A new adjustable anal dilator for gastrointestinal surgery

Abstract

The invention discloses a novel adjustable anal dilator for gastrointestinal surgery, which comprises a jacking head, a barrel body and a positioning ring, the barrel body is arranged at the rear end of the jacking head, and the barrel body is far away from the jacking head. The outer side of one end of the head is provided with the positioning ring, the pushing head is composed of a plurality of pushing bending plates, the cylinder body is composed of a plurality of expansion bending plates, and the positioning ring has a plurality of positioning rings. Composed of veneers, the anal expansion curved plate is provided with a contraction sliding cavity inside, the two sides of the anal expansion curved plate are provided with curved plate chutes, and the adjacent expansion anal curved plate is provided with a reaming curved plate , the clips on both sides of the reaming bent plate, and the clips on both sides are respectively clipped into the contraction sliding cavity inside the adjacent said anal reaming curved plate. A novel adjustable anal dilator for gastrointestinal surgery provided by the present invention can gradually expand the patient's anus through the design of the contraction chute and the anal expansion insert to avoid the occurrence of anal fissures.

Description

technical field [0001] The invention relates to the field of gastrointestinal surgery, in particular to a novel adjustable anal dilator for gastrointestinal surgery. Background technique [0002] Anal dilation, also called anal canal dilation, refers to a method of dilating the anus with fingers or instruments under local anesthesia or general anesthesia. Anal expansion is often used in anorectal disease inspection, treatment and postoperative recovery. The existing anal expansion technology requires the use of anal expander to achieve; [0003] An anal dilator with application number CN104706313B includes a chassis, a guide rail disc, an expansion rod, and a connecting ring. The guide rail disc, the expansion rod, and the connecting ring are arranged on one side of the chassis, and the guide rail disc is fixed on the chassis through the expansion rod and the connecting ring. , the chassis is circular, with a ring of protrusions on the outer edge of the chassis, a fixed han...

AI Technical Summary

Problems solved by technology

[0004] The application number is CN102029013A, an anal expander seat for surgery, which is used for the expansion of the anus and the anal canal. : The main body and the wide side of the anal dilator seat for the operation are roll-shaped structures, including a positioning edge and an adjusting edge that can selectively move or fix each other, and the outer wall of the adjusting edge is close to the positioning edge The inner wall of the positioning edge, and the adjustment edge can slide relatively along the inner wall of the positioning edge. Although this invention realizes the function of gradual expansion, it also solves the above-mentioned problem of small contact area, but it adopts the design of the roll-type structure and buckle , there is no guarantee that the buckle will fail during use, and the reel will rebound in the anus, causing secondary injuries, and the adjustment space is also very limited
