By adopting the structure, the inserting part, the bending part and the front end part can not damage the inner wall of the bronchus when rotating or moving forwards; the bending part and the front end part can rotate or move freely, so that the inspection effect is improved; once complications occur on the inner wall of the bronchus or during operation, if the complications occur, drainage can be thoroughly performed; the foreign body in the air passage can be successfully completed by the method; can ensure the safe operation of patients with complicated illness for a long time.

Description

A compound flexible bronchoscope

technical field

The invention relates to a bronchoscope, in particular to a soft bronchoscope.

Background technique

In the current prior art, a flexible bronchoscope includes an operating part, an insertion part, a bending part, a front end, an eyepiece arranged on the operating part, and a light guide connecting part connected with the operating part. The problem is: when in use, the insertion part, the bending part and the front end are located in the bronchus, and the insertion part and the bending part move or rotate in the bronchus, which is easy to cause trauma to the inner wall of the bronchus; in order to ensure the effect of the inspection, the insertion part and the Insertion after disinfection of the curved part increases the chance of trauma many times; once complications occur on the inner wall of the bronchus or during the operation, if a large one occurs, there will be serious consequences; foreign bodies in the airway cannot be completed by traditional methods; complex conditions require a longer period of time. Time operation patients can not tolerate.

Contents of the invention

The purpose of the present invention is: to provide a composite soft bronchoscope, which can be inserted or taken out multiple times to prevent trauma to the bronchi; the curved part and the front end can be easily disinfected and cleaned, and the curved part and the front end can be moved or rotated Freedom; once complications occur on the inner wall of the bronchus or during the operation, if a large one occurs, it will be completely drained; foreign bodies in the airway can be successfully completed with this method; it can ensure safe operation for patients with complicated conditions for a long time.

The present invention is realized in the following way: a composite soft bronchoscope, including an operation part, an insertion part, a bending part, a front end, an eyepiece arranged on the operation part and a light guide connecting part connected with the operation part, its special The method is: it also includes a catheter sleeve made of metal material, and the catheter sleeve includes a straight pipe and an oxygen delivery interface arranged at the operation part of the straight pipe;

In use, the insertion part is located in the straight pipe, and the bending part and the front end protrude from the end of the insertion end of the straight pipe; there is a gap between the insertion part, the bending part and the front end and the inner wall of the straight pipe.

The composite soft bronchoscope described above is special in that: the oxygen supply interface has an acute angle with the operating part of the straight tube.

The composite flexible bronchoscope is characterized in that: the acute angle between the oxygen delivery interface and the operating part of the straight tube is 40-45 degrees.

The composite flexible bronchoscope is characterized in that the distance between the intersection of the oxygen supply interface and the straight tube is 5-10 cm from the end of the operation part.

A composite flexible bronchoscope of the present invention adopts such a structure. When in use, the straight tube of the catheter sleeve is first inserted into the bronchus and reaches the predetermined position, and then the insertion part, the bending part and the front end are separated from the straight tube of the catheter sleeve. The operation part of the tube is inserted, and the part of the insertion part, the curved part and the front end protrude from the lower end of the straight tube; when the insertion part, the curved part and the front end rotate or move forward, there will be no damage to the inner wall of the bronchi; due to the bending The head and the front end can rotate or move freely, which improves the inspection effect; once complications occur on the inner wall of the bronchus or during the operation, if a large one occurs, it will be completely drained; foreign bodies in the airway can be successfully completed with this method; Time safe operation.

Description of drawings

Fig. 1 is a front view of the present invention.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1, a compound flexible bronchoscope includes an operation part 1, an insertion part 2, a bending part 3, a front end part 4, an eyepiece 5 arranged on the operation part 1 and a light guide connected to the operation part 1 Connecting part 6.

It also includes a catheter sheath 7 made of metal material, said catheter sheath 7 includes a straight tube 71 and an oxygen delivery interface 72 arranged at the operation part 711 of the straight tube; the oxygen delivery interface 72 can be connected with a ventilator. The oxygen delivery interface 72 is 5 centimeters away from the operating part.

During use, the insertion part 2 is located in the straight tube 71, and the curved part 3 and the front end 4 stretch out from the end of the insertion end of the straight tube 71; There are gaps between the inner walls.

The oxygen delivery interface 72 has an acute included angle with the operation part of the straight pipe 71 . The included angle is 40-45 degrees.

The distance between the intersection of the oxygen delivery interface 72 and the straight pipe 71 is 5-10 cm from the end of the operation part 711 .

What has been described above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make some improvements and modifications without departing from the principle of the present invention, which are also considered as the protection scope of the present invention.
