Description

Technical Field

[0001] The present invention relates to the field of bronchoscopes, and more particularly to a system for improving the visibility of a fiberoptic bronchoscope. Background Art

[0002] Traditional optical fiber bronchoscopes are widely used in clinical practice, such as bronchoscopic airway secretion cleaning, bronchoscopic foreign body removal, bronchoalveolar lavage, and drug injection for tumor treatment. However, due to the small diameter of the eyepiece, the operator needs to observe the endoscopic field of view with one eye, resulting in a poor visualization experience. For bystanders, they cannot see the endoscopic image at the same time as the operator during the operation, making it difficult to perform teaching, image recording, and other operations.

[0003] With the development of science and technology, electronic fiber bronchoscopes have greatly improved visualization and can achieve high-definition visualization images. However, they are more expensive than traditional optical fiber bronchoscopes. Especially in many medical institutions, where optical fiber bronchoscopes are already available and can continue to be used without damage, replacing them with electronic fiber bronchoscopes will cause a huge waste of medical resources. Therefore, it is necessary to reasonably improve the visualization of traditional optical fiber bronchoscopes, which can improve the visualization experience of operators and bystanders, while reducing the waste of medical resources caused by the replacement of fiber bronchoscopes. Summary of the invention

[0011] A further technical solution is that the first adjustment mechanism includes a first threaded rod fixed on the outer arc surface of the moving part along the length direction of the accommodating hole, the other end of the first threaded rod passes through the hole wall of the accommodating hole and is sleeved with a nut matching it, and a threaded hole matching the thread of the first threaded rod is opened at the penetration.

[0012] A further technical solution is that the second adjustment mechanism includes a second threaded rod fixed at the bottom of the moving plate and perpendicular thereto, the threaded rod passes through the adjustment hole and is locked by a nut matching its thread.

[0013] A further technical solution is that the third adjustment mechanism is fixed to a third threaded rod on the movable plate at one end in a direction perpendicular to the length of the main frame plate, a sliding guide mechanism is fixed at the connection between the movable plate and the clamping plate, the other end of the third threaded rod passes through the reverse extension part of the raised end of the clamping plate and is locked by a nut, a threaded hole matching the thread of the third threaded rod is provided at the penetration part, and the length of the reverse extension part does not exceed the thickness of the movable plate.

[0020] In actual operation, various adjustment mechanisms are used to change and rotate the connectable area of ​​the card-connecting part, so as to meet the needs of placing different types of mobile terminals and facilitate access anywhere in real life.

[0021] After fixing the mobile terminal, the position of the mobile terminal camera can be freely adjusted through the adjustment mechanism and fixed above the eyepiece of the bronchoscope, reducing the movement of the field of view; the bronchoscope operation visual device can move freely with the operator's hand movements, and at the same time the mobile phone camera is adjusted to the fixed focus mode, thereby avoiding the inconvenience of repeatedly adjusting the camera position.
