Abstract

The invention discloses an anus dilator base component, comprising an anus dilator base, wherein the an anus dilator base comprises a body and a wide edge dilating outwards; the wide edge is connected with the near end of the body; and the body comprises a group of anus dilating pieces which are arranged in a surrounding manner. The anus dilator base component also comprises a driving device, wherein the driving device comprises a drive rod and a tapered cap connected with the far end of the drive rod; and the bottom end of the tapered cap is provided with a furling slot. The component can gradually and controllably dilate the anus and the anal tube of the patient and can ensure the anal sphincter to adapt to the amplitude of spreading the anus by the body of the novel anus dilator, thus avoiding anal fissure and alleviating the pains of the patient. The component can be widely applied to surgery.

Description

technical field [0001] The invention relates to a medical device, in particular to an anal dilator seat assembly for surgical operations. Background technique [0002] When performing inspection, diagnosis or surgical treatment in anorectal surgery, it is necessary to open the anus first, and then put in other inspection or treatment instruments. The commonly used tool for opening the anus at present is the anal expander seat. Its rigid cylindrical body is used to expand the anus, and the hollow part constitutes the passage for other instruments to enter. The diameter of the seat is usually relatively large. The diameter is more than 30 millimeters, and it is not easy to enter the anus. Usually, the doctor will insert the fingers first, and then forcefully stretch the anus with both hands, and then insert the anal expander seat into the anus. When the doctor pre-expands the anus with his fingers, he often damages the patient's anal sphincter muscle due to excessive force i...
