Abstract
Description
Technical Field
[0001] This utility model relates to the field of laparoscopic irrigation technology, specifically to a simple laparoscopic irrigation device. Background Technology
[0002] The simple laparoscopic irrigation device can quickly and accurately irrigate when bleeding occurs during laparoscopic surgery, effectively removing accumulated blood, maintaining a clear field of vision, and helping the surgery to proceed smoothly.
[0003] Traditional simple laparoscopic irrigation devices cannot heat the irrigation fluid to a suitable temperature for the human body when rinsing accumulated blood. Since the human body is extremely sensitive to temperature, if the temperature of the irrigation fluid is too low, it will directly stimulate the patient's body, causing stress responses such as chills and vasoconstriction, thereby increasing the patient's pain. Therefore, a simple laparoscopic irrigation device is proposed. Utility Model Content

[0024] like Figure 1-5 As shown, a simple laparoscopic irrigation device includes an irrigation tube 1, and a heating component 2 for increasing the temperature of the irrigation fluid is provided outside the irrigation tube 1, such as... Figure 1 , 2 As shown in Figure 4, specifically, the heating component 2 includes a heat-insulating pipe 201. The heat-insulating pipe 201 is fixedly installed on the outside of the flushing pipe 1. An inlet pipe 202 is fixedly installed on the left side wall of the heat-insulating pipe 201, and an outlet pipe 203 is fixedly installed on the right side wall of the heat-insulating pipe 201. Several transversely equidistant diversion rings 204 are fixedly installed inside the heat-insulating pipe 201. Each diversion ring 204 has a circular hole 205 on its side wall, and every two adjacent circular holes 205 are staggered.
[0025] More specifically, a constant-temperature liquid can be injected into the interior of the insulation tube 201 through the inlet pipe 202, and the constant-temperature liquid inside the insulation tube 201 can be discharged through the outlet pipe 203. The diversion ring 204 can divide the interior space of the insulation tube 201 into several areas, thereby increasing the flow time of the constant-temperature liquid inside the insulation tube 201 and effectively using the constant-temperature liquid to heat the rinsing fluid.
[0026] The output end of the flushing tube 1 is equipped with a control valve assembly 3 for controlling the discharge of flushing fluid, and the output end of the control valve assembly 3 is equipped with a nut 4 for connecting the endoscope. Figure 1-3 As shown, specifically, the control valve assembly 3 includes a connecting pipe 301, the output end of the flushing pipe 1 is fixedly connected to the connecting pipe 301, the output end of the connecting pipe 301 is fixedly connected to a nut 4, an mounting block 302 is fixedly installed on the side wall of the connecting pipe 301, a flow baffle 303 is provided inside the connecting pipe 301, a handwheel 304 for driving the flow baffle 303 to rotate is movably installed on the top of the mounting block 302, an arc-shaped groove 305 is opened on the top of the mounting block 302, a limit rod 306 is movably installed inside the arc-shaped groove 305, the limit rod 306 is fixedly connected to the handwheel 304, two magnetic blocks 307 are fixedly installed on the top of the mounting block 302, the two magnetic blocks 307 are respectively located at both ends of the arc-shaped groove 305, and magnetic blocks 308 are respectively embedded on the two side walls of the limit rod 306, the magnetic blocks 308 and the magnetic blocks 307 attract each other.
[0027] More specifically, by manually rotating the handwheel 304, the handwheel 304 drives the baffle plate 303 to rotate synchronously, and the rotation of the handwheel 304 causes the limiting rod 306 to slide inside the arc-shaped groove 305. Through the cooperation of the limiting rod 306 and the arc-shaped groove 305, the rotation range of the handwheel 304 is limited to ninety degrees. By controlling the rotation angle of the handwheel 304, the baffle plate 303 can be used to block or not block the water flow inside the connecting pipe 301. When the limiting rod 306 slides to both ends inside the arc-shaped groove 305, each magnetic block 1 307 is attracted to magnetic block 2 308, thereby positioning the handwheel 304 at the current rotation angle.
[0028] The inlet end of the flushing pipe 1 is equipped with an anti-backflow component 5 to prevent the flushing fluid from flowing back, such as... Figure 1 , 2 As shown in Figures 4 and 5, specifically, the anti-backflow component 5 includes a connecting pipe 501. The input end of the flushing pipe 1 is fixedly connected to the connecting pipe 501. Two connecting blocks 502 are fixedly installed on the inner side wall of the connecting pipe 501. A rotating shaft 503 is movably installed between the two connecting blocks 502. A bending block 504 is fixedly installed on the side wall of the rotating shaft 503. A sealing plate 505 is fixedly installed on the side wall of the bending block 504.
[0029] More specifically, when the flushing fluid enters the interior of the connecting pipe 501 from the input end, the flushing fluid will impact the sealing plate 505. The sealing plate 505 will then drive the bending block 504 and the rotating shaft 503 to rotate at a certain angle, so that the flushing fluid can smoothly pass through the connecting pipe 501 and enter the interior of the flushing pipe 1. If the flushing fluid flows back, it will be prevented from flowing back by the blocking of the sealing plate 505.
[0030] In summary: First, the flushing tube 1 is connected to the endoscope via nut 4. Then, a constant-temperature liquid is injected into the heating assembly 2. Subsequently, an appropriate amount of flushing fluid is injected into the flushing tube 1 via the anti-backflow assembly 5. At this time, the control valve assembly 3 is in a closed state. The anti-backflow assembly 5 can prevent the flushing fluid entering the flushing tube 1 from flowing back, so that an appropriate amount of flushing fluid is placed inside the flushing tube 1 for subsequent use. At the same time, the constant-temperature liquid inside the heating assembly 2 can help raise the temperature of the flushing fluid inside the flushing tube 1, raising the temperature of the flushing fluid to a suitable temperature for the human body. If medical staff need to flush out accumulated blood, they can open the control valve assembly 3 by adjusting it, allowing the flushing fluid placed inside the flushing tube 1 and heated to enter the endoscope through the control valve assembly 3 for the flushing procedure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
