Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a grip-type suction device. Background Art

[0002] During urological surgery, for diseases such as bladder stones, kidney stones, and urethral strictures, there are often residual liquid or foreign matter or congestion during the operation, which needs to be flushed and suctioned to ensure the smooth progress of the operation. A suction device is commonly used in the operation. The suction device uses a vacuum generator to create a negative pressure state in the collection bottle. In this way, the flushing fluid can be drawn into the collection bottle through the extraction tube through the air pressure difference to complete the suction extraction work;

During the flushing work, some flushing liquids are too large in capacity. When the collecting bottle is full, the extraction can only be suspended. The collecting bottle needs to be disassembled, emptied, and reinstalled before the extraction work can continue. This operation method is more troublesome and less convenient to use.
