The invention discloses a sutureless technology between a protogenetic blood vessel and an artificial blood vessel. The sutureless technology involves a supporting base, the front end and the rear endof the supporting base are fixedly provided with supporting plates respectively, the upper end face of the supporting base is provided with a supporting block, and the upper side of the supporting block is a connecting tube capable of being connected with the protogenetic blood vessel and the artificial blood vessel. A flow pipeline penetrating through the connecting tube is arranged in the connecting tube, annular grooves communicated with the outside space are formed in the left end and the right end of the connecting tube, a driving mechanism used for driving a device to run is arranged inthe supporting base, the upper side of the driving mechanism is provided with two tension mechanisms, and two transmission mechanisms capable of making an elastic ring membrane separated from tensionrods are arranged in the supporting plates. The device is simple in structure and convenient to operate; by means of the device, sutureless connection between the protogenetic blood vessel and the artificial blood vessel can be automatically completed, manual operation is not needed, while the working efficiency is improved, errors caused by manual operation are reduced, and the connection success rate is increased.
Description
technical field [0001] The invention relates to the field of blood vessel connection, in particular to a suture-free technology between native blood vessels and artificial blood vessels. Background technique [0002] The incidence of cardiovascular diseases in people is getting higher and higher. When performing cardiovascular surgery, usually when performing operations on blood vessels, it is necessary to cut off blood vessels and connect artificial blood vessel drainage to ensure normal blood vessel circulation; [0003] At this stage, when connecting native blood vessels and artificial blood vessels, most doctors connect them by suturing, which is time-consuming and labor-intensive, which increases the operation time and increases the risk of the operation, which is not conducive to the rapid and efficient operation. . Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a suture-free technology between native blo...
