Repair device for tricuspid regurgitation surgery

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.
