Embodiment Construction

[0017] Such as Figure 1-3 As shown, the anal dilator seat of the present invention includes a cone-shaped body 2 and an outwardly expanded wide side 1, the wide side 1 is connected to the proximal end of the main body 2, and the tapered structure at the distal end of the main body 2 plays a good guiding role. Function, of course, the body 2 can also be designed as a cylindrical structure. A first opening 3 that can be selectively opened or closed is provided through the body 2, and a second opening 4 that can be selectively opened or closed is also provided through the wide side 1, and the first opening 3 communicates with the first opening 3. Two openings 4; the angle α of the first opening 3 and the second opening 4 is both 5°-90°. This design allows the diameter of the outer surface of the anal dilator seat to be selectively enlarged or reduced by changing the magnitude of the grip force received, in order to prevent the doctor from clamping the two sides of the device du...

Abstract

The invention discloses an anus stretching device base. The anus stretching device base comprises a hollow body and an externally stretched wide edge, wherein the wide edge is connected with the near end of the body. The anus stretching device base is characterized in that: a first opening which can be opened or closed selectively penetrates the body; a second opening which also can be opened or closed selectively penetrates the wide edge; and the first opening is communicated with the second opening. The anus stretching device base can gradually and controllably stretch the anus and the anal tube of a patient and can adapt the anal sphincter to the amplitude stretched by the anus stretching device base before the anus stretching device base is inserted so as to prevent anal fissure and relieve the pain of the patient. At the same time, in the anus stretching device base, pre-anus stretching and anus stretching are integrally designed, so that the product is more easy and convenient to use. The anus stretching device base can be widely applied to surgical operations.

Description

technical field [0001] The invention relates to an anal dilator seat 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 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 ...
