Embodiment Construction

[0020] Such as Figure 1-5 As shown, the anal dilator seat for surgery of the present invention includes a hollow body 2 and a broad side 1 that expands outward, and the wide side 1 is connected to the proximal end of the body 2, and the body 2 and the wide side of the anal dilator seat for the operation are Side 1 is a roll-shaped structure, including a positioning edge 21 and an adjusting edge 23, the outer wall of the adjusting edge 23 is close to the inner wall of the positioning edge 21, and the adjusting edge 23 can slide relatively along the inner wall of the positioning edge 21, so that The outer diameter of the grip type anal dilator seat can be selectively enlarged or reduced.

[0021] The anal dilator seat for surgery also includes a clamping piece for positioning the positioning edge 21 and the adjusting edge 23, and the clamping piece includes a set of protrusions 22 arranged on the inner wall of the positioning edge 21 and at least two sets of The clamping hole ...

Abstract

The invention discloses an anus expander seat for surgery, which is used for expanding an anus and an anal canal. The anus expander seat comprises a hollow body and an externally expanding wide edge, wherein the wide edge is connected to the near end of the body. The anus expander seat is characterized in that: the body and the wide edge of the anus expander seat for surgery have winding drum structures; each winding drum structure comprises a positioning edge and an adjusting edge which selectively move or are fixed with each other; the outer wall of the adjusting edge is firmly attached to the inner wall of the positioning edge; and the adjusting edge can slide relatively to the inner wall of the positioning edge. The anus expander seat can gradually and controllably expand the anus and the anal canal of a patient and can enable the sphincter of the anus to adapt to an amplitude opened by the anus expander seat before the anus expander seat is inserted, so that the phenomenon of anal fissure is avoided and the pain of the patient is relieved. The anus expander seat can be widely applied to surgical operation.

Description

technical field [0001] The invention relates to an anal dilator seat for operation, which belongs 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 at present is an anal expander seat, which includes a cylindrical body and a force-applying shoulder located at the tail of the body. The hollow portion forms a passage 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 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 expander seat It is not easy to enter the anus. The existing common way is that t...
