This utility model discloses a duckbill-shaped intraoperative suction device, comprising a suction head, a suction tube, and a negative pressure suction device connected in sequence. The suction head is a flat tubular structure with a thickness smaller than its length and width. One end of the suction head along its length is directly or indirectly connected to and communicates with the suction tube, while the other end of the suction head along its length is a closed end or has an end through hole. Multiple through suction holes are also distributed on the suction head. This duckbill-shaped intraoperative suction device replaces the traditional cylindrical suction head with a duckbill-shaped, flat tubular structure. The suction head has a thin and flat shape, making it better suited for patients undergoing reoperation, especially children. It can be inserted behind the sternum in a very small space and increases the area of ​​protection behind the sternum, helping to avoid damage to the heart and major blood vessels behind the sternum during a second thoracotomy.

The invention provides a respiratory tract secretion suction and discharge device used after thoracotomy, and belongs to the technical field of medical instruments. The respiratory tract secretion suction and discharge device after thoracotomy comprises a negative pressure suction and discharge device, a negative pressure pipe is fixedly connected to the negative pressure suction and discharge device, a suction and discharge pipe connector is connected to one end of the negative pressure pipe in an inserted mode, and a suction and discharge pipe is fixedly connected to the suction and discharge pipe connector; the backflow prevention unit is used for preventing the sucked respiratory tract secretions from flowing back to the body of the patient and puncturing the secretions with high concentration so as to be sucked out conveniently, and the backflow prevention unit is connected with the suction and discharge pipe. According to the scheme, the respiratory tract secretion suction and discharge device after thoracotomy is provided with the backflow prevention unit and the puncture head, so that the technical problems that secretion sucked out by a negative pressure suction and discharge device can flow back into the respiratory tract of a patient through a suction and discharge pipe, and meanwhile, a common suction and discharge device is poor in suction and discharge effect on high-concentration secretion in the respiratory tract of the patient are solved.

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.
