Description

[0003] Irrigation and suction devices mainly use a single-lumen tube to perform irrigation and suction through a common lumen. Sharing the same lumen for suction and irrigation also causes the "dirty" fluid just sucked back to flow back into the patient's body, which makes it more difficult to explore the bleeding site.

[0004] To this end, the existing technology proposes to use independent flushing pipes and suction pipes, and independently control the conduction of the flushing pipe through the flushing switch, and can cooperate with the flushing spring to control the flushing pipe to remain in the disconnected state; independently control the conduction of the suction pipe through the suction switch, and can cooperate with the suction spring to control the suction pipe to remain in the disconnected state.

[0005] However, in actual application, it was found that when the flushing switch controls the flushing pipeline to be turned on, the shaking of the flushing spring can easily cause the suction pipeline to be opened. Correspondingly, when the suction switch controls the suction pipeline to be turned on, the shaking of the suction spring can easily cause the flushing pipeline to be opened. Utility Model Content

[0051] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. In addition, it should be noted that for the convenience of description, only the parts related to the present utility model rather than all the structures are shown in the drawings.

[0052] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0053] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above the", and "on the" of the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below the", and "under the" of the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is lower than that of the second feature.

[0054] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinguishing in description and have no special meaning.

[0055] In an embodiment of the present utility model, Figures 1 to 14 the X direction is the first direction, the Y direction is the second direction, and the Z direction is the axial direction of the pipe joint. The X direction, Y direction, and Z direction are perpendicular to each other pairwise. Among them, both the X direction and the Y direction are the radial directions of the pipe.

[0056] Embodiment 1

[0057] An embodiment of the present utility model provides a flushing and suction device, which can realize independent control of the flushing pipe and the suction pipe respectively, and has high control accuracy.

[0058] As Figures 1 to 3 shown, the flushing and suction device includes two pipes 1, a partition structure 2, and a on-off control component 3. Among them, the two pipes 1 are arranged side by side in the first direction. The partition structure 2 includes a partition plate 21, and the partition plate 21 is located between the two pipes 1. The on-off control component 3 corresponds to the pipe 1 one by one and is on the same side of the partition plate 21 as the corresponding pipe 1. The on-off control component 3 is used to control the on-off of the corresponding pipe 1.

[0059] For convenience of description, the two pipes 1 are respectively denoted as a flushing pipe 1b and a suction pipe 1a. The flushing pipe 1b and the suction pipe 1a are arranged side by side in the first direction. The partition plate 21 is arranged in the first direction between the two flushing pipes 1b and the suction pipe 1a. The partition plate 21 is used to separate the flushing pipe 1b and the suction pipe 1a, and the on-off control component 3 for controlling the on-off of the flushing pipe 1b and the on-off control component 3 for controlling the on-off of the suction pipe 1a are separated by the partition plate 21. When the on-off of the corresponding pipe 1 is independently controlled by any on-off control component 3, the on-off control component 3 will not affect the on-off of the other pipe 1, which can greatly improve the accuracy of the on-off control of the pipe 1.

[0060] Furthermore, as Figures 1 to 3As shown, the separation structure 2 further includes a support base 22 corresponding to and connected to the partition plate 21 for each pipeline 1 to support the corresponding pipeline 1. The on-off control assembly 3 includes an on-off switch 31 and an elastic reset member 32. One end of the on-off switch 31 has an operation part 311, and the other end has a pressing part 312. The on-off switch 31 can rotate around a preset axis; the preset axis is located between the operation part 311 and the pressing part 312 along the extension direction of the on-off switch 31, so that when the operation part 311 is pressed, the pressing part 312 is lifted off the support base 22 to conduct the pipeline 1; the elastic reset member 32 is used to make the pressing part 312 have a movement tendency to press against the support base 22 to cut off the pipeline 1.

[0061] When the flushing and suction device is not in use, the elastic reset member 32 applies a force to the pressing part 312, and the pressing part 312 presses against the support base 22 to cut off the pipeline 1.

[0062] Press the operation part 311, and the on-off switch 31 will rotate around the preset axis, so that the pressing part 312 overcomes the resistance of the elastic reset member 32 and is lifted off the support base 22 to conduct the pipeline 1; during this process, the elastic reset member 32 accumulates elastic reset force. When the external force applied to the operation part 311 is withdrawn, the pressing part 312 is reset under the action of the elastic reset member 32 to cut off the pipeline 1.

[0063] Exemplarily, both the flushing pipeline 1b and the suction pipeline 1a are flexible hoses, so that the pressing part 312 can press the pipeline 1 to deform and be cut off, and the pipeline 1 automatically resumes deformation and is conducted when the pressing part 312 is lifted off the support base 22.

[0064] In this embodiment, the flushing and suction device further includes a flushing and suction housing. A rotating shaft 51 is arranged in the flushing and suction housing. Both on-off switches 31 are rotatably sleeved outside the rotating shaft 51, and the central axis of the rotating shaft 51 is the above-mentioned preset axis. Both ends of the rotating shaft 51 are connected to the flushing and suction housing, and the two on-off switches 31 are supported by the rotating shaft 51. The two on-off switches 31 share one rotating shaft 51, which simplifies the structure of the flushing and suction device.

[0065] Exemplarily, two rotating convex parts are provided on the flushing and suction housing, and both ends of the rotating shaft 51 are respectively rotatably inserted into the two rotating convex parts to improve the rotation smoothness of the on-off switch 31.

[0066] In this embodiment, as Figure 1As shown, the on-off switch 31 is provided with a guiding hole 313. The guiding hole 313 is an arc-shaped hole centered on a preset axis. The flushing and suction housing is provided with a guiding member 52. Axial ends of the guiding member 52 penetrate through the two guiding holes 313 and are connected to the flushing and suction housing. The guiding member 52 and the guiding holes 313 are in circumferential sliding fit around the preset axis. During the rotation of the on-off switch 31 around the preset axis, the guiding member 52 and the guiding holes 313 are in circumferential sliding fit around the preset axis to guide the rotation of the on-off switch 31.

[0067] In this embodiment, the elastic reset member 32 is a torsion spring 32b. The separating structure 2 further includes a reset mounting portion 25 and a reset limiting portion 27 that are both connected to the separating plate 21 and correspond to the pipelines 1 one by one. The reset mounting portion 25 penetrates through the torsion spring 32b, and one end of the torsion spring 32b is press-connected to the side of the pressing portion 312 facing away from the pipeline 1; the reset limiting portion 27 is press-connected to the other end of the torsion spring 32b.

[0068] It should be noted that the two on-off control assemblies 3 can adopt two independent torsion springs 32b or a double torsion spring. Exemplarily, the two on-off control assemblies 3 adopt a double torsion spring.

[0069] Specifically, the two reset mounting portions 25 are integrated into a reset mounting column. The reset mounting column is rotatably arranged through the separating plate 21 along a first direction around its own axis, and two ends of the reset mounting column are rotatably connected to the flushing and suction housing around its own axis.

[0070] Further, as Figures 1 to 3 shown, the separating structure 2 further includes pipeline passing portions 26 that are both connected to the separating plate 21 and correspond to the pipelines 1 one by one. The pipeline passing portions 26 and the separating plate 21 enclose a passing hole 23, and the pipeline 1 is arranged to pass through the passing hole 23 in an interference fit manner.

[0071] Passing the pipeline 1 through the passing hole 23 in an interference fit manner can play a role in fixing the pipeline 1, facilitating the control of the on-off of the pipeline 1 through the cooperation of the pressing portion 312 and the elastic reset member 32, and preventing the pipeline 1 from shaking and affecting the accuracy of the on-off control of the pipeline 1.

[0072] Further, the separating structure 2 is an integrally formed structural member, which has a simple structure, is easy to form, reduces the number of parts, reduces costs, and is beneficial to the miniaturization of the flushing and suction device.

[0073] Further, as Figure 2 and Figure 3 shown, the support base 22, the reset mounting portion 25, and the reset limiting portion 27 are arranged in sequence along the extending direction of the pipeline 1. The support base 22 has an inclined surface for supporting the pipeline 1. The inclined surface is parallel to the first direction and faces the side where the reset mounting portion 25 is located.

[0074] With such a setting, it is beneficial for the inclined surface to support the pipeline 1 and cooperate with the extrusion part 312 to control the on-off of the pipeline 1.

[0075] Further, as Figure 3 and Figure 4 shown, the partition structure 2 is arranged inside the flushing and suction housing. First positioning members 24 are arranged on both sides of the partition structure 2 in the first direction. Second positioning members 53 corresponding to the first positioning members 24 one by one are arranged on the inner wall of the flushing and suction housing. The first positioning members 24 and the second positioning members 53 are inserted and arranged along the first direction and are in contact with each other along the first direction; two limiting and supporting structures 54 are arranged on the inner wall of the flushing and suction housing, and the partition structure 2 is clamped between the two limiting and supporting structures 54 in the second direction.

[0076] Specifically, the flushing and suction housing includes two half-shells 5 with opposite openings and distributed along the first direction. The two half-shells 5 are connected to form an installation chamber, and the partition structure 2 is arranged in the installation chamber.

[0077] The two half-shells 5 are distributed along the first direction. Two first positioning members 24 are arranged on each of the two sides of the partition structure 2 in the first direction at intervals along the axial direction of the pipeline 1. The first positioning members 24 are convex positioning holes opened on the two side surfaces of the partition structure 2 in the first direction. The second positioning members 53 are convex positioning columns arranged on the inner wall of the half-shell 5. The positioning columns and the positioning holes are inserted and matched along the first direction to limit the partition structure 2 radially along the positioning holes.

[0078] The first positioning members 24 and the second positioning members 53 are in contact with each other along the first direction. After connecting the two half-shells 5, the partition structure 2 is clamped between the two half-shells 5. Without adding a new structure for fixing the partition structure 2, the partition structure 2 can be prevented from shaking, and the stability of the partition structure 2 is improved.

[0079] In this embodiment, one limiting and supporting structure 54 is arranged on the inner wall of each half-shell 5. Each limiting and supporting structure 54 includes two limiting units 541 arranged at intervals along the second direction. The two ends of the partition structure 2 in the first direction are respectively clamped between the two limiting units 541. The two limiting units 541 are arranged at intervals along the second direction to support the partition structure 2 by using the limiting and supporting structure 54 to prevent the second positioning member 53 from separating from the half-shell 5. Moreover, a space for passing through the pipeline 1 is formed among the four limiting units 541 of the two limiting and supporting structures 54, so that the limiting and supporting structure 54 will not affect the passing through of the pipeline 1.

[0080] Exemplarily, the second positioning member 53, the limiting and supporting structure 54 and the corresponding half-shell 5 are all integrally formed structural members. With such a setting, the processing can be simplified and the cost can be reduced.

[0081] Further, asFigure 1 and Figure 5 As shown in Figure 5 , one of the two on-off switches 31 is a flushing on-off switch 31b, and the other is a suction on-off switch 31a. The flushing and suction device further includes a suction speed control switch 6 rotatably mounted on the flushing and suction housing; one end of the suction speed control switch 6 is located outside the flushing and suction housing, and the other end is located inside the flushing and suction housing and is provided with a spiral speed control surface 62 at this end. The spiral speed control surface 62 spirally extends along the circumferential direction of the suction speed control switch 6. One end of the operation part 311 of the suction on-off switch 31a is provided with a speed control part 314, and the speed control part 314 axially abuts against the spiral speed control surface 62 along the suction speed control switch 6.

[0082] During the process of rotating the suction speed control switch 6, different positions of the spiral speed control surface 62 abut against the speed control part 314. The spiral speed control surface 62 pushes the speed control part 314, causing the suction on-off switch 31a to rotate around a preset axis, so that the extrusion degree of the extrusion part 312 on the suction pipe 1a is different, that is, the opening degree of the suction pipe 1a is adjusted.

[0083] Furthermore, as Figure 1 and Figure 6 shown, a speed control scale 61 is provided at one end of the suction speed control switch 6 located outside the flushing and suction housing. By setting the speed control scale 61, it is convenient for the user to accurately adjust the opening degree of the pipe 1 according to the speed control scale 61.

[0084] In this embodiment, the suction speed control switch 6 has an inner end and an outer end axially opposite to each other. The inner end is located inside the flushing and suction housing, and the outer end is located outside the flushing and suction housing. The speed control scale 61 is set on the end face of the outer end, and a rotation mark is also provided on the end face of the outer end for marking the rotation direction of the opening degree of the suction pipe 1a from large to small. With such a setting, it is convenient for the user to accurately select the rotation direction of the suction speed control switch 6 according to the needs. In other embodiments, the rotation mark can also be for marking the rotation direction of the opening degree of the suction pipe 1a from small to large.

[0085] Furthermore, as Figure 1 and Figure 5 shown, a fully open abutting surface 63 and a cut-off abutting surface 64 are provided at the inner end of the flushing and suction housing. Both the fully open abutting surface 63 and the cut-off abutting surface 64 are perpendicular to the axis of the suction speed control switch 6. The fully open abutting surface 63, the spiral speed control surface 62, and the cut-off abutting surface 64 are sequentially arranged along the circumferential direction of the suction speed control switch 6, and the fully open abutting surface 63 is connected to one end of the speed control spiral surface close to the outer end.

[0086] When the speed control part 314 axially abuts against the fully open abutting surface 63 along the suction speed control switch 6, the opening degree of the suction pipe 1a is the largest; when the speed control part 314 axially abuts against the cut-off abutting surface 64 along the suction speed control switch 6, the opening degree of the suction pipe 1a is the smallest.

[0087] In order to facilitate the rotation of the suction speed control switch 6, both ends of the spiral speed control surface 62 are smoothly and transitionally connected to the fully open contact surface 63 and the cut-off contact surface 64 respectively, so that the opening degree of the suction pipeline la changes continuously and smoothly.

[0088] When it is necessary to keep the suction pipeline la at a certain opening degree, after rotating the suction speed control switch 6 to the corresponding speed control scale 61, there is no need to manually operate the on-off switch 31, and the suction pipeline la can be kept at the current opening degree. At this time, it is impossible to further reduce the opening degree of the suction pipeline la by operating the suction on-off switch 31a, but the opening degree of the suction pipeline la can be increased by operating the suction on-off switch 31a.

[0089] Furthermore, as Figure 2 、 Figure 4 、 Figures 7 to 9 shown, the embodiment of the present utility model also provides a pipeline fixing structure. The flushing and suction device further includes the pipeline fixing structure 4, which is used to limit the two pipelines 1 simultaneously along the axial direction, the first direction and the second direction of the pipeline 1, so as to fix the pipeline 1 to the flushing and suction housing and prevent the pipeline 1 from shaking.

[0090] Specifically, the pipeline fixing structure 4 includes pipeline joints 41, first limit members 42 and second limit members 43. Among them, there are two pipeline joints 41, and the two pipeline joints 41 are arranged side by side along the first direction. The two pipeline joints 41 are arranged in one-to-one correspondence with the two pipelines 1. Each pipeline 1 includes two sub-pipelines 11, and the two sub-pipelines 11 are respectively connected to both ends of the corresponding pipeline joint 41.

[0091] There are two first limit members 42. Any pipeline joint 41 is fixed to the two first limit members 42, and the two second limit members 43 are both clamped between the two first limit members 42 along the axial direction of the pipeline joint 41.

[0092] The second limit member 43 is connected to the flushing and suction housing. There are two second limit members 43 and they are arranged in one-to-one correspondence with the two pipeline joints 41. The second limit member 43 includes a first limit portion 431 and two second limit portions 432 arranged at intervals along the second direction. The pipeline joint 41 is clamped between the two first limit portions 431 of the corresponding second limit member 43 along the second direction, and the two pipeline joints 41 are clamped between the first limit portions 431 of the two second limit members 43 along the first direction.

[0093] The second limiting member 43 is axially clamped between two first limiting members 42 along the axis of the pipeline 1 to limit the pipeline joint 41 axially along the pipeline 1; the two pipeline joints 41 are clamped between the first limiting portions 431 of two second limiting members 43 along the first direction to limit the pipeline joint 41 along the first direction; the pipeline joint 41 is clamped between the two first limiting portions 431 of the corresponding second limiting member 43 along the second direction to limit the pipeline joint 41 along the second direction.

[0094] The flushing pipeline 1b and the suction pipeline 1a share a pipeline fixing structure 4. This pipeline fixing structure 4 is relatively simple, with a small number of components, and there is no need to use connection structures such as fasteners. It is only necessary to limit the pipeline joint 41 from the first direction, the second direction and the axis of the pipeline 1, that is, the pipeline 1 connected to the pipeline joint 41 can be limited. The installation method is simple, the disassembly and assembly are convenient and fast, the structure is simple, and the occupied space is small.

[0095] Clamping the second limiting member 43 axially between two first limiting members 42 along the axis of the pipeline 1 can greatly increase the axial pulling force of the pipeline 1, thereby effectively preventing the axial pulling and dragging phenomenon of the pipeline 1.

[0096] In this embodiment, a clamping groove is provided on any second limiting member 43, and the opening of the clamping groove faces another second limiting member 43; the bottom wall of the clamping groove forms the first limiting portion 431, and each of the two opposite side walls of the clamping groove along the second direction forms a second limiting portion 432.

[0097] The flushing pipeline 1b and the suction pipeline 1a are clamped between two first limiting portions 431 along the first direction, and the first pipeline 1 is clamped between the two second limiting portions 432 of the corresponding second limiting member 43 along the second direction.

[0098] Exemplarily, the clamping groove is a U-shaped groove. In other embodiments, the clamping groove can also be a C-shaped clamping groove, etc.

[0099] Furthermore, any first limiting member 42 is integrally formed on any pipeline joint 41. In this way, the connection stability between the first limiting member 42 and the pipeline joint 41 can be improved.

[0100] Furthermore, as Figure 2 and Figure 8 shown, the sub-pipeline 11 is inserted into the pipeline joint 41 in an interference fit manner. The connection method between the sub-pipeline 11 and the pipeline joint 41 is simple, and the disassembly and assembly are convenient.

[0101] Furthermore, as Figure 2 and Figure 8As shown, a sealant, such as UV glue, is provided between the sub-pipeline 11 and the pipeline joint 41. With this arrangement, it is possible to prevent liquid leakage at the connection position between the sub-pipeline 11 and the pipeline joint 41 and improve the sealing performance.

[0102] Furthermore, as Figure 4 shown, the pipeline fixing structure 4 is disposed in the installation chamber; two second limiting members 43 are fixedly attached to the inner walls of the corresponding half-shells 5 one by one.

[0103] In this embodiment, a reinforcing rib 433 is connected between the half-shell 5 and the second limiting member 43, and the connection stability between the half-shell 5 and the second limiting member 43 is improved through the reinforcing rib 433 to prevent the second limiting member 43 from shaking.

[0104] Exemplarily, reinforcing ribs 433 are provided at both ends of the second limiting member 43 in the second direction, making full use of the space at both ends of the second limiting member 43 in the second direction.

[0105] Furthermore, as Figure 4 shown, the second limiting member 43 and the reinforcing rib 433 are both integrated with the corresponding half-shell 5 into an integrally formed structural member. With this arrangement, the installation of the second limiting member 43 and the reinforcing rib 433 can be simplified.

[0106] Embodiment 2

[0107] The difference between this embodiment and Embodiment 1 is that, as Figure 10 and Figure 11 shown, the elastic reset member 32 is a telescopic spring 32a, and the partitioning structure 2 further includes a reset mounting portion 25 that corresponds to the pipelines 1 one by one and is connected to the partition plate 21, and the elastic reset member 32 is disposed between the extrusion portion 312 and the reset mounting portion 25.

[0108] Exemplarily, the telescopic spring 32a is a compression spring, and the reset mounting portion 25 is located on the side of the extrusion portion 312 facing away from the support base 22.

[0109] Specifically, a first installation groove is formed on the side of the extrusion portion 312 facing away from the support base 22, a second installation groove is provided on the side of the reset mounting portion 25 facing the extrusion portion 312, one end of the telescopic spring 32a is disposed in the first installation groove, and the other end is disposed in the second installation groove. With this arrangement, it is possible to prevent the telescopic spring 32a from bending and twisting.

[0110] In other embodiments, the telescopic spring 32a can also be set as a tension spring, and the reset mounting portion 25 is located on the side of the extrusion portion 312 facing the support base 22.

[0111] Furthermore, as Figure 12 and Figure 13As shown, an arc-shaped groove is formed on one side of the extrusion part 312 facing the pipe 1, and an arc-shaped boss 221 is provided on the side of the support base 22 facing the pipe 1. The pipe 1 can be clamped between the arc-shaped boss 221 and the inner wall of the arc-shaped groove to cut off the pipe 1.

[0112] With such a setting, it is beneficial for the arc-shaped boss 221 and the arc-shaped groove to cooperate to cut off the pipe 1, improve the cutting effect, and avoid liquid leakage after the pipe 1 is cut off.

[0113] In this embodiment, as Figure 11 , Figure 13 and Figure 14 shown, a plurality of first positioning members 24 are provided on either side of the partition structure 2 in the first direction, and the plurality of first positioning members 24 are arranged in two rows in the second direction. Exemplarily, the first positioning member 24 is a positioning post integrally formed on the partition structure 2, and the second positioning member 53 is a positioning boss protruding from the inner wall of the half shell 5. A positioning hole is provided on the positioning boss, and the positioning post is axially inserted into the positioning hole. The partition structure 2 is clamped between the positioning bosses on the two half shells 5 in the first direction. There is no need to separately provide a structure for installing and fixing the partition structure 2. Just by the cooperation of the plurality of first positioning members 24 and the plurality of second positioning members 53, the partition structure 2 can be fixed in the flushing and suction housing, with a simple structure and low cost.

[0114] Exemplarily, the first positioning members 24 on both sides of the partition structure 2 in the first direction are arranged in one-to-one correspondence, and the correspondingly arranged first positioning members 24 are integrally formed into a long rod.

[0115] It should be noted that in this embodiment, the two arc-shaped bosses 221 also serve as a first positioning member 24 respectively, reducing the number of components and improving the integration degree of the partition structure 2.
