[0031] The liquid injection device 10 includes: a first injection mechanism 110, an injection pipeline 120 and a second injection mechanism 130; the first injection mechanism 110 is connected to the liquid inlet 1201 of the injection pipeline 120 to be used for injecting liquid into a set tissue through the liquid outlet 1202 of the injection pipeline 120; the second injection mechanism 130 is connected to the injection pipeline 120 through a one-way valve 101; the second injection mechanism 130 is configured to remain disconnected from the injection pipeline 120 when the first injection mechanism 110 injects liquid into the set tissue through the injection pipeline 120; and to remain connected to the injection pipeline 120 when the first injection mechanism 110 extracts liquid from the injection pipeline 120.

[0032] Therefore, both the first injection mechanism 110 and the second injection mechanism 130 provided in this embodiment can be used to set contrast fluid. When the contrast fluid contained in the first injection mechanism 110 meets the usage requirements, due to the action of the one-way valve 101, the contrast fluid in the second injection mechanism 130 will not be released; and if the contrast fluid contained in the first injection mechanism 110 is less than the usage requirements, after the contrast fluid in the first injection mechanism 110 is used up, the contrast fluid can be drawn out from the second injection mechanism 130 through the suction effect of the first injection mechanism 110 for replenishment, and the remaining contrast fluid drawn out of the second injection mechanism 130 can also be stored for next use, thereby avoiding the waste of contrast fluid.

[0033] Further reading Figure 1 and Figure 2 The injection line 120 is connected to a pressure detection device 121 for detecting the hydraulic pressure in the injection line.

[0035] In this embodiment, the liquid injection device 10 further includes a housing 140 , and the first injection mechanism 110 , the injection pipeline 120 , and the second injection mechanism 130 are all installed in the housing 140 .

[0036] The first injection mechanism 110 includes a first power mechanism 111, a first transmission rod 112 and a first syringe 113. The first power mechanism 111 includes a first power device 1111 and a screw rod 1112 connected to the first power device 1111. The screw rod 1112 is screwed to the first transmission rod 112, and the first transmission rod 112 abuts against the piston rod 1131 of the first syringe 113. Therefore, by fixing the main body of the first syringe 113 to the housing 140, the screw rod 1112 is driven to rotate by the first power device 1111, and the first transmission rod 112 can be driven to drive the piston rod 1131 of the first syringe 113 to perform linear motion, so that the piston rod 1131 can achieve the function of pushing injection or pulling liquid aspiration.

[0037] Optionally, a clamping groove 1121 is provided at the end of the first transmission rod 112 , and the end of the piston rod of the first syringe 113 is clamped in the clamping groove 1121 and fixedly connected to the first transmission rod 112 .

[0038] The second injection mechanism 130 includes a second syringe 131 and a liquid remaining amount alarm mechanism 132. The liquid remaining amount alarm mechanism 132 includes a movable trigger member 1321 and an alarm switch 1322. The movable trigger member 1321 is arranged adjacent to the second syringe 131.

[0039] Optionally, the movable trigger member 1321 is rotatably mounted on the housing 140, wherein the movable trigger member 1321 has an inclined surface on the side of the piston rod of the second syringe 131, and the end of the piston rod of the second syringe 131 moves to abut the inclined surface, thereby driving the movable trigger member 1321 to rotate in a direction away from the second syringe 131, so that the movable trigger member 1321 rotates to press against the alarm switch 1322, thereby triggering an alarm.

[0040] In this embodiment, the housing 140 includes a first housing 141 and a second housing 142. The second housing 142 is rotatably connected to the first housing 141. The first housing 141 and the second housing 142 surround a receiving space. The first injection mechanism 110 and the second injection mechanism 130 are both disposed in the receiving space. The first syringe 113 and the second syringe 131 can both be disposed in the receiving space.

[0041] In this embodiment, the second shell 142 can be used to form a rotating cover of the accommodating space.

[0042] Among them, the liquid injection device 10 also includes a third injection mechanism 150, the third injection mechanism 150 includes a third syringe 151 and a connecting tube 152, one end of the connecting tube 152 is connected to the liquid outlet of the third syringe 151, and the other end of the connecting tube 152 is used to connect with the set balloon, and the third syringe 151 is used to inject balloon liquid into the balloon through the connecting tube; wherein, the third injection mechanism 150 is installed in the accommodating space.

The power output end of the third power device 153 is connected to the piston rod of the third syringe 151. The fixed frame 155 is adjustably installed on the linear rail 154. Among them, the main body of the third syringe 151 is clamped in the fixed frame.

[0045] Therefore, by adjusting the fixed position of the fixing frame 155 on the rail 154, the third syringes 151 of different sizes can be matched. The fixing frame 155 is a frame-shaped structure, which can facilitate the overall quick plug-in and pull-out replacement of the third syringe 151.

[0046] There are two third injection mechanisms 150 , and the first injection mechanism 110 is disposed between the two third injection mechanisms 150 .

[0047] Further, based on the same inventive concept, the present application also provides a surgical imaging system, wherein the surgical imaging system includes a controller and a liquid injection device 10 as described in the above embodiment. The controller is connected to the liquid injection device 10 for controlling the liquid injection device 10.

[0048] Specifically, it can be shown that the controller is electrically connected to the driving mechanisms such as the first power device 1111 and the third power device 153 mentioned above, so that the corresponding syringes can be controlled.

[0049] In addition, the controller also includes a display screen, which can be electrically connected to the pressure detection device 121 and the alarm switch 1322 mentioned above, so that the pressure detected by the pressure detection device 121 can be displayed, and an alarm display can be performed when the alarm switch 1322 sends an alarm signal.

[0050] Optionally, a control circuit board is also provided in the liquid injection device 10, and the pressure detection device 121, the alarm switch 1322, and the first power device 1111, the third power device 153 and other driving mechanisms mentioned above are all electrically connected to the control circuit board, wherein an interface electrically connected to the control circuit board is also provided on the shell 140 of the liquid injection device 10, and the controller is electrically connected to the control circuit board through the interface.

[0051] In summary, the present application provides a liquid injection device and an angiography system for surgery. In the present application, both the first injection mechanism and the second injection mechanism can be used to set contrast liquid. When the contrast liquid in the first injection mechanism meets the dosage requirement, the contrast liquid in the second injection mechanism will not be released due to the action of the one-way valve; and if the contrast liquid in the first injection mechanism is less than the dosage requirement, after the contrast liquid in the first injection mechanism is used up, the contrast liquid can be drawn out from the second injection mechanism for replenishment through the suction action of the first injection mechanism, and the remaining contrast liquid drawn out by the second injection mechanism can also be stored for next use, thereby avoiding the waste of contrast liquid.

[0052] The above embodiments are merely illustrative of the present invention, and are not exhaustive embodiments.
