The invention discloses a tricuspid valve repair device. The tricuspid valve repairing device comprises a guiding catheter, a first adjusting mechanism, a conveying catheter, a second adjusting mechanism, a pushing rod and a repairing clamp, the first adjusting mechanism is used for adjusting the bending angle of the far end of the guiding catheter in the first direction and the second direction which are perpendicular to each other, and the conveying catheter is movably arranged in the guiding catheter; the second adjusting mechanism is used for adjusting the bending angle of the conveying catheter relative to the guiding catheter, the pushing rod is movably arranged in the conveying catheter, and the repairing clamp is detachably arranged at the far end of the pushing rod. The movable space range of the repair clamp is enlarged, the repair treatment range of the repair clamp on the tricuspid valve is enlarged, the operation difficulty of a conveying system is reduced to a great extent, and the dependence of a tricuspid valve operation on the technical level and clinical experience of a doctor is weakened.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a tricuspid valve repair device. Background technique [0002] With the development of social economy and the aging of population, the incidence of valvular heart disease has increased significantly. The tricuspid valve is located in the opening between the right atrium and right ventricle. The tricuspid valve opens to allow blood from the right atrium to fill the right ventricle. When the right ventricle contracts to pump blood into the lungs, the tricuspid valve closes to prevent blood flow back to the right atrium. When the tricuspid valve does not close completely, some blood leaks through the tricuspid valve back into the right atrium each time the right ventricle contracts, known as tricuspid regurgitation. The existing valve interventional therapy technology is based on the principle of edge-to-edge surgery to deliver the valve clip to the target tricuspid valve, and simul...
