Abstract
The utility model belongs to the technical field of medical instruments and provides an anal tube surgery dilator so as to enable an anal tube to be fully dilated during anal surgery. The anal tube surgery dilator comprises a dilation cylinder and is characterized by further comprising a first dilation ring and a second dilation ring. The first dilation ring and the second dilation ring are sequentially arranged in front of the dilation cylinder and are coaxial with the dilation cylinder. The first dilation ring and the second dilation ring are identical with the dilation cylinder in diameter. The ring wall of the first dilation ring is connected with the cylinder wall of the dilation cylinder through a first supporting rib. The first supporting ring is connected with the ring wall of the second supporting ring through a second supporting rib. The first supporting rib and the second supporting rib are arranged on the cylinder face in a staggering mode, wherein the cylinder face is formed by the dilation cylinder, the first supporting ring and the second supporting ring. The anal tube surgery dilator is simple in structure and convenient to operate, has good anal tube dilation effect, and ensures that the surgery can be carried out successfully.
Description
Technical field
This utility model belongs to the medical apparatus technical field, especially relates to a kind of anal canal surgery dilator.
Background technology
At present, it is Minimally Invasive Surgery that anal canal surgery is treated local disease, anal canal need to be strutted to expose operative site during operation and facilitate the doctor to operate.The annular expansion device is normally adopted in present PPH operation, the annular expansion device of two independent separate inserts in anal canal as expanding anus and supporting, then perform the operation, but due to the parts that are two separation, thereby length deeply can not change, and the mucosa in anorectal region is easily charged in dilator, causes without the working place and affects the visual field, increase trouble to operation, make the doctor can't complete well purse string suture.
Summary of the invention
The purpose of this utility model has been to provide a kind of anal canal fully can the expansion to come, be convenient to that the doctor carries out omnibearing operation and suture needle operation, do not affect the visual field, anal canal surgery dilator simple in structure.
for realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: the anal canal surgery dilator, comprise the expansion cylinder, it is characterized in that: this dilator also be included in expansion cylinder the place ahead that set gradually with the first tensioner ring and the second tensioner ring expansion cylinder coaxial line, the first tensioner ring and the second tensioner ring are consistent with the diameter of expansion cylinder, be connected by the first supporting rib between the barrel of the ring wall of the first tensioner ring and expansion cylinder, be connected by the second supporting rib between the ring wall of the first support ring and the second support ring, the first supporting rib and the second supporting rib are expansion cylinder and first, be staggered on the second support ring formed face of cylinder.
After this utility model adopts said structure, during operation, this utility model is inserted in anal canal and support, by rotating this dilator, utilize the supporting rib on this dilator that the anal canal wall of operative site respective side is propped up, operative site is able to abundant exposure, the doctor can perform the operation and the suture needle operation omnibearing, accurately, steadily, and does not affect the visual field.This anal canal surgery dilator is simple in structure, easy to operate, and is good to the anal canal expansion effect, and what can guarantee to perform the operation carries out smoothly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, expansion cylinder, the 2, first tensioner ring, the 3, second tensioner ring, the 4, first supporting rib, the 5, second supporting rib.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in drawings, this anal canal surgery dilator comprises expansion cylinder the 1, first support ring 2 and the second support ring 3.
As shown in drawings, the diameter of the first support ring 2, the second support ring 3 is consistent with expansion cylinder 1 diameter.
As shown in drawings, the first support ring 2 and the second support ring 3 are coaxially set successively in expansion cylinder 1 the place ahead, be connected by the first supporting rib 4 between the barrel of the ring wall of the first tensioner ring 2 and expansion cylinder 1, be connected by the second supporting rib 5 between the ring wall of the first support ring 2 and the second support ring 3, the first supporting rib 4 and the second supporting rib 5 are staggered on expansion cylinder 1 and first, second support ring formed face of cylinder.
During use, this dilator is sent in anal canal, expansion cylinder 1 struts anal orifice fully, rotates expansion cylinder 1 operative site is fully exposed, and the doctor can operate by an expansion cylinder cylinder chamber.
