Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a valve and a vascular interventional surgery component. Background Art

[0002] In recent years, the use of interventional therapy to treat vascular diseases has become a development trend. Interventional surgery usually requires a special catheter to establish a pathway, and then the catheter itself is used as an instrument to perform related surgical operations.

[0003] Generally, the catheter reaches the lesion site, the catheter seat at the tail end of the catheter is connected to the head end of the Y valve, and auxiliary instruments are introduced through the tail end of the Y valve or the side branch of the Y valve to perform relevant interventional surgery. In some cases, a switch valve is installed on the side branch of the Y valve, and the opening and closing of the side branch of the Y valve is controlled by the switch valve, such as controlling the opening and closing of the thrombus aspiration operation.

[0004] The switch valve currently used on the Y-valve side branch can only provide limited functions and a narrow scope of application, resulting in the need for frequent operations or the use of additional auxiliary instruments to complete some related interventional surgical operations. Utility Model Content

[0005] The utility model aims to design a valve and a vascular interventional surgery component to solve the problem of limited function of the existing switch valve used on the Y-valve side branch.

[0006] The utility model is realized by the following technical solutions:

[0007] The utility model provides a valve, which comprises a valve body and a valve core;

[0008] The valve body is provided with a first channel and a mounting cavity intersecting each other, and two ends of the first channel form a first fixed port and a second fixed port on the outer surface of the valve body respectively;

[0009] The valve core is rotatably and sealably inserted in the installation cavity and can be switched between a first position and a second position relative to the valve body; a first core hole and a second core hole and a third core hole respectively communicating with the first core hole are provided in the valve core, the first core hole forms a first active port and a second active port on the outer surface of the valve core, the second core hole forms a third active port on the outer surface of the valve core, and the third core hole forms a fourth active port on the outer surface of the valve core;

[0010] The valve core forms a third connection joint for detachably connecting an auxiliary device on the outer side of the fourth active port;

[0011] In the first position, the first active port and the second active port are respectively connected to the first fixed port and the second fixed port, the third active port is closed, and the fourth active port is connected to the outside;

[0012] In the second position, the first active port and the second active port are closed, the third active port is connected to the first fixed port, and the fourth active port is connected to the outside.

[0013] When the above-mentioned setting structure is adopted, the valve body provides a first channel with two ports, and the valve core simultaneously provides a first core hole, a second core hole and a third core hole that are connected to each other, and four ports are provided by the first core hole, the second core hole and the third core hole, so that no matter whether the valve core is opening the first channel or closing the first channel, the third core hole can be connected to the first fixed port of the first channel, that is, it is always connected to the environment inside the catheter.

[0014] At the same time, a third connecting connector is arranged on the outside of the fourth active port of the third core hole of the valve core, and a channel interface is reserved for other auxiliary instruments, such as needle-free connectors, Y valves, syringes, end caps, etc., to expand functions.

[0015] In this case, after the valve is installed on the Y-valve, regardless of whether the first channel of the valve body is closed or not, the auxiliary equipment connected through the third connecting joint can be connected to the environment inside the catheter and can be used at any time. In this way, more functions can be expanded based on a valve used to switch the Y-valve. When completing certain related interventional surgical operations during surgery, the use of auxiliary equipment can be reduced, and the intraoperative operation can be simplified, saving operation time and reducing intraoperative blood loss.

[0016] In order to further better implement the present invention, the following configuration structure is particularly adopted: the valve further comprises a needleless connector, and the needleless connector is detachably connected to the third connecting connector.

[0017] When the above-mentioned structure is adopted, after the third connection joint of the valve is connected to the needleless joint, the needleless joint can ensure that the fourth active port is closed when not in use, and will only be opened after the auxiliary device is connected. Therefore, on the basis of expanding the use function, it is not necessary to frequently operate to close the fourth active port, which can reduce the use of auxiliary devices, simplify the operation during surgery, save surgery time, and reduce blood loss during surgery.

[0018] In order to further better implement the present invention, the following configuration structure is particularly adopted: the needleless connector is threadedly connected to the third connecting connector.

[0019] In order to further better realize the present utility model, the following setting structure is particularly adopted: the valve core is provided with a rotating handle radially away from the third core hole.

[0020] In order to further better realize the present utility model, the following setting structure is particularly adopted: the valve body is provided with a limiting groove, the valve core is connected to a stop block located in the limiting groove, and in the first position, the stop block is circumferentially stopped at one side of the limiting groove, and in the second position, the stop block is circumferentially stopped at the other side of the limiting groove.

[0021] In order to further better realize the present invention, the following setting structure is particularly adopted: the aperture of the first core hole is larger than the apertures of the second core hole and the third core hole.

[0022] In order to better realize the present invention, the following configuration is particularly adopted: the aperture of the first core hole is equal to the aperture of the first channel.

[0023] When the above-mentioned structure is adopted, it is ensured that the passing capacity of the first core hole of the valve core is roughly consistent with the passing capacity of the first channel of the valve body, so that during the intravascular thrombus aspiration surgery, the thrombus can be better prevented from blocking the valve, and the operation of inserting and removing the catheter and repeatedly flushing can be reduced, which can save the operation time and reduce unnecessary blood loss during the operation. In addition, more operations can be performed through the valve, expanding the application scope of the valve.

[0024] In order to further better realize the present invention, the following setting structure is particularly adopted: the aperture of the first core hole is greater than or equal to 5 mm.

[0025] When the above-mentioned structure is adopted, the aperture of the first core hole is set to be no less than 5 mm, which can effectively prevent blood clots from blocking the valve and enable the valve to have a better range of application.

[0026] In order to further better realize the present utility model, the following setting structure is particularly adopted: the valve core is interference-fitted with the installation cavity, and the valve core is set as a PE material structural member.

[0027] When the above-mentioned structure is adopted, the valve core made of PE material is convenient for maintaining the sealing with the valve body while increasing the lubricity, ensuring that the force when rotating the valve core is small, and avoiding the use of silicone oil for lubrication.

[0028] In order to further better realize the present invention, the following setting structure is particularly adopted: the first core hole, the second core hole and the third core hole are perpendicular to each other and intersect at one point.

[0029] In order to further better realize the present utility model, the following configuration structure is particularly adopted: the third core hole extends along the axis of the valve core.

[0030] The utility model also provides a vascular interventional surgery component, including a catheter, a first Y-valve and the above-mentioned valve; the tail end of the catheter is connected to the head end of the first Y-valve, and the side branch of the first Y-valve is connected to the first fixed port of the valve.

[0031] In order to further better realize the present utility model, the following setting structure is particularly adopted: the vascular intervention surgery component also includes a second Y valve, and the head end of the second Y valve is used for detachable connection with the third connecting joint of the valve.

[0032] When the above-mentioned setting structure is adopted, the third connecting joint of the valve can be reserved for connection with the head end of the second Y valve, thereby expanding the function of a Y valve, so that the vascular interventional surgery component can introduce some auxiliary instruments through the tail end of the second Y valve to complete related interventional surgery operations, such as exchanging guide wires, measuring intravascular pressure, etc., so that the vascular interventional surgery component can only use a single catheter to enter the blood to perform multiple operations, which can reduce the use of auxiliary instruments such as microcatheters and pressure measuring catheters, and simplify surgical operations.

[0033] In order to better realize the present utility model, the following setting structure is particularly adopted: the valve core forms a first connection joint for detachably connecting auxiliary equipment on the outer side of the first fixed port, and the valve core forms a second connection joint for detachably connecting auxiliary equipment on the outer side of the second fixed port of the valve; the joint of the side branch pipe of the first Y valve and the first connection joint are set as hose joints, and the side branch pipe of the first Y valve is connected to the first connection joint through a first transfer tube.

[0034] The utility model has the following advantages and beneficial effects:

[0035] In the valve of the utility model, the valve body provides a first channel with two ports, and the valve core provides a first core hole, a second core hole and a third core hole that are connected to each other at the same time, and the first core hole, the second core hole and the third core hole provide four ports, so that the valve core can communicate with the first fixed port of the first channel when the first channel is opened or closed, that is, it is always connected to the environment in the catheter. At the same time, the valve core is provided with a third connecting joint on the outside of the fourth active port of the third core hole, and a channel interface is reserved for other auxiliary instruments, such as needleless connectors, Y valves, syringes, end caps, etc., to expand functions. In the vascular interventional surgery assembly on which the valve is installed on the Y valve, regardless of whether the first channel of the valve body is closed, the auxiliary instrument connected through the third connecting joint can be connected to the environment in the catheter and can be used at any time. In this way, more functions can be expanded based on a valve used to switch the Y valve. When completing certain related interventional surgery operations during surgery, the use of auxiliary instruments can be reduced, and the operation during surgery can be simplified, saving surgery time and reducing blood loss during surgery.

[0069] On the one hand, the present application provides a valve 10 that can provide more functions and has a wider range of applications, such as Figure 1 - Fig. 9 As shown, it is particularly configured as follows:

[0070] In this embodiment, the valve 10 is a rotary valve. Figure 1 As shown, it includes a valve body 11 and a valve core 12. The valve core 12 is rotatably inserted into the valve body 11 and can rotate around its own axis to open and close the flow channel. A seal is established between the valve core 12 and the valve body 11 to prevent fluid from leaking from the connection.

[0071] like Figure 1 and Figure 2 As shown, the valve body 11 is provided with an intersecting first channel 111 and an installation cavity. The first channel 111 extends straight from left to right to form a through hole, and the two ends of the first channel 111 form a first fixed port 11a and a second fixed port 11b on the outer surface of the valve body 11 respectively. The installation cavity extends straight from top to bottom to form a through hole. The valve core 12 forms a first connection joint 17 for detachably connecting auxiliary equipment on the outside of the first fixed port 11a, and the valve core 12 forms a second connection joint 18 for detachably connecting auxiliary equipment on the outside of the second fixed port 11b of the valve 10.

[0072] like Figure 3 and Figure 4As shown, the valve core 12 is provided with a first core hole 121, a second core hole 122 and a third core hole 123 which are connected to each other. Figure 4 As shown, the first core hole 121 extends linearly from left to right to form a through hole, and the two ends of the first core hole 121 form a first active port 12a and a second active port 12b on the outer peripheral surface of the valve core 12; the second core hole 122 extends horizontally in a direction perpendicular to the first core hole 121, one end of the second core hole 122 forms a third active port 12c on the outer peripheral surface of the valve core 12, and the other end is connected to the first core hole 121; the third core hole 123 extends linearly from top to bottom, the top end of the third core hole 123 forms a fourth active port 12d on the top surface of the valve core 12, and the bottom end is connected to the first core hole 121.

[0073] The first core hole 121, the second core hole 122 and the third core hole 123 are Figure 4 The layout structure shown is suitable, the first core hole 121 , the second core hole 122 and the third core hole 123 are perpendicular to each other, and one end of the second core hole 122 and the bottom end of the third core hole 123 meet at a point in the middle section of the first core hole 121 .

[0074] The valve core 12 forms a third connecting joint 13 on the outside of the fourth active port 12d located at the top, and the third connecting joint 13 is used to detachably connect auxiliary equipment. Generally, there are many common connection methods on existing auxiliary equipment. For example, some auxiliary equipment is connected to the outside through a hose, some are connected to the outside through a conventional threaded joint, and some are connected to the outside through a Luer joint. Therefore, the third connecting joint 13 can be set to different joint forms according to the different scenarios in which the valve 10 is used. Among them, one of the main application scenarios of the valve 10 of this embodiment is the vascular interventional surgery scenario. Therefore, in this embodiment, the third connecting joint 13 is preferably set to a threaded joint, so as to be able to adapt to more auxiliary equipment used in vascular interventional surgery scenarios while ensuring a greater connection force for the auxiliary equipment.

[0075] like Figure 1 and Figure 8 As shown, the valve core 12 is inserted into the valve body 11 and can rotate relative to the valve body 11 to switch between a first position and a second position.

[0076] When the valve core 12 is in the first position, Figure 2As shown, the first active port 12a and the second active port 12b are connected to the first fixed port 11a and the second fixed port 11b respectively, so that the first core hole 121 is connected to the first channel 111, and the first channel 111 is in a conducting state. At this time, the third active port 12c is opposite to the inner circumferential surface of the valve body 11, and is sealed by the seal established between the valve core 12 and the valve body 11, so that the second core hole 122 is in a closed state. At this time, the fourth active port 12d is connected to the outside, so that the third core hole 123 is in a conducting state.

[0077] When the valve core 12 is in the second position, Fig. 9 As shown, the first active port 12a and the second active port 12b rotate to the inner circumference of the valve body 11 and are sealed by the seal established between the valve core 12 and the valve body 11, so that the first channel 111 is in a closed state. At this time, the third active port 12c rotates to a position opposite to and connected with the first fixed port 11a, so that the second core hole 122 is in a conducting state. At this time, the fourth active port 12d is connected to the outside, so that the third core hole 123 is in a conducting state.

[0078] It can be seen from the above that no matter the valve core 12 is in the first position or the second position, the third core hole 123 is in a conducting state.

[0079] In this embodiment, the valve body 11 provides a first channel 111 with two ports, and the valve core 12 simultaneously provides a first core hole 121, a second core hole 122 and a third core hole 123 which are connected to each other, and four ports are provided by the first core hole 121, the second core hole 122 and the third core hole 123, so that no matter the valve core 12 is opening the first channel 111 or closing the first channel 111, the third core hole 123 can be connected to the first fixed port 11a of the first channel 111, that is, it is always connected to the environment inside the catheter.

[0080] At the same time, the valve core 12 is provided with a third connecting connector 13 on the outside of the fourth active port 12d of the third core hole 123, reserving a channel interface for other auxiliary instruments, such as a needleless connector, a Y valve, a syringe, an end cap, etc., to expand the function.

[0081] In this case, after the valve 10 is installed on the Y-valve, regardless of whether the first channel 111 of the valve body 11 is closed or not, the auxiliary equipment connected through the third connecting joint 13 can be connected to the environment inside the catheter and can be used at any time. In this way, more functions can be expanded based on a valve 10 used to switch the Y-valve. When performing certain related interventional surgical operations during surgery, the use of auxiliary equipment can be reduced, and the intraoperative operation can be simplified, saving surgical time and reducing intraoperative blood loss.

[0082] According to some optional embodiments, Figure 2and Figure 4 As shown, in the valve core 12, the third core hole 123 extends along the axis of the valve core 12, so that the position of the third core hole 123 remains unchanged during the rotation of the valve core 12 relative to the valve body 11. The first core hole 121 and the second core hole 122 extend along the radial direction of the valve core 12.

[0083] According to some optional embodiments, Figure 5 As shown, the valve 10 also includes a needleless connector 14, the bottom end of the needleless connector 14 is provided with an internal thread connector adapted to the third connecting connector 13, and the top end is provided with a connector for connecting to an auxiliary device, which can be a conventional threaded connector or a connector such as Figure 5 Luer connector shown.

[0084] like Figure 6 - Fig. 9 As shown, the needleless connector 14 is detachably connected to the third connecting connector 13 at the top of the valve core 12 through the connector at its bottom. A silicone piece is installed in the needleless connector 14, and a normally closed silicone sheet 141 is provided at the top of the silicone piece. The silicone sheet 141 functions like a one-way valve and can be opened under pressure when the needleless connector 14 is connected to other auxiliary instruments to achieve operations such as injecting liquid from outside the body into the body, and can continuously add liquid and monitor during surgery.

[0085] In this embodiment, after the third connection connector 13 of the valve 10 is connected to the needleless connector 14, the needleless connector 14 can ensure that the fourth active port 12d is closed when not in use, and will only be opened after the auxiliary device is connected. Therefore, on the basis of expanding the use function, it is not necessary to frequently operate to close the fourth active port 12d, which can reduce the use of auxiliary devices, simplify the operation during surgery, save surgery time, and reduce blood loss during surgery.

[0086] According to some optional embodiments, Figure 3 As shown, a rotary handle 15 is provided on the top of the valve core 12 to facilitate the rotation of the valve core 12. Figure 3 In the embodiment, the rotating handle 15 has two ears which are arranged radially opposite to each other. The two ears are radially away from the third core hole 123 to provide two force points for rotating the valve core 12 .

[0087] According to some optional embodiments, the valve 10 limits the position of the valve core 12 by rotating the limiting structure. Figure 6 and Figure 8As shown, a concave limit groove 112 is provided at the top edge of the valve body 11, and a stop block 16 is connected to the valve core 12, and the stop block 16 is located in the limit groove 112. When the valve core 12 rotates relative to the valve body 11, the stop block 16 rotates with the valve core 12. When the valve core 12 is in the first position, the stop block 16 circumferentially stops at one side of the limit groove 112. When the valve core 12 rotates to the second position, the stop block 16 circumferentially stops at the other side of the limit groove 112.

[0088] For example, the center angle of the limiting groove 112 is set to 90°, so that the rotation angle of the valve core 12 is 90°. When the valve core 12 is at the 0° position, Figure 6 As shown, when the valve core 12 is at the 90° position, Figure 8 shown.

[0089] According to some optional embodiments, in the valve core 12, the main function of the first core hole 121 is to switch the first channel 111 of the valve body 11, while ensuring that the first channel 111 can simultaneously pass auxiliary instruments such as guide wires while performing operations such as thrombus suction, while the second core hole 122 and the third core hole 123 generally only have the function of passing treatment instruments such as guide wires or injecting liquids, and therefore, the aperture of the first core hole 121 is generally set to be larger than the apertures of the second core hole 122 and the third core hole 123.

[0090] Preferably, the aperture of the first core hole 121 of the valve core 12 is as close as possible to the aperture of the first channel 111 of the valve body 11, for example, the aperture of the first core hole 121 is equal to the aperture of the first channel 111, so as to ensure that the passing capacity of the first core hole 121 of the valve core 12 is roughly consistent with the passing capacity of the first channel 111 of the valve body 11, so as to better prevent the thrombus from blocking the valve 10 during the intravascular thrombus aspiration surgery, reduce the need for repeated flushing of the catheter, save surgery time, and reduce unnecessary blood loss during the surgery. In addition, more operations can be performed through the valve 10, expanding the scope of application of the valve 10.

[0091] The diameter of the first core hole 121 is preferably not less than 5.0 mm, preferably 5.6 mm. When the diameter of the first core hole 121 is set to be not less than 5 mm, it can well prevent blood clots from blocking the valve 10, reduce the need for repeated flushing of the catheter, save surgical time, reduce unnecessary blood loss during surgery, and allow the valve 10 to have a better range of application.

[0092] According to some optional embodiments, the valve core 12 is sealed by interference fit with the valve body 11. Specifically, the outer peripheral surface of the valve core 12 is interference fit with the installation cavity of the valve body 11. The valve core 12 is set as a PE material structural part to increase the lubricity of the valve core 12 while maintaining the sealing with the valve body 11, so that the force when the valve core 12 rotates is small, and the operating feel is improved. In this way, it can also avoid the use of silicone oil for lubrication, which may cause silicone oil to enter the blood system, lymphatic system or lungs and cause serious health problems.

[0093] In the valve 10, the valve body 11 is formed by integral injection molding, and the valve core 12 is formed by integral injection molding, wherein the valve core 12 includes a main structure, a rotary handle 15, a stopper 16, a first connecting joint 17, a second connecting joint 18, and a third connecting joint 13. Figure 4 The third core hole 123 arranged from top to bottom as shown in the figure makes the middle of the valve core 12 have a hollowed-out design, which can effectively prevent injection shrinkage during molding, ensure the structural size, ensure sufficient interference fit with the valve body 11, and ensure good sealing. In some embodiments, the third core hole 123 extends along the axis of the valve core 12, so that the third core hole 123 is located at the center of the valve core 12, which can ensure the uniformity of the thickness of the peripheral wall of the valve core 12 without additional hollowing.

[0094] Since the third core hole 123 is located at the upper part of the valve core 12 , in order to ensure that the lower part of the valve core 12 also has good anti-shrinkage ability, a hollow portion 124 may be provided at the bottom thereof.

[0095] On the other hand, the present application provides a vascular interventional surgery assembly 100, such as Fig.10 - Fig.12 As shown, the following configuration is particularly adopted:

[0096] In this embodiment, the vascular interventional surgery component 100 uses the valve 10 in any of the above embodiments to form a set of surgical components that can be used in vascular interventional surgery, such as intravascular thrombus aspiration surgery.

[0097] like Fig.10 As shown, the vascular interventional surgery assembly 100 includes a catheter 20 , a first Y-valve 30 and a valve 10 .

[0098] The catheter 20 has a head end and a tail end, and a catheter seat 21 with a Luer connector is provided at the tail end. The first Y-valve 30 has a main pipeline and a side branch pipe, the head end of the main pipeline is provided with a Luer connector, the tail end is provided with a cock in a closed state, and the end of the side branch pipe is provided with a joint, which can be a Luer connector or a hose connector.

[0102] Preferably, Fig.12 As shown, the side branch of the second Y valve 40 is connected to a two-way valve via the Luer connector.

[0103] When the vascular interventional surgery component 100 is equipped with both the needleless connector 14 and the second Y-valve 40 , the third connecting connector 13 provided on the valve core 12 is threadedly connected to the needleless connector 14 or the second Y-valve 40 in a selective manner.

[0104] In the present embodiment, when the third connecting joint 13 provided on the valve core 12 of the valve 10 is threadedly connected to the second Y-valve 40, the function of a Y-valve is expanded, so that the vascular interventional surgery component 100 can introduce some auxiliary instruments through the tail end of the second Y-valve 40 to complete relevant interventional surgery operations, such as exchanging guide wires, measuring intravascular pressure, etc., so that the vascular interventional surgery component 100 can achieve multiple operations by only using a single catheter to enter the blood, which can reduce the use of auxiliary instruments such as microcatheters and pressure measuring catheters, and simplify surgical operations.

[0105] According to some optional embodiments, the second connecting connector 18 of the valve 10 is configured as a hose connector, to which a transparent second transfer tube 60 is connected, and the free end of the second transfer tube 60 can be connected to a negative pressure source.

[0106] Some usage scenarios of the vascular interventional surgery assembly 100 are given below:

[0107] Use Fig.10 and Fig.11 In the case of performing intravascular thrombus aspiration surgery with the vascular interventional surgery assembly 100 shown, when in use, the tail end cock of the first Y-valve 30 is in a closed state, the rotary handle 15 can be rotated 90° in advance, the valve core 12 is in the second position, the first channel 111 of the valve body 11 is closed, and then the side branch of the first Y-valve 30 is closed, and the negative pressure device is connected through the second transfer tube 60. After the negative pressure device forms a stable negative pressure, the rotary handle 15 is rotated 90° in the opposite direction, the valve core 12 is in the first position, and the side branch of the first Y-valve 30 is opened. At this time, the thrombus in the blood vessel is attracted by the negative pressure, and finally moved out of the body through the catheter 20, the side branch of the first Y-valve 30, the first transfer tube 50, the first channel 111 of the valve 10, and the second transfer tube 60, and the thrombus aspiration is completed.

[0108] Use Fig.10 and Fig.11 When the vascular interventional surgery assembly 100 shown is used for intravascular thrombus aspiration surgery, during angiography, the tail end stopcock of the first Y valve 30 is in a closed state, and the valve core 12 is in the second position by rotating the rotary handle 15, closing the first channel 111 of the valve body 11, and then closing the side branch of the first Y valve 30. At this time, the second core hole 122 of the valve core 12 is directly opposite to the side branch of the first Y valve 30 and remains connected. The syringe or angiography device with contrast agent pre-extracted is connected through the Luer connector at the top of the needleless connector 14. The Luer connector at the head end of the syringe or the angiography device squeezes and pushes open the silicone sheet 141 of the needleless connector 14, opens the needleless connector 14, and conducts the third core hole 123 of the valve core 12. The contrast agent injected by a syringe or angiography device enters the first core hole 121 through the third core hole 123 of the valve core 12, then enters the first channel 111 of the valve body 11 through the second core hole 122, and then enters the side branch of the first Y-valve 30 through the first transfer tube 50, and then reaches the target lesion through the main pipeline of the first Y-valve 30 and the catheter 20, thereby realizing the judgment of the thrombus position, the catheter position and other judgments on the intravascular conditions.

[0109] Use Fig.10 and Fig.11When the vascular interventional surgery component 100 shown is used for an intravascular thrombus aspiration surgery, when measuring the pressure in the blood vessel, the negative pressure device connected through the second transfer tube 60 can be in a closed state, and a blood pressure measuring instrument is connected to the Luer connector at the top of the needleless connector 14. At this time, the channel of the needleless connector 14 is opened, so that the third core hole 123 of the valve core 12 is in a conducting state. At this time, the pressure in the blood vessel is transmitted to the blood pressure measuring instrument through the catheter 20, the side branch of the first Y valve 30, the first channel 111 of the valve body 11, the first core hole 121 of the valve core 12, and the third core hole 123 of the valve core 12, and then measured.

[0110] Use Fig.10 and Fig.11 When the vascular interventional surgery component 100 shown is used for intravascular thrombus aspiration surgery and related auxiliary equipment such as guide wires, angiography catheters, and pressure measuring catheters need to be introduced, and the auxiliary equipment is outside the body, the needleless connector 14 is removed from the third connecting connector 13 at the top of the valve core 12 in advance, and then the vacated third connecting connector 13 is connected to the Luer at the head end of the second Y-valve 40, and then the related auxiliary equipment is introduced through the stopcock at the tail end of the second Y-valve 40.

[0111] It can be seen that during the use of the vascular interventional surgery assembly 100, the side branch of the first Y-valve 30 can be opened and closed by operating the valve 10, and the needleless connector 14 connected to the third connecting connector 13 at the top of the valve core 12 can be used to conveniently and quickly perform intraoperative drug administration, contrast agent injection, intraoperative vascular pressure monitoring, etc. And through a simple assembly process, the needleless connector 14 can be replaced with the second Y-valve 40, and then other auxiliary instruments can be introduced, so that these auxiliary instruments can smoothly enter and exit the blood vessel.

[0112] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, which should be included in the protection scope of the present invention.
