Abstract

The invention discloses an anus dilator, which comprises a cylindrical body, a conical guide part and an externally dilated wide edge, wherein the guide part is connected with the far end of the body, and the wide edge is connected with the near end of the body; and the anus dilator also comprises a cylindrical air bag matched wit the body, wherein the air bag is sleeved on the outer surface of the body, and the air bag is communicated with a fluid source through a catheter. Through the anus dilator seat, the anus and the anal canal of a patient can be gradually and controllably enlarged, and the sphincter of the anus can adapt to the amplitude spread by an anus dilator seat before the anus dilator seat is inserted so as to avoid anal fissure and relieve the pain of the patient. The anus dilator can be widely applied to surgical operations.

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 currently commonly used surgical instrument for stretching the anus is the anal expander seat, which includes a cylindrical body and a shoulder for applying force at the tail of the body. The rigid cylindrical body can stretch the anus, and the hollow space in the cylinder Part of it constitutes the channel for other surgical instruments to enter the patient's body. When in use, slowly insert the body of the anal expander seat into the anus from its front end until the anal canal. Although it is generally matched with the inner catheter of the anal expander to enter the anus, the distal end of the anal e...
