Description
Technical Field
The utility model relates to the field of medical appliances, in particular to a double-operation-channel bronchoscope alveolar lavage sleeve. Is used for bronchoscope anti-pollution alveolar lavage and dual operation channels.
Background
In the prior art, bronchoscopes enter the lower respiratory tract nasally or orally, and can carry microorganisms of the upper respiratory tract into the lower respiratory tract. The bronchoscope is provided with only one biopsy channel, and the injection of anesthetic, the removal of secretion of the atmospheric channel and the like in the process of entering the airway of the bronchoscope can cause the alveolar lavage fluid of the target lung segment to be polluted; meanwhile, most of the therapeutic instruments cannot pass through a biopsy channel with the diameter of 2mm of the bronchoscope, so that the operation is not smooth, and the cooperative operation of the two instruments cannot be realized.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a double-operation-channel bronchoscope alveolar lavage sleeve which can reduce the pollution caused by bronchoscope use and is beneficial to the cooperative operation of two instruments.
The technical solution of the utility model is as follows: the double-operation channel bronchoscope alveolar lavage sleeve is characterized by comprising a main pipe and an auxiliary pipe which are arranged in parallel, wherein the front end of the main pipe is a closed end, the closed end is provided with nicks which can be separated to two sides after being stressed, and the rear end of the main pipe is provided with an opening; the back end of the secondary pipe is provided with a main opening and a side opening externally connected with negative pressure, the main opening is covered by soft rubber, the center of the main opening is provided with a linear notch, and the front end of the secondary pipe is provided with an opening.
In the above scheme, the method further comprises:
the front end of the auxiliary pipe is a bevel pipe structure with a low outer part and a high inner part.
The outer surfaces of the main pipe and the auxiliary pipe and the connected side walls are provided with nicks convenient for axial splitting.
The utility model has the advantages that: adopt and be responsible for and the auxiliary line uses simultaneously, avoid bronchoscope alveolar lavage by upper airway, the pollution of atmosphere way microorganism, the inspection bronchoscope biopsy pore is only 2mm, solves most apparatus (need 3mm pore) and gets into tracheal difficult problem, realizes that bronchoscope inspection can't realize two apparatus interoperations, has greatly expanded the scope of bronchoscope operation.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Detailed Description
Referring to fig. 1, the part names are as follows: a main pipe 1, an auxiliary pipe 2, a main opening 3, a side opening 4 and a nick 5.
Referring to fig. 1, the double-operation channel bronchoscope alveolar lavage cannula comprises a main tube 1 and an auxiliary tube 2 which are arranged side by side, wherein the front end of the main tube 1 is a closed end, the closed end is provided with nicks 5 which can be separated to two sides after being stressed, and the rear end of the main tube 1 is opened; the back end of the secondary pipe 2 is provided with a main opening 3 and a side opening 4 externally connected with negative pressure, the main opening 3 is covered by soft rubber, the center of the main opening is provided with a straight notch, and the front end opening of the secondary pipe 2 is an inclined plane pipe structure with a low outside and a high inside. The outer surfaces and the adjacent side walls of the main pipe 1 and the auxiliary pipe 2 are provided with nicks convenient for axial splitting.
The double-operation channel bronchoscope alveolar lavage sleeve is of a sterile double-tube structure. The main tube 1 has various specifications, such as the diameter of 3.1mm, 4.1mm and 5.9mm, the length is 60cm according to the external diameter of the used bronchoscope, a small amount of sterile enzyme removal lubricant is arranged in the tube cavity, the transparent material at the front end is completely sealed, and the transparent material is provided with nicks and can be separated towards two sides after being stressed. The accessory pipe 2 is the soft tubular structure of internal diameter 3mm, its partial inner wall is for being responsible for outer wall (disjunctor structure), the front end is outer low interior high down's down tube structure (avoiding damaging the air flue), the rear end is two open structures, the external negative pressure of accessory pipe side opening 4 attracts, main opening 3 has soft rubber to cover, there is a style of calligraphy incision in the center (keeping open-ended seal when inserting the apparatus), can insert appliances such as scope spray line, biopsy forceps, Argon Plasma Coagulation (APC) pipeline and cryoprobe. The outer side walls and the connected side walls of the main pipe 1 and the auxiliary pipe 2 are provided with nicks, the main pipe and the auxiliary pipe can be cut open and taken out when necessary, and instruments (such as a saccule) in the auxiliary pipe 2 are left in the air passage. The main pipe 1 and the auxiliary pipe 2 are made of plastic materials.
The use method or the working principle is as follows: this application is double-barrelled structure, and the person in charge 1 overlaps on the bronchoscope of the same external diameter. Before operation, an endoscope spraying pipe is inserted into the main opening 3 of the auxiliary pipe in advance, and the side opening 4 of the auxiliary pipe is externally connected with negative pressure suction. When the endoscope is put in through the nose or the mouth to the glottis, the endoscope spraying tube extends out of the auxiliary tube 2, 1-1.5ml of 2% lidocaine is respectively sprayed to pear-shaped fossae at two sides for surface anesthesia, and the endoscope spraying tube is retracted into the auxiliary tube 2. After the bronchoscope enters the trachea, the endoscope spraying pipe stretches out of the auxiliary pipe 2 and sprays 2% lidocaine to perform surface anesthesia on the trachea and the branch bronchus, and after the surface anesthesia of the airway is completed, the endoscope spraying pipe is pulled out. The bronchoscope arrives near lavage bronchus mouth in advance, keeps being responsible for 1 rigidity, and propelling movement bronchoscope forward makes its front end break suddenly and is responsible for 1 outer 1-2cm, and the bronchoscope is aseptic state this moment, inlays the bronchoscope front end and pauses in lavage bronchus mouth, carries out the lavage operation through the biopsy pore of bronchoscope, can guarantee that the lavage liquid sample that obtains is not contaminated. The main opening 3 of the auxiliary tube 2 can be matched with instruments in a biopsy duct of the bronchoscope through biopsy forceps, an APC pipeline, a cryoprobe, a balloon and the like to complete the required matching operation.
In the embodiment 1, a cryoprobe is inserted into a biopsy channel of a bronchoscope to carry out frozen biopsy, a balloon is preset in the auxiliary tube 2, if heavy bleeding occurs, the balloon can be quickly inserted into a bleeding bronchus to be pressurized and compressed for hemostasis, if long-time compression hemostasis is needed, the main tube 1 and the auxiliary tube 2 can be cut open along the nicks on the outer surface and the connected side wall and taken out, and the balloon is left in the bronchus.
In the embodiment 2, the small ultrasonic probe is inserted into the biopsy channel of the bronchoscope, and the TBNA puncture needle is inserted into the auxiliary tube 2, so that the wall penetrating biopsy of the focus at the far end of the lower bronchus is guided by ultrasound at any time, and the problem that the ultrasonic bronchoscope body is thick and cannot reach the upper lobe, the lobe bronchus and the branch of the far-end bronchus is solved.
The foregoing description is only exemplary of the utility model and is not intended to limit the spirit of the utility model.
