[0047] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0048] It should be noted that like reference numerals and letters refer to like items throughout the several views of the drawings, and that discussion of one item in a drawing does not require further discussion of that item in subsequent drawings.

[0049] Reference Signs List: Figures 1-6As shown, according to one embodiment of the present application, an ophthalmic surgery fluid collection device is provided. The ophthalmic surgery fluid collection device comprises a device body 1 having a receiving cavity configured to receive waste fluid generated during surgery, the device body 1 having a side wall 110; and a liquid level indicator 12 disposed on the inner side of the side wall 110, the liquid level indicator 12 being protrudingly disposed towards the receiving cavity of the device body 1; the liquid level indicator 12 being configured to cooperate with an external detection device to detect the height of the liquid in the receiving cavity.

[0050] The ophthalmic surgery fluid collection device provided by the embodiments of the present application is used to guide and store waste fluid generated by operations such as flushing and suction during ophthalmic surgery into the receiving cavity of the device body 1; in order to grasp the liquid level height in the receiving cavity, the liquid level indicator 12 needs to be provided on the device body 1, which cooperates with the external detection device to detect the height of the liquid in the receiving cavity. For example, the liquid level indicator 12 functions as a prism, and the external detection device is a photoelectric detector; the specific detection principle will be explained in detail below.

[0051] In the ophthalmic surgery fluid collection device provided by the embodiments of the present application, the liquid level indicator 12 is protrudingly disposed towards the receiving cavity of the device body 1, that is, the liquid level indicator 12 is a protruding block disposed on the inner side of the side wall 110; therefore, when the ophthalmic surgery fluid collection device is manufactured, the mold used only needs to form a recessed area, compared with machining a protruding area on the mold, the mold structure used by the ophthalmic surgery fluid collection device is simpler and has lower cost, and therefore the production and manufacturing process of the ophthalmic surgery fluid collection device is more simplified and is conducive to saving production cost.

[0052] Referring to Figure 4 As shown, in one embodiment, the cross-sectional shape of the liquid level indicator 12 comprises a trapezoidal shape.

[0053] In this specific example, the liquid level indicator 12 is a protruding block arranged on the inner side wall of the device body 1, which protrudes towards the accommodating cavity of the device body 1. The cross-sectional shape of the protruding block comprises a trapezoid, and the material of the protruding block is the same as that of the device body 1, i.e., transparent plastic material. Therefore, the cross-sectional shape of the protruding block is set as a trapezoid, so that the liquid level indicator 12 can function as a prism; and in combination with the photoelectric detector on the surgical console, the detection of the liquid level can be realized. The photoelectric detector is a one-dimensional and vertically arranged array, and the liquid level indicator 12 functions as a prism; when the detection light emitted by the photoelectric detector intersects with the interface between the two media at an angle less than 90°, some of the detection light is reflected and some of the detection light is transmitted. The angle of the incident light and the change of the refractive index between the two media determine how much light is transmitted and how much light is reflected. In the case where the first side of the liquid level indicator 12 is air and the second side is liquid or air, when the detection light emitted by the photoelectric detector enters the liquid level indicator 12 at an angle nearly perpendicular to the side wall of the device body 1, the detection light is reflected twice at the interface between the two sloping sides of the trapezoid of the liquid level indicator 12 and the substance on the second side, and is received by the photoelectric detector. When the second side of the liquid level indicator 12 is waste liquid or air, respectively, the photoelectric detector will receive reflected light of different intensities, thereby realizing the judgment of the liquid level height.

[0054] Referring to Figure 4 In one embodiment, the cross-sectional shape of the liquid level indicator 12 comprises an isosceles trapezoid.

[0055] In this specific example, the cross-sectional shape of the liquid level indicator 12 comprises an isosceles trapezoid, so that the two sloping sides of the trapezoid are completely the same, thereby providing better reflection effect for the detection light emitted by the photoelectric detector.

[0056] Referring to Figure 4 In one embodiment, the cross-section of the liquid level indicator 12 comprises a first bottom side 121, a second bottom side 122, a first sloping side 123 and a second sloping side 124, and the length of the first bottom side 121 is greater than the length of the second bottom side 122.

[0057] The included angle between the first sloping side 123 and the first bottom side 121 is greater than or equal to 5° and less than or equal to 85°.

[0058] The included angle between the second sloping side 124 and the first bottom side 121 is greater than or equal to 5° and less than or equal to 85°.

[0059] If the angle between the first slanted edge 123 / second slanted edge 124 and the first bottom edge 121 is less than 5°, the first slanted edge 123 / second slanted edge 124 is too inclined to the horizontal; if the angle between the first slanted edge 123 / second slanted edge 124 and the first bottom edge 121 is greater than 85°, the first slanted edge 123 / second slanted edge 124 is too inclined to the vertical; in both cases, the liquid level indicator 12 is not conducive to reflecting the detection light. Therefore, in this specific example, the angle between the first slanted edge 123 and the first bottom edge 121 is set to be greater than or equal to 5° and less than or equal to 85°; the angle between the second slanted edge 124 and the first bottom edge 121 is also set to be greater than or equal to 5° and less than or equal to 85°

[0060] Referring to Figure 4 In one embodiment, the thickness of the liquid level indicator 12 is greater than or equal to 0.5 mm.

[0061] If the thickness of the liquid level indicator 12 is less than 0.5 mm, the length of the first slanted edge 123 and the second slanted edge 124 is too short, which is not conducive to the liquid level indicator 12 reflecting the detection light; therefore, in this specific example, the thickness of the liquid level indicator 12 is set to be greater than or equal to 0.5 mm.

[0062] Referring to Figure 1 , Figure 2 In one embodiment, the device body 1 includes a box body 11 having an opening portion communicating with the accommodating cavity, and a cover capable of being detachably covered on the opening portion of the box body 11, and the side wall 110 is formed on the box body 11.

[0063] Optionally, the box body 11 and the liquid level indicator 12 are integrally formed.

[0064] In this specific example, the liquid level indicator 12 is integrally formed at the same time when the box body 11 is manufactured, which saves the subsequent process of connecting the separate liquid level indicator and the box body, saves the process flow, and does not cause the box body 11 and the liquid level indicator 12 to be not tightly connected or to be loose.

[0065] Referring to Figure 2 , Figure 3 In one embodiment, the ophthalmic surgery effusion device further includes a feature recognition block 17, the feature recognition block 17 is arranged on the box body 11, and the feature recognition block 17 is located at the opening portion;

[0066] The cover includes a first cover plate 13 and a second cover plate 14. The first cover plate 13 is provided with a first matching part, and is detachably arranged on the opening of the box body 11. The first matching part corresponds to the feature identification block 17 and exposes the feature identification block 17.

[0067] The second cover plate 14 is provided with a second matching part, and is detachably arranged on the opening of the box body 11. The second matching part corresponds to the feature identification block 17 and covers the feature identification block 17.

[0068] The first cover plate 13 and the second cover plate 14 are selectively connected with the box body 11.

[0069] In this specific example, since ophthalmic surgery is divided into anterior segment surgery and posterior segment surgery, it is necessary to provide an identification feature on the ophthalmic surgery fluid collection device for the surgical console to identify the type of surgery corresponding to the ophthalmic surgery fluid collection device. Specifically, the surgical console includes a detection device for detecting the identification feature. For example, the surgical console can be a phacoemulsification machine.

[0070] In the ophthalmic surgery fluid collection device provided in the embodiments of the present application, the feature identification block 17 as the identification feature is arranged at the opening of the box body 11. After the first cover plate 13 corresponding to the first type of surgery is installed on the opening of the box body 11, the first matching part of the first cover plate 13 exposes the feature identification block 17, so that the detection device of the surgical console can sense the presence of the feature identification block 17, thereby determining that the type of surgery is the first type of surgery.

[0071] After the second cover plate 14 corresponding to the second type of surgery is installed on the opening of the box body 11, the second matching part of the second cover plate 14 covers the feature identification block 17, so that the detection device of the surgical console cannot sense the presence of the feature identification block 17, thereby determining that the type of surgery is the second type of surgery.

[0072] The significance of determining the type of surgery is that the surgical console will enable the surgical functions corresponding to the type of surgery, and the surgical functions not corresponding to the type of surgery will be disabled, thereby improving the safety of the surgical process.

[0073] In an optional example, for example, the first type of surgery corresponding to the first cover plate 13 is posterior segment surgery; the second type of surgery corresponding to the second cover plate 14 is anterior segment surgery. In other embodiments, other corresponding forms can also be provided.

[0074] According to the ophthalmic surgery fluid accumulation device provided in the embodiments of the present application, the feature recognition block 17 is arranged on the box body 11, and the box body 11 and different cover plates have different matching effects on the feature recognition block 17, so that different recognition features do not need to be specially arranged for each cover plate, and the structure of the cover plate is relatively simple; and when the type of the cover plate is judged by the detection device, it is only necessary to judge according to whether the detection device can sense the presence of the feature recognition block 17, so that the type judgment algorithm of the cover plate is very simple, and a relatively complex judgment method is not needed.

[0075] In summary, the ophthalmic surgery fluid accumulation device provided in the embodiments of the present application can reduce the production difficulty of the cover plate and simplify the type judgment algorithm of the cover plate, thereby helping to reduce the production cost.

[0076] Optionally, the first cover plate 13 / second cover plate 14 is assembled with the box body 11 through buckling, so as to facilitate replacement of the cover plate according to the type of surgery.

[0077] Referring to FIGS. 1-4, Figure 5 , Figure 6 In one embodiment, the first matching part is a first notch structure 130 arranged on the side of the first cover plate 13;

[0078] When the first cover plate 13 is connected with the box body 11, the feature recognition block 17 is located at the first notch structure 130;

[0079] The second matching part includes a second notch structure 140 and a shielding plate 15, the second notch structure 140 is arranged on the side of the second cover plate 14, the shielding plate 15 is connected with the side of the second cover plate 14, and the shielding plate 15 is arranged corresponding to the second notch structure 140;

[0080] When the second cover plate 14 is connected with the box body 11, the feature recognition block 17 is located at the second notch structure 140, and the shielding plate 15 covers at least one side of the feature recognition block 17.

[0081] In this specific example, when the first cover plate 13 is connected with the box body 11, the first notch structure 130 arranged on the side of the first cover plate 13 forms an avoiding effect on the feature recognition block 17, so as to ensure that the feature recognition block 17 can be exposed to be sensed by the detection device.

[0082] In the case that the second cover plate 14 is connected with the box body 11, the second notch structure 140 formed on the side of the second cover plate 14 has an avoiding effect on the feature identification block 17, and meanwhile, the shielding plate 15 arranged corresponding to the second notch structure 140 has a shielding effect on the feature identification block 17, so as to ensure that the feature identification block 17 cannot be sensed by the detection device.

[0083] Specifically, for example, the box body 11 has a first side and a second side arranged oppositely, and in use, the ophthalmic surgery fluid collection device is installed in a posture that the first side of the box body 11 faces the detection device, so that the shielding plate 15 at least shields the side of the feature identification block 17 corresponding to the first side of the box body 11. Of course, without affecting the convenience of installing the second cover plate 14, the shielding plate 15 can also be arranged to shield both sides of the feature identification block 17, so as to further ensure that the feature identification block 17 cannot be sensed by the detection device in the case that the second cover plate 14 is installed.

[0084] In an embodiment, the cross-sectional shape of the feature identification block 17 is trapezoidal.

[0085] In this specific example, since the box body 11 and the feature identification block 17 are both made of transparent plastic material, the cross-sectional shape of the feature identification block 17 is arranged as trapezoidal, so that the feature identification block 17 can form the effect of a prism, and the detection device is a photoelectric detector, so that the photoelectric detector and the prism cooperate with each other to determine the type of the cover plate.

[0086] Specifically, in the case that the first cover plate 13 is connected with the box body 11, the feature identification block 17 is exposed, the photoelectric detector emits detection light, the detection light can be reflected by the two inclined sides of the feature identification block 17 corresponding to the trapezoidal shape, the photoelectric detector further receives the reflected light from the feature identification block 17, and then the surgical console determines that the corresponding surgical type is the first surgical type.

[0087] In the case that the second cover plate 14 is connected with the box body 11, the feature identification block 17 is shielded, at this time, the detection light emitted by the photoelectric detector cannot be reflected by the feature identification block 17, and the photoelectric detector cannot further receive the reflected light from the feature identification block 17, and then the surgical console determines that the corresponding surgical type is the second surgical type.

[0088] Therefore, in the ophthalmic surgery fluid collection device provided in the embodiments of the present application, different identification features do not need to be specially arranged for the first cover plate 13 and the second cover plate 14, and it is also unnecessary to complexly judge the wavelength, intensity and other characteristics of different reflected light from different identification features; only whether the reflected light exists needs to be simply judged, so as to identify the surgical type, and the judgment algorithm is simple and clear.

[0089] Of course, in the case where the feature recognition block 17 is exposed, it is also possible to make more detailed distinctions between the types of the effusion device by changing the material, size, and other features of the feature recognition block 17.

[0090] Optionally, the liquid level indicator 12 is arranged at a position corresponding to the position where the feature recognition block 17 is arranged, so that the same photoelectric detector can be used to sense and detect both of them.

[0091] Referring to Figure 5 In one embodiment, the first cover plate 13 includes a suction pipe 131, an adapter cavity 132, a first pipe 133, a second pipe 134, and a flushing pipe 135.

[0092] One end of the suction pipe 131 is in communication with the adapter cavity 132, and the other end of the suction pipe 131 is in communication with the accommodating cavity.

[0093] One end of the first pipe 133 is in communication with the adapter cavity 132, and the other end of the first pipe 133 is connected to a first surgical handpiece.

[0094] One end of the second pipe 134 is in communication with the adapter cavity 132, and the other end of the second pipe 134 is connected to a second surgical handpiece.

[0095] One end of the flushing pipe 135 is in communication with the adapter cavity 132, and the other end of the flushing pipe 135 is connected to a flushing source.

[0096] In this specific example, the suction pipe 131 included in the first cover plate 13 is used for the suction of waste liquid into the accommodating cavity of the box body 11; the suction pipe 131 is connected to the first pipe 133 and the second pipe 134 through the adapter cavity 132, wherein the first pipe 133 is connected to the first surgical handpiece, and the second pipe 134 is connected to the second surgical handpiece, so that in use, the appropriate surgical handpiece and the corresponding pipe can be flexibly selected according to the surgical requirements; the flushing pipe 135 is connected to the flushing source to provide flushing liquid to the first pipe 133 and / or the second pipe 134 when needed.

[0097] The flushing pipe 135 is connected to the flushing inlet pipe 1391 and the flushing outlet pipe 1392 through the flushing adapter cavity 138. The flushing inlet pipe 1391 is connected to the flushing source during the ophthalmic surgery, and the flushing outlet pipe 1392 transmits the flushing fluid to the ophthalmic surgical instrument.

[0098] Referring to Figure 5As shown, in one embodiment, the first cover plate 13 further comprises a first backflow capsule 136 and a second backflow capsule 137, both of which are communicated to the first pipeline 133 and the second pipeline 134 through the adapter cavity 132.

[0099] In this specific example, the first backflow capsule 136 and the second backflow capsule 137 are arranged to be used for clearing blockage; and when one of the first backflow capsule 136 and the second backflow capsule 137 has poor resilience and affects the working effect, the other one can be used to achieve normal backflow, thereby improving the use reliability of the ophthalmic surgery effusion device.

[0100] The pipeline arrangement included in the second cover plate 14 is similar to that of the first cover plate 13, and thus will not be described herein.

[0101] Reference Figure 1 As shown, in one embodiment, the ophthalmic surgery effusion device further comprises a bag body 16, which is communicated to the accommodating cavity of the device body 1.

[0102] In this specific example, the bag body 16 is connected to the box body 11, and the internal space of the bag body 16 is communicated to the accommodating cavity of the box body 11 through the pipeline; in this way, the space for storing waste liquid of the ophthalmic surgery effusion device can be effectively increased, thereby improving the use efficiency of the ophthalmic surgery effusion device.

[0103] Optionally, the bag body 16 can be connected to the side wall of the box body 11 through the pipeline.

[0104] The above embodiments mainly describe the differences between the embodiments, and the different optimization features between the embodiments can be combined to form a more optimal embodiment as long as they are not contradictory. In view of the brevity of the writing, the details will not be described herein.

Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application.
