[0002] In the percutaneous nephrolithotomy, ureteroscopy surgery process, usually need to net cavity perfusion, in order to form high pressure and certain volume perfusion fluid in the local space of cavity in short time, reach the effect of clear vision, then timely withdraw from the endoscope again;
[0003] When withdrawing from the endoscope, the higher pressure saline in the channel will flow back to the injection tube along the pressure relief channel relatively quickly, and at the same time, the substances in the cavity will also flow back to the injection tube along the liquid, which cannot realize clear vision and reduces the working effect. UTILITARY MODEL
[0004] The utility model discloses a waterproof cap of endoscope, aims at solving the technical problem that when withdrawing from the endoscope, the higher pressure saline in the channel will flow back to the injection tube along the pressure relief channel relatively quickly, and at the same time, the substances in the cavity will also flow back to the injection tube along the liquid, which cannot realize clear vision and reduces the working effect.
[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:
[0006] A waterproof cap of endoscope, including the pipe fitting, the left side fixedly connected with the cap of the pipe fitting, the inside fixedly connected with the probe of cap, the left side fixedly connected with the transparent glass of cap, the inside right side fixedly connected with the limit rod of cap, the rod wall slidingly connected with the plug of limit rod, the right side fixedly connected with the spring of limit rod, the right side fixedly connected with the inside left side of plug, the inside right side of plug is evenly opened L shape and is drained, the right side evenly opened with the round hole of cap.
[0007] Preferably, the left side diameter of the plug is greater than the right side diameter, and the left side of the plug is evenly provided with a rectangular groove.
[0008] Preferably, the inner wall of the pipe fitting is fixedly connected with a circular ring, and the left side of the circular ring is evenly provided with a plug rod.
[0009] Preferably, the inside of the cap is fixedly connected with a lamp holder.
[0010] As can be seen from the above, the waterproof cap of endoscope has the advantages that when the saline enters the human body, the plug is moved by the pressure, the injection of saline is realized, when the liquid injection is stopped, the plug is reset by the spring, thereby avoiding the backflow of saline, playing a certain waterproof role and improving the use effect.
