[0066] The utility model discloses a camera device applied to a hard tube endoscope. The camera device is used in an endoscope system. For ease of understanding, a typical endoscope system is first described in conjunction with the accompanying drawings. Figure 1 The endoscope system 1 includes but is not limited to an endoscope light source host 10 , a light guide 20 , an external endoscope 30 , an imaging device 40 , an optical mount 41 , an endoscope camera host 50 and a display 60 .

For example, the endoscope system 1 may also include a dilator, a smoke control device, input and output devices, a network access device, etc.

[0068] In this embodiment, one end of the light guide 20 is connected to the light guide interface 11 of the endoscope light source host 10, and the other end of the light guide 20 is connected to the external endoscope 30. The light guide 20 is used to provide light for the external endoscope 30. One end of the camera device 40 is connected to the camera interface 51 of the endoscope camera host 50 through a communication cable to transmit the image signal obtained by the camera device 40 to the endoscope camera host 50 for processing. The other end of the camera device 40 is used to be connected to the external endoscope 30 to obtain the optical signal of the external endoscope 30.

[0069] The endoscope light source host 10 is used to provide an illumination light source to the observed part Z. The illumination light source includes a visible light illumination light source and a laser illumination light source corresponding to a fluorescent agent. The endoscope light source host 10 includes but is not limited to a laser light source, a visible light source or a laser diode.

[0070] The light guide 20 is located in the light output path of the endoscope light source main unit 10 and is connected to the external endoscope 30 to transmit the illumination light source generated by the endoscope light source main unit 10 to the observation site Z through the light guide 20 and the external endoscope 30 . The proximal end of the external endoscope 30 is connected to the camera device 40 through the optical bayonet 41 .

[0071] At least one image sensor is arranged in the camera device 40. The external endoscope 30 is used to transmit the illumination light source reflected by the part to be observed Z to the at least one image sensor. Specifically, the distal end of the external endoscope 30 includes an insertion portion inserted into the part to be observed Z. A lens assembly is arranged in the insertion portion. The external endoscope 30 is connected to the at least one image sensor in the camera device 40 through the lens assembly, so that the scene light reflected by the part to be observed Z is projected to the at least one image sensor through the lens assembly.

[0072] The image data acquired by at least one image sensor is image data in Bayer format. At least one image sensor is a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor. In this embodiment, at least one image sensor is used to alternately collect light signals (such as visible light image signals and fluorescent image signals) reflected by the part to be observed, thereby improving image acquisition efficiency. Wherein, the visible light image signal includes at least one of a blue light image signal, a green light image signal, and a red light image signal.

[0073] The endoscope system 1 also includes an image processor. In some embodiments, the image processor is disposed in the endoscope camera host 50. In other embodiments, the image processor may also be disposed in the camera device 40. In another embodiment, the external endoscope 30 and the camera device 40 may be an integrated electronic endoscope (e.g., a 3D electronic endoscope), and its image sensor is disposed at the head end of the external endoscope 30. The image processor is used to obtain visible light image signals and fluorescent image signals, and process the visible light image signals and the fluorescent image signals respectively to obtain corresponding visible light images and fluorescent images, and fuse the visible light images and the fluorescent images to output visible light images with fluorescent markers. The display 60 is used to display at least one of a visible light image, a fluorescent image, and a visible light image with fluorescent markers.

[0074] The first embodiment of the utility model discloses a camera device 1000 for a hard tube endoscope, referring to Figure 2 , this embodiment and Figure 1 The camera device 40 in the embodiment has differences, for example, Figure 1 The camera device 40 in the embodiment is a linear camera device, and the light transmitted by the external endoscope can pass through the channel in the camera device 40 along a straight line. However, the camera device 1000 in this embodiment is roughly an L-shaped structure, and the light transmitted by the external endoscope needs to turn inside the camera device 1000. Figure 2 The typical structure of the L-shaped camera device shown is as follows: the L-shaped camera device includes a fixed part and a handle part. The fixed part is connected by, for example, Figure 1The optical bayonet 41 in the L-shaped camera is connected to an external endoscope, and the handle part has an image sensor such as the aforementioned one. In actual use, the endoscope and the optical bayonet 41 will rotate according to the user's operation, resulting in that the light signal transmitted from the endoscope to the image sensor cannot be received by the image sensor in the correct direction, thereby causing the image displayed on the display to rotate, affecting the user's viewing. Based on this, the handle part of the current L-shaped camera device can rotate relative to the fixed part, thereby driving the image sensor to rotate to adjust the direction of the image displayed on the display, so that it is in the correct direction that is easy to view. In addition, the L-shaped camera device is also provided with a button, and the user can control the camera device to perform operations such as shooting through the button. At present, the buttons are all provided on the handle part of the L-shaped camera device. However, as mentioned above, the user needs to frequently operate the handle to rotate during use, which makes it easy to trigger the button by mistake, affecting the user's operation. Based on this, the camera device of this embodiment sets the button on the fixed part, so that the situation of button mis-triggering can be significantly reduced. The following will be explained in conjunction with specific embodiments and drawings.

[0075] Reference Figures 2 to 5 The camera device 1000 in this embodiment includes a connecting component 100, a button component 200, a handle component 300 and an optical component 400 (shown in FIG. Figure 5 ), wherein the connecting assembly 100 is used to install an external endoscope, the handle assembly 300 is used for the user to hold and / or manually adjust, the button assembly 200 can be triggered by the user to control the camera device 1000 to perform operations, and the optical assembly 400 is used to form an optical path.

[0076] Reference Figure 3 , Figure 4The connection assembly 100 includes a first connection component 110 and a second connection component 120 connected to each other, the first connection component 110 is connected to the handle assembly 300, and the second connection component 120 is used to detachably connect to an external endoscope. Specifically, the first connection component 110 includes a first section 111 and a second section 112 connected to each other, for example, the first section 111 and the second section 112 are connected to form an integral structure. The first section 111 is connected to the handle assembly 300, and the second section 112 is connected to the second connecting component 120. In the illustrated embodiment, the first section 111 and the second section 112 are connected through their respective ends. More specifically, the first section 111 is basically arranged in the vertical direction, and the second section 112 is basically arranged in the horizontal direction, so that the first section 111 and the second section 112 are basically perpendicular. It should be noted that the terms "basically arranged in the vertical direction", "basically arranged in the horizontal direction", and "basically vertical" appearing here and in other parts of the present invention are expressions considering processing capabilities, which include the situations of "arranged in the vertical direction", "arranged in the horizontal direction", and "vertical", as well as the situations of relatively strictly vertical state, strictly horizontal state, and strictly vertical state with a certain offset.

[0077] Reference Figure 5 , Figure 6 , Figure 6 The dotted line in the figure represents the optical axis of the optical element. The first section 111 has a first channel 113 inside, and the second section 112 has a second channel 114 inside. The first channel 113 and the second channel 114 are connected to each other. Taking the figure as an example, the first channel 113 and the second channel 114 are connected through their respective ends. More specifically, the first channel 113 is basically arranged in the vertical direction, and the second channel 114 is basically arranged in the horizontal direction, so that the first channel 113 is basically perpendicular to the second channel 114. The optical component 400 includes a first optical element 410 arranged in the first channel 113, and a second optical element 420 arranged in the second channel 114. The optical axis of the first optical element 410 is basically perpendicular to the optical axis of the second optical element 420.

[0078] It should be noted that the optical assembly 400 is not limited to the first optical element 410 and the second optical element 420. Figure 5 , Figure 6 As shown, the optical component 400 may further include a third optical element 430 disposed at the connection point between the first channel 113 and the second channel 114. The light signal transmitted from the endoscope passes through the first optical element 410 along a first direction (e.g., a horizontal direction), changes direction through the third optical element 430, and then passes through the second optical element 420 along a second direction (e.g., a vertical direction) to be transmitted to the image sensor.

[0079] It should also be noted that the cross-sectional shapes of the first channel 113 and the second channel 114 are adjusted according to the shape of the optical element. In the illustrated embodiment, the first channel 113 and the second channel 114 are both circular channels.

[0080] The handle assembly 300 includes a housing 310, which is connected to the first section 111 of the first connecting member 110, specifically to the lower end of the first section 111. Figure 4 , Figure 5 In the illustrated embodiment, the housing 310 is a split structure, which includes an upper housing 311 and a lower housing 312, which are fixed by welding, bonding, etc., for example, referring to Figure 4 The upper end surface of the lower shell 312 is provided with a circle of flange 3121 extending in the axial direction, the upper shell 311 is sleeved on the outer side of the flange 3121, the lower end surface of the upper shell 311 is bonded or welded to the upper end surface of the lower shell 312, and the shell 310 is provided as a split structure to facilitate the installation of other internal devices. In some further embodiments, a sealing structure is further provided between the upper shell 311 and the lower shell 312, for example, a sealing ring provided between the inner wall surface of the upper shell 311 and the outer wall surface of the flange 3121.

[0081] The handle assembly 300 also includes an image processing assembly 320, which may include the aforementioned image sensor. The image processing assembly 320 is housed in the inner cavity of the housing 310. In response to the triggering of the button assembly 200, the image processing assembly 320 receives the light signal transmitted by the optical assembly 400 and generates an image signal, which is transmitted to an external display to form an image. In this embodiment, the handle assembly 300 can be controlled by the user to move relative to the first connecting member 110, such as rotating, so as to realize the manual correction function of the image.

[0082] The key assembly 200 is electrically connected to the image processing assembly 320, so that the key assembly 200 can respond to the user's trigger and control the image processing assembly 320. It should be noted that the key assembly 200 can be electrically connected to the image processing assembly 320 in a contact or non-contact manner, which will be described in subsequent embodiments. Figures 2 to 5 The button assembly 200 is specifically arranged on the first connecting part 110. When the handle assembly 300 is driven by the user, the button assembly 200 and the first connecting part 110 can remain relatively still. In this embodiment, the button assembly 200 is arranged on the first connecting part 110 which is usually far away from the user's operating part, rather than the handle assembly 300, which can reduce the problem of false triggering caused by the user operating the handle assembly 300.

[0083] It should be noted that the button assembly 200 referred to in the present invention includes a trigger component, which can be triggered by a user to generate a control signal. The specific triggering methods include but are not limited to pressing, touching, rotating, pushing, etc. Accordingly, the trigger component can be a press trigger component, a touch trigger component, a rotate trigger component, or a push trigger component.

[0084] On the basis of the first embodiment, the camera device may further include other components, such as a focus component, the focus component includes an adjustment ring sleeved on the outside of the housing 310, for example, sleeved on the outside of the upper housing 311, the optical component 400 also includes a mounting ring, the first optical element 410 is integrated in the mounting ring, and as the adjustment ring rotates, the optical module formed by the mounting ring and the first optical element 410 can move along the axial direction of the housing 310, thereby achieving focus adjustment. As a specific implementation method of the adjustment ring driving the optical module to move axially, the outer side of the mounting ring has a driving shaft extending along the radial direction of the housing 310, the inner side of the adjustment ring has an oblique groove, the housing 310 has a guide groove arranged along the axial direction, the driving shaft passes through the guide groove and is inserted into the oblique groove, so that as the adjustment ring rotates, the driving shaft slides in the oblique groove on one hand and slides in the guide groove on the other hand, thereby causing the optical module to move axially.

[0085] On the basis of the first embodiment, the camera device may further include other components, such as a signal transmission component 500. The signal transmission component 500 in the embodiment of the utility model is electrically connected to the key component 200 and the image processing component 320, respectively, so as to realize the control of the image processing component 320 by the key component 200. In some embodiments, the signal transmission component 500 may be a wire or a flexible circuit board, and the two ends of the wire or the flexible circuit board are electrically connected to the key component 200 and the image processing component 320, respectively, by means of plug-in terminals or welding. In other embodiments, the signal transmission component 500 may also include multiple components. For details, refer to Figures 4 to 7The signal transmission component 500 includes a first transmission component 510 and a second transmission component 520. The first transmission component 510 is connected to the first connection component 110 and is electrically connected to the button component 200. The second transmission component 520 is connected to the handle component 300 and is electrically connected to the image processing component 320. When the user triggers the button component 200, the first transmission component 510 and the second transmission component 520 can transmit signals. As mentioned above, in order to realize the restoration of the picture, the handle component 300 will rotate frequently during use. The signal transmission component 500 of this embodiment includes two independent parts, the first transmission component 510 and the second transmission component 520. The first transmission component 510 is electrically connected to the button component 200 so that it can remain relatively still. The second transmission component 520 is electrically connected to the image processing component 320 so that it can rotate relative to the first transmission component 510 with the rotation of the handle component 300. In this way, the problems of wire entanglement and limited rotation range caused by the rotation of the handle component 300 can be avoided.

[0086] When the signal transmission component 500 includes a first transmission component 510 and a second transmission component 520, Figure 7 In some embodiments of the present invention, the first transmission component 510 includes a first conductor, the second transmission component 520 includes a second conductor, the first conductor and the second conductor are in contact with each other, and at least one of the first conductor and the second conductor is set as a ring structure, so that the first transmission component 510 can remain relatively still, and the first conductor and the second conductor can always remain conductive. It can be understood that, with the above structure, the first transmission component 510 and the button assembly 200 will both be stationary, and there is no relative movement between the two. The second transmission component 520 and the handle assembly move synchronously, and there is no relative movement between the two. The first transmission component 510 and the second transmission component 520 are conductive by contact, and there is no wire between the two. Therefore, the problem of wire winding can be completely solved, and the handle assembly can be rotated arbitrarily without any limitation on the rotation range.

[0087] by Figure 7 As shown in the example, the first conductor is an annular structure, the second conductor is a slider, and the second conductor can rotate along the circumference of the first conductor on the outside of the first conductor. As a specific way to achieve contact and conduction between the two, the outer peripheral surface of the first conductor is provided with at least one annular guide groove, and the second conductor is provided with a conductive needle corresponding to the guide groove, and the conductive needle is located in the guide groove and contacts the groove wall for conduction.

[0088] When the signal transmission component 500 includes a first transmission component 510 and a second transmission component 520, the signal transmitted between the first transmission component 510 and the second transmission component 520 in some embodiments of the present invention is an electrical signal. For example, when the first transmission component 510 and the second transmission component 520 are respectively the aforementioned first conductor and second conductor, the two are in contact and conductive, thereby transmitting the electrical signal.

[0089] When the signal transmission component 500 includes a first transmission component 510 and a second transmission component 520, other signals can also be transmitted for control. The first transmission component 510 and the second transmission component 520 can achieve signal transmission without contact. In other embodiments of the utility model, the signal transmitted between the first transmission component 510 and the second transmission component 520 is a magnetic field signal. Accordingly, the first transmission component 510 includes a magnetic field transmitting device, and the second transmission component 520 includes a magnetic field receiving device. In response to the triggering of the key component 200, the magnetic field transmitting device transmits a magnetic field signal to the magnetic field receiving device.

[0090] In some other embodiments of the utility model, the signal transmitted between the first transmission component 510 and the second transmission component 520 is an optical signal. Accordingly, the first transmission component 510 includes a light emitting device, and the second transmission component 520 includes a light receiving device. In response to the triggering of the key assembly 200, the light emitting device emits an optical signal to the light receiving device.

[0091] In some other embodiments of the utility model, the signal transmitted between the first transmission component 510 and the second transmission component 520 is an electromagnetic wave signal. Accordingly, the first transmission component 510 includes an electromagnetic wave transmitting device, and the second transmission component 520 includes an electromagnetic wave receiving device.

It can be understood that since the first transmission component 510 and the key assembly 200 remain stationary, the first flexible circuit board 530 will not be twisted. In this embodiment, the first transmission component 510 and the key assembly 200 are connected by the first flexible circuit board 530 whose length can be customized, and the installation position of the first transmission component 510 and the key assembly 200 may not be restricted by the first transmission component 510, so that the key assembly 200 can be set at a position that is unlikely to be accidentally triggered by the user as much as possible, for example, the first section 111 is away from the second end 1112 of the handle assembly 300.

[0094] When the signal transmission component 500 includes a first transmission component 510 and a second transmission component 520, Figure 4 and Figure 7 In some embodiments of the present invention, the signal transmission component 500 further includes a second flexible circuit board 540, and the second transmission component 520 is electrically connected to the image processing component 320 via the second flexible circuit board 540. It can be understood that since the second transmission component 520 and the image processing component 320 can move synchronously and remain relatively still, the second flexible circuit board 540 between the two will not be twisted due to the rotation of the handle component 300. In this embodiment, the second transmission component 520 and the image processing component 320 are connected by the second flexible circuit board 540 whose length can be customized, and the installation positions of the second transmission component 520 and the image processing component 320 may not be restricted by the second flexible circuit board 540.

[0097] It should be noted that when the present invention describes a component connected to one end of another component, it roughly limits the positional relationship between the two, that is, closer to one end of the two ends, and does not mean that one component is restricted to being connected to the topmost end of the other component.

[0098] On the basis of the first embodiment, in other embodiments of the present invention, the button assembly 200 can also be disposed on the second section 112 of the first connecting component 110 to further increase the spacing distance from the handle assembly 300 and reduce the probability of false triggering.

The first channel 113 and the second channel 114 are connected to each other. For example, as shown in the figure, the first channel 113 and the second channel 114 are connected through their respective ends. More specifically, the first channel 113 is basically arranged in the vertical direction, and the second channel 114 is basically arranged in the horizontal direction, so that the first channel 113 and the second channel 114 are basically perpendicular.

It should be noted that the "L-shaped structure" referred to in the present invention should be understood as the first connecting component 110 having a turning point to form two sections, and should not be limited to the first section 111 and the second section 112 must be strictly perpendicular.

[0106] On the basis of the second embodiment, in some embodiments of the present invention, the central axis of the first channel 113 and the central axis of the second channel 114 are perpendicular to each other, so as to facilitate the installation of the first optical element 410 and the second optical element 420 with perpendicular optical axes inside.
