[0002] Anal dilation therapy is a medical procedure that is usually used to treat some anal and rectal problems, such as anal fissures and anal stenosis. This treatment method dilates the anus and rectum to relieve symptoms or promote healing. Anal dilators are a common medical device during anal surgery. Its main function is to dilate the patient's anus, making it easier for medical staff to perform surgical treatment or diagnosis on the patient's anus.

[0003] When using the existing anal dilator, the operator needs to manually squeeze the two grips to open the dilator. However, during the entire operation, the expansion state of the dilator needs to be maintained according to the strength of the operator's hand. After the dilator is opened, if the medical staff's hands cannot be released and they keep holding the grips, their hands will become sore and unable to expand better, which may cause unexpected situations during the operation. Summary of the invention

[0008] As a further solution of the utility model, connecting plates are installed at the front and rear ends of one side of the support plate, and a sealing ring is fixedly installed in the internal circular hole of the connecting plate.

[0009] As a further solution of the utility model, the middle part of the upper end of the support plate is arc-shaped.

[0010] As a further solution of the utility model, one end of the screw rod away from the rotating seat is fixedly connected to a handle.

[0011] As a further solution of the utility model, anti-slip pads are installed on one side of the first handle and the second handle.

[0012] As a further solution of the utility model, the anti-slip pad is located in a groove on one side of the first handle and the second handle.

[0013] The beneficial effects of the utility model are as follows:

[0014] By setting a locking structure, the patient's anus can be slowly expanded by rotating the screw rod, avoiding the sudden expansion of the anus caused by manually squeezing the two grips, reducing the patient's discomfort during expansion. At the same time, after expansion, there is no need to continue to hold the expander by hand, which can achieve the purpose of locking and facilitate the release of the hands of medical staff;

[0015] By setting up a stable structure, when the bottom end of the expansion plate enters the patient's anus, the support plate is rotated to make the support plate parallel, so that the lower end of the support plate contacts the skin around the anus, so that the two sets of expansion plates can be stably erected directly above the patient's anus, ensuring the stability of the expansion plate after entry.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, an anal dilator for anorectal surgical operations comprises a first expansion plate 1 and a second expansion plate 2, wherein a first gripping rod 3 and a second gripping rod 4 are fixedly mounted on the front ends of the first expansion plate 1 and the second expansion plate 2, respectively, a connecting seat 5 is fixedly mounted on one side of the first gripping rod 3, one end of the second gripping rod 4 is rotatably connected to one side of the first gripping rod 3, a locking structure 6 is arranged inside the second gripping rod 4, and the locking structure 6 comprises a screw rod 7, one end of the screw rod 7 is rotatably connected to a rotating seat 8, a vertical rod 9 is mounted on the inner wall of one side of the first gripping rod 3, and the rotating seat 8 is rotatably arranged on the outer wall of the vertical rod 9.

[0023] In this embodiment, a stabilizing structure 10 is disposed on one side of the first expansion plate 1 and the second expansion plate 2 , and the stabilizing structure 10 includes a fixing rod 11 , and a supporting plate 12 is disposed on an outer wall of the fixing rod 11 .

[0024] The fixing rod 11 is used to rotate and install the support plate 12. After the support plate 12 is opened, it can contact the patient's skin more firmly, ensuring that the expansion plate is placed firmly, making it more convenient for medical staff to treat the patient's anus.

[0025] In this embodiment, connecting plates 13 are installed at the front and rear ends of one side of the support plate 12 , and a sealing ring 14 is fixedly installed in the inner circular hole of the connecting plate 13 .

[0026] The connecting plate 13 is used to be connected to the fixing rod 11 , and the sealing ring 14 can prevent the supporting plate 12 from flipping and shaking by itself when the supporting plate 12 sags.

[0027] In this embodiment, the middle portion of the upper end of the support plate 12 is arc-shaped.

[0028] In this embodiment, one end of the screw rod 7 away from the rotating seat 8 is fixedly connected with a handle.

[0029] The handle allows the operator to easily rotate the screw rod 7, thereby limiting the position between the two sets of expansion plates.

[0030] In this embodiment, an anti-slip pad 15 is installed on one side of the first handle bar 3 and the second handle bar 4 .

[0031] The anti-skid pad 15 helps the operator to hold the first handle 3 and the second handle 4 more stably.

[0032] In this embodiment, the anti-slip pad 15 is located in a groove on one side of the first handle bar 3 and the second handle bar 4 .

[0033] It should be noted that the utility model is an anal dilator for anorectal surgery. When in use, the first dilator plate 1 and the second dilator plate 2 are disinfected, and the first dilator plate 1 and the second dilator plate 2 are inserted into the patient's anus. When dilating, the medical staff does not need to manually squeeze the two gripping rods, but only needs to slowly rotate the handle so that one end of the screw rod 7 drives the first gripping rod 3 to move to one side, thereby realizing the opening of the first dilator plate 1 and the second dilator plate 2, thereby dilating and opening the patient's anus, which is convenient for the medical staff to perform treatment later;

[0034] During the whole process, there will be no discomfort to the patient due to the operator's strong hand force and the instantaneous expansion of the anus. At the same time, after the expansion, the medical staff does not need to continue to manually hold the first grip rod 3 and the second grip rod 4, so that the hands can be released, which relatively reduces the pressure burden on the hands of the medical staff.

[0035] When the first expansion plate 1 and the second expansion plate 2 are opened, the support plate 12 is flipped over so that the support plate 12 reaches a balanced state, and the support plate 12 is limited so that both sides of the first expansion plate 1 and the second expansion plate 2 have a support surface with the patient's skin. The opening of the two groups of support plates 12 and the placement of the first grip rod 3 and the second grip rod 4 can ensure that the overall device is more firmly positioned in the patient's anus.

[0036] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
