Description

 Trachea distal probe structure improvement  

The invention relates to an improved structure of a distal endoscope of a bronchoscope, which mainly comprises a camera lens, an instrument tube, and a distal end of the illuminant having a reliable positioning and a stable combined state, and in the potting and packaging, ensuring each component There is no displacement between them, and a consistent combination structure is obtained. The bronchoscope can simplify the process during the manufacturing process and achieve effective positioning, improve production efficiency and yield, and achieve safe and reliable relative working position when used.

The general bronchoscopes have a similar basic design, including a tube body, which is provided into the cavity of the human body, and a lens module is provided by using the distal probe to capture the actual condition in the human body cavity, and the internal transmission line is used. The signal is sent to the external host for interpretation by the operator. There is another instrument tube for the operator to insert the small instrument into the body cavity and directly perform the operation. The structure of the distal probe is known as Chinese patent. Application No. 200980156440.3 "Method of Endoscope with Camera Housing and Method of Manufacturing Camera Case", which uses a mold set to form a space, and then inserts the camera module and other components into the space inside the mold. In addition, a T-shaped object is used to connect the instrument tube, and after the relevant components are placed, the glue filling process is performed, and after being solidified, it is integrated into one body. However, when the prior art is implemented, there is no firm combination between the components. Therefore, when filling the glue, it is often caused by the strong pressure generated during the pouring, and the process is also prone to potential displacement due to the inherent elasticity of the material, resulting in the offset of each member, and irrigation The solid glue positioning time is time-consuming, causing the product to have a high probability. In addition to the non-conformity, it may cause different positioning angles, affecting the user's routine judgment, and causing potential risks in medical use. Therefore, there is still a need for improvement.

The invention is an improved structure of a distal endoscope of a bronchoscope, which mainly comprises a camera module, an instrument tube, and a distal probe of the illuminator having a stable combined state, and in the filling and packaging, ensuring no between the components Displacement, a consistent combination of configurations, providing a bronchoscope for safety purposes. The distal probe comprises a hollow outer tube and an end panel which is combined with the outer end of the hollow outer tube, and the outer end of the instrument tube and the lens and the illuminator of the camera module are engaged on the end plate In the opposite hole, the components are brought into an extremely stable joint state, and then the front and rear of the hollow outer tube are subjected to a waterproof potting packaging procedure, thereby completing the perfect construction of the distal probe, and finally combining the outer end of the endoscope of the bronchoscope The rear end of the outer tube, that is, the overall structure of the bronchoscope, has excellent economy and significant practicality.

Referring to the drawings, the present invention is a structural improvement of a distal endoscope of a bronchoscope, characterized in that the distal probe of the bronchoscope comprises a hollow outer tube (1) and an end panel (2), the end panel (2) The outer end of the hollow outer tube (1) is assembled, and the end panel (2) is provided with an instrument hole (21), a mirror hole (22), and two light holes (23), and the end panel (2) The inner side of the instrument hole (21) is provided with two fixing seats (24). When assembled, the outer end of the instrument tube (3) is buckled to the instrument hole (21) and is a two fixing seat (24). The lens (41) of the camera module (4) is combined at the mirror hole (22). When used, the front edge of the mirror hole (22) can be additionally provided with a stepped groove to combine The waterproof lens (42) is external to the lens (41), and the illuminant (43) on both sides of the front end of the camera module (4) is also engaged in the opposite optical hole (23) of the end panel (2). The components are brought into an extremely stable joint state, and then the glue sealing process is performed by the front and rear of the hollow outer tube (1) to complete the perfect construction of the distal probe, and finally the outer end of the tube body (5) of the bronchoscope is The waterproof method is combined with the inner end of the hollow outer tube (1)

With the above combined device, the present invention can ensure that the distal probe including the camera module, the instrument tube, and the illuminator has a stable bonding state before the potting package is applied, so that when the glue is packaged, Ensure that the components are not displaced between each other, and that the distal probe structure of the consistent combination structure is obtained, and the bronchoscope can be provided for optimal safety when used. In summary, the present invention can provide an innovative combination structure, and the process process thereof is more simplified, and the economical requirements of mass production can be achieved, and the practical value thereof can be improved.

The openings on the end plate shown in the specification of the present invention are only provided in accordance with the position and shape of the lens, the illuminant, and the instrument tube on the camera module, that is, the shape or the number shown in the figure of the embodiment of the present invention. It is not intended to limit the scope of the present invention. In the spirit of the present invention, a distal probe structure which is fixedly bonded to each member by an end panel and then potted and encapsulated is covered by the patent of the present invention.
