Description

Anorectal lamp for indicating distal resection margin of rectal cancer

Technical Field

The utility model relates to the technical field of medical instruments, in particular to an anorectal lamp for indicating the distal resection margin of rectal cancer.

Background Art

Good control of the distal resection margin in laparoscopic radical resection of rectal cancer can improve the patient's anal preservation rate and play a vital role in the success of the operation. Currently, there are three common ways to locate the distal resection margin. The first is to use intraoperative instruments for direct positioning. The distal resection margin is determined according to the location of the tumor during surgery. This method cannot determine the distance between the lower edge of the tumor and the distal resection margin, and it cannot locate smaller tumors. The second is intraoperative transanal digital diagnosis positioning. This method cannot determine the distance between the lower edge of the tumor and the distal resection margin, and it cannot locate higher tumors. The third method uses preoperative colonoscopy to inject methylene blue to mark the distal part of the tumor. This method is complicated to operate. The injection of methylene blue for low-position rectal cancer affects the anatomical level and greatly affects the operation. It has been abandoned.

In the prior art, there is no suitable instrument to check the inside of the rectum in laparoscopic rectal cancer surgery, and the doctor relies on the fingers to check and sense it, which leads to inaccurate judgment of the location of the rectal cancer. Therefore, in order to solve the above problem, we propose a new type of anorectal light to indicate the distal resection margin of rectal cancer.

Utility Model Content

The utility model aims to solve the problem in the prior art that there is no suitable instrument to check the inside of the rectum during laparoscopic rectal cancer surgery, especially the inability to accurately locate the lower cutting edge of the tumor, and the doctor relies on the fingers to check and sense it by himself, resulting in inaccurate judgment of the position of the rectal cancer during the operation. An anorectal lamp for indicating the distal cutting edge of rectal cancer is proposed.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anorectal lamp indicating the distal resection edge of rectal cancer, comprising a shell, a first switch is arranged on the top of the shell, a telescopic tube is slidably arranged between the inner surface walls of the shell, a display is arranged on the outer surface of the shell near the top, a push rod is slidably penetrated through the top of the shell, the bottom end of the push rod is fixedly connected to the top of the telescopic tube, a line groove is symmetrically opened near the edge of the top of the telescopic tube, a wire is arranged inside the line groove, and a built-in light and a camera are arranged at the bottom of the telescopic tube.

Furthermore, the display, the built-in light, the camera, the wire and the first switch cooperate with each other, and a rubber sleeve is provided on the outer surface of the push rod near the top.

Furthermore, an anti-slip sleeve is fixedly connected to the outer surface of the shell, and limiting grooves are symmetrically provided on the inner surface wall of the shell.

Furthermore, a limiting block is symmetrically fixedly connected to the outer surface of the telescopic tube near the top, and the outer surface of the limiting block is in contact with the inner surface wall of the limiting groove.

Furthermore, a second hollow sleeve is fixedly connected between the inner surface walls of the line groove near the bottom, and a first hollow sleeve is slidably provided on the outer surface of the second hollow sleeve.

Furthermore, the top of the first hollow sleeve is fixedly connected to the inner top of the outer shell, and the wire is located between the inner surface walls of the second hollow sleeve.

Furthermore, a protective cover is fixedly connected to the bottom of the telescopic tube, and the protective cover is arranged in a semicircular shape.

Compared with the prior art, the advantages and positive effects of the utility model are:

1. In the utility model, the device is lubricated and inserted into the rectum from the patient's anus, and then the built-in light, camera and display cooperate to facilitate medical personnel to view the situation in the patient's rectum. In addition, with the push rod, the situation deeper in the rectum can be observed, so that the location of rectal cancer can be accurately found, the lower edge of the tumor can be accurately located, and the position of the distal resection edge of the rectal cancer can be indicated, which is convenient for surgical removal of the tumor.

2. In the utility model, when the telescopic tube slides inside the shell, the first hollow sleeve and the second hollow sleeve slide synchronously, which can effectively prevent the wire from being squeezed and entangled between the telescopic tube and the shell when the telescopic tube retracts. By setting a semicircular protective cover, it can provide protection for the built-in light and camera without affecting their operation, and can effectively prevent the telescopic tube from easily scratching the inner wall of the rectum when entering the rectum, thereby improving safety.
