Suturing-free anastomosis device for digestive tract

Abstract

The invention discloses a suturing-free anastomosis device for a digestive tract. The suturing-free anastomosis device comprises a pair of matched circular rings, namely a first circular ring and a second circular ring, wherein more than two semispherical first and second magnets are respectively embedded into ring planes of the circular rings; the inner diameter of the first circular ring is greater than that of the second circular ring; the first circular ring and the second circular ring are respectively arranged at two broken ends of the digestive tract; tail end tissues at the broken ends are inwards turned; magnetic poles on the bottom surfaces of the first magnets and the second magnets are opposite; the first magnets and the second magnets attract to each other, so that the first circular ring and the second circular ring attract to each other to clamp the tail end tissues to be perfectly matched; when the first circular ring and the second circular ring attract to each other, every two of the first magnets and the second magnets attract to each other to form a ball; under the attraction force among the magnets, suturing-free anastomosis between the broken ends of the digestive tract is finished; after the anastomosis is finished, the tail ends of the inwards turned tissues are sunken towards one side of the second circular ring; meanwhile, the circular rings are gradually disintegrated in the digestive tract, and the attracted magnets attract to each other to form the balls; the balls and disintegrated degradable material fragments are together discharged out of a body under peristalsis of the digestive tract. The suturing-free anastomosis device is easy to operate and reliable in effect.

Description

technical field [0001] The invention belongs to a medical anastomosis device, in particular to a sutureless alimentary canal anastomosis device. Background technique [0002] The medical anastomosis device is used for the sutureless anastomosis between the digestive tracts of the human body, such as the anastomosis between the two ends of the small intestine after small bowel surgery. [0003] The anastomosis and reconstruction of human hollow organs or blood vessels are important operations in surgical operations. In the past, sutures were used to suture manually, which can achieve satisfactory results, but the operation is time-consuming, and the anastomosis effect depends on the suturing skills and experience of the surgeon. Suture-related complications are also inevitable. For hundreds of years, surgeons have been exploring degradable or non-degradable anastomotic devices or methods without sutures to reduce the difficulty of surgery, simplify surgical steps, and reduce...
