Description

Anal dilator seat

technical field

The utility model relates to an auxiliary device for surgical operations, in particular to an anal expander seat, which belongs to the technical field of medical devices.

Background technique

Anal dilator seat is a commonly used auxiliary device in anorectal department, which plays an important role in anorectal examination and surgical treatment. Further, the current anal dilator seat is a straight cylindrical structure with edges, and its edges are controlled by doctors or directly fixed with the skin of the anal edge. The function of the anal dilator seat is to open the anus and prepare for follow-up examination or treatment. However, the instrument of this structure has a single function. In order to facilitate the use of the operation, it also needs to be used together with a cylindrical auxiliary catheter with a tapered end, especially in non-circular cutting hemorrhoid surgery. In such a situation, the steps of the operation are numerous, which is not conducive to the rapid implementation of the operation, and indirectly increases the pain of the patient.

Contents of the invention

The purpose of the utility model is to overcome the above problems existing in the prior art and provide a multifunctional anal dilator seat.

In order to realize the object of the utility model, the anal dilator seat includes a cylindrical body and a wide side, and the wide side is connected to the proximal end of the cylindrical body, wherein: the distal end of the cylindrical body is provided with a cap.

Further, the above-mentioned anal dilator seat, wherein, the cap includes a tapered crown and a cap body, and the cap body is provided with slots.

Furthermore, in the above-mentioned anal dilator seat, the said slot occupies 1/6-5/6 of the circumference of the cylinder body.

Furthermore, the above-mentioned anal dilator seat, wherein, the cap and the anal dilator seat are integrated, and the cap body extends from the distal end of the cylindrical body to the top of the cap.

Furthermore, the above-mentioned anal dilator seat, wherein, the cap and the anal dilator seat are split, and the cylindrical body and the cap body are connected by buckles or threads.

Furthermore, the above-mentioned anal dilator seat, wherein, two handles are arranged on the broad side of the anal dilator seat.

Still further, the above-mentioned anal dilator seat, wherein, the cap top of the anal dilator seat is a closed or non-closed structure.

Adopting the technical scheme of the utility model, in the whole operation process, compared with the same operation done by using the traditional anal expander seat, two instruments, the inner catheter of the anal expander and the anoscope, are saved, and then the use of these two instruments is eliminated. The process of two instruments simplifies the operation steps and saves operation time. Moreover, the circular tube-type hemorrhoid binding instrument can be used for non-circular cutting hemorrhoid surgery, so that the application range of the circular tube-type hemorrhoid binding instrument is expanded, the operation effect is further guaranteed, and it is suitable for popularization and use in the industry.

The objects, advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments, which are given by way of example only with reference to the accompanying drawings.

Detailed ways

The anal dilator seat shown in Figures 1 to 4 includes a cylindrical body 1 and a wide side 2, and the wide side 2 is connected to the proximal end of the cylindrical body 1, and its special feature is that: the cylindrical body 1 The distal end is provided with a cap. The cap includes a tapered crown 3 and a cap body 4, and the cap body 4 is provided with slots. Further, as shown in FIG. 1 , the cap and the dilator seat are integrally constructed, and the cap body 4 extends from the distal end of the cylindrical body 1 to the cap top 3 . Alternatively, in order to facilitate the assembly and replacement of the device, the cap and the dilator seat can also be of a split structure, as shown in Figures 2-4, the cap body 4 is provided with buckles 5, and on the cylindrical body 1 A card slot 6 is provided, and the cylindrical body 1 and the hat body 4 are connected by a card buckle. In order to facilitate the effective accommodation of the hemorrhoid tissue, the slots account for 1/6-5/6 of the circumference of the cylinder body. Of course, the cylindrical body 1 and the hat body 4 can also be connected by threads or in other ways. In order to make it easier for the doctor to hold the anal expander seat, two handles 7 are set on the wide side of the anal expander seat. Further, for the convenience of the doctor to observe, the anal expander seat is set to be transparent, so that the visual field is not affected by others during the operation. In order to avoid the influence of tissue, the cap and cap body at the end of the anal dilator seat are set to be non-transparent, and the cap is a closed or non-closed structure.

Seen in conjunction with Fig. 1 or Fig. 4: take the anorectal non-circular cutting hemorrhoid surgery as an example to illustrate the use of this device. First, the cap of the anal dilator seat is directed towards the anus, so that the tapered cap top 3 is inserted into the anal canal. Then, the anal dilator seat is pushed into the anal canal in a rotating manner, so that the hemorrhoid tissue waiting to be cut falls on the grooved area of the cap body 4 of the anal dilator seat. Then the broadside 2 of the anal expander seat is sewed up with the skin on the anus limit, so as to achieve the purpose of fixing the anal expander seat. Further, the hemorrhoid tissue at the groove of the anal dilator seat is purse-string sutured with clamps to hold the curved needle. Then make the stapling instrument enter the anal canal from the anal dilator seat, make the hemorrhoid tissue fall in the suture area between the staple anvil and the staple bin of the stapling instrument, and then pull the purse string to ensure that all the hemorrhoid tissue is accommodated in the suture area of the stapling instrument Then adjust the distance between the staple anvil and the staple bin so that the hemorrhoid tissue is sandwiched between the anvil and the staple bin. Immediately afterwards, the firing handle of the stapling instrument is operated, the staples of the stapling instrument are fired to the tissue, and the hemorrhoid tissue is excised at the same time, and finally the instrument is withdrawn.

It can be seen from the above text description and in conjunction with the accompanying drawings that in the whole operation process, compared with the same operation using the traditional anal dilator seat, two instruments, the anal dilator inner catheter and the anus mirror, are omitted, and then The process of using these two instruments is eliminated, the operation steps are simplified, and the operation time is saved. Moreover, the circular tube-type hemorrhoid binding instrument can be used for non-circular cutting hemorrhoid surgery, so that the application range of the circular tube-type hemorrhoid binding instrument is expanded, the operation effect is further guaranteed, and it is suitable for popularization and use in the industry.

Of course, the above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
