In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Medical staff uses the anoscope to inspect the anus among the prior art, generally has two kinds of solutions:

one is that the medical staff holds a hollow straight barrel-shaped anoscope with one hand and holds an illuminating tool (such as a flashlight) with the other hand, the illuminating tool is aligned to the anus along the anoscope body to provide illumination for the anus, at the moment, although the illumination light can be directly irradiated into the anus, the two hands of the medical staff are occupied, and the affected part of the intestinal tract in the anus cannot be treated; moreover, because the sight lines of the anoscope, the illuminating tool and the medical staff are basically in a straight line, the illuminating tool can influence the visual field of the medical staff.

Another is to arrange a light source beside the outer sleeve, which shines obliquely towards the outer sleeve, in order to expect that a small amount of light shines into the anus by reflecting or diffusely reflecting the light at the inner wall of the outer sleeve body. When the portable medical treatment device is used, medical staff open the light source, hold the light source (such as a flashlight) obliquely fixed with the wall of the outer sleeve with one hand, and treat the affected part of the intestinal tract in the anus with the other hand. In this case, although the medical staff can obtain a good visual field, the direct illumination light cannot be obtained inside the anus, and thus sufficient illumination cannot be obtained inside the anus.

The inventor wishes to provide an anoscope that allows medical personnel to treat the affected area while providing sufficient illumination and a good field of view. In addition, in order to prevent cross infection, the anoscope should be used as a disposable medical device, which needs to meet the above requirements and achieve the purpose of reducing the cost.

In order to solve the problems and at the same time, the inventor provides an anoscope through a large amount of experiments, and under the premise of hardly increasing the cost, the anoscope can enable medical staff to obtain sufficient illumination and good visual field and treat the affected part at the same time.

The concave pit 303 is an injection molding feed port, and is designed to be concave so as to prevent sharp contact with a human body, and the design can ensure that the outer surface of the inner sleeve 300 is smooth as a whole.

Fig. 5 is a schematic side view of the inner sleeve 300 of the anoscope 100 according to an embodiment of the present invention. As shown in fig. 5, the proximal end of the inner sleeve body 301 is provided with a circumferentially undulating grip ring 304.

Fig. 6 is a schematic perspective view illustrating a structure of a connection seat 400 of the anoscope 100 according to an embodiment of the present invention.

As shown in fig. 6, the coupling socket 400 includes a square head 410 and a round head 420. The square head part 410 and the round head part 420 are communicated and both arranged in a hollow way. The upper part of the inner cavity of the square head part 410 is provided with a stop block 4101, any corner of the inner cavity is provided with two clamping strips 4102 extending longitudinally for clamping the corners of the side plate 223 and the bottom plate 224 from two directions perpendicular to each other, and the far end face of the corner between the two clamping strips 4102 is provided with an inward-concave chamfer 4103. The lower part of the inner cavity of the square head part 410 is provided with a second engaging block 4104.

The outer sleeve handle 220 and the connecting seat 400 are connected through clamping of the side plate 223 and the bottom plate 224 which circumscribe the cavity 222 and the inner cavity of the square head 410.

The square head portion 410 is adapted to be removably coupled to the circumscribing cavity 222. When connected, the two side plates 223 and the bottom plate 224 enclose a planar rectangle with an open top. The corners of the flat rectangle are accessible to the interior cavity of the square head 410 due to the provision of the concave chamfer 4103. After the proximal end of the external connection cavity 222 enters the inner cavity of the square head 410, each corner of the plane rectangle surrounded by the proximal end face of the external connection cavity 222 of the side plate 223 and the bottom plate 224 is abutted to the two clamping strips 4102, which is beneficial to reducing friction force, so that the side plate 223 and the bottom plate 224 of the external connection cavity 222 are easy to slide into the inner cavity of the square head 410 along the clamping strips 4102 until the stop block 4101 abuts against the side plate 223 at the distal end side of the external connection cavity 222, and at this time, the second clamping block 4104 is clamped with the first clamping block 226.

When the anoscope 100 of the present invention is used by a medical professional, the connecting base 400 is connected to the outer lumen 222 of the outer sleeve 200 in the manner described above, and a light source (e.g., a flashlight) is connected to the inside of the rounded end 420 of the connecting base 400. The practitioner now holds outer sleeve handle 220 in one hand and uses the thumb of that hand to abut (or hold in the other hand) handle ring 304 of inner sleeve 300, and the nested outer and inner sleeves 200, 300 are simultaneously advanced into the anus. Inner sleeve head 302 extends out of distal opening 211 of outer sleeve 200 when inner sleeve 300 is nested with outer sleeve 200. Since the inner sleeve head 302 is conical and the outside diameter of the inner sleeve 301 is substantially the same as the inside diameter of the outer sleeve 210, the distal end of the anoscope 100 is conical overall, which clearly facilitates the entry of the anoscope 100 into the anus.

After the anoscope 100 enters the anus, medical personnel can observe the intestinal tract through the outer sleeve 200 and the inner sleeve 300 because all parts of the outer sleeve 200 and the inner sleeve 300 are transparent. At this time, since the plurality of light guide plates 221 constituting the light guide plate assembly are also transparent, when the light source irradiates the light guide plates 221 from the proximal side of the light guide plates 221, light rays extend along the light guide plates 221, and reach the joints of the light guide plates 221 and the outer sleeve body 210, and a part of the light rays pass through the lower cylinder wall of the outer sleeve body 210 and are emitted to the upper cylinder wall of the outer sleeve body 210; another portion of the light rays will extend along the lower wall of outer sleeve body 210 toward the distal end of outer sleeve body 210, according to the principles of refraction and reflection of light, and ultimately illuminate the distal end of outer sleeve 200. That is, the transparent light guide plate 221 and the cylindrical wall of the transparent outer sleeve 210 form a light guide for guiding the light direction, and an illumination effect equivalent to direct light directly irradiating the distal end of the outer sleeve 200 is generated on the distal end side of the outer sleeve 210.

After the anoscope 100 is operated to reach a proper position, the medical staff uses the other hand to draw out the inner sleeve 300 and place the affected part at the open slot 212. Now with sufficient brightness at the distal end of outer sleeve 200, the medical professional can manipulate the medical device with the other hand to treat the affected area.

During the above examination or treatment procedure, there may be bodily fluids flowing into outer sleeve body 210 from distal opening 211 or open slot 212 of outer sleeve 200 and out of outer sleeve body 210 along the inner wall of outer sleeve body 210 and the inner wall of flare 213. The upper cover plate 225 may prevent body fluid from flowing out of the inner wall of the bell mouth 213 and to the outer sleeve handle 220 from affecting the light guiding properties of the light guide assembly. In addition, since the upper cover plate 225 extends to the side plate 223 at the distal side of the external connection cavity 222, when the body fluid flows to the side plate 223 at the distal side of the external connection cavity 222 along the upper cover plate 225, the body fluid flows to the bottom of the external connection cavity 222 along the proximal side of the side plate 223 at the distal side of the external connection cavity 222 due to the opening at the upper part of the external connection cavity 222, and finally flows out, so that it can be ensured that the light source connected to the connection socket 400 is not polluted by the body fluid as long as it does not contact the bottom of the external connection cavity 222. Unlike the design concepts provided by the present invention, the general concept is to prevent the body fluid from entering the junction between the external cavity 222 and the connection seat 400 without considering providing corresponding guidance for the body fluid so that it does not contaminate the light source. If the above general concept is followed, waterproof sealing is considered, which obviously requires a great cost to solve the sealing problem at the junction of the external connection cavity 222 and the connection socket 400. Therefore, the utility model provides a structural design concept is more ingenious. In various embodiments of the present invention, the junction between the connecting socket 400 and the external cavity 222 is not sealed, and it is based on such considerations.

The utility model provides an anoscope 100, simple structure, with low costs. The transparent light guide plate 221 and the wall of the transparent outer sleeve 210 are used as light guides for guiding light rays, so that medical staff can obtain sufficient illumination; therefore, the light source does not need to be directly emitted, the sight of medical staff is not blocked, and a good visual field is obtained; since the outer sleeve 200 and the light source can be held with only one hand, the other hand is freed to be used for treating the affected part.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing is a more detailed description of the invention, and the specific embodiments thereof are not to be considered as limiting. Various changes in form and detail, including simple deductions or substitutions, may be made by those skilled in the art without departing from the spirit and scope of the invention.
