[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0032] The inventor of the present application has found that, if it is necessary to establish pneumoperitoneum during an operation and to use a surgical electrode with flushing, the required equipment includes at least a pneumoperitoneum machine, an electrode host, and a negative pressure aspirator. The pneumoperitoneum machine plays the role of establishing pneumoperitoneum and exhausting smoke, and the surgical electrode with flushing requires an external negative pressure aspirator to play the role of flushing and waste liquid recovery. However, in fact, the pneumoperitoneum machine can also play the role of a negative pressure aspirator. Using a pneumoperitoneum machine and a negative pressure aspirator at the same time will cause a waste of surgical instrument resources, and the more instruments there are, the more operations are required, and the risk of misoperation will increase. The embodiments of the present application provide a pneumoperitoneum machine pipeline system, which is at least used to solve the above-mentioned technical problems.

[0033] Please refer to Figure 1-Figure 5 The pneumoperitoneum machine pipeline system provided in the embodiment of the present application includes a pneumoperitoneum machine 1, a filter 2, a smoke evacuation puncture device 3, a liquid storage bag 4, a waste liquid bag 5, a first pipeline group, a second pipeline group and an electrode assembly. The pneumoperitoneum machine 1 is connected to the filter 2, the filter 2 is connected to the electrode assembly through the first pipeline group, and the filter 2 is connected to the smoke evacuation puncture device 3 through the second pipeline group. The liquid storage bag 4 and the waste liquid bag 5 are both connected to the first pipeline group. The liquid storage bag 4 is used to store cleaning liquid, and the waste liquid bag 5 is used to collect waste liquid.

[0034] It should be pointed out that the filter 2 is connected to the first pipeline group, the first pipeline group is connected to the electrode assembly, and the filter 2 is connected to the second pipeline group, the second pipeline group is connected to the smoke exhaust puncture device 3, and the cleaning liquid stored in the liquid storage bag 4 is physiological saline. Of course, it can also be other liquids that can be used for debridement, and there is no limitation on this.

[0035] During the operation of the pneumoperitoneum machine pipeline system, the electrode assembly cuts a wound, and under the action of the air pressure (positive pressure or negative pressure) of the pneumoperitoneum machine 1, the cleaning liquid in the liquid storage bag 4 cleans the wound through the first pipeline group and the electrode assembly, and the waste liquid generated by the cleaning flows into the waste liquid bag 5 through the first pipeline group for collection; in addition, the pneumoperitoneum machine 1 can send carbon dioxide into the abdominal cavity through the filter 2, the second pipeline group and the smoke exhaust puncture device 3 in sequence to establish pneumoperitoneum and maintain a constant pressure state. The smoke generated by the electrode assembly can also be discharged from the body through the smoke exhaust puncture device 3, the second pipeline group, the filter 2, and the pneumoperitoneum machine 1 in sequence, ensuring a clear surgical field of view. The entire pneumoperitoneum machine pipeline system does not require a negative pressure suction device, which reduces the waste of surgical instrument resources and reduces the risk of misoperation.

[0036] In this embodiment, the first pipeline group includes a flushing tube 6 and a suction tube 7, the pneumoperitoneum machine pipeline system also includes a first connecting valve 8 and a second connecting valve 9, the filter 2 is provided with a first air inlet pipe 21 and a first exhaust pipe 22, the first air inlet pipe 21 and the flushing tube 6 are both connected to the first connecting valve 8, the first exhaust pipe 22 and the suction tube 7 are both connected to the second connecting valve 9, the liquid storage bag 4 is arranged on the flushing tube 6 and is connected to the flushing tube 6, and the waste liquid bag 5 is arranged on the suction tube 7 and is connected to the suction tube 7.

[0037] The first connecting valve 8 and the second connecting valve 9 are both one-inlet and two-outlet valves. The first air inlet pipe 21 is connected to the first end of the first connecting valve 8, the first air outlet pipe 22 is connected to the first end of the second connecting valve 9, and the flushing pipe 6 and the suction pipe 7 are connected to the second end of the first connecting valve 8 and the second end of the second connecting valve 9 respectively.

[0038] After the electrode assembly cuts the wound, under the action of the air pressure of the pneumoperitoneum machine 1, the cleaning liquid in the liquid storage bag 4 cleans the wound through the flushing tube 6 and the electrode assembly, and the waste liquid generated by the cleaning flows into the waste liquid bag 5 through the suction tube 7 for collection.

[0039] The flushing pipe 6 includes a horizontal first flushing pipe section 61 and a bent second flushing pipe section 62. The first flushing pipe section 61 is connected to the second end of the first connecting valve 8, and the second flushing pipe section 62 is connected to the electrode assembly. The liquid storage bag 4 is connected between the first flushing pipe section 61 and the second flushing pipe section 62. The first flushing pipe section 61 is connected to the side of the liquid storage bag 4, and the second flushing pipe section 62 is connected to the bottom of the liquid storage bag 4, so that the cleaning liquid in the liquid storage bag 4 can flow toward the electrode assembly. The suction pipe 7 includes a horizontal first suction pipe section 71 and a bent second suction pipe section 72. The second suction pipe segment 72 is bent, the first suction pipe segment 71 is connected to the electrode assembly, the second suction pipe segment 72 is connected to the second end of the second connecting valve 9, the waste liquid bag 5 is connected between the first suction pipe segment 71 and the second suction pipe segment 72, the first suction pipe segment 71 is connected to the side of the waste liquid bag 5, and the second suction pipe segment 72 is connected to the top surface of the waste liquid bag 5, so that the waste liquid flowing into the waste liquid bag 5 from the first suction pipe segment 71 is not easy to enter the second suction pipe segment 72, so as to prevent the waste liquid from directly flowing into the pneumoperitoneum machine 1 through the second suction pipe segment 72.

[0040] The waste liquid bag 5 is a roughly rectangular transparent bag body, and a liquid level line is provided on the waste liquid bag 5 . When the liquid level in the waste liquid bag 5 exceeds the liquid level line, the waste liquid bag 5 can be replaced to prevent the waste liquid from entering the pneumoperitoneum machine 1 .

[0041] In this embodiment, the pneumoperitoneum machine pipeline system also includes a third connecting valve 10, one end of the flushing tube 6 away from the first connecting valve 8 is connected to the third connecting valve 10, and one end of the suction tube 7 away from the second connecting valve 9 is connected to the third connecting valve 10. The electrode assembly includes a metal tube 11 and an electrode head 12. One end of the metal tube 11 is connected to the third connecting valve 10, and the other end of the metal tube 11 is provided with the electrode head 12.

[0042] The third connecting valve 10 is a two-inlet-one-outlet valve, the first end of which is connected to the metal pipe 11, and the second end and the third end of the two-inlet-one-outlet valve are respectively connected to the second flushing pipe section 62 of the flushing pipe 6 and the first suction pipe section 71 of the suction pipe 7.

[0043] After the electrode head 12 in the electrode assembly cuts the wound, under the action of the air pressure of the pneumoperitoneum machine 1, the cleaning liquid in the liquid storage bag 4 cleans the wound through the second flushing pipe section 62 of the flushing tube 6 and the metal tube 11, and the waste liquid generated by the cleaning flows into the waste liquid bag 5 through the metal tube 11 and the first suction pipe section 71 of the suction tube 7 for collection.

[0044] In this embodiment, the electrode assembly also includes an electrode upper cover 13, an electrode lower cover 14 and a knob 15. The electrode upper cover 13 and the electrode lower cover 14 are connected to form a chamber. The third connecting valve 10 is arranged in the chamber. The flushing tube 6 and the suction tube 7 are partially located in the chamber. The knob 15 is rotatably arranged on the electrode lower cover 14 and is located between the flushing tube 6 and the suction tube 7; the knob 15 can squeeze the flushing tube 6 and the suction tube 7. During the rotation of the knob 15, the knob 15 can put the flushing tube 6 and / or the suction tube 7 in a closed state.

[0045] It should be noted that, in the initial state, the distance between the knob 15 and the inner walls on both sides of the electrode lower cover 14 is equal, and the distance is equal to twice the wall thickness of the flushing tube 6 or the suction tube 7. At this time, the second flushing tube segment 62 of the flushing tube 6 and the first suction tube segment 71 of the suction tube 7 are squeezed at the same time, so that the second flushing tube segment 62 and the first suction tube segment 71 are both in a closed state; and when the knob 15 is rotated, the distance between the knob 15 and the inner wall on one side of the electrode lower cover 14 remains unchanged, and the distance between the knob 15 and the inner wall on the other side of the electrode lower cover 14 increases. In this process, one of the second flushing tube segment 62 and the first suction tube segment 71 can be in an open state, and the other can be in a closed state.

[0046] When the wound needs to be cleaned, the knob 15 is rotated to open the flushing tube 6 and close the suction tube 7. At this time, the cleaning liquid in the liquid storage bag 4 cleans the wound through the second flushing tube section 62 of the flushing tube 6 and the metal tube 11; when the wound is cleaned, the knob 15 is rotated in the opposite direction to open the suction tube 7 and close the flushing tube 6. At this time, the waste liquid generated by cleaning flows into the waste liquid bag 5 through the metal tube 11 and the first suction tube section 71 of the suction tube 7 for collection.

[0047] In this embodiment, the knob 15 includes a rotating part 151 and a squeezing part 152 connected to each other. A rotating shaft is provided on the electrode lower cover 14. The squeezing part 152 is rotatably connected to the rotating shaft. A through hole 131 is provided on the electrode upper cover 13 for the rotating part 151 to extend out. The squeezing part 152 can squeeze the flushing tube 6 and the suction tube 7. During the rotation of the squeezing part 152 around the rotating shaft, the squeezing part 152 can keep the flushing tube 6 and / or the suction tube 7 in a closed state.

[0048] The rotating part 151 is columnar and extends out of the through hole 131 on the electrode upper cover 13 for easy operation; the extruding part 152 has a fan-shaped cross section and is provided with a mounting hole, through which the extruding part 152 is rotatably connected to the rotating shaft.

[0049] When the wound needs to be cleaned, the rotating part 151 is rotated to one side, and the squeezing part 152 makes the flushing tube 6 in an open state and the suction tube 7 in a closed state. At this time, the cleaning liquid in the liquid storage bag 4 cleans the wound through the second flushing tube section 62 of the flushing tube 6 and the metal tube 11; when the wound is cleaned, the rotating part 151 is rotated to the other side, so that the suction tube 7 is in an open state and the flushing tube 6 is in a closed state. At this time, the waste liquid generated by cleaning flows into the waste liquid bag 5 through the metal tube 11 and the first suction tube section 71 of the suction tube 7 for collection.

[0050] In this embodiment, the electrode assembly further includes a spring sheet 16 , a first slot 1521 is formed on the extrusion portion 152 , a second slot 141 is formed on the electrode lower cover 14 , and two ends of the spring sheet 16 are respectively engaged with the first slot 1521 and the second slot 141 .

[0051] The spring sheet 16 can produce deformation. When the rotating part 151 rotates, the extrusion part 152 rotates synchronously, and the spring sheet 16 produces deformation. When the rotating part 151 is released, the extrusion part 152 is driven to reset under the elastic force of the spring sheet 16, so that the rotating part 151 and the extrusion part 152 return to their initial state. At this time, the flushing tube 6 and the suction tube 7 are both in a closed state.

[0052] It is understandable that the spring sheet 16 may also be replaced by other elastic members as long as they can help the knob 15 to reset.

[0053] In this embodiment, the pneumoperitoneum machine pipeline system also includes an electrode main unit (not shown in the figure), and a spring column 142 is provided on the electrode lower cover 14, and an electrical connecting piece 143 and a spring 144 are sleeved on the spring column 142. One end of the spring 144 abuts against the electrical connecting piece 143, and the other end of the spring 144 abuts against the metal tube 11. The electrical connecting piece 143 is connected to the electrode main unit through a power cord.

[0054] The electrical connecting piece 143 is a copper sheet, and the spring 144 is also conductive. The length direction of the spring column 142 is perpendicular to the length direction of the metal tube 11. The electrical connecting piece 143 and the spring 144 are both sleeved on the spring column 142. Under the elastic force of the spring 144, the two ends of the spring 144 can stably abut against the electrical connecting piece 143 and the metal tube 11 to ensure the stability of the output of the electrode head 12.

[0055] In this embodiment, a portion of the metal tube 11 extends out of the cavity, and a portion of the metal tube 11 outside the cavity is sheathed with an insulating tube.

[0056] It should be noted that the portion of the metal tube 11 outside the cavity may come into contact with the human body. Therefore, by sheathing an insulating tube on the portion of the metal tube 11 outside the cavity, an insulating effect can be achieved to prevent damage caused by contact with the human body.

[0057] In this embodiment, a plurality of guide holes are formed on one of the electrode upper cover 13 and the electrode lower cover 14 , and a plurality of fixing posts 145 are disposed on the other one. The plurality of fixing posts 145 are matched with the plurality of guide holes in a one-to-one correspondence.

[0058] Each fixing post 145 is plug-fitted with the corresponding guide hole, and each fixing post 145 is interference fit with the corresponding guide hole. When multiple fixing posts 145 are matched with multiple guide holes one by one, the electrode upper cover 13 and the electrode lower cover 14 can be stably connected as one.

[0059] Exemplarily, a plurality of guide holes are opened on the electrode upper cover 13 , and a plurality of fixing posts 145 are provided on the electrode lower cover 14 , and the plurality of fixing posts 145 are matched with the plurality of guide holes in a one-to-one correspondence.

[0060] In other embodiments, the electrode upper cover 13 and the electrode lower cover 14 may also be connected by other means, for example, the electrode upper cover 13 and the electrode lower cover 14 are connected by bolts, or the electrode upper cover 13 and the electrode lower cover 14 are connected by snaps.

[0061] In this embodiment, the second pipeline group includes a second air intake pipe 17 and a second exhaust pipe 18, one end of the second air intake pipe 17 is connected to the first connecting valve 8, the other end of the second air intake pipe 17 is connected to the smoke exhaust piercer 3, one end of the second exhaust pipe 18 is connected to the second connecting valve 9, and the other end of the second exhaust pipe 18 is connected to the smoke exhaust piercer 3.

[0062] The second intake pipe 17 is in communication with the third end of the first communication valve 8 , and the second exhaust pipe 18 is in communication with the third end of the second communication valve 9 .

[0063] The pneumoperitoneum machine 1 delivers carbon dioxide into the abdominal cavity through the first air inlet pipe 21 of the filter 2, the second air inlet pipe 17 and the smoke exhaust puncture device 3 in sequence to establish pneumoperitoneum and maintain a constant pressure state. The smoke generated when using the electrode head 12 can also be discharged from the body through the smoke exhaust puncture device 3, the second exhaust pipe 18, the first exhaust pipe 22 of the filter 2, and the pneumoperitoneum machine 1 in sequence to ensure a clear surgical field of view.

[0064] Optionally, the flushing tube 6, the suction tube 7, the second air inlet pipe 17 and the second exhaust pipe 18 are all PVC tubes.

[0065] The working principle of a pneumoperitoneum machine pipeline system provided in an embodiment of the present application is as follows: during the working process of the pneumoperitoneum machine pipeline system, the electrode main unit is started, and the electrode head 12 is driven to cut a wound. Under the action of the air pressure of the pneumoperitoneum machine 1, the cleaning liquid in the liquid storage bag 4 cleans the wound through the flushing tube 6 and the metal tube 11, and the waste liquid generated by the cleaning flows into the waste liquid bag 5 through the metal tube 11 and the suction tube 7 for collection; at the same time, the pneumoperitoneum machine 1 delivers carbon dioxide into the abdominal cavity through the first air inlet pipe 21, the second air inlet pipe 17 and the smoke exhaust puncture device 3 in sequence to establish pneumoperitoneum and maintain a constant pressure state. The smoke generated by the electrode head 12 can also be discharged from the body through the smoke exhaust puncture device 3, the second exhaust pipe 18, the first exhaust pipe 22, and the pneumoperitoneum machine 1 in sequence, ensuring a clear surgical field of view. The entire pneumoperitoneum machine pipeline system does not require a negative pressure suction device, which reduces the waste of surgical instrument resources and reduces the risk of misoperation.

[0066] The technical effects of a pneumoperitoneum machine pipeline system provided in an embodiment of the present application include at least: under the action of the pneumoperitoneum machine 1, the cleaning fluid in the liquid storage bag 4 can clean the wound, and the waste liquid generated by the cleaning can flow into the waste liquid bag 5 for collection; the pneumoperitoneum machine 1 can deliver carbon dioxide into the abdominal cavity to establish pneumoperitoneum and maintain a constant pressure state; the smoke generated by the electrode head 12 can be discharged from the body in time to ensure a clear surgical field of view; the setting of the knob 15 can control the flushing tube 6 and the suction tube 7 to be in an open state or a closed state, so that the wound cleaning process is controllable, and the knob 15 can be restored to its initial state under the elastic force of the spring sheet 16.

[0067] To sum up, the embodiment of the present application provides a pneumoperitoneum machine pipeline system. During the working process of the pneumoperitoneum machine pipeline system, the pneumoperitoneum machine pipeline system can clean the wound, collect the waste liquid generated by cleaning, establish pneumoperitoneum and maintain a constant pressure state, and the smoke generated in the abdominal cavity can be discharged from the body through the pneumoperitoneum machine pipeline system in time to ensure a clear surgical field of view. The entire pneumoperitoneum machine pipeline system does not require a negative pressure suction device, which reduces the waste of surgical instrument resources and reduces the risk of misoperation.
