DETAILED DESCRIPTION

[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted. In addition, the drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0042] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0043] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0044] In the present disclosure, the words "perpendicular" and "equal" refer to perpendicularity and equality within the process error range, not perpendicularity and equality in an absolute sense. The process error may be within ±10% or ±5%. For example, if the first direction is perpendicular to the second direction, it can be understood that the angle between the first direction and the second direction may be 90°±5°.

[0045] In the related art, the Y-valve assembly generally includes a Y-valve and a sealing rotating head connected to a port at one end of the Y-valve. The Y-valve includes a Y-valve main pipe and a Y-valve branch pipe. The port of the Y-valve branch pipe can be connected to a high-pressure connector for connecting external equipment to inject contrast agents or other liquids such as saline or heparin. One end of the Y-valve main pipe is connected to the high-pressure connector, and the other end is connected to the sealing plug rotating head. By the doctor manually rotating the sealing plug rotating head clockwise or counterclockwise to the appropriate position, it can allow the interventional consumables to smoothly enter the Y-valve while preventing the backflow of human blood. In the related art, the operation of manually rotating the sealing rotating head is relatively cumbersome and prone to errors, which brings great safety hazards to medical work.

[0046] Based on this, Figure 1 and Figure 2 As shown, an embodiment of the present disclosure provides a Y-valve assembly, including a Y-valve 100 and an exhaust device 200. The Y-valve 100 can be passed through by an interventional consumable. The exhaust device 200 is connected to the insertion end of the Y-valve 100, that is, the insertion end of the Y-valve main pipe 110. The exhaust device 200 includes a shell 210 and an exhaust adjustment component 220 disposed in the shell 210. The shell 210 is provided with an exhaust hole 211 connected to the inner cavity of the Y-valve 100. The exhaust adjustment component 220 is used to open or close the exhaust hole 211 following the change in the amount of liquid in the Y-valve 100.

[0047] The Y-valve assembly provided by the present disclosure includes a Y-valve 100 and an exhaust device 200, and the exhaust device 200 includes a housing 210 and an exhaust adjustment component 220 disposed in the housing 210. The exhaust adjustment component 220 can open or close the exhaust hole 211 on the housing 210 under the buoyancy of the liquid in the Y-valve 100 to achieve the purpose of automatic exhaust. The exhaust device 200 of the present disclosure uses the change of the liquid content in the Y-valve 100 as a driving source to achieve automatic exhaust of the Y-valve 100. Compared with the manual exhaust operation in the prior art, the present disclosure simplifies the links in the doctor's surgical process, reduces the workload, is simple and time-saving, and is convenient to operate, reduces the risk of surgery, and improves the efficiency of surgery.

[0048] The following will describe in detail the various parts of the Y-valve assembly provided in the embodiment of the present disclosure in conjunction with the accompanying drawings:

[0049] like Figures 1 to 3 , Figures 5 to 8 As shown, the Y-valve assembly provided by the present disclosure can be used for interventional surgery, especially vascular interventional surgery. The Y-valve assembly can be installed on a vascular interventional surgery robot to perform vascular interventional surgery. The slave end of the vascular interventional surgery robot includes a robot body and a slave end actuator. The robot body includes a driving device, which is used to drive the slave end actuator to move. Specifically, a sliding groove is provided on the shell of the robot body, and the driving device is arranged in the shell, and the driving device can drive the slave end actuator to slide along the sliding groove. The vascular interventional surgery robot also includes a mechanical arm, which can simulate the freedom and flexibility of a human arm and drive the robot body to achieve multi-axis displacement and rotation within a certain range. The slave end actuator may include a sterile consumable box, and the Y-valve assembly may be arranged in the sterile consumable box. The sterile consumable box may include an interventional consumable delivery mechanism for realizing the movement of the interventional consumable in the blood vessel, such as rotation, forward or backward. The Y-valve assembly can cooperate with the interventional consumable delivery mechanism to complete operations such as delivery of interventional consumables.

[0050] The vascular interventional surgical robot also includes a master control device, which may include structures such as a control element and a display screen, and is connected to the slave end for communication. The doctor can control the movement of the slave end through the control element, thereby controlling the movement of the interventional consumables. The display screen can be used to display images of the interventional consumables in human blood vessels and some operation information. The doctor can adjust the hand movements according to the images and other information displayed on the display screen to change the movement of the interventional consumables in the blood vessels.

[0051] The Y valve assembly includes a Y valve 100 and an exhaust device 200. The exhaust device 200 includes a housing 210 and an exhaust adjustment component 220 disposed in the housing 210. The exhaust adjustment component 220 can adjust the Y valve 100 to exhaust air under the buoyancy of the liquid in the Y valve 100.

[0052] The Y-valve 100 is used to connect the guide wire, the catheter and the liquid inlet device. The Y-valve 100 includes a Y-valve main pipe 110 and a Y-valve branch pipe 120 connected to one side of the Y-valve main pipe 110. The Y-valve branch pipe 120 is connected to the Y-valve main pipe 110. The Y-valve branch pipe 120 is used to provide a liquid injection channel. One end of the Y-valve main pipe 110 is an outlet end for connecting the catheter, and the other end is an insertion end for inserting the guide wire. After the guide wire is inserted, it passes through the outlet end of the Y-valve main pipe and enters the catheter. The head end of the guide wire passes through the outside of the catheter and plays a role in guiding the catheter to intervene in the blood vessel.

[0053] The exhaust device 200 is connected to the insertion end of the Y valve 100. The exhaust device 200 includes a housing 210 and an exhaust adjustment component 220 disposed in the housing 210.

[0054] The shell 210 is a hollow structure, and its inner cavity is connected to the inner cavity of the Y valve 100, specifically, it can be connected to the inner cavity of the Y valve main pipe 110. The shell 210 is provided with an exhaust hole 211, and the exhaust hole 211 penetrates the shell wall of the shell 210 to connect the outside with the inner cavity of the Y valve 100. Optionally, the exhaust direction of the exhaust hole 211 is roughly parallel to the penetration direction of the interventional consumables.

[0055] In some embodiments of the present disclosure, the housing 210 may include a bottom shell 212 and a top cap 213. The bottom shell 212 is connected to the Y-valve main pipe 110. The bottom shell 212 may be a hollow structure with an open top, and the top cap 213 is connected to the open end of the bottom shell 212. The connection between the top cap 213 and the bottom shell 212 may be a detachable connection, and the two may be connected by means of threads, buckles, etc. Figure 5 and Figure 6 As shown, the bottom wall of the bottom shell 212 may be provided with a first insertion portion 214, which protrudes from the bottom wall of the bottom shell 212 and is used to connect with the Y-valve main pipe 110. A gas channel 14a is provided through the first insertion portion 214 to connect the inner cavity of the shell 210 and the inner cavity of the Y-valve main pipe 110. The extension direction of the gas channel 14a is substantially perpendicular to the insertion direction of the interventional consumable, that is, substantially perpendicular to the extension direction of the Y-valve main pipe 110.

[0056] The exhaust adjustment component 220 is located in the housing 210. The exhaust adjustment component 220 is used to open or close the exhaust hole 211 following the change in the amount of liquid in the Y valve 100. In some embodiments of the present disclosure, the exhaust adjustment component 220 includes a float 221 and a switch component 222.

[0057] like Figures 2 to 4As shown, the float 221 is movably arranged in the housing 210, and is used to float or descend with the liquid in the Y-valve 100, and the floating direction of the float 221 is substantially perpendicular to the insertion direction of the interventional consumables. When there is no liquid or the liquid content is insufficient in the Y-valve 100, the float 221 is in a sinking state. When the liquid content in the Y-valve 100 is sufficient and the liquid surface can contact the bottom of the float 221, the float 221 can start to float up. Optionally, as Figure 4 , Figure 8 As shown, a second inserting portion 2211 is provided at the bottom end of the float 221. The second inserting portion 2211 can pass through the gas channel 14a of the first inserting portion 214 and protrude from the bottom end of the first inserting portion 214 in a sunken state.

[0058] Optionally, a second exhaust channel 21a is provided in the float 221, and the second exhaust channel 21a connects the inner cavity of the Y valve 100 and the inner cavity of the shell 210, and the extension direction of the second exhaust channel 21a is perpendicular to the insertion direction of the interventional consumables.

[0059] like Figure 2 , Figures 5 to 8 As shown, the switch assembly 222 is connected to the float 221, and the switch assembly 222 includes a movably connected control unit and an exhaust unit 2223. The exhaust unit 2223 is provided with a first exhaust channel 23a, and the first exhaust channel 23a connects the inner cavity of the shell 210 and the outside. The exhaust unit 2223 is arranged at the exhaust hole 211, and the control unit is connected to the float 221, and is used for opening or closing the first exhaust channel 23a when the float 221 floats.

[0060] Alternatively, if Figure 4 As shown, the top of the float 221, that is, the end away from the Y-valve main pipe 110, is provided with a first groove 21b, and the control unit can be connected to the first groove 21b. Figure 6 , Figure 8 As shown, the second exhaust channel 21a can be arranged in the second inserting portion 2211 and extend to the first groove 21b and communicate with the first groove 21b. When the control unit opens the first exhaust channel 23a under the action of the float 221, the gas in the Y valve 100 can pass through the second exhaust channel 21a, the inner cavity of the housing 210, and finally be discharged from the first exhaust channel 23a.

[0061] like Figure 2 , Figure 6 and Figure 8 As shown, in some embodiments of the present disclosure, the control unit includes a control rod 2221 and an elastic member 2222. One end of the control rod 2221 is connected to the float 221, and the other end is connected to the exhaust unit 2223 through the elastic member 2222. The elastic member 2222 is a hollow structure. The control rod 2221 drives the elastic member 2222 to switch between a straight state and a curved state under the drive of the float 221. Figure 5 and Figure 6 As shown, in the straight state, one end of the control rod 2221 abuts against the first exhaust channel 23a of the exhaust portion 2223, so that the first exhaust channel 23a is in a closed state; Figure 7 and Figure 8 As shown, in the bent state, one end of the control rod 2221 is separated from the first exhaust channel 23a of the exhaust portion 2223, so that the first exhaust channel 23a is in an open state. At this time, the gas in the Y valve 100 can pass through the second exhaust channel 21a, the inner cavity of the housing 210, and finally be discharged from the first exhaust channel 23a.

[0062] Optionally, the elastic member 2222 may be a spring. One end of the spring is sleeved on the control rod 2221, and the other end is sleeved on the exhaust portion 2223. The control rod 2221 may be a solid rod, and the exhaust portion 2223 may be a hollow rod, with the first exhaust passage 23a formed by the hollow interior. One end of the control rod 2221 is connected to the groove of the float 221, and the specific connection method thereof may not be limited. For example, one end of the control rod 2221 may be connected to the groove wall of the groove by a hook, an adhesive layer, etc., or may be limited to the groove by a railing across the groove. The exhaust portion 2223 is provided at the exhaust hole 211, and may be partially or completely located in the housing 210. For example, the exhaust portion 2223 may be inserted into the exhaust hole 211, or connected between the control rod 2221 and the shell wall of the housing 210, and the first exhaust passage 23a is communicated with the exhaust hole 211.

[0063] When the float 221 floats up or sinks, one end of the control unit connected to the float 221 will move upward or downward driven by the float 221, and pull the other end of the control rod 2221 to drive the spring to move, so that the spring switches between a straight state and a bent state.

[0064] like Figure 2 , Figure 5 and Figure 7 As shown, in some embodiments of the present disclosure, the Y-valve assembly further includes a sealing assembly 300, which is sealed and connected to the insertion end of the Y-valve 100. The sealing assembly 300 includes a sealing pad 310 and a sealing valve cap 320. The sealing valve cap 320 is detachably connected to the insertion end of the Y-valve 100, and the sealing pad 310 is connected between the insertion end of the Y-valve 100 and the sealing valve cap 320. The sealing pad 310 can be made of an elastic material and has a certain elastic deformation ability. Specifically, the sealing pad 310 can be a rubber pad. The guide wire can pass through the sealing pad 310 to enter the Y-valve 100. Among them, the guide wire can enter the Y-valve 100 with the help of an introduction member. The introduction member has an inner cavity for the guide wire to pass through. The structural strength of the introduction member can be greater than the guide wire so as to penetrate the sealing pad 310.

[0065] Alternatively, if Figure 2 and Fig. 9 As shown, the sealing gasket 310 includes an insertion area 311, and the thickness of the sealing gasket 310 in the insertion area 311 is less than the thickness of other areas. It is understandable that since the thickness of the insertion area 311 is relatively thin, it can be understood as a weak area with low structural strength, which is convenient for the insertion of the introduction member and the guide wire. The insertion area 311 can be formed by thinning the surface of one side of the sealing gasket 310 close to the sealing valve cap 320. The shape of the thinned area can be set according to the actual shape. For example, the thinned area can be a cross shape, a cross shape, etc. Preferably, the thinned area is a cross shape. That is, a cross-shaped groove is provided on the surface of one side of the sealing gasket 310 close to the sealing valve cap 320, and the cross-shaped groove forms the insertion area 311.

[0066] Under normal circumstances, the insertion area 311 is not penetrated and is in a tightly closed state. When it is necessary to insert the guide wire into the Y valve 100, the sealing valve cap 320 can be detached, and the introduction component can be inserted into the insertion area 311 of the sealing gasket 310. At this time, the sealing gasket 310 is deformed by the external thrust, and the insertion area 311 expands until it opens. The introduction component enters the insertion area 311 and can move forward, retreat, and other operations therein. In this process, the rubber pad fits tightly with the introduction component. When the thrust disappears, the insertion area 311 is close to closed, and the insertion end is in a sealed state. At this time, blood can be prevented from seeping out, and the liquid in the Y valve 100 can also be prevented from leaking out from here.

[0067] The exhaust process of the Y-valve assembly will be described in detail below in combination with specific practical application scenarios.

[0068] In practical applications, such as Figure 7 and Figure 8 As shown, when the Y-valve 100 is not in use, there is no liquid in the Y-valve 100, the float 221 is in a sinking state, and the end of the control rod 2221 connected to the float 221 moves downward under the action of the float 221, and pulls the other end of the control rod 2221 to move, so that the elastic member 2222 is deformed and in a bent state. The control rod 2221 is separated from the exhaust portion 2223, and the first exhaust channel 23a is in an open state.

[0069] When the Y-valve 100 is used, the outlet end of the Y-valve 100 can be connected to a catheter; the insertion end of the Y-valve 100 is in a sealed state; the required liquid can be injected from the end of the Y-valve branch pipe 120. Since the insertion end of the Y-valve 100 is in a sealed state, and the outlet end of the Y-valve 100 is connected to the human body, when liquid is injected, the air in the Y-valve 100 will float above the liquid, and the air will be gradually squeezed into the exhaust device 200 as the liquid is injected, and discharged through the first exhaust channel 23a until the liquid fills the entire Y-valve 100, and the gas in the Y-valve 100 is completely discharged, thereby preventing air from entering the human body and causing gas embolism.

[0070] When the gas is exhausted, Figure 5 and Figure 6 As shown, the float 221 floats up under the buoyancy of the liquid, and the end of the control rod 2221 connected to the float 221 moves upward under the drive of the float 221, and pulls the other end of the control rod 2221 to drive the elastic member 2222 to move, so that the elastic member 2222 is converted from a bent state to a straight state. At this time, the control rod 2221 abuts against the first exhaust channel 23a of the exhaust part 2223, so that the first exhaust channel 23a is in a closed state. At this point, the entire Y valve 100 is exhausted, and the cavity of the Y valve 100 is filled with liquid.

[0071] Alternatively, if Figure 2 and Figure 3 As shown, a first connection hole 1131 is provided on the side of the insertion end of the Y-valve 100. Specifically, the Y-valve main pipe 110 includes a head 111, a main body 112 and a tail 113 connected in sequence. Among them, the tail 113 can be the insertion end of the Y-valve 100. The tail 113 of the Y-valve 100 is provided with a first connection hole 1131. The exhaust device 200 is connected to the first connection hole 1131, and the distance between the center of the first connection hole 1131 and the end face of the insertion end accounts for 1 / 20-1 / 8 of the length of the Y-valve 100, which can be specifically 1 / 20, 1 / 19, 1 / 18, 1 / 17, 1 / 16, 1 / 15, 1 / 14, 1 / 13, 1 / 12, 1 / 11, 1 / 10, 1 / 9 or 1 / 8, etc., but is not limited thereto. Within this range, the distance between the installation position of the exhaust device 200 on the Y valve 100 and the end face of the insertion end is relatively appropriate. Within this distance range, on the one hand, it can prevent the liquid in the Y valve 100 from generating a large impact force near the insertion end and forming bubbles due to the distance between the two being too close; on the other hand, it can also prevent the liquid entering from the Y valve branch pipe 120 from being unable to flow to the space near the insertion end in time due to the distance between the two being too far, resulting in difficulty in exhausting the air near the insertion end of the Y valve 100, resulting in poor exhaust effect. Preferably, the distance between the center of the first connecting hole 1131 and the end face of the insertion end accounts for 1 / 15-1 / 8 of the inner cavity length of the Y valve 100.

[0072] like Figure 2 , Figure 5 and Figure 7 As shown, in some embodiments of the present disclosure, the Y-valve assembly further includes a rotating assembly 400 connected to the outlet end of the Y-valve 100, and the rotating assembly 400 includes a rotating base 410 rotatably connected to the port of the outlet end, and the rotating base 410 is penetrated by a through hole 411 connected to the inner cavity of the Y-valve 100, and the through hole 411 is used for the interventional consumables to pass through, and specifically, a guide wire can be passed through. The rotating base 410 is used to drive the catheter inside it to rotate under the drive of the outside.

[0073] Furthermore, the rotating assembly 400 further includes a sealing ring 420, which is disposed at the connection between the rotating base 410 and the port at the outlet end, so as to prevent the outside air from entering the Y valve 100 when the rotating base 410 rotates. The sealing ring 420 can be made of an elastic material, such as a rubber ring. Specifically, the sealing ring 420 can be located between the contact surface between the port at the outlet end of the Y valve 100 and the rotating base 410.

[0074] The rotating assembly 400 may also include a sealing gland 430, which is sleeved in the area of ​​the port of the Y valve 100 near the outlet. Specifically, the sealing gland 430 can be sleeved on the head 111 of the Y valve main pipe 110. A groove is provided on the side surface of the sealing gland 430 near the outlet port, and part of the structure of the rotating base 410 can be abutted against the end face of the outlet, part of the structure can be sleeved on the periphery of the head 111 of the Y valve main pipe 110, and part of the structure can be inserted in the groove of the sealing gland 430. The combination of the sealing ring 420 and the sealing gland 430 helps to improve the sealing effect, wherein the main function of the sealing ring 420 is to fill and seal the gap, ensure that the outside air does not enter the Y valve 100, and the liquid in the Y valve 100 does not leak. The sealing gland 430 presses the sealing ring 420 tightly on the sealing surface (the contact surface between the rotating base 410 and the outlet port) by applying pressure, thereby increasing the reliability of the seal. The double seal design can improve the sealing effect and reduce the probability of leakage.
