[0003] In the related art, since the visual field of the anus is difficult to control and expose during the operation, the doctor needs to bring an additional headlamp to illuminate the surgical field of view. However, when wearing the headlamp to irradiate the lesion, the doctor needs to swing his head according to actual needs to observe the lesion, causing the headlamp to swing continuously with the head, affecting the lighting effect on the lesion. In order to achieve stable irradiation of the lesion site, the existing scheme also proposes a scheme of setting a direct light source on the barrel of the anal dilator. However, 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 anal dilator of the existing scheme can only provide an operating window of a fixed size. In the actual operation process, the size of the operating window needs to be adjusted according to the actual lesion size, but the anal dilator of the existing scheme cannot meet the actual needs.

[0052] Embodiment 1

[0053] The anal dilator is an essential instrument for surgical operations or anorectal examinations of anorectal diseases. In order to ensure the accuracy of the operation or examination, the lesion site needs to be illuminated. Since the field of vision at the anus is difficult to control and expose during the operation, the doctor needs to bring an additional headlamp to illuminate the surgical field of view. However, when wearing the headlamp to irradiate the lesion, the doctor needs to swing his head according to actual needs to observe the lesion, causing the headlamp to swing continuously with the head, affecting the lighting effect of the lesion. In order to achieve stable irradiation of the lesion site, the existing scheme also proposes a scheme of setting a direct light source on the barrel of the anal dilator, but the direct light source not only directly irradiates the lesion inward, but also directly irradiates the doctor's eyes outward, which is not only easy to cause eye fatigue, but also greatly affects the normal observation of the lesion site. In addition, the anal dilator of the existing scheme can only provide an operating window of a fixed size. In the actual operation process, the size of the operating window needs to be adjusted according to the actual lesion size, but the anal dilator of the existing scheme cannot meet the actual needs.

[0054] In order to solve the above problems, Figures 1 to 8 As shown, this embodiment provides an anal dilator. The anal dilator comprises an anal dilator 100, a matching piece 200 and an illuminating lamp 300, wherein the anal dilator 100 comprises an expansion part 110 and a fixing part 120 connected in sequence along the axial direction, the side wall of the expansion part 110 comprises a first window 111, the matching piece 200 is rotatably connected to the anal dilator 100 around the axial direction, the matching piece 200 comprises a matching part 210 and a limiting part 220 connected in sequence along the axial direction, the expansion part 110 is arranged outside the matching part 210, the fixing part 120 is arranged outside the limiting part 220, and the matching part 210 is arranged outside the limiting part 220. The side wall has a second window 211, and the facing area of ​​the first window 111 and the second window 211 is adjustable. The lighting lamp 300 is axially clamped between the fixing portion 120 and the limiting portion 220. The anal expander 100 and the matching member 200 are both made of transparent material. The surface of the fixing portion 120 is provided with a first reflecting area, and the surface of the limiting portion 220 is provided with a second reflecting area. The first reflecting area and the second reflecting area form an irradiation path, and one end of the irradiation path is opposite to the lighting lamp 300, and the other end of the irradiation path is opposite to the lesion.

[0055] The anal dilator is provided with an anal dilator 100 and a matching piece 200 which are connected and rotated around the axial direction, the anal dilator 100 is provided as an expansion part 110 and a fixing part 120 which are sequentially connected along the axial direction, and the matching piece 200 is provided as a matching part 210 and a limiting part 220 which are sequentially connected along the axial direction, so that the expansion part 110 is provided outside the matching part 210, and the fixing part 120 is provided outside the limiting part 220, and it is ensured that the side wall of the expansion part 110 is provided with a first window 111, and the side wall of the matching part 210 is provided with a second window 211, when the anal dilator 100 and the matching piece 200 are relatively rotated around the axial direction, the facing area of ​​the first window 111 and the second window 211 can be changed to adjust the actual operation window of the anal dilator to meet the requirements of the anal dilator. In order to meet the operation requirements of lesions of different specifications, the irradiation lamp 300 is axially clamped between the fixing part 120 and the limiting part 220, a first reflection area is set on the surface of the fixing part 120 in the anal dilator 100 made of transparent material, and a second reflection area is set on the surface of the limiting part 220 in the matching part 200 made of transparent material. An irradiation path is formed by using the first reflection area and the second reflection area, so that one end of the irradiation path is opposite to the lesion, and the other end of the irradiation path is opposite to the irradiation lamp 300. The light emitted by the irradiation lamp 300 can be irradiated to the lesion area along the irradiation path, which not only can achieve stable irradiation of the lesion with good irradiation effect, but also ensure that the light emitted by the irradiation lamp will not directly shine outward into the doctor's eyes, thereby protecting the eyes.

[0056] It should be noted that, in this embodiment, the lighting lamp 300 is annular, and the expansion portion 110 and the matching portion 210 respectively pass through the through holes of the annular lighting lamp 300, so that the lighting lamp 300 irradiates the lesion along the radial direction of the expansion portion 110 and the matching portion 210 to improve the lighting effect.

[0057] like Figure 1 and Figure 3 As shown, the above drawings respectively show the situations where 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 the actual operating window size of the anal dilator needs to be increased or decreased, the matching member 200 is rotated relative to the anal dilator 100 around the axial direction to adaptively adjust the rotation angle of the anal dilator 100 and the matching member 200 around the axial direction, which is not specifically limited in this embodiment.

[0058] Specifically, if Figures 4 to 8 As shown, the illuminating lamp 300 is located between the inner surface of the fixing part 120 and the inner surface of the limiting part 220, the inner surface of the fixing part 120 includes a facing area and a misaligned area, the facing area is arranged facing the illuminating lamp 300 in the axial direction, and the misaligned area is arranged misaligned with the illuminating lamp 300 in the axial direction, the first reflection area includes the misaligned area and the outer surface of the fixing part 120, and the second reflection area includes the inner surface of the limiting part 220 and the outer surface of the limiting part 220. By arranging the illuminating lamp 300 between the inner surface of the fixing part 120 and the inner surface of the limiting part 220, the inner surface of the fixing part 120 is divided into the facing area facing the illuminating lamp 300 in the axial direction and the misaligned area misaligned in the axial direction, the misaligned area and the outer surface of the fixing part 120 form the first reflection area, and the outer surface and the inner surface of the limiting part 220 form the second reflection area, so that the light emitted by the illuminating lamp 300 can only enter the irradiation path along the facing area and irradiate on 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 frosting. After the corresponding areas of the fixing portion 120 and the limiting portion 220 are frosted, the corresponding areas cannot allow light to pass through the frosted layer to propagate to the outside, thereby preventing the light emitted by the illuminating lamp 300 from directly irradiating the eyes, and because the anal dilator 100 and the matching member 200 are both made of transparent materials, the light cannot pass through the frosted layer but can be reflected along the frosted layer, so as to achieve the effect of irradiating the lesion along the reflection path.

[0060] In addition, in other embodiments, a reflective film may be attached to the surfaces corresponding to the first reflective area and the second reflective area so that the reflective surface of the reflective film forms an irradiation path. When the light of the illuminating lamp 300 is irradiated on the reflective surface, the light can be reflected to irradiate the lesion.

[0061] As an optional solution, the radial dimension of the expansion portion 110 gradually decreases while extending axially from an end close to the fixing portion 120 toward a direction away from the fixing portion 120, and the radial dimension of the matching portion 210 gradually decreases while extending axially from an end close to the limiting portion 220 toward a direction away from the limiting portion 220, so that both the expansion portion 110 and the matching portion 210 are cone-shaped, which can facilitate the doctor to observe the lesions located outside the side walls of the cone-shaped 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 lesions.

[0062] In an optional solution, a threading hole 121 is provided on the fixing portion 120. When the expansion portion 110 is inserted into the anus, in order to prevent the expansion portion 110 from being separated from the anus, a surgical thread is sequentially passed through the threading hole 121 and surrounding tissues to prevent the expansion portion 110 from being separated from the anus.

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

[0064] To further prevent the expansion portion 110 from falling out of the anus, a threaded protrusion 112 is provided at one end of the expansion portion 110 close to the fixing portion 120. The threaded protrusion 112 is axially arranged around the circumference of the expansion portion 110. The threaded protrusion 112 is used to increase the friction between the expansion portion 110 and the anus, thereby preventing the expansion portion 110 from falling out of the anus.

[0065] like Figure 7 and Fig. 9As shown, the inner cavity wall of the expansion part 110 close to the matching part 210 is provided with a radially recessed positioning groove 113, the positioning groove 113 forms a closed ring around the axial direction, and the end of the matching part 210 away from the limiting part 220 along the axial direction is provided with a radially extending positioning protrusion 212, the positioning protrusion 212 is engaged with the positioning groove 113 along the axial direction, and the positioning protrusion 212 can rotate along the positioning groove 113. By providing the positioning groove 113 extending around the axial direction on the inner cavity wall of the expansion part 110 close to the matching part 210, so that the positioning groove 113 forms a closed ring, and providing the positioning protrusion 212 extending radially outward at one end of the matching part 210 away from the limiting part 220 along the axial direction, the positioning protrusion 212 is engaged with the positioning groove 113 together and rotates along the positioning groove 113, so that the effect of the anal expander 100 and the matching part 200 being engaged and fixed along the axial direction and the anal expander 100 rotating relative to the matching part 200 around the axial direction is achieved, the structure is simple and the structural strength is high.

[0066] During the assembly process of the anal expander 100 and the mating member 200, the positioning protrusion 212 and the positioning groove 113 need to be clamped together in the axial direction. In this process, the positioning protrusion 212 will drive the mating portion 210 to deform in the radial direction. In order to facilitate the clamping of the positioning protrusion 212 and the positioning groove 113, a deformation groove 214 is provided at one end of the mating portion 210 away from the limiting portion 220 in the axial direction. The deformation groove 214 is recessed in the axial direction close to the limiting portion 220, and the deformation groove 214 can provide a deformation space for the deformation of the mating portion 210. When the positioning protrusion 212 drives the mating portion 210 to deform in the radial direction, the mating portion 210 can compress the space of the deformation groove 214 to provide a deformation space for the deformation of the mating portion 210, thereby preventing the mating portion 210 from breaking during the deformation process and improving the protection of the mating portion 210.

[0067] In addition, at least two positioning protrusions 212 and at least two deformation grooves 214 are provided on the matching portion 210, at least two positioning protrusions 212 are provided on the matching portion 210 at intervals around the axial direction, at least two deformation grooves 214 are provided on the matching portion 210 at intervals around the axial direction, and a deformation groove 214 is provided between two adjacent positioning protrusions 212. By providing at least two positioning protrusions 212 and at least two deformation grooves 214 at intervals around the axial direction on the matching portion 210, a deformation groove 214 is provided between two adjacent positioning protrusions 212, which can not only realize that at least two positioning protrusions 212 are simultaneously engaged and slidably connected with the positioning groove 113, but also can further improve the protection of the matching portion 210. It should be noted that in this embodiment, three positioning protrusions 212 and three deformation grooves 214 are provided on the matching portion 210 at intervals around the axial direction. In other embodiments, the specific number of the positioning protrusions 212 and the deformation grooves 214 can also be adjusted according to actual needs, and this embodiment does not specifically limit it.

[0068] As an alternative, Fig.10 As shown, the surface of the matching portion 210 is provided with axially extending scale lines 213. By providing the axially extending scale lines 213 on the surface of the matching portion 210, not only the insertion depth of the expansion portion 110 can be quickly determined, but also the depth of the lesion can be quickly determined, which is convenient for subsequent treatment of the lesion.

[0069] Combination Fig.11 The specific structure of the illuminating lamp 300 is described. The illuminating lamp 300 includes a bulb structure 310, a first housing 320 and a second housing 330, wherein the first housing 320 and the second housing 330 are buckled and fixed together in the axial direction to form a receiving space, and the bulb structure 310 is received in the receiving space, and the first housing 320 is located at one end of the second housing 330 close to the expansion part 110 in the axial direction, and the first housing 320 is made of a transparent material. By providing the first housing 320 and the second housing 330 that are buckled and fixed together in the axial direction, a receiving space is formed between the first housing 320 and the second housing 330, and the bulb structure 310 is received in the receiving space, so that the bulb structure 310 is safely received and the protection of the bulb structure 310 is improved. By making the first housing 320 located at one end of the second housing 330 close to the expansion part 110 in the axial direction, and making the first housing 320 made of a transparent material, it is convenient for the light emitted by the bulb structure 310 to pass through the first housing 320 and enter the irradiation path. It should be noted that, in this embodiment, the second housing 330 is made of a transparent material, and the surface of the second housing 330 is frosted. When the light emitted by the bulb structure 310 is irradiated on the frosted surface of the second housing 330, the frosted surface can reduce the refraction of the light through the second housing 330 and increase the reflection of the light relative to the second housing 330, which can not only prevent the light from passing through the second housing 330 and directly hit the eyes, but also make the light along the reflected light of the second housing 330 shine on the lesion, further improving the lighting effect on the lesion. In other embodiments, the second housing 330 can also be made of a non-transparent material to enhance the reflection of the light on the second housing 330 and weaken the refraction of the light on the second housing 330, which is not specifically limited in this embodiment. In addition, the bulb structure 310 includes structures such as a bulb and a circuit board in the prior art, which will not be described in detail here to ensure simplicity.

[0070] In one alternative, if Fig.12 and Fig.13As shown, the anal dilator also includes 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 to the bulb structure 310 in the illuminating lamp 300, and the other of the two is connected to the power supply 600, and 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 to transmit power. By using the adapter plug 400 and the adapter socket 500 to be connected to the bulb structure 310 and the power supply 600 respectively, and by using the docking of the adapter plug 400 and the adapter socket 500, the effect of power transmission from the power supply 600 to the bulb structure 310 is achieved, so as to achieve continuous light emission of the bulb structure 310 and meet the continuous lighting requirements of the illuminating lamp 300. It should be noted that in this embodiment, the adapter plug 400 is connected to the bulb structure 310, and the adapter socket 500 is connected to the power supply 600.
