[0052] Embodiment one

[0053] The dilator is a necessary instrument for the surgical operation or anorectal examination of anorectal diseases.In order to ensure the accuracy of the operation or examination, the lesion site needs to be illuminated.Due to the poor control and exposure of the field of view at the anus during the operation, the doctor needs to wear a head lamp to illuminate the operation field of view, but during the process of wearing the head lamp to irradiate the lesion, the doctor needs to swing the head to observe the lesion according to the actual needs, which causes the head lamp to swing with the head, affecting the illumination effect of the lesion.In order to realize the stable irradiation of the lesion site, the existing scheme also proposes a scheme of setting a direct light source on the barrel of the dilator, but the direct light source not only directly irradiates the lesion inward, but also directly irradiates the doctor's eyes outward, which not only easily causes eye fatigue, but also greatly affects the normal observation of the lesion site.In addition, the dilator of the existing scheme can only provide a fixed size of operation window, and in the actual operation process, the size of the operation window needs to be adjusted according to the actual lesion size, but the dilator of the existing scheme cannot meet the actual needs.

[0054] To solve the above problems, as shown in Figures 1-8 The anus dilator includes an anus dilator 100, a matching piece 200, and a lighting lamp 300. The anus dilator 100 has a dilating part 110 and a fixing part 120 connected in sequence along an axial direction. The side wall of the dilating part 110 has a first window 111. The matching piece 200 is rotationally connected with the anus dilator 100 around the axial direction. The matching piece 200 includes a matching part 210 and a limiting part 220 connected in sequence along the axial direction. The dilating part 110 is arranged outside the matching part 210. The fixing part 120 is arranged outside the limiting part 220. The side wall of the matching part 210 has a second window 211. The facing area of the first window 111 and the second window 211 is adjustable. The lighting lamp 300 is arranged between the fixing part 120 and the limiting part 220 along the axial direction. The anus dilator 100 and the matching piece 200 are made of transparent materials. The surface of the fixing part 120 is provided with a first reflection area. The surface of the limiting part 220 is provided with a second reflection area. The first reflection area and the second reflection area form an irradiation path. One end of the irradiation path faces the lighting lamp 300. The other end of the irradiation path faces the lesion.

[0055] The anus dilator includes an anus dilator 100, a matching piece 200, and a lighting lamp 300. The anus dilator 100 has a dilating part 110 and a fixing part 120 connected in sequence along an axial direction. The side wall of the dilating part 110 has a first window 111. The matching piece 200 is rotationally connected with the anus dilator 100 around the axial direction. The matching piece 200 includes a matching part 210 and a limiting part 220 connected in sequence along the axial direction. The dilating part 110 is arranged outside the matching part 210. The fixing part 120 is arranged outside the limiting part 220. The side wall of the matching part 210 has a second window 211. The facing area of the first window 111 and the second window 211 is adjustable. The lighting lamp 300 is arranged between the fixing part 120 and the limiting part 220 along the axial direction. The anus dilator 100 and the matching piece 200 are made of transparent materials. The surface of the fixing part 120 is provided with a first reflection area. The surface of the limiting part 220 is provided with a second reflection area. The first reflection area and the second reflection area form an irradiation path. One end of the irradiation path faces the lighting lamp 300. The other end of the irradiation path faces the lesion.

[0056] It should be noted that in the present embodiment, the illumination lamp 300 is annular, and the expansion portion 110 and the matching portion 210 pass through the through hole of the annular illumination lamp 300 respectively, so that the illumination lamp 300 irradiates the lesion along the radial direction of the expansion portion 110 and the matching portion 210, thereby improving the illumination effect.

[0057] As shown in Figure 1 and Figure 3 , the above figures respectively show the case that the facing area between the first window 111 and the second window 211 is zero, the facing area between the first window 111 and the second window 211 is half of the second window 211, and the facing area between the first window 111 and the second window 211 is the entire area of the second window 211. It can be understood that when it is necessary to increase or decrease the actual working window size of the dilator, the rotation angle of the dilator 100 and the matching member 200 around the axis is adaptively adjusted by rotating the matching member 200 around the axis relative to the dilator 100, and the present embodiment is not limited in particular.

[0058] Specifically, as shown in Figures 4-8 , the illumination lamp 300 is located between the inner surface of the fixed portion 120 and the inner surface of the limiting portion 220, the inner surface of the fixed portion 120 includes a facing area and a misalignment area, the facing area is arranged in axial alignment with the illumination lamp 300, and the misalignment area is arranged in axial misalignment with the illumination lamp 300, the first reflection area includes the misalignment area and the outer surface of the fixed portion 120, and the second reflection area includes the inner surface of the limiting portion 220 and the outer surface of the limiting portion 220. By arranging the illumination lamp 300 between the inner surface of the fixed portion 120 and the inner surface of the limiting portion 220, the inner surface of the fixed portion 120 is divided into the facing area arranged in axial alignment with the illumination lamp 300 and the misalignment area arranged in axial misalignment, the first reflection area is formed by the misalignment area and the outer surface of the fixed portion 120, and the second reflection area is formed by the outer surface and the inner surface of the limiting portion 220, so that the light emitted by the illumination lamp 300 can only enter the illumination path along the facing area and irradiate the lesion.

[0059] It should be noted that in the present embodiment, the first reflection area and the second reflection area are both obtained by sanding. After sanding the corresponding areas of the fixed portion 120 and the limiting portion 220, the corresponding areas cannot make the light pass through the sanding layer and propagate to the outside, so that the light emitted by the illumination lamp 300 cannot directly shine into the eyes, and since the dilator 100 and the matching member 200 are both made of transparent material, the light cannot pass through the sanding layer but can be reflected along the sanding layer, so as to achieve the effect that the light irradiates the lesion along the reflection path.

[0060] In addition, in other embodiments, the light-reflecting surface of the light-reflecting film can be formed by pasting the light-reflecting film on the surface corresponding to the first and second reflection areas, so that the light-reflecting surface forms the illumination path, and the light emitted by the illuminating lamp 300 can be reflected on the light-reflecting surface to illuminate the lesion.

[0061] Alternatively, the radial dimension of the expansion portion 110 gradually decreases along the axial direction away from the fixing portion 120, and the radial dimension of the matching portion 210 gradually decreases along the axial direction away from the limiting portion 220, so that the expansion portion 110 and the matching portion 210 are both in the shape of a cone, which can facilitate the doctor to observe the lesion outside the sidewall of the expansion portion 110 and the matching portion 210 from the end away from the expansion portion 110 along the axial direction, and facilitate the subsequent treatment of the lesion.

[0062] In an alternative, the fixing portion 120 is provided with a threading hole 121 penetrating along the axial direction. After the expansion portion 110 is inserted into the anus, in order to avoid the expansion portion 110 from being separated from the anus, a surgical thread is sequentially threaded through the threading hole 121 and the surrounding tissue to prevent the expansion portion 110 from being separated from the anus.

[0063] In order to further improve the fixing effect of the expansion portion 110, the fixing portion 120 is provided with at least two threading holes 121 arranged at intervals, and each threading hole 121 is sutured and fixed to the surrounding tissue by a surgical thread. It should be noted that in the present embodiment, the fixing portion 120 is provided with two threading holes 121, and the two threading holes 121 are oppositely arranged. In other embodiments, the specific number of threading holes 121 can be adjusted according to actual needs, and the present embodiment is not limited in this regard. In addition, in other embodiments, the threading hole 121 can be replaced by a buckle structure fixed on the fixing portion 120, and the buckle structure is buckled and fixed to the surrounding tissue to achieve the fixation of the anal dilatation device 100.

[0064] In order to further prevent the expansion portion 110 from being separated from the anus, the end of the expansion portion 110 close to the fixing portion 120 is provided with a threaded protrusion 112, which is arranged along the axial direction around the circumference of the expansion portion 110. The threaded protrusion 112 increases the friction between the expansion portion 110 and the anus, thereby preventing the expansion portion 110 from being separated from the anus.

[0065] As Figure 7 and Figure 9As shown, the expansion part 110 is provided with a positioning groove 113 recessed in the radial direction near the inner cavity wall of the fitting part 210, the positioning groove 113 forms a closed ring around the axial direction, the fitting part 210 is provided with a positioning protrusion 212 extending in the radial direction away from one end of the limiting part 220 in the axial direction, the positioning protrusion 212 is in axial clamping fit with the positioning groove 113, and the positioning protrusion 212 can rotate along the positioning groove 113. By providing the positioning groove 113 extending in the axial direction near the inner cavity wall of the fitting part 210, the positioning groove 113 forms a closed ring, and the positioning protrusion 212 extending outward in the radial direction is arranged at one end of the fitting part 210 away from the limiting part 220 in the axial direction, the positioning protrusion 212 and the positioning groove 113 are clamped together and rotate along the positioning groove 113, which realizes the effect that the anal dilating device 100 is clamped and fixed with the fitting device 200 in the axial direction while the anal dilating device 100 rotates relative to the fitting device 200 around the axial direction, and the structure is simple and has high structural strength.

[0066] In the assembly process of the anal dilating device 100 and the fitting device 200, the positioning protrusion 212 and the positioning groove 113 need to be clamped together in the axial direction, and in this process, the positioning protrusion 212 will drive the fitting part 210 to deform in the radial direction. In order to facilitate the clamping of the positioning protrusion 212 and the positioning groove 113, the fitting part 210 is provided with a deformation groove 214 at one end away from the limiting part 220 in the axial direction, the deformation groove 214 is recessed in the axial direction near the limiting part 220, and the deformation groove 214 can provide a deformation space for the deformation of the fitting part 210. When the positioning protrusion 212 drives the fitting part 210 to deform in the radial direction, the fitting part 210 can compress the space of the deformation groove 214 to provide a deformation space for the deformation of the fitting part 210, thereby avoiding the rupture of the fitting part 210 during the deformation process and improving the protection of the fitting part 210.

[0067] In addition, the fitting part 210 is provided with at least two positioning protrusions 212 and at least two deformation grooves 214, the at least two positioning protrusions 212 are arranged on the fitting part 210 at intervals around the axial direction, the at least two deformation grooves 214 are arranged on the fitting part 210 at intervals around the axial direction, and one deformation groove 214 is arranged between adjacent two positioning protrusions 212. By arranging the at least two positioning protrusions 212 and the at least two deformation grooves 214 on the fitting part 210 at intervals around the axial direction, one deformation groove 214 is arranged between adjacent two positioning protrusions 212, which not only realizes the simultaneous clamping and sliding connection of the at least two positioning protrusions 212 with the positioning groove 113, but also further improves the protection of the fitting part 210. It should be noted that in the present embodiment, the fitting part 210 is provided with three positioning protrusions 212 and three deformation grooves 214 at intervals around the axial direction. In other embodiments, the specific number of positioning protrusions 212 and deformation grooves 214 can be adjusted according to actual needs, and the present embodiment does not make specific limitations.

[0068] As an optional solution, asFigure 10 As shown, the surface of the fitting part 210 is provided with an axial scale line 213. By providing the axial scale line 213 on the surface of the fitting part 210, not only the insertion depth of the expanding part 110 can be quickly determined, but also the depth of the lesion can be quickly determined, which facilitates subsequent processing of the lesion.

[0069] In combination Figure 11 The specific structure of the illumination lamp 300 will be described. The illumination lamp 300 includes a bulb structure 310, a first cover 320, and a second cover 330. The first cover 320 and the second cover 330 are axially fixed together and form an accommodation space. The bulb structure 310 is accommodated in the accommodation space. The first cover 320 is located at one end of the second cover 330 axially close to the expanding part 110. The first cover 320 is made of transparent material. By setting the first cover 320 and the second cover 330 axially fixed together, the accommodation space is formed between the first cover 320 and the second cover 330. The bulb structure 310 is accommodated in the accommodation space, which realizes safe accommodation of the bulb structure 310 and improves protection of the bulb structure 310. By locating the first cover 320 at one end of the second cover 330 axially close to the expanding part 110 and making the first cover 320 of transparent material, the light emitted by the bulb structure 310 can pass through the first cover 320 and enter the illumination path. It should be noted that in the embodiment, the second cover 330 is made of transparent material, and the surface of the second cover 330 is frosted. When the light emitted by the bulb structure 310 is irradiated on the frosted surface of the second cover 330, the amount of refraction of the light through the second cover 330 can be reduced and the amount of reflection of the light relative to the second cover 330 can be increased in the frosted surface. Not only can the direct light of the light through the second cover 330 be prevented from directly shining into the eyes, but also the reflected light of the light along the second cover 330 can be irradiated on the lesion, which further improves the illumination effect on the lesion. In other embodiments, the second cover 330 can also be made of non-transparent material to strengthen the reflection of the light on the second cover 330 and weaken the refraction of the light on the second cover 330. The embodiment is not limited specifically. In addition, the bulb structure 310 includes a bulb, a circuit board, and other structures in the prior art. To ensure the brevity of the behavior, no further description is given here.

[0070] In an optional solution, as Figure 12 and Figure 13As shown, the anal dilator further comprises an adapter plug 400, an adapter socket 500 and a power supply 600, wherein any one of the adapter plug 400 and the adapter socket 500 is connected with the bulb structure 310 in the illuminating lamp 300, the other one is connected with the power supply 600, the adapter plug 400 can be plugged and fixed with the adapter socket 500, and the adapter plug 400 and the adapter socket 500 are used for transmitting power. By connecting the adapter plug 400 and the adapter socket 500 with the bulb structure 310 and the power supply 600 respectively, and by using the butt joint of the adapter plug 400 and the adapter socket 500, the effect of transmitting power from the power supply 600 to the bulb structure 310 is achieved, so as to realize the continuous lighting of the bulb structure 310 and meet the continuous lighting demand of the illuminating lamp 300. It should be noted that in the embodiment, the adapter plug 400 is connected with the bulb structure 310, and the adapter socket 500 is connected with the power supply 600. In other embodiments, the adapter plug 400 can be connected with the power supply 600, and the adapter socket 500 can be connected with the bulb structure 310, and the embodiment is not limited in particular.
