Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and in particular to an endoscope flushing and suction device. Background Technology

[0002] In current clinical surgeries, some procedures requiring endoscopic intervention, such as ureteroscopic lithotripsy, necessitate endoscopes with both irrigation and suction functions. Currently, there are two main types of endoscopes integrating irrigation and suction functions: one design features separate irrigation and suction modules connected to the endoscope individually; the other integrates both modules into a single device, using a built-in fluid supply and negative pressure system for irrigation and suction. Both approaches have drawbacks in practical application. Separate irrigation and suction modules require multiple medical personnel, increasing operating costs and making them unsuitable for scenarios requiring rapid response control. Furthermore, the negative pressure of separate suction modules is directly provided by the central negative pressure system in the operating room, making direct control via the endoscope's operating handle difficult. Integrated irrigation and suction modules typically introduce a new suction negative pressure supply device, increasing equipment costs and wasting the hospital's central negative pressure resources. Utility Model Content

[0003] The purpose of this invention is to provide an endoscopic irrigation and suction device that is simple in structure, easy to operate, and avoids the waste of negative pressure resources in hospitals.

[0004] To achieve this objective, the present invention adopts the following technical solution: an endoscopic irrigation and suction device, comprising an endoscope handle, an irrigation pump, and a control assembly. The endoscope handle is provided with an irrigation inlet and a suction inlet. The irrigation pump includes a housing, a control valve, and a pump body. The control valve is disposed within the housing, and the pump body is installed within the housing. The side wall of the housing is provided with two first connectors. The input end of the control valve is connected to the central negative pressure outlet pipeline of the operating room through one of the first connectors, and the output end of the control valve is connected to the suction inlet pipeline through the other first connector. The output end of the pump body is connected to the irrigation inlet. The control assembly includes a controller and a processor. The controller is disposed within the housing and electrically connected to the control valve and the pump body respectively. The processor is disposed within the endoscope handle and electrically connected to the controller. The endoscope handle is provided with two first rotary switches, both of which are electrically connected to the processor to control the control valve and the pump body respectively.

[0005] Preferably, the housing is provided with two second rotary switches, both of which are electrically connected to the controller.

[0006] Preferably, the pump body is configured as a peristaltic pump, which includes a mounting base, a planetary carrier, and an infusion tube. The mounting base is fixed to the side wall of the housing and has a mounting groove. The planetary carrier is rotatably connected to the mounting base and confined within the mounting groove. Three pressure rollers are spaced apart on the planetary carrier. The infusion tube is pressed between the pressure rollers and the inner wall of the mounting groove. The mounting base is connected to two second connectors. The input end and output end of the infusion tube are respectively connected to the two second connectors.

[0007] Preferably, the peristaltic pump is located on the front side of the housing and the top of the peristaltic pump is tilted backward.

[0008] Preferably, the first connector and the second connector are respectively positioned opposite to each other on both sides of the housing.

[0009] Preferably, the top wall of the housing is provided with a display, which is electrically connected to the controller.

[0010] Preferably, the endoscope handle includes a handle body and a suction sheath, the handle body and the suction sheath are connected, the handle body is provided with a first conduit, the flushing inlet is opened in the first conduit, and the suction inlet is opened at the end of the suction sheath.

[0011] Preferably, the endoscope handle is provided with a second conduit, the irrigation inlet is opened in the second conduit, a branch tube is provided on one side of the second conduit, and the suction inlet is opened in the branch tube.

[0012] Preferably, a handle groove is provided on one side of the housing.

[0013] Preferably, the first connector is configured as a pagoda-shaped barbed connector.

[0014] The beneficial effects of this invention are as follows: When using the endoscopic irrigation and suction device, the user directly rotates the first knob switch on the endoscope handle. The first knob switch and the processor work together to send a control signal. The controller responds to the control signal, thereby controlling the operation of the corresponding control valve and pump body switch, realizing the on / off control and flow regulation of the irrigation fluid in the irrigation inlet, as well as the on / off control and magnitude regulation of the negative pressure in the suction inlet. By setting up an irrigation pump and control components, the control valve for controlling the negative pressure and the pump body for controlling the irrigation fluid are integrated into the same irrigation pump, and the two first knob switches are integrated into the endoscope handle. Irrigation and suction functions can be achieved using a single irrigation pump. Furthermore, the user can quickly control and adjust the control valve and pump body on the endoscope handle, saving equipment costs and improving ease of use. In addition, the control valve directly utilizes the hospital's existing negative pressure resources, eliminating the need for a new negative pressure supply device, simplifying the irrigation pump structure and avoiding waste of the hospital's negative pressure resources.

[0029] Reference Figures 1 to 6 As shown, the endoscopic irrigation and suction device provided according to the embodiments of this application includes an endoscope handle 100, an irrigation pump 200 and a control component 300. The endoscope handle 100 is provided with an irrigation inlet 112 and a suction inlet 121.

[0030] The flushing pump 200 includes a housing 210, a control valve 220, and a pump body 230. The control valve 220 is disposed within the housing 210, and the pump body 230 is mounted on the housing 210. Two first connectors 211 protrude from the side wall of the housing 210. The input end of the control valve 220 is connected to the central negative pressure outlet pipeline of the operating room through one of the first connectors 211, and the output end of the control valve 220 is connected to the suction inlet 121 pipeline through the other first connector 211. The output end of the pump body 230 is connected to the flushing inlet 112, and the input end of the pump body 230 is connected to the cleaning fluid supply device. The control assembly 300 includes a controller 310 and a processor. The controller 310 includes a control unit and a first circuit board for mounting the control unit. The processor includes a processing unit and a control circuit board for mounting the processing unit. The controller 310 is disposed within the housing 210 and electrically connected to the control valve 220 and the pump body 230, respectively. The processor is disposed within the endoscope handle 100 and electrically connected to the controller 310.

[0031] Specifically, the rear wall of the housing 210 is provided with a first control interface 216, and the bottom wall of the housing 210 is provided with a heat dissipation vent. The first control interface 216 is connected to the controller 310, and the endoscope handle 100 is provided with a second control interface, which is connected to the processor. The first control interface 216 and the second control interface are electrically connected through a wire 113. The endoscope handle 100 is provided with two first rotary switches 130, both of which are electrically connected to the processor. One of the first rotary switches 130 can cooperate with the processor to send a flushing control signal, and the other first rotary switch 130 can cooperate with the processor to send a negative pressure control signal. The two first rotary switches 130 respectively control the control valve 220 and the pump body 230.

[0032] The control valve 220 is configured as an electromagnetic distribution valve. Since electromagnetic distribution valves are mature technologies, diverse in type, and not the focus of this application, the structure of the control valve 220 is not specifically limited here. The housing 210 also has a built-in mobile power supply 240, which is electrically connected to the controller 310, the control valve 220, and the pump body 230.

[0033] In some embodiments, the first rotary switch 130 includes an integrated switch. In this case, the first rotary switch 130 adopts a push-button design. Before rotation, it needs to be pressed to unlock, triggering a start signal to start the corresponding control valve 220 and pump body 230. When rotated in the reverse direction to the initial position, a stop signal is triggered to stop the corresponding control valve 220 and pump body 230, realizing integrated switch operation. In other embodiments, the first rotary switch 130 includes an independent switch button and a knob. The user presses the switch button to trigger a start or stop signal, and rotates the knob to trigger an adjustment signal. The push-button switch is only responsible for turning the machine on and off, and the knob is only responsible for flow / pressure adjustment.

[0034] The knob portion of the first rotary switch 130 can be configured as a photoelectric knob, meaning that the first rotary switch 130 integrates a photoelectric encoder disk with alternating light-transmitting and light-blocking areas on the disk surface. When the user rotates the first rotary switch 130, the optical path between the infrared transmitter and receiver is periodically switched on and off, generating pulse signals. The processor analyzes the rotation direction and angle and converts them into control signals, which are then sent to the controller 310. Alternatively, the knob portion of the first rotary switch 130 can be configured as a magnetic knob, meaning that the first rotary switch 130 integrates a magnetic ring, which interacts with a Hall effect sensor on the processor. With the cooperation of sensors, when the user rotates the first rotary switch 130, the change in magnetic poles triggers the Hall element to output an analog signal. This signal is then used by an ADC (Analog-to-Digital Converter) to obtain a precise angle value, which is converted into a control signal and sent to the controller 310. Alternatively, the knob portion of the first rotary switch 130 can be configured as a contact knob, meaning it has a conductive copper ring that engages with fixed contacts on the processor. When the user rotates the first rotary switch 130, the conductive copper ring sequentially connects with multiple fixed contacts, forming graded contacts and triggering a preset control signal output. The specific structure of the first rotary switch 130 is not limited here, as long as it can control the opening and closing of the corresponding control valve 220 and pump body 230, or change their opening degree.

[0035] Understandably, when a user uses the endoscopic irrigation and suction device, they directly turn the first rotary switch 130 on the endoscope handle 100. The first rotary switch 130, in conjunction with the processor, sends a control signal. The controller 310 responds to the control signal, thereby controlling the corresponding control valve 220 and pump 230 to operate. This achieves on / off control and flow regulation of the irrigation fluid in the irrigation inlet 112, as well as on / off control and adjustment of the negative pressure in the suction inlet 121. Specifically, when the control valve 220 is activated, the negative pressure at the central negative pressure outlet of the hospital operating room can be guided to the suction inlet 121 through the first connector 211, causing negative pressure to be generated in the endoscope handle 100. Turning the first rotary switch 130 corresponding to the control valve 220 can adjust the opening of the control valve 220, thereby controlling the magnitude of the negative pressure. When the pump body 230 is started, the cleaning fluid can be guided to the flushing inlet 112, causing the endoscope handle 100 to spray out the cleaning fluid. By turning the first knob switch 130 corresponding to the pump body 230, the opening degree of the pump body 230 can be adjusted, thereby controlling the pressure of the cleaning fluid outlet.

[0036] By incorporating a flushing pump 200 and a control assembly 300, the control valve 220 for controlling negative pressure and the pump body 230 for controlling the flushing fluid are integrated into the same flushing pump 200. Two first rotary switches 130 are integrated onto the endoscope handle 100. This allows for both flushing and suction functions to be achieved with a single flushing pump 200. Furthermore, the user can quickly control and adjust the control valve 220 and pump body 230 from the endoscope handle 100, saving equipment costs and improving ease of use. The built-in power supply 240 allows the flushing pump 200 to be used externally, ensuring its operation even in situations of unstable power supply or power outages, thus improving its fault tolerance. In addition, the control valve 220 directly utilizes existing negative pressure resources in the hospital, eliminating the need for a new negative pressure supply device, simplifying the structure of the flushing pump 200 and preventing the waste of the hospital's negative pressure resources.

[0037] It should be noted that the housing 210 is provided with two first control interfaces 216. When using the flushing pump 200, the user can connect to the endoscope handle 100 through one first control interface 216 and connect to an external power source through the other first control interface 216 to achieve "flushing while in use" and improve the working stability of the flushing pump 200.

[0038] Furthermore, the first connector 211 is configured as a pagoda-shaped barb connector. Specifically, the outer peripheral wall of the pagoda-shaped barb connector is provided with multiple conical barbs, which are arranged axially along the first connector 211. With the pagoda-shaped barb connector, the user can first connect the pipe to the pagoda-shaped barb connector, and then put the sealing gasket on the barbs to fix the pipe.

[0039] By incorporating a pagoda-shaped barbed connector, the first connector 211 can quickly secure the pipe through the barbed structure and ensure the stability of the pipe connection. In other embodiments, the outer peripheral wall of the first connector 211 is also provided with a threaded structure, allowing the first connector 211 to be threadedly connected to the pipe, thereby improving the ease of pipe installation and removal.

[0040] Reference Figure 1 and Figure 2 As shown, it can be understood that the endoscope handle 100 includes a handle body 110 and a suction sheath 120. The handle body 110 and the suction sheath 120 are connected. The handle body 110 is provided with a first conduit 111, a flushing inlet 112 is opened in the first conduit 111, and a suction inlet 121 is opened at the end of the suction sheath 120.

[0041] By setting up the suction sheath 120, when the control valve 220 controls the negative pressure to connect to the suction inlet 121, the suctioned blood clots and other highly viscous foreign objects can be introduced into the suction sheath 120, which facilitates subsequent cleaning and avoids contamination of the flushing pipe.

[0042] In other embodiments, the endoscope handle 100 is provided with a second conduit, a flushing inlet 112 is provided in the second conduit, a branch tube is provided on one side of the second conduit, and a suction inlet 121 is provided in the branch tube.

[0043] Integrating the flushing inlet 112 and the suction inlet 121 onto the same second catheter simplifies the structure of the endoscope handle 100, reducing the cost of the endoscope handle 100 while meeting basic suction requirements.

[0044] After the suction tube and the first connector 211 are connected, the suction tube can be selectively connected to the suction inlet 121 on the suction sheath 120 or to the suction inlet 121 on the second catheter, depending on the type of endoscope handle 100. No additional connecting tubing is required, which effectively improves the practicality of the flushing pump 200.

[0045] Reference Figure 3 As shown, it can be understood that the top wall of the housing 210 is provided with a glass cover 214 and a display 213. The display 213 is located below the glass cover 214 and is electrically connected to the controller 310. The input and output ends of the control valve 220 are provided with pressure sensors, and the input and output ends of the pump body 230 are provided with flow sensors. The pressure sensors and flow sensors are electrically connected to the controller 310 respectively.

[0046] By setting up the display 213, the controller 310 can display information such as the inlet and outlet pressures of the control valve 220 and the inlet and outlet flow rates of the pump body 230 on the display 213, facilitating timely control and adjustment by the user and effectively improving the user experience. Optionally, the front of the display 213 is tilted downwards for easier viewing, further enhancing the user experience.

[0047] Furthermore, the housing 210 is provided with two second rotary switches 212. The structure and control method of the second rotary switches 212 are the same as those described above regarding the first rotary switch 130, and will not be repeated here. Both second rotary switches 212 are electrically connected to the controller 310. In this embodiment, the second rotary switches 212 and the display 213 are located on the same side of the housing 210.

[0048] By setting a second rotary switch 212, the user can control the control valve 220 and the pump body 230 respectively through the two second rotary switches 212. This can serve as a substitute when the first rotary switch 130 on the handle 100 fails, increasing control redundancy and further improving the fault tolerance of the flushing pump 200.

[0049] Reference Figure 3 and Figure 4As shown, the pump body 230 is configured as a peristaltic pump, which includes a mounting base 231, a planetary carrier 232, and an infusion tube (medical-grade tubing). The mounting base 231 is fixed to the side wall of the housing 210 and has a mounting groove. The planetary carrier 232 is rotatably connected to the mounting base 231 and confined within the mounting groove. The planetary carrier 232 has three pressure rollers 233, which are spaced apart circumferentially along the planetary carrier 232 and rotatably connected to it. The infusion tube is pressed between the pressure rollers 233 and the inner wall of the mounting groove. The mounting base 231 is connected to two second connectors 234, and the infusion tube's input and output ends are respectively connected to the two second connectors 234. The housing 210 houses a drive motor 235, the output end of which is axially fixed to the planetary carrier 232. The control board 236 of the drive motor 235 is electrically connected to the controller 310.

[0050] By configuring the pump body 230 as a peristaltic pump, the flushing fluid only comes into contact with the disposable infusion tubing throughout the entire process, completely isolating it from the pump body 230 to ensure sterile delivery and avoid cross-infection between patients. Furthermore, the peristaltic pump offers stable control, rapid on / off switching, and no risk of leakage. The flow rate can also be precisely adjusted by regulating the speed of the drive motor 235, effectively improving the control accuracy and operational stability of the pump body 230.

[0051] Furthermore, the peristaltic pump is located on the front side of the housing 210, with its top end tilted backward. At this time, the drive motor 235 is tilted within the housing 210, following the peristaltic pump.

[0052] By tilting the peristaltic pump, the length of the flushing pump 200 in the front-to-back direction can be shortened, the volume of the flushing pump 200 can be reduced, and the internal space of the flushing pump 200 can be used to accommodate the drive motor 235 in a more reasonable way, thereby effectively improving the space utilization and portability of the flushing pump 200.

[0053] Reference Figure 3 and Figure 5 As shown, it can be understood that the first connector 211 and the second connector 234 are respectively disposed facing away from each other on both sides of the housing 210. Specifically, in this embodiment, the first connector 211 is disposed on the right side of the housing 210, and the second connector 234 is disposed on the left side of the housing 210.

[0054] The first connector 211 and the second connector 234 are respectively positioned opposite to each other on both sides of the housing 210, and the first control interface 216 is positioned on the rear side of the housing 210. This allows the pipes and wires 113 connected to the control valve 220, pump body 230 and controller 310 to be located on different side walls of the housing 210, which facilitates wiring by the user and avoids tangling and knotting of the wires, effectively improving the structural rationality and assembly convenience of the flushing pump 200.

[0055] Reference Figure 6As shown, it can be understood that a handle groove 215 is provided on one side of the housing 210, and the bottom end of the handle groove 215 is inclined upward along the depth direction of the handle groove 215.

[0056] By providing a handle groove 215, the flushing pump 200 can be easily moved and transported by the user without increasing its volume, further improving its portability. In this embodiment, the handle groove 215 is located on the rear side wall of the housing 210 and above the power supply 240. The space between the power supply 240 and the controller 310 is used to accommodate the side wall of the handle groove 215, further improving the space utilization of the flushing pump 200.

[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
