Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an anti-backflow double-channel suction flusher for a endoscope.
Background
Laparoscopic surgery is a newly developed minimally invasive method, and is a necessary trend of future surgical method development; is an operation performed by using a laparoscope and related instruments. During operation, a cold light source is used for providing illumination, a laparoscope lens is inserted into the abdominal cavity, an image shot by the laparoscope lens is transmitted to a post-stage signal processing system through an optical fiber by using a digital shooting technology and is displayed on a special monitor in real time, then a doctor analyzes and judges the condition of a patient through images of different angles of organs of the patient displayed on a monitor screen, and the operation is performed by using a special laparoscope instrument.
When laparoscopic surgery is performed, blood, effusion, exudates, contents in thoracic organs and the like flowing out of tissues of an affected part of a patient cannot be cleaned in time, so that operation and operation vision of a doctor are affected, observation of the affected part by the doctor is inconvenient, and meanwhile, infection of the affected part is easily caused, so that normal performance of laparoscopic surgery is affected. Therefore, in laparoscopic surgery, an aspirator flusher is often used to aspirate and remove the contents of hemorrhage, exudates, pus and thoracic organs in laparoscopic surgery, so that the visual field is clear and the pollution chance is reduced.
Referring to fig. 1, the aspirator used in the related art is composed of two parts, a left side aspiration tube part a is a hollow tube, and is connected with a middle three-way valve b through a spiral structure, the three-way valve is connected with two pipelines c, one pipeline c is connected with a water inlet tube, and the other pipeline c is connected with a negative pressure aspiration bottle. When in imbibition, substances such as blood, effusion, exudation, contents in thoracic viscera and the like flowing out of the tissue of the affected part can be inhaled through the hollow tube a under the action of the three-way valve b; during flushing, flushing fluid flows out of the hollow pipe a under the action of the three-way valve b, so that the flushing of an affected part is realized.
In view of the above-mentioned related art, the inventor found that the aspirator in the related art has no backflow prevention function, so that when the aspirator is finely dissected under a endoscope, a local majority of effusion can be removed through the aspirator, but because the aspirator must be closed in time in order to maintain the intra-abdominal pressure, a small amount of effusion remains in the hollow tube a; when the hollow tube a is flushed, flushing fluid also needs to flow out through the hollow tube a, so when the three-way valve b controls the hollow tube a to stop absorbing fluid, negative pressure is closed, part of effusion can remain in the hollow tube a, and when the hollow tube a is flushed, the flushing fluid passes through the hollow tube a, so that the effusion remaining in the hollow tube a flows back to the abdominal cavity along with the flushing fluid, thereby enhancing the possibility of influencing the visual field and causing infection and reducing the suction and flushing efficiency.
