[0082] Figure 1 Schematic diagram of the structure of a surgical system in one embodiment of the present application. The surgical system includes a suction and discharge unit 100, a valve unit 200, a solvent unit 300 and a pipeline unit 400. The suction and discharge unit 100, the valve unit 200 and the solvent unit 300 are connected together through the pipeline unit 400. The pipeline unit 400 includes a plurality of pipelines, and the valve unit 200 can be used as a central unit to connect the suction and discharge unit 100 and the solvent unit 300 respectively through different pipelines. The valve unit 200 is used to control the opening and closing of each pipeline of the pipeline unit 400 to control the connection and blocking of the suction and discharge unit 100 and the solvent unit 300, thereby realizing the exhaust action and solvent injection action of the surgical system.

[0083] In one embodiment, the pipeline unit 400 includes a plurality of pipelines, one of which connects the solvent unit 300 and the valve unit 200, another pipeline connects the valve unit 200 and the suction and discharge unit 100, and another pipeline has one end connected to the valve unit 200 and the other end used to connect to the blood vessel. In this embodiment, the valve unit 200 can be used as a central unit, and the suction and discharge unit 100 and the solvent unit 300 are respectively connected through different pipelines.

[0084] In one embodiment, the suction and discharge unit 100 includes a suction and discharge assembly 150 and a driving assembly 160 . The driving assembly 160 is used to provide power to the suction and discharge assembly 150 so that the suction and discharge assembly 150 can suck the medium from the outside or discharge the medium stored in the suction and discharge assembly 150 .

[0085] Figure 2FIG. 1 is a schematic diagram of the structure of a suction and discharge assembly 150 in an embodiment. The suction and discharge assembly 150 includes a housing 130 having a storage chamber 120, and also includes a control member 140 that can move in the storage chamber 120 to change the effective storage space of the storage chamber 120, and a drive assembly 160 is used to drive the control member 140 to move relative to the storage chamber 120. Figure 2 When the driving component 160 drives the control component 140 to move upward, the effective storage space of the storage chamber 120 increases, so that the suction and discharge component 150 can draw the medium from the outside; wherein, the effective storage space of the storage chamber 120 is used to store the medium drawn from the outside; when the driving component 160 drives the control component 140 to move downward, the effective space of the storage chamber 120 decreases, and the suction and discharge component 150 can discharge the medium stored therein.

[0086] The valve unit 200 is used to control whether the solvent unit 300, the valve unit 200, the suction and discharge unit 100, and the pipeline unit 400 used to connect the three are interconnected. When the pipeline unit 400 also includes a pipeline that is not connected to the above three, the valve unit 200 in this embodiment can at least control whether the part of the pipeline unit 400 used to connect the three is interconnected.

[0087] The solvent unit 300, valve unit 200, suction and discharge unit 100 and the pipe unit 400 for connecting the three form a subsystem, and the gas in the subsystem is extracted by the suction and discharge unit 100. Specifically, the gas in the subsystem is sucked away by the suction and discharge unit 100, and at the same time, the suction and discharge unit 100 also sucks a part of the solvent in the solvent unit 300, so that the part of the pipe unit 400 in the subsystem is filled with solvent, thereby realizing the exhaust process. After the exhaust process is completed, the gas in the solvent unit 300, the part of the valve unit 200, and the pipe unit 400 in the subsystem are all sucked into the valve unit 200.

[0088] Furthermore, the valve unit 200 can also control the pipeline between the valve unit 200 and the solvent unit 300 to be blocked, so that the solvent unit 300 is no longer connected to the valve unit 200 and the suction and discharge unit 100. The valve unit 200 controls the pipeline used to connect the blood vessel to be opened, and connects the pipeline to the suction and discharge unit 100 through the valve unit 200. Since a part of the solvent sucked from the solvent unit 300 is stored in the suction and discharge unit 100 after the above-mentioned exhaust process, the solvent can be discharged into the pipeline used to connect to the blood vessel, thereby exhausting the gas in the pipeline. In this process, the pipeline used to connect the blood vessel is not connected to the blood vessel first, and the blood vessel is connected after the gas in the pipeline is exhausted.

[0089] Furthermore, the valve unit 200 can also control the pipe connecting the valve unit 200 and the suction and discharge unit 100 to be blocked, so that the suction and discharge unit 100 is no longer connected to the valve unit 200. The valve unit 200 controls the solvent unit 300 to be connected to the pipe used to connect the blood vessel, so that the solvent can be injected into the blood vessel through the solvent unit 300.

[0090] In another embodiment, the suction and discharge unit 100 can be connected to the solvent unit 300 by controlling the valve unit 200, so that the suction and discharge unit 100 first absorbs the solvent in the solvent unit 300, and then is blocked from the solvent unit 300 and connected to the pipeline connected to the blood vessel, so as to inject the absorbed solvent into the blood vessel, thereby utilizing the suction and discharge unit 100 to achieve rapid and high-flow injection of solvent into the blood vessel.

[0091] In the above-mentioned surgical system, the pipeline unit 400 includes at least two sections, one of which is located between the solvent unit 300 and the suction and discharge unit 100, and the gas in the section can be sucked away by the suction and discharge unit 100; and the pipeline unit 400 also includes at least one section that is not located between the solvent unit 300 and the suction and discharge unit 100, and the gas in the section is discharged through the part of the solvent sucked from the solvent unit 300 stored in the suction and discharge unit 100. Therefore, the exhaust in at least two sections of the pipeline unit 400 is achieved by the suction and discharge capabilities of the suction and discharge unit 100. The surgical system has the advantages of simple operation and convenient exhaust. In addition, the solvent in the solvent unit 300 can be directly injected into the blood vessel in a natural dripping manner through the control of the valve unit 200 to achieve slow injection, or the solvent in the solvent unit 300 can be sucked by the suction and discharge unit 100 first, and then the solvent can be quickly injected into the blood vessel using the large power of the suction and discharge unit 100 with an independent drive component 160 to achieve rapid injection of the solvent unit 300. The surgical system can selectively implement slow injection and fast injection of the solvent.

[0092] Specifically, the control member 140 and the housing 130 are sealed to form a seal between the storage chamber 120 and the outside. The housing 130 is provided with a passage opening 110 connected to the storage chamber 120, and the control member 140 can move in the storage chamber 120, so that positive pressure or negative pressure is formed in the storage chamber 120. When the control member 140 moves relative to the housing 130 to reduce the effective storage space of the storage chamber 120, a positive pressure is formed in the storage chamber 120, and the medium in the storage chamber 120 can be discharged through the passage opening 110. When the control member 140 moves relative to the housing 130 to increase the effective space of the storage chamber 120, a negative pressure is formed in the storage chamber 120, and the medium in the storage chamber 120 can be sucked into the storage chamber 120 through the passage opening 110. For example, the storage cavity 120 may be cylindrical, the control member 140 may also be cylindrical, the cylindrical outer wall of the control member 140 is attached to the cylindrical inner wall of the storage cavity 120, and the control member 140 may slide along the cylindrical storage cavity 120. For another example, the storage cavity 120 and the control member 140 may also be in other shapes, such as a triangular prism, a quadrangular prism, or a pentagonal prism.

[0093] In one embodiment, the channel opening 110 is located below the storage chamber 120, so that gases such as air and liquids such as solvents stored in the storage chamber 120 will be deposited below. When the control member 140 slides downward, the liquid will be discharged from the channel opening 110 first, while the gas will remain in the storage chamber 120.

[0094] In one embodiment, the suction and discharge unit 100 is detachably connected to the pipeline unit 400. For example, the channel port 110 of the suction and discharge unit 100 is detachably connected to the pipeline unit 400. In the above embodiment, the gas in the pipeline is discharged by discharging part of the solvent sucked from the solvent unit 300 stored in the suction and discharge unit 100 into the pipeline used to connect the blood vessels. Since a part of the gas is still stored in the suction and discharge unit 100, the suction and discharge unit 100 is disassembled from the pipeline unit 400, the control member 140 is slid toward the channel port 110 and the medium in the storage chamber 120 is emptied, and then the channel port 110 is connected to the suction and discharge pipeline 430, so that the gas in the suction and discharge unit 100 is discharged, and the gas in the entire surgical system has been discharged.

[0095] Figure 3 1 is a schematic diagram of the structure of a suction and discharge unit 100 in an embodiment. The suction and discharge unit 100 includes a driving assembly 160 and a suction and discharge assembly 150. The suction and discharge assembly 150 is mounted on the driving assembly 160. The driving assembly 160 includes a base 161, a mounting seat 164 and a driving block 163. The mounting seat 164 is fixedly connected to the base 161. The driving block 163 is slidably connected to the base 161. The driving block 163 can slide linearly relative to the mounting seat 164. Figure 2 and Figure 3The shell 130 of the suction and discharge assembly 150 is installed on the mounting seat 164, and the control member 140 of the suction and discharge assembly 150 is installed on the driving block 163. The driving block 163 is used to drive the control member 140 to move linearly relative to the shell 130, thereby changing the volume of the storage chamber 120.

[0096] Figure 4 1 is a schematic diagram of the structure of a driving assembly 160 in an embodiment, wherein the driving assembly 160 includes a driving member 162 and a transmission member 165, wherein the transmission member 165 is used to connect the driving member 162 and the driving block 163, thereby moving the driving block 163. The driving member 162 can be fixedly mounted on the base 161, and the driving member 162 is, for example, a motor, and the output shaft of the motor is connected to the transmission member 165, and the transmission member 165 can convert the rotation of the motor into the linear motion of the driving block 163.

[0097] In one embodiment, Figure 4 As shown, the transmission component 165 includes a screw rod 1651, a sliding seat 1652 and a guide rail 1653. The guide rail 1653 is fixedly connected to the base 161. The sliding seat 1652 includes a sliding connection portion 16521 that slides with the catheter. The sliding seat 1652 is also provided with a threaded hole, and the screw rod 1651 is inserted into the threaded hole. The output shaft of the driving member 162 is used to connect the screw rod 1651, thereby driving the screw rod 1651 to rotate. The screw rod 1651 is rotatably connected to the base 161, and the axial movement of the screw rod 1651 is limited by the base 161. Therefore, when the driving member 162 drives the screw rod 1651, the screw rod 1651 can only rotate relative to the base 161 but cannot move. When the screw rod 1651 rotates, it can drive the sliding seat 1652 to move along the catheter. Figure 4 Slide direction shown is linear motion.

[0098] Of course, in some embodiments, there may be components such as gears between the screw rod 1651 and the driving member 162 for changing the transmission direction.

[0099] In the above embodiment, the suction and discharge unit 100 can be disassembled by making the suction and discharge unit 100 detachably connected to the pipeline unit 400, so that the gas or a single solvent or a mixed solvent in the suction and discharge unit 100 can be discharged separately without being discharged into the pipeline unit 400. Since the suction and discharge unit 100 includes the suction and discharge assembly 150 and the drive assembly 160, in one embodiment, the entire suction and discharge unit 100 can be detachably connected to the pipeline unit 400; in another embodiment, the suction and discharge assembly 150 and the pipeline unit 400 can be detachably connected separately, and the suction and discharge assembly 150 is also detachably connected to the drive assembly 160. The suction and discharge assembly 150 and the pipeline unit 400 can be detachably connected by making the channel port 110 and the pipeline unit 400 detachable, and the following example illustrates the manner in which the suction and discharge assembly 150 and the drive assembly 160 are detachable.

[0100] Figure 5 FIG. 1 is a schematic diagram of the structure of a driving assembly 160 according to an embodiment of the present invention. The driving assembly 160 includes a driving block 163 and a mounting seat 164 .

[0101] In one embodiment, the mounting seat 164 is used to connect the housing 130 of the suction and discharge assembly 150, and the driving block 163 is used to connect the control member 140 of the suction and discharge assembly 150. Then, the mounting seat 164 can be detachably connected to the housing 130, and the driving block 163 can be detachably connected to the control member 140.

[0102] In one embodiment, the mounting seat 164 can be used to connect the control member 140 of the suction and discharge assembly 150, and the driving block 163 is used to connect the housing 130 of the suction and discharge assembly 150. At this time, the mounting seat 164 can be detachably connected to the control member 140, and the driving block 163 can be detachably connected to the housing 130.

[0103] like Figure 5 As shown, the driving block 163 is provided with a first mounting groove 1631, and the mounting seat 164 is provided with a second mounting groove 1641. The sliding directions of the driving block 163 and the mounting seat 164 are as shown in FIG. Figure 5 The first mounting groove 1631 and the second mounting groove 1641 are card slot structures, and the card slot is oriented to the side, so that the parts installed in the first mounting groove 1631 and the second mounting groove 1641 are inserted into the first mounting groove 1631 or the second mounting groove 1641 in a direction perpendicular to or at an acute angle to the sliding direction, and will not be separated from the card slot when sliding along the sliding direction.

[0104] When the mounting seat 164 is used to connect the shell 130 of the suction and exhaust assembly 150 and the driving block 163 is used to connect the control component 140 of the suction and exhaust assembly 150, the first mounting groove 1631 is used to accommodate at least a portion of the control component 140 so that the driving block 163 and the control component 140 are detachably fixedly connected, and the second mounting groove 1641 is used to accommodate at least a portion of the shell 130 so that the mounting seat 164 and the shell 130 are detachably fixedly connected.

[0105] When the mounting seat 164 is used to connect the control member 140 of the suction and discharge assembly 150, and the driving block 163 is used to connect the housing 130 of the suction and discharge assembly 150,

[0106] The first mounting groove 1631 is used to accommodate at least a portion of the shell 130 so that the driving block 163 is detachably fixedly connected to the shell 130 . The second mounting groove 1641 is used to accommodate at least a portion of the control member 140 so that the mounting seat 164 is detachably fixedly connected to the control member 140 .

[0110] During the solvent injection operation, the valve unit 200 can be used to control the solvent unit 300 to communicate with the main pipeline 410 through the device pipeline 420, so that the solvent in the solvent unit 300 flows into the blood vessel.

[0111] Of course, in other embodiments, when the solvent is in action, the solvent in the solvent unit 300 may be first sucked out by the suction and discharge assembly 150, and then the solvent may be injected into the blood vessel through the main pipeline 410 by the suction and discharge unit 100, and this process is realized by controlling the connection of different pipelines by the valve unit 200. Specifically, when the solvent is injected, the valve unit 200 is used to control the connection between the equipment pipeline 420 and the suction and discharge pipeline 430, and the suction and discharge unit 100 is used to suck the solvent in the solvent unit 300; the valve unit 200 is also used to control the connection between the suction and discharge pipeline 430 and the main pipeline 410, and the suction and discharge unit 100 is used to discharge the stored solvent through the main pipeline 410.

[0115] In one embodiment, the three valve pipelines are arranged perpendicularly to each other, and the three inner channels are also arranged perpendicularly. In other embodiments, the three valve pipelines can also be arranged at other angles, and the angles of the three inner channels are arranged correspondingly to the angles of the three valve pipelines.

[0121] like Figure 8 As shown, the valve core of the valve unit 200 is Figure 7a The solvent unit 300 is now connected to the suction and discharge unit 100. When the suction and discharge unit 100 is suctioning, the gas and a part of the solvent in the solvent unit 300 enter the suction and discharge unit 100 along the shaded path in the figure through the equipment pipeline 420, the valve unit 200 and the suction and discharge pipeline 430, and at the same time, the air in the shaded path is also sucked into the suction and discharge unit 100.

[0122] like Fig. 9 As shown, the valve core of the valve unit 200 is Figure 7b The state shown. At this time, the main pipeline 410 is connected to the suction and discharge pipeline 430, and the equipment pipeline 420 is blocked from the main pipeline 410 and the suction and discharge pipeline 430. At this time, the part of the solvent stored in the suction and discharge unit 100 can be discharged into the main pipeline 410 and discharged from the other end of the main pipeline 410. As a result, the air in the part of the valve unit 200 and the main pipeline 410, that is, the air in the shaded path in the figure, is discharged.

[0123] like Fig.10 As shown, the valve core of the valve unit 200 is Figure 7c At this time, the device pipeline 420 is connected to the main pipeline 410, and the suction and discharge pipeline 430 is blocked from both the main pipeline 410 and the device pipeline 420. The solvent unit 300 is connected to the main pipeline 410 through the device pipeline 420. When the main pipeline 410 is connected to the blood vessel, the solvent can be injected into the blood vessel through the solvent unit 300. Of course, it is also possible to first Figure 8 In the state shown, the solvent is sucked from the solvent unit 300 by the suction unit 500, and then Fig. 9 In the state shown, the solvent sucked by the suction unit 500 is rapidly injected into the blood vessel.

[0124] Fig.11 FIG. 1 is a schematic diagram of the structure of a surgical system in one embodiment. Figure 1On the basis of the surgical system shown, the solvent unit 300 includes a first solvent device 310 and a second solvent device 320, and the equipment pipeline 420 includes a first pipeline 421 and a second pipeline 422; the first pipeline 421 connects the first solvent device 310 and the valve unit 200, and the second pipeline 422 connects the second solvent device 320 and the valve unit 200. The suction and discharge unit 100 is used to suck the gas and / or at least a part of the solvent in the first solvent device 310 and the second solvent device 320 in sequence.

[0125] Fig.12 for Fig.11 The schematic diagram of the structure of the valve unit 200 in the surgical system in the embodiment shown, the valve unit 200 includes two valve assemblies 210, and the two valve assemblies 210 are connected in series, and the series connection mode is that the first valve pipeline 221 in the valve assembly 210 on the left is used to connect the third valve pipeline 223 of the valve assembly 210 on the right. The first valve pipeline 221 of the valve assembly 210 on the right is connected to the suction and discharge pipeline 430, and the third valve pipeline 223 in the valve assembly 210 on the left is connected to the main pipeline 410. The second valve pipeline 222 in the valve assembly 210 on the left is used to connect the first solvent device 310 through the first pipeline 421. The second pipeline in the valve assembly 210 on the right is used to connect the second solvent device 320 through the second pipeline 422.

[0126] Among them, the valve unit 200 is used to control the on-off of the pipeline unit 400; when the suction and discharge unit 100 is in a state of sucking the gas and / or at least a part of the solvent in the first solvent device 310, the valve unit 200 enables the first pipeline 421 and the suction and discharge pipeline 430 to be connected, and the second pipeline 422 is isolated from the suction and discharge pipeline 430; when the suction and discharge unit 100 is in a state of sucking the gas and / or at least a part of the solvent in the second solvent device 320, the valve unit 200 enables the second pipeline 422 and the suction and discharge pipeline 430 to be connected, and the first pipeline 421 is isolated from the suction and discharge pipeline 430.

[0127] Fig.13 FIG. 1 is a schematic diagram of the structure of a surgical system in one embodiment. Fig.11 On the basis of the surgical system shown, the surgical system further includes a suction unit 500 , and the pipeline unit 400 further includes a third pipeline 423 , and the third pipeline 423 connects the solvent unit 300 and the valve unit 200 .

[0128] Fig.14 for Fig.13The schematic diagram of the structure of the valve unit 200 in the surgical system in the embodiment shown, the valve unit 200 includes three valve assemblies 210, and the three valve assemblies 210 are connected in series. The interfaces of the three valve pipelines of each valve assembly 210 for connecting with external pipelines are valve ports of the corresponding valve pipelines. The first pipeline 421, the second pipeline 422, the third pipeline 423, the suction and discharge pipeline 430 and the main pipeline 410 are respectively connected to different valve ports.

[0129] Specifically, among the three valve assemblies 210 connected in series, the third valve pipeline 223 of the valve assembly 210 in the middle is connected to the first valve pipeline 221 of the valve assembly 210 on the left, and the first valve pipeline 221 of the valve assembly 210 in the middle is connected to the third valve pipeline 223 of the valve assembly 210 on the right. The valve port of the third valve pipeline 223 of the valve assembly 210 on the left is connected to the main pipeline 410. The valve port of the first valve pipeline 221 of the valve assembly 210 on the right is connected to the suction and discharge pipeline 430. The valve port of the second valve pipeline 222 of the valve assembly 210 on the left is connected to the first pipeline 421, the valve port of the second valve pipeline 222 of the valve assembly 210 in the middle is connected to the second pipeline 422, and the valve port of the second valve pipeline 222 of the valve assembly 210 on the right is connected to the third pipeline 423.

[0130] In some embodiments, the valve unit 200 can independently control the first pipe 421 to connect with the suction and exhaust pipe 430, the first pipe 421 to connect with the main pipe 410, or the second pipe 422 to connect with the suction and exhaust pipe 430, or the second pipe 422 to connect with the main pipe 410, or the third pipe 423 to connect with the suction and exhaust pipe 430, or the third pipe 423 to connect with the main pipe 410.

[0131] Figures 15 to 20 for Fig.13 The schematic diagrams of six different working states of the surgical system in the illustrated embodiment are as follows: the surgical system is illustrated by taking the first solvent device 310 for imaging, the second solvent device 320 for dripping, and the suction unit 500 for suctioning thrombus as examples.

[0132] like Fig.15 As shown, the valve unit 200 includes three valve cores, all of which are Figure 7aThe state shown. At this time, the first solvent device 310 for contrast imaging is connected to the suction and discharge unit 100. The second solvent device 320 for dripping is blocked from the suction and discharge unit 100, and the suction unit 500 for aspirating thrombus is also blocked from the suction and discharge unit 100. When the suction and discharge unit 100 performs suction, the gas in the first solvent device 310 and a part of the contrast agent are sucked into the suction and discharge unit 100 along the shaded path in the figure through the first pipeline 421, part of the valve unit 200 and the suction and discharge pipeline 430, and the air in the shaded path is also sucked into the suction and discharge unit 100.

[0133] like Fig.16 As shown, among the three valve cores, the valve core on the far right is Figure 7b The state shown, while the middle valve core and the leftmost valve core are Figure 7a The state shown. At this time, the first solvent device 310 for contrast imaging is blocked from the suction and discharge unit 100, and the suction unit 500 for suction is also blocked from the suction and discharge unit 100. The second solvent device 320 for instillation is connected to the suction and discharge unit 100. The suction and discharge unit 100 continues to suction, and the gas in the second solvent device 320 and a part of the physiological saline are sucked into the suction and discharge unit 100 along the shaded path in the figure through the second pipe 422, part of the valve unit 200 and the suction and discharge pipe 430, and the air in the shaded path is also sucked into the suction and discharge unit 100.

[0134] exist Fig.15 and Fig.16 In the embodiment shown, the gas in the first solvent device 310, the first pipeline 421, the second solvent device 320 and the second pipeline 422 is exhausted, and this part of the gas is stored in the suction and discharge unit 100, and the mixed solution of contrast agent and physiological saline is also stored in the suction and discharge unit 100. In the following steps, the gas in the rest of the pipeline unit 400 is exhausted using the mixed solution.

[0135] like Fig.17 As shown, all three valve cores are Figure 7b The state shown. At this time, the first solvent device 310 for contrast imaging, the second solvent device 320 for instillation, and the suction unit 500 for aspirating thrombus are all blocked with the valve unit 200, and the suction and discharge unit 100 is connected with the main pipeline 410 through the valve unit 200. At this time, the suction and discharge unit 100 discharges the mixed solution of contrast agent and physiological saline stored therein into the part of the valve unit 200 and the main pipeline 410, and discharges it from the other end of the main pipeline 410. As a result, the air in the part of the valve unit 200 and the main pipeline 410, that is, the air in the shaded path in the figure, is discharged.

[0136] After this step, the suction and discharge unit 100 may be separated from the suction and discharge pipeline 430 , and after the gas and the remaining mixed solution in the suction and discharge unit 100 are discharged, the suction and discharge unit 100 may be connected to the suction and discharge pipeline 430 again.

[0137] When contrast medium needs to be injected into the blood vessels, the surgical system can be placed in Fig.15 In the state shown, the contrast medium in the first solvent device 310 is sucked out by the suction and discharge unit 100. Then the surgical system is in Fig.17 In the state shown, the suction and discharge unit 100 discharges the sucked contrast agent into the blood vessel through the main pipeline 410. This method can utilize the large suction force of the suction and discharge unit 100 to quickly discharge the contrast agent into the blood vessel, thereby preventing the contrast agent from being diluted by the blood flow and causing poor observation effect.

[0138] like Fig.18 As shown in the figure, among the three valve cores, the valve core on the far right and the valve core in the middle are Figure 7c The valve core on the far left is Figure 7b The state shown. At this time, the second solvent device 320 for instillation is connected to the main pipeline 410. The first solvent device 310 for angiography is blocked from the main pipeline 410, the suction unit 500 for aspirating thrombus is also blocked from the main pipeline 410, and the suction and discharge unit 100 is also blocked from the main pipeline 410. Physiological saline can be injected into the blood vessel through the main pipeline 410 through the second solvent device 320, that is, instillation is performed. Since the instillation process is relatively slow, the physiological saline can be naturally instilled only through the second solvent device 320 without the need for rapid injection through the suction and discharge unit 100.

[0139] like Fig.19 As shown, all three valve cores are Figure 7c At this time, the suction unit 500 for aspirating thrombus is connected to the main pipeline 410. The first solvent device 310 for angiography is blocked from the main pipeline 410, the second solvent device 320 for instillation is blocked from the main pipeline 410, and the suction and discharge unit 100 is also blocked from the main pipeline 410. The suction unit 500 may, for example, include a suction pump with an independent suction function, and the thrombus is aspirated from the blood vessel through the suction and discharge unit 100 through the main pipeline 410.

[0140] Of course, in other embodiments, if the first solvent device 310 is also used for dripping, it does not need to be quickly injected through the suction and discharge unit 100, so that the surgical system can be in a state of Fig. 20 Status shown.

[0141] like Fig. 20 As shown, among the three valve cores, the valve core on the far right is Figure 7c The state shown, while the middle valve core and the leftmost valve core are Figure 7b At this time, the first solvent device 310 is connected to the main pipeline 410, while the suction and discharge unit 100 is blocked from the main pipeline 410, the second solvent device 320 is blocked from the main pipeline 410, and the suction unit 500 is also blocked from the main pipeline 410. Natural infusion can be performed into the blood vessel through the first solvent device 310 through the main pipeline 410.

[0142] One embodiment of the present application provides a method for using a surgical system, including an exhaust step:

[0143] S100, the suction and discharge unit 100 sucks and stores the gas and / or at least a portion of the solvent in the equipment pipeline 420 connected between the suction and discharge unit 100 and the solvent unit 300, and sucks and stores the gas and / or at least a portion of the solvent in the solvent unit 300, so that the equipment pipeline 420 is filled with the solvent;

[0144] S200 , closing the passage between the equipment pipeline 420 and the main pipeline 410 , discharging at least a portion of the solvent stored in the suction and discharge unit 100 into the main pipeline 410 , so as to discharge the gas in the main pipeline 410 .

[0145] In one embodiment, step S100 further includes step S101, connecting the first pipe 421 with the suction and discharge pipe 430, and sucking the gas and at least a portion of the solvent in the first solvent device 310 through the suction and discharge unit 100 to fill the first pipe 421 with the solvent.

[0146] like Fig.15 As shown, the first solvent device 310 is connected to the suction and discharge unit 100, while the second solvent device 320 and the suction unit 500 are blocked from the suction and discharge unit 100. Specifically, the first pipe 421 is connected to the suction and discharge pipe 430, while the second pipe 422 and the third pipe 423 are blocked from the suction and discharge pipe 430. The suction and discharge unit 100 sucks and stores the gas and / or at least a portion of the solvent in the equipment pipe 420 connected between the suction and discharge unit 100 and the first solvent device 310. It can be understood that if the solvent initially exists in the equipment pipe 420, the solvent in the equipment pipe 420 can also be sucked into the suction and discharge unit 100. At the same time, the gas and / or at least a portion of the solvent in the first solvent device 310 are sucked and stored by the suction and discharge unit 100, so that the equipment pipe 420 is filled with solvent. At this time, the gas in the equipment pipe 420, the gas in the first solvent device 310, and the gas in the part of the valve unit 200 connected between the first pipe 421 and the suction and discharge pipe 430 are all sucked away.

[0148] like Fig.16 As shown, the second solvent device 320 is connected to the suction and discharge unit 100, while the first solvent device 310 and the suction unit 500 are blocked from the suction and discharge unit 100. The suction and discharge unit 100 sucks and stores the gas and / or at least a portion of the solvent in the equipment pipeline 420 connected between the suction and discharge unit 100 and the second solvent device 320. At the same time, the suction and discharge unit 100 sucks and stores the gas and / or at least a portion of the solvent in the second solvent device 320, so that the equipment pipeline 420 is filled with solvent. At this time, the gas in the equipment pipeline 420, the gas in the second solvent device 320, and the gas in the part of the valve unit 200 connected between the second pipeline 422 and the suction and discharge pipeline 430 are all sucked away.

[0149] In one embodiment, when the surgical system includes a solvent unit 300 but does not include a suction unit 500, step S100 further includes step S103A located after step S102, closing the connection between the first pipeline 421 and the second pipeline 422 and the suction and discharge pipeline 430, connecting the suction and discharge pipeline 430 with the main pipeline 410, and discharging the solvent into the main pipeline 410 through the suction and discharge unit 100 to discharge the gas in the main pipeline 410.

[0150] like Fig. 9 As shown, the passage between the equipment pipeline 420 (the first pipeline 421 and the second pipeline 422) and the main pipeline 410 is closed.
