[0005] The above technical problem of the present invention is solved by the following technical solutions: A minimally invasive surgical system for hepatic hydatid disease, comprising a suction cup assembly, wherein the suction cup assembly is provided with an inner tube, and one end of the inner tube is provided with a sealing connection structure; a component to be used is inserted into the inner tube of the suction cup assembly, and the component to be used is sealed and connected to the suction cup assembly through a sealing connection structure; the component to be used is one of a puncture assembly and a treatment assembly; the suction cup assembly is used in sequence with each component to be used. The inner tube of the suction cup assembly is used to connect various components, such as a puncture assembly or a treatment assembly. The outer tube is connected to the suction cup, and the suction cup is always attached to the patient. According to different surgical requirements, the connection assembly is first inserted into the inner tube for puncture, and the puncture assembly is removed after puncture; then different use components are selected according to the size of the parasite block. A suction cup assembly can be equipped with different operating components, so that parasites in various situations can be removed. For the patient, the surgical incision is small, and only the suction cup component is in constant contact, which can reduce the pain caused by changing instruments. At the same time, it saves operation time, causes less damage to the patient, and has a good surgical effect.

[0006] Preferably, the processing component is an endoscope flushing component or a crushing and suction component. The endoscope component can flush the wound and suction small cyst masses.

[0018] The technical solution of the invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] Example:

[0020] like Figure 1 and 2As shown in 3 and 4, a minimally invasive medical surgery system for hydatid cysts includes a suction cup component A, a puncture component B, an endoscope flushing component and a crushing and suction component.

[0021] The suction cup assembly A includes an inner tube 7 and an outer tube 6 whose central axes coincide with each other. One end of the inner tube 7 is connected to an inner adapter seat 2. A rubber cap 1 is installed above the inner adapter seat 2. A through hole is provided in the center of the rubber cap 1. The diameter of the through hole is smaller than the diameter of the inner tube 7. A suction cup body 5 is connected to one end of the outer tube 6. A suction cup valve 3 of the suction cup assembly is connected to the suction cup body 8. An arc-shaped bowl-shaped suction cup 8 is fixed to the other end of the outer tube 6. The suction cup valve 3 of the suction cup assembly is externally connected to negative pressure to adsorb the suction cup 8 to the patient's surgical site. A sealing ring 4 is provided between the inner adapter seat 2 and the suction cup body 5.

[0022] The puncture assembly B includes a puncture head 20, which is connected to a puncture tube 17, and a puncture sheath 19 is connected to the outer surface of the puncture tube 17. The outer part of the puncture sheath 19 is connected to a Y-shaped pipe 35 through a puncture sheath body 18, and one part of the Y-shaped pipe coincides with the axis of the puncture sheath 19, and the other part of the Y-shaped pipe 35 is a negative pressure hose interface 16. The end of the puncture sheath 17 is connected to the puncture handle 12 through a locking joint 14 and a locking seat 15, and the locking joint 14 and the puncture tube 17 are sealed by a sealing ring 4. The other end of the puncture tube 17 is connected to a puncture valve 11, and the puncture valve 11 is installed on the puncture handle 12.

[0023] The endoscope flushing assembly includes an endoscope sheath 29, an endoscope outer tube 26 is installed in the endoscope sheath 29, and a Y-shaped pipe 35 is connected to the outside of the endoscope sheath 29 through an endoscope sheath body 28, one part of the Y-shaped pipe coincides with the axis of the endoscope sheath 29, and the other part of the Y-shaped pipe 35 is a negative pressure hose interface 16. The end of the endoscope sheath 29 is connected to the endoscope holder 24 through a locking joint and a locking seat, and the locking joint and the endoscope outer tube are sealed by a sealing ring. An endoscope valve 25 is installed on the endoscope holder, and the end of the endoscope holder 25 is connected to the endoscope 21.

[0024] The pulverizing and suction assembly includes a pulverizing sheath 39, in which an inner planer 37 is installed, and a planer outer tube 35 is connected to the inner planer 37. One end of the inner planer 37 is connected to a medical planer 31. A pulverizing and suction port 32 is provided at one end of the pulverizing sheath 39, and the other end of the pulverizing sheath 39 is connected to a Y-shaped pipe 35 through a pulverizing sheath body 38, and the Y-shaped pipe includes a negative pressure hose interface 16. The end of the pulverizing sheath 39 is connected to the medical planer 31 through a locking joint 14 and a locking seat 15. The locking joint 14 and the planer outer tube 35 are sealed by a sealing ring 4.

[0025] like Figure 5As shown, when in use, after the suction cup assembly A sucks the outer membrane of the parasite cyst, the puncture sheath 19 is inserted into the central through hole of the rubber cap 1, and the elasticity of the rubber cap 1 is used to seal the puncture sheath 19. The puncture head 20 in the puncture sheath 19 extends out of the inner tube 7, and the puncture head 20 is inserted into the outer membrane of the parasite cavity. After reaching the cyst cavity, the excessive cyst cavity pressure causes parasites to leak out. The leaked material is sucked out through the negative pressure cavity of the suction disc assembly and then sucked out through the suction cup valve 3.

[0026] The first step of parasite aspiration after puncture is to aspirate the parasites through the puncture suction port at the end of the puncture head through the puncture tube 17 and then through the puncture valve 11.

[0027] The second step of parasite suction after puncture is to pull the puncture tube 17 out of the puncture sheath 19. When the puncture head 20 reaches the locking joint 14, the negative pressure hose interface 16 is connected with the puncture sheath 19 to suck out the parasites in the cyst cavity.

[0028] When blockage occurs or the situation in the cavity is to be observed, the puncture sheath 19 is taken out of the inner tube 7, the endoscope sheath 29 is inserted into the inner tube 7, and the endoscope assembly is installed into the inner tube 7 of the suction cup assembly, and the endoscope sheath 29 is elastically sealed by the rubber cap 1. The endoscope lens is kept clear by flushing water through the endoscope valve 25, and water and parasites are sucked out through the gap between the endoscope sheath 29 and the endoscope outer tube 26.

[0029] When a large cyst appears and cannot be sucked out by the endoscope assembly and the puncture assembly, the endoscope assembly is removed from the inner tube, and the crushing and suction assembly is inserted into the inner tube. The crushing sheath 39 is inserted into the central through hole of the rubber cap 1, and the crushing sheath 39 is sealed by the elasticity of the rubber cap 1. The inner planer 37 of the medical planer rotates, and there is a gap between the crushing sheath 39 and the inner planer 37. The large cystic mass is sucked to the blade head of the inner planer 37 through the negative pressure hose interface 16, and the inner blade head is rotated to crush the large cystic mass, and then sucked out.

[0030] By selecting different components to be used in the inner tube, various hydatid cysts can be eliminated and the parasites can be sucked out. The operation is convenient and takes a short time.
