[0001] This application claims priority to U.S. Provisional Application No. 63 / 579,124, filed August 28, 2023, which is incorporated herein by reference in its entirety. Background Technology

[0002] During ophthalmic surgical procedures, fluids and / or other fluids (such as saline solution and / or air) are typically supplied to the patient's eye via one or more supply lines fluidly connected to the surgical console. To ensure sterility between surgical procedures, a new supply line is connected to the surgical console for each procedure and subsequently discarded after use. Summary of the Invention

[0003] This disclosure generally relates to devices for ophthalmic procedures, and more specifically to devices for delivering infusion gases. In some embodiments, a connector for a surgical console is provided. The connector includes: a proximal portion having a proximal port configured to be received by the surgical console; and a distal portion having a distal port. The connector also includes a conduit extending between the proximal and distal portions, the proximal port being in fluid communication with the distal port via the conduit, and the conduit having a flow axis extending along and substantially parallel to a flow direction between the proximal and distal ports. An annular flange is formed along an outer surface of the conduit and extends perpendicular to the flow axis from the outer surface of the conduit, the annular flange separating the proximal and distal portions. The proximal portion of the connector includes one or more light-blocking pillars extending from the proximal port. Each of the one or more light-blocking pillars extends parallel to the flow axis of the conduit and is configured to interact with the light tube of the surgical console when the proximal portion of the connector is connected to the surgical console.

[0004] In another embodiment, a receiver is provided for connecting a connector to a surgical console. The receiver includes a port located at a distal end of the receiver opposite to its proximal end. The port at the distal end of the receiver is sized and shaped to receive the connector, and the proximal end of the receiver is configured to connect to the surgical console. The receiver also includes: a conduit extending from the port at the distal end of the receiver through the receiver to the proximal end; and a pair of light-emitting apertures. The conduit has a flow axis extending along and substantially parallel to the flow direction through the port and the conduit. The light-emitting apertures are configured to receive extensions of light-emitting tubes passing through the conduit, the light-emitting tubes extending substantially perpendicular to the flow axis of the conduit.

[0005] In another embodiment, a connector assembly for a surgical console is provided. The assembly includes: a receiver, the size and shape of which are determined for reception by a receiver portion in the surgical console; and a connector, the size and shape of which are determined for insertion into the receiver. The receiver portion of the surgical console is in fluid communication with an infusion gas or a vacuum gas. The receiver includes a port disposed at a distal end of the receiver opposite to a proximal end of the receiver. The port at the distal end of the receiver is sized and shaped to receive the connector, and the proximal end of the receiver is configured to connect to the surgical console. The receiver also includes a receiver conduit extending from the port at the distal end of the receiver through the receiver to the proximal end. The receiver has a flow axis extending along and substantially parallel to a flow direction passing through the port and the receiver conduit. The receiver also includes a pair of light tube apertures configured to receive an extension of light tube passing through the receiver conduit, the light tube extending substantially perpendicular to the flow axis of the receiver.

[0006] The connector of the component includes: a proximal portion having a proximal port configured to be received by the surgical console; and a distal portion having a distal port. The connector also includes a connector conduit extending between the proximal and distal portions, the proximal port being in fluid communication with the distal port via the connector conduit, and the connector conduit having a flow axis extending along and parallel to the flow direction between the proximal and distal ports. An annular flange is formed along the outer surface of the connector conduit and extends perpendicular to the flow axis from the outer surface of the connector conduit, separating the proximal and distal portions. The proximal portion of the connector includes one or more light-blocking pillars extending from the proximal port. The one or more light-blocking pillars are configured to prevent the light tube from passing through the extension of the receiver conduit when the receiver is received by the surgical console and the proximal portion of the connector is inserted into and rotated in the receiver. When the receiver is received by the receiver portion of the surgical console and the connector is connected to the receiver, the proximal port of the connector is in fluid communication with the infusion or vacuum gas source.

[0019] For ease of understanding, the same reference numerals have been used where possible to refer to the same elements common to the figures. It is contemplated that elements and features of one embodiment can be advantageously combined in other embodiments without further description. Detailed Implementation

[0020] In the following description, details are illustrated by way of example to aid understanding of the disclosed subject matter. However, it will be clear to those skilled in the art that the disclosed embodiments are exemplary and not an exhaustive list of all possible embodiments. Therefore, it should be understood that references to the described examples are not intended to limit the scope of this disclosure. Those skilled in the art to which this disclosure pertains will generally be fully capable of conceiving any changes and further modifications to the described apparatus, instruments, and methods, as well as any further applications of the principles of this disclosure. In particular, it will be fully contemplated that features, components, and / or steps described for one embodiment can be combined with features, components, and / or steps described for other embodiments of this disclosure.

[0021] It should be noted that, as described herein, the distal end or distal portion of a component refers to the end or portion that is closer to the patient's body in a straight line during the use of the component. On the other hand, the proximal end or proximal portion of a component refers to the end or portion that is farther from the patient's body in a straight line (e.g., closer to the surgical console).

[0022] When the term "basically" is used, it can mean that the value can vary by ±10%, 5%, 2%, or 1%. For example, "basically parallel" or "basically perpendicular" means that the orientation of the two objects may vary by ±1 to 5 degrees.

[0023] To ensure patient safety and the efficient execution of a given ophthalmic surgical procedure, the fluid supply line must be correctly connected to the surgical console. Otherwise, inconsistent flow and pressure of the fluid through the supply line may negatively impact the procedure's execution. Incorrect connection of the supply line can also lead to accidental disconnection from the surgical console during the procedure, thereby interrupting fluid flow from the surgical console and posing increased safety risks to the patient. Therefore, what is needed in the art is an improved connector for connecting the fluid supply line to the surgical console.

[0024] This disclosure generally relates to port connector assemblies for connecting fluid supply lines used to deliver infusion gases during ophthalmic surgeries and procedures. The following description provides a connector assembly for removably but securely connecting a gas supply line to a supply port and / or other gas source on a surgical console. The connector assembly includes a connector configured to engage with a proximal end of the gas supply line, and a corresponding receiver configured to operatively engage with the surgical console and receive the connector. In some embodiments, the described connector assembly facilitates reduced direct manipulation of the gas supply line itself, as the user only needs to engage / manipulate the connector and receiver when connecting a new gas supply line. This helps maintain the sterility and integrity of the gas supply line and facilitates efficient connection and disconnection of the line to the surgical console before and after each procedure.

[0025] In some embodiments, the described connector assembly also facilitates a secure temporary locking between the connector and the corresponding receiver / port, and provides an indication to the surgical console when the connector and the corresponding receiver / port are locked. Therefore, the connector assembly can help surgeons confirm that the gas supply lines are correctly and securely connected before initiating surgery and prevent the connector from accidentally disconnecting from the corresponding receiver / port during surgery.

[0026] Figure 1 A perspective view of an exemplary surgical console 100 is shown, with which the connector assemblies described herein can be used in combination. The surgical console 100 is operatively and physically or wirelessly coupled to any number of user interfaces, including a foot pedal controller 102 and surgical tools 104 such as vitrectomy probes and other devices. The surgical console 100 provides one or more ports 106 for physically coupling the user interfaces to various components of the surgical console 100. For example, the surgical tool 104 may be fluidly coupled to a vacuum source via a supply line 108 connected to port 106 to enable aspiration of excised vitrectomy tissue from the patient's eye. However, the supply line 108 and port 106 may also represent other types of supply lines and / or ports for coupling with the surgical tool 104 as needed during a given surgical procedure.

[0027] Similarly, one or more other ports of the surgical console 100 can be used to connect the fluid infusion system to one or more infusion fluid sources (e.g., air / gas source, liquid perfluorocarbon source, silicone oil infusion (SOI) source, BSS (balanced salt solution) source, etc.) to enable fluid infusion into the eye during vitreous removal. Figure 1As shown, the exemplary fluid delivery system 110 includes a delivery line 112 that is fluidly connected at a three-way automatic valve assembly 118 to a gas supply line 114 and a liquid supply line 116, allowing different delivery fluids and / or components to flow selectively through the delivery line 112. The gas supply line 114 may be fluidly connected to a gas source via a port 106 of the surgical console 100. Conversely, the liquid supply line 116 may be fluidly connected to a liquid source via a port in a surgical cassette 123 used with the surgical console 100. In some other embodiments, the liquid supply line 116 may alternatively be connected directly to the liquid source and the surgical console 100 via another port 106 of the surgical console 100. Typically, the connection of each supply line to the surgical cassette 123 or the surgical console 100 is accomplished via a connector attached to the supply line and a corresponding receiver on the cassette or console. Such a connector and its corresponding receiver together may be referred to herein as a “connector assembly.” Figure 1 As shown, connector 122 is used to connect gas supply line 114 to the corresponding receiver 124 of port 106 of surgical console 100.

[0028] In operation, a user can control aspects or mechanisms of the surgical instrument 104 and / or the fluid infusion system 110 via actuation of the foot pedal controller 102. For example, a user can press down (e.g., depress) the foot pedal controller 102 to initiate and increase the flow rate of infusion fluid from the fluid source through the fluid infusion system 110 and into the patient's eye. Alternatively, reducing the pressure on the foot pedal controller 102 (e.g., lifting the user's foot) can reduce and eventually stop the flow of fluid through the fluid infusion system 110. Thus, in some embodiments, the flow rate of infusion fluid through the fluid infusion system 110 corresponds to the amount of pressure applied to the foot pedal controller 102. In other embodiments, the user can use the foot pedal controller 102 to select between fluid sources.

[0029] In some embodiments, the surgical console 100 further includes a display 120 for displaying information to a user (the display may also be combined with a touchscreen for receiving user input). Thus, the display 120 can display information about each user interface connected to the surgical console 100. For example, according to the fluid infusion system 110, the display 120 can show the user information related to infusion fluid parameters (e.g., infusion fluid flow rate and intraocular pressure) during its operation.

[0030] Figure 2A and Figure 2B A connector assembly 200 is shown, which can be implemented with the surgical console 100 for removably connecting the gas supply line 114 to a gas source. Figure 2A and Figure 2B As shown, connector assembly 200 typically includes connector 202 configured to removably engage with a corresponding receiver 204 (hereinafter referred to as "receiver 204"). Connector 202 and receiver 204 are Figure 1 Examples of connector 122 and receiver 124 are shown.

[0031] Typically, connector 202 is removably connected to receiver 204 at one end and removably connected to gas supply line 114 at the opposite end. Meanwhile, receiver 204 can be fixedly integrated with surgical console 100 at port 106 for receiving connector 202, or receiver 204 can be removably connected to surgical console 100 at port 106. When connector 202 is connected to receiver 204, as... Figure 2A As shown, connector assembly 200 provides a fluid-sealed conduit for fluidly connecting gas supply line 114 to port 106. During use, the conduit extending through connector assembly 200 allows gas (such as low-pressure air) to flow bidirectionally between gas supply line 114 and a gas source connected to surgical console 100. Connector 202 can also be disconnected from receiver 204, as... Figure 2B As shown, the gas supply line 114 is disconnected from the corresponding receiver 204, and thus from port 106 of the surgical console 100.

[0032] Now go to Figures 3A to 3E , Figure 3A and Figure 3B A perspective view of an exemplary connector 202 according to certain embodiments is shown; Figure 3C A cross-sectional view of connector 202 according to certain embodiments is shown; Figure 3D An enlarged perspective view of a portion of connector 202 according to certain embodiments is shown; and Figures 3E to 3F An end view of connector 202 according to certain embodiments is shown. Therefore, for clarity, this document will... Figures 3A to 3E Describe them together.

[0033] Connector 202 typically includes a distal portion 302 having a distal port 304, which is disposed opposite to a proximal portion 306 having a proximal port 308. The distal port 304 is connected via a connector conduit 310 extending through connector 202. Figure 3C(Shown in the image) It is in fluid communication with the proximal port 308. An annular flange 312 having a distal side 313 and a proximal side 315 is disposed between the distal portion 302 and the proximal portion 306. The annular flange 312 extends radially from the outer surface 317 of the connector conduit 310 in a manner substantially perpendicular to the longitudinal flow axis of the connector conduit 310. That is, the principal plane of the annular flange 312 is substantially perpendicular to the longitudinal flow axis of the connector conduit 310. The annular flange 312 generally separates the distal portion 302 and the proximal portion 306 of the connector 202, wherein the distal side 313 of the annular flange 312 faces the distal portion 302 of the connector 202 and the proximal side 315 faces the proximal portion 306. When connector 202 is in use, the annular flange 312 provides protection against user contact with non-sterile surfaces of the surgical console 100 when manipulating and operating the distal portion 302 to connect the proximal portion 306 of connector 202 to the port 106 of the surgical console 100 or the receiver 204 disposed therein. Connector 202 can be made of any material commonly used for such connectors and suitable for ophthalmic surgical setups. For example, connector 202 can be formed from thermoplastic polymers and other polymeric materials, lightweight aluminum, anodized aluminum, stainless steel and other metal alloys, or other suitable materials.

[0034] like Figure 3A As shown, the distal portion 302 of connector 202 also includes a first fin 314, a second fin 316, a conduit member 318, and a barbed collar 320. The first fin 314 and the second fin 316 extend from the outer surface of the conduit member 318. The first fin 314 and the second fin 316 also extend distally from the annular flange 312, such that the first fin 314 and the second fin 316 are oriented perpendicular to the principal plane of the annular flange 312. During use, the first fin 314 and the second fin 316 allow a user to grip and manipulate (e.g., rotate / turn) connector 202 to engage connector 202. The barbed collar 320 is disposed between the distal port 304 and the distal end 321 of the conduit member 318. In some embodiments, the first fin 314, the second fin 316, the conduit member 318, and the barbed collar 320 may be formed, for example, by injection molding as a single integral component of connector 202. In some embodiments, the first fin 314, the second fin 316, the conduit member 318, and the barbed collar 320 may each be a separate part of the connector 202, which are assembled together. In this embodiment, the barbed collar 320 may help retain the conduit (e.g., the conduit member 318) disposed above the outer surface 319 of the connector conduit 310 via friction.

[0035] During use, the barbed collar 320 facilitates the mechanical retention of a flexible conduit (e.g., gas supply line 114) positioned above the distal port 304. For example, the size of the barbed collar 320 can be determined to be larger than the proximal end of the flexible conduit of the gas supply line 114, such that when stretched on the distal port 304 and the barbed collar 320, the proximal end retracts against the barbed collar 320. The tension from the retraction of the conduit against the barbed collar 320 then applies a mechanical force to retain the proximal end of the gas supply line 114 on the distal port 304 and the connector conduit 310.

[0036] In some other embodiments, the distal portion 302 of connector 202 may not include the barbed collar 320. Alternatively, adhesives may be used to join and seal the gas supply line 114 and the distal port 304 of connector 202 together. For example, adhesive may be applied between the inner surface of the conduit for gas supply line 114 and the outer surface 317 of connector conduit 310 to join the conduit above the distal port 304.

[0037] In another embodiment, connector 202 may alternatively be inserted into distal port 304 to connect gas supply line 114 and connector 202 together. For example, distal port 304 and connector conduit 310 may be configured to have a large inner diameter such that the proximal end of the conduit for gas supply line 114 can be inserted into distal port 304 and secured along the inner surface of connector conduit 310. In this embodiment, an adhesive may be used between the outer surface of the conduit at the proximal end of gas supply line 114 and the inner surface of connector conduit 310 to seal and bond the conduit of gas supply line 114 and connector 202 together.

[0038] Go to Figure 3B and Figure 3D The proximal portion 306 includes a first locking tab 322 and a second locking tab 324 extending from the proximal side 315 of the annular flange 312. Typically, the first locking tab 322 and the second locking tab 324 enable the connector 202 and the receiver 204 to engage and lock during connection, as described in more detail below. In some embodiments, the first locking tab 322 and the second locking tab 324 are each formed as angled structures disposed on opposite sides of the connector conduit 310, such as... Figure 3DAs shown. The first locking tab 322 and the second locking tab 324 may each include a first member 340 connected to the second member 342 at a non-zero angle, forming a bend 341, wherein the first member 340 extends toward the connector conduit 310, and the second member 342 extends substantially perpendicular to the first member 340. The second member 342 has an increasing lateral thickness along its length, which begins at the bend 341 adjacent to the first member 340 and terminates at a boss 344 configured to be furthest from the first member 340. The boss 344 typically includes an overhang extending from the end of the second member 342 opposite to the bend 341 toward the outer surface 346 of the second member 342 facing away from the connector conduit 310. The second member 342 and the boss 344 are configured to flex toward the connector conduit 310 in response to a force applied to the outer surface 346 of the second member 342.

[0039] like Figure 3B As shown, the proximal portion 306 further includes a first light-blocking post 326, a second light-blocking post 328, a first aligner 330, a second aligner 332, and a removable O-ring 334 disposed along the outer surface 317 of the connector conduit 310. The first aligner 330 and the second aligner 332 extend from a ring 338 disposed adjacent to the first locking tab 322 and the second locking tab 324 and the annular flange 312. The ring 338 extends from the outer surface 317 of the connector conduit 310 and is oriented substantially parallel to the annular flange 312. The first aligner 330 and the second aligner 332 are disposed on opposite sides of the ring 338 and are each substantially perpendicular to the longitudinal flow axis of the connector conduit 310 (e.g., parallel to...). Figure 3B The ring 338 extends along the X-axis. The ring 338 is further connected to a collar 337, which is positioned proximal to the ring 338 and closer to the proximal port 308. The ring 338 is connected to the collar 337 by a plurality of support members 339 extending along the outer surface 317 of the connector conduit 310 parallel to the longitudinal flow axis of the connector conduit 310.

[0040] The first light-blocking pillar 326 and the second light-blocking pillar 328 extend from the proximal end 336 of the connector conduit 310 in an orientation substantially parallel to the longitudinal flow axis of the connector conduit 310. For example... Figure 3B and Figure 3F As shown, the first light-blocking pillar 326 and the second light-blocking pillar 328 are disposed on opposite sides of the near-side port 308, and each has an arc shape. Figure 3B and Figure 3CAs shown, the proximal portion 306 includes a channel formed between the bases of the first light-blocking post 326 and the second light-blocking post 328 near the proximal end 336 of the collar 337. An O-ring 334 is disposed in the channel, with the collar 337 on one side of the O-ring 334 and the first and second light-blocking posts 326 and 328 on the other side. As discussed in more detail below, the O-ring 334 may extend around the outer surface 317 of the connector conduit 310 and serve to form a seal in a portion of the receiver 204 when the connector 202 is inserted into the receiver 204.

[0041] Figure 3E and Figure 3F An end view of connector 202 is shown. (Turn) Figure 3E The first fin 314 and the second fin 316 are disposed on opposite sides of the distal port 304 and the connector conduit 310. For example... Figure 3B and Figure 3F As shown, the first aligner 330 and the second aligner 332 are aligned with the first locking tab 322 and the second locking tab 324 respectively disposed on the annular flange 312 on opposite sides of the connector conduit 310. Therefore, the first aligner 330 and the second aligner 332 are each disposed across the first locking tab 322 and the second locking tab 324, such that the first aligner 330 and the second aligner 332 are similarly disposed on opposite sides of the connector conduit 310.

[0042] As described in more detail below, the first aligner 330 and the second aligner 332 ensure that the connector 202 is correctly oriented when the user connects the connector 202 to the receiver 204. Although the first aligner 330 and the second aligner 332 are shown positioned on opposite sides of the connector conduit 310 (e.g., 180 degrees opposite each other), the first aligner 330 and the second aligner 332 may also be positioned opposite each other in an alternative arrangement. For example, in some other embodiments, the first aligner 330 and the second aligner 332 may extend perpendicularly to each other, with the first locking tab 322 and the second locking tab 324 correspondingly aligned. In another embodiment, the connector 202 may include only one aligner or more than two aligners, with the receiver 204 similarly configured to receive its corresponding connector 202. In another embodiment, the connector 202 may also include only one locking tab or more than two locking tabs, with the receiver 204 similarly configured to lock the connector 202 and the corresponding receiver 204 together.

[0043] Figures 4A to 4CPerspective and cross-sectional views of an exemplary receiver 204 according to certain embodiments are shown. The receiver 204 generally includes a housing 400 having a receiver port 404 located at a distal end 402 and a base 408 disposed at a proximal end 403. The receiver port 404 is configured to receive a proximal portion 306 of a connector 202 when the connector 202 is coupled to the receiver 204. The base 408 includes a pair of holes 410 to facilitate attachment and / or integration of the receiver 204 with a surgical console 100 at the port 106. The proximal end 403 of the receiver 204 also includes a supply port 412 extending through the base 408. The receiver 204 can be made of any material commonly used for such receivers and suitable for use with an ophthalmic surgical console. For example, the receiver 204 can be formed from thermoplastic polymers and other polymeric materials, lightweight aluminum, anodized aluminum, stainless steel and other metal alloys, or other suitable materials. When receiver 204 is integrated with a surgical console (such as surgical console 100), supply port 412 can be in fluid communication with infusion gas source 430, which is integrated with or connected to the console.

[0044] like Figure 4C As shown, receiver port 404 is also in fluid communication with supply port 412 via chamber 414 and receiver conduit 416 extending through receiver 204. When connector 202 is connected to receiver 204, connector conduit 310 of connector 202 is in fluid communication with receiver conduit 416 of receiver 204, thereby allowing gas (e.g., low-pressure air) to flow bidirectionally between gas supply line 114 and infusion gas source 430 through connector 202 and receiver 204. In some other embodiments, supply port 412 integrated with surgical console 100 may alternatively or additionally be in fluid communication with a vacuum source.

[0045] The receiver port 404 of receiver 204 can be sized and shaped to receive the proximal portion 306 of connector 202, including a first aligner 330 and a second aligner 332. In other words, receiver port 404 can have a morphology substantially corresponding to the morphology of the proximal portion 306, such that the proximal portion 306 fits within receiver port 404 of receiver 204 with desired tolerances. In some examples, coupling connector 202 to receiver 204 also includes aligning one or more mating / engaging features between them. In some embodiments, receiver port 404 may include a first aligner notch 418 opposite to the second aligner notch 420, each sized and shaped to receive a corresponding first aligner 330 and second aligner 332 of connector 202. Therefore, the size of the receiver port 404 can be determined such that the proximal portion 306 of the connector 202 can be assembled through the receiver port 404 when the first aligner 330 and the second aligner 332 of the connector 202 are aligned with the first aligner recess 418 and the second aligner recess 420. When the connector 202 and receiver 204 are in use, the alignment of the first aligner 330 and the second aligner 332 with the first aligner recess 418 and the second aligner recess 420 also facilitates the correct orientation of the connector 202 when it is inserted into the receiver 204.

[0046] The inner surface of the receiver port 404 may further include a first locking protrusion 422, a second locking protrusion 424, a first locking recess 423, and a second locking recess 425. The first locking protrusion 422 is adjacent to the first locking recess 423 and is disposed opposite to the second locking protrusion 424. The second locking recess 425 is adjacent to the second locking protrusion 424 and is disposed opposite to the first locking recess 423. As described in more detail below, the first locking protrusion 422 and the second locking protrusion 424, as well as the adjacent first locking recess 423 and the second locking recess 425, are respectively configured to engage with the first locking tab 322 and the second locking tab 324 of the connector 202 to temporarily lock the connector 202 and the receiver 204 together during connection.

[0047] The housing 400 also includes opposing first and second light-transmitting apertures 426 and 428. The first and second light-transmitting apertures 426 and 428 are configured to receive light propagating through the light tube from an external environment (such as the surgical console 100) when the receiver 204 is integrated into the surgical console for use with port 106. As described in the following additional details, the first and second light-transmitting apertures 426 and 428 enable the surgical console 100 to allow light to propagate through the chamber 414 of the receiver 204 for use in detecting proper connection between the connector 202 and the receiver 204. The first and second light-transmitting apertures 426 and 428 are positioned towards the proximal end of the chamber 414 so that light propagating through it can be used to detect when the connector 202 is securely and fully inserted into the receiver 204.

[0048] Figures 5A to 5C Demonstrates use according to certain embodiments Figure 2A and Figure 2B A perspective view of the connector assembly 200 depicted in the figure. Figure 6A and Figure 6B Showing respectively from Figure 5B Section lines 6A-6A and Figure 5C The section view of connector assembly 200 seen through section lines 6B-6B is shown in the figure. Therefore, for clarity, this document will... Figures 5A to 5C as well as Figure 6A and Figure 6B Describe them together.

[0049] In operation, connector 202 is connected to receiver 204 by inserting the proximal portion 306 of connector 202 into receiver port 404. For example... Figure 5A As shown, to aid in proper alignment of the connector during initial insertion of the proximal portion 306 of the connector 202, the first aligner 330 and the second aligner 332 of the connector 202 are aligned with the first aligner recess 418 and the second aligner recess 420 of the receiver port 404, allowing the proximal portion 306 of the connector 202 to assemble and insert through the receiver port 404. When the proximal portion 306 of the connector 202 is positioned within the receiver port 404, the annular flange 312 of the connector 202 is adjacent to the distal end 402 of the receiver 204, as... Figure 5B As shown. When connector 202 is inserted into receiver 204, proximal portion 306 (including proximal port 308 and first light-blocking post 326 and second light-blocking post 328) extends into chamber 414. The proximal ends of the first light-blocking post 326 and second light-blocking post 328 are disposed adjacent to the distal end of receiver conduit 416.

[0050] When connector 202 is inserted into receiver 204, O-rings 334 adjacent to the first and second light-blocking posts 326 and 328 are also disposed within chamber 414. In some embodiments, O-rings 334 include gaskets configured to form a seal in chamber 414 in the space between the proximal port 308 and the distal end of receiver conduit 416 when connector conduit 310 is disposed in chamber 414. The first and second light-blocking ports 426 and 428 may also each be disposed with O-rings or other seals for further sealing chamber 414 of receiver 204. The seal formed by O-rings 334 and any other O-rings in chamber 414 helps prevent gas flowing between connector conduit 310 and receiver conduit 416 from leaking out of chamber 414. O-rings 334 may be made of any material typically used for such gaskets to form a seal between connecting components. For example, the O-ring 334 can be formed of rubber (such as natural rubber, neoprene rubber, nitrile rubber, etc.). Lubricant can also be applied together with the O-ring 334 to help form a seal and to insert and withdraw the connector 202 into the receiver 204.

[0051] In some embodiments, such as Figure 5B and Figure 5C As shown, connector assembly 200 includes a locking mechanism in which connector 202 rotates when proximal portion 306 is inserted into receiver 204 to temporarily lock connector 202 and receiver 204 together. When connector assembly 200 is in this locked state, the user then needs to intentionally rotate connector 202 in the opposite direction to unlock and disconnect connector 202 from receiver 204. Therefore, the locking mechanism helps maintain the connection between connector 202 and receiver 204 during surgical procedures by preventing accidental disconnection of connector 202 and the gas supply line 114 connected to the connector during the procedure.

[0052] For example, such as Figure 6A As shown, when connector 202 is as Figure 5B When inserted into receiver 204, connector assembly 200 is initially in an unlocked state, where connector 202 can freely translate through receiver port 404. In this unlocked state, since inserting connector 202 through receiver port 404 requires initial alignment of first aligner 330 and second aligner 332, the first locking tab 322 and second locking tab 324 of connector 202 remain aligned within the first aligner notch 418 and second aligner 420. When the proximal portion 306 of connector 202 is inserted into receiver port 404, connector 202 can rotate, as shown... Figure 5CAs shown (e.g., using a first fin 314 and a second fin 316 extending from the distal portion 302), the connector assembly 200 is transitioned from an unlocked state to a locked state to temporarily lock the connector 202 and the receiver 204 together.

[0053] Go to Figure 6B When connector 202 rotates, the rotation of connector 202 also causes the first locking tab 322 and the second locking tab 324 of connector 202 to rotate and move along the inner surface of receiver port 404. Figure 6A In the example shown, due to the shape of the receiver port 404, the connector 202 is restricted to rotating clockwise so that the first locking tab 322 and the second locking tab 324 move toward the first locking recess 423 and the second locking recess 425, respectively.

[0054] As the first locking tab 322 and the second locking tab 324 move along the inner surface of the receiver port 404 during insertion, the connector 202 can rotate until each of the second members 342 of the first locking tab 322 and the second locking tab 324 contacts the first locking protrusion 422 and the second locking protrusion 424 respectively and engages with the first locking recess 423 and the second locking recess 425. The shape and size of the first locking protrusion 422 and the second locking protrusion 424 can be determined such that the protrusions 344 of the first locking tab 322 and the second locking tab 324 initially impede further movement of the first locking tab 322 and the second locking tab 324 when they initially contact each other during rotation. However, if the user applies a sufficiently large rotational force, the second members 342 of the first locking tab 322 and the second locking tab 324 can each flex when the user pushes the protrusions 344 of the first locking tab 322 and the second locking tab 324 against the first locking protrusions 422 and the second locking protrusion 424. The combination of the rotational force provided by the user and the flexure of the second component 342 enables the user to move the boss 344 past the first locking protrusion 422 and the second locking protrusion 424 and into the first locking recess 423 and the second locking recess 425 respectively, so as to lock the connector 202 and the receiver 204 together.

[0055] When the connector assembly 200 is in the locked state, the bosses 344 of the first locking tab 322 and the second locking tab 324 interlock with each other within the first locking recess 423 and the second locking recess 425, respectively. Therefore, once the bosses 344 of the first locking tab 322 and the second locking tab 324 engage with the first locking recess 423 and the second locking recess 425, the first locking recess 423 and the second locking recess 425 also prevent the first locking tab 322 and the second locking tab 324, and thus prevent the connector 202 from rotating further, as... Figure 6BAs shown. During operation, the locking mechanism enables the connector assembly 200 to provide tactile feedback to the user when the connector 202 is rotated into the locked state. Specifically, when the boss 344 contacts and engages with the first locking recess 423 and the second locking recess 425, the deflection of the first locking tab 322 and the second locking tab 324, as well as the pushing of the boss 344 through the first locking protrusion 422 and the second locking protrusion 424, causes the connector 202 to "lock". Therefore, the tactile feedback serves as an indication to the user that the connector 202 has been successfully locked when the connector 202 and the receiver 204 are connected.

[0056] When the protrusions 344 of the first locking tab 322 and the second locking tab 324 engage with the first locking recess 423 and the second locking recess 425, respectively, the first locking tab 322 and the second locking tab 324 can correspondingly flex and apply a biasing force to the outer surface 346 of the second member 342 of the first locking protrusion 422 and the second locking protrusion 424 and the second locking tab 322 and the second locking tab 324. This biasing force helps to maintain the engagement between the first locking tab 322 and the second locking tab 324 and the first locking recess 423 and the second locking recess 425, respectively, to keep the connector assembly 200 in a locked state. When in the locked state, rotation of the connector 202 (e.g., displacement of the first aligner 330 and the second aligner 332 away from the first aligner recess 418 and the second aligner recess 420) also causes the first aligner 330 and the second aligner 332 to be axially aligned with and / or in contact with the inner surface of the receiver 204 at the distal end 402. Therefore, the misalignment between the first aligner 330 and the second aligner 332 and the first aligner recess 418 and the second aligner recess 420 caused by the rotation of the connector 202 (to lock the connector 202) further helps to prevent the connector 202 from accidentally disconnecting from the receiver 204 when locked.

[0057] Connector 202 can be correspondingly unlocked from receiver 204 by rotating it in opposite directions (e.g., counterclockwise) with a force sufficient to push the protrusions 344 of the first locking tab 322 and the second locking tab 324 past the first locking protrusion 422 and the second locking protrusion 424. Sufficient force is required to overcome the biasing force between the first locking protrusion 422 and the second locking protrusion 424 and the second member 342, which correspondingly reduces the likelihood of accidentally disconnecting connector 202, as this force typically requires intentional application by the user. To return connector assembly 200 to its unlocked state and retract connector 202 from receiver port 404, connector 202 can be rotated to realign the first aligner 330 and the second aligner 332 with the first aligner recess 418 and the second aligner recess 420, so that the proximal portion 306 can then be retracted from receiver port 404, thereby disconnecting connector 202 from receiver 204.

[0058] Figure 7A and Figure 7B Demonstrates, according to certain embodiments, such as Figure 5B and Figure 5C The corresponding three-dimensional cross-sectional view of the connector assembly 200 depicted in the image. Meanwhile, Figure 7C Demonstrates certain embodiments Figure 5C and Figure 7B The corresponding cross-sectional side view of the connector assembly 200 depicted in the image. Therefore, for clarity, this document will... Figures 7A to 7C Describe them together.

[0059] In some embodiments, rotation of connector 202 relative to receiver 204 enables detection of when connector assembly 200 is in a locked state. As discussed above, in some embodiments, receiver 204 may be integrated with surgical console 100. In this example, a first light tube aperture 426 and a second light tube aperture 428 disposed on opposite sides of housing 400 may be connected to light tube 700 and sensor 702, respectively, for light to propagate between the first light tube aperture 426 and the second light tube aperture 428 and through chamber 414. In some embodiments, light tube 700 includes a light-emitting diode (LED), an LED light tube, a laser emitting source, or other light source, and sensor 702 includes its corresponding sensor or detector. In use, light from light tube 700 can propagate from the first light tube aperture 426 toward the second light tube aperture 428 and the sensor 702 connected to the second light tube aperture.

[0060] When the connector assembly 200 is not locked, the space between the first light tube aperture 426 and the second light tube aperture 428 in the chamber 414 is unobstructed, thereby allowing light from the light tube 700 to propagate through the chamber 414 and be received and / or detected by the sensor 702. When the connector assembly 200 is locked and the first light-blocking post 326 and the second light-blocking post 328 are disposed within the chamber 414, the sizes of the first light-blocking post 326 and the second light-blocking post 328 are determined to be sufficient to block the first light tube aperture 426 and the second light tube aperture 428 when the connector 202 is inserted and rotated (e.g., to lock the connector 202). Blocking the first light tube aperture 426 and the second light tube aperture 428, and consequently blocking the propagation of light from the light tube 700, can be detected by the surgical console 100 via the sensor 702. The surgical console 100 can therefore use the detection of light from the extension of the light tube 700 passing through the chamber 414 (and the corresponding inability to detect light when the light tube openings 426, 428 are blocked) as a mechanism for detecting when the connector 202 is fully inserted into the receiver 204 and rotated sufficiently to turn the connector assembly 200 into a locked state.

[0061] For example, when connector 202 is first inserted into receiver 204 and before connector 202 rotates, as Figure 5B and Figure 6A As shown, the first light tube aperture 426 and the second light tube aperture 428 remain unobstructed in the insertion chamber 414 of the connector 202. With the first light tube aperture 426 and the second light tube aperture 428 unobstructed, light from the light tube 700 continues to propagate through the chamber 414, while the surgical console 100 detects the light accordingly (e.g., sensor 702 continues to receive the light). The surgical console 100 can then use the continuous detection of light from the light tube 700 as an indication to determine that the connector 202 has not been fully inserted and / or rotated to lock with the receiver 204. This determination by the surgical console 100 that the connector 202 and the gas supply line 114 coupled to the connector may not be properly connected can prevent the surgical console 100 from initiating a gas flow from the infusion gas source 430. In some embodiments, as long as the surgical console 100 is turned on, the light tube 700 and the sensor 702 can continue to operate, so that the light from the light tube 700 continues to propagate between the first light tube aperture 426 and the second light tube aperture 428 until the apertures 426 and 428 are blocked accordingly by the insertion and rotation of the connector 202.

[0062] After connector 202 is inserted into receiver port 404, as follows Figure 5C and Figure 6BAs shown, during rotation, the rotation of connector 202 causes the first light-blocking post 326 and the second light-blocking post 328 extending from the proximal end 336 of connector conduit 310 to translate within chamber 414. Figure 7B and Figure 7C As shown, when connector 202 is fully rotated so that connector assembly 200 is in the position shown... Figure 5C In the locked state shown, the rotation of connector 202 causes the first light-blocking post 326 and the second light-blocking post 328 to translate to positions that block and impede the propagation of light from the light tube 700 between the first light tube aperture 426 and the second light tube aperture 428, as well as the corresponding position for the sensor 702 to receive the light.

[0063] When the sensor 702 of the surgical console 100 fails to detect the propagation of light from the light tube 700, the surgical console 100 can use the failure of the sensor 702 to detect light as an indication that the connector 202 has been inserted and fully rotated to transition the connector assembly 200 to a locked state. Using the light from the light tube 700 and the corresponding detection of the light by the surgical console 100 to indicate when the connector 202 is inserted and locked allows the surgical console 100 to also provide corresponding notification to the user. In some embodiments, the surgical console 100 may provide visual notification of the locking status of the connector 122 on the display 120 to help surgeons and / or surgical staff confirm that all necessary connectors of the surgical console 100 are correctly connected and locked before the start of the procedure.

[0064] In some embodiments, the first light-blocking aperture 426 and the second light-blocking aperture 428 may also each be configured with an O-ring 704 to help form a seal in the chamber 414. As discussed above, an O-ring 334 on the connector conduit 310 may also be disposed in the chamber 414 when the connector 202 is inserted into the receiver 204. When the connector 202 rotates and locks to provide indication to the surgical console 100 via blocking the first light-blocking aperture 426 and the second light-blocking aperture 428, the surgical console 100 can, as discussed above, notify the user that the connector 202 is correctly connected and ready to initiate a gas flow from the infusion gas source 430. Because the first light-blocking post 326 and the second light-blocking post 328 extend within the chamber 414, the connector conduit 310 does not directly contact the receiver conduit 416. Therefore, when gas is delivered from the infusion gas source 430, the gas flows from the supply port 412 through the receiver conduit 416 and the chamber 414 to the connector conduit 310 and the gas supply line 114 connected to the distal port 304. The combination of the O-ring 334 on the connector conduit 310 and the O-ring 704 adjacent to the first aperture 426 and the second aperture 428 can thus help maintain a seal in the chamber 414 as the gas flows between the connector conduit 310 and the receiver conduit 416, thereby maintaining the pressure of the gas supplied to the gas supply line 114 during the surgical procedure.

[0065] In summary, embodiments of this disclosure include structures and mechanisms for facilitating and improving the setup of surgical consoles during ophthalmic procedures, and particularly for improved port connector assemblies for intraocular fluid infusion. The aforementioned connector assemblies include embodiments capable of temporarily locking the connector and the corresponding receiver / port of the surgical console together by rotating the connector after insertion. When integrated with a surgical console, the receiver can also be configured to utilize the rotation of the connector while locking it, further providing the surgical console with a mechanism to detect / determine when the connector is inserted and rotated sufficiently to ensure proper connection and locking of the connector and receiver. Therefore, the aforementioned connector assemblies are particularly beneficial in helping users (such as surgeons and surgical assistants) ensure proper connection of supply lines used to deliver infusion gases prior to the surgical procedure and to maintain this connection throughout such procedures.
