Kidney-shaped elastic rectoscope

Abstract

The invention relates to a kidney-shaped elastic rectoscope which is a rectoscope applied to surgery, check, medicine injection and the like of the rectum and the sigmoid flexure. A rectoscope body of a traditional rectoscope is a straight-cylinder-shaped circular tube and made of non-elastic materials, so that when the traditional rectoscope is used, the traditional rectoscope must be fixed by external force and is inconvenient to use. The kidney-shaped elastic rectoscope is made of elastic high-polymer materials. A whole rectoscope body is a kidney-shaped circular tube with the middle portion thin and the two ends thick, the upper portion of the rectoscope body is a long straight-cylinder-shaped circular tube, the middle of the rectoscope body is a thin kidney-shaped circular tube, and the lower portion of the rectoscope body is a short straight-cylinder-shaped tube or a trapezoid circular tube. The rectoscope can be folded and placed in the rectum and after the folded rectoscope is placed in the rectum, the rectoscope can be restored to the kidney-shaped tube through the elasticity and expansion through appropriate external force. The rectum is expanded by the upper portion of the rectoscope, the anus is expanded by the middle portion, and the rectoscope is held and fixed through the anal sphincter, fixation through the external force is not needed, and use is convenient. The kidney-shaped elastic rectoscope is suitable for the processes of endoscopic surgery, taking out of a sample, check, medicine injection and the like conducted for a rectum sigmoid flexure disease or conducted in the anorectum.

Description

technical field [0001] The invention relates to a waist-shaped elastic rectoscope, which is a rectoscope used for rectal and sigmoid colon operation, inspection, drug infusion and the like. Background technique [0002] The mirror body of the traditional rectoscope is a straight cylindrical tube made of inelastic metal, plastic, glass and other materials. The expansion range of the rectum is the same as that of the anus. External force such as hands or instruments must be used for rectal examination. Fixed, not easy to use. [0003] From the beginning of the 2010s, transanorectal "natural cavity endoscopic surgery" or "natural cavity specimen removal" is more minimally invasive than traditional laparoscopic surgery, and will become the main or important part of colorectal and other abdominal visceral resection operations. As a component part, the tools used are represented by the "transanal microsurgery system". The rectoscope body used is still a traditional straight cylin...

[0003] From the beginning of the 2010s, transanorectal "natural cavity endoscopic surgery" or "natural cavity specimen removal" is more minimally invasive than traditional laparoscopic surgery, and will become the main or important part of colorectal and other abdominal viscera resections. As a component part, the tools used are represented by the "transanal microsurgery system". The rectoscope body used is still a traditional straight cylindrical tube, and most of them are made of metal, which needs to be fixed with a bracket, which is very inconvenient. And the price is expensive, which increases the financial burden of patients
