Anal dilatation device

Abstract

The invention discloses an anal dilatation device. The anal dilatation device comprises a main body and a sealing sleeve installation seat, wherein the main body is of a cylindrical structure; the main body comprises a dilatation part and an adjusting part; the dilatation part is provided with a plurality of support strips which are expanded in a radial way, and a flexible adjusting sleeve which is sheathed at the exterior of each support strip; the adjusting part comprises an inner cylinder and an outer cylinder; the multiple support strips are connected with one side, near the inserting end,of the inner cylinder along the circumference; the outer cylinder is connected with the inner cylinder by threads; the outer cylinder is used for drawing the multiple support strips in; the flexibleconnecting sleeve is used for coating the support strips; the sealing sleeve installation seat is fixedly connected with the inner cylinder; the sealing sleeve installation seat comprises a cylindrical installation ring and a bundling ring, and the bundling ring is sheathed with an installation ring; the bundling ring is used for bundling the sealing sleeve sheathed on the installation ring; the bundling ring is provided with an adjusting assembly, and is used for adjusting the inner diameter of the bundling ring to provide a channel suitable for TAMIS (transanal minimally invasive surgery). The anal dilatation device has the advantages that the structure is simple; the anal dilatation device can be conveniently positioned at the anus; an installation seat for the installation of gloves orother sealing sleeves is provided, so that the slipping is prevented.

Description

technical field [0001] The invention relates to the field of medical instruments, and more specifically relates to an anal dilator. Background technique [0002] With the development of endoscopic and laparoscopic techniques, minimally invasive surgery for the treatment of early rectal tumors has become a trend. The concept of natural orifice endoscopic surgery provides a new direction for the development of minimally invasive surgery, and TEM is its representative. Because of its advantages such as rapid postoperative recovery, this technique has been recommended by NCCN as the first choice for local excision for the treatment of early rectal tumors. However, TEM requires special equipment and instruments, which are expensive, and the operation needs to pass through a long and hard surgical channel, which makes it difficult to angle the instruments, and the operation is more complicated. Operators need a long learning curve, which limits the clinical application of TEM. ...

Problems solved by technology

In previous research reports, TAMIS surgery mostly uses commercial surgical channels, such as single-hole laparoscopic access, but due to the strong contractility of the anal sphincter, the existing single-hole laparoscopic access cannot adapt to the anus as the entrance In addition, the existing single-hole laparoscopic access is closed by combining gloves. When using laparoscopic instruments, the range of motion of the instruments is wider, but it is often simply to pass the gloves through the rubber band during use. Or other rope-like structure restraint, easy to slip off during the operation
