[0027] Such as figure 1 As shown, the anal dilator includes a hollow body and an outwardly expanded broadside 2, the wideside 2 is connected to the proximal end of the body, and the body consists of at least two groups of anal dilators that cooperate with each other and have a gap 14 between them. Sheet 1 is formed, and anal expansion sheet 1 can be three or also can be four of this preferred embodiment, is evenly distributed in the far-end of broadside 2.

[0028] Rectangular or trapezoidal gaps 15 for surgical observation or surgical treatment are provided between the anal expansion pieces 1, and the gaps 15 communicate with the gaps 14, forming a character similar to a "middle" in the figure. The effect of this gap 15 is to make the anal expansion piece have good elasticity, and can return to normal state after being deformed, and the larger gap in the middle can be used for operation window or observation window.

[0029] Further, the anal expansion piece 1 includes a str...

[0036] The main structure of the anal dilator in this embodiment is the same as that in the first embodiment, so the same parts will not be repeated.

[0037] The parts that are different from the first embodiment in this embodiment are as follows: Figure 2-4 As shown, a boss 13 is provided on the inner wall of the far end of the anal expansion sheet 1, and a line hole 131 is provided on the boss 13, and a puller wire 3 is connected to the wire hole 131, and the other ends of the puller wire 3 are connected to At the distal end of the same central line 4. In this embodiment, the boss 13 is arranged at the junction of the straight section 12 and the curved section 11 .

[0038] In this embodiment, the pulling wires 3 are of equal length, and all the pulling wires 3 are connected to the same point at the distal end of the central line 4 . Therefore, the anal dilator always takes its axis as the axis of symmetry during use, and no twisting occurs.

[0039] The anal dilator in...

Abstract

The invention discloses an anus dilatation device for a surgical operation, comprising a hollow body and an outward-expanding broadside, wherein the broadside is connected to the near end of the body, the body comprises at least two groups of matched anus dilatation sheets between which a gap exist, and therefore the far ends of the anus dilatation sheets become gathered together from mutually departing. The anus dilatation device can gradually and controllably dilatate the anus and the anal tube of a patient so as to avoid anal fissure and lighten the pain of the patient. Meanwhile, the processes of anus pre-dilataton and anus dilatation are integrally designed, and thus the product is convenient and simple to use. The anus dilatation device can be widely applied in the 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 commonly used surgical instrument for stretching the anus at present 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 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 expande...
