A repair device for tricuspid regurgitation surgery

Abstract

The invention discloses a repair device for a tricuspid regurgitation surgery. The device comprises a hollow sheath tube and a valve measuring assembly and a valve bracket assembly respectively matched with the hollow sheath tube, the valve measuring assembly comprises a microcontroller, an inflating balloon, an inflating and deflating air tube, an air pump and a drainage tube, the inflating balloon is of a ring structure, the inflating balloon surrounds the outer circumference of the inflating and deflating air tube and the drainage tube, the inflating and deflating air tube is provided witha gas release valve, a micro controller is connected with a button module, an ultrasonic wave flow sensor and a voltage acquisition module, and a valve stent assembly includes a valve stent, a biological valve, a push rod, an anchor, a first pull wire and a second pull wire. The device has the advantages of simple structure and reasonable design, the working voltage of the air pump corresponds tothe expansion size of the inflatable balloon, the digital control of the valve size measurement is achieved, the automation degree is high, the anchor is arranged on the biological valve, thereby solving the problem that the in-situ fixation of the biological valve is difficult, and the use effect is good.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a repair device for tricuspid regurgitation surgery. Background technique [0002] The most common type of tricuspid valve disease is tricuspid regurgitation, with a high incidence rate, second only to left heart valve disease. It is generally believed that tricuspid regurgitation can be significantly relieved after other valve operations, so tricuspid valve-related lesions have been neglected for a long time. There is a large amount of evidence showing that moderate to severe tricuspid regurgitation needs to be treated again after tricuspid valve repair or replacement surgery, prompting the increase of indications for tricuspid valve intervention; however, in most cases, the risk of secondary surgery and The case fatality rate is high. [0003] With the rapid development and application of transcatheter treatment of aortic valve and mitral valve diseases, m...

Problems solved by technology

[0004] At present, there are two main problems in the transcatheter tricuspid valve interventional treatment: one is that due to severe tricuspid regurgitation, the tricuspid annulus has been severely deformed, and the tricuspid valve is calcified. The implanted valve stent is difficult to fix in situ, so the regurgitation of the interventional valve is often unacceptable due to the change of position; the other is that although the size of the patient's heart valve annulus is measured before the operation by cardiac color Doppler ultrasound, due to color Doppler ultrasound examination It is a means of medical imaging examination. The size of the patient's heart valve ring cannot be accurately measured. It can only be used as a clinical reference. The actual measurement of the size of the heart valve ring during the operation will be used as the basis for directly replacing the size of the artificial heart valve.

If the selected artificial heart valve does not match the size of the valve ring of the patient, it will directly affect the postoperative quality of life of the patient, and seriously endanger the life of the patient.
