[0027] like Figure 1 and Figure 2 As shown, an anti-leakage device provided by an embodiment of the present invention comprises a telescopic member 1, a sponge 2, a medical patch 3 and a drainage tube 4, wherein: the sponge 2 comprises a mounting surface 21 and an operation area surface 22 arranged in a back-to-back manner, and a side surface 23 connected to the mounting surface 21 and the operation area surface 22, the mounting surface 21 is provided with a mounting hole, and the operation area surface 22 is used to fit and be installed in the operation area; the telescopic member 1 comprises an elastic adjustment portion 11, a fixing portion 12 and an elastic telescopic portion 13 which are connected in sequence and can be adjusted to any angle, and is provided with a through hole 15 penetrating the adjustment portion 11, the fixing portion 12 and the telescopic portion 13, and the through hole 15 is used to For installing the working channel 6; the fixed part 12 includes an overlapping surface 18 and a fitting surface arranged in back to back, and the fitting surface is fixedly installed on the mounting surface 21; the telescopic part 13 can be telescoped in a direction perpendicular to the mounting surface 21, and is installed in the mounting hole; the medical film 3 includes an overlapping part and a fitting part that are sealed and connected to each other, the overlapping part is sealed and overlapped on the overlapping surface 18, and the fitting part is sealed and fitted on the side surface 23 and the mounting surface 21; the first end 51 of the drainage tube 4 is inserted into the sponge 2 through the side surface 23, and is sealed and connected to the side surface 23, and the second end 52 of the drainage tube 4 is located outside the sponge 2, and is used to be connected to the negative pressure tube.

[0028] It should be noted that: a negative pressure tube is installed in the hospital operating room, which provides negative pressure for the anti-leakage device through the drainage tube 4; the telescopic part 13 is located in the sponge 2; when the adjustment part 11 is telescoped at any angle, the fixed part 12 installed on the sponge 2 will still not telescope with the telescoped adjustment part 11, but will only move with the sponge 2 as the sponge 2 expands or contracts, and will not move alone; the medical film 3 is a biopermeable film, which is an adhesive polyurethane film with micropores of 0.25-1.0gm in diameter, which can pass water vapor but not liquid water. This medical film 3 can be sealed and installed on the surface of other objects after being attached to them; surgical instruments are installed in the working channel 6 for surgical operations.

[0029] The anti-leakage device provided by the present invention includes a telescopic part 1, a sponge 2, a medical film 3 and a drainage tube 4. The surgical area surface 22 on the anti-leakage device is fitted and installed in the surgical area. The surgical instrument is installed in the working channel 6. The adjustment part 11 can be extended and retracted at any angle as the surgical instrument is operated. The sponge 2, the surgical area, the medical film 3 and the fixing part 12 define a closed space. The sponge 2 expands and increases after absorbing flushing water. The drainage tube 4 draws the flushing water in the sponge 2 out of the sponge 2, and the sponge 2 contracts. The telescopic part 13 installed in the sponge 2 expands and retracts as the sponge 2 changes. The sponge 2 continuously absorbs flushing water, and the drainage tube 4 also continuously draws the flushing water in the sponge 2 out, thereby preventing the flushing water from entering the surgical area, ensuring the dryness of the surgical area, and reducing the probability of wound infection in patients.

[0030] like Figure 1 As shown, the portion of the through hole 15 located at the telescopic portion 13 is a trumpet through hole 17, and the trumpet mouth 16 of the trumpet through hole 17 is away from the fixing portion 12.
