It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0061] To address the issue that endoscopes cannot simultaneously achieve automatic zoom and automatic focusing, as well as manual zoom and manual focusing, an endoscope handle is provided according to embodiments of this application. The endoscope handle of this application will be described in detail below with reference to the accompanying drawings.

[0062] See Figures 1 to 6 As shown, according to the first embodiment of the present invention, an endoscope handle is provided, which includes a housing 10, a lens assembly 20, a drive assembly 30, an adjustment assembly 40, and a control unit 50.

[0063] The housing 10 contains a cavity 11. A lens assembly 20 is disposed within the cavity 11, and the lens assembly 20 includes a zoom lens group 21 and a focusing lens group 22 arranged sequentially along the same optical axis 80. Both the zoom lens group 21 and the focusing lens group 22 can reciprocate along the optical axis 80. A drive assembly 30 is disposed within the cavity 11 and connected to the focusing lens group 22 and the zoom lens group 21 to drive at least one of the focusing lens group 22 and the zoom lens group 21 to move along the optical axis 80. An adjustment assembly 40 includes a zoom adjustment section 41 and a focus adjustment section 42, both of which are rotatably disposed within the housing 10. The control unit 50 includes an operation module 51, a control module 52, and a detection module 53. Both the operation module 51 and the detection module 53 are communicatively connected to the control module 52. The operation module 51 is used to transmit control commands to the control module 52. The detection module 53 is used to detect the rotation amount of the zoom adjustment unit 41 and the focus adjustment unit 42 and transmit detection signals to the control module 52. The control module 52 controls the drive assembly 30 according to at least one of the control commands and the detection signals.

[0064] In this application, the operator can manually zoom or focus the endoscope using the adjustment component 40, or automatically zoom or focus the endoscope using the operation module 51. This solves the problem that the endoscope cannot simultaneously perform automatic zooming and automatic focusing, as well as manual zooming and manual focusing. In actual operation, when automatic zooming or focusing of the endoscope is required, the operator can issue the required zoom or focus command to the control module 52 through the operation module 51. The control module 52 then analyzes the received zoom or focus command and transmits the corresponding control command to the drive component 30. Upon receiving the control command, the drive component 30 can perform the movement corresponding to the control command. Since the power output of the drive component 30 is connected to the lens assembly 20, under the drive of the drive component 30, at least one of the zoom lens group 21 and the focusing lens group 22 in the lens assembly 20 can move along the optical axis 80, thereby achieving automatic zooming or automatic focusing of the endoscope. The operation module 51 can take the form of physical buttons or non-physical buttons. Physical buttons include, but are not limited to, toggle switches, buttons, sliders, scroll wheels, knobs, and bridges. Non-physical buttons include, but are not limited to, touchscreens and stereoscopic optical imaging. When manual focusing of the endoscope is required, the operator can rotate the zoom adjustment unit 41. At this time, the detection module 53 can detect the amount of rotation of the zoom adjustment unit 41 and transmit a detection signal to the control module 52. Then, the control module 52 analyzes the received detection signal and transmits a control command to the drive component 30. After receiving the control command, the drive component 30 can drive at least one of the zoom lens group 21 and the focusing lens group 22 to move along the optical axis 80, thereby realizing manual focusing of the endoscope. Furthermore, when manual focusing of the endoscope is required, the operator can rotate the focusing adjustment unit 42. At this time, the detection module 53 can detect the amount of rotation of the focusing adjustment unit 42 and transmit a detection signal to the control module 52. Next, the control module 52 analyzes the received detection signal and transmits a control command to the drive component 30. After receiving the control command, the drive component 30 can drive the focusing lens group 22 to move along the optical axis 80, thereby realizing manual focusing of the endoscope. With the help of manual zoom and manual focusing, the operator can manually adjust the focus of the endoscope.

[0065] In other words, compared with existing endoscope handles, the endoscope handle of this application integrates the functions of automatic zoom and automatic focus as well as manual zoom and manual focus into the endoscope handle through a simple structural design, so that automatic zoom and automatic focus as well as manual zoom and manual focus of the endoscope can be realized simultaneously.

[0066] Further, see Figures 2 to 6As shown, both the zoom adjustment unit 41 and the focus adjustment unit 42 include an adjustment ring 411. The detection module 53 includes a detection element 531, which includes a calculation module (not shown), a first light-emitting unit 5311, and a first light-receiving unit 5312 for receiving light emitted by the first light-emitting unit 5311. The adjustment ring 411 is rotatably mounted on the housing 10 around its own axis, and the adjustment ring 411 has a plurality of adjustment teeth 4111 spaced apart along the circumferential direction of the adjustment ring 411, with equal spacing between adjacent adjustment teeth 4111. The first light-emitting part 5311 and the first light-receiving part 5312 are spaced apart on opposite sides of the adjusting tooth 4111 along the thickness direction of the adjusting tooth 4111. The adjusting tooth 4111 rotates with the adjusting ring 411 to block the light emitted by the first light-emitting part 5311 towards the first light-receiving part 5312. The calculation module is communicatively connected to the first light-receiving part 5312, and the calculation module calculates the rotation amount of the adjusting ring 411 based on the number of times the adjusting tooth 4111 blocks the light and transmits a detection signal to the control module 52.

[0067] Specifically, in the first embodiment of this application (i.e. Figures 1 to 6 As shown in the diagram, the thickness direction of the adjusting tooth 4111 is the radial direction of the adjusting ring 411. In actual operation, the operator rotates the adjusting ring 411 of the zoom adjustment unit 41 around its axial direction. Since the first light-emitting part 5311 and the first light-receiving part 5312 of the detection element 531 are spaced apart on opposite sides of the adjusting tooth 4111 along its thickness direction, the adjusting teeth 4111 on the adjusting ring 411 can intermittently block the light emitted from the first light-emitting part 5311 towards the first light-receiving part 5312 during rotation. During this period, the calculation module can calculate the rotation amount of the adjusting ring 411 based on the number of times the adjusting teeth 4111 block the light, and then transmit the detection signal corresponding to this rotation amount to the control module 52. Next, the control module 52 analyzes the received detection signal, generates corresponding control commands, and transmits them to the drive assembly 30. Upon receiving the control commands, the drive assembly 30 can drive at least one of the zoom lens group 21 and the focusing lens group 22 to move along the optical axis 80, thereby enabling manual zooming of the endoscope. Similarly, when the operator rotates the adjusting ring 411 of the focusing adjustment part 42 around the axial direction of the adjusting ring 411, manual focusing of the endoscope can be achieved, thus enabling manual zooming and manual focusing of the endoscope.

[0068] Exemplarily, in this application, to ensure that the image observed by the endoscope remains clear during automatic and manual focusing, the focusing lens group 22 can be arranged to move along with the zoom lens group 21 during automatic and manual focusing. The first embodiment of this application (i.e....) Figures 1 to 6(as shown) and the second embodiment (i.e. Figure 1 , Figure 3 as well as Figure 7 The diagrams (shown) illustrate the situation where the focusing lens group 22 moves along with the zoom lens group 21. In other embodiments of this application, when the operator performs automatic zooming of the endoscope via the operation module 51 or manual zooming via the zoom adjustment unit 41, the focusing lens group 22 may not move along with the zoom lens group 21. Instead, after automatic zooming, the operator performs automatic focusing via the operation module 51 or manual focusing via the focus adjustment unit 42 to make the image of the endoscope clear.

[0069] Further, see Figures 2 to 6 As shown, the detection element 531 includes at least two, and the at least two detection elements 531 are spaced apart along the circumferential direction of the adjustment ring 411. The control module 52 controls the drive assembly 30 according to the order of light blocking of the at least two detection elements 531 by the adjustment teeth 4111 to drive at least one of the focusing lens group 22 and the zoom lens group 21 to move along the optical axis 80 in the first direction or in the second direction opposite to the first direction.

[0070] Specifically, the first direction is Figure 2 The direction indicated by 'a' is the second direction. Figure 2 The direction indicated by b. In this application, both the zoom adjustment unit 41 and the focus adjustment unit 42 include at least two detection elements 531. The first embodiment of this application (i.e. Figures 1 to 6 (as shown) and the second embodiment (i.e. Figure 1 , Figure 3 as well as Figure 7 The diagrams show that both the zoom adjustment unit 41 and the focus adjustment unit 42 include two detection elements 531. In actual manufacturing of the endoscope handle of this application, the order in which the two detection elements 531 are shielded by the adjustment teeth 4111 can be reasonably adjusted according to actual needs in the direction of movement (first direction and second direction) of at least one of the focusing lens group 22 and the zoom lens group 21 along the optical axis 80. Taking the focus adjustment unit 42 of this application as an example, both the first and second embodiments of this application show a clockwise direction along the adjustment ring 411 (i.e.,...). Figure 5 c and Figure 7The first detection element 531 and the second detection element 531 (in the direction indicated by e) are the first detection element 531a and the second detection element 531b, respectively. When the operator rotates the adjusting ring 411 clockwise, the adjusting teeth 4111 first block the light from the first detection element 531a, and then block the light from the second detection element 531b. At this time, the driving assembly 30 can drive the focusing lens group 22 to move along the first direction or the second direction. Similarly, when the operator rotates counterclockwise (i.e., in the direction indicated by e), the focusing lens group 22 can move along the first direction or the second direction. Figure 5 d and Figure 7 When the adjusting ring 411 is rotated (in the direction indicated by f), the adjusting teeth 4111 first block the light from the second detection element 531b, and then block the light from the first detection element 531a. At this time, the driving assembly 30 can drive the focusing lens group 22 to move along the first direction or the second direction. The first and second embodiments of this application both show the cases where the adjusting ring 411 is rotated clockwise to control the focusing lens group 22 to move along the first direction and the cases where the adjusting ring 411 is rotated counterclockwise to control the focusing lens group 22 to move along the second direction.

[0071] Further, see Figures 4 to 7 As shown, along the circumferential direction of the optical axis 80, two adjacent detection elements 531 are spaced apart by a distance D, and two adjacent adjusting teeth 4111 are spaced apart by a distance P. D and P satisfy the following relationship: Where N is a positive integer.

[0072] Specifically, both the first and second embodiments of this application illustrate the case where N is 1. In the first and second embodiments of this application, when the operator moves in a clockwise direction (i.e., Figure 5 c and Figure 7 When the adjusting ring 411 is rotated (in the direction indicated by e), the adjusting teeth 4111 first block the light from the first detection element 531a, and then... After a certain rotation, the light from the second detection element 531b is blocked by the adjusting tooth 4111. During this period, the calculation module (not shown in the figure) can calculate the rotation of the adjusting ring 411 based on the number of times the adjusting tooth 4111 blocks the light from the detection element 531. Then, the calculation module can transmit the detection signal corresponding to this rotation to the control module 52. After receiving the corresponding detection signal, the control module 52 can analyze the detection signal, and then generate the corresponding control command and transmit it to the drive assembly 30 corresponding to the zoom adjustment unit 41 and the focus adjustment unit 42. After receiving the corresponding control command, the drive assembly 30 can drive the zoom lens group 21 or the focus lens group 22 along the first direction of the optical axis 80 ( Figure 2By moving the endoscope in the direction indicated by 'a', manual focusing or manual zooming of the endoscope can be achieved. Similarly, when the operator moves the endoscope counterclockwise (i.e., ...), the endoscope can be manually zoomed or manually focused. Figure 5 d and Figure 7 When the adjusting ring 411 is rotated in the direction indicated by f, after a process similar to the one described above, the driving assembly 30 can drive the zoom lens group 21 or the focusing lens group 22 along the second direction of the optical axis 80. Figure 2 The endoscope can be moved in the direction indicated by b, thus enabling manual zooming or manual focusing. Furthermore, in this application, D and P satisfy the following relationship: When N is a positive integer, the adjusting ring 411 cannot simultaneously block the light from the first detection element 531a and the second detection element 531b, regardless of whether the adjusting ring 411 rotates clockwise or counterclockwise. This makes it easier for the detection element 531 to count the number of times the adjusting ring 4111 blocks the light, and thus makes it easier to adjust the amount of movement of the zoom lens group 21 and the focusing lens group 22 along the optical axis 80 by the amount of rotation of the adjusting ring 411.

[0073] Further, see Figure 2 As shown, both the zoom adjustment unit 41 and the focus adjustment unit 42 further include an outer ring 412 and an inner ring 413. The inner ring 413 is fixedly connected to the housing 10, the outer ring 412 is sleeved on the outer periphery of the inner ring 413 and can rotate around the axis of the inner ring 413 itself, and the adjustment ring 411 is disposed between the outer ring 412 and the inner ring 413 and is coaxially fixedly connected to the outer ring 412.

[0074] Specifically, in actual operation, the operator can rotate the outer ring 412 of the zoom adjustment unit 41 to drive the adjustment ring 411 of the zoom adjustment unit 41 to rotate around its own axis, thereby causing the adjustment teeth 4111 of the adjustment ring 411 to block the light from the detection element 531 of the zoom adjustment unit 41. During this period, the calculation module (not shown in the figure) can calculate the rotation amount of the adjustment ring 411 of the zoom adjustment unit 41 based on the number of times the adjustment teeth 4111 block the light. Then, the calculation module converts the calculated rotation amount into a detection signal and transmits it to the control module 52. After receiving the detection signal, the control module 52 analyzes it and generates corresponding control commands. Subsequently, the control module 52 transmits the generated control commands to the drive component 30 corresponding to the zoom adjustment unit 41, thereby driving the drive component 30 to work, which in turn drives at least one of the zoom lens group 21 and the focus adjustment unit 42 to move along the optical axis 80. Similarly, by rotating the outer ring 412 of the focusing adjustment unit 42, the operator can drive the focusing lens group 22 to move along the optical axis 80 in the same way as described above. During this period, the zoom lens group 21 does not move with the focusing lens group 22.

[0075] Further, see Figure 1 and Figure 2 As shown, the housing 10 includes a cylindrical shape, with an outer ring 412, an adjusting ring 411, and an inner ring 413 all sleeved on the outer circumferential surface of the cylindrical shape, and the axes of the outer ring 412, the adjusting ring 411, and the inner ring 413 all coincide with the axis of the cylindrical shape.

[0076] Exemplarily, in the first and second embodiments of this application, the housing 10 is configured as a columnar shape. In other embodiments of this application, the housing 10 may also be a cube or cuboid structure. The reason why the housing 10 is configured as a columnar shape in the first and second embodiments of this application is that the columnar design facilitates the installation of the outer ring 412, the adjusting ring 411, and the inner ring 413. If the housing 10 is a cube or cuboid structure, additional installation positions for the outer ring 412, the adjusting ring 411, and the inner ring 413 are required. This would not only make the endoscope handle of this application too large, but also complicate the manufacturing process of the endoscope handle, thereby increasing production costs and hindering the manufacturing of the endoscope handle. Therefore, the columnar design not only makes the endoscope handle more compact and space-saving, but also saves costs to a certain extent. Figure 2 This diagram only shows the zoom adjustment unit 41 mounted on the housing 10. The mounting of the focus adjustment unit 42 can be adjusted during manufacturing according to actual needs. It can be mounted in a similar manner to the zoom adjustment unit 41, either near or far from it.

[0077] Further, see Figure 1 and Figure 2 As shown, the adjusting tooth 4111 protrudes from the inner or outer side of the adjusting ring 411; or, the adjusting tooth 4111 protrudes from the end face of the adjusting ring 411 in the axial direction.

[0078] Exemplarily, the first embodiment of this application (i.e. Figures 1 to 6 As shown, the adjusting tooth 4111 protrudes from the end face of the adjusting ring 411 in the axial direction, and the adjusting tooth 4111 is along the first direction of the optical axis 80. Figure 2 The direction indicated by 'a' in the middle extends as described in the second direction of the optical axis 80. In other embodiments of this application, the adjusting tooth 4111 may also extend along the second direction of the optical axis 80. Figure 2(as indicated by b) extends. When the adjusting tooth 4111 protrudes from the end face of the adjusting ring 411 in the axial direction and extends along the optical axis 80, the radial dimension of the endoscope handle can be reduced to a certain extent, saving space. Furthermore, compared to the method where the adjusting tooth 4111 protrudes from the inner or outer side of the adjusting ring 411, the method where the adjusting tooth 4111 protrudes from the end face of the adjusting ring 411 in the axial direction and extends along the optical axis 80 has a simpler manufacturing process and can save production costs to a certain extent. Therefore, in general, this application typically adopts the method where the adjusting tooth 4111 protrudes from the end face of the adjusting ring 411 in the axial direction and extends along the optical axis 80. The second embodiment of this application (i.e....) Figure 1 , Figure 3 as well as Figure 7 The diagram shows an adjusting tooth 4111 protruding from the inner side of the adjusting ring 411 and extending along the center of the adjusting ring 411. In other embodiments of this application, the adjusting tooth 4111 may also protrude from the inner side of the adjusting ring 411, and the extension direction of the adjusting tooth 4111 may be reasonably adjusted according to actual needs. The adjusting tooth 4111 may also protrude from the outer side of the adjusting ring 411, and the extension direction of the adjusting tooth 4111 may also be reasonably adjusted according to actual needs. This application does not impose specific limitations on the specific structure of the adjusting ring 411 and the adjusting tooth 4111. Any reasonable adjustments made based on actual needs on the basis of this application are within the scope of protection claimed in this application.

[0079] Further, see Figure 2 and Figure 3 As shown, the drive assembly 30 includes a first drive device 31 and a second drive device 32. One of the first drive device 31 and the second drive device 32 is connected to the focusing lens group 22 to drive the focusing lens group 22 to move along the optical axis 80, and the other of the first drive device 31 and the second drive device 32 is connected to the zoom lens group 21 to drive the zoom lens group 21 to move along the optical axis 80.

[0080] Specifically, in this application, a first driving device 31 can be used to drive the zoom lens group 21 and a second driving device 32 can be used to drive the focusing lens group 22, or vice versa. The first and second embodiments of this application both show the case where the first driving device 31 drives the zoom lens group 21 and the second driving device 32 drives the focusing lens group 22. In actual operation, the operator can control the first driving device 31 to move the zoom lens group 21 along the optical axis 80 by rotating the outer ring 412 of the zoom adjustment unit 41. If the focusing lens group 22 is linked to the zoom lens group 21, the operator can control the first driving device 31 to move the zoom lens group 21 along the optical axis 80 and control the second driving device 32 to move the focusing lens group 22 along the optical axis 80 by rotating the outer ring 412 of the zoom adjustment unit 41, thereby achieving manual zooming of the endoscope. Furthermore, the operator can control the second drive device 32 to drive the zoom lens group 21 to move along the optical axis 80 by rotating the outer ring 412 of the focusing adjustment unit 42, thereby achieving manual focusing of the endoscope. In addition, the first drive device 31 and the second drive device 32 of this application can be motors, and both the first and second embodiments of this application show that the first drive device 31 and the second drive device 32 are linear motors. The use of a linear motor can reduce the radial dimension of the endoscope handle to a certain extent, saving space. It can also reduce the need for an intermediate mechanism to transmit the motor's power to the zoom lens group 21 and the focusing lens group 22, thus reducing energy loss in the first drive device 31 and the second drive device 32, and consequently saving costs to a certain extent.

[0081] Further, see Figure 2 and Figure 3 As shown, the endoscope handle also includes an imaging element 60 and an image processing unit 70. Both the imaging element 60 and the image processing unit 70 are disposed in the cavity 11. The imaging element 60 is located on the image side of the lens assembly 20, and both the image processing unit 70 and the imaging element 60 are communicatively connected to the control module 52.

[0082] Specifically, in actual operation, the imaging element 60 converts the light transmitted from the focusing lens group 22 and the zoom lens group 21 into image signals and transmits them to the image processing unit 70. The image processing unit 70 then processes the received image signals and transmits them to the control module 52. The control module 52 then processes the received image signals and transmits them to a display screen (not shown) or other display device (not shown) for display, thus allowing the image observed by the endoscope to be presented in the operator's field of vision. Furthermore, when the imaging element 60 receives light transmitted from the focusing lens group 22 and the zoom lens group 21, the imaging element 60 can transmit a signal to the image processing unit 70. The image processing unit 70 then processes the received signal and transmits it to the control module 52, which in turn processes the received image signal. When the control module 52 detects that the white balance and other parameters of the image returned by the image processing unit 70 do not meet the requirements, the control module 52 can issue a corresponding control command to the image processing unit 70. Then, the image processing unit 70 processes the control command issued by the control module 52 and transmits it to the imaging element 60. The imaging element 60 adjusts the white balance and other parameters according to the received control command, so that the white balance and other parameters of the image observed by the endoscope meet the requirements, thus facilitating the operator's observation.

[0083] Furthermore, this application also mentions an endoscope including the aforementioned endoscope handle. Specifically, by installing the endoscope handle of this application into the endoscope, the endoscope can simultaneously perform automatic zooming and autofocusing as well as manual zooming and manual focusing operations, thereby making the image observed by the endoscope clearer. Simultaneously, when the operator uses the endoscope equipped with the endoscope handle of this application, automatic zooming and autofocusing as well as manual zooming and manual focusing operations can be performed through the operation module 51, zoom adjustment unit 41, and focus adjustment unit 42 on the endoscope handle, helping the operator quickly locate the area to be observed and clearly present the image of the area to be observed in the operator's field of vision.

[0084] See Figures 1 to 3 , Figure 8 As shown, according to the third embodiment of the present invention, another endoscope handle is provided. For ease of distinction, the endoscope handle mentioned in the third embodiment will be referred to as the second type of endoscope handle below. The second type of endoscope handle includes a housing 10, a lens assembly 20, and an adjustment assembly 40.

[0085] The housing 10 contains a cavity 11. A lens assembly 20 is disposed within the cavity 11, and the lens assembly 20 includes a zoom lens group 21 and / or a focusing lens group 22 arranged sequentially along the same optical axis 80. Both the zoom lens group 21 and / or the focusing lens group 22 can reciprocate along the optical axis 80. An adjustment assembly 40 includes a zoom adjustment section 41 and / or a focusing adjustment section 42, both of which are rotatably disposed within the housing 10, for adjusting the reciprocating movement of the lens assembly 20 along the optical axis 80.

[0086] With the second type of endoscope handle, the operator can manually zoom or focus the endoscope using the adjustment assembly 40. In actual operation, when manual zooming is required, the operator can rotate the zoom adjustment unit 41 relative to the housing 10, thereby adjusting at least one of the zoom lens group 21 and the focusing lens group 22 to reciprocate along the optical axis 80, thus achieving manual zooming of the endoscope. Furthermore, when manual focusing is required, the operator can rotate the focusing adjustment unit 42 relative to the housing 10, thereby driving the focusing lens group 22 to reciprocate along the optical axis 80, thus achieving manual focusing of the endoscope. Through manual zooming and manual focusing, the operator can manually adjust the focus of the endoscope.

[0087] Furthermore, to ensure that the image observed by the endoscope remains clear during manual zooming, the focusing lens group 22 can be configured to move along with the zoom lens group 21, thereby guaranteeing that the image observed by the endoscope remains clear. Alternatively, the zoom adjustment unit 41 can independently adjust the reciprocating movement of the zoom lens group 21 along the optical axis 80, and the focusing adjustment unit 42 can independently adjust the reciprocating movement of the focusing lens group 22 along the optical axis 80.

[0088] Further, see Figure 2 and Figure 3 As shown, the second type of endoscope handle also includes a drive assembly 30 and a control unit 50. The drive assembly 30 is disposed in the cavity 11 and connected to the focusing lens group 22 and the zoom lens group 21 to drive at least one of the focusing lens group 22 and the zoom lens group 21 to move along the optical axis 80. The control unit 50 includes an operation module 51, a control module 52, and a detection module 53. Both the operation module 51 and the detection module 53 are communicatively connected to the control module 52. The operation module 51 transmits control commands to the control module 52, and the detection module 53 detects the rotation amount of the zoom adjustment unit 41 and the focusing adjustment unit 42 and transmits detection signals to the control module 52. The control module 52 controls the drive assembly 30 according to at least one of the control commands and the detection signals.

[0089] Specifically, when using the second type of endoscope handle, the operator can manually zoom or focus the endoscope using the adjustment component 40, or automatically zoom or focus the endoscope using the operation module 51. This solves the problem that the endoscope cannot simultaneously perform automatic zooming and automatic focusing, or manual zooming and manual focusing. In actual operation, when automatic zooming or focusing of the endoscope is required, the operator can issue the required zoom or focus command to the control module 52 through the operation module 51. The control module 52 then analyzes the received zoom or focus command and transmits the corresponding control command to the drive component 30. After receiving the control command, the drive component 30 can perform the movement corresponding to the control command. The power output end of the drive component 30 is connected to the lens assembly 20. Therefore, under the drive of the drive component 30, at least one of the zoom lens group 21 and the focusing lens group 22 in the lens assembly 20 can move along the optical axis 80, thereby realizing the automatic zooming or automatic focusing of the endoscope. The operation module 51 can take the form of physical buttons or non-physical buttons. Physical buttons include, but are not limited to, toggle switches, buttons, sliders, scroll wheels, knobs, and bridges. Non-physical buttons include, but are not limited to, touchscreens and stereoscopic optical imaging. When manual focusing of the endoscope is required, the operator can rotate the zoom adjustment unit 41. At this time, the detection module 53 can detect the amount of rotation of the zoom adjustment unit 41 and transmit a detection signal to the control module 52. Then, the control module 52 analyzes the received detection signal and transmits a control command to the drive component 30. After receiving the control command, the drive component 30 can drive at least one of the zoom lens group 21 and the focusing lens group 22 to move along the optical axis 80, thereby realizing manual focusing of the endoscope. Furthermore, when manual focusing of the endoscope is required, the operator can rotate the focusing adjustment unit 42. At this time, the detection module 53 can detect the amount of rotation of the focusing adjustment unit 42 and transmit a detection signal to the control module 52. Next, the control module 52 analyzes the received detection signal and transmits a control command to the drive component 30. After receiving the control command, the drive component 30 can drive the focusing lens group 22 to move along the optical axis 80, thereby realizing manual focusing of the endoscope. With the help of manual zoom and manual focusing, the operator can manually adjust the focus of the endoscope.

[0090] In other words, compared with existing endoscope handles, the second endoscope handle of this application integrates the functions of automatic zoom and automatic focus as well as manual zoom and manual focus into the endoscope handle through a simple structural design, so that automatic zoom and automatic focus as well as manual zoom and manual focus of the endoscope can be realized simultaneously.

[0091] Further, see Figure 2 , Figure 3as well as Figure 8 As shown, the adjustment assembly 40 includes an adjustment ring 411, and the adjustment ring 411 is provided with a plurality of adjustment teeth 4111 spaced apart along the circumferential direction of the adjustment ring 411. The adjustment ring 411 is rotatably disposed on the housing 10 around its own axis, and the axis 4112 and / or the outer periphery of the adjustment ring 411 are provided with a rotation detection structure 532 for detecting the rotation angle and / or step length of the adjustment ring.

[0092] For example, in the second type of endoscope handle, a rotation detection structure 532 can be provided at the axis of the adjusting ring 411, or a rotation detection structure 532 can be provided on the outer periphery of the adjusting ring 411. The third embodiment of this application (e.g.) Figures 1 to 3 , Figure 8 The diagram shows a case where a rotation detection structure 532 is arranged at the axis of the adjusting ring 411. This rotation detection structure 532 can be, for example, a tilt sensor, a laser detection device, or an optical encoder. In actual use of the endoscope handle, the operator rotates clockwise relative to the housing 10 (i.e.,...). Figure 8 (in the direction indicated by g) or counterclockwise (i.e.) Figure 8 When the adjustment ring 411 rotates around its own axis (in the direction indicated by h), the rotation detection structure located at the axis 4112 can detect the rotation angle and / or step size of the adjustment ring 411, and then adjust at least one of the zoom lens group 21 and the focusing lens group 22 to move along the optical axis 80.

[0093] Further, see Figures 1 to 3 , Figure 5 as well as Figure 8 As shown, the control unit 50 of the second type of endoscope handle also includes a first light-emitting part 5311 and a first light-receiving part 5312. The first light-emitting part 5311 and the first light-receiving part 5312 are spaced apart on opposite sides of the adjusting tooth 4111 along the thickness direction of the adjusting tooth 4111. The adjusting tooth 4111 rotates with the adjusting ring 411 to block the light emitted by the first light-emitting part 5311 towards the first light-receiving part 5312.

[0094] Specifically, during actual operation, the operator rotates the adjustment ring 411 of the zoom adjustment unit 41 around the axial direction of the adjustment ring 411. Since the first light-emitting part 5311 and the first light-receiving part 5312 of the control unit 50 are spaced apart on opposite sides of the adjustment teeth 4111 along the thickness direction of the adjustment teeth 4111, the adjustment teeth 4111 on the adjustment ring 411 can intermittently block the light emitted by the first light-emitting part 5311 towards the first light-receiving part 5312 during the rotation of the adjustment ring 411. During this period, by detecting the rotation angle and / or step size of the adjustment ring by the rotation detection structure 532, at least one of the zoom lens group 21 and the focusing lens group 22 can be adjusted to reciprocate along the optical axis 80, thereby realizing manual zooming of the endoscope. Similarly, when the operator rotates the adjustment ring 411 of the focusing adjustment unit 42 around the axial direction of the adjustment ring 411, the focusing lens group 22 can be adjusted to reciprocate along the optical axis 80, thereby realizing manual focusing of the endoscope.

[0095] Exemplarily, in this application, to ensure that the image observed by the endoscope remains clear during automatic and manual focusing, the focusing lens group 22 can be arranged to move along with the zoom lens group 21 during automatic and manual focusing. The first embodiment of this application (i.e....) Figures 1 to 6 As shown), the second embodiment (i.e. Figure 1 , Figure 3 as well as Figure 7 (as shown) and the third embodiment (as shown) Figures 1 to 3 , Figure 8 The diagrams (shown) illustrate the situation where the focusing lens group 22 moves along with the zoom lens group 21. In other embodiments of this application, when the operator performs automatic zooming of the endoscope via the operation module 51 or manual zooming via the zoom adjustment unit 41, the focusing lens group 22 may not move along with the zoom lens group 21. Instead, after automatic zooming, the operator performs automatic focusing via the operation module 51 or manual focusing via the focus adjustment unit 42 to make the image of the endoscope clear.

[0096] See Figures 1 to 3 , Figure 5 As shown, according to the fourth embodiment of the present invention, another endoscope handle is provided. For ease of distinction, the endoscope handle mentioned in the fourth embodiment will be referred to as the third endoscope handle below. The third endoscope handle includes a housing 10, a lens assembly 20, an adjustment assembly 40, and a control unit 50.

[0097] The housing 10 contains a cavity 11. A lens assembly 20 is disposed within the cavity 11 and includes a zoom lens group 21 and a focusing lens group 22 arranged sequentially along the same optical axis 80. Both the zoom lens group 21 and the focusing lens group 22 can reciprocate along the optical axis 80. An adjustment assembly 40 includes a zoom adjustment section 41 and a focus adjustment section 42, both rotatably disposed within the housing 10. A control unit 50 includes an operation module 51, a control module 52, and a detection module 53. Both the operation module 51 and the detection module 53 are communicatively connected to the control module 52. The operation module 51 transmits control commands to the control module 52, and the detection module 53 detects the rotation amount of the zoom adjustment section 41 and the focus adjustment section 42 and transmits a detection signal to the control module 52. The control module 52 controls the lens assembly 20 based on at least one of the control commands and the detection signal.

[0098] In the third type of endoscope handle of this application, the operator can manually zoom or focus the endoscope via the adjustment component 40, or automatically zoom or focus the endoscope via the operation module 51. This solves the problem that the endoscope cannot simultaneously achieve automatic zooming and automatic focusing, as well as manual zooming and manual focusing. In actual operation, when automatic zooming or automatic focusing of the endoscope is required, the operator can issue the required zoom or focus command to the control module 52 via the operation module 51. Then, the control module 52 analyzes the received zoom or focus command and controls at least one of the zoom lens group 21 and the focus lens group 22 in the lens assembly 20 to reciprocate along the optical axis 80, thereby realizing automatic zooming or automatic focusing of the endoscope. The operation module 51 can take the form of physical buttons or non-physical buttons. Physical buttons include, but are not limited to, toggle switches, buttons, sliders, scroll wheels, knobs, and bridge-type switches. Non-physical buttons include, but are not limited to, touchscreens and stereoscopic optical imaging. When manual focusing of the endoscope is required, the operator can rotate the zoom adjustment unit 41. At this time, the detection module 53 can detect the amount of rotation of the zoom adjustment unit 41 and transmit a detection signal to the control module 52. Then, the control module 52 analyzes the received detection signal and controls at least one of the zoom lens group 21 and the focusing lens group 22 in the lens assembly 20 to reciprocate along the optical axis 80, thereby realizing manual focusing of the endoscope. Furthermore, when manual focusing of the endoscope is required, the operator can rotate the focusing adjustment unit 42. At this time, the detection module 53 can detect the amount of rotation of the focusing adjustment unit 42 and transmit a detection signal to the control module 52. Then, the control module 52 analyzes the received detection signal and controls the focusing lens group 22 to reciprocate along the optical axis 80, thereby realizing manual focusing of the endoscope. With manual zoom and manual focus, operators can manually adjust the focus of the endoscope.

[0099] In other words, compared with existing endoscope handles, the third type of endoscope handle in this application integrates the functions of automatic zoom and automatic focus as well as manual zoom and manual focus into the endoscope handle through a simple structural design, so that automatic zoom and automatic focus as well as manual zoom and manual focus of the endoscope can be realized simultaneously.

[0100] Furthermore, to ensure that the image observed by the endoscope remains clear during manual zooming, the focusing lens group 22 can be configured to move along with the zoom lens group 21, thereby guaranteeing that the image observed by the endoscope remains clear. Alternatively, the zoom adjustment unit 41 can independently adjust the reciprocating movement of the zoom lens group 21 along the optical axis 80, and the focusing adjustment unit 42 can independently adjust the reciprocating movement of the focusing lens group 22 along the optical axis 80.

[0101] Further, see Figure 2 and Figure 3 As shown, the endoscope handle also includes a drive assembly 30, which is disposed in the cavity 11 and connected to the focusing lens group 22 and the zoom lens group 21 to drive at least one of the focusing lens group 22 and the zoom lens group 21 to move along the optical axis 80. Furthermore, the drive assembly 30 includes a first drive device 31 and a second drive device 32. One of the first drive device 31 and the second drive device 32 is connected to the focusing lens group 22 to drive the focusing lens group 22 to move along the optical axis 80, and the other of the first drive device 31 and the second drive device 32 is connected to the zoom lens group 21 to drive the zoom lens group 21 to move along the optical axis 80.

[0102] Specifically, in the third type of endoscope handle of this application, a first driving device 31 can be used to drive the zoom lens group 21 and a second driving device 32 can be used to drive the focusing lens group 22, or vice versa. The first, second, third, and fourth embodiments of this application all show the case where the first driving device 31 drives the zoom lens group 21 and the second driving device 32 drives the focusing lens group 22. In actual use of the third type of endoscope handle, the operator can control the first driving device 31 to move the zoom lens group 21 along the optical axis 80 by rotating the outer ring 412 of the zoom adjustment part 41. If the focusing lens group 22 is linked with the zoom lens group 21, the operator can control the first driving device 31 to move the zoom lens group 21 along the optical axis 80 and control the second driving device 32 to move the focusing lens group 22 along the optical axis 80 by rotating the outer ring 412 of the zoom adjustment part 41, thereby realizing manual zooming of the endoscope. Furthermore, the operator can control the second drive device 32 to drive the zoom lens group 21 to move along the optical axis 80 by rotating the outer ring 412 of the focusing adjustment unit 42, thereby achieving manual focusing of the endoscope. In addition, the first drive device 31 and the second drive device 32 of this application can be motors, and the first, second, and third embodiments of this application all show the case where both the first drive device 31 and the second drive device 32 are linear motors. The use of a linear motor can reduce the radial dimension of the endoscope handle to a certain extent, saving space. It can also reduce the need for an intermediate mechanism to transmit the motor's power to the zoom lens group 21 and the focusing lens group 22, thus reducing energy loss in the first drive device 31 and the second drive device 32, and consequently saving costs to a certain extent.

[0103] Further, see Figure 2 , Figures 4 to 8 As shown, the adjustment assembly 40 includes an adjustment ring 411, and the housing 10 includes a cylindrical shape. The adjustment ring 411 is rotatably disposed on the housing 10 about its own axis, and the adjustment ring 411 is provided with a plurality of adjustment teeth 4111 spaced apart along the circumferential direction of the adjustment ring 411, with equal spacing between two adjacent adjustment teeth 4111. Both the zoom adjustment part 41 and the focus adjustment part 42 also include an outer ring 412 and an inner ring 413. The inner ring 413 is fixedly connected to the housing 10, the outer ring 412 is sleeved on the outer circumference of the inner ring 413 and can rotate about the axis of the inner ring 413, and the adjustment ring 411 is disposed between the outer ring 412 and the inner ring 413 and is coaxially fixedly connected to the outer ring 412; the outer ring 412, the adjustment ring 411 and the inner ring 413 are all sleeved on the outer circumferential surface of the cylindrical shape, and the axes of the outer ring 412, the adjustment ring 411 and the inner ring 413 are all coincident with the axis of the cylindrical shape.

[0104] Specifically, the third type of endoscope handle has the same arrangement of the adjusting teeth 4111 on the adjusting ring 411 as shown in the second embodiment. In actual operation, the operator rotates the outer ring 412 of the zoom adjustment unit 41, which in turn rotates the adjusting ring 411 around its own axis. This causes the adjusting teeth 4111 to block the light from the detection element 531 of the zoom adjustment unit 41. During this time, the calculation module (not shown in the figure) calculates the rotation amount of the adjusting ring 411 of the zoom adjustment unit 41 based on the number of times the adjusting teeth 4111 block the light. The calculation module then converts the calculated rotation amount into a detection signal and transmits it to the control module 52. After receiving the detection signal, the control module 52 analyzes it and generates corresponding control commands. The control module 52 then transmits the generated control commands to the drive assembly 30 corresponding to the zoom adjustment unit 41, thereby driving the drive assembly 30 to operate. This allows at least one of the zoom lens group 21 and the focus adjustment unit 42 to reciprocate along the optical axis 80. Similarly, by rotating the outer ring 412 of the focus adjustment unit 42, the operator can drive the focus lens group 22 to reciprocate along the optical axis 80 in the same manner as described above. During this process, the zoom lens group 21 does not move with the focus lens group 22.

[0105] Exemplarily, in the first, second, third, and fourth embodiments of this application, the housing 10 is configured as a columnar shape. In other embodiments of this application, the housing 10 may also be a cube or cuboid structure. The reason why the housing 10 is configured as a columnar shape in the first, second, third, and fourth embodiments of this application is that the columnar design facilitates the installation of the outer ring 412, the adjusting ring 411, and the inner ring 413. If the housing 10 is a cube or cuboid structure, additional installation positions for the outer ring 412, the adjusting ring 411, and the inner ring 413 are required. This would not only make the endoscope handle of this application too large, but also complicate the manufacturing process of the endoscope handle, thereby increasing production costs and hindering the manufacturing of the endoscope handle. Therefore, the columnar design not only makes the endoscope handle more compact and space-saving, but also saves costs to a certain extent. Figure 2 This diagram only shows the zoom adjustment unit 41 mounted on the housing 10. The mounting of the focus adjustment unit 42 can be adjusted during manufacturing according to actual needs. It can be mounted in a similar manner to the zoom adjustment unit 41, either near or far from it.

[0106] As can be seen from the above description, this application solves the problem that endoscopes cannot simultaneously achieve automatic zoom and automatic focus, as well as manual zoom and manual focus, by setting up an endoscope handle composed of a housing 10, a lens assembly 20, a drive assembly 30, an adjustment assembly 40, a control unit 50, an imaging element 60, and an image processing unit 70. In actual use, the operator can realize the automatic zoom and automatic focus functions of the endoscope through the operation module 51 integrated on the endoscope handle housing 10. When the operator performs automatic zoom and automatic focus tasks through the operation module 51, the control module 52 receives the control command from the operation module 51, thereby controlling the first drive device 31 and the second drive device 32 to drive the zoom lens group 21 and the focusing lens group 22 to move along the optical axis 80 to the target position. During the movement of the zoom lens group 21, the focusing lens group 22 can follow the movement of the zoom lens group 21, thereby ensuring that the image remains clear throughout the zooming process. When the operator deems the image clarity obtained from autofocus and autofocus insufficient, or believes the image does not represent the desired location, the operator can control the first drive device 31 and the second drive device 32 to move at least one of the zoom lens group 21 and the focusing lens group 22 along the optical axis 80 to the target position by rotating the outer ring 412 of the zoom adjustment unit 41 and the focusing adjustment unit 42. To ensure the endoscope image remains clear during manual focusing, when the operator rotates the zoom adjustment unit 41 for manual focusing, the focusing lens group 22 moves along the optical axis 80 along with the zoom lens group 21. This allows the endoscope to observe the desired location and maintain a clear image at that location.

[0107] As can be seen, the endoscope handle of this application can realize the functions of automatic and manual focusing of the endoscope through a simple structural design, and has the advantages of convenient operation and low cost.

[0108] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0109] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0110] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
