Tracheoscopy

The invention is an innovative design of a bronchoscope, and mainly provides an ingenious and stable combined structure, which can effectively control the effect of oscillating bending and positioning of the distal end of the bronchoscope by means of a simpler operation mode, and enhance the camera module. It has the practicality of being combined with the illuminant in the probe.

It is known that the structure of the bronchoscope usually comprises a handle provided with a control mechanism, and one end is combined with an elongated catheter for extending into the human body, and the distal end of the catheter is combined with a probe containing a camera module for shooting people. The image in the body cavity is transmitted to the external screen for medical personnel to directly observe or perform therapeutic behavior. In order to obtain images of different angular positions inside the human body, a flexible hose portion is arranged at the distal end of the catheter, and the control is utilized. The mechanism operates the two pull wires to control the hose swing and to steer the probes together to obtain multiple different angles of the intracavity image. The design of such a bronchoscope including the control mechanism, the bending structure of the hose portion, and the configuration of the distal probe are different, but the convenience and practicality are still not used in use, such as the conventional bending control structure. When the operation is to bend the distal end of the catheter to the position, the position of the bending angle of the catheter must be ensured by the manual force by the hand to secure the positioning of the catheter, so there is still doubt of displacement, or again, with the locking In the setting of the mechanism, it is necessary to press a clamping mechanism to lock the button, and when it is necessary to change the angle of the distal end of the catheter, the second hand is required to operate the unlocking action separately. Inevitably, it causes inconvenience and troubles in use, and it is difficult to achieve the one-handed operation. In addition, the conventional structure for bending the distal end of the catheter is mostly formed by using a combination of a plurality of unit bodies to form a The swingable support body is housed in the hose portion, but the manufacturing of the structure is time-consuming and the processing is rather troublesome, and the combination of the control hose bending is not necessarily smooth, and once one of the unit bodies fails, the whole cannot be Reuse, it is not practical; and for the remote probe combined with the internal camera module and the illuminator and other components, and the way to reserve the working hole, the conventional method uses a mold to place the components first, but not at the exit end. With the normal configuration of positioning, when the internal components lack effective positioning design, the camera module, the illuminator, or the working hole offset phenomenon often occurs, which causes the product to be defective or malfunctioning, which is not conducive to The accuracy of the operation and the long glue time are too long, so the known bronchoscope design is necessary for improvement.

The invention relates to a bronchoscope, which mainly provides an innovative designer who can easily control the movement of the two pull wires inside the bronchoscope catheter, and the pivoting and bending of the distal end of the catheter, and to easily position the angle thereof. The overall structure includes a combination The handle of the control mechanism is connected at one end to a plug-in screen, and the other end is combined with a catheter. The distal end of the catheter is provided with a hose portion having a main elastic coil inside, and the most distal end is combined with an internal camera module. The probe of the group and the illuminator has two pull wires in the catheter, and the proximal end is extended and coupled to the control mechanism, and the distal end thereof is respectively disposed in the two small elastic coils and fixed; when used, the upper handle can be used The control piece moves the two pull wires in the previous movement mode to change the relative position, thereby achieving the purpose of bending the hose end portion of the catheter end and the probe in different directions, and can easily position the distal probe of the catheter at the angle. In addition, the hose part can be smoothly bent laterally under the cooperation of the main elastic spring ring and the two small elastic spring rings, and the probe design can be stable and precise. Bonding the light emitting structure and the like of the camera module The improved bronchoscope provided by the present invention has remarkable progress such as easy operation and stability of photographing.
