Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a flushing aspirator button assembly and a flushing aspirator. Background Art

[0002] Flushing and suction devices are common auxiliary instruments in clinical practice. They are used to remove bleeding, exudate, pus, and contents of chest organs during surgery, making the surgical field of view clearer and reducing the chance of contamination. They are widely used in surgery. During surgery, doctors sometimes need to continuously flush and suction to flush in a large amount of saline / absorb a large amount of waste. Sometimes, flushing and suctioning are required intermittently to avoid excessive suction affecting the pneumoperitoneum pressure and to avoid excessive suction of the suction tube on the tissue causing compression.

[0003] Existing irrigation and suction devices are mainly divided into two types: electric and manual. Electric irrigation and suction devices are expensive, while manual irrigation and suction devices cannot meet the requirements of both intermittent irrigation and suction and continuous irrigation and suction at the same time. Utility Model Content

[0004] In view of the problems in the prior art, the purpose of the present application is to provide a flushing and aspirator button assembly and a flushing and aspirator, which can meet both intermittent flushing and aspiration and continuous flushing and aspiration requirements.

[0005] The first aspect of the present application provides a flushing aspirator button assembly, comprising:

[0006] The main body connecting portion is provided with at least one stop groove;

[0007] a pipeline connection portion connected to the main body connection portion; and

[0008] a button mounted on the first end of the main body connection portion and configured to move toward the second end of the main body connection portion when pressed to control the internal cavity of the pipeline connection portion to communicate with the internal cavity of the main body connection portion;

[0009] Wherein, the button is provided with a matching portion, and when the matching portion moves toward the second end of the main connecting portion until it is embedded in the stopping groove, the stopping groove blocks the matching portion from moving in a direction away from the second end of the main connecting portion.

[0010] In some embodiments, the outer side surface of the main connecting portion is provided with a guide groove extending along the axial direction of the main connecting portion, the side wall of the guide groove is connected to the stop groove, and the matching portion is configured to move along the guide groove to a communication position with the stop groove when the button is pressed, and enter the stop groove when the button is rotated.

[0011] In some embodiments, a plurality of the stop grooves are alternately arranged on both sides of the guide groove.

[0012] In some embodiments, the extension direction of the stop groove forms an acute angle with the extension direction of the guide groove, and when the matching portion is embedded in the stop groove and the button is pressed, the matching portion moves toward the second end of the main connecting portion and disengages from the stop groove.

[0013] In some embodiments, an elastic member is provided between the main body connection portion and the button, and the elastic member is configured to apply a biasing force to the button to move it away from the second end of the main body connection portion.

[0014] In some embodiments, the button includes a pressing portion and a hollow pressing rod, wherein the pressing rod portion is located in the internal cavity of the main body connecting portion, and the pressing portion is located on the outside of the main body connecting portion. When the mating portion is embedded in the stop groove, the internal cavity of the pipeline connecting portion is connected to the internal cavity of the main body connecting portion through the pressing rod.

[0015] In some embodiments, the matching portion is disposed on a side of the pressing portion facing the main body connecting portion, and the matching portion is a hook protruding toward the inside.

[0016] In some embodiments, a limiting portion is provided at the first end of the main connecting portion, and when the button is not pressed, the limiting portion abuts against the matching portion to prevent the matching portion from detaching from the first end of the main connecting portion.

[0017] In some embodiments, the outer surface of the pressing portion is further provided with a raised operating portion, and the operating portion is configured to drive the button to rotate when subjected to an external force along the circumference of the pressing portion;

[0018] The operating portion includes a plurality of ribs evenly distributed along the circumference of the pressing portion, and each of the ribs extends along the axial direction of the main body connecting portion.

[0019] A second aspect of the present application provides an irrigation aspirator, comprising the irrigation aspirator button assembly.

[0020] The flushing aspirator button assembly and flushing aspirator provided by the present application have the following advantages:

[0021] By adopting the button assembly of the present application, when the button is pressed, the internal cavity of the pipeline connecting part and the internal cavity of the main body connecting part can be connected, the switch of the flushing pipeline or the suction pipeline can be turned on, and the flushing and suction or suction function can be realized through the flushing and suction device. When the button is pressed but the matching part is not embedded in the stop groove, the button is released, and the button can return to its original position without obstruction to close the pipeline switch. By repeatedly pressing the button, the intermittent flushing and suction function can be realized. After the button is pressed and the matching part is embedded in the stop groove, the button is released, and the stop groove blocks the button from returning to its original position, so that the button is suspended at the position corresponding to the stop groove, keeping the pipeline continuously open, thereby realizing continuous flushing and suction. Therefore, the button assembly of the present application meets both intermittent flushing and suction and continuous flushing and suction requirements, and has a simple structure and low cost.

Although the terms "upper", "lower", "left", "right", "between", etc. may be used in this specification to describe different exemplary features and elements of the present application, these terms are used herein only for convenience, such as according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional direction of the structure to fall within the scope of the present application. Although "first" or "second" etc. are used in this specification to represent certain features, they are only used to represent the function, and are not used as a limitation on the number and importance of specific features.

[0042] The present application provides a flushing aspirator button assembly and a flushing aspirator including the same. The flushing aspirator includes at least one flushing aspirator button assembly, which is used to control the switch of the liquid channel between the flushing pipeline / suction pipeline and the flushing aspirator body. The flushing aspirator button assembly includes a main body connecting part, a pipeline connecting part and a button. The main body connecting part is used to connect with the flushing aspirator body. The pipeline connecting part is connected to the main body connecting part and is used to connect with the flushing pipeline or the suction pipeline. The button is installed at the first end of the main body connecting part and is configured to move toward the second end of the main body connecting part when pressed, so as to control the internal cavity of the pipeline connecting part to be connected with the internal cavity of the main body connecting part.

[0043] The main connecting part is provided with at least one stop groove, and the button is provided with a matching part. When the matching part moves toward the second end of the main connecting part and is embedded in the stop groove, the stop groove blocks the matching part from moving in a direction away from the second end of the main connecting part. When in use, the doctor can open the switch of the flushing line or the suction line by pressing the button. When the button is pressed but the matching part is not embedded in the stop groove, the intermittent flushing and suction function can be realized. When the button is pressed and the matching part is embedded in the stop groove, continuous flushing and suction can be realized. Both intermittent flushing and suction and continuous flushing and suction requirements are met at the same time, and the structure is simple and the cost is low.

[0044] The structure of the flushing aspirator button assembly and the flushing aspirator in a specific embodiment is described in detail below in conjunction with the accompanying drawings. It is understandable that the structure shown in the accompanying drawings and the following description are only examples and are not intended to limit the scope of protection of this application.

[0045] Figure 1 The structure of a flushing aspirator according to an embodiment of the present application is shown. The flushing aspirator comprises a flushing aspirator tube 91, a flushing aspirator body 92, a flushing button assembly 93 and a suction button assembly 94. The internal cavity of the flushing aspirator body 92 is connected to the flushing aspirator tube 91. The flushing button assembly 93 is used to control the switch of the liquid passage between the flushing pipeline (not shown in the figure) and the flushing aspirator body 92, and the suction button assembly 94 is used to control the switch of the liquid passage between the suction pipeline (not shown in the figure) and the flushing aspirator body 92. The flushing button assembly 93 and the suction button assembly 94 can both adopt the structure of the button assembly of the present application, or only one of them can adopt the structure of the button assembly of the present application, while the other can adopt other button assembly structures, all of which belong to the protection scope of the present application.

[0046] like Figures 2 to 4 As shown, the flushing suction button assembly includes a button 1, a main body connection part 2 and a pipeline connection part 3. The main body connection part 2 includes a first end and a second end along the axial direction, respectively corresponding to Figure 2 The left and right ends of the main body connection part 2, the first end of the main body connection part 2 is connected to the button 1, and the second end is connected to the flushing and aspirating device body. The interior of the main body connection part 2 forms an internal cavity extending in the axial direction, which is defined as a first channel 24 here, and the right end of this first channel 24 is connected to the internal cavity of the flushing and aspirating device body 92. The upper end of the pipeline connection part 3 is connected to the side of the main body connection part 2, and the lower end of the pipeline connection part 3 is used to connect to the flushing pipeline or the suction pipeline (depending on whether the button assembly is specifically for controlling the flushing function or the suction function, it is selected to connect the lower end of the pipeline connection part 3 to the flushing and aspiration pipeline or the suction pipeline).

[0047] The button 1 is mounted on the first end of the main connecting portion 2. Figures 2 to 4 As shown, in the initial state, when the button 1 is not pressed, the button 1 is in the initial position, and the first channel 24 of the main body connection part 2 is not connected to the internal cavity of the pipeline connection part 3. When the doctor presses the button 1, the button 1 moves toward the second end of the main body connection part 2, and when it moves to the specified position range, the internal cavity of the pipeline connection part 3 is controlled to be connected to the first channel 24 of the main body connection part 2. Specifically, the button 1 includes a pressing part 11 and a hollow pressing rod 13, the pressing part 11 is located outside the first end of the main body connection part 2, the left side of the pressing rod 13 is fixedly connected to the pressing part 11, and the pressing rod 13 is partially located in the first channel 24 of the main body connection part 2. The internal cavity of the pressing rod 13 is defined as a second channel 131, the left end of the second channel 131 is closed, and the right end is connected to the first channel 24. A plurality of sealing members 5 are provided between the outer wall of the pressing rod 13 and the inner wall of the main body connection part 2, such as O-rings. The side wall of the pressing rod 13 is provided with at least one liquid passage 132. In the initial state, the button 1 is in the initial position, the liquid passage 132 is located on the left side of the upper opening of the pipeline connection part 3, and under the sealing effect of the sealing member 5, the liquid passage 132 is not connected with the pipeline connection part 3. At this time, liquid communication from the pipeline connection part 3 to the first channel 24 cannot be formed, that is, the button assembly is in a functional closed state. When the pressing part 11 is pressed, the pressing rod 13 moves toward the second end of the main body connection part 2 (moves to the right) together with the pressing part 11, and moves until the liquid passage 132 is at least partially connected with the upper opening of the pipeline connection part 3, so that the liquid passage from the pipeline connection part 3 through the second channel 131 to the first channel 24 is connected, that is, the button assembly is in a functional open state. The above-mentioned specified position range is the position range that can meet the requirement that the liquid passage 132 is at least partially connected with the upper opening of the pipeline connection part 3. Therefore, by pressing the pressing portion 11 of the button 1, the switch of the irrigation function or the suction function can be turned on, and the irrigation or suction function can be performed by the irrigation and suction device.

[0048] The pressing portion 11 is provided with a matching portion 12 on one side (right side) facing the main connecting portion 2. The matching portion 12 is a hook protruding toward the inside. The first end of the main connecting portion 2 is provided with a limiting portion 23. When the button 1 is not pressed, the limiting portion 23 is located on the left side of the matching portion 12 and abuts against the matching portion 12, preventing the matching portion 12 from being separated from the first end of the main connecting portion 2, thereby maintaining the connection and matching between the button 1 and the main connecting portion 2. The outer surface of the main connecting portion 2 is provided with at least one stop groove 22, and the stop groove 22 is not connected to the first channel 24. When the mating portion 12 moves along with the button 1 toward the second end of the main connecting portion 2 until it is embedded in the stop groove 22, the button 1 is located within the above-mentioned specified position range, and the pressing rod 13 controls the internal cavity of the pipe connecting portion 3 to be connected with the first channel 24 of the main connecting portion 2, and the stop groove 22 blocks the mating portion 12 from moving in the direction away from the second end of the main connecting portion 2, so that the button 1 is suspended at the position corresponding to the stop groove 22, thereby keeping the button assembly in a function-on state.

[0049] like Figure 3 As shown, an elastic member 4 is provided between the first end of the main body connection part 2 and the pressing part 11, and the elastic member 4 is, for example, a spring, a spring sheet, an elastic pad, etc. The elastic member 4 applies a biasing force to the pressing part 11 to make it move in a direction away from the second end of the main body connection part 2. When the matching part 12 is embedded in the stop groove 22, the internal cavity of the pipeline connection part 3 is connected to the first channel 24 of the main body connection part 2 through the pressing rod 13, and the stop groove 22 blocks the matching part 12 from moving in a direction away from the second end of the main body connection part 2. Therefore, when the doctor uses the button assembly, if intermittent flushing or suction function is required, the button 1 can be directly pressed without the matching part 12 being embedded in the stop groove 22, and the internal liquid passage is connected through the pressing rod 13 to open the flushing function or suction function. After the doctor releases the button 1, the button 1 can return to its original position without being blocked under the biasing force of the elastic member 4 to close the flushing or suction function. By repeatedly pressing the button 1, the flushing or suction function can be intermittently opened. If the doctor needs continuous flushing or suction function, he presses the button 1 and makes the matching part 12 embed into the stop groove 22, then releases the button 1. Under the stopping effect of the stop groove 22 on the matching part 12, the button 1 is maintained in the position when it is pressed, and the pipeline is kept in the open state, so that continuous flushing or suction can be achieved.

[0050] In this embodiment, the outer side surface of the main body connection part 2 is provided with a guide groove 21 extending along the axial direction of the main body connection part 2, the side wall of the guide groove 21 is connected to the stop groove 22, and the guide groove 21 is not connected to the first channel 24. The matching portion 12 is configured to move along the guide groove 21 when the button 1 is pressed, and enter the stop groove 22 when the button 1 is rotated. In the initial state, the matching portion 12 is located at the left end of the guide groove 21. When the doctor presses the button 1 along the axial direction of the main body connection part 2 and does not rotate the button 1, the matching portion 12 moves along the extension direction of the guide groove 21 and does not enter the stop groove 22. The doctor presses the button 1 along the axial direction, and when the matching portion 12 moves to the communication position of the stop groove 22 and the guide groove 21, the button 1 is rotated in the direction of the stop groove 22, so that the matching portion 12 can enter the stop groove 22 and be engaged with the stop groove 22. In order to facilitate the doctor's rotation operation, the outer surface of the pressing portion 11 is further provided with a raised operating portion 14, and the operating portion 14 is configured to drive the button 1 to rotate when subjected to an external force along the circumference of the pressing portion 11. In this embodiment, the operating portion 14 includes a plurality of ribs evenly distributed along the circumference of the pressing portion 11, and each of the ribs extends along the axial direction of the main body connecting portion 2, so that the doctor can conveniently rotate the button 1 at all angles, but the present application is not limited thereto. In other alternative embodiments, the operating portion 14 may also adopt other raised structures, such as only one boss or two symmetrically arranged convex strips, etc., all of which fall within the protection scope of the present application.

[0051] The number of the stop grooves 22 may be one or more. When a plurality of stop grooves 22 are provided, the plurality of stop grooves 22 are arranged in the axial direction of the main body connecting portion 2 to achieve different gear control. The number of the stop grooves 22 and the spacing between adjacent stop grooves 22 can be set as needed. This embodiment is described by taking five stop grooves 22 as an example. The five stop grooves 22 are staggered on both sides of the guide groove 21, that is, two stop grooves 22 are provided on the upper side of the guide groove 21, and three stop grooves 22 are provided on the lower side of the guide groove 21, and the five stop grooves 22 are arranged in sequence in the axial direction, from the leftmost stop groove 22 to the rightmost stop groove 22, and each stop groove 22 corresponds to the first gear, the second gear, the third gear, the fourth gear and the fifth gear respectively. By staggering a plurality of stop grooves 22 on both sides of the guide groove 21, more gear settings can be achieved in a smaller space, and two adjacent gears are respectively provided on the upper and lower sides of the guide groove 21, and the spacing between them in the axial direction can be set very small without interfering with each other. Figure 5 2 shows the structure when the matching portion 12 is embedded in the stop groove 22 of the first gear. Figure 6 The structure when the engaging portion 12 is inserted into the stopper groove 22 in the fourth gear is shown. Figure 7The structure of the stop groove 22 when the matching part 12 is embedded in the fifth gear is shown. When the matching part 12 is embedded in the stop groove 22 of the first gear, the conduction range between the liquid port 132 and the opening of the pipeline connecting part 3 is the smallest, and the conduction flow rate of the liquid channel inside the button assembly is the smallest. The larger the gear of the stop groove 22 in which the matching part 12 is embedded, the larger the conduction flow rate of the liquid channel. That is, by setting different gears, when the button 1 is suspended at the position of the stop groove 22 of each gear, multi-gear control of the liquid flow rate during flushing or suction is achieved. In addition, by reasonably designing the spacing between multiple stop grooves 22, a linear increase in the conduction flow rate from the first gear to the fifth gear can be achieved.

[0052] In this embodiment, after the doctor presses the button 1 and rotates the button 1 so that the matching portion 12 is embedded in the stop groove 22, continuous flushing or suction can be achieved. If the doctor needs to turn off the flushing or suction function at this time, the doctor can rotate the button 1 in the reverse direction (opposite to the rotation direction when the matching portion 12 is embedded in the stop groove 22) so that the matching portion 12 comes out of the stop groove 22 and returns to the guide groove 21. At this time, the button 1 is released, and under the biasing force of the elastic member 4, the button 1 can return to the initial position and turn off the corresponding function. When the doctor needs to change gears, he can rotate the button 1 in the opposite direction to make the matching part 12 come out of the stop groove 22 of the low gear, and then continue to press the button 1 to make the matching part 12 further move to the connecting position corresponding to the stop groove 22 of the high gear, and rotate the button 1 again to make the matching part 12 embed into the stop groove 22 of the high gear, thereby realizing the switch from the low gear to the high gear; or, the doctor can rotate the button 1 in the opposite direction to make the matching part 12 come out of the stop groove 22 of the high gear, and then reduce the pressing force applied to the button 1 to make the matching part 12 move to the left to the connecting position corresponding to the stop groove 22 of the low gear, and then rotate the button 1 again to make the matching part 12 embed into the stop groove 22 of the low gear, thereby realizing the switch from the high gear to the low gear.

[0053] like Figures 5 to 7As shown, the extension direction of the stop groove 22 forms an acute angle with the extension direction of the guide groove 21. When the matching portion 12 is embedded in the stop groove 22, the stop groove 22 does not block the movement of the matching portion 12 toward the second end of the main body connecting portion 2. Therefore, when the matching portion 12 is embedded in a stop groove 22, the doctor does not need to reversely rotate the button 1, but only needs to continue to press the button 1. Under the guidance of the inclined stop groove 22, the matching portion 12 can also be separated from the stop groove 22 and return to the guide groove 21. At this time, the doctor can release the button 1 to reset the button 1 and turn off the flushing and suction function, or continue to press the button 1 to achieve gear shifting. For example, when the matching portion 12 is embedded in the stop groove 22 of the low gear, the button 1 can be directly continued to be pressed. Under the guidance of the inclined stop groove 22, the matching portion 12 is disengaged from the stop groove 22 of the low gear and enters the guide groove 21. Then, the matching portion 12 continues to move toward the second end of the main connecting portion 2 to the connecting position of the stop groove 22 of the high gear. When the doctor rotates the button 1, the matching portion 12 enters the stop groove 22 of the high gear, thereby realizing the switching from the low gear to the high gear.

[0054] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
