Gradual chaned and series type intestine dilatation means

Abstract

The pregressive intestinal canal dilator includes four portions of head end, supporting portion, tail end and operation bar. Said dilator possesses the pregressive increment of dilatation, accurate dilatation, is easy to be operated and controlled, can alleviate patient's suffering, has no need of anesthetization, and does not produce complicating diseases of laceration of intestinal wal, bleeding and intestinal fistula.

Description

technical field [0001] The invention relates to an intestinal dilator, in particular to a progressive serial intestinal dilator suitable for treating postoperative rectum and sigmoid colon anastomotic benign strictures. Background technique [0002] The incidence of colorectal cancer is gradually increasing. In my country, about 70% of colorectal cancers occur in the rectum, and there is a certain incidence of colorectal anastomotic stenosis after operation. rise. In the past, there were balloon dilators, because the balloon was compressed to form a gourd shape at the stenotic opening, which could not fully play an expansion role, and the degree of expansion of the stenotic opening could not be understood and precisely controlled; the water (air) bag dilator with a set diameter , since the stenosis is directly expanded to the set width, it will inevitably lead to unbearable pain for the patient, and anesthesia is required, and it is easy to cause complications such as intest...
