Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an imaging device and endoscope system with recognition function. Background Technology

[0002] An endoscope is an instrument used for medical examinations and surgeries. It can be inserted into the human body through natural orifices or through minimally invasive incisions, allowing doctors to directly observe the internal condition of the patient.

[0003] An endoscopic system typically includes an endoscope and an imaging device. The imaging device includes a camera and a camera unit. The endoscope is inserted into the body of the patient to acquire optical information and transmits this information to the camera. The camera converts the optical information into electrical signals, which are then transmitted to the camera unit. The camera unit uses imaging algorithms to process the electrical signals into image information, allowing the user to observe the patient's internal condition. To meet different observation needs, endoscopes come in various types and specifications. For example, different endoscopes are used in joint surgery and spinal surgery. The imaging device and the endoscope are generally connected in a detachable manner, allowing the same imaging device to be used with different endoscopes, thus reducing the cost of using the endoscopic system.

[0004] However, after changing to different endoscopes, users need to visually identify the model and specifications of the endoscope and then manually switch the imaging algorithm of the imaging device to obtain better image processing results. This makes the operation of the endoscope system complicated and prone to errors. Utility Model Content

[0005] The main purpose of this invention is to propose an imaging device and endoscope system with identification function, which aims to identify the model and specifications of the endoscope and improve the ease of use of the endoscope system.

[0006] To achieve the above objectives, the present invention proposes an imaging device with recognition function, comprising a camera and a camera host, wherein the rear end of the camera is plugged into the camera host, the camera host includes a main control circuit board, and the imaging device further includes:

[0007] A connecting component, located at the front end of the camera, is used for detachable connection with an external endoscope;

[0008] Antenna, disposed on the connection assembly; and

[0009] A reader / writer is located on the camera host, and the reader / writer is electrically connected to the antenna and the main control circuit board respectively;

[0010] The reader / writer is used to send radio frequency signals to the endoscope through the antenna to trigger the electronic tag of the endoscope to emit identification information. The reader / writer is also used to receive the identification information through the antenna and transmit it to the main control circuit board.

[0011] In one embodiment, the connection component includes:

[0018] A photosensitive element is disposed inside the assembly cavity and electrically connected to the main control circuit board;

[0019] The photosensitive element is fixedly connected to the rear end of the connecting structure.

[0020] In one embodiment, the antenna is fixed to the photosensitive element.

[0021] In one embodiment, the photosensitive element includes a photosensitive circuit board and a photosensitive sensor disposed on the front side of the photosensitive circuit board.

[0024] In one embodiment, the outer rear wall of the connecting structure is snapped and fixed to the inner wall of the assembly cavity.

[0025] This utility model also proposes an endoscope system, including an endoscope and the aforementioned imaging device with recognition function, wherein the endoscope and the camera are detachably connected via the connecting assembly; the endoscope system further includes:

[0026] An electronic tag is attached to the endoscope and is configured to record identification information of the endoscope.

[0027] The imaging device with recognition function in this utility model includes a camera and a camera host. The rear end of the camera is plugged into the camera host, which includes a main control circuit board. The imaging device also includes a connecting component, an antenna, and a reader / writer. The camera receives light signals transmitted by the endoscope and converts them into electrical signals, which are then transmitted to the main control circuit board. The main control circuit board uses an imaging algorithm to process the electrical signals into image information, allowing the user to observe the internal condition of the object being observed.

[0047] This invention proposes an imaging device with recognition function.

[0048] Please see Figures 1 to 2 , Figure 1 This is a schematic diagram of an embodiment of the imaging device with recognition function provided by this utility model. Figure 2 for Figure 1 A magnified view of a portion of point A in the middle.

[0049] In one embodiment of this utility model, the imaging device with recognition function includes a camera 100 and a camera host. The rear end of the camera 100 is plugged into the camera host, which includes a main control circuit board 200. The imaging device also includes:

[0050] The connecting component 300 is located at the front end of the camera 100 and is used for detachable connection with the external endoscope 600.

[0051] Antenna 400 is disposed on connector 300; and

[0052] The reader 500 is located on the camera host and is electrically connected to the antenna 400 and the main control circuit board 200 respectively.

[0053] The reader 500 is used to send radio frequency signals to the endoscope 600 through the antenna 400 to trigger the electronic tag 700 of the endoscope 600 to emit identification information. The reader 500 is also used to receive the identification information through the antenna 400 and transmit it to the main control circuit board 200.

[0054] The imaging device with recognition function in this utility model includes a camera 100 and a camera host. The rear end of the camera 100 is plugged into the camera host, which includes a main control circuit board 200. The imaging device also includes a connection component 300, an antenna 400, and a reader / writer 500. The camera 100 receives the light signal transmitted by the endoscope 600 and converts the light signal into an electrical signal, which is then transmitted to the main control circuit board 200. The main control circuit board 200 uses an imaging algorithm to process the electrical signal into image information, allowing the user to observe the internal condition of the observed object. The camera 100 is detachably connected to the endoscope 600 via the connection component 300, enabling the imaging device to interface with different endoscopes 600. The antenna 400 on the connection structure 310 can receive the identification information from the endoscope 600 and transmit it to the reader 500. The reader 500 reads the identification information and transmits it to the main control circuit board 200, which then switches the imaging algorithm. This allows the main control circuit board 200 to identify different models and specifications of the endoscope 600 and automatically adjust the imaging algorithm for each model and specification to obtain the best image effect. Users do not need to identify the model and specification of the endoscope 600 by visual inspection, nor do they need to manually switch the imaging algorithm on the main control circuit board 200. This reduces the difficulty of using the endoscope system, avoids the problem of easily selecting the wrong imaging algorithm when manually adjusting it, and improves the ease of use of the endoscope system. On the other hand, the automatic adjustment of the imaging algorithm has a faster response speed than manual adjustment, which shortens the preparation time during surgery and reduces the surgical risk. In addition, the antenna 400 is located on the connection component 300, which is close to the endoscope 600 and also close to the electronic tag 700 on the endoscope 600 that is used to transmit identification information. This ensures effective transmission of wireless signals, reduces signal loss, and improves the response speed and accuracy when identifying the endoscope 600.

[0055] The antenna 400, reader 500, and electronic tag 700 together form a radio frequency identification module, also known as an RFID (Radio Frequency Identification) module. The antenna 400 enables contactless data communication between the reader 500 and the electronic tag 700 to identify the target. The electronic tag 700 is also called an RFID tag, transponder, or data carrier, while the reader 500 is also called a reader, reading device, scanner, reader head, or communicator. In this solution, the identification information of the endoscope 600 recorded by the electronic tag 700 refers to information indicating the current type of endoscope 600, which may include the endoscope 600's serial number, model, specifications, etc.

[0056] In one embodiment, the connection component 300 includes:

[0057] The connection structure 310 is located at the front end of the camera 100; and

[0058] Optical lens 320, one end of optical lens 320 is snapped into the front end of connecting structure 310, and the other end of optical lens 320 is snapped into endoscope 600;

[0059] The antenna 400 is located in the connection structure 310.

[0060] Reference Figure 2 In this embodiment of the invention, the connecting component 300 includes a connecting structure 310 and an optical lens 320. Both ends of the optical lens 320 are respectively snapped into the front end of the connecting structure 310 and the endoscope 600. The optical lens 320 achieves a detachable connection between the endoscope 600 and the camera 100 through snap-fit, improving the convenience of assembly and disassembly and facilitating the docking of the camera 100 with endoscopes 600 of different specifications and types. The antenna 400 is mounted on the connecting structure 310, making its arrangement and assembly relatively convenient, eliminating the need for structural adjustments to the optical lens 320, and reducing design complexity.

[0061] In another embodiment, the antenna 400 can also be arranged on the optical lens 320, so that the distance between the antenna 400 and the endoscope 600 is closer, further reducing signal loss and improving the response speed and accuracy when identifying the endoscope 600.

[0062] In one embodiment, the camera 100 is provided with an assembly cavity, the front end of the connecting structure 310 is snapped into the optical lens 320, the rear end of the connecting structure 310 is located inside the assembly cavity, and the antenna 400 is located at the rear end of the connecting structure 310.

[0063] Reference Figure 3In this embodiment of the present invention, the camera 100 is provided with an assembly cavity. The front end of the connecting structure 310 is detachably connected to the endoscope 600 by means of snap-fit ​​or bolt fastening. The rear end of the connecting structure 310 is located in the assembly cavity. The antenna 400 is located at the rear end of the connecting structure 310 and is also located in the assembly cavity. This allows the camera 100 to provide a certain degree of protection for the antenna 400 and extend the service life of the antenna 400.

[0064] In one embodiment, the camera 100 includes:

[0065] The housing 110 has an assembly cavity; and

[0066] The photosensitive element 120 is located inside the assembly cavity and is electrically connected to the main control circuit board 200. The photosensitive element 120 is used to receive the light signal acquired by the endoscope 600 and convert it into an electrical signal.

[0067] The photosensitive element 120 is fixedly connected to the rear end of the connecting structure 310.

[0068] Reference Figure 3 In this embodiment of the invention, the camera 100 includes a housing 110 and a photosensitive element 120. The housing 110 has an assembly cavity, and the photosensitive element 120 is located in the assembly cavity and electrically connected to the main control circuit board 200. The photosensitive element 120 converts the light signal captured by the endoscope 600 into an electrical signal and then transmits it to the main control circuit board 200. The photosensitive element 120 is fixedly connected to the rear end of the connecting structure 310, which can be achieved by snap-fitting, screw fastening, or other methods. During assembly, the photosensitive element 120 is first fixed to the rear end of the connecting structure 310, and then the connecting structure 310 is assembled with the housing 110, which improves the convenience of assembly. In addition, since the connecting structure 310 is connected to the endoscope 600, fixing the photosensitive element 120 to the connecting structure 310 makes it easier to align the photosensitive element 120 with the endoscope 600, reducing the problem of misalignment between the photosensitive element 120 and the endoscope 600, thereby improving the image quality.

[0069] In one embodiment, the antenna 400 is fixed to the photosensitive element 120.

[0070] Reference Figure 3 In this embodiment of the present invention, the antenna 400 is fixed to the photosensitive element 120 by means of welding, gluing, screw fastening, etc. The antenna 400 alone is small in size. However, in this embodiment, during assembly, the antenna 400 is first installed on the larger photosensitive element 120, and then the photosensitive element 120 is fixed to the rear end of the connecting structure 310. This allows the antenna 400 to be assembled with the connecting structure 310, which improves the convenience of assembly and helps to improve the structural compactness of the camera 100 and reduce the volume occupied.

[0071] In one embodiment, the photosensitive element 120 includes a photosensitive circuit board 121 and a photosensitive sensor (not shown) disposed on the front side of the photosensitive circuit board 121. The front side of the photosensitive circuit board 121 is fixedly connected to the rear end of the connection structure 310, and the antenna 400 is fixed to the front side of the photosensitive circuit board 121.

[0072] Reference Figure 3 In this embodiment of the present invention, the photosensitive element 120 includes a photosensitive circuit board 121 and a photosensitive sensor on the front side of the photosensitive circuit board 121. The photosensitive circuit board 121 is fixedly connected to the rear end of the connecting structure 310, which can be achieved by snap-fit, screw fastening, or other methods. During assembly, the front side of the photosensitive circuit board 121 is first fixed to the rear end of the connecting structure 310, and then the connecting structure 310 is assembled with the housing 110, which improves the convenience of assembly. In addition, since the connecting structure 310 is connected to the endoscope 600, fixing the photosensitive circuit board 121 to the connecting structure 310 makes it easier to align the photosensitive sensor with the endoscope 600, reducing the problem of misalignment between the photosensitive sensor and the endoscope 600, thereby improving the imaging quality.

[0073] In one embodiment, the camera 100 further includes a signal transmission line 130, which connects the photosensitive circuit board 121 and the reader 500. The antenna 400 is electrically connected to the photosensitive circuit board 121, and the reader 500 acquires identification information through the photosensitive circuit board 121 and the signal transmission line 130.

[0074] Optionally, the signal transmission line 130 is connected to the main control circuit board 200, and the main control circuit board 200 is connected to the photosensitive circuit board 121. That is, the signal transmission line 130 is connected to the photosensitive circuit board 121 through the main control circuit board 200. In other words, the reader 500 obtains identification information sequentially through the antenna 400, the photosensitive circuit board 121, the main control circuit board 200, and the signal transmission line 130.

[0075] Reference Figure 3 In this embodiment of the present invention, the photosensitive circuit board 121 of the photosensitive element 120 is connected to the reader 500 through the signal transmission line 130. The antenna 400 is not only physically fixed to the photosensitive circuit board 121, but also electrically connected to the photosensitive circuit board 121. This allows the identification information of the endoscope 600 received by the antenna 400 to be transmitted to the signal transmission line 130 through the photosensitive circuit board 121, and then to the reader 500 through the signal transmission line 130. There is no need to set up additional lines to connect the antenna 400 and the reader 500, which reduces the number of parts, reduces assembly steps, and reduces the manufacturing cost of the endoscope system.

[0076] In one embodiment, the rear end of the connecting structure 310 is provided with a receiving slot, and the antenna 400 is disposed inside the receiving slot.

[0077] Reference Figure 3 In the embodiments of this utility model, the rear end of the connecting structure 310 is provided with a receiving groove corresponding to the shape of the antenna 400. The antenna 400 is hidden in the receiving groove, which improves the structural compactness and avoids the antenna 400 occupying the assembly cavity space. The structural and layout changes of the components in the assembly cavity of the existing camera 100 are small, which makes it convenient to modify the existing camera 100.

[0078] In one embodiment, the outer rear wall of the connecting structure 310 is engaged and fixed to the inner wall of the assembly cavity.

[0079] In the embodiments of this utility model, the outer wall of the rear end of the connecting structure 310 is fixed to the inner wall of the assembly cavity by snap-fit ​​or convex-concave structure, so that the connecting structure 310 and the housing 110 are fixed together. The structure is simple, and no screws, adhesives or other fasteners are required. The assembly and disassembly are convenient and quick, which improves the assembly efficiency of the camera 100 and facilitates the maintenance of the camera 100.

[0080] Reference Figure 1 and Figure 4 This utility model also proposes an endoscope system, including an endoscope 600 and the aforementioned imaging device with recognition function, wherein the endoscope 600 is detachably connected to the camera 100; the endoscope system further includes:

[0081] An electronic tag 700 is attached to the endoscope 600 and is configured to record identification information of the endoscope 600.

[0082] The specific structure of the imaging device with recognition function is as described in the above embodiments. Since this endoscope system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0083] The endoscope system includes an endoscope 600, an electronic tag 700, and an imaging device with identification function. The endoscope 600 is inserted into the body of the object to be observed to obtain optical information, and then the optical information is transmitted to the camera 100. The camera 100 converts the optical information into electrical signals and transmits them to the main control circuit board 200. The main control circuit board 200 uses an imaging algorithm to process the electrical signals into image information, so that the user can observe the internal condition of the object. The system includes an electronic tag 700 on the endoscope 600 that records its identification information. An antenna 400 is mounted on the camera 100. When the reader 500 sends a radio frequency signal to the electronic tag 700, the tag emits identification information. The antenna 400 receives this information and transmits it to the reader 500, which then reads and transmits it to the main control circuit board 200. This allows the main control circuit board 200 to switch imaging algorithms, enabling it to recognize different models and specifications of endoscopes and automatically adjust its imaging algorithm for each model to achieve the best image quality. Users do not need to visually identify the model or specifications of the endoscope 600 or manually switch the imaging algorithm on the main control circuit board 200, reducing the difficulty of using the endoscope system and avoiding the problem of incorrect algorithm selection during manual adjustment, thus improving the ease of use. Furthermore, automatic algorithm adjustment is faster than manual adjustment, shortening preparation time and reducing surgical risks.
