The invention relates to a two-channel suction syringe used for a minimally invasive surgery, which comprises an extension pipeline (10), a main pipeline body (20), a suction mechanism (30) and a transfusion mechanism (40), wherein the rear end of the extension pipeline (10) is communicated with the front end of the main pipeline body (20) the suction mechanism (30) and the transfusion mechanism (40) are communicated with the main pipeline body (20) and particularly, the extension pipeline (10) of the suction syringe comprises a transfusion channel (101) and a suction channel (102) which are isolated from each other. The technical scheme has the beneficial effects that due to the structural design of the two channels, the transfusion channel (101) is isolated from the suction channel (102) in the aspect of physics, the washing liquid is not polluted, the two-channel suction syringe has the functions of sintering and sucking smoke, the surgery time is reduced, and the surgery efficiency is improved.用於微創手術的雙通道抽吸沖洗器,包括延伸管道(10)、管道主體(20)、抽吸機構(30)和輸液機構(40);該延伸管道(10)後端與管道主體(20)前端連通,該抽吸機構(30)與輸液機構(40)均與管道主體(20)連通,尤其是,該抽吸沖洗器的延伸管道(10)包括兩個相互隔離的輸液管道(101)和抽吸管道(102)。該技術手段的功效在於:採用雙通道結構性設計,把輸液管道(101)和抽吸管道(102)在物理上相互隔離,使沖洗液不被污染,並具有燒結與吸取煙塵功能,能減少手術時間,提高手術效率。10...延伸管道101...輸液管道102...抽吸管道103...電燒探頭伸縮管道1031...燒結探頭20...管道主體21...廢液出口22...輸液進口30...抽吸機構31...抽吸管道室32...活動抽吸管道321...開口33...抽吸按柄34...復位彈性部件36...廢液管道40...輸液機構41...輸液管道室42...輸液活動管道43...輸液按柄44...復位彈性部件46...輸液管道50...煙塵過濾機構51...煙塵通道A...密封圈B...密封圈C...密封圈D...密封墊圈E...密封墊圈
