Embodiment Construction

[0018] Such as Figure 1-Figure 3 As shown, the present invention discloses a novel anal dilator, which includes a cylindrical body 2 and an outwardly expanded wide side 1 arranged at the proximal end of the body 2 . The novel anal dilator also includes a hollow anal expansion cap 3, which is arranged on the far end of the body 2; The conical guide portion 32 at the end and the conical connecting portion 32 arranged between the anal expansion portion 31 and the guiding portion 33, the cross-sectional area of ​​the proximal end of the connecting portion 32 is greater than the cross-sectional area of ​​the distal end; The maximum outer diameter of the anal expansion cap 3 is smaller than the outer diameter of the main body 2 . Of course, the connecting portion 32 can also be designed as a cylinder.

[0019] The inner diameter of the expanding anus part 31 gradually increases from its far end to its proximal end, so that it can slowly expand the anus; The connecting part 32 is...

Abstract

The invention discloses an anus dilator for dilating an anus and an anal canal. The anus dilator comprises a cylindrical body and an externally dilated wide edge, wherein the wide edge is formed at the near end of the body, and the far end of the body is provided with a hollow anus dilating cap; the anus dilating cap comprises a circular anus dilating part at the near end, a conical guide part at the far end and a connecting part between the anus dilating part and the guide part; and the maximum outside diameter of the anus dilating cap is smaller than the outside diameter of the body. The anus dilator has main advantages that: the anus and the anal canal of a patient can be gradually and controllably enlarged, and the sphincter of the anus gradually adapts to the amplitude spread by the body of the anus dilator so as to avoid anal fissure and relieve the pain of the patient; and meanwhile, anus pre-dilation and anus dilation are integrally designed so that the novel anus dilator is easier and more convenient to use.

Description

technical field [0001] The invention relates to an anal dilator for surgical operations, belonging to the technical field of medical instruments. Background technique [0002] When performing inspection, diagnosis or surgical treatment in anorectal surgery, it is necessary to stretch the anus first, and then put in other surgical instruments for inspection or treatment. The commonly used surgical instrument for stretching the anus is the anal expander seat, which includes a cylindrical body and a wide side for applying force at the tail of the body. The rigid cylindrical body can stretch the anus, and the hollow part in the cylinder It constitutes the passage for other surgical instruments to enter the patient's body. When in use, slowly insert the body of the anal expander seat from its front end to the anus until the anal canal. Since the diameter of the cylindrical body of the anal expander seat is usually relatively large (generally more than 30 millimeters), the anal e...
