[0040] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be noted that

[0041] like Figure 1 As shown, an endoscope camera system 1000 is provided in one embodiment, and the endoscope camera system 1000 includes a light source 10, a light guide 20, a rigid tube endoscope 30, an optical mount 40, a camera 50, an endoscope camera communication cable 81, a camera host 60, a display 70 and a video connection cable 82. The camera host 60 is connected to the camera 50 via the endoscope camera communication cable 81, and the image signal obtained by the camera 50 is transmitted to the camera host 60 via the endoscope camera communication cable 81 for processing. In some embodiments, the endoscope camera communication cable 81 can be an optical communication cable, such as an optical fiber; the camera 50 converts the image signal (electrical signal) into an optical signal, which is transmitted to the camera host 60 via the endoscope camera communication cable 81, and the camera host 60 then converts the optical signal into an electrical signal. The camera host 60 is connected to the display 70 via the video connection cable 82 for sending the video signal to the display 70 for display. It should be understood by those skilled in the art that Figure 1 The endoscopic camera system 1000 is merely an example and does not limit the endoscopic camera system 1000. The endoscopic camera system 1000 may include Figure 1 More or fewer components, or combinations of certain components, or different components may be shown. For example, the endoscopic camera system 1000 may also include a dilator, a smoke control device, input and output devices, a network access device, etc.

[0042] The light source 10 is used to provide an illumination source to the observed area 100. The illumination source includes a visible light source and a laser illumination source (such as near-infrared light) corresponding to a fluorescent agent. The light source 10 includes, but is not limited to, a laser light source, an LED light source, or a laser diode.

[0043] In this embodiment, the light source 10 includes a visible light source and a laser light source corresponding to the fluorescent reagent. The visible light source is an LED light source. In one embodiment, the visible light source can provide multiple monochromatic lights of different wavelength ranges, such as blue light, green light, red light, etc. In other embodiments, the visible light source can also provide a combination of the multiple monochromatic lights, or a wide-spectrum white light source. The wavelength range of the monochromatic light is approximately 400nm to 700nm. The laser light source is used to generate laser. The laser is, for example, near infrared light (NIR). The peak wavelength of the laser is at least one value within the range of 780nm or 808nm.

[0044] Since the light source 10 can simultaneously provide continuous visible light and laser light corresponding to the fluorescent agent to the part to be observed, the efficiency of the camera 50 in collecting visible light image signals and fluorescent image signals reflected by the part to be observed 100 is improved.

[0045] Prior to imaging using the endoscopic camera system 1000, a contrast agent, such as indocyanine green (ICG), is introduced into the observed area 100 via intravenous or subcutaneous injection. This allows for imaging of tissue structures and functions (e.g., blood, lymph, and bile in vessels) that are not easily visualized using standard visible light imaging techniques. The observed area 100 includes, but is not limited to, the circulatory system, lymphatic system, and tumor tissue. ICG, commonly known as indocyanine green, diagnostic green needle, or indocyanine green, is a contrast agent commonly used in the clinical diagnosis of cardiovascular diseases and is widely used for imaging choroidal and retinal blood vessels. When the contrast agent in the observed area 100 absorbs the laser light generated by the laser light source corresponding to the fluorescent agent, it produces fluorescence.

[0046] An endoscope camera communication cable 81 is provided in one embodiment. This application uses a rigid tube endoscope camera communication cable as an example for explanation. This endoscope camera communication cable can also be used on a flexible endoscope.

[0047] like Figure 1 and Figure 2 As shown, the endoscope camera communication cable 81 of this embodiment includes a first connector 1, a connecting wire 2, a second connector 3 and a shielding ring 4. The two ends of the connecting wire 2 are respectively connected to the first connector 1 and the second connector 3. The first connector 1 is used to connect to the camera 50, and the second connector 3 is used to connect to the camera host 60. The shielding ring 4 is installed in the first connector 1.

[0048] like Figure 5 As shown, the first connector 1 includes a first front sleeve 11, a first rear sleeve 12 and a first connecting terminal 13. The first front sleeve 11 and the first rear sleeve 12 are snapped together. The first front sleeve 11 and the first rear sleeve 12 can also be an integrated structure. In some embodiments, the first rear sleeve 12 can also be omitted.

[0049] like Figure 2 and Figure 3 As shown, one end of the first connection terminal 13 is exposed from the first front sleeve 11, and the other end is fixed to the first front sleeve 11 via solid glue 11a. An interface 13a is provided on the end of the first connection terminal 13 exposed from the first connection terminal 13. One end of the connecting wire 2 is inserted into the first front sleeve 11 from the end away from the first connection terminal 13. The end of the connecting wire 2 inserted into the first front sleeve 11 extends to connect with the first connection terminal 13. The end of the first front sleeve 11 on which the first connection terminal 13 is mounted is adapted to fit into the mounting seat 511 of the handle 51. The first front sleeve 11 is designed to be inserted into the mounting seat 511 of the handle 51, and the end of the first connection terminal 13 exposed from the first connection terminal 13 extends into the accommodating cavity of the handle 51. The interface 13a of the first connection terminal 13 is used to connect to the chip module 52 in the handle 51 via a transition cable 53.

[0050] An annular groove is provided on the outer surface of the first front sleeve 11, and a sealing ring 15a is installed in the annular groove. The sealing ring 15a is clamped between the mounting seat 511 of the handle 51 and the first front sleeve 11, so as to prevent water from entering the accommodating cavity of the handle 51 from between the mounting seat 511 of the handle 51 and the first front sleeve 11.

[0051] The shielding ring 4 is installed in the first front sleeve 11 and is sleeved on the connecting line 2. The shielding ring 4 is a magnetic ring. The shielding ring 4 forms a magnetic field in the first front sleeve 11. The shielding ring 4 is a pre-selected magnetic material, so that the shielding ring 4 shields the interference signal from interfering with the transmission signal of the connecting line 2, thereby improving the signal transmission quality of the endoscope camera communication cable 81. At the same time, the shielding ring 4 is installed in the first connecting terminal 13, and the accommodating cavity of the handle 51 does not need to be provided with a space to accommodate the shielding ring 4, thereby reducing the volume of the handle 51 and making it convenient for the doctor to hold the handle 51 for operation.

[0052] The shielding ring 4, one end of the first connecting terminal 13, and the end of the connecting wire 2 are all fixed to the first front sleeve 11 by solid glue 11a. The shielding ring 4 is encapsulated by the solid glue 11a within the first front sleeve 11, forming an integrated fixed structure with the first front sleeve 11. In the prior art, the shielding ring 4 is installed in the accommodating cavity of the handle 51, usually fixed by a mounting seat, which can easily cause the shielding ring 4 to loosen. Compared to the prior art, the shielding ring 4 of the present application is built into the first connecting terminal 13, which is structurally stable and will not loosen.

[0053] To better encapsulate the shielding ring 4, the first connecting terminal 13, and the connecting wire 2, an annular groove 11b is provided at one end of the first front sleeve 11 near the first connecting terminal 13. The solid glue 11a extends to fill the annular groove 11b, so that the fixed glue forms a structure with an annular protrusion. The solidified solid glue 11a will be stuck in the annular groove 11b through the annular protrusion, limiting the axial freedom of the solid glue 11a, ensuring that the encapsulated shielding ring 4, the first connecting terminal 13, the connecting wire 2, and the solid glue 11a will not slide axially out of the first front sleeve 11. In other embodiments, an annular protrusion, or several independent smaller protrusions or grooves, are provided in the first front sleeve 11, which can also serve as an axial limit.

[0054] To better secure the connecting cable 2, a ferrule 14 is installed at the end of the first front sleeve 11 away from the first connecting terminal 13. This ferrule 14 is positioned between the first front sleeve 11 and the connecting cable 2. The ferrule 14 locks the connecting cable 2 within the first front sleeve 11, preventing it from loosening. The ferrule 14 also has an annular groove, within which a sealing ring 15b is installed. This sealing ring 15b is squeezed between the ferrule 14 and the first front sleeve 11, preventing water from entering the first front sleeve 11 along the connecting cable 2.

[0055] In this embodiment, a locking hole is provided at the end of the first front sleeve 11 away from the first connecting terminal 13, and a locking screw 16 is installed in the locking hole. The locking screw 16 is squeezed on the outer wall of the ferrule 14, and the locking screw 16 locks the ferrule 14 and the connecting wire 2 in the first front sleeve 11.

[0056] In other embodiments, one end of the first connecting terminal 13 is fixed in the first front sleeve 11 by solid glue 11a, the connecting wire 2 is clamped in the first front sleeve 11 by the ferrule 14, and the two ends of the shielding ring 4 are respectively against the sealing end face of the sealed first connecting terminal 13 and the end face of the ferrule 14, which can also secure the first connecting terminal 13, the ferrule 14 and the shielding ring 4 in the first front sleeve 11.

[0057] In this embodiment, a narrowed mounting portion is provided on the outer surface of one end of the first front sleeve 11 away from the first connecting terminal 13, and one end of the first rear sleeve 12 is inserted into the mounting portion of the first connecting terminal 13. A groove and a protrusion are provided on the mounting portion of the first connecting terminal 13, and a corresponding protrusion and groove are provided on the inner surface of the first rear sleeve 12. The first rear sleeve 12 is snapped onto the first front sleeve 11 through elastic deformation.

[0058] The first rear sleeve 12 is narrowed internally at one end away from the first front sleeve 11, and an axial table is formed at the narrowed portion. The narrowed hole can only accommodate the connecting line 2. The first front sleeve 11 and the ferrule 14 are inserted into one end of the first rear sleeve 12, and the end portions of the first front sleeve 11 and the ferrule 14 are both against the table at the narrowed portion of the first rear sleeve 12. The first rear sleeve 12 forms an axial limit for the first front sleeve 11 and the ferrule 14, further preventing the ferrule 14 and the connecting line 2 from falling out.

[0059] In this embodiment, the second connector 3 has the same structure as the first connector 1. The second connector 3 includes a second front sleeve, a second rear sleeve and a second connecting terminal. The end of the connecting wire 2 away from the first connector 1 is connected to the second connecting terminal. The second front sleeve and the second rear sleeve are clamped together. The second connecting terminal and the end of the connecting wire are fixed in the second front sleeve, and the second rear sleeve plays a further axial fixing role.

[0060] In other embodiments, the second connector 3 can also be set to a structure different from the first connector 1. For example, the second connector 3 is only a clip-on component, which clips the connecting line 2 to the camera host 60, and the connecting line 2 is directly connected to the mainboard of the camera host 60.

[0061] like Figure 4 As shown, in one embodiment, an endoscopic camera system 1000 is provided. The camera head 50 of the endoscopic camera system 1000 includes a handle 51 and a chip module 52. The handle 51 has a receiving cavity with openings at both ends, and the openings at both ends are connected to the receiving cavity. A front cover is installed at one end of the opening of the handle 51, and the chip module 52 is installed in the receiving cavity of the handle 51 and is installed on the front cover.

[0062] like Figure 6As shown, a mounting seat 511 is provided on the other opening of the handle 51. The mounting seat 511 has a mounting hole, and the mounting hole of the mounting seat 511 is connected to the accommodating cavity of the handle 51. The first connector 1 of the endoscope camera communication cable 81 is inserted into the mounting hole of the mounting seat 511. The first connection terminal 13 of the first connector 1 is located in the accommodating cavity of the handle 51. The first connection terminal 13 is connected to the chip module 52 via a transition cable 53.

[0063] In this embodiment, the mounting base 511 and the handle 51 are an integrated structure. In other embodiments, the mounting base 511 can be fixedly connected to the handle 51 by means of threads or snap connections.

[0064] The chip module 52 includes components such as sensors and processors. The chip module 52 is used to convert optical signals into electrical signals, and after processing the electrical signals, transmit them to the camera host 60 for processing through the endoscope camera communication cable 81.

[0065] like Figure 5 and Figure 6 As shown, in one embodiment, to better secure the endoscope camera communication cable 81, a locking sleeve 512 is connected to the end of the mounting seat 511. One end of the locking sleeve 512 is clipped onto the end of the mounting seat 511, and the endoscope camera communication cable 81 is inserted into the locking sleeve 512. The inner hole of the locking sleeve 512 near the mounting seat 511 is provided with a narrowing portion. This narrowing portion is a mounting hole with a smaller inner diameter, thereby forming a table at the narrowing portion. The outer circumference of the first front sleeve 11 near the end of the second rear sleeve 12 also has a narrowing portion, and the narrowing portion of the first front sleeve 11 also forms a table. The narrowing portion of the first front sleeve 11 is clamped into the narrowing portion of the locking sleeve 512. The table of the locking sleeve 512 is blocked by the table of the first front sleeve 11, thereby locking the first front sleeve 11 in the mounting seat 511.

[0066] In one embodiment, an annular groove is provided on the outer circumference of the mounting seat 511, and a sealing ring 513 is installed in the annular groove. The sealing ring 513 is pressed between the mounting seat 511 and the locking sleeve 512, and can prevent water from entering the accommodating cavity of the handle 51 from between the mounting seat 511 and the locking sleeve 512.

[0067] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention.
