[0046] SUMMARY Figures 1-6 As shown, according to one embodiment of the present application, an ophthalmic surgery fluid collection device 1 is provided. The ophthalmic surgery fluid collection device 1 includes a box body 11 having a receiving cavity configured to receive waste fluid generated during surgery, the box body 11 having an opening portion in communication with the receiving cavity;

[0047] The feature identification block 12 is disposed on the box body 11, and the feature identification block 12 is located at the opening portion;

[0048] Optionally, a first cover plate 13 can be included, which is provided with a first matching portion and can be detachably covered on the opening portion of the box body 11, and the first matching portion corresponds to the feature recognition block 12 and exposes the feature recognition block 12, so that the feature recognition block 12 can be inducted by an external detection device;

[0049] Optionally, a second cover plate 14 can be included, which is provided with a second matching portion and can be detachably covered on the opening portion of the box body 11, and the second matching portion corresponds to the feature recognition block 12 and shields the feature recognition block 12, so that the feature recognition block 12 cannot be inducted by an external detection device;

[0050] The first cover plate 13 and the second cover plate 14 are connected to the box body 11 in an alternative manner.

[0051] The ophthalmic surgery fluid collection device 1 provided in the embodiments of the present application is used to guide and store the waste liquid generated by the flushing and suction operations in the accommodating cavity of the box body 11 in the ophthalmic surgery; since the ophthalmic surgery is divided into anterior segment surgery and posterior segment surgery, it is necessary to set an identification feature on the ophthalmic surgery fluid collection device 1 to identify the type of surgery corresponding to the ophthalmic surgery fluid collection device 1 for the surgery console. Specifically, the surgery console includes a detection device for detecting the identification feature. For example, the surgery console can be a phacoemulsification machine.

[0052] In the ophthalmic surgery fluid collection device 1 provided in the embodiments of the present application, the feature recognition block 12 as the identification feature is arranged at the opening portion of the box body 11, and when the first cover plate 13 corresponding to the first surgery type is installed on the opening portion of the box body 11, the first matching portion of the first cover plate 13 exposes the feature recognition block 12, so that the detection device of the surgery console can induct the presence of the feature recognition block 12, thereby determining that the surgery type is the first surgery type.

[0053] When the second cover plate 14 corresponding to the second surgery type is installed on the opening portion of the box body 11, the second matching portion of the second cover plate 14 shields the feature recognition block 12, so that the detection device of the surgery console cannot induct the presence of the feature recognition block 12, thereby determining that the surgery type is the second surgery type.

[0054] The significance of determining the surgery type is that the surgery console will enable the surgery function corresponding to the surgery type, and the surgery function not corresponding to the surgery type is disabled, thereby improving the safety of the surgery process.

[0055] In an optional example, for example, the first cover plate 13 corresponds to the first surgical type of posterior segment surgery; the second cover plate 14 corresponds to the second surgical type of anterior segment surgery. In other embodiments, other corresponding forms can also be provided.

[0056] For the ophthalmic surgery fluid collection device 1 provided by the embodiments of the present application, since the feature recognition block 12 is arranged on the box body 11, the box body 11 and the different cover plates cooperate to produce different matching effects on the feature recognition block 12, so that different identification 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 12, so that the type judgment algorithm of the cover plate is very simple, and a relatively complex judgment method is not needed.

[0057] In summary, by using the ophthalmic surgery fluid collection device 1 provided by the embodiments of the present application, the production difficulty of the cover plate can be reduced, and the type judgment algorithm of the cover plate is simplified, thereby helping to reduce the production cost.

[0058] Optionally, the first cover plate 13 / second cover plate 14 is assembled with the box body 11 by buckling, so as to facilitate replacement of the cover plate according to the surgical type.

[0059] Referring to Figure 5 In an embodiment, the first matching part is a first notch structure 130 opened in the side of the first cover plate 13.

[0060] When the first cover plate 13 is connected with the box body 11, the feature recognition block 12 is located at the first notch structure 130.

[0061] In this specific example, when the first cover plate 13 is connected with the box body 11, the first notch structure 130 opened in the side of the first cover plate 13 forms an avoiding effect on the feature recognition block 12, so as to ensure that the feature recognition block 12 can be exposed to be sensed by the detection device.

[0062] Referring to Figure 6 In an embodiment, the second matching part includes a second notch structure 140 and a shielding plate 15, the second notch structure 140 is opened in 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.

[0063] When the second cover plate 14 is connected with the box body 11, the feature recognition block 12 is located at the second notch structure 140, and the shielding plate 15 covers at least one side of the feature recognition block 12.

[0064] In the specific example, in the case that the second cover plate 14 is connected with the box body 11, the second notch structure 140 provided on the side of the second cover plate 14 forms an avoiding effect on the feature identification block 12, and meanwhile, the shielding plate 15 provided corresponding to the second notch structure 140 forms a shielding effect on the feature identification block 12, so as to ensure that the feature identification block 12 cannot be sensed by the detection device.

[0065] Specifically, for example, the box body 11 has a first side and a second side arranged oppositely, and in use, the ophthalmic surgical fluid collection device 1 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 surface of the feature identification block 12 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 side surfaces of the feature identification block 12, so as to further ensure that the feature identification block 12 cannot be sensed by the detection device in the case that the second cover plate 14 is installed.

[0066] Referring to Figure 4 In one embodiment, the cross-sectional shape of the feature identification block 12 is trapezoidal.

[0067] In the specific example, since the box body 11 and the feature identification block 12 are both made of transparent plastic material, the cross-sectional shape of the feature identification block 12 is arranged to be trapezoidal, so that the feature identification block 12 can form a prism effect, 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.

[0068] Specifically, in the case that the first cover plate 13 is connected with the box body 11, the feature identification block 12 is exposed, the photoelectric detector emits detection light, the detection light can be reflected by the two inclined sides of the trapezoid corresponding to the feature identification block 12, the photoelectric detector further receives the reflected light from the feature identification block 12, and then the surgical console determines that the corresponding surgical type is the first surgical type.

[0069] In the case that the second cover plate 14 is connected with the box body 11, the feature identification block 12 is shielded, at this time, the detection light emitted by the photoelectric detector cannot be reflected by the feature identification block 12, and the photoelectric detector cannot further receive the reflected light from the feature identification block 12, and then the surgical console determines that the corresponding surgical type is the second surgical type.

[0070] Therefore, in the ophthalmic surgical fluid collection device 1 provided in the embodiment 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 there is reflected light needs to be simply judged, so as to identify the surgical type, and the judgment algorithm is simple and clear.

[0071] Of course, in the case where the feature identification block 12 is exposed, the type of the fluid collection device can also be distinguished in more detail by changing the material, size, and other features of the feature identification block 12.

[0072] Referring to Figure 4 In one embodiment, the cross-sectional shape of the feature identification block 12 is isosceles trapezoidal.

[0073] In this specific example, the cross-sectional shape of the feature identification block 12 is isosceles trapezoidal, so that the two oblique sides of the trapezoid are completely the same, thereby providing better reflection of the detection light in the case where the first cover plate 13 is connected to the box body 11 and the feature identification block 12 is exposed.

[0074] Referring to Figure 4 In one embodiment, the cross-section of the feature identification block 12 includes a first bottom side 121, a second bottom side 122, a first oblique side 123, and a second oblique side 124, and the length of the first bottom side 121 is greater than the length of the second bottom side 122.

[0075] The angle between the first oblique side 123 and the first bottom side 121 is greater than or equal to 5° and less than or equal to 85°.

[0076] The angle between the second oblique side 124 and the first bottom side 121 is greater than or equal to 5° and less than or equal to 85°.

[0077] In this specific example, if the angle between the first / second oblique side 123 / 124 and the first bottom side 121 is less than 5°, the first / second oblique side 123 / 124 is too inclined to the horizontal; if the angle between the first / second oblique side 123 / 124 and the first bottom side 121 is greater than 85°, the first / second oblique side 123 / 124 is too inclined to the vertical; both of these cases are not conducive to the reflection of the detection light by the feature identification block 12.

[0078] Referring to Figure 4 In one embodiment, the thickness of the feature identification block 12 is greater than or equal to 0.5 mm.

[0079] If the thickness of the feature identification block 12 is less than 0.5 mm, the lengths of the first and second oblique sides 123 and 124 are too short, which is not conducive to the reflection of the detection light by the feature identification block 12; therefore, in this specific example, the thickness of the feature identification block 12 is greater than or equal to 0.5 mm.

[0080] In one embodiment, the box body 11 and the feature identification block 12 are integrally formed.

[0081] In the specific example, the feature identification block 12 is integrally formed with the box body 11 during the manufacturing of the box body 11, so that the subsequent process of connecting the feature identification block 12 with the box body 11 is omitted, thereby saving the process flow and avoiding the situation that the box body 11 and the feature identification block 12 are not tightly connected or are loose.

[0082] Referring to Figure 1 In one embodiment, the ophthalmic surgery effusion device further comprises a bag body 16, which is in communication with the accommodating cavity of the box body 11.

[0083] In the specific example, the bag body 16 is connected to the box body 11, and the internal space of the bag body 16 is in communication with the accommodating cavity of the box body 11 through the pipeline, so that the space for storing waste liquid of the ophthalmic surgery effusion device 1 can be effectively increased, thereby improving the use efficiency of the ophthalmic surgery effusion device 1.

[0084] Optionally, the bag body 16 can be connected to the side wall of the box body 11 through the pipeline.

[0085] Referring to Figure 5 In one embodiment, the first cover plate 13 comprises a suction pipe 131, an adapter cavity 132, a first pipeline 133, a second pipeline 134, and a flushing pipe 135.

[0086] 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 of the box body 11.

[0087] One end of the first pipeline 133 is in communication with the adapter cavity 132, and the other end of the first pipeline 133 is connected to the first surgical handpiece.

[0088] One end of the second pipeline 134 is in communication with the adapter cavity 132, and the other end of the second pipeline 134 is connected to the second surgical handpiece.

[0089] 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 the flushing source.

[0090] In the specific example, the suction pipe 131 contained in the first cover plate 13 is used for sucking waste liquid into the accommodating cavity of the box body 11; the suction pipe 131 is connected to the first pipeline 133 and the second pipeline 134 through the adapter cavity 132, wherein the first pipeline 133 is connected to the first surgical handpiece, and the second pipeline 134 is connected to the second surgical handpiece, so that in use, appropriate surgical handpieces and pipelines corresponding thereto 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 pipeline 133 and / or the second pipeline 134 when needed.

[0091] The irrigation pipe 135 is connected to the irrigation inlet pipe 1391 and the irrigation outlet pipe 1392 through the irrigation adapter cavity 138. The irrigation inlet pipe 1391 is connected to an irrigation source during an ophthalmic surgery, and the irrigation outlet pipe 1392 transmits irrigation fluid to an ophthalmic surgical instrument.

[0092] Referring to Figure 5 As shown in the drawings, 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 pipe 133 and the second pipe 134 through the adapter cavity 132.

[0093] In this specific example, the first backflow capsule 136 and the second backflow capsule 137 are provided for the purpose of clearing blockages; 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 the purpose of normal backflow, thereby improving the use reliability of the ophthalmic surgery fluid collection device 1.

[0094] The pipe arrangement included in the second cover plate 14 is similar to that of the first cover plate 13, and the present application will not be described again.

[0095] Referring to Figure 3 As shown in the drawings, in one embodiment, the ophthalmic surgery fluid collection device 1 further comprises a liquid level indicator 17, which is a protruding block provided on the inner side wall of the box body 11 and protrudes towards the accommodating cavity of the box body 11. The cross-sectional shape of the protruding block is trapezoidal, and the material of the protruding block is the same as that of the box body 11, which is transparent plastic material. Therefore, the cross-sectional shape of the protruding block is set to be trapezoidal, so that the liquid level indicator 17 can function as a prism; and in combination with a photoelectric detector on the surgical console, the detection of the liquid surface is realized. The photoelectric detector is a one-dimensional, vertically arranged array, and the liquid level indicator 17 works as a prism; when the detection light emitted by the photoelectric detector intersects the interface between the two media at an angle of 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 in 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 17 is air and the second side is liquid or air, when the detection light emitted by the photoelectric detector enters the liquid level indicator 17 at an angle nearly perpendicular to the side wall of the box body 11, the detection light undergoes two reflections at the interface between the two sloping sides of the trapezoidal shape and the substance on the second side, and is received by the photoelectric detector. When the second side of the liquid level indicator 17 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.

[0096] Optionally, the liquid level indicator 17 is arranged at a position corresponding to the position where the feature recognition block 12 is arranged, so that the same photoelectric detector can be used to sense and detect both of them.

[0097] The above embodiments mainly describe the differences between the embodiments, and the different optimization features between the embodiments can be combined to form a better embodiment without contradiction. For the sake of brevity, the details are not repeated here.

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.
