Embodiment Construction

[0036] During the PPH operation (stapled hemorrhoidectomy), the anus needs to be opened first, and then the anus is supported. When the lesion is removed, the lesion needs to be located and the tissue that needs to be protected is not removed. The invention provides an anal expander, which can realize the above functions at the same time, thereby simplifying operation and reducing operation difficulty. The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] Please refer to figure 1 , figure 1 Schematic diagram of...

Abstract

The invention relates to the technical field of medical equipment, and discloses an anal dilatation device. The anal dilatation device comprises a body and a handle, wherein the body has a cylindrical structure; an opening is formed in the tail end of the body; a conical structure of a pre-dilatation surface is arranged on the top of the body; a positioning opening for positioning a surgery part is formed in a side wall of the body; and the handle is provided with a structure which can be fixed with a human body, is movably assembled on the body and limits the body. The anal dilatation device has functions of dilating the anal of a patient in advance, supporting the anal, positioning the surgery part, protecting good tissues and preventing the body from being falling in the anal. During PPH (produce of prolapse and hemorrhoids) surgery, all the functions of the anal dilation device can be fulfilled; the number of instruments operated by surgeons is small; surgical operation is simplified; and surgery difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anal dilator. Background technique [0002] PPH surgery (stapled hemorrhoidectomy) is popular among doctors and patients for its painless postoperative, simple operation and few complications. [0003] At present, in the process of PPH operation, various auxiliary devices such as anal expander sleeve, anal expander, anoscope, and guard plate are needed; among them, the anal expander sleeve is used to pre-stretch the anus, avoiding the direct use of anal expander The anus muscle is strained by using the anal device; the anal expander is used to open the anus to make the operation go smoothly; the anoscope can give the doctor an accurate positioning when the purse is used; the guard is used to protect the good tissue from being removed. [0004] When doing PPH surgery, you need to use the dilator sleeve to open the anus first, then take out the dilator sleeve and pl...
