Embodiment 1
[0048] Such as Figure 1 to Figure 5 The shown auxiliary smoke exhaust and drainage device for single-port laparoscopic surgery includes a syringe 1, a puncture needle 4 and an inner tube 12, the puncture needle 4 is used to puncture the abdominal wall 19, and the inner tube 12 is provided with several Through hole 13, the outer tube 3 is communicated with the syringe 1, the inside of the syringe 1 and the inner tube 3 form a passage for the puncture needle 4 or the inner tube 12 to pass through, and the outer wall of the outer tube 3 An air intake part 6, an outer clamping part and a second air bag 9 are arranged on the top, the air intake part 6 communicates with the second air bag 9, and the second air bag 9 is used to expand when the air intake part 6 is inflated , and abut against the inner side of the abdominal wall 19 , the outer clamping member is used to abut against the outer side of the abdominal wall 19 , and cooperate with the inflated second air bag 9 to clamp th...
Embodiment 2
[0059] On the basis of Example 1, such as Figure 1 to Figure 5 As shown, the outer clamping part is a first air bag 8, and the first air bag 8 communicates with the air intake part 6, and the first air bag 8 is used for expanding when the air intake part 6 is inflated, and with the expanded The second balloons 9 jointly clamp the abdominal wall 19 .
[0060] In this embodiment, when no gas is injected, the first airbag is shrunk and attached to the outer tube, and when the external air enters the first airbag through the air supply unit, the intake pipe, and the intake piece, the first airbag expands , and the lower surface of the first airbag abuts against the outer side of the abdominal wall, so as to clamp the abdominal wall together with the inflated second airbag.
[0061] In some embodiments, the first air channel between the first air bag and the air intake piece, and the second air channel between the second air bag and the air intake piece can be divided into two by...
Embodiment 3
[0064] On the basis of Example 1, such as Figure 9 and Figure 10 As shown, the outer clamping member includes a housing 21 detachably connected to the outer tube 3, a push plate 23 is slidably disposed inside the housing 21, and a third air bag 22 is disposed above the push plate 23, The third airbag 22 is in communication with the air intake member 6, a connecting rod 25 is connected under the push plate 23, and the connecting rod 25 moves through the bottom of the housing 21 and is connected with a pressing plate 27, the pressing plate 27 For abutting against the outside of the abdominal wall 19 .
[0065] In some embodiments, the first air channel between the third air bag and the air intake piece, and the second air channel between the second air bag and the air intake piece can be divided into two by one air channel, or Two airways are set separately. In one or more embodiments, the air passage can be either a trachea located in the outer tube, or an air channel prov...
