Background

The bronchus endoscopy is a commonly used examination and treatment means in the department of respiration, is gradually applied to the department of anesthesia, intensive care and rehabilitation, and has the following significance: the diagnosis of airway diseases, the positioning of a double-cavity bronchial catheter or a plugging tube, the treatment of pulmonary inflammation bleeding, the removal of airway foreign matters and the like. In the operation process of the bronchial endoscope, the clear operation visual field is very important. In the past, when the visual field is not clear due to excessive secretion or bleeding in the air passage during the operation of the bronchoscope, the secretion or blood in the operation visual field is sucked by adopting a suction method so as to make the visual field clear. However, since the lens and the suction port of the conventional bronchoscope are on the same plane, the lens is easily contaminated during the suction process, which results in an unclear visual field, and document No. CN 204072031U discloses an endoscope with a cleaning function, in which when the lens is contaminated and the image cannot be clearly displayed, the lens is cleaned by a cleaning pump, thereby ensuring smooth operation, but the cleaning process makes the work of medical staff cumbersome, thereby delaying the examination time.

As shown in fig. 1 to 4, the present embodiment provides a bronchial endoscope having a lens contamination prevention airway insertion portion, which includes a housing 1, an airway insertion portion 2, and a cable 3, wherein the airway insertion portion 2 and the cable 3 are fixed at the lower end of the housing 1. The outside of casing is equipped with control lever 4, suction joint 5 and suction control valve 6, suction joint 5 connects the negative pressure pump, still be equipped with operation passageway 7 in the casing 1, operation passageway 7's end sets up as the inlet the top of casing 1, the stirring of control lever 4 can make the crooked position of air flue insertion portion 2 crooked, and control air flue insertion portion 2 rotates.

The air flue inserting part 2 is internally provided with a working channel 2-1, the end part of the working channel 2 is provided with a miniature probe 2-2, the working channel 2-1 extends out of the air flue inserting part 2, and the extending part 2-3 is longer than the miniature probe 2-2, so that the extending part 2-3 can be clearly seen in a picture shot by the miniature probe 2-2, and the extending part 2-3 is made of flexible elastic materials, such as silica gel and the like, as shown in figure 4, the tail end of the extending part 2-3 of the working channel 2-1 extending out of the air flue inserting part 2 is arc-shaped, and only 1 sputum suction port 2-5 is arranged at the tail end of the extending part 2-3. As shown in fig. 3, a transparent protective cover 2-4 is arranged at the tail end of the air passage insertion part 2 along the outer edge, the outer diameter of the protective cover 2-4 is equal to that of the air passage insertion part 2, and the protective cover 2-4 just can cover the extending part 2-3 of the working channel 2-1, so that the protective cover 2-4 does not obstruct the visual field of the miniature probe and can protect a patient from being injured; the miniature probe 2-2 is electrically connected with the cable 3 through a camera and is provided with an illumination light source, and an anti-fogging layer is arranged at the position of the lens. The operation channel 7 is communicated with the working channel 2-1, and the tail end of the cable 3 is provided with a cable connector 3-1 for connecting an external display, so that medical staff can observe the internal condition of a patient conveniently.

The suction connector 5 is fixed on the side surface of the shell 1, the suction connector 5 is connected with the working channel 2-1 and is in control connection with the suction control valve 6, and the suction control valve 6 is a switch valve and can control the opening and closing of a passage between the suction connector 5 and the working channel 2-1. The suction control valve 6 is in a normally closed state and is turned to an open state only after being pressed.

The specific implementation process of this embodiment is as follows:

in the process of treating patients, medical staff need to use a bronchoscope to observe the airway condition and suck the airway secretion of the patients out. Before the medical staff uses, the cable connector 3-1 is connected with an external display to confirm whether the bronchoscope is normal in function, then the suction connector 5 is connected with the negative pressure pump, and the medical staff inserts the airway insertion part 2 into the lung of a patient to suck sputum or blood in the lung of the patient. Because sputum or blood is more viscous, and the working channel 2-1 is very thin, therefore the working channel 2-1 is often blocked, so when the working channel 2-1 is blocked, the working channel 2-1 can be flushed by injecting liquid into the operation channel 7 (when flushing, the working channel 2-1 needs to be moved out of a patient body firstly). After the flushing is finished, the air flue insertion part 2 is inserted into the lung of a patient, the suction operation is executed, during suction, medical staff judge the position of secretion through the miniature probe 2-2, the control rod 4 is used for controlling the air flue insertion part 2 to reach a specified position, then the extending part 2-3 of the working channel 2-1 is attached to the secretion, then the suction control valve 6 is opened to suck the secretion, and the secretion is relatively far away from the miniature probe 2-2 in the suction process, so that the miniature probe 2-2 cannot be polluted, and the miniature probe 2-2 cannot be blurred.

It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and the utility model only describe the principle of the present invention without departing from the spirit and scope of the present invention, the present invention can also have various changes and improvements, and these changes and improvements all fall into the scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
