Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a rigid bronchoscope. Background Art

[0002] The rigid bronchoscope, also known as a hard endoscope, is a medical device commonly used in modern medicine and is a very important tool for modern pulmonary interventional therapy. It is mainly used to examine the conditions inside the airway or the reaction of lesions outside the airway inside the airway. During the examination, a slender bronchoscope is inserted into the lower respiratory tract of the patient through the mouth or nose, that is, through the glottis into the trachea, bronchi and more distal parts, directly observing the lesions of the trachea and bronchi, and performing corresponding examinations and treatments according to the lesions. The existing structure of the rigid bronchoscope includes a lens tube. The lens tube is a rigid tube with a uniform diameter. The rear end (operating end) is provided with a main examination port, a ventilation port, a light source port and a jet ventilation port. The main examination port is used for the endoscope to pass through to examine the bronchi and lungs. With the rapid development of modern endoscope technology and the increase of integrated components, such as cameras and lighting, the light source port is used to introduce optical elements for illumination. This leads to functional duplication, and the light source port communicates with the main examination port and is blocked by a blocking cap. If the blocking cap is accidentally touched during operation, the mechanical ventilation of the ventilator will cause air flow disorder in the lens tube, posing a potential risk of aggravating the condition of the injured. In addition, the diameter of the lens tube is uniform, and the whole contacts the human tissue. It is inconvenient to discharge the blood at the front end of the lens tube, and the friction between the lens tube and the tissue causes damage to the human tissue. Therefore, it is necessary to improve the existing rigid bronchoscope to meet the treatment needs of patients. Summary of the Utility Model

[0003] In order to solve the problems existing in the prior art, the utility model provides a rigid bronchoscope to solve the problems of functional duplication at the operating end, damage to human tissue by the lens tube, and inconvenient bleeding guidance.

[0004] To solve the above problems, the technical solution of the utility model is as follows: A rigid bronchoscope includes an operating end and a lens tube. The operating end is located at one end of the lens tube. The other end of the lens tube is a beveled opening. The operating end is provided with a main examination port, a jet ventilation port, an auxiliary ventilation port and a blocking part. The main examination port is connected and communicated with the lens tube. The jet ventilation port, the blocking part and the auxiliary ventilation port are arranged on both sides of the main examination port. The jet ventilation port is connected and communicated with the main examination port. The blocking part is used as the force application point for inserting and removing the rigid bronchoscope.

[0005] Further, the diameter of the beveled opening end is larger than the diameter of the other end of the lens tube.

[0006] Further, a plurality of through holes are arranged on the front side wall of the lens tube.

[0007] Further, the auxiliary ventilation port is perpendicular to the lens tube and obliquely intersects and communicates with the jet ventilation port.

[0008] Further, the blocking portion is correspondingly arranged with the auxiliary ventilation port.

[0009] Further, it further includes an examination port plug for blocking the main examination port. A first through hole for the endoscope to pass through, prevent the endoscope from sliding violently, and reduce the air leakage of the mirror tube is provided on the examination port plug.

[0010] Further, it further includes a ventilation port plug for blocking the sealed injection ventilation port.

[0011] Further, a second through hole for the injection ventilator to pass through and reduce the air leakage of the mirror tube is provided on the ventilation port plug.

[0012] Compared with the prior art, the utility model has the following beneficial effects: The mirror tube communicates with the main examination port, reducing one light source port, having fewer interfaces, smooth inner walls, and stable air flow; The front end of the mirror tube can expand a larger space, providing a wider field of view for the endoscope. The diameter of the rear end is reduced, reducing friction with tissues, minimizing damage, and facilitating the drainage of blood at the front end. Description of the Drawings

[0017] As Figure 1 , Figure 2 , Figure 3 shown, a rigid bronchoscope includes an operating end 1 and a mirror tube 2. The operating end 1 is located at one end of the mirror tube 2. The other end of the mirror tube 2 is a bevel opening 3. A number of through holes 8 are provided on the front side wall of the mirror tube 2. When the mirror tube 2 is long, the through holes 8 can be provided. When it is short, the through holes 8 can be cancelled. A main examination port 4, an injection ventilation port 5, an auxiliary ventilation port 6 and a blocking portion 7 are provided on the operating end 1. It further includes an examination port plug 41 for blocking the main examination port 4. A first through hole for the endoscope to pass through, prevent the endoscope from sliding violently, and reduce the air leakage of the mirror tube 2 is provided on the examination port plug 41. It further includes a ventilation port plug 51 for blocking the sealed injection ventilation port 5. A second through hole for the injection ventilator to pass through and reduce the air leakage of the mirror tube 2 can be provided on the ventilation port plug 51, or a sealing plug can also be used. During use, the injection ventilator passes through the second through hole of the injection ventilation port 5; When the auxiliary ventilation port 6 is connected to a positive pressure ventilator, the injection ventilation port 5 can adopt a non-porous blocking cap to prevent air leakage.

[0018] The main examination port 4 is connected and communicated with the mirror tube 2. The jet ventilation port 5, the blocking part 7, and the auxiliary ventilation port 6 are arranged on both sides of the main examination port 4. The blocking part 7 is correspondingly arranged with the auxiliary ventilation port 6, which is convenient for grasping the blocking part 7 and the auxiliary ventilation port 6 when inserting and removing the rigid bronchoscope. The jet ventilation port 5 is connected and communicated with the main examination port 4. The auxiliary ventilation port 6 is perpendicular to the mirror tube 2, and is obliquely intersected and connected with the jet ventilation port 5. The blocking part 7 is the stress point for inserting and removing the rigid bronchoscope.

[0019] The diameter of the inclined plane opening end 3 is larger than the diameter of the other end of the mirror tube 2. The mirror tube 2 can adopt two sections of tube walls with different diameters. The diameter of the inclined plane opening 3 end of the mirror tube 2 is 15 mm, and the diameter of the other end of the mirror tube is 14 mm. It can also adopt a tube wall with a gradually decreasing diameter, that is, the wall thickness gradually decreases. The diameters of both ends of the mirror tube 2 can be adjusted according to actual needs. The front end of the mirror tube 2 can open up a larger space, making the endoscope vision more open. The diameter of the rear end is reduced, reducing friction with tissues, reducing damage, facilitating the drainage of blood at the front end, and making the operation more convenient.

[0020] The main examination port 4 allows the endoscope to pass through. The jet ventilation port 5 and the auxiliary ventilation port 6 are used to connect the ventilator. The blocking part 7 can replace the light source port, reducing an interface communicating with the mirror tube 2, reducing the air flow disorder in the mirror tube during mechanical ventilation of the ventilator, reducing the harm to the patient, and being used as a handle for the doctor to grasp during use, facilitating the insertion and removal of the rigid bronchoscope. The overall structure of this application is simple, the layout of each interface is reasonable, and the operation is simpler.
