Magnetic loop anastomat for anorectal surgery

Abstract

The invention discloses a magnetic ring anastomat for anorectal surgery; the anastomat comprises a grip which is composed of a left grip and a right grip which are same in structure and are symmetrically arranged, wherein a supporting rod is fixedly arranged at the top of the grip; a push rod cover which can slide in the axial direction of the supporting rod is sleeved on the supporting rod; a lower magnetic ring is embedded and fixed in a groove of a lower magnetic ring shell; the lower magnetic ring shell is arranged at the upper end of the push rod cover; two limiting bosses which are symmetrically formed in the outer ring wall of the lower magnetic ring shell; the two limiting bosses extend into a limiting groove formed in the inner ring wall of the push rod cover; two press sheets are symmetrically arranged on two sides of the bottom of the push rod cover; an upper magnetic ring is embedded and fixed in a groove of an upper magnetic ring shell; the upper magnetic ring shell is relatively arranged above the lower magnetic ring shell; supporting rod clamping sheets are respectively arranged at the tops of various subordinate supporting rods in a mode of extending towards outer side; upper magnetic ring shell clamping grooves corresponding to the various subordinate supporting rod clamping sheets are formed in the inner ring wall of the upper magnetic ring shell; and the various subordinate supporting rod clamping sheets are respectively inserted into the upper magnetic ring shell clamping grooves which are correspondingly arranged. The magnetic ring anastomat is simple in structure and convenient in operation.

Description

technical field [0001] The invention relates to a stapler for anorectal surgery, in particular to a surgical stapler utilizing the performance of a magnetic ring. Background technique [0002] The principle of magnetic ring anastomosis is to use the strong attraction between the magnetic rings made of high magnetic materials to produce a continuous, non-penetrating, magnetic force that gradually strengthens as the distance between the two magnetic rings decreases. The two magnetic rings of the same shape are automatically combined in three-dimensional space to perform precise alignment, resulting in ischemic necrosis of the intestinal wall compressed between the two magnetic rings, and at the same time, the adjacent intestinal wall outside the magnetic ring gradually heals. At present, magnetic compression technology is mainly used in various traditional operations such as postoperative biliary stenosis treatment, coronary artery bypass grafting, stenosis treatment, vascular...
