Problems solved by technology

However, this method uses specific tubes to connect long needles in European and American countries, while soft long needles are used in China. These methods will not only increase the infection rate of treatment, but also cannot solve the problem of hemorrhoid fixation and positioning.
[0005] Due to different purposes, there is currently no anoscope specifically for sclerotherapy injections on the market

Embodiment

[0058] Make a kind of internal hemorrhoid injection anoscope according to the following dimensions, the length of the cylindrical mirror body is about 6cm. The outer diameter of the cylindrical mirror body is 3cm, and the depression is a spherical surface with a depth of 1.5cm. The curvature of the spherical surface is 0.3, and the height of the spherical surface is 0.5cm. The injection port is circular and its area is 1 / 3 of the bottom area. The injection channel is trumpet-shaped, and the relatively small end of the trumpet-shaped is the injection port. A handle is provided on the bottom surface, and a rubber non-slip device is provided on the handle.

[0059] For specific treatment, the patient is placed in the right lateral position, first determine the number of hemorrhoids that need to be injected, and after local disinfection, push the anoscope for internal hemorrhoid injection dipped in paraffin oil into the anus, and push the mirror to the bottom. The size of about ...

Abstract

The invention relates to the field of medical devices and in particular to an injection anoscope for internal hemorrhoid. The injection anoscope for internal hemorrhoid, which is provided by the invention, comprises a columnar mirror, a guide part and more than one handle, wherein the guide part is positioned at the top of the columnar mirror, the handle is connected with the bottom of the columnar mirror, a recess is formed on the side wall of the columnar mirror, a columnar injection channel is formed inside the columnar mirror, one end of the injection channel is opened to form a tissue view window which is positioned on the recess, and the other end of the injection channel is opened to form an injection port which is positioned at the bottom of the columnar mirror. The anoscope provided by the invention enables an operator to control the needle insertion depth and inject an appropriate amount of injection solution in a directly visual manner, greatly reduces the difficulty of injection, prevents a series of complications caused by injection to the rectal muscular layer or surface injection, and reduces the operation difficulty to the greatest extent.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an internal hemorrhoid injection anoscope. Background technique [0002] Internal hemorrhoid sclerosing agent injection treatment is one of the three methods of treating hemorrhoids at home and abroad. It is widely used in the treatment of stage I-II bleeding internal hemorrhoids and has a history of hundreds of years. The treatment is done without anesthesia by injecting a sclerosant in a syringe into the specific hemorrhoid with the aid of an anoscope. [0003] Anoscopes commonly used in clinical practice are mainly divided into inspection and auxiliary surgery. The former is divided into straight and oblique, while the latter has expansion function. Both are cylindrical structures with a length between 7-9cm. When inspecting and assisting surgery, these two anoscopes can observe and expose the entire end of the rectum, find local lesions, and fully expose the parts that ne...
