A method for performing a robotic-assisted orthotopic heart transplant includes forming a working port subareolarly by a mini-thoracotomy at a working intercostal space, forming additional ports for robotic arms, and arranging robotic arms through the ports. A first robotic arm with first forceps extends through a second port lateral to a mid-clavicular line, while second and third robotic arms containing an imaging device and second forceps operate through the working port. A fourth robotic arm with scissors or needle holder extends through a third port proximal to an anterior axillary line. The method includes cannulating for cardiopulmonary bypass, opening the pericardium, cross-clamping the aorta, removing the native heart, and performing sequential anastomoses of the donor heart including the left atrium, pulmonary artery, aorta, inferior vena cava, and superior vena cava.

The application provides a thoracotomy device for thoracic surgery assistance, and belongs to the technical field of medical instruments. The device comprises a guide frame, an expansion plate and two groups of symmetrically distributed supporting rods. A guide groove is formed through the outer surface of the guide frame. A sliding block is slidably connected to the inner side of the guide groove. The outer surface of the sliding block is fixedly connected to the supporting rod. A traction assembly for placing the expansion plate is arranged on the outer side of the supporting rod. An expansion assembly is arranged on the inner side of the guide frame. The expansion assembly comprises a guide block slidably connected to the inner side of the guide frame. In the above scheme, the expansion assembly is arranged. The corresponding positions of the observation scale and the scale line can be used to intuitively measure the rib expansion distance. Therefore, the appropriate expansion distance can be adjusted according to the physical indications of the patient. The damage to the ribs during the thoracotomy and rib expansion process can be effectively reduced, and the operation safety and convenience are further improved.

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.

[Problem] To provide a medical device with which it is possible to treat a stricture formed in a part of the blood vessels of the heart when performing thoracotomy in coronary artery bypass graft surgery, etc. [Solution] A medical device 1 has: a conduit 10, 20 that penetrates the wall of the coronary artery (V) and is inserted into the coronary artery; an expandable expansion part 70 that is provided at the distal end of the conduit; and an expansion means 40 that causes the expansion part to expand. A stricture formed in the coronary artery is expanded by the expansion of the expansion part.

The invention discloses a construction method and application of a dog lung space-occupying lesion model. The invention provides a method for constructing a peripheral lung lesion model on the periphery of a dog lung by injecting a temperature-sensitive hydrogel mixture through a natural orifice by using a bronchoscope, which overcomes the technical problems of strong invasiveness, complex modeling, low success rate, uncontrollable or unstable focus image and the like in the prior art. And the low-invasive, rapid, visible and stable peripheral lung disease canine model is constructed. Compared with existing percutaneous puncture or thoracotomy modeling, the method has the advantages that surgical operation is not needed, the modeling speed is high, imaging is visible, the focus stability is high, the simulation degree of an animal model to human peripheral lung lesion is remarkably improved, and a high-quality experimental platform is provided for related disease mechanism research and new technical verification.
