Embodiment

[0028] A combined magnetic intestinal stapler, the combined magnetic intestinal stapler is realized by the cooperation of two magnetic rings, a female ring and a female ring, wherein the female ring has a raised part; The internal filling material and several magnets are composed of three parts; the magnets are evenly arranged in the annular space of the shell; the internal filling material fills and compacts the space inside the shell except the magnets; after filling, the shell is sealed with a back cover by welding or biological glue.

[0029] The two magnetic rings of the stapler, the female and the female, are a combined structure. The female and the female magnetic rings are different in shape. They are composed of three parts: the shell (including the back cover), the internal filling material and the magnet (2-8 pieces). The magnet provides The magnetic force makes the mother and child magnetic rings attract each other to squeeze the intestinal tissue through magnetic f...

Abstract

The invention provides a combined type magnetic anastomat. The magnetic anastomat comprises two magnetic rings, wherein each magnetic ring comprises an annular shell main body; an inner filling material and a plurality of magnets which are arranged uniformly are arranged in each annular shell main body; the inside of each annular shell main body is filled with the inner filling material except for space with the magnets; each annular shell main body is provided with an annular cover plate of which the shape corresponds to that of the annular shell main body; the annular shell main bodies and the annular cover plates are made of degradable materials; and the inner filling materials are degradable materials or dissoluble materials. In the preliminary stage of anastomosis, magnetic-pressure anastomosis on the magnetic rings can be carried out by magnetic force provided by the magnets; and in the later stage of the anastomosis, the sizes of the magnetic rings are reduced along with degradation or dissolution of the annular shell main bodies, the annular cover plates, the inner filling materials and the like in the magnetic rings, and the magnetic anastomat can be discharged out of a human body smoothly.

Description

technical field [0001] The invention relates to a combined magnetic stapler. Background technique [0002] The anastomotic reconstruction technique of surgical hollow viscera is a basic operation in the process of operation, and affects the operation process and postoperative effect. In recent years, with the continuous development of surgical technology, surgical anastomosis methods have also been developed. Magnetic compression anastomosis uses magnets to attract each other to compress the tissue and the magnetic field assists to form an anastomosis between hollow organs. The advantages of less related complications. However, from the point of view of clinical practice, when performing intestinal anastomosis, due to the large volume of the magnetic stapler, it is not easy to be excreted after the anastomosis, and often needs to be removed by surgery, which brings great inconvenience to the postoperative life of the patient and affects the magnetic anastomosis. practical...
