Elastic loop anus loop ligature instrument

Abstract

The invention discloses an elastic loop anus loop ligature instrument which comprises an inner sleeve, an outer sleeve and at least one group of thread push tube components, wherein the inner sleeve is provided with a vacuum pipe; an inner launching sleeve which communicates with the vacuum pipe to suck lesion tissue is fixedly arranged at the front end of the inner sleeve; at least one containinggroove which is distributed along an axial direction to contain elastic loops is formed in the outer periphery of the inner launching sleeve; the outer periphery of the inner sleeve is sleeved by theouter sleeve; the outer sleeve is propped against a wrench which is rotationally mounted on a shell to move relative to the inner sleeve under the action of the wrench; an outer launching sleeve which is arranged at the outer periphery of the inner launching sleeve in a sleeving manner to push all elastic loops to move forwards in a direction close to lesion tissue till sucked lesion tissue is sleeved by elastic loops in containing grooves close to the lesion tissue is fixedly arranged at the front end of the outer sleeve; and the thread push tube components are detachably and fixedly arranged at the outer circumference of the outer sleeve, are correspondingly connected with the elastic loops sleeved by the containing grooves, and are used for withdrawing corresponding elastic loops to tie and bundle the lesion tissue after the lesion tissue is sleeved by the elastic loops. The elastic loop anus loop ligature instrument is convenient to operate since only the wrench needs to be shifted in an operation.

Description

technical field [0001] The invention relates to anorectal medical equipment, in particular to an elastic thread anorectal ligation device. Background technique [0002] Anorectal ligation is a common surgical operation for treating hemorrhoids with anorectal ligation. It is widely used, and it is particularly necessary to naturally improve anorectal ligation. [0003] The working principle of the anorectal ligation device is to use vacuum negative pressure to suck the hemorrhoid tissue into the gun barrel, and then tie the special rubber ring or elastic coil on the base of the hemorrhoid mucosa, and use the elastic retraction force of the ligation coil to block the hemorrhoid. Blood supply may reduce venous backflow, reduce hyperemia and hypertrophy of hemorrhoids, blood stasis, make it ischemia, atrophy, and ligated tissues gradually fall off, and facilitate wound tissue healing. [0004] Anorectal ligation devices are divided into rubber ring anorectal ligation devices an...

Problems solved by technology

During the whole operation process, due to the frequent and accurate rotation of the winding wheel and the line release wheel, many actions need to be performed continuously and the operation time is long, which is extremely inconvenient to operate
