Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to a visual multifunctional guide. Background Technology

[0002] Neurosurgical procedures, especially those related to cerebral hemorrhage or cerebral hematoma, require surgeons to perform the surgery under a microscope or through an endoscope. The surgery mainly uses a combination of instruments such as suction devices, flushing devices, and electrocoagulation devices.

[0003] With the development of neurosurgery from gross neurosurgery to microsurgical neurosurgery and minimally invasive neurosurgery, endoscopes have become one of the main instruments used in minimally invasive neurosurgical procedures. They mainly consist of a handheld rigid endoscope (guide), a camera unit, and a monitor. The handheld rigid endoscope is inserted into the patient's skull by the surgeon for exploration, and the images are processed by the camera unit and converted into image signals. Real-time images of the intracranial cavity are then displayed on the monitor. The surgeon performs the surgical procedure based on the images on the monitor.

[0004] Current neuroendoscopic hematoma evacuation procedures typically involve inserting a suitable cannula into the hematoma cavity, and then aspirating and stopping the hematoma within the cannula's space. During the procedure, the endoscope and suction device are inserted into the hematoma cavity through the cannula to remove the hematoma. If there is clearly active bleeding, a bipolar electrocautery device is then inserted for electrocoagulation hemostasis. For stopping active bleeding, an assistant can hold the endoscope to assist the surgeon in performing "two-handed" hemostasis under direct endoscopic visualization. The assistant holds the endoscope to expose the stump of the vessel causing active bleeding, while the surgeon holds the suction device in their left hand and the bipolar electrocautery device in their right hand to perform "two-handed" hemostasis.

[0005] However, during the procedure, there are problems such as interference between the suction device, endoscope, and bipolar electrocoagulation instruments in the working channel, as well as asynchronous operation between the two operators.

[0006] Therefore, there is an urgent need to develop a visual, multifunctional guide to solve the above-mentioned technical problems.

[0007] It should be noted that the above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0008] The aim is to solve the above-mentioned technical problems and provide a new type of visual multifunctional guide with high functional integration, high space utilization, simple structure, high reliability and easy operation.

[0009] This application relates to a visual multifunctional guide, comprising:

[0010] The main body includes the shell and the internal cavity formed by the shell;

[0011] A guide tube is connected to the main body and arranged along a first direction, and the guide tube has a guide channel communicating with the inner cavity;

[0012] A movable component is disposed within the inner cavity, the movable component comprising a base, an adjustment assembly disposed on the base, and an extension connected to the adjustment assembly;

[0013] A suction tube is disposed within the inner cavity and the guide channel, and the suction tube passes through the movable member and is fixedly connected to the movable member;

[0014] A flushing tube is disposed within the inner cavity and the guide channel, the flushing tube passing through the movable member and spaced apart from the suction tube;

[0015] An instrument channel is provided on the housing and communicates with the inner cavity and the guide channel. The instrument channel is located away from the moving member in a second direction, and the second direction is perpendicular to the first direction.

[0016] The endoscope assembly is disposed within the lumen and the guide channel;

[0017] The movable component moves within the inner cavity along the first direction and drives the suction tube to move in the first direction. The housing is provided with a blocking part that cooperates with the extension. The blocking part is located within the inner cavity and controls the opening and closing of the suction tube. The adjusting component includes a rotating part, a rotating shaft that cooperates with the rotating part, and a traction part that connects the suction tube and the rotating shaft. The rotating shaft moves along a third direction and drives the traction part to pull the free end of the suction tube to bend. The third direction is perpendicular to the first direction and the second direction. The flushing tube is bent and inserted into the movable component. The rotating part is connected to the rotating shaft. The rotation of the rotating shaft drives the rotating part to rotate. The rotation of the rotating part opens or closes the flushing tube.

[0018] When the above technical solution is adopted, the visual multifunctional guide includes a suction tube, a flushing tube, an instrument channel, and an endoscope assembly. By integrating the four instruments—suction tube, flushing tube, instrument, and endoscope—into one guide, it can not only prevent mutual interference between the instruments but also enable one person to operate the device, effectively solving the problem of asynchronous operation between two people.

[0019] The movable component moves within the inner cavity along a first direction, driving the suction tube to move in the same direction. This movement extends the suction tube beyond the guide tube, allowing suction to be applied to the lesion or area requiring treatment. The operation is simple and convenient, with controllable stroke to prevent uncontrolled extension due to excessive travel or contact with other areas due to guide movement, thus improving operational safety. The housing has a blocking part that mates with the extension. The distance between the extension and the suction tube in a second direction is controlled by whether the extension and the blocking part abut each other, thereby controlling the opening and closing of the suction tube. This convenient operation fully utilizes the structure and space of the movable component within the guide, achieving opening and closing of the suction tube solely through the movement of the movable component. The structure is simple and space-saving. A traction unit is connected to the rotating shaft. Moving the shaft in a third direction pulls the traction unit, which in turn causes the free end of the suction tube to bend. When the guide tube's position and orientation need to be fixed or restricted, it can effectively and thoroughly irrigate the lesion or designated area, improving the accuracy and expanding the irrigation range, thus increasing the convenience of the operation. It can also shorten the operation time and improve the efficiency of the surgery. The irrigation tube is bent and inserted into the moving part. The rotation of the rotating shaft drives the rotating part to rotate, thus opening and closing the irrigation tube through the rotation of the shaft. The structure is simple and easy to operate.

[0020] A movable component is installed inside the cavity of the visual multifunctional guide. The movement of the movable component along the first direction not only allows the suction tube to extend out of the guide tube, but also allows the suction tube to be opened or closed through the extension part. In addition, the movement of the rotating shaft in the third direction drives the traction part to pull the suction tube, thereby causing the free end of the suction tube to bend. At the same time, the rotating shaft can also rotate clockwise or counterclockwise. Through the rotation of the rotating shaft, the flushing tube bent inside the movable component can be opened or closed. The movable component of the visual multifunctional guide can realize four functions: movement of the suction tube, opening and closing of the suction tube, bending of the free end of the suction tube, and opening and closing of the flushing tube. It realizes four functions within a limited cavity space, with high functional integration and high space utilization. The structure is simple, and the switch is opened or closed by movement or rotation. It has high reliability and is easy to operate.

[0021] In one specific implementation, the substrate includes a first part, a second part, and a cavity formed by the first part and the second part, with the rotating part disposed within the cavity.

[0022] By adopting the above technical solution, the base is divided into a first part and a second part, which not only facilitates assembly and reduces manufacturing costs, but also allows the cavity to accommodate the rotating part, resulting in high space utilization.

[0023] In one specific implementation, the cavity is provided with a stop and a sliding shaft that cooperates with the rotating part. There is a first gap between the stop and the sliding shaft. The flushing pipe is disposed in the first gap. The rotating part is provided with a sliding groove. The sliding shaft is disposed in the sliding groove. The size of the first gap is adjusted by rotating the rotating part to drive the sliding shaft to move in the sliding groove.

[0024] With the above technical solution, the rotating part is provided with a slide groove, and the sliding shaft is located in the slide groove. By rotating the rotating part, the sliding shaft can move in the slide groove, thereby adjusting the size of the first gap. The stop part is a fixed part, and the sliding shaft is a moving part. By rotating the rotating part, the distance between the sliding shaft and the stop part can be adjusted. The position can be changed and the distance can be increased or decreased by rotating. It is not only simple to operate and easy to learn, but also has a reliable structure and high stability.

[0025] In one specific implementation, the chute is provided with a first positioning groove and a second positioning groove, the sliding shaft is located in the first positioning groove, the flushing pipe is in a closed state, the sliding shaft is located in the second positioning groove, and the flushing pipe is in an open state.

[0026] When the above technical solution is adopted, the first positioning groove and the second positioning groove are the limiting structure of the sliding shaft. When the sliding shaft is set in the first positioning groove or the second positioning groove, the sliding shaft will no longer move in the groove. This can prevent the distance between the sliding shaft and the stop from changing, affecting the on / off state of the flushing pipe, and increasing the reliability and stability of the structure.

[0027] In one specific implementation, when the flushing pipe is in the closed state, the first gap is less than or equal to the sum of the thicknesses of the two walls of the flushing pipe; when the flushing pipe is in the open state, the first gap is greater than the sum of the thicknesses of the two walls of the flushing pipe.

[0028] When the above technical solution is adopted, the opening and closing of the flushing pipe is achieved by the sum of the first gap and the thickness of the two walls of the flushing pipe. When the sliding shaft is located in the first positioning groove, the first gap is less than or equal to the sum of the thickness of the two walls of the flushing pipe, and it is in the closed state. When the sliding shaft is located in the second positioning groove, the first gap is greater than the sum of the thickness of the two walls of the flushing pipe, and it is in the open state. The operation is convenient and the structure is reliable.

[0029] In one specific implementation, the flushing pipe is bent between the rotating shaft and the sliding shaft, the flushing pipe is located between the rotating shaft and the sliding shaft in the first direction, and the flushing pipe is located on the side of the rotating shaft and the sliding shaft away from each other in the second direction.

[0030] With the above technical solution, the flushing pipe is bent inside the cavity of the moving part. The bending of the flushing pipe is achieved by the support of the rotating shaft and the sliding shaft, and the space in the first and second directions is fully utilized. This not only allows for the arrangement of the flushing pipe, but also reduces the overall space of the moving part.

[0031] In one specific implementation, the adjusting assembly further includes an elastic element sleeved on the rotating shaft and the sliding shaft, and the rotating shaft and / or the sliding shaft are provided with a groove for placing the elastic element.

[0032] With the above technical solution, elastic elements are sleeved on the rotating shaft and the sliding shaft, which can not only ensure the normal sliding of the sliding shaft, but also give the sliding shaft an elastic force, restricting both in the direction of the axis connecting the rotating shaft and the sliding shaft, preventing the sliding shaft from moving in the first or second direction, and the groove can prevent the sliding shaft from moving in the third direction, thus increasing the reliability and durability of the structure.

[0033] In one specific implementation, the rotating part consists of two parts arranged side by side along the axis of rotation, with a second gap between the two rotating parts; the number of elastic elements is two, and both elastic elements are disposed within the second gap; the flushing pipe is disposed within the second gap.

[0034] With the above technical solution, two rotating parts are provided, which can not only accommodate the flushing pipe and limit its movement to prevent structural damage caused by uneven force, but also increase the stability of the structure. At the same time, the double-layer structure can also increase the structural strength and rigidity.

[0035] In one specific implementation, the inner walls of the first and second parts are respectively provided with grooves recessed along the third direction away from the flushing pipe, and the sliding shaft is capable of moving within the grooves.

[0036] When the above technical solution is adopted, the groove provided in the inner wall can restrict the sliding shaft to move within the groove, preventing the sliding shaft from sliding arbitrarily, thereby playing a limiting role.

[0037] In one specific implementation, the edge of the groove is provided with protrusions that protrude from the inner walls of the first and second parts respectively. In the third direction, the distance between the two protrusions is less than the length of the sliding shaft, and the length of the sliding shaft is less than the distance between the two grooves.

[0038] When the above technical solution is adopted, the protrusion blocks the sliding shaft in the direction of movement, preventing the sliding shaft from moving further and leaving the groove. The distance between the two protrusions is less than the length of the sliding shaft and less than the distance between the two grooves. This allows the sliding shaft to slide normally in the groove without moving out of the groove, thus improving the stability of the fit and the reliability of the structure.

[0039] In one specific implementation, the first positioning groove and the second positioning groove are arc-shaped grooves, the radius of which is greater than the radius of the sliding shaft and less than the diameter of the sliding shaft.

[0040] When the above technical solution is adopted, the radius of the arc groove is greater than the radius of the sliding shaft and less than the diameter of the sliding shaft. This not only ensures that the sliding shaft can move smoothly into the arc groove, but also that when the sliding shaft moves into the groove, it does not need to move in the radial direction of the rotating shaft. The movement of the sliding shaft in the groove and its smooth entry and exit from the first positioning groove and the second positioning groove can be achieved simply by rotating the rotating shaft.

[0041] In one specific implementation, the body includes a handle that is located away from the instrument channel in the second direction. The side of the handle away from the instrument channel has a first channel through which the flushing tube passes and a second channel through which the endoscope assembly passes. The body also includes a third channel that is located away from the guide tube in the first direction and through which the suction tube passes.

[0042] With the above technical solution, the handle is easy for the operator to hold and use with one hand, the instrument channel is far away from the handle in the second direction, and the space reserved when holding the handle with one hand makes it easy for the other hand to operate the instrument. The first channel, the second channel and the third channel facilitate the storage and fixation of the suction tube, the flushing tube and the endoscope assembly.

[0043] In one specific implementation, the housing is provided with a sliding hole at the corresponding position of the rotating shaft, the rotating shaft moves in the first direction within the sliding hole, and the rotating shaft is provided with a first knob on the outside of the housing.

[0044] With the above technical solution, the rotating shaft is connected to the first knob and to the moving part. By moving the first knob in the sliding hole, the moving part can be moved, which increases the contact area between the operator and the hand when moving, making it easier to move. The increased contact area with the hand improves the reliability and convenience of operation, and also facilitates one-handed operation.

[0045] In one specific implementation, the housing has a second knob near the handle, the guide tube has multiple snake-like joints, and the guide channel has a traction rope connected to the snake-like joints. The second knob controls the bending of the snake-like joints by adjusting the traction rope.

[0046] When the above technical solution is adopted, the bending of the snake joint is controlled by rotating the knob to drive the winding of the traction rope, thereby controlling the bending of the free end of the guide tube, which facilitates better positioning of the lesion area.

[0047] In one specific implementation, the extension is disposed in the first direction away from the guide tube and inclined from the direction away from the suction tube toward the direction closer to the suction tube, the blocking part is adapted to the extension and the first inclined surface of the blocking part corresponds to the inclination direction of the second inclined surface of the extension.

[0048] When the above technical solution is adopted, the extension is inclined. When the extension and the blocking part press against each other, the distance between the extension and the suction tube becomes smaller and the suction tube is compressed. This makes full use of the moving distance of the moving part in the first direction and the distance change in the second direction to realize the opening and closing of the suction tube. It has high space utilization and is easy to operate. Attached Figure Description

[0069] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0070] This application provides a visual, multifunctional guide, such as... Figures 1-7As shown, the device includes a main body 1, a guide tube 2, a movable component 3, a suction tube 4, a flushing tube 5, an instrument channel 6, and an endoscope assembly 7. The main body 1 includes a housing 11 and an inner cavity 12 formed by the housing 11. The guide tube 2 is connected to the main body 1 and is arranged along the first direction X. The guide tube 2 has a guide channel 20 communicating with the inner cavity 12. The movable component 3 is located in the inner cavity 12 and includes a base 31, an adjustment component 32 on the base 31, and an extension 33 connected to the adjustment component 32. The suction tube 4 is located in the inner cavity 12 and the guide channel 20. The suction tube 4 passes through the movable component 3 and is fixedly connected to the movable component 3. The flushing tube 5 is located in the inner cavity 12 and the guide channel 20. The flushing tube 5 passes through the movable component 3 and is spaced apart from the suction tube 4. The instrument channel 6 is located on the housing 11 and communicates with the inner cavity 12 and the guide channel 20. The instrument channel 6 is located away from the movable component 3 in the second direction Y. The second direction Y is perpendicular to the first direction X. The endoscope assembly 7 is located in the inner cavity 12 and the guide channel 20. The moving part 3 moves in the inner cavity 12 along the first direction X and drives the suction tube 4 to move in the first direction X. The housing 11 is provided with a blocking part 15 that cooperates with the extension part 33. The blocking part 15 is located in the inner cavity 12 and controls the opening and closing of the suction tube 4. The adjusting assembly 32 includes a rotating part 321, a rotating shaft 322 that cooperates with the rotating part 321, and a traction part 323 that connects the suction tube 4 and the rotating shaft 322. The rotating shaft 322 moves along the third direction Z and drives the traction part 323 to pull the free end of the suction tube 4 to bend. The third direction Z is perpendicular to the first direction X and the second direction Y. The flushing tube 5 is bent and inserted in the moving part 3. The rotating part 321 is connected to the rotating shaft 322. The rotation of the rotating shaft 322 drives the rotating part 321 to rotate. The rotation of the rotating part 321 opens or closes the flushing tube 5.

[0071] The visualization multifunctional guide of this application includes a suction tube 4, an irrigation tube 5, an instrument channel 6, and an endoscope assembly 7. Integrating the suction tube 4, irrigation tube 5, instruments, and endoscope into one guide not only prevents interference between the instruments but also allows for single-person operation, effectively solving the problem of asynchronous operation between two people. The suction tube 4, irrigation tube 5, instruments, and endoscope can all extend from the free end of the guide tube 2 through the guide channel 20 to treat the lesion area, making operation convenient and highly integrated.

[0072] The movable component 3 moves within the inner cavity 12 along the first direction X, driving the suction tube 4 to move along the first direction X. This allows the suction tube 4 to extend beyond the guide tube 2, thereby suctioning the lesion or the area requiring treatment. The operation is simple and convenient, and the stroke is controllable, preventing uncontrolled extension due to excessive stroke or contact with other areas due to the movement of the guide, thus improving operational safety. The housing 11 has a blocking part 15 that cooperates with the extension 33. The distance between the extension 33 and the suction tube 4 in the second direction Y is controlled by whether the extension 33 abuts against the blocking part 15, thereby controlling the opening and closing of the suction tube 4. This is convenient and makes full use of the structure and space of the movable component 3 within the guide. The opening and closing of the suction tube 4 can be achieved solely through the movement of the movable component 3, resulting in a simple structure and space-saving design. A traction part 323 is connected to the rotating shaft 322. The rotating shaft 322 moves along the third direction Z, pulling the traction part 323, which in turn causes the free end of the suction tube 4 to bend. When the position and orientation of the guide tube 2 need to be fixed or restricted, the lesion or designated area can be effectively and thoroughly flushed, improving the accuracy of flushing and expanding the flushing range, thereby improving the convenience of the operation process. At the same time, it can also shorten the operation time and improve the efficiency of the operation. The flushing tube 5 is bent and inserted into the moving part 3. The rotation of the rotating shaft 322 drives the rotating part 321 to rotate, that is, the opening and closing of the flushing tube 5 is achieved by the rotation of the rotating shaft 322. The structure is simple and easy to operate.

[0073] A movable component 3 is installed inside the inner cavity 12 of the visual multifunctional guide. The movement of the movable component 3 along the first direction X not only allows the suction tube 4 to extend out of the guide tube 2, but also allows the suction tube 4 to be opened or closed through the extension part 33. In addition, the movement of the rotating shaft 322 in the third direction Z drives the traction part 323 to pull the suction tube 4, thereby causing the free end of the suction tube 4 to bend. At the same time, the rotating shaft 322 can also rotate clockwise or counterclockwise. Through the rotation of the rotating shaft 322, the flushing tube 5 bent inside the movable component 3 can be opened or closed. The movable component 3 of the visual multifunctional guide can realize four functions: movement of the suction tube 4, opening and closing of the suction tube 4, bending of the free end of the suction tube 4, and opening and closing of the flushing tube 5. Four functions are realized in the limited space of the inner cavity 12. The functional integration is high and the space utilization is high. The structure is simple. The opening or closing of the switch is realized by movement or rotation. The reliability is high and the operation is convenient.

[0074] like Figures 1 to 2As shown, the main body 1 includes a handle 14, which is located away from the instrument channel 6 in the second direction Y. On the side of the handle 14 away from the instrument channel 6, there is a first channel 16 for the flushing tube 5 to pass through and a second channel 17 for the endoscope assembly 7 to pass through. The main body 1 also includes a third channel 18, which is located away from the guide tube 2 in the first direction X and allows the suction tube 4 to pass through. The handle 14 is designed for easy one-handed operation. The instrument channel 6 is located away from the handle 14 in the second direction Y, providing space for the other hand to operate the instrument while holding the handle 14. The first channel 16, second channel 17, and third channel 18 facilitate the storage and fixation of the suction tube 4, flushing tube 5, and endoscope assembly 7. The opening of the instrument channel 6 faces the guide tube 2, i.e., the opening of the instrument channel 6 is inclined in the first direction X, facilitating the entry of the instrument into the guide tube 2 and its extension out of the guide channel 20. The suction tube 4 includes a first tube 41 and a corrugated tube 42. The flushing tube 5 includes a second tube 51 located within the inner cavity 12. The endoscope assembly 7 includes an endoscope and an endoscope cable 71. The first tube 41, the second tube 51, and the endoscope cable 71 are all located within the inner cavity 12. The first tube 41 and the second tube 51 are both connected by a moving part 3. The opening and closing of the first tube 41 and the second tube 51 are achieved by moving the moving part 3 and rotating the rotating part 321. The opening and closing of the tubes can be achieved simply by moving and rotating, which is convenient to operate. The short stroke of the moving and rotating parts not only reduces the space required for operation but also allows the tubes to be opened and closed with less force, saving time and effort. In addition, the tubes can be opened and closed by simple moving and rotating actions without the need for complex structural connections, resulting in a simple structure and high reliability.

[0075] like Figures 1 to 2 As shown, the housing 11 has a sliding hole 13 corresponding to the rotating shaft 322. The rotating shaft 322 moves along the first direction X within the sliding hole 13. A first knob 3221 is provided on the outside of the housing 11. The rotating shaft 322 is connected to the first knob 3221 and to the moving part 3. By moving the first knob 3221 within the sliding hole 13, the moving part 3 can be moved, increasing the contact area between the operator's hand and the moving part, making movement easier and more effortless. The increased contact area also improves the reliability and convenience of operation, and facilitates one-handed operation. The diameter of the first knob 3221 is larger than the diameter of the rotating shaft 322.

[0076] The housing 11 has a second knob (not shown) near the handle 14. The housing 11 has an inwardly recessed receiving groove 19, within which the second knob is located. This design facilitates user operation, saves space, and increases the strength of the housing 11. The guide tube 2 has multiple serpentine joints 21. A traction rope (not shown) connected to the serpentine joints 21 is located within the guide channel 20. The second knob controls the bending of the serpentine joints 21 by adjusting the traction rope. Rotating the second knob causes the traction rope to wind, controlling the bending of the serpentine joints 21 and thus the bending of the free end of the guide tube 2, facilitating better localization of the lesion area. The guide tube 2 is covered with a protective layer on the outside of the serpentine joints 21. This protective layer is made of soft or elastic material, providing protection and cushioning to the human body or lesion area when the guide tube 2 enters the lesion area. The guide tube 2 is provided with two mounting slots 22 at one end near the moving part 3. The guide tube 2 is mounted on the housing 11 through the mounting slots 22 on both sides to restrict the movement and rotation of the guide tube 2 in the first direction X, the second direction Y and the third direction Z.

[0077] like Figure 2 As shown, the extension 33 is arranged in the first direction X away from the guide tube 2 and inclined from the direction away from the suction tube 4 towards the suction tube 4. The blocking part 15 is adapted to the extension 33, and the first inclined surface 150 of the blocking part 15 corresponds to the inclination direction of the second inclined surface 332 of the extension 33. The extension 33 is inclined. When the extension 33 and the blocking part 15 press against each other, the distance between the extension 33 and the suction tube 4 becomes smaller, and the suction tube 4 is compressed. This makes full use of the moving distance of the moving member 3 in the first direction X and the distance change in the second direction Y to realize the opening and closing of the suction tube 4. The space utilization is high and the operation is convenient. In the embodiment of this application, there are two extensions 33, which are respectively arranged on both sides of the suction tube 4. There are also two blocking parts 15, which correspond to the extensions 33. The extension 33 has a protrusion 331 at the end away from the base 31 that protrudes toward the suction tube 4. When the moving member 3 moves to one side along the first direction X, the extension 33 abuts against the blocking part 15. The two protrusions 331 squeeze the bellows 42 of the suction tube 4, so that the tube of the suction tube 4 is closed. When the moving member 3 moves to the other side along the first direction X, the extension 33 moves away from the blocking part 15. The two protrusions 331 release the bellows 42 of the suction tube 4, so that the tube of the suction tube 4 is opened. Because the bellows 42 has good elasticity and compressibility, it will not be damaged after repeated squeezing and releasing, thus ensuring the reliability and safety during use.

[0078] like Figures 2 to 6As shown, the base 31 includes a first part 311, a second part 312, and a cavity 313 formed by the first part 311 and the second part 312. The rotating part 321 is disposed in the cavity 313. The base 31 is divided into the first part 311 and the second part 312, which not only facilitates assembly but also reduces manufacturing costs. At the same time, the cavity 313 can accommodate the rotating part 321, resulting in high space utilization. The first part 311 and the second part 312 are provided with a limiting part 34 on the side near the housing 11. The limiting part 34 is provided with a through hole for the traction part 323 to pass through, so as to fix and limit the traction part 323, prevent the traction part 323 from shaking in the inner cavity 12 and affecting the movement of the moving part 3 and the bending angle and bending distance of the suction tube 4. Both the first part 311 and the second part 312 are provided with a connecting hole 319 for accommodating the flushing pipe 5. Since the flushing pipe 5 is bent, the connecting hole 319 facilitates the installation of the flushing pipe 5.

[0079] like Figures 6 to 7 As shown, the cavity 313 is provided with a stop 314 and a sliding shaft 315 that cooperates with the rotating part 321. A first gap 316 exists between the stop 314 and the sliding shaft 315. The flushing pipe 5 is disposed within the first gap 316. The rotating part 321 is provided with a groove 3211, and the sliding shaft 315 is disposed within the groove 3211. Rotation of the rotating part 321 drives the sliding shaft 315 to move within the groove 3211, adjusting the size of the first gap 316. The rotating part 321 is provided with a groove 3211. 11. The sliding shaft 315 is located in the slide groove 3211. By rotating the rotating part 321, the sliding shaft 315 can move within the slide groove 3211, thereby adjusting the size of the first gap 316. The stop part 314 is a fixed part, and the sliding shaft 315 is a moving part. By rotating the rotating part 321, the distance between the sliding shaft 315 and the stop part 314 can be adjusted. The position can be changed and the distance can be increased or decreased by rotating. It is not only simple and easy to operate, but also has a reliable structure and high stability.

[0080] The inner walls 35 of the first part 311 and the second part 312 are respectively provided with a groove 37 recessed along the third direction Z direction away from the flushing pipe 5. The sliding shaft 315 can move in the groove 37. The groove 37 recessed in the inner wall 35 can restrict the sliding shaft 315 to move in the groove 37, preventing the sliding shaft 315 from sliding arbitrarily, thereby playing a limiting role. The edge of the groove 37 has protrusions 38 that protrude from the inner walls 35 of the first segment 311 and the second segment 312, respectively. In the third direction Z, the distance between the two protrusions 38 is less than the length of the sliding shaft 315, and the length of the sliding shaft 315 is less than the distance between the two grooves 37. The protrusions 38 block the sliding shaft 315 in the direction of movement, preventing the sliding shaft 315 from moving further and disengaging from the groove 37. The distance between the two protrusions 38 is less than the length of the sliding shaft 315 and less than the distance between the two grooves 37, which allows the sliding shaft 315 to slide normally within the groove 37 without causing it to move out of the groove 37, thus improving the stability of the fit and the reliability of the structure. The length of the sliding shaft 315 is its axial length. The groove 37 has a straight portion 371 on the side wall near the rotating shaft 322. The straight portion 371 corresponds to the position of the first positioning groove 3212 and the second positioning groove 3213. When the sliding shaft 315 is located in the first positioning groove 3212 and the second positioning groove 3213, the sliding shaft 315 is in the straight portion 371, which can prevent the sliding shaft 315 from moving in the direction of the line connecting the axis of the sliding shaft 315 and the axis of the rotating shaft 322, and has a good blocking and limiting effect.

[0081] like Figures 5 to 6As shown, the slide groove 3211 is provided with a first positioning groove 3212 and a second positioning groove 3213. The sliding shaft 315 is located in the first positioning groove 3212 and the flushing pipe 5 is in the closed state. The sliding shaft 315 is located in the second positioning groove 3213 and the flushing pipe 5 is in the open state. The first positioning groove 3212 and the second positioning groove 3213 are the limiting structures for the sliding shaft 315. When the sliding shaft 315 is set in the first positioning groove 3212 or the second positioning groove 3213, the sliding shaft 315 will no longer move in the slide groove 3211. This can prevent the distance between the sliding shaft 315 and the stop part 314 from changing, affecting the on / off state of the flushing pipe 5, and increasing the reliability and stability of the structure. When the flushing pipe 5 is in the closed state, the first gap 316 is less than or equal to the sum of the thicknesses of the two walls of the flushing pipe 5. When the flushing pipe 5 is in the open state, the first gap 316 is greater than the sum of the thicknesses of the two walls of the flushing pipe 5. The opening and closing of the flushing pipe 5 is achieved by the size of the first gap 316 and the sum of the thicknesses of the two walls of the flushing pipe 5. When the sliding shaft 315 is located in the first positioning groove 3212, the first gap 316 is less than or equal to the sum of the thicknesses of the two walls of the flushing pipe 5, which is the closed state. When the sliding shaft 315 is located in the second positioning groove 3213, the first gap 316 is greater than the sum of the thicknesses of the two walls of the flushing pipe 5, which is the open state. The operation is convenient and the structure is reliable.

[0082] The first positioning groove 3212 and the second positioning groove 3213 are arc-shaped grooves. The radius of the arc-shaped grooves is larger than the radius of the sliding shaft 315 but smaller than the diameter of the sliding shaft 315. This not only ensures that the sliding shaft 315 moves smoothly into the arc-shaped grooves, but also allows the sliding shaft 315 to move within the sliding groove 3211 without needing to move radially in the rotating shaft 322. The movement of the sliding shaft 315 within the sliding groove 3211 and its smooth entry and exit from the first positioning groove 3212 and the second positioning groove 3213 are achieved simply by rotating the rotating shaft 322. The rotating part 321 is fan-shaped, and the angle of rotation between the rotating shaft 322 and the sliding shaft 315 is less than or equal to 90 degrees. This allows for the opening and closing of the flushing pipe 5 with a smaller stroke, enabling the user to operate it with less movement and force, thus facilitating user operation and saving space.

[0083] like Figures 5 to 6 As shown, the flushing pipe 5 is bent between the rotating shaft 322 and the sliding shaft 315. The flushing pipe 5 is located between the rotating shaft 322 and the sliding shaft 315 in the first direction X, and in the second direction Y, it is located on the side of the rotating shaft 322 and the sliding shaft 315 away from each other. The flushing pipe 5 is bent in the cavity 313 of the moving part 3. The bending of the flushing pipe 5 is achieved by the support of the rotating shaft 322 and the sliding shaft 315, and the space in the first direction X and the second direction Y is fully utilized. This not only realizes the pipeline arrangement of the flushing pipe 5, but also reduces the overall space of the moving part 3.

[0084] like Figure 5 As shown, the adjustment assembly 32 also includes an elastic element 317 sleeved on the rotating shaft 322 and the sliding shaft 315. The rotating shaft 322 and / or the sliding shaft 315 are provided with a groove 318 for placing the elastic element 317. The elastic element 317 sleeved on the rotating shaft 322 and the sliding shaft 315 can ensure the normal sliding of the sliding shaft 315 and also provide an elastic force to the sliding shaft 315. It restricts both the rotating shaft 322 and the sliding shaft 315 in the direction of the axis connecting the axes, preventing the sliding shaft 315 from moving in the first direction X or the second direction Y. The groove 318 can prevent the sliding shaft 315 from moving in the third direction Z, increasing the reliability and durability of the structure.

[0085] like Figures 4 to 5 As shown, there are two rotating parts 321 arranged side by side along the axis of the rotating shaft 322, and there is a second gap 324 between the two rotating parts 321. There are two elastic elements 317, and both elastic elements 317 are arranged in the second gap 324. The flushing pipe 5 is arranged in the second gap 324. The two rotating parts 321 can not only accommodate the flushing pipe 5 and limit the flushing pipe 5 to prevent structural damage caused by uneven force, but also increase the stability of the structure. At the same time, the double-layer structure can also increase the structural strength and rigidity. A rotating shaft 322 is disposed within a rotating shaft hole 36. A connecting hole 3223 is provided on the rotating shaft 322. The traction part 323 passes through the connecting hole 3223 and is fixed to the rotating shaft 322 via the connecting hole 3223, facilitating the movement of the rotating shaft 322 in the third direction Z. This movement of the rotating shaft 322 in the third direction Z translates into a change in the distance of the traction part 323 to the corresponding side of the suction tube 4. The movement of the rotating shaft 322 in the third direction Z achieves the bending of the suction tube 4 at its free end. The movement distance is controllable and does not affect the rotation of the rotating shaft 322 or the operation of other components, exhibiting high integration and high space utilization. The rotating shaft 322 is provided with a connecting part 3222 that protrudes to cooperate with the rotating part 321, connecting the rotating part 321 and the rotating shaft 322 as a whole, so that when the rotating shaft 322 rotates, the rotating part 321 also rotates.
