Description

Technical Field

[0001] The utility model belongs to the field of endoscope control, and in particular relates to an endoscope foot control device. Background Art

[0002] An endoscope is an inspection device that enters the stomach through the mouth or other natural channels to directly observe the condition of internal organs. It can make up for the shortcomings of external perspective inspection technologies such as X-rays and magnetic resonance imaging. Endoscopes integrate traditional optics, ergonomics, precision machinery, modern electronics, mathematics, software and other technologies. Endoscopes are mainly composed of image sensors, optical lenses, light sources, mechanical devices and other devices. The existing medical endoscope camera system is a split combination system, which is composed of four independent hosts, namely a camera, a display, a light source, and an image recorder. The endoscope is connected to the camera head of the camera through an optical adapter, and is connected to the light source through an optical fiber transmission line to achieve endoscope lighting.

[0003] When using an endoscope, inspection workers usually need two people to cooperate in order to operate the endoscope. One person is mainly used to operate the position and angle of the lens, and the other person is used to assist in the endoscope's video / water sampling control work. When two people cooperate to use an endoscope, on the one hand, communication is prone to deviations, and on the other hand, it has an adverse effect on the efficiency of the inspection work. For this reason, the prior art also provides some technical solutions for controlling the endoscope camera by foot pedals, so that the inspector can complete the endoscope inspection work alone, thereby improving the accuracy and efficiency of the inspection work. However, the conventional endoscope camera foot pedal control device in the prior art is usually composed of multiple foot pedals, and the inspector is prone to stepping on the wrong pedal. In addition, the existing endoscope foot pedal control device also has the disadvantages of insufficient sensitivity, easy failure after long-term use, and difficult to replace after failure.

[0004] To this end, the utility model patent with authorization announcement number CN207492744 U discloses "an endoscope camera foot-operated control device", which includes an endoscope host, an endoscope camera or a computer that receives graphic information from the endoscope host and a camera control pedal, wherein the endoscope camera is provided with a camera data line, a camera power line and a camera control line; the camera control pedal includes a pedal mounting base plate and a flip control pedal, one end of the pedal mounting base plate is provided with a pedal mounting shaft, and the other end of the pedal mounting base plate is provided with a pedal control side wall, one end of the flip control pedal forms a hinge structure with the pedal mounting base plate through the pedal mounting shaft, and the other end of the flip control pedal faces the pedal control side wall; a pedal return spring is provided between the pedal mounting base plate and the flip control pedal, and a plurality of control buttons are provided from top to bottom on a side surface of the pedal control side wall facing the flip control pedal. The endoscope camera foot control device can facilitate the inspector to complete the endoscope inspection operation alone, thereby improving the accuracy and efficiency of the inspection operation, and can prevent the inspector from stepping on the wrong pedal during foot control; and through the camera control line, the camera control pedal is directly connected to the computer that receives the graphic information of the endoscope host instead of the endoscope host, which can improve the sensitivity of the endoscope foot control device. Since the number of electronic components involved is greatly reduced, the reliability of the relevant system is improved, and it is not easy to fail after long-term use, and the endoscope foot control device is easy to replace after failure.

[0005] However, the above-mentioned endoscope camera foot pedal control device is connected to the endoscope host or the computer that receives the graphic information of the endoscope host through a wired connection. During the endoscopic inspection, the inspection operator not only needs to operate the endoscope camera foot pedal control device, but also other foot pedal control devices, such as the water sampling foot pedal control device. As the number of foot pedal control devices increases, the use of wired connection will inevitably cause the lines to be tangled and confusing. Utility Model Content

[0025] The present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0026] See also Figure 1-Figure 6 The utility model of the endoscope foot control device comprises a base plate 1, a plurality of foot controllers arranged on the base plate 1, the foot controller comprises a base, a pedal arranged on the base and a circuit control system, wherein the base is mounted on the base plate 1, and the pedal is mounted on the base; the circuit control system comprises a transmitting module and a power supply module; the transmitting module and the power supply module are mounted in a control box, and the control box is mounted on the base, wherein the transmitting module is used to transmit control instructions, and the transmitting frequency of the transmitting module of the image collecting foot controller is a 2.4G radio frequency frequency; the transmitting frequency of the transmitting module of the water collecting foot controller is a 315MHz radio frequency frequency, with strong anti-interference ability and stable signal transmission, even the high-frequency surgical system frequently used in the gastrointestinal endoscopy room cannot affect the normal use of the foot controller of this embodiment; a receiving module is installed on the endoscope host or the computer and medical water pump machine that receive the graphic information of the endoscope host, which is used to receive the control instructions transmitted by the transmitting module.

[0027] See also Figure 1-Figure 6The power supply module includes a power module and a charging module, wherein the power module is powered by a lithium battery, the lithium battery is 3000mA, and the lithium battery has the advantage of long battery life. In actual use, it can be used for about 40 days from full charge to use until the power indicator starts to prompt low power; in addition, the lithium battery has a fast charging speed, generally only takes 2 hours to be fully charged, and can be used while charging with a charger or a power bank, without delaying use; the charging module includes a 5V TYPE-C standard charging interface arranged on the foot controller, which can facilitate the charging and use of any mobile phone charger, and is also equipped with a charging indicator light to observe the charging status in real time.

[0028] See also Figure 1-Figure 6 The foot controller is divided into a water sampling foot controller 2 and a map sampling foot controller 3, wherein:

[0029] The receiving module corresponding to the water sampling foot controller 2 is installed on the medical water pump machine. The receiving module is powered by 220V voltage and uses a high-efficiency relay to replace the foot switch in the medical water pump machine to completely achieve power isolation. The switch mode can be switched in three modes: inching mode, self-locking mode, and interlocking mode; it can meet the needs of various medical water pump machines; in addition, the receiving module is equipped with two strong magnetic screws, which can be easily adsorbed on the body of the medical water pump machine;

[0030] The receiving module corresponding to the image-taking foot controller 3 is installed on the endoscope host or the computer that receives the image and text information of the endoscope host. The receiving module is connected to the computer via USB. Combined with special configuration software, it can define the output of each key value of the keyboard and mouse, simulate each button of the keyboard and mouse, including single button and combination button. The image-taking pedal (that is, the pedal in the image-taking foot controller 3) can be paired with the receiving end one-to-one or many-to-one, which can perfectly adapt to the different shortcut key requirements of various image and text software. This receiving module outputs F4 by default; in addition, the image-taking foot controller 3 also uses a switch anti-shake chip. When the image-taking pedal is stepped on once, the receiving module outputs F4 once, thereby realizing the wireless control of the image-taking action of the image-taking software.

[0031] See also Figure 1-Figure 6 The bottom plate 1 adopts PVC soft glass pad. Since the PVC soft glass pad has certain anti-slip and maneuverability, the preset porous positions can flexibly install two sets of foot controllers to meet the user's usage habits. At the same time, the pedals in the water sampling foot controller 2 and the image sampling foot controller 3 are distinguished by different colors with strong contrast, thereby reducing the chance of accidental stepping during use.

[0032] In this embodiment, the image collecting foot controller 3 is also provided with a wired / wireless setting lever switch and a standard aviation connector to facilitate the connection of the wired foot controller and easily realize the wired / wireless switching.

[0033] like Figure 5 As shown, Figure 5 The circuit diagram of the foot controller 3 is shown below;

[0034] The wired / wireless setting lever switch in the figure can be used to switch the wired / wireless mode of the picture-taking foot controller 3. When it is adjusted to the wired mode, the picture-taking foot controller 3 only provides a mechanical switch function, and is connected to the corresponding wired switch module through a wired interface to realize the wired foot function; when it is adjusted to the wireless mode and the main switch is closed, the power module supplies power to the transmitting module (i.e., the transmitter in the figure), and the power indicator simultaneously detects the current battery power. When the power indicator displays a blue light, it indicates that the battery power is sufficient; if the power indicator displays a red light, it indicates that the battery power is insufficient. At this time, a conventional mobile phone charger or a TYPE-C port of a power bank can be used to connect to the charging input port. The charging process of the battery is managed by the charging module. The charging indicator light displays a red light during charging, and a blue light when fully charged, and the charging is automatically cut off to protect the battery and avoid overcharging; in this embodiment, the power module uses a 18650 lithium battery, and the circuit can be charged and used at the same time. The switch anti-shake chip in the figure can effectively eliminate the jitter phenomenon of the mechanical switch and convert the mechanical switch signal into an electrical signal. When the foot switch is closed, pin 3 in the switch anti-shake chip outputs a low level, triggering the transmitter to transmit the signal. When the foot switch is disconnected, pin 3 of the switch anti-shake chip outputs a high level, and the transmitter stops transmitting the signal, thereby achieving an accurate one-to-one relationship between the foot switch and the transmitter; each time the foot switch is closed and disconnected, the transmitter transmits a signal, and the receiver outputs F4 on the computer once, realizing sampling. Figure 1 Second-rate.

[0035] In addition, the working mode of the image acquisition foot controller 3 can be set according to actual needs. The receiver (i.e., the receiving module) can modify any key and combination key on the analog output keyboard, including the left and right mouse buttons, etc., through the configuration software. It can realize single output (the foot switch is closed and opened once, and only outputs once), and can also realize continuous output (when the foot switch is closed, the output is continuous until the foot switch is disconnected).

[0036] like Figure 6 As shown, Figure 6 It is the circuit schematic diagram of the water sampling foot controller 2;

[0037] When the main switch is closed, the power module supplies power to the transmitting module (i.e., the transmitter in the figure), and the power indicator simultaneously detects the current battery power. When the power indicator displays a blue light, it indicates that the battery power is sufficient; if the power indicator displays a red light, it indicates that the battery power is insufficient. At this time, a conventional mobile phone charger or a TYPE-C port of a power bank can be used to connect the charging input port. The charging process of the battery is managed by the charging module. The charging indicator light displays a red light during charging, and a blue light when fully charged, and the charging is automatically cut off to protect the battery and avoid overcharging; in this embodiment, the power module uses two 18650 lithium batteries and can achieve balanced charging. This circuit can be used while charging. When the foot switch is closed, the transmitter is powered on and transmits a signal. After the receiver (i.e., the receiving module) receives the signal, the switch is closed, and the medical water pump continues to pump water; when the foot switch is disconnected, the transmitter is powered off, stops transmitting signals, the receiver switch is disconnected, and the medical water pump stops pumping water (inching mode).

[0038] In this embodiment, the working mode of the water sampling foot controller 2 can be set according to actual needs. The receiver can realize different working modes by setting the "working mode switching area" on the circuit board, including: inching mode, self-locking mode, and interlocking mode.

[0039] Inching mode: When the foot switch is closed, the receiver switch is closed; when the foot switch is disconnected, the receiver switch is disconnected;

[0040] Self-locking mode: The foot switch is closed and opened once, and the receiver switch remains closed after closing. The foot switch is closed and opened again once, and the receiver switch remains open after opening.

[0041] Interlocking mode: Foot switch No. 1 is closed and opened once, and the receiver switch No. 1 remains in the closed state after closing, and switch No. 2 is in the open state; foot switch No. 2 is closed and opened once, and the receiver switch No. 1 is opened and remains in the open state, and switch No. 2 is closed and closed.

[0042] In addition to the above-mentioned embodiments, the image-collecting foot controller 3 can support custom simulation of any key of keyboard and mouse through configuration software, support multi-function key combination trigger (such as Ctrl+Alt+Delete), key value configuration can be saved after power failure (no need to reconfigure after unplugging and plugging after configuration), and support single output. It can be widely used in automatic office, custom keyboard and mouse, medicine, chemical industry, meteorology, environmental protection, electronics, navigation, surveying and mapping, laboratory, etc. At present, the device and combination are mainly used for the image-collecting function of the computer graphic system of hospital endoscope wireless control (it can be personalized according to the shortcut keys of each graphic software). The water-collecting foot controller 2 can realize three switching modes of self-locking, inching and interlocking through the built-in relay at the receiving end, and the switch is isolated from the receiver line, and the lines do not interfere with each other. It can be widely used in the switches of various electrical appliances, such as lamps, electric doors, windows, lifting equipment, gates, lifts, industrial control and security industries. At present, the device and combination are mainly used for hospital endoscope wireless control of endoscope water delivery pump to achieve the function of freely controlling water delivery according to inspection needs.

[0043] The above is a preferred implementation mode of the present invention, but the implementation mode of the present invention is not limited by the above content. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
