Description

Arthroscope waste liquid suction device with rapid self-cleaning function Technical Field The invention relates to the technical field of medical instruments, in particular to an arthroscope waste liquid suction device with a rapid self-cleaning function. Background During arthroscopic surgery, it is often necessary to use a waste suction device to clean the surgical field of irrigation fluid, blood, and cut tissue debris or gout stones. The traditional waste liquid suction device adopts a direct negative pressure suction mode to collect the waste liquid into the liquid storage tank. When waste solutions containing large bone fragments or hard stones are treated, these large particulate materials can become stuck in the aspiration syringe or connecting tubing, causing tubing blockage, leading to reduced aspiration efficiency and even interruption of the surgical procedure. In order to alleviate the clogging problem, some existing suction devices provide a filter element at the collection end. However, as suction progresses, large particle debris in the waste liquid rapidly builds up on the surface of the filter element, blocking the filter pores, and causing negative pressure to be unable to be transmitted normally. This not only needs the frequent shut down of medical personnel to clear up filter element, and the solid-state piece that is blocked often mixes together with the waste liquid moreover, is inconvenient for taking out the piece alone after the operation and carries out pathological assay analysis. In addition, after the operation is completed, a large amount of blood, fat and tissue debris is attached to the elongated tube and the inside of the cylinder of the waste liquid suction device. The existing device generally does not have an in-situ cleaning function, and medical staff is required to manually brush and rinse the pipelines after detaching the pipelines one by one. The cleaning mode is time-consuming and labor-consuming, dead corners inside the pipeline are difficult to clean thoroughly, dirt can remain and bacteria can be bred, and the risk of cross infection in subsequent use is increased. Disclosure of Invention Aiming at the defects of the prior art, the invention provides an arthroscope waste liquid suction device with a rapid self-cleaning function, which solves the problems that the pipeline and a filter screen are blocked due to the fact that the existing waste liquid suction device sucks large particle fragments, and the pipeline is difficult to clean in situ after operation and is easy to cause cross infection due to residual dirt.
