Description

An electronic endoscope assembly and intracranial examination system Technical Field

[0001] This utility model relates to the field of medical instrument technology, and in particular to an electronic endoscope assembly and an intracranial examination system. Background Technology

[0002] An endoscope is a specialized medical instrument that can be used to examine or treat internal diseases through natural cavities or tiny incisions in the human body. With the development of microelectronics technology, electronic endoscopes are being used more and more widely in medicine.

[0003] The STORZ endoscope, widely used in current neurosurgical endoscopy, has a main structure that includes an optical system (front-mounted), a cold light source, an image sensor, and a processor located at the rear (in the handpiece and external devices). The front-mounted optical system is the lens end, which is about 250mm long, while the processor is located at the rear, including the handpiece and external devices. The STORZ endoscope has a large and heavy overall structure and many complex external devices. Because the image sensor is not limited by the diameter of the lens end, it has the structural advantage of high definition, but its procurement cost is high.

[0004] Existing endoscopes are rigid, resulting in poor freedom of observation angle and range. Different models (such as 0°, 30°, 70°, etc.) are often required to achieve the surgical purpose. They cannot be seamlessly connected with surgical microscopes, and one must be removed before another can be used.

[0005] Furthermore, existing endoscopes are heavy, making them difficult to control and secure when performing deep and delicate procedures by hand; they also require a high level of skill from surgeons; their complex structure, numerous external devices, and large space requirements during surgery further complicate the process. Information acquisition still relies on physical storage for copying and transferring data, lacking an independent port and the ability to synchronously exchange information during surgery.

[0055] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0056] Example 1

[0057] As shown in Figures 1-2, an electronic endoscope assembly provided by this utility model includes: a camera module and a connecting operation tube unit.

[0058] As shown in Figures 3-4, the camera module includes: a lens, a circuit board 105, and multiple LED lights 103.

[0059] The lens includes a miniature objective lens 101 and a CMOS image sensor 112. The miniature objective lens 101 is positioned at the front end of the camera module, and the CMOS image sensor 112 is positioned at the rear end of the miniature objective lens 101. Multiple LED lights 103 are arranged around the miniature objective lens 101. Optical adhesive 102 is filled around the front edge of the miniature objective lens 101 and around the multiple LED lights 103. The LED lights 103 are front-facing light sources, providing illumination to the detection area in the confined space inside the human body.

[0060] The CMOS image sensor 112 and LED 103 are electrically connected to the circuit board 105. The circuit board 105 adopts an FPCBA module, which is a flexible circuit board that carries the fingerprint chip and other electronic components. The lens and the circuit board 105 are disposed within a PEEK terminal 104 (PEEK terminal refers to a terminal made of polyetheretherketone material); the space between the PEEK terminal 104 and the circuit board 105 is filled with filler adhesive 106. The miniature objective lens 101 of this invention completes optical imaging and projects it onto the CMOS image sensor 112; the CMOS image sensor 112 collects light signals, converts them into digital signals through AD (analog-to-digital conversion), and then outputs the signals for display and storage by the image processor 2 at the next level. To ensure the realization of this invention, the model of the CMOS image sensor 112 is given as an example, OV9734. The front is the photosensitive surface, which can receive the image from the miniature objective lens 101; the back is the soldering surface, where the solder joints of the CMOS image sensor 112 are melted and soldered onto the solder pads of the circuit board 105, thereby realizing the circuit connection.

[0061] The connecting operation tube unit of this utility model includes a medical heat shrink tubing 107, a shaping tube 108, and a plastic tube 109 arranged sequentially from the outside to the inside; the medical heat shrink tubing 107 is connected to the end of the PEEK terminal 104; the shaping tube 108 and the plastic tube 109 are connected to the end of the filling adhesive 106. Connecting wires can run inside the plastic tube 109.

[0062] The connecting operation tube unit of this utility model adopts a composite tube with a three-layer structure of malleable tube; the plastic tube 109 contains a tightly wound spring steel wire; the shaping tube 108 contains a galvanized iron wire; the plastic tube 109 and the shaping tube 108 have different elasticities, and the force of their gaps cancels each other out when bending, so as to achieve the purpose of shaping; the outermost layer is a medical heat shrink tube 107, which conforms to medical materials, can pass biocompatibility tests, and can be used in medical applications.

[0063] This invention employs a flexible circuit board (FPCBA module) and a composite tube with a three-layer structure of a malleable tube for connecting the operating tube unit, enabling this invention to realize a flexible and malleable endoscope.

[0064] As shown in Figure 5, an endoscope connector is provided at the end of the connecting operation tube unit. The endoscope connector includes: a connecting operation tube connector 110 and an adapter plate 111; the connecting operation tube connector 110 is installed at the end of the connecting operation tube unit; the adapter plate 111 is disposed inside the connecting operation tube connector 110, the adapter plate 111 is electrically connected to the circuit board 105, and the connecting wire between the adapter plate 111 and the circuit board 105 is placed in the plastic tube 109.

[0065] The working principle of the electronic endoscope assembly of this utility model is as follows: Using the connecting operation tube unit, the shape is adjusted according to the specific conditions and angles of the area to be explored during surgery. Under the illumination of the LED light 103, the miniature objective lens 101 is used to closely observe the lesion. The miniature objective lens 101 completes optical imaging and projects it onto the CMOS image sensor 112. The CMOS image sensor 112 collects the light signal and converts it into an electrical signal. The CMOS image sensor 112 transmits the electrical signal to the microchip on the circuit board 105 for decoding. The decoded electrical signal is then transmitted to the adapter board 111, so that the adapter board 111 can transmit the electrical signal to the next-level image processor 2.

[0066] Example 2

[0067] As shown in Figure 6, the electronic endoscope assembly provided in this embodiment is basically the same as that in Embodiment 1, except for the structure of the camera module; specifically, the miniature objective lens 101, the CMOS image sensor 112, and the LED light 103 are all tilted; the miniature objective lens 101 and the connecting operation tube unit form an angle of 20-50°, preferably 30°. Tilting the miniature objective lens 101 allows the electronic endoscope assembly of this embodiment to adapt to different detection environments. The specific angle can be adjusted and selected according to actual conditions.

[0068] Example 3

[0069] As shown in Figure 7, this utility model also provides an intracranial examination system, including: an image processor 2, a controller 3, and an electronic endoscope assembly 1 provided in any embodiment of this utility model.

[0070] The electronic endoscope assembly 1 is electrically connected to the image processor 2;

[0071] The image processor 2 is electrically connected to the controller 3; or the image processor 2 and the controller 3 are integrated together. The controller 3 can be a tablet or mobile phone for convenient operation. The controller 3 can also be connected to a networked display or AR glasses.

[0072] Specifically, the electronic endoscope assembly 1 and the image processor 2 are connected by a connecting cable 4; one end of the connecting cable 4 is provided with a connector cap 401, and the other end is provided with a first TYPE-C plug 402; the connector cap 401 is connected to the connecting operation tube connector 110; the first TYPE-C plug 402 is connected to the image processor 2.

[0073] As shown in Figure 8, the image processor 2 includes: an image processor upper shell 201, a shielding upper shell 202, an image processing board 203, a shielding lower shell 204, and an image processor lower shell 205. The image processing board 203 is disposed within the shielding upper shell 202 and the shielding lower shell 204, which are fastened together. The shielding upper shell 202 and the shielding lower shell 204 are disposed within the image processor upper shell 201 and the image processor lower shell 205, which are fastened together. A second Type-C connector 206 is provided on the output line of the image processor 2, and the second Type-C connector 206 is connected to the controller 3.

[0074] The working process of this intracranial examination system is as follows: The electrical signals collected by the electronic endoscope component 1 are transmitted to the image processor 2, which transcodes them (making them recognizable by the controller 3). The transcoded electrical signals are then transmitted to the controller 3 (a tablet or mobile phone), which in turn transmits the signals to a display or AR glasses to convert them into real-time surgical images. Simultaneously, data interconnection, local storage, real-time remote information interaction, and cloud uploading are possible. After the neurosurgeon completes the craniotomy, a natural air medium channel to the intracranial lesion is created. Using the electronic endoscope component 1, it is shaped according to the surgical needs to closely observe dark areas in the surgical field that are inaccessible to the surgeon's naked eye or surgical microscope. If the required observation angle for the dark area is still not achieved after shaping with a 0° flexible endoscope, a 30° flexible endoscope is used for further shaping (the overall observation angle after shaping with a 30° endoscope can exceed 90°), thus completing dynamic observation. After clarifying the lesion, a snake-shaped retractor can be used to fix the shaped endoscope, allowing the surgeon to perform surgical operations with both hands to treat the lesion.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
