Endoscopic camera module fine structure

The present invention is a microscopic structure of an endoscope camera module, and mainly provides a simplified camera module with waterproof and reduced structural thickness, and replaces the focusing operation with a rear end movable sensor chip plate, so that the whole body has a very small volume. With its extremely small size, the endoscope can use a smaller diameter tube body, increase and facilitate the application range of medical surgery, and reduce the impact on the human body, and can be easily applied to the disposable endoscope device. , with practical progress.

In order to observe the diagnosis or treatment of organs inside the human body, the design of endoscopes has made significant progress in modern medicine. Among them, endoscopes with different functions have been developed for different organs of the human body, such as gastroscopy, laparoscopy, and hysteroscopy. Etc. to correspond to the needs of different organs. Generally, the endoscopes have similar basic designs, including a tube body, which is provided into the cavity of the human body, and has a camera module at the end thereof for taking the actual condition in the human body cavity, and sending the signal through the internal transmission line. To the external host position, the signal is converted into a readable image for the operator to interpret, wherein the tube body and the lens module are provided to extend into the human body, so the thickness thereof is felt to the patient during surgery or postoperative. Healing has considerable influence. The conventional endoscope is based on the purpose of repeated use. The tube body still has a large volume under the configuration of the existing camera module, and its diameter is usually larger than 10mm, mainly due to the conventional camera. The structure of the module, as shown in Fig. 1, usually includes a lens holder (1), a lens barrel portion (2) is combined at the upper portion thereof, and the body portion (3) and the lens group (4) are packaged. Covered inside, an inner rim is provided on the upper edge of the body portion (3) to prevent the outermost waterproof lens of the lens group (4) from falling off the outside of the camera module. It is cumbersome and cannot effectively reduce its volume and diameter, but has room for improvement.

The present invention is a microscopic structure of an endoscope camera module, and mainly provides a simplified camera module different from the lens of the conventional camera module. The structure only includes a body portion, and the waterproof plastic lens is directly used at the front end to waterproof the lens. There are several concentrating lenses to form optical imaging. The bottom can use the movable image sensor chip board. After adjusting the focus position to confirm the focusing range, it can be fixedly attached to the body of the tube and extended outward with the wire. In the past, with the larger focusing effect of the traditional lens barrel and the lens holder, the thickness of the mechanism was reduced and the waterproof function was achieved once, so that the overall camera module has a very small volume, and the tube body combined with the endoscope can be used. The front end, with its extremely small size, can greatly reduce the position of the endoscope opening, or use a smaller diameter tube to gain more space to provide porous endoscope applications, facilitate the implementation of medical surgery, and the human body The impact of wound wounds is lower, which is economical due to the simplification of the structure, and can be easily applied to future disposable endoscope devices. Further induced by practicality.

Please refer to Figure 2 first, this creation is a subtle camera module The invention mainly provides a simplified camera module, which comprises a tube body (5), a lens group (6) accommodated therein, and an image sensor wafer board (7), wherein the lens group ( 6) The outermost end is a waterproof lens (61), and a recessed portion (611) is provided on the outer surface layer. When the package is sealed, the waterproof glue (8) will fall into the recessed portion (611), so that the body portion (5) and the body portion (5) The waterproof lens (61) directly achieves a stable bond and achieves a sealing effect; other concentrating lenses (62) are sequentially arranged inside the body portion (5), and the bottommost position is combined with an image sensor. The wafer board (7), the image sensor wafer board (7) is first adjusted to the focus position to confirm the focus range, and then fixed in the waterproof rubber (8) package and fixed to the body portion (5) to obtain a predetermined camera. In the focal length range, the rear end is further extended by the wire (71). In this configuration, the lens barrel and the lens holder can be saved due to the focusing process, the pairing problem is caused by the tolerance of the tooth gauge, and the thickness of the lens barrel can be reduced. That is, the creation uses a single-layer body to directly replace the lens barrel, without the lens holder fitting, and instead uses the image sensor to make it into Focus focus, reducing the outer diameter module, providing a whole is the camera module distinct from a simplified conventional lens imaging module. Since the present invention has a very small volume in the case of using only the most basic components, the use of a smaller diameter tube for the endoscope can be facilitated by the application of the medical instrument. During surgery, the impact on the human body is reduced and it is beneficial for postoperative healing. In addition, since the structure of the creation is simplified, the components are few, and the production is easy, so the economic value is extremely high, and the use rate of the disposable endoscope device can be improved by the lower cost to avoid cross infection. The risk is one of the best news for modern medical care.

In summary, this creation can provide an innovative simplified structure, changing the focusing mode of the traditional lens barrel and the lens holder in the past, and reducing the thickness of each mechanism and achieving the waterproof function. The overall camera module has a very small volume, which can be applied to the front end of the tube body of the endoscope, and the minimum position of the endoscope can be greatly reduced or matched by the extremely small volume thereof. Use smaller diameter tubes to gain more space for porous endoscope applications, improve the scope of implementation of medical procedures, and reduce the impact of traumatic wounds on the human body to achieve further practicality.
