Embodiment approach

[0030]As an embodiment of the present invention, the drive mechanism for moving up and down is: the lower part of the drive shaft 117 is threadedly connected with the threaded hole of the threaded drive handle 113 through the thread 111, and the bottom of the threaded drive handle 113 is fixed with Knob 114 , the upper end of the threaded driving handle 113 is arranged in the middle hole at the lower end of the handle 105 and the two are in clearance fit, so that the threaded driving handle 113 can rotate relative to the handle 105 axially. Preferably, the upper end of the threaded drive handle 113 is provided with an annular slot 113A, the third fixed pin 112 is screwed into the annular slot of the threaded drive handle 113 from the threaded hole 115 at the lower end of the handle 105 and the third fixed pin shaft 112 can Slide in the threaded driving handle slot 113A, so as to prevent the threaded driving handle 113 from coming out from the lower end of the handle 105 .

Abstract

The invention discloses a manual type anorectal surgery magnetic ring anastomat which comprises an upper magnetic ring shell, an upper magnetic ring is embedded and fixed in a cavity of the upper magnetic ring shell, and a plurality of upper magnetic ring shell clamping grooves are formed in the ring wall of an inner hole of the upper magnetic ring shell. Each upper magnetic ring shell clamping groove can be connected with a correspondingly-arranged claw clamp in a clamped mode, and the claw clamps are commonly fixed to a clamping claw through claw petals. A notch is formed in the side wall of the lower end of the clamping claw, and a lower magnetic ring shell is oppositely arranged below the upper magnetic ring shell. A lower magnetic ring capable of being attracted to the upper magnetic ring is embedded and fixed in a cavity of the lower magnetic ring shell, and the lower magnetic ring shell is embedded in a groove in the upper end of a handle through transition fit. A push rod is arranged in the handle, an annular cutter is arranged at the upper end of the push rod, a driving shaft penetrates through a middle hole of the push rod, the top end of the driving shaft is fixedly connected with the bottom end of the clamping claw, the lower portion of the driving shaft is connected with a vertical driving mechanism, and the lower end of the push rod is connected with the handle. The manual type anorectal surgery magnetic ring anastomat is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a manual 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, v...
