Description

Technical Field

[0001] This invention relates to the field of medical technology, and more specifically, to a multifunctional integrated neurosurgical suction device. Background Technology

[0002] Surgeons thoroughly irrigate the surgical field or related body cavities during or before closing the incision at the end of surgery. This helps maintain a clear surgical field and removes residual necrotic tissue, blood clots, contaminated or infected fluids, and exfoliated tumor cells from the surgical wound to the greatest extent possible. This reduces the risk of infection at the surgical site, residual abscesses, or implantation metastasis in patients with malignant tumors.

[0003] In actual surgical procedures, the continuous rinsing of the surgical site and the aspiration of waste fluid occur simultaneously. This necessitates the use of both a rinsing and aspiration instruments, requiring constant switching between them. This coordination during surgery is quite cumbersome and wastes surgical time. More importantly, the rinsing fluid may flow into non-surgical areas if it cannot be immediately aspirated, potentially causing tissue infection. Furthermore, in minimally invasive surgery, such constant switching is almost impossible, causing significant inconvenience. Currently, to avoid frequent switching between rinsing and aspiration instruments, existing techniques connect a flexible rubber drainage tube to the suction tube, keeping the suction device constantly open. The surgeon controls the suction by folding the rubber drainage tube. While this method reduces the difficulty of operation, the suction tube remains constantly placed at the surgical site, potentially causing pressure or even damage to local tissues, compromising surgical safety. Therefore, a multifunctional integrated neurosurgical suction device is proposed. Summary of the Invention

[0004] In view of the problems that existing irrigation and aspiration instruments need to be constantly changed during use, which is quite troublesome to coordinate during surgery and wastes surgical time, the purpose of this invention is to provide a multifunctional integrated neurosurgical aspirator.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A multifunctional integrated neurosurgical suction device includes an integrated flushing and suction tube, a three-way tube, and an electromagnetic valve body. The three-way tube has three sets of ports, which are respectively set as a common port, a suction port, and a flushing port. One end of the integrated flushing and suction tube is connected to the common port of the three-way tube. An electromagnetic valve body is provided in both the suction port and the flushing port of the three-way tube.

[0007] It also includes a switching mechanism capable of alternately switching the on and off of two sets of solenoid valves. The switching mechanism includes a rotating shaft, a housing, movable conductive plates, fixed conductive plates, and a push plate. There are two sets of both movable and fixed conductive plates, and one set of movable conductive plates and one set of fixed conductive plates constitute a control switch. The two sets of control switches control the two sets of solenoid valves respectively. The two sets of movable conductive plates are located on both sides of the push plate. The push plate is rotatably connected to the housing through the rotating shaft. The two sets of fixed conductive plates are located on the inner surface of the housing, and the two sets of fixed conductive plates are located in the direction of movement of the movable conductive plates. The central angle between the two sets of fixed conductive plates is greater than the central angle between the two sets of movable conductive plates.

[0008] Optionally, a cutting mechanism is provided between the movable conductive sheet and the push plate, and the cutting mechanism causes the movable conductive sheet to move radially along the rotating shaft.

[0009] Optionally, each cutting mechanism includes a vertical groove, a slider, a connecting rod, a pull rope, a telescopic plate, an outer cylinder, a pressure plate, and a return component. The outer cylinder is fixedly connected to the push plate and is positioned in the radial direction of the rotating shaft. The telescopic plate is fitted inside the outer cylinder and forms a sliding pair therein. One side of the telescopic plate is fixedly connected to a movable conductive sheet, and the other side of the telescopic plate is fixedly connected to one end of the pull rope. The other end of the pull rope is fixedly connected to the slider. The vertical groove is formed inside the push plate, and the slider is fitted inside the vertical groove and forms a sliding pair. One end of the connecting rod is fixedly connected to the slider, and the other end of the connecting rod passes through the push plate and is fixedly connected to the pressure plate. By pressing the pressure plate, the telescopic plate and the movable conductive sheet can be moved. A return component is provided between the telescopic plate and the outer cylinder.

[0010] Optionally, the return component includes guide rods fixedly installed on both sides inside the outer cylinder. The guide rods pass through both sides of the telescopic plate and slide with it. Springs are sleeved on the surface of each guide rod. When the telescopic plate moves, the springs are either extended or compressed.

[0011] Optionally, the switching mechanism further includes a housing, which is a hollow cylindrical structure, and an arc-shaped groove is provided on the surface of the housing. One side of the push plate extends to the outside of the housing through the arc-shaped groove. Arc-shaped baffles are fixedly connected to both sides of the push plate, and the arc-shaped baffles form a rotating pair with the inner surface of the housing.

[0012] Optionally, the three-way pipe and the solenoid valve body are both located inside the housing, and the suction port and flushing port of the flushing and suction pipe and the three-way pipe extend to the outside of the housing.

[0013] Optionally, the flushing and suction integrated tube includes a fixed end and a movable end. The fixed end of the flushing and suction integrated tube is connected to the common port of the tee pipe. The fixed end and the movable end of the flushing and suction integrated tube are connected by a threaded structure.

[0014] Optionally, a filter cartridge is connected through the middle of the fixed end of the flushing and suction pipe. With the water suction direction as the reference, the connection ports of the filter cartridge and the flushing and suction pipe are sequentially set as a first port and a second port. A fixed filter plate is fixedly installed at the second port where the filter cartridge is connected to the flushing and suction pipe. A movable filter plate is also provided on the inner surface of the filter cartridge. The movable filter plate can rotate on the inner surface of the filter cartridge and can block or move away from the first port.

[0015] Optionally, a rotating rod is rotatably connected to the inner surface of the filter cartridge, and the surface of the rotating rod is fixedly connected to the movable filter plate by a connecting frame. A transmission wheel is fixedly connected to one end of the rotating rod and one end of the rotating shaft, and a transmission belt is sleeved on the surface of the two sets of transmission wheels.

[0016] Optionally, when the switching mechanism controls the solenoid valve body on the liquid suction port of the three-way tube to open, the movable filter plate is misaligned with the first port; when the switching mechanism controls the solenoid valve body on the liquid flushing port of the three-way tube to open, the movable filter plate blocks the first port.

[0017] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0018] In the above solution, the surgical aspirator in this embodiment has both rinsing and aspiration functions. The switching between the two functions is achieved through a switching mechanism. In actual use, the operator can hold the housing of the surgical aspirator with one hand and use the thumb to push and pull the push plate back and forth, so that the two sets of movable conductive plates alternately contact the corresponding fixed conductive plates. The two sets of control switches formed by the movable conductive plates and the fixed conductive plates can be activated alternately, thereby opening the solenoid valves of the suction port and the rinsing port of the three-way tube alternately, thus realizing the switching between rinsing and aspiration functions.

[0019] By setting a cutting mechanism, this surgical aspirator can be configured to have only the corresponding rinsing or aspiration functions to meet the needs of different surgical situations. When only the rinsing function is needed, the pressure plate corresponding to the aspiration function can be pressed and the push plate can be pushed to make only the movable conductive piece controlling the rinsing function contact the fixed conductive piece, thereby achieving the rinsing function only. When only the aspiration function is needed, the pressure plate corresponding to the rinsing function can be pressed and the push plate can be pushed to make only the movable conductive piece controlling the aspiration function contact the fixed conductive piece, thereby achieving the aspiration function only.

[0020] By using a fixed filter plate, tissue fragments in the surgical fluid can be filtered out during aspiration, preventing them from clogging the solenoid valve and causing damage. By using a movable filter plate, when the push plate is pushed to switch the switching mechanism to the flushing function, the movable filter plate can block the flow at the first port, preventing the flushing fluid from dispersing the tissue fragments on the fixed filter plate. By blocking the first port, these tissue fragments can be prevented from flowing back into the patient's body through the first port. Attached Figure Description

[0038] The following is a detailed description of a multifunctional integrated neurosurgical suction device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0039] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0040] Generally, terms can be understood at least partly from their use in context.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0041] It is understood that the meanings of “on”, “above”, and “above” in this invention should be interpreted in the broadest manner, such that “on” means not only “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” means not only “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0042] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings. Spatially related terms are intended to cover different orientations in the use or operation of the device other than those depicted in the accompanying drawings.

[0043] like Figures 1 to 9 As shown, this embodiment of the invention provides a multifunctional integrated neurosurgical suction device, including a flushing and suction tube 1, a three-way tube 2, and an electromagnetic valve body 3. The three ports of the three-way tube 2 are respectively set as a common port, a suction port, and a flushing port. One end of the flushing and suction tube 1 is connected to the common port of the three-way tube 2. An electromagnetic valve body 3 is provided in both the suction port and the flushing port of the three-way tube 2.

[0044] It also includes a switching mechanism 4 capable of alternately switching the on and off of two sets of solenoid valve bodies 3. The switching mechanism 4 includes a rotating shaft 41, a housing 42, movable conductive plates 43 and fixed conductive plates 44, and a push plate 47. There are two sets of movable conductive plates 43 and two sets of fixed conductive plates 44. One set of movable conductive plates 43 and one set of fixed conductive plates 44 form a control switch. The two sets of control switches control the two sets of solenoid valve bodies 3 respectively. The two sets of movable conductive plates 43 are located on both sides of the push plate 47. The push plate 47 is rotatably connected to the housing 42 through the rotating shaft 41. The two sets of fixed conductive plates 44 are located on the inner surface of the housing 42. The two sets of fixed conductive plates 44 are located in the moving direction of the movable conductive plates 43. The central angle between the two sets of fixed conductive plates 44 is greater than the central angle between the two sets of movable conductive plates 43.

[0045] The switching mechanism 4 also includes a housing 42, which is a hollow cylindrical structure. An arc-shaped groove 46 is provided on the surface of the housing 42. One side of the push plate 47 extends to the outside of the housing 42 through the arc-shaped groove 46. Arc-shaped baffles 45 are fixedly connected to both sides of the push plate 47, and the arc-shaped baffles 45 and the inner surface of the housing 42 form a rotating pair.

[0046] In actual use, the arc-shaped baffle 45 can move with the push plate 47. The arc-shaped baffle 45 can always cover the arc-shaped groove 46 on the housing 42, so that the housing 42 has a certain degree of sealing. In addition, the housing 42, the push plate 47 and the arc-shaped baffle 45 can all be made of insulating materials to ensure safety during use.

[0047] The three-way pipe 2 and the solenoid valve body 3 are both located inside the housing 42, while the suction port and flushing port of the flushing and suction pipe 1 and the three-way pipe 2 extend to the outside of the housing 42.

[0048] In this embodiment, the solenoid valve body 3 can be any existing model of solenoid valve to meet simple liquid outflow control. The model of the solenoid valve body 3 can be BZCD-1. At the same time, a battery assembly can be set in the housing 42 or any other part to provide the corresponding power to the solenoid valve body 3. If a solenoid valve that can control the corresponding flow rate is used, a controller can also be added as a controller. The controller can be a PCB control board or a micro single-chip microcomputer, etc. The model is not required here.

[0049] The surgical aspirator in this embodiment has both rinsing and aspiration functions. The switching between the two functions is achieved through the switching mechanism 4. Specifically, in actual use, the operator can hold the housing 42 of the surgical aspirator with one hand and use the thumb to push and pull the push plate 47 back and forth, so that the two sets of movable conductive plates 43 alternately contact the corresponding fixed conductive plates 44. The two sets of control switches formed by the movable conductive plates 43 and the fixed conductive plates 44 can be activated alternately, thereby opening the solenoid valves 3 of the suction port and the rinsing port of the three-way tube 2 alternately, thus realizing the switching between the rinsing function and the aspiration function.

[0050] like Figures 3 to 6 As shown, a cutting mechanism 5 is provided between the movable conductive sheet 43 and the push plate 47. The cutting mechanism 5 causes the movable conductive sheet 43 to move radially along the rotating shaft 41.

[0051] Each of the cutting mechanisms 5 includes a vertical groove 51, a slider 52, a connecting rod 53, a pull rope 54, a telescopic plate 55, an outer cylinder 56, a pressure plate 59, and a return component. The outer cylinder 56 is fixedly connected to the push plate 47 and is arranged in the radial direction of the rotating shaft 41. The telescopic plate 55 is fitted inside the outer cylinder 56 and forms a sliding pair inside it. One side of the telescopic plate 55 is fixedly connected to the movable conductive sheet 43, and the other side of the telescopic plate 55 is fixedly connected to one end of the pull rope 54. The other end of the pull rope 54 is fixedly connected to the slider 52. The vertical groove 51 is opened inside the push plate 47. The slider 52 is fitted inside the vertical groove 51 and forms a sliding pair. One end of the connecting rod 53 is fixedly connected to the slider 52, and the other end of the connecting rod 53 passes through the push plate 47 and is fixedly connected to the pressure plate 59. By pressing the pressure plate 59, the telescopic plate 55 and the movable conductive sheet 43 can be moved. A return component is provided between the telescopic plate 55 and the outer cylinder 56.

[0052] In this embodiment, by setting the cutting mechanism 5, the surgical aspirator can have only the corresponding rinsing or aspiration functions to meet the needs of use in different surgical situations. Specifically, when only the rinsing function is needed, the pressure plate 59 corresponding to the aspiration function can be pressed, which will drive the connecting rod 53 and the slider 52 to move down along the vertical groove 51. The slider 52 can then drive the telescopic plate 55 and the movable conductive sheet 43 corresponding to the aspiration function to move through the pull rope 54, so that the movable conductive sheet 43 is separated from the corresponding fixed conductive sheet 44, thereby cutting off the aspiration function. At this time, pushing the push plate 47 can make only the movable conductive sheet 43 controlling the rinsing function contact the fixed conductive sheet 44. And at this time, repeatedly pushing and pulling the push plate 47 can make the movable conductive sheet 43 controlling the rinsing function repeatedly separate and contact the fixed conductive sheet 44, thereby achieving the effect of spot rinsing. Similarly, when only the aspiration function is needed, the pressure plate 59 corresponding to the rinsing function can be pressed.

[0053] The recovery component includes guide rods 58 fixedly installed on both sides inside the outer cylinder 56. The guide rods 58 pass through both sides of the telescopic plate 55 and slide with it. Springs 57 are sleeved on the surface of each guide rod 58. When the telescopic plate 55 moves, the springs 57 are in an extended or compressed state.

[0054] In this embodiment, the return of the telescopic plate 55 and the movable conductive sheet 43 is achieved by the spring 57. Specifically, when the pressure plate 59 is pressed to move the telescopic plate 55 and the movable conductive sheet 43, the spring 57 sleeved on the surface of the guide rod 58 is compressed, thereby accumulating elastic potential energy. When the pressure plate 59 is released, the accumulated elastic potential energy is released, thereby driving the telescopic plate 55 and the movable conductive sheet 43 to move back to their original positions. In actual use, other moving mechanisms with reset functions can also be selected for the return component, such as using a cylinder to reset the telescopic plate 55 and the movable conductive sheet 43 according to the change in air pressure, which will not be elaborated here.

[0055] The flushing and suction integrated tube 1 includes a fixed end and a movable end. The fixed end of the flushing and suction integrated tube 1 is connected to the common port of the three-way tube 2. The fixed end and the movable end of the flushing and suction integrated tube 1 are connected by a threaded structure.

[0056] During use in this embodiment, the flushing and suction tube 1 will wear out over time and needs to be replaced. In this embodiment, the flushing and suction tube 1 is assembled from a fixed end and a movable end by threads. When replacing it, since the movable end of the flushing and suction tube 1 is in direct contact with the surgical site, the wear will be relatively high. Therefore, the movable end of the flushing and suction tube 1 can be replaced directly.

[0057] like Figure 7 As shown, a filter cylinder 8 is connected through the middle of the fixed end of the flushing and suction pipe 1. With the water suction direction as the reference, the connection ports of the filter cylinder 8 and the flushing and suction pipe 1 are set as the first port and the second port in sequence. A fixed filter plate 10 is fixedly installed at the second port where the filter cylinder 8 is connected to the flushing and suction pipe 1. A movable filter plate 9 is also provided on the inner surface of the filter cylinder 8. The movable filter plate 9 can rotate on the inner surface of the filter cylinder 8 and can block or move away from the first port.

[0058] A rotating rod 12 is rotatably connected to the inner surface of the filter cylinder 8. The surface of the rotating rod 12 is fixedly connected to the movable filter plate 9 through a connecting frame 11. A transmission wheel 6 is fixedly connected to one end of the rotating rod 12 and the rotating shaft 41. A transmission belt 7 is sleeved on the surface of the two sets of transmission wheels 6.

[0059] When the switching mechanism 4 controls the solenoid valve 3 on the liquid suction port of the three-way pipe 2 to open, the movable filter plate 9 is misaligned with the first port. When the switching mechanism 4 controls the solenoid valve 3 on the liquid flushing port of the three-way pipe 2 to open, the movable filter plate 9 blocks the first port.

[0060] In this embodiment, during the aspiration of surgical fluid, tissue fragments in the surgical fluid will flow with the surgical fluid. When these tissue fragments pass through the solenoid valve body 3, they are easy to adhere to the solenoid valve body 3, causing blockage or even damage to the solenoid valve body 3, affecting the service life of the solenoid valve body 3. In this embodiment, by setting a fixed filter plate 10, the tissue fragments in the surgical fluid can be filtered out during the aspiration of surgical fluid, preventing them from blocking the solenoid valve body 3 and causing damage to it.

[0061] By setting the movable filter plate 9, when the push plate 47 is pushed to switch the switching mechanism 4 to the flushing function, the rotating shaft 41 rotates with the push plate 47, thereby driving the transmission wheel 6, the transmission belt 7 and the rotating rod 12 to rotate. Therefore, the movable filter plate 9 can be moved to the first port. In this way, during flushing, the flushing fluid will disperse the tissue fragments on the fixed filter plate 10. By setting the movable filter plate 9 to block the first port, these tissue fragments can be prevented from flowing back into the patient's body through the first port.

[0062] In actual use, the filter cartridge 8 can be equipped with an openable cover, and the cover and the filter cartridge 8 can be assembled by threaded connection. By unscrewing the cover, the movable filter plate 9 and the fixed filter plate 10 inside the filter cartridge 8 can be cleaned. The cleaning frequency of the movable filter plate 9 and the fixed filter plate 10 can be determined according to the specific usage.

[0063] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0064] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
