodiment 1.

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a device for shunting and decompressing an atrium. The shunting and decompressing device is connected with a conveyor, and comprises a wire harness collector, a left atrium wall fixing structure, a middle connecting channel and a right atrium wall fixing structure, wherein the left atrium wall fixing structure communicates with the right atrium wall fixing structure through the middle connecting channel; one end of the wire harness collector is connected with the left atrium wall fixing structure,and the other end of the wire harness collector is connected with the conveyor; and the left atrium wall fixing structure and the right atrium wall fixing structure are pressed against the two sides of an atrium wall respectively, and are connected with the atrium through the middle connecting channel to shunt and decompress the atrium. By adopting the device, the pressure of the atrium can be lowered, the service life of the atrium is prolonged, heart failure is relieved, and the surgical success rate and surgical operation convenience are increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an atrial shunt decompression device. 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, the main clinical manifest...
