Sucked type material taking device for bronchoscope

Abstract

The invention discloses a sucked type material taking device for a bronchoscope. The sucked type material taking device for the bronchoscope comprises a flexible sleeve tube and an adjustable telescopic negative pressure tube arranged in the flexible sleeve tube, a negative pressure suction cup which is contained in the flexible sleeve tube and capable of stretching out the front end of the flexible sleeve tube is connected to the front end of the adjustable telescopic negative pressure tube, and the tail end of the adjustable telescopic negative pressure tube stretches out of the tail end of the flexible sleeve tube and is connected with a negative pressure source. The sucked type material taking device for the bronchoscope is used in cooperation with the bronchoscope, is convenient to operate, spheroidal foreign matters with smooth surfaces embedded in a weasand can be taken out, the defects of an existing bronchoscope material taking device can be overcome, foreign matters in segment bronchia can also be taken out, thoracotomy is avoided, and the practicability is high.

Description

technical field [0001] The invention relates to the field of an object extractor for trachea foreign bodies, in particular to an object extractor for a sucker-type bronchoscope. Background technique [0002] Children are prone to inhale foreign bodies into the trachea when crying, eating while lying down, and playing with objects. Adults are prone to inhale foreign bodies into the trachea after alcoholism, coma, general anesthesia, swallowing insufficiency, and vomiting. Tracheal foreign body symptoms are usually related to the size, shape and nature of the foreign body. Patients in the acute stage may have symptoms such as cough, chest tightness, chest pain, and shortness of breath. In severe cases, suffocation or foreign bodies may induce laryngospasm and cause death. When the foreign body inflatable caliper is in one side of the bronchus, it can be wrapped by granulation or fibrous tissue, causing bronchial obstruction, causing secondary infection, etc., and also causing...

AI Technical Summary

Problems solved by technology

[0004] However, if the foreign body is a spherical foreign body such as iron beads, glass balls, plant nuts, etc., the surface of this type of foreign body is smooth and hard, not easy to break, and it is often close to the tracheal wall

Due to the shape of the foreign body and the fact that the foreign body is close to the wall of the trachea, the above-mentioned tracheoscopic object retrieval forceps 10 cannot easily clamp the foreign object, resulting in the failure of the object retrieval.

In addition, when the foreign body in the trachea is round and small in size, it tends to fall into the lobe bronchus easily. At this time, the retrieval forceps 10 of the bronchoscope cannot be opened because the forceps head 11 cannot be opened, resulting in the failure of retrieval.

Such patients need to obtain material through thoracotomy, which makes patients face huge surgical trauma and surgical risks
