When the flushing fluid is used up, it needs to be drawn again. The process is cumbersome, increases the workload, and the extraction process wastes a certain amount of time; (3) In order to facilitate the extraction of flushing fluid during surgery, a basin filled with flushing fluid is often placed on the operating table.

DETAILED DESCRIPTION

[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices consistent with some aspects of the present application as detailed in the appended claims.

[0033] Refer to the attached Figure 1-Figure 11 This specific embodiment provides a multi-diameter flushing device for use during neurosurgery, including a first water outlet pipe 1, a water inlet pipe 23, a regulating component and a water control part 19. The first water outlet pipe 1 and the water inlet pipe 23 are connected through the regulating component and the water control part. A plurality of lumens are arranged in the first water outlet pipe 1. The lengths of the plurality of lumens are the same as the length of the first water outlet pipe 1, that is, the water inlet and the water outlet of the lumens are respectively located at the two ends of the first water outlet pipe 1. The regulating component includes a gear adjustment control 13 and a gear adjustment portion 7. The gear adjustment control 13 is provided with a notch 17. The gear adjustment portion 7 is connected to the gear adjustment control 13. Rotating the gear adjustment portion 7 can drive the gear adjustment control 13 to rotate, so that the notch 17 can be connected with the water inlet pipe 23 and any one of the tube lumens correspondingly, so that the flushing liquid in the water inlet pipe 23 can enter the tube lumen; and the diameters of the multiple tube lumens are different. During the operation, the surgeon can rotate the gear adjustment portion 7 to drive the gear adjustment control 13 to rotate, so that the notch 17 corresponds to the water inlet of the tube lumen of the required diameter, so that the tube lumen is connected with the water inlet pipe 23. In this way, the tube mouths of different calibers can be flexibly replaced for flushing according to the actual needs during the operation, that is, it is suitable for flushing of large amounts of water under the naked eye and microsurgery.

[0034] Among them, the water control part 19 is connected between the regulating component and the water inlet pipe 23. The water control part 19 can be an integrated structure with the water inlet pipe 23, and the water control part 19 can close the water outlet of the water inlet pipe 23 to prevent the flushing liquid from flowing out when flushing is not needed.

[0035] With such a configuration, the position of the notch 17 of the gear adjustment control 13 is adjusted by the control unit to replace the nozzles of different calibers according to actual needs. It is suitable for flushing of large amounts of water under the naked eye and for microsurgery. It has a simple structure, is easy to operate, and is convenient for clinical promotion. It solves the problem that the existing flushing device cannot flexibly replace the nozzles of different calibers for flushing according to the actual needs during the operation, that is, it cannot be suitable for flushing of large amounts of water under the naked eye and for microsurgery at the same time.

[0036] In the preferred scheme of this embodiment, the gear shift control 13 includes a pancake-shaped main part 15 and a plurality of latch wings 14, the plurality of latch wings 14 are arranged on the side wall of the main part 15, and a plurality of wing grooves 12 are arranged on the inner wall of the gear shift portion 7, the number of the wing grooves 12 is the same as the number of the latch wings 14, so that the plurality of latch wings 14 can be respectively engaged with the plurality of wing grooves 12, thereby connecting the gear shift portion 7 with the main part 15, and realizing that the gear shift control 13 can be driven to rotate while the gear shift portion 7 is rotated.

[0037] It should be noted that the notch 17 is provided on the main part 15, and the gear adjustment part 7 drives the main part 15 to rotate, thereby causing the notch 17 to rotate, so that the notch 17 corresponds to the water inlet of the tube cavity of the required diameter. In addition, the end face of the main part 15 away from the water inlet pipe 23 can be fitted with the end face of the first water outlet pipe 1 close to the water inlet pipe 23, so as to close the water inlet of other tube cavities, prevent the flushing liquid from entering other tube cavities, and thus cause water to flow out of multiple tube cavities.

[0038] Among them, a plurality of cylindrical grooves 6 are arranged on the surface of one end of the first water outlet pipe 1 close to the water inlet pipe 23, and the plurality of cylindrical grooves 6 and the plurality of tube cavities are arranged at intervals. Specifically, the plurality of cylindrical grooves 6 are respectively distributed between two adjacent tube cavities, and in the cross section, the perpendicular bisector of the line connecting the centers of the two adjacent tube cavities is the longitudinal center line of the cylindrical grooves 6 between the two tube cavities, that is, the longitudinal center line of each cylindrical groove 6 is perpendicular to the line connecting the centers of the two adjacent tube cavities and is located in the middle of the line.

[0039] Here, if Figure 2 As shown, the first water outlet pipe 1 can be provided with three lumens, namely the first lumen 2, the second lumen 3 and the third lumen 4, whose diameters can be 1 mm, 2 mm and 4 mm respectively, to meet the requirements of flushing water volume and water column size under different surgical fields. Moreover, in the cross section, the angles between the centers of the three lumens and the center of the first water outlet pipe 1 are 120 degrees respectively, so that each lumen is relatively evenly distributed in the first water outlet pipe 1.

[0040] And, if Figure 2 As shown, three cylindrical grooves 6 are provided on the surface of one end of the first water outlet pipe 1 close to the water inlet pipe 23, and the three cylindrical grooves 6 are respectively arranged at intervals from the three tube cavities. As can be seen from the above, each cylindrical groove 6 is respectively located between two adjacent tube cavities, that is, the angle between the extension line of the longitudinal midline of the three cylindrical grooves 6 and the line after the intersection with the center of the first water outlet pipe 1 is 120 degrees, thus ensuring that the distance between each cylindrical groove 6 is equal.

[0041] In this embodiment, three locking wings 14 may be provided on the side wall of the main part 15, and three wing grooves 12 may be provided on the inner wall of the gear-adjusting part 7. And the notch 17 may be in a 120-degree fan shape so as to be compatible with the three lumens.

[0042] Furthermore, if Figure 8 As shown, a plurality of cylindrical convex buckles 16 are arranged on the end surface of the main component 15 away from the water inlet pipe 23, and the plurality of cylindrical convex buckles 16 correspond to the plurality of cylindrical grooves 6 respectively, and the cylindrical convex buckles 16 can be embedded in the cylindrical grooves 6. When the cylindrical convex buckles 16 are embedded in the cylindrical grooves 6, the main component 15 fits with the end surface of the first water outlet pipe 1 close to the water inlet pipe 23, and the notch 17 is connected with one of the tube lumens of the first water outlet pipe 1 to realize the conduction of the tube lumens, and the main component 15 can also close the water inlet of the other tube lumens.

[0043] Preferably, the main component 15 is connected to the water control part 19 through the first elastic component, and the main component 15 is driven to rotate while the gear shifting part 7 is rotated. At this time, the main component 15 and the end face of the first water outlet pipe 1 close to the water control part 19 are relatively rotated and displaced. When the cylindrical convex buckle 16 slides out of the cylindrical groove 6, the main component 15 and the end face of the first water outlet pipe 1 close to the water control part 19 are relatively axially displaced. Here, the length of the axial displacement is the thickness of the cylindrical convex buckle 16, and the first elastic component is compressed by the main component 15, that is, the first elastic component is squeezed in the direction of the water control part 19; when the cylindrical convex buckle 16 slides into another cylindrical groove 6 during the rotation process, the main component 15 and the end face of the first water outlet pipe 1 close to the water control part 19 are again fitted, and the extrusion force of the first elastic component is reduced, that is, the first elastic component recovers its deformation, thereby pushing the cylindrical convex buckle 16 to completely fit into the cylindrical groove 6. At this time, the notch 17 of the main component 15 has corresponded to a tube cavity of another caliber, thereby completing the switching of tube cavities of different calibers.

[0044] The first elastic member may be a first spring ring 18 , and the diameter of the first spring ring 18 may be equal to the diameter of the main member 15 .

[0045] In order to allow the cylindrical protrusion 16 to slide out of the cylindrical groove 6 without restricting the axial displacement of the main component 15 , the length of the wing groove 12 is greater than or equal to the sum of the length of the wing 14 and the thickness of the cylindrical protrusion 16 .

[0046] In this embodiment, Figure 5 and Figure 6 As shown, a fourth lumen 9 is provided at the center of the gear-adjusting part 7, a first thread 5 is provided outside the end of the first water outlet pipe 1 close to the water inlet pipe 23, a first thread groove 10 is provided at the end of the fourth lumen 9 close to the first water outlet pipe 1, and the end of the first water outlet pipe 1 close to the water inlet pipe 23 extends into the fourth lumen 9, and the first thread 5 is embedded in the first thread groove 10, so that the first water outlet pipe 1 is connected to the gear-adjusting part 7. The first thread 5 and the first thread groove 10 can rotate relatively, so that the first water outlet pipe 1 will not hinder the rotation of the gear-adjusting part 7.

[0047] The threads of the first thread 5 are arranged in parallel rather than spiral, and the first thread groove 10 matches the first thread 5 and is also parallel. In this way, the first water outlet pipe 1 will not be separated from the gear adjustment part 7 due to the rotation of the gear adjustment part 7.

[0048] In this embodiment, the water control unit 19 includes a water control unit body 21 and a button 22. One end of the water control unit body 21 is connected to the water inlet pipe 23, and the other end is connected to the gear adjustment unit 7. Figure 8 and Fig. 9 As shown, a fifth lumen 26 is provided in the water control part body 21, and the fifth lumen 26 is connected to the water inlet pipe 23 so that the flushing liquid can enter the water control part 19. A button groove 27 is provided in the center of the water control part body 21, and the button groove 27 is connected to the fifth lumen 26. The button 22 is located in the button groove 27. Fig.11 As shown, the bottom end of the button 22 is connected to the bottom of the button groove 27 through the second elastic member, and a through opening 29 is provided at the end of the button 22 away from the second elastic member. The axis of the through opening 29 can be parallel to the axis of the fifth lumen 26, and by pressing the button 22, the through opening 29 can be connected to the fifth lumen 26, so that the flushing liquid can flow from the through opening 29 into the notch 17.

[0049] When the second elastic member is in a naturally relaxed state, that is, not compressed, the button 22 closes the fifth lumen 26, and the opening 29 is located on the side of the fifth lumen 26 away from the second elastic member. At this time, the end of the button 22 away from the second elastic member protrudes from the water control body 21 for easy pressing.

[0050] When the button 22 is pressed, the second elastic member is compressed, and the opening 29 is connected to the fifth tube cavity 26 to allow water to flow through. The greater the force of pressing the button 22, the larger the area of ​​the opening 29 connected to the fifth tube cavity 26, and the greater the water flow, thereby achieving the purpose of controlling the water flow through the button 22.

[0051] Here, the diameter of the through-port 29 is the same as the diameter of the fifth lumen 26 so that the water flow rate through the through-port 29 can reach the maximum.

[0052] It should be noted that the opening of the button groove 27 is arranged on the outer surface of the side wall of the water control part body 21 , and the water control part 19 can be rotated to change the opening of the button groove 27 to the side convenient for thumb pressing.

[0053] like Figure 8 and Fig. 9As shown, the water control part 19 also includes a second water outlet pipe 24, which is arranged at one end of the water control part body 21 close to the first water outlet pipe 1, and a second thread 25 is arranged on the second water outlet pipe 24, and a second thread groove 11 is arranged on the side wall of one end of the fourth tube cavity 9 close to the water inlet pipe 23, the second water outlet pipe 24 is located in the fourth tube cavity 9, and the second thread 25 is embedded in the second thread groove 11 and engaged with the second thread groove 11, thereby realizing the connection between the gear adjustment part 7 and the water control part 19.

[0054] Here, the inner diameter of the second water outlet pipe 24 is the same as the diameter of the fifth tube cavity 26 , and the fifth tube cavity 26 is equivalent to the continuation of the second water outlet pipe 24 .

[0055] It should be noted that the second thread 25 is parallel rather than threaded, that is, the threads of the second thread 25 are parallel; the second thread groove 11 is also parallel, so that the second water outlet pipe 24 will not be separated from the gear adjustment part 7 due to the rotation of the gear adjustment part 7.

[0056] Among them, Figure 8 and Fig. 9 As shown, one end of the first spring ring 18 is fixed to the main part 15, and the other end is fixed to the wall of the second water outlet pipe 24. In this way, the second water outlet pipe 24 becomes the force fulcrum of the gear shift control 13 and the first spring ring 18. In addition, the length of the second water outlet pipe 24 is slightly shorter than the distance from the end of the main part 15 close to the water inlet pipe 23 to the water control part body 21, so that there is space between the main part 15 and the second water outlet pipe 24 for installing the first spring ring 18.

[0057] In this embodiment, Figure 1 As shown, the gear-adjusting part 7 and the water control part 19 are connected to each other and can be generally olive-shaped, and the outer surface of the gear-adjusting part 7 is evenly provided with a plurality of longitudinal first grooves 8 to facilitate the rotation of the gear-adjusting part 7. The outer surface of the water control part 19 is provided with a plurality of longitudinal second grooves 20 to help the operator to have a good grip on the water control part 19.

[0058] Furthermore, in order to facilitate adjustment to the required caliber of the tube cavity, marks 35 are respectively provided on the outer surface of the first water outlet pipe 1 corresponding to the first tube cavity 2, the second tube cavity 3 and the third tube cavity 4, and the marks 35 are respectively "S", "M" and "L", and are provided close to the water inlet pipe 23. Among them, "S", "M" and "L" respectively represent "small", "medium" and "large", that is, they represent the first tube cavity 2, the second tube cavity 3 and the third tube cavity 4 respectively; in addition, a mark 34 "▲" is provided on the outer surface of the end of the adjustment part 7 close to the first water outlet pipe 1, and the mark 34 is provided corresponding to the notch 17. For example, when "▲" points to "S", it means that the notch 17 is facing the tube cavity with the smallest caliber, that is, the notch 17 is facing the first tube cavity 2.

[0059] In order to solve the problem that the water outlet ends of the existing syringes with hose needles and elastically drawable water balls are straight and are extremely difficult to flush deep surgical fields, the first water outlet pipe 1 is configured to be "J"-shaped, that is, one end of the first water outlet pipe 1 away from the water inlet pipe 23 is bent relative to the first water outlet pipe 1, so that the water outlet end of the first water outlet pipe 1 forms an elbow, so that the first water outlet pipe 1 can extend into the deep surgical field at a certain angle without hindering the operator.

[0060] In some embodiments, the multi-diameter flushing device is connected to the infusion bag 31 through the infusion tube 30, a third thread is provided on the outer wall of the water inlet of the water inlet pipe 23, and a third thread groove is provided on the inner wall of the infusion tube 30, where the third thread and the third thread groove are spiral, and the water inlet pipe 23 and the infusion tube 30 are connected by twisting. A speed limiter 32 is provided on the infusion tube 30, and a three-way valve 33 is also connected to connect more pipes to receive different flushing fluids, such as water containing or not containing heparin, water containing antibiotics, etc. The flushing fluid flows out of the infusion bag 31 and is transported to the flushing device through the infusion tube 30.

[0061] The infusion tube 30, the infusion bag 31, the speed limiting device 32, and the three-way valve 33 are all existing devices.

[0062] The first water outlet pipe 1, the gear adjustment part 7, the gear adjustment control part 13, and the water control part 19 can be made of plastic or metal.

[0063] The operating instructions when using this flushing device are as follows:

[0064] After routine preoperative disinfection and draping, the infusion bag 31 filled with flushing fluid is hung high, and the infusion tube 30 and the three-way valve 33 are connected. The other end of the infusion tube 30 is then connected to the water inlet pipe 23 of the water control part 19 of the device by docking and screwing. Another infusion tube and infusion bag are connected to the other opening of the three-way valve 33 according to actual needs. If this opening is not needed, the existing heparin cap can be screwed on to seal it.

[0065] The button 22 of the water control part 19 is turned to the side which is convenient for the thumb to press.

[0066] According to the requirements of flushing water volume and water column size during the operation, rotate the gear adjustment part 7 to drive the gap 17 of the gear adjustment control 13 to the tube cavity of corresponding caliber in the first water outlet pipe 1, that is, rotate the "▲" of the gear adjustment part 7 to align to "S", "M" or "L".
