Before the use, firstly, the tightness degree of the pulling line 202 is adjusted through the adjusting handle 11 to keep the pulling line in a loose state, a circular ring formed by a plurality of pulling parts 2 in the state is in a state with the smallest radius, and then a plurality of L-shaped plates 241 are respectively taken down from the U-shaped buckle plate 240;

when the device is used, firstly, the arc-shaped fixing piece 23 is inserted into the anus of a patient, because the arc-shaped fixing piece 23 is limited in length, only a point can be inserted into the arc-shaped fixing piece to provide primary fixing capacity for the device, and primary fixing force is formed on the device body along with the insertion of the whole length of the arc-shaped fixing piece 23, at the moment, because the annular air bag 100 arranged at the bottom of the annular shell 10 has the deformation capacity, the device can keep balance at the hip position of the patient and unevenness, then, the longer end of the L-shaped plate 241 is inserted into the U-shaped buckle 240 one by one, the short plate side of the L-shaped plate 241 is fixed according to the matching of the fixing hole 2410 arranged on the L-shaped plate 241 and the spherical convex column 242 arranged on the arc-shaped shell 22, after the four L-shaped plates 241 are inserted into the anus of the patient, the device is fixed in depth, then, the adjusting handle 11 is slowly rotated, the rotation of the adjusting handle 11 drives the driving wheel 12 to rotate, the driving wheel 12 and the outside of the double-side gear ring 13 are meshed to drive the double-side gear ring 13 to rotate, due to the meshing effect of the driven wheel 201 and the inside of the double-side gear 13, the driven wheels 201 synchronously rotate, the expansion degree of 4 traction parts is kept consistent, in the process of rotating the driven wheels 201, the rotating rod 200 starts to rotate along with the driven wheels, the traction line 202 is gradually wound, the winding of the traction line 202 drives the position of the inner tube 211 to change, further the position change of the arc-shaped shell 22 is changed, then the depth fixing component 24 on the arc-shaped shell is driven to move so as to achieve the purpose of expanding the anus of a patient, after the operation is finished, the adjusting handle 11 is reversely rotated to achieve the loosening of the traction line 202, so that the traction line does not form a pulling force on the inner tube 211 any more, at the moment, the spring 212 compressed by the inner tube 211 rebounds to push the position of the inner tube 211, and further the depth fixing component 24 returns to the initial position again, so as to facilitate the removal of the device as a whole.

Specifically, the connecting assembly 21 includes an outer tube 210, an inner tube 211 and a spring 212, one end of the inner tube 211 is fixedly connected to the outer side wall of the arc-shaped outer shell 22, the other end of the inner tube 211 is movably connected to the inside of the outer tube 210, the spring 212 is located at the inner side of the outer tube 210, and two ends of the spring are respectively fixedly connected to the outer tube 210 and the inner tube 211.

Specifically, the pulling assembly 20 includes a rotating rod 200, a driven wheel 201 and a pulling line 202, the driven wheel 201 is rotatably connected to the inner wall of the circular ring housing 10, the driven wheel 201 is fixedly connected to the rotating rod 200 and is engaged with the inner side of the double-sided toothed ring 13, one end of the pulling line 202 is fixedly connected to the rotating rod 200, and the other end of the pulling line passes through the outer tube 210 and the spring 212 and is fixedly connected to the inner tube 211;

the driven wheel 201 is indirectly driven to rotate by the active operation of the adjusting handle 11, so that the length of the pulling line 202 is controlled, the position of an inner pipe in the expansion process is controlled by the change of the length of the pulling line 202, and the size of an annular radius formed by a plurality of pulling parts 2 is changed; after the operation is finished, the pulling wire 202 is in a relaxed state through reverse operation, the inner tube 211 is restored to the initial position under the action of the self elasticity of the spring 212, and further, the annular radius formed by the pulling part 202 is in a minimum state, so that the device is convenient to take out.

Specifically, the depth fixing assembly 24 includes a U-shaped buckle 240, an L-shaped plate 241 and a spherical convex column 242, the U-shaped buckle 240 is fixedly connected to the inner wall of the arc-shaped shell 22, the spherical convex column 242 is fixedly connected to the top wall of the arc-shaped shell 22, and a short plate of the L-shaped plate 241 is provided with a fixing hole 2410 matched with the spherical convex column 242; the U-shaped buckle 240 and the spherical convex column 242 are arranged to integrally fix the L-shaped plate 241, and then the L-shaped plate 241 is inserted into the anus of the patient to achieve the purposes of depth fixation and expansion of the anus of the patient.

Specifically, the spherical convex column 242 is made of an elastic rubber material; the elastic property of the spherical convex column 242 makes the L-shaped plate 241 require a certain external force for installation and disassembly, and the change of the position and the penetration depth of the L-shaped plate 241 in the expansion process is avoided.

Specifically, a silica gel layer is attached to the outer sides of the arc-shaped fixing piece 23 and the L-shaped plate 241; because the arc-shaped fixing piece 23 and the L-shaped plate 241 are inserted into the anus of the patient in different degrees, the silica gel layer attached to the surface contacting with the inner wall of the anus can reduce the stimulation to the inner layer of the anus of the patient.

Specifically, the bottom of the circular casing 10 is fixedly connected with an annular air bag 100; because the buttocks are not a plane but a curved surface, the curved surface of the buttocks of the patient is adapted through the elastic force change of the annular air bag 100, and the integral stability of the device is kept.
