Embodiment 1

[0050] Using the device shown in Figure 2(A) to prepare a magnetic ring artificial sphincter, 1 is a ferromagnetic metal body made of iron-nickel-cobalt, 2 is a support made of titanium alloy, and 4 is made of pure titanium retractable cable. 20 combined magnetic bodies with permanent magnetism and a diameter of 6 mm are connected in series through a slidable and stretchable titanium wire to prepare a magnetic ring artificial sphincter, and then determine the number of magnetic bodies according to the size of the esophageal lumen. The site where the magnetic ring artificial sphincter needs to be implanted is dissociated, and a properly sterilized magnetic artificial sphincter is implanted, and the two ends are connected to form a ring, and finally the infection is controlled.

Embodiment 2

[0052] Using the device shown in Figure 2(A) to prepare a magnetic ring artificial sphincter, 1 is a permanent magnetic metal body made of AlNiCo, and 2 is a support made of stainless steel alloy covered with a biocompatible material Body, 4 is a stretchable connecting wire made of pure aluminum and covered with biocompatible material. 20 combined magnetic bodies with permanent magnetism and a diameter of 6 mm are connected in series through slidable and stretchable aluminum wires to prepare a magnetic ring artificial sphincter, and then determine the number of magnetic bodies according to the size of the esophageal lumen. The site where the magnetic ring artificial sphincter needs to be implanted is dissociated, and a properly sterilized magnetic artificial sphincter is implanted, and the two ends are connected to form a ring, and finally the infection is controlled.

Embodiment 3

[0054] use as image 3 The device shown, the preparation of magnetic ring artificial sphincter: 20 non-combined spherical magnetic bodies with permanent magnetism and a diameter of 6 mm are connected in series through rubber wires to prepare a magnetic bead-type magnetic ring artificial sphincter, and then according to the pyloric tube Determine the size of the cavity, determine the number of magnetic bodies, dissociate the part that needs to be implanted into the magnetic ring artificial sphincter, implant the appropriate sterilized magnetic body artificial sphincter, connect the two ends to form a ring, and finally carry out infection control.

Abstract

The invention relates to a magnetic-ring artificial sphincter, namely an annular structural device based on magnetic bodies. The magnetic-ring artificial sphincter is formed by connecting a plurality of magnetic bodies in series through connection materials. Expansion and shrinkage with reversibility can be achieved through the magnetic force absorption effect of the magnetic bodies and sliding and flexible characteristics of the connection materials. The magnetic-ring artificial sphincter is embedded around cavity pipelines in the bodies, can simulate functions of a normal human sphincter, can enhance or rebuild the sphincter functions of organs reducing in or losing sphincter force, controls normal flow direction of contents of hollow organs, and can substitute or rebuild sphincter tissues at positions of esophagus, cardia, pylorus, ileocecus, anal canals, bladders, positions around urethral canals, alimentary canals and urinary tract stomas and the like. The magnetic-ring artificial sphincter is convenient in operation, few in manufacture process, reliable in function and wide in application prospect in the field of biomedicine.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic ring artificial sphincter, that is, a ring structure device based on a magnetic body. Magnetic bodies composed of magnetic metals, biocompatible materials and supporting materials are connected in series through connecting materials and embedded in the circumference of hollow organs in the body, which can replace or reconstruct the esophagus, cardia, pylorus, ileocecal, anus, etc. The sphincter structure of the tube, urethra, intestinal tract and urinary stoma, etc., strengthen or rebuild the sphincter ability of organs with weakened or lost sphincter strength, and control the normal flow and excretion of the contents of the digestive tract and urinary tract. Background technique [0002] The sphincter is a circular muscle distributed around some hollow organs in the human body, and plays a vital role in controlling the normal flow of the contents of the hollow organs. Weakness or ...
