Problems solved by technology

[0004] In order to overcome the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a magnetic device for side-to-side anastomosis of intestines, which uses the magnetic attraction force of two magnetic rings with suitable thickness and shape to complete the side-to-side anastomosis of intestines without suturing It not only avoids the defects that the tissues around the anastomosis are easy to split, the tissues around the anastomosis are easy to bleed, the anastomosis is obstructed, and the suture is incomplete, which is caused by the gastrointestinal stapler in the intestinal side-to-side anastomosis. The auxiliary magnetic ring can be excreted with feces after a certain period of time, and will not stay in the human body to cause inconvenience and discomfort

Embodiment Construction

[0016] The present invention will be described in more detail below in conjunction with the accompanying drawings.

[0017] The magnetic device for intestinal side-to-side anastomosis includes a magnetic ring set, and the magnetic ring set is composed of two ring-shaped magnetic rings with a thickness between 2 mm and 4 mm, such as figure 1 As shown, each magnetic ring is composed of a first magnetic ring 1 and a second magnetic ring 2, the inner diameter of the first magnetic ring 1 is larger than the outer diameter of the second magnetic ring 2, the thickness of the first magnetic ring 1 is the same as that of the second magnetic ring 2 have the same thickness, the width of the second magnetic ring 2 is one-third of the first magnetic ring 1, and the outer diameter of the first magnetic ring 1 in each pair of magnetic rings is smaller than the inner diameter of the corresponding intestinal tube; in addition, the first magnetic ring The ring 1 and the second magnetic ring 2 a...

Abstract

The invention discloses a magnetic device for side-to-side intestinal anastomosis. The magnetic device comprises a magnetic ring set, wherein the magnetic ring set consists of two pairs of annular magnetic rings with thickness ranging from 2 to 4mm; and each pair of magnetic rings consists of a first magnetic ring and a second magnetic ring. By performing the side-to-side intestinal anastomosis of seamless seaming by using the magnetic attraction of the two pairs of magnetic rings with both proper thickness and shape, the device prevents the defects of easy dehiscence and easy bleeding of perienchyma of the anastomotic stoma produced by a gastrointestinal stapler in the side-to-side intestinal anastomosis, obstruction of the anastomotic stoma and incomplete seaming; and because the two pairs of magnetic rings used in the side-to-side intestinal anastomosis can be removed from the body along with excrement after a certain period, the magnetic rings cannot be remained in human body to cause inconvenience and discomfort.

Description

technical field [0001] The invention relates to a medical device, in particular to a magnetic device for intestinal side-to-side anastomosis. Background technique [0002] Gastrointestinal stapler, as a suturing device for intestinal side-to-side anastomosis, brings great convenience to the operation, but there are also problems that the surrounding tissues of the anastomosis are easy to split, the tissues around the anastomosis are easy to bleed, the anastomosis is obstructed, and the suture is incomplete. Defects. Therefore, using the natural anastomosis effect of the magnetic device to realize intestinal side-to-side anastomosis under wireless suture has become more and more the main direction. [0003] The magnetic device currently used is mainly a magnetic tube device, which can realize side-to-side anastomosis under wireless suture, but the disadvantage is that the magnetic tube and its accessory metal gears remain in the human body, causing great inconvenience and di...
