Embodiment Construction

[0028] The postoperative anastomotic dilator for rectal surgery of the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] In describing the present invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", " The orientation or positional relationship indicated by "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, so as to Specific orientation configurations and operations, therefore, are not to be construed as limitations on the invention.

[0030] see Figure 1-3As shown, the postoperative anastomotic stoma dilator for rectal surgery in this embodiment has the function of usin...

Abstract

The invention relates to the technical field of medical instruments, in particular to a postoperative anastomotic stoma dilator for a rectal operation. The postoperative anastomotic stoma dilator comprises an injection mechanism, wherein the front end of the injection mechanism is connected with a tip, a sleeve body is arranged on the outer side of the injection mechanism, the sleeve body and the injection mechanism are connected through a connecting mechanism, a plurality of strip-shaped air bags are arranged outside the sleeve body, an annular air bag is arranged at the rear end of the tip, pressure sensors are arranged on the outer side of the strip-shaped air bag and the outer side of the annular air bag, and the pressure sensors are electrically connected with a displayer. Through cooperative use of protruding strips and the strip-shaped air bags, one section of the rectum of a patient can be supported, and the situation that the rectum is injured due to the fact that the surfaces of the strip-shaped air bags are not smooth is avoided; the annular air bag fixes the other section of the rectum, and protrusions on the surface of the annular air bag can enable the rectum to be attached to the surface of the annular air bag, so the dilator is not prone to falling off in the moving process of the tip; and after a resetting mechanism is used, the strip-shaped air bags and the annular air bag can restore to original positions, and the rectum of the patient is prevented from being scratched in the moving-out process of the dilator.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a postoperative anastomotic dilator for rectal surgery. Background technique [0002] my country is a country with a high incidence of colorectal cancer, and the proportion of patients with low rectal cancer is increasing year by year. With the advancement of technology, many of these patients who were previously unable to preserve the anus have adopted low anastomosis. The rectum is about 12 to 15 centimeters. It can be divided into high rectal cancer, middle rectal cancer and low rectal cancer. Generally, lesions below 5-7 cm from the anal verge are considered low rectal cancers. Anastomosis of the two rectums. Low-position anastomosis often leads to anastomotic stenosis due to weak intestinal blood supply, local inflammation, and the use of the anus due to the need for a protective stoma three months after the operation. [0003] At present, there is no special exp...
