Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an auxiliary tool for anal surgery. Background Technology

[0002] In current anorectal surgeries, medical staff typically use tape to stick the tape to both sides of the groin and then expand it outwards before attaching it to the skin on both sides of the patient's buttocks. This is extremely inconvenient to operate on, and the degree of expansion needs to be adjusted frequently during the surgery, which is not only difficult to adjust but also causes discomfort to the patient due to the repeated application and removal of the tape.

[0003] Chinese patent CN219439238U discloses an auxiliary tool for anal surgery, which includes a dilating ring and a tension band fixed to both ends of the dilating ring. The tension band has an adjusting buckle for adjusting its length. The dilating ring includes a first ring portion, a second ring portion, and an adjusting member for connecting the first and second ring portions. Expansion pads are respectively provided at opposite ends of the first and second ring portions. This design can address some of the shortcomings of the aforementioned manual dilation methods, but it still has certain deficiencies.

[0004] The expansion ring in this design is made of a non-flexible material, requiring an additional rubber ring to mitigate any potential damage to human tissue.

[0005] In addition, the product has attempted to improve these shortcomings by adding two ring-shaped hip support beams that can be formed together with the first and second rings to create two circular shapes. Although the two circular structures can expand the hips of the human body, a narrow π-shaped space is formed in the middle of the two circular structures. In actual experiments, it was found that this would affect the surgical field of vision and the surgeon's operating space. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary tool for anal surgery that can effectively solve the above-mentioned problems.

[0007] This utility model is achieved through the following technical solution: an auxiliary tool for anal surgery, which includes a dilating ring and elastic bands connected to both ends of the dilating ring;

[0008] The expansion ring includes a left ring portion, a right ring portion, and a locking member for connecting the left ring portion and the right ring portion; the left ring portion and the right ring portion are engaged and locked by the locking member to form an expansion ring with an adjustable aperture size;

[0009] The left part of the left ring is provided with a left support pad, and the left ring and the left support pad are connected by a left flexible rod; the right part of the right ring is provided with a right support pad, and the right ring and the right support pad are connected by a right flexible rod.

[0010] The left and right support pads are connected by an elastic band.

[0011] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0012] 1. The dilation ring and the expansion pad are connected by a flexible rod, which has a certain degree of plasticity. Before use, the rod is plasticized to make the dilation ring and the expansion pad fit the contour of the buttocks after the anus is opened, reducing the inconvenience caused by poor fit of the dilation ring during surgery.

[0013] 2. The left and right annular portions form a ring structure with a large surgical field of view and surgical operation space.

[0014] 3. An expansion handle structure has been added to the expansion pad, making expansion easier and more efficient. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0022] like Figures 1 to 5 As shown, an auxiliary tool for anal surgery includes a dilating ring 1 and elastic bands 2 connected to both ends of the dilating ring 1;

[0023] The expansion ring 1 includes a left ring portion 11, a right ring portion 12, and a locking member 13 for connecting the left ring portion 11 and the right ring portion 12; the left ring portion 11 and the right ring portion 12 are engaged and locked by the locking member 13 to form an expansion ring 1 with an adjustable aperture size;

[0024] The left ring 11 is provided with a left support pad 14 on the left side, and the left ring 11 and the left support pad 14 are connected by a left flexible rod 3; the right ring 12 is provided with a right support pad 15 on the right side, and the right ring 12 and the right support pad 15 are connected by a right flexible rod 4.

[0025] The left support pad 14 and the right support pad 15 are connected by an elastic band 2. The left flexible rod 3 and the right flexible rod 4 are metal gooseneck tubes.

[0026] Using a flexible rod can also avoid the need for an additional rubber ring as required in the original design. The flexible rod has a certain degree of deformation capability, which can adjust the position between the expansion ring and the expansion pad. When the expansion pad is fixed to the buttock, the expansion ring 1 can better fit the buttock, improving the stability of the surgery.

[0027] This design allows the dilation ring to form a ring structure at the anus, providing a large surgical field of view and surgical operation space.

[0028] The locking element 13 includes a snap-fit ​​groove 131 at the end of the left ring portion 11 and a plug-in portion 132 at the end of the right ring portion 12. The snap-fit ​​groove 131 has multiple plug-in holes 134, and the plug-in portion 132 has positioning holes 133. By adjusting the positioning holes 133 to correspond with different plug-in holes 134, and then locking them with plug-in pins 135, the size of the expansion ring 1 can be adjusted. This design allows for easier adjustment of the positions of the left and right ring portions, thereby adjusting the size of the expansion ring 1.

[0029] In practical use, the left and right ring parts are first connected via the snap-fit ​​groove and insertion part, and the flexible rod is then shaped to better conform to the patient's buttock contour. The patient is then positioned surgically, and the buttocks are opened by hand to expose the anus. Simultaneously, the device is placed on the patient's buttocks, ensuring the expansion pad adheres to the skin. Although the buttock tissue may retract, the device's support limits this retraction, preserving visibility at the anus. Finally, the elastic band is locked to secure the position of the expansion ring.

[0030] The left expansion pad 14 is provided with a left expansion handle 141, and the right expansion pad 15 is provided with a right expansion handle 151. The handle structure can assist in expansion, making the expansion operation easier.

[0031] The elastic band 2 includes a left elastic band 21 and a right elastic band 22;

[0032] The left elastic band 21 is connected to the left expansion pad 14, and the right elastic band 22 is connected to the right expansion pad 15. The elastic bands are designed to stably connect the expansion ring to the buttocks; without them, the expansion ring may fall off during the procedure.

[0033] The diagram shows two loops of left and right elastic bands, but it can also be set to one loop of left and right elastic bands.

[0034] Both the left support pad 14 and the right support pad 15 are provided with elastic band fixing rings 23, and the left elastic band 21 and the right elastic band 22 are fixedly connected by the elastic band fixing rings 23.

[0035] Both the left elastic band 21 and the right elastic band 22 are provided with Velcro straps for connecting them. The fixing method can be Velcro straps or other connection methods, which can be modified according to requirements.

[0036] In summary, after finding the appropriate degree of expansion, the doctor uses a magic pull-out adhesive tape to fix the elastic band and maintain the degree of expansion.

[0037] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
