[0001] This invention relates to the field of imaging equipment technology, and in particular to a gross specimen imaging device and its control method. Background Technology

[0002] The gross specimen imaging system, also known as the gross specimen imaging system, is mainly used to collect images and video information of the sampling process of pathological specimens on the pathology sampling table.

[0003] Existing gross specimen imaging devices can be found in Chinese invention patent application CN109996000A, which discloses a gross specimen imaging system for projecting image information. The system includes an imaging device, a specimen platform, and a universal support. The imaging device comprises an industrial computer, a camera, and a projector. The industrial computer is electrically connected to the camera and the projector. The camera is used to acquire specimen images, and the projector is used to project image information. The specimen platform includes a base plate, a right light source, and a left light source. The base plate is used to place the gross specimen; the right and left light sources provide illumination. The universal support includes an articulated arm, a vertical column, and a base plate clamp. The articulated arm connects the vertical column and the imaging device; the vertical column connects the articulated arm and the base plate clamp, used to adjust the position of the imaging device and retract cables; the base plate clamp connects the vertical column and the base plate, used to fix the position of the universal support on the specimen platform.

[0004] Existing gross specimen imaging devices connect the camera to a projector or PC, which then displays the collected images. However, when staff are taking samples, they need to manually adjust the camera, which interferes with the sampling process and is inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a macroscopic specimen imaging device that allows for convenient viewing and control of the acquired image information during sampling operations.

[0006] The above-mentioned objective of this invention is achieved through the following technical solution: a gross specimen imaging device, comprising an instrument housing, a camera being disposed on the lower surface of the instrument housing, an MCU and a storage chip being disposed inside the instrument housing, and a display screen being disposed on one side surface of the instrument housing; further comprising a foot pedal controller, the foot pedal controller comprising a plurality of foot switches and a wireless signal transmitter, the MCU being connected to a wireless signal receiver; the foot switches being used to convert foot pedal signals into analog signals; the wireless signal transmitter being used to send the analog signals output by the foot switches to the wireless signal receiver.

[0007] By adopting the above technical solution, the instrument housing is fixed above the case sampling station, the acquisition camera is set downwards, and the display screen faces the operation side. Thus, during the sampling operation, the staff can watch the sampling operation in real time through the display screen. When it is necessary to adjust the display screen, the corresponding operation can be performed by pressing the foot pedal switch with the foot, without affecting the staff's hand sampling operation, making the operation convenient and quick.

[0008] The present invention is further configured such that: a plurality of foot switches are distributed around the center of a virtual circle O, and the length direction of the foot switches is arranged radially along the virtual circle O.

[0009] By adopting the above technical solution, several foot switches are distributed around the center of the virtual circle O, and the length direction of the foot switches is set along the radial direction of the virtual circle O. Thus, when using the foot controller, it is convenient for the operator to operate each foot switch of the foot controller with the operating foot as the center. The range of foot movement is small and the operation is convenient.

[0010] The present invention is further configured such that: the foot switch includes a positive focus switch, a negative focus switch, and a photo capture switch; the positive focus switch is used to input a focal length increase signal from the acquisition camera, and the negative focus switch is used to input a focal length decrease signal from the acquisition camera; the photo capture switch is used to input a photo capture trigger signal from the acquisition camera; the photo capture switch is located between the positive focus switch and the negative focus switch.

[0011] By adopting the above technical solution, the foot switch includes a positive focus switch, a negative focus switch, and a camera switch, which facilitates the operator to perform focusing and photography operations through the foot controller. Furthermore, by placing the camera switch between the positive and negative focus switches, it prevents the operator from accidentally using the positive and negative focus switches when adjusting the focus.

[0012] The present invention is further configured such that: the upper surface of the foot switch is provided with a plurality of strip-shaped protrusions along the width direction of the foot switch.

[0013] By adopting the above technical solution, multiple strip-shaped protrusions along the width direction of the foot switch are provided on the upper surface of the foot switch, thereby increasing the contact friction between the worker's foot and the foot switch when performing foot operation, so that the worker's foot is less likely to slip when performing foot operation.

[0014] The present invention is further configured such that: the MCU is connected to an I / O port, and the I / O port is used to connect to a peripheral device for data transmission.

[0015] By adopting the above technical solution, the MCU is connected to an I / O port, which allows the collected video information to be synchronously transmitted to other devices when staff perform sampling operations, facilitating collaborative work among staff.

[0016] The present invention is further configured such that the I / O ports include a VGA port, a USB port, a miniUSB port, an HDMI port, an RS-232 port, and a Compositevideo port.

[0017] By adopting the above technical solutions, the I / O ports include various types such as VGA ports, USB ports, miniUSB ports, HDMI ports, RS-232 ports, and Compositevideo ports. This allows staff to select different I / O ports according to their actual usage needs, meeting the needs of various occasions.

[0018] Another objective of this invention is to provide a control method for a gross specimen imaging device, which allows for convenient viewing and control adjustment of the acquired image information during sampling operations.

[0019] The above-mentioned objective of this invention is achieved through the following technical solution: a control method for a gross specimen imaging device, which uses the above-mentioned gross specimen imaging device, wherein the MCU judges the foot pedal time information based on the analog signal output by the foot switch, and linearly adjusts the focal length of the acquisition camera based on the foot pedal time information.

[0020] By adopting the above technical solution, the MCU judges the foot pedal time information based on the analog signal output by the foot switch, and then linearly adjusts the focal length of the acquisition camera based on the foot pedal time information. Thus, the MCU can accurately adjust the focal length of the acquisition camera according to the input instructions of the staff, and it is easy for the staff to operate and control.

[0021] The present invention is further configured such that: the MCU is connected to a speed adjustment module, the speed adjustment module is used to input a rate adjustment command, and the MCU adjusts the zoom rate of the acquisition camera according to the rate adjustment command.

[0022] By adopting the above technical solution, the zoom rate of the acquisition camera can be changed by inputting a speed adjustment command through the speed control module, thereby making it more accurate and convenient for the operator to zoom the acquisition camera.

[0023] The present invention is further configured such that: the MCU pre-generates image information for the next time node based on the current image information captured by the acquisition camera, and sends the pre-generated image information to the display screen, and the display screen displays the pre-generated image information.

[0024] By adopting the above technical solution, when zooming the acquisition camera via a foot switch, there will be a certain degree of delay between the actual input of the operator and the real-time display on the screen. The MCU pre-generates the image information for the next time node based on the current image information acquired by the acquisition camera, so that the operator can more accurately control the focal length of the acquisition camera when zooming.

[0025] In summary, the beneficial technical effects of the present invention are as follows:

[0026] 1. Fix the instrument housing above the case sampling station, with the acquisition camera facing downwards and the display screen facing the operating side. This allows staff to view the sampling operation in real time through the display screen. When it is necessary to adjust the display screen, the corresponding operation can be performed by pressing the foot pedal switch. This does not affect the staff's hand sampling operation, making the operation convenient and quick.

[0027] 2. The foot switches are arranged in a ring, including a positive focus switch, a negative focus switch, and a camera switch. This makes it convenient for staff to perform focusing and photography operations through the foot controller. Furthermore, by placing the camera switch between the positive and negative focus switches, staff are less likely to mix up the positive and negative focus switches when adjusting the focus.

[0028] 3. The MCU adjusts the zoom rate of the camera when the foot switch is pressed by the speed control module through the speed adjustment command input. In addition, the MCU pre-generates the image information of the next time node based on the current image information captured by the camera, so that the operator can more accurately control the focal length of the camera when zooming.

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] Example 1:

[0039] A macroscopic specimen imaging device, referring to Figure 1 and Figure 2 The system includes an instrument housing 1 and a mounting assembly 3 for mounting and securing the instrument housing 1. A camera 11 is mounted on the lower surface of the instrument housing 1. An MCU 12 and a storage chip 13 are housed inside the instrument housing 1. A display screen 14 is mounted on one side of the instrument housing 1. When using the gross specimen imaging device, the instrument housing 1 is mounted above the sampled specimen using the mounting assembly 3. The camera 11 faces the sampled specimen, and the display screen 14 faces the operating side of the pathology sampling table. The MCU 12 is connected to an I / O port 15, which is used to connect to peripherals for data transmission. The MCU 12 sends the acquired video information to external devices in real time through the I / O port 15, allowing the external devices to synchronously display the video information acquired by the camera 11. Furthermore, the system can be connected to a PC via the I / O port 15 for debugging and control of the gross specimen imaging device. The I / O port 15 includes a VGA port, a USB port, a miniUSB port, an HDMI port, an RS-232 port, and a CompositeVideo port, providing a variety of interfaces to meet the needs of various applications. The MCU12 stores the images and video information captured by the camera 11 into the storage chip 13, so that the captured images and videos can be retrieved and viewed later.

[0040] Reference Figure 1 and Figure 3 The mounting assembly 3 includes a mounting base 31, a vertical slide rail 32, and a horizontal slide rail 33. The pathological sampling table includes a table body 41 and a mounting bracket 42 fixed to the table body 41. When installing the instrument housing 1, the horizontal slide rail 33 is horizontally fixed to the mounting bracket 42. Multiple stepped holes 331 penetrating the horizontal slide rail 33 are provided on the surface of the horizontal slide rail 33 near the vertical slide rail 32, and these stepped holes 331 are distributed along the length of the horizontal slide rail 33. The horizontal slide rail 33 is fixed to the mounting bracket 42 by bolts inserted into the stepped holes 331 through threaded holes in the mounting bracket 42.

[0041] Reference Figure 3 and Figure 4 The mounting base 31 includes a mounting plate 311 and a connecting arm 312 that is perpendicularly disposed and fixedly connected to the surface of the mounting plate 311. An adjusting arm 18 is fixed to the surface of the instrument housing 1 away from the display screen 14, and the adjusting arm 18 is hinged to the connecting arm 312 around a vertical axis. By rotating the instrument housing 1 around the hinge axis of the adjusting arm 18 and the connecting arm 312, the acquisition position of the acquisition camera 11 can be easily and quickly adjusted.

[0042] Refer to 3 and Figure 5 A vertical slide rail 32 is vertically mounted on a horizontal slide rail 33. A mounting plate 311 can be placed in the vertical slide rail 32 and is slidably connected to the vertical slide rail 32 along its length. A height scale 321 is provided on one side of the vertical slide rail 32, extending along its length. A threaded knob 35 is provided on one side of the vertical slide rail 32. The threaded knob 35 includes a screw 351 and an operating handle 352 fixed to one end of the screw 351. A plurality of threaded holes 322 penetrating the side wall of the vertical slide rail 32 are provided on one side of the vertical slide rail 32. These threaded holes 322 are arranged along the length of the vertical slide rail 32, and the screw 351 engages with the threaded holes 322. By sliding the mounting base 31 along the length of the vertical slide rail 32, the height of the instrument housing 1 can be adjusted. The threaded knob 35 is installed in the corresponding threaded hole 322. By rotating the threaded knob 35, the end face of the screw 351 abuts against the side of the mounting plate 311, thereby fixing the mounting base 31 and the vertical slide rail 32 relative to each other.

[0043] A sliding connector 34 is fixed to the surface of the vertical slide rail 32 near the horizontal slide rail 33. The sliding connector 34 includes a C-shaped connecting part 341 and sliding parts 342 located on both sides of the opening of the C-shaped connecting part 341. The upper and lower surfaces of the horizontal slide rail 33 are respectively provided with grooves 332 that extend through the horizontal slide rail 33 along its length. The sliding parts 342 can be placed in the grooves 332 and slide along the length of the grooves 332. The vertical slide rail 32 is then installed onto the horizontal slide rail 33 via the connector, realizing the sliding function of the vertical slide rail 32 along the length of the horizontal slide rail 33. By sliding the vertical slide rail 32 along the length of the horizontal slide rail 33, the range of motion of the instrument housing 1 can be effectively expanded.

[0044] Reference Figure 2 and Figure 6 The specimen imaging device also includes a foot controller 2. The foot controller 2 includes several foot switches 21 and a wireless signal transmitter 23. The foot switches 21 include a positive focus switch 211, a negative focus switch 212, and a photo-taking switch 213; the positive focus switch 211 is used to input a signal to increase the focal length of the acquisition camera 11, and the negative focus switch 212 is used to input a signal to decrease the focal length of the acquisition camera 11; the photo-taking switch 213 is used to input a photo-taking trigger signal from the acquisition camera 11. The MCU 12 is connected to a wireless signal receiver 16 and a speed control module 17. The speed control module 17 is used to adjust the focusing rate of the acquisition camera 11. The speed control module 17 uses a push-button switch mounted on the instrument housing 1. The speed control module 17 includes a positive adjustment switch and a negative adjustment switch. The positive adjustment switch is used to increase the zoom rate of the acquisition camera 11, and the negative adjustment switch is used to decrease the zoom rate of the acquisition camera 11. The foot switch 21 converts the foot pedal signal into an analog signal, which is then transmitted to the wireless signal receiver 16 via the wireless signal transmitter 2. The wireless signal receiver 16 receives the analog signal transmitted by the wireless signal transmitter 23 and sends it to the MCU 12. The MCU 12 then identifies and judges the analog signal to control the acquisition camera 11. With the foot switch 21, operators can easily control the acquisition camera 11 to focus and take pictures by operating the foot switch 21 during sampling operations.

[0045] Reference Figure 6 and Figure 7The camera switch 213 is located between the positive focus switch 211 and the negative focus switch 212. The positive focus switch 211, negative focus switch 212, and camera switch 213 are arranged around the center of a virtual circle O, and the foot switch 21 is arranged radially along the length of the virtual circle O. The upper surface of the foot switch 21 has multiple strip-shaped protrusions 22 along its width. When using the foot controller 2, the operator places their foot in the middle of the foot controller 2. Because the positive focus switch 211, negative focus switch 212, and camera switch 213 are arranged around each other, the operator only needs to make small movements of their foot to switch between the different foot switches 21. The camera switch 213 separates the positive focus switch 211 and the negative focus switch 212, thereby reducing the possibility of the operator using the same switch incorrectly during operation. The strip-shaped protrusions 22 on the upper surface of the foot switch 21 can effectively increase the contact friction between the foot and the foot switch 21 when the operator performs foot operation, making it less likely to slip during operation.

[0046] Example 2:

[0047] A control method for a gross specimen imaging device is provided, employing the gross specimen imaging device described in Example 1. When focusing the acquisition camera 11 of the gross specimen imaging device, a rate adjustment command is input through the speed control module 17, and the MCU 12 adjusts the zoom rate of the acquisition camera 11 according to the rate adjustment command. An operation signal to increase the zoom rate of the acquisition camera 11 is input through a positive adjustment switch, and an operation signal to decrease the zoom rate of the acquisition camera 11 is input through a negative adjustment switch. A press switch converts the operator's pressing action into an analog signal and sends it to the MCU 12. The MCU 12 judges the pressing time information based on the analog signal sent through the press switch, and then adjusts the zoom rate of the acquisition camera 11 accordingly. The MCU 12 judges the foot pedal time information based on the analog signal output by the foot pedal switch 21, and then linearly adjusts the focal length of the acquisition camera 11 based on the foot pedal time information. The MCU12 adjusts the focal length of the acquisition camera 11 according to the stepping time of the foot switch 21, which reduces the precision requirement and makes it easy for the operator to adjust the focus. Furthermore, the zoom rate of the acquisition camera 11 can be adjusted through the speed control module 17, making the operator's focus adjustment of the acquisition camera 11 more accurate.

[0048] The MCU12 pre-generates the image information for the next time point based on the current image information captured by the acquisition camera 11, and sends the pre-generated image information to the display screen 14, which then displays the pre-generated image information. When zooming the acquisition camera 11 using the foot switch 21, there is a certain degree of delay between the actual input by the operator and the real-time display on the display screen 14. By pre-generating the image information for the next time point based on the current image information captured by the acquisition camera 11, the operator can more accurately control the focal length of the acquisition camera 11 when zooming.

[0049] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
