Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to an endoscopic biopsy forceps device. Background Technology

[0002] Biopsy forceps are an indispensable tool in obtaining pathological samples. By gripping mucosal samples from the site of examination, using forceps without a camera reduces the accuracy of sample acquisition, leading to errors in the results. Furthermore, if the biopsy device is too large, it may accidentally scratch and bleed the small area being examined, resulting in impure samples and a series of diagnostic errors. Since some diseased tissues show different colors under white light and under multispectral light, using multispectral illumination better highlights the difference between lesions and normal tissue, thus better assisting doctors in biopsy sampling. Therefore, image-visualized miniature biopsy forceps are increasingly valued by hospitals, and there is a need to find effective and reusable methods to solve the problem of image visualization of biopsy forceps.

[0003] Currently, hospitals use ordinary endoscopic biopsy forceps without image visualization capabilities, and sample acquisition is done blindly. A detachable infrared camera biopsy forceps (patent number 201721302733.6) can easily achieve image visualization. A human anorectal surgery biopsy forceps (patent number 201922160242.8) enables convenient cutting and picking.

[0004] The endoscopic biopsy forceps used in the aforementioned hospitals have limited functionality and lack image visualization capabilities, requiring doctors to rely solely on their experience to blindly obtain samples. This significantly increases the accuracy of sample acquisition. While detachable infrared camera biopsy forceps solve the image visualization problem, they do not address the issue of reusability. Images are simply transmitted to a display screen and cannot be captured and saved in real time. Although human anorectal biopsy forceps offer convenient cutting and picking, they lack visualization capabilities, making the procedure still inherently risky and challenging. Summary of the Invention

[0005] The purpose of this invention is to provide an endoscopic biopsy forceps device, which is a reusable wireless miniature endoscopic biopsy forceps containing a camera device. It can transmit images in real time and display them on a screen for easy observation by doctors, and has the function of real-time screenshotting and retaining useful image information.

[0006] To achieve the above objectives, the present invention proposes an endoscopic biopsy forceps device.

[0007] It includes a handle, a bar, a clamping part, and a monitoring mechanism. The handle is located at the tail of the bar, the clamping part is located at the head of the bar, and the handle controls the clamping part to perform clamping actions through the bar. The monitoring mechanism is located on the bar.

[0008] The clamping bar includes an upper sliding plate and a lower sliding plate that translate relative to each other, and the lower sliding plate is provided with a slot;

[0009] The monitoring mechanism includes a camera, a signal transmission line, a multispectral illumination system, an optical fiber, a signal processing board, and a display device. The camera is fixed in the slot, the output light source of the multispectral illumination system is located on the camera, the camera is connected to the signal processing board through the signal transmission line, the multispectral illumination system is connected to the signal processing board through the optical fiber, the signal processing board is wirelessly connected to the display device, and the signal processing board is connected to the control system.

[0010] The multispectral illumination system includes a light-emitting lens, a color wheel structure A, a beam splitter, a color wheel structure B, and an optical fiber interface arranged in sequence. One end of the optical fiber is connected to the signal processing board to receive the input light, and the other end is connected to the input light through the optical fiber interface. The color wheel structure A and the color wheel structure B are each provided with 12 channels evenly distributed on the circumference. The light-emitting lens is mounted on the camera.

[0011] The control system includes a switching system, a motor drive, an image acquisition system, and a button system. The switching system is used to control the start and stop of the main control computer system. The motor drive is used to control the position rotation of the color wheel structure A and the color wheel structure B. The image acquisition system is used to control the image acquisition of the camera and the image display of the display device. The button system is used to control the adjustment operation of the image acquisition system.

[0012] A flat mirror is provided on the outer side of the light-emitting lens. Of the 12 channels in the color wheel structure B, 10 are filter channels and 2 are white light channels. The filter channels can only pass light with wavelengths of 405nm, 410nm, 415nm, 445nm, 473nm, 500nm, 520nm, 540nm, 550nm, and 600nm, respectively. The 12 channels in the color wheel structure A are filled with fluorescent materials in different proportions. The button system is located at the tail of the clamping rod.

[0013] Furthermore, in the endoscopic biopsy forceps device, the clamping part includes an upper clamp and a lower clamp, the lower clamp is fixedly connected to the lower sliding plate, and the upper clamp is rotatably connected to the front end of the upper sliding plate and the lower sliding plate respectively;

[0014] The clamp handle includes a movable handle, the lower sliding plate is fixedly connected to the movable handle, and the upper sliding plate is drivenly connected to the movable handle through a sliding plate connecting block.

[0015] Furthermore, in the endoscopic biopsy forceps device, the sliding plate connecting block is fixed to the tail of the upper sliding plate by fixing screws, the two handles of the movable handle are rotatably connected by fixing screws, the lower sliding plate is fixedly connected to the rear handle of the movable handle, and the sliding plate connecting block is fixedly connected to the front handle of the movable handle.

[0016] Furthermore, in the endoscopic biopsy forceps device, the hand-held portions of the two forceps of the movable handle are covered with anti-slip rubber.

[0017] Furthermore, in the endoscopic biopsy forceps device, the forceps handle portion also includes a force support, and the force support is provided between the two forceps of the movable handle. The force support ensures that the two forceps of the movable handle always have an elastic thrust that tends to separate from each other. The force support includes two spring pieces that are interlocked to form a leaf spring structure.

[0018] Furthermore, in the endoscopic biopsy forceps device, the signal transmission line is fixed in the slot by a fixing buckle, and both the camera and the signal transmission line are covered with a transparent protective sleeve.

[0019] Furthermore, in the endoscopic biopsy forceps device, the signal processing board is equipped with a battery module, a wireless transmission module, a circuit processing module, an aperture control group, and a signal control line. The circuit processing module is wirelessly connected to the display device through the wireless transmission module. The circuit processing module is connected to the aperture control group and the motor drive through the signal control line, respectively. The aperture control group is used to adjust the aperture size.

[0020] Furthermore, in the endoscopic biopsy forceps device, the aperture control group includes an adjustable focusing imaging lens group and a replaceable polarizing lens. Natural light is filtered by the replaceable polarizing lens, and then the aperture size is adjusted by the adjustable focusing imaging lens group to form the input light connected to the optical fiber. Compared with the prior art, the beneficial effects of the present invention are mainly reflected in: by using a miniature camera with multispectral light source for auxiliary illumination, the acquired image is wirelessly transmitted to the display device. After signal transmission between the transmitting and receiving ends, it is converted into a corresponding image and displayed on the screen. Through the control system, the image can be saved in real time as an auxiliary basis for subsequent detection results. Since the camera is embedded in the slot of the biopsy forceps, the size of the biopsy forceps is reduced, the camera is prevented from falling out, the patient's pain is reduced, and it is more convenient for doctors to operate.

[0021] Meanwhile, both the camera and signal transmission cable are covered with transparent, disposable protective sleeves, preventing high-temperature sterilization and allowing for repeated use of the miniature camera. The camera's multispectral illumination system enhances video clarity during testing, and the different wavelengths of the spectrum provide varying observation effects, making it easier to distinguish diseased tissues and allowing doctors to better observe lesions and accurately extract target tissue samples. A button system at the tail of the forceps handle facilitates saving useful information and zooming in / out of relevant data. The handle of the biopsy forceps is reinforced with anti-slip rubber for good stability. Attached Figure Description

[0028] The endoscopic biopsy forceps device of the present invention will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of the invention. It should be understood that those skilled in the art can modify the invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the invention.

[0029] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0030] The invention is described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0031] like Figures 1 to 2 As shown, the present invention proposes an endoscopic biopsy forceps device, including a forceps handle, a forceps bar, a forceps clamping part, and a monitoring mechanism. The forceps handle is located at the tail of the forceps bar, and the forceps clamping part is located at the head of the forceps bar. The forceps handle controls the forceps clamping part to perform clamping actions through the forceps bar. The monitoring mechanism is located on the forceps bar.

[0032] Among them, such as Figures 2 to 3 As shown, the clamping bar includes an upper sliding plate 7 and a lower sliding plate 11 that translate relative to each other, and the lower sliding plate 11 has a slot 12 on its side; as Figures 1 to 2 As shown, the clamping part includes an upper clamp 6 and a lower clamp 8. The lower clamp 8 is fixedly connected to the lower sliding plate 11, and the upper clamp 6 is rotatably connected to the front end of the upper sliding plate 7 and the lower sliding plate 11 respectively.

[0033] Furthermore, such as Figure 1 As shown, the clamp handle includes a movable handle 3 and a force-bearing bracket 2. The lower sliding plate 11 is fixedly connected to the movable handle 3, and the upper sliding plate 7 is drivenly connected to the movable handle 3 through a sliding plate connecting block 5. Specifically, as shown... Figure 1 As shown, the sliding plate connecting block 5 is fixed to the tail of the upper sliding plate 7 by fixing screw 4, the two clamps of the movable handle 3 are rotatably connected by fixing screw 4, the lower sliding plate 11 is fixedly connected to the rear clamp of the movable handle 3, and the sliding plate connecting block 5 is fixedly connected to the front clamp of the movable handle 3.

[0034] Furthermore, such as Figure 1As shown, a force-bearing bracket 2 is provided between the two handles of the movable handle 3. The force-bearing bracket 2 ensures that the two handles of the movable handle 3 always have an elastic thrust that tends to separate from each other. The force-bearing bracket 2 consists of two spring pieces that are interlocked to form a leaf spring structure. The handheld parts of the two handles of the movable handle 3 are covered with anti-slip rubber 1, which provides good anti-slip and fixation. The handles of the movable handle 3 adopt a semi-enclosed fixation structure, which can effectively alleviate numbness and stiffness of the user's fingers caused by prolonged fixation and avoid medical accidents.

[0035] At the same time, such as Figures 2 to 3 As shown, the monitoring system includes a camera 10, a signal transmission line 15, a multispectral illumination system, an optical fiber 29, a signal processing board, and a display device. The camera 10 is connected to the signal processing board via the signal transmission line 15, and the signal processing board is wirelessly connected to the display device. Image acquisition by the camera 10 is achieved wirelessly, with data and images transmitted and processed wirelessly through a transmitter and receiver. Both the camera 10 and the signal transmission line 15 are fixed in place within the slot 12 using clips 14, allowing for camera 10 removal and replacement, and effectively reducing the overall size of the biopsy forceps. Both the camera 10 and the signal transmission line 15 are covered with transparent protective sleeves 13, providing secondary protection, reducing the risk of cross-contamination, and increasing the reusability of the camera 10.

[0036] Furthermore, such as Figures 2 to 3 As shown, the output light source of the multispectral illumination system is located on the camera 10. The multispectral illumination system is connected to the signal processing board through the optical fiber 29. With the auxiliary illumination of the light source, the observation of the tissue to be detected can be greatly improved in the absence of light inside the human body. This further solves the problem that diseased tissue is not easy to identify under white light. The signal processing board is connected to the control system and can control the image saving and spectral adjustment, which makes it convenient for doctors to conduct real-time observation and retain clear images for reference.

[0037] Specifically, the multispectral illumination system includes a planar mirror 9, a light-emitting lens 24, a color wheel structure A25, a beam splitter 27, a color wheel structure B26, an optical fiber interface 28, and an aperture control group. The light-emitting lens 24 is mounted on the camera 10, and the planar mirror 9 is located outside the light-emitting lens 24. One end of the optical fiber 29 connected to the signal processing board receives input light through the aperture control group, and the other end of the optical fiber 29 receives input light through the optical fiber interface 28. The color wheel structure A25, beam splitter 27, and color wheel structure B26 are sequentially positioned between the light-emitting lens 24 and the optical fiber interface 28. The aperture control group adjusts and controls the aperture size of the natural light. The input light is received through the optical fiber 29, and through the cooperation of the color wheel structure A25, beam splitter 27, and color wheel structure B26, light of different wavelengths is obtained after passing through different types of filters. This light is then output from the structure containing the light-emitting lens 24 and the planar mirror 9, serving as the output light source mounted on the camera 10.

[0038] Furthermore, such as Figure 4 and Figure 5 As shown, the control system includes a switch system, a motor drive (not shown), an image acquisition system, and a button system 23. The switch system is used to control the opening and closing of the main control computer system, which includes a display device. The motor drive is used to control the position rotation of the color wheel structure A25 and the color wheel structure B26. The image acquisition system is used to control the image acquisition of the camera 10 and the image display of the display device. The button system 23 is used to control the adjustment operation of the image acquisition system, and the button system 23 is located at the tail of the clamping bar.

[0039] Furthermore, such as Figure 3 As shown, the signal processing board includes a battery module 16, a wireless transmission module 17, a circuit processing module 18, an aperture control group, and a signal control line 20. The circuit processing module 18 is wirelessly connected to the display device via the wireless transmission module 17. The circuit processing module 18 is also connected to the aperture control group via the signal control line 20, allowing adjustment of the aperture size. Furthermore, the circuit processing module 18 is connected to a motor drive via the signal control line 20, controlling the rotation positions of color wheel structures A25 and B26 to coordinate with the beam splitter 27 and obtain light of different wavelengths. The signal processing board uses the wireless transmission module 17 for wireless data transmission and has a separately powered battery module 16, enabling completely independent wireless remote transmission. The display devices include a PC display screen 21 and a mobile terminal display screen 22.

[0040] Furthermore, such as Figure 3 As shown, the aperture control group includes a focusable imaging lens group 30 and a replaceable polarizing lens 31. Natural light is filtered by the replaceable polarizing lens 31 and then the aperture size is adjusted by the focusable imaging lens group 30 to form the input light that enters the optical fiber 29.

[0041] In addition, the lower sliding plate 11 has a placement box 19 at its tail, and the signal processing board and aperture control group are both located in the placement box 19. The placement box 19 is provided with an adjustment part for easy adjustment of the adjustable focusing imaging lens group 30 and a window for replacing the replaceable polarizing lens 31 and introducing natural light.

[0042] Furthermore, such as Figure 2 and Figure 4As shown, color wheel structures A25 and B26 each have 12 channels evenly distributed on their circumference. Of the 12 channels in color wheel structure B26, 10 are filter channels and 2 are white light channels. The filter channels can only allow light with wavelengths of 405nm, 410nm, 415nm, 445nm, 473nm, 500nm, 520nm, 540nm, 550nm, and 600nm, respectively. The 12 channels in color wheel structure A25 are filled with fluorescent materials in different proportions. The specific implementation is as follows:

[0043] By applying pressure to the movable handle 3, the sliding plate connecting block 5 controls the back-and-forth movement of the upper sliding plate 7 and the lower sliding plate 11, thereby changing the opening and closing angles of the upper clamp 6 and the lower clamp 8 to achieve the result of clamping the target sample tissue. The camera 10 transmits image data to the signal processing board via the signal transmission line 15, and the images captured by the camera 10 can be displayed on the PC display screen 21 and the mobile terminal display screen 22. The system can also perform operations such as image capture, video recording, and image zooming via the button system 23, ensuring that the saved images and videos can be viewed at any time later.

[0044] The signal processing board is fixed in the placement box 19. The circuit processing module 18 acquires image-related data through signal transmission lines 15 soldered to corresponding pads, and performs related data transmission and processing with the display device of the PC or mobile terminal via low-power, low-data-rate Wi-Fi wireless communication as a wireless transmission module 17, so that the image is displayed on the screen in real time. Furthermore, the display device can control the real-time image acquisition, facilitating the capture of useful images for later diagnostics.

[0045] Because the biopsy forceps in this application are designed for miniaturization, they are powered by a small lithium battery fixed in the battery module 16 during the operation of the entire signal processing board. The related components are also low-power and energy-saving, and the battery is fixed by a battery clip, making it difficult to fall off.

[0046] In summary, the endoscopic biopsy forceps device proposed in this embodiment wirelessly transmits the acquired images to the display device via a miniature camera. After signal transmission between the transmitting and receiving ends, the images are converted into corresponding pictures and displayed on the screen. The images can be saved in real time as an auxiliary basis for later detection results. Since the camera is embedded in the slot of the biopsy forceps, the size of the biopsy forceps is reduced, the camera is prevented from falling out, the patient's pain is reduced, and it is more convenient for doctors to operate.

[0047] Meanwhile, both the camera and signal transmission cable are covered with transparent, disposable protective sleeves, preventing high-temperature sterilization and allowing for repeated use of the miniature camera. The camera's built-in LED light improves video clarity during testing, facilitating better observation of lesions and accurate extraction of target tissue samples by doctors. The biopsy forceps handles are reinforced with anti-slip rubber for effective fixation.

[0048] The above are merely preferred embodiments of the present invention and do not constitute any limitation on the present invention. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and content disclosed in the present invention without departing from the scope of the present invention shall be deemed to have remained within the protection scope of the present invention.
