Even if the tip of the drainage puncture needle 602 comes into contact with the patient's abdominal tissue during the drainage process, the effusion in the abdominal cavity can still enter the drainage hose 601 and the drainage puncture needle 602 through the circle of liquid inlet holes A6021.

[0081] In addition, because the cross connecting frame 604 is fixedly mounted on the movable sealing tube 603, and one end of the steel wire rope 605 is fixedly mounted on the movable sealing disk 301, and the other end of the steel wire rope 605 is fixedly mounted on the cross connecting frame 604, when the movable sealing disk 301 moves downward, a circle of liquid inlet holes B6031 and a circle of liquid inlet holes A6021 can be automatically misaligned, so that the movable sealing tube 603 automatically seals a circle of liquid inlet holes A6021, ensuring that when a small amount of fluid in the abdominal cavity is extracted, the extraction force is only generated by the head end of the drainage puncture needle 602, which is beneficial to improve the extraction effect of fluid in the abdominal cavity and avoid a large amount of fluid remaining in the abdominal cavity.

[0082] In the embodiment of the present disclosure, Figure 12 As shown, the auxiliary storage unit 700 includes: a rectangular connecting sleeve 701, an auxiliary storage shell 702 and a movable sealing cap 703; the rectangular connecting sleeve 701 is fixedly mounted on the outer wall of the effluent storage tank 200; the auxiliary storage shell 702 is slidably mounted on the rectangular connecting sleeve 701, and the rectangular connecting sleeve 701 and the auxiliary storage shell 702 are further connected by screws; the movable sealing cap 703 is slidably mounted on the auxiliary storage shell 702, and the auxiliary storage shell 702 and the movable sealing cap 703 are further connected by screws; the auxiliary storage unit 700 also includes: a rubber sealing ring B704 and a rubber sealing ring C705; the rubber sealing ring B704 is mounted on the auxiliary storage shell 702, and the rubber sealing ring B704 is also in contact with the rectangular connecting sleeve 701; the rubber sealing ring C705 is mounted on the movable sealing cap 703, and the rubber sealing ring C705 is also in contact with the auxiliary storage shell 702;

[0083] Its specific function is: because the auxiliary storage shell 702 is slidably installed on the rectangular connecting sleeve 701, and the rectangular connecting sleeve 701 and the auxiliary storage shell 702 are also connected by screws, it is convenient for the staff to add an appropriate number of auxiliary storage shells 702 according to the patient's abdominal effusion situation to ensure that the effusion in the patient's abdominal cavity can be completely discharged; and because the movable sealing cap 703 is slidably installed on the auxiliary storage shell 702, and the auxiliary storage shell 702 and the movable sealing cap 703 are also connected by screws, it has a sealing effect on the outermost auxiliary storage shell 702; at the same time, when the patient's abdominal cavity has less effusion, the staff can directly connect the movable sealing cap 703 to the rectangular connecting sleeve 701, which is more versatile and suitable for use by different patients.

[0084] The specific usage and function of this embodiment are as follows:

[0085] When the present invention is used, the puncture sheath 901 is first punctured into the peritoneal cavity (the assistant uses forceps to fix the position of the puncture sheath 901), and then the ventricular catheter end of the cerebrospinal fluid peritoneal shunt tube 800 is implanted into the ventricle, and the peritoneal catheter end of the cerebrospinal fluid peritoneal shunt tube 800 is extended through the puncture sheath 901 into the peritoneal cavity. The hydrocephalus is diverted into the peritoneal cavity through the cerebrospinal fluid peritoneal shunt tube 800. When the peritoneal catheter end of the cerebrospinal fluid peritoneal shunt tube 800 passes through the puncture sheath 901, the endoscope 905 located in the endoscope channel 904 observes the extension depth of the cerebrospinal fluid peritoneal shunt tube 800. When it is necessary to remove the puncture sheath 901 from the periphery of the cerebrospinal fluid peritoneal shunt tube 800, When coming in, use two fingers to pry open the pull ring 9032b, and the pull ring 9032b drives the elastic sheet 9032 to deviate to the side away from the push-pull plate 9031, so that the protrusion 9032a and the groove 9031a are separated, and the push-pull plate 9031 is pushed outward, and the push-pull plate 9031 drives the strip plug plate 902 to separate from the strip card slot 9011, (the endoscope 905 is separated from the puncture sheath 901 together with the strip plug plate 902), then the puncture sheath 901 is pulled out of the abdominal cavity, and the puncture sheath 901 is moved to align the cerebrospinal fluid-peritoneal shunt tube 800 with the strip card slot 9011, and then the puncture sheath 901 and the cerebrospinal fluid-peritoneal shunt tube 800 are separated through the strip card slot 9011.

[0086] When extracting peritoneal effusion, the staff connects the connecting bracket 100 to the bed or operating table, punctures the puncture sheath 901 into the peritoneal cavity, and then assists the insertion of the drainage puncture needle 602 through the endoscope 905 in the endoscope channel 904 to ensure that the drainage puncture needle 602 is accurately inserted into the appropriate position in the patient's abdominal cavity. The setting of a circle of elastic positioning rods 402 plays a positioning role for the movable sealing disk 301; then the staff adds an appropriate number of auxiliary storage shells 702 according to the patient's peritoneal effusion situation to ensure that the effusion in the patient's abdominal cavity can be completely discharged. The setting of the auxiliary storage shell 702 plays a sealing role for the outermost auxiliary storage shell 702; at the same time, when the patient's peritoneal effusion is less, the staff can The movable sealing cap 703 is directly connected to the rectangular connecting sleeve 701, which is more versatile and suitable for use on different patients. When the effusion in the abdominal cavity is drained into the effusion storage tank 200 through the drainage hose 601 and the drainage puncture needle 602, the air in the effusion storage tank 200 can be discharged through a circle of exhaust holes A5011 and a circle of exhaust holes B5012. The setting of the support spring B505 supports the movable sealing cap 502, ensuring that when the abdominal effusion is drained, the air in the effusion storage tank 200 can be discharged smoothly through a circle of exhaust holes A5011 and a circle of exhaust holes B5012. When the effusion in the patient's abdominal cavity is less than that which is not conducive to discharge, the staff can press the movable sealing cap 502 downwards. At this time, the movable sealing cap 502 is pressed down. The sealing cover 502 first seals a circle of exhaust holes B5012, and then the circular push rod 503 pushes the movable sealing disk 301 downward to automatically separate a circle of elastic positioning rods 402 from the annular groove 201. At this time, under the action of the weight of the accumulated fluid in the effusion storage tank 200 plus the weight of the movable sealing part 300 and the elastic positioning part 400, the movable sealing disk 301 can automatically move downward, so that the drainage puncture needle 602 automatically generates an extraction force, which is conducive to the rapid discharge of a small amount of effusion in the abdominal cavity. When extracting a small amount of abdominal effusion, the staff can manually adjust the position of the head end of the drainage puncture needle 602 to ensure that the head end of the drainage puncture needle 602 will not be blocked; when the movable sealing cover 502 contacts the effusion storage tank 200, strong force is applied. The magnetic ring 506 attracts the effusion storage tank 200 and limits the movable sealing cover 502. The interference fit connection between the movable sealing tube 603 and the drainage puncture needle 602 prevents the movable sealing tube 603 from changing position when the drainage puncture needle 602 is inserted into the patient's abdominal cavity. When the effusion in the abdominal cavity is drained into the effusion storage tank 200 through the drainage hose 601 and the drainage puncture needle 602, the effusion in the abdominal cavity can enter through the head end of the drainage puncture needle 602 and a circle of liquid inlet holes A6021. Even if the head end of the drainage puncture needle 602 contacts the patient's abdominal cavity tissue during the drainage process, the effusion in the abdominal cavity can still enter the drainage hose 601 and the drainage puncture needle 602 through the circle of liquid inlet holes A6021.When the movable sealing disk 301 moves downward, the circle of liquid inlet holes B6031 and the circle of liquid inlet holes A6021 automatically shift, allowing the movable sealing tube 603 to automatically seal the circle of liquid inlet holes A6021. This ensures that when extracting a small amount of fluid from the abdominal cavity, the extraction force is generated only by the tip of the drainage puncture needle 602, which is beneficial for improving the extraction effect of the fluid in the abdominal cavity and preventing a large amount of fluid from remaining in the abdominal cavity.
