Anus stenosis dilator

Abstract

The utility model relates to an anus stenosis dilator, which effectively solves the problems that the existing anus dilation operation is troublesome, the anus is easy to damage and the effect is not ideal. The anus stenosis dilator comprises a shell, a sleeve is coaxially fixed to the left side in the shell, a guide disc is rotationally connected to the right end of the sleeve, a supporting shaft is coaxially fixed in the shell, the supporting shaft is sleeved with an adjusting disc, two parallel inclined grooves are formed in the adjusting disc, a guide groove is formed in the guide disc, two vertically opposite sliding plates are slidably connected into the guide groove, and the left ends of the sliding plates are detachably connected with an anal dilatation rod; the inner wall of the shell is coaxially and rotationally connected with an annular cylinder, radial grooves are formed in the upper sides and the lower sides of the opposite ends of the guide disc and the adjusting disc correspondingly, connecting blocks are slidably connected into the radial grooves, the sleeve and the supporting shaft are sleeved with shaft sleeves capable of moving left and right correspondingly, connecting rods are hinged to the upper and lower ends of the shaft sleeves, and the free ends of the connecting rods are hinged to the connecting blocks on the corresponding sides; and the anus stenosis dilator can conduct arc massage on the anus and the anal canal, and sphincter is pulled and loosened while dilation is conducted.

Description

technical field [0001] The invention relates to the technical field of anorectal surgery, in particular to an anal stenosis dilator. Background technique [0002] Anal stenosis is a condition in which the diameter of the anus and anal canal becomes smaller, which can lead to difficulty in passing feces, thinner stools, pain in the anus during defecation, and inability to pass the anus smoothly through the index finger during objective examination. [0003] The doctor wears finger cots, applies liquid paraffin, inserts two index fingers into the anus, and repeatedly expands the anus in an arc, loosens the sphincter while expanding, and gradually extends the two middle fingers until the anal sphincter has no sense of urgency. Small, medium and large anoscopes and anal dilators are used to dilate the anus once or twice a week, and then the interval is gradually extended until the stenosis disappears and there is no recurrence. It generally takes 6 to 8 weeks and the curative ef...
