Description

Technical Field

[0001] The present invention relates to the field of medical technology, and more particularly to a multifunctional integrated neurosurgery suction device. Background Art

[0002] During surgery or before closing the incision at the end of surgery, the surgeon should fully flush the surgical field or related body cavity, which not only helps to maintain a clear surgical field of view, but also can remove residual necrotic tissue, blood clots, contaminated or infected fluids, and detached tumor cells from the surgical wound to the maximum extent, thereby reducing infection at the surgical site, the occurrence of residual abscesses, or implantation metastasis in patients with malignant tumors.

[0003] In the actual operation, the operation site needs to be constantly flushed and the waste liquid needs to be constantly sucked. This requires a flushing instrument and a suction instrument. The two instruments are constantly replaced during use, which is quite troublesome to coordinate during the operation and wastes operation time. More importantly, the flushing fluid may flow to the non-surgical site because it cannot be sucked immediately, causing infection to the tissue. What is more troublesome is that in minimally invasive surgery, it is almost impossible to constantly replace and use them, which brings great inconvenience to the operation. At present, in order to avoid frequent replacement of flushing instruments and suction instruments, the prior art connects a section of soft rubber drainage tube to the suction tube, and keeps the suction device in an open state during operation. The operator controls the suction switch by folding the rubber drainage tube. Although this method reduces the difficulty of operation, the suction tube is always placed at the operation site during the operation, which is easy to cause compression and even damage to the local tissue, which is not conducive to the safety of the operation. For this reason, a multifunctional integrated neurosurgery suction device is proposed. Summary of the invention

[0043] like Figures 1 to 9 As shown, an embodiment of the present invention provides a multifunctional integrated neurosurgery suction device, comprising a flushing and suction integrated tube 1, a three-way tube 2 and a solenoid valve body 3, wherein the three groups of ports of the three-way tube 2 are respectively set as a common port, a liquid suction port and a flushing port, one end of the flushing and suction integrated tube 1 is connected to the common port of the three-way tube 2, and the solenoid valve body 3 is arranged in the liquid suction port and the flushing port of the three-way tube 2;

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

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

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

[0047] Part of the three-way pipe 2 and the electromagnetic valve body 3 are both located inside the shell 42 , and the suction port and the flushing port of the flushing and suction integrated pipe 1 and the three-way pipe 2 are both extended to the outside of the shell 42 .

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

[0049] The surgical aspirator in this embodiment has the functions of both flushing and suction, and the switching of the two functions is achieved through the switching mechanism 4. Specifically, in actual use, the operator can hold the shell 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 groups of movable conductive sheets 43 can alternately contact with the corresponding fixed conductive sheets 44, and the two groups of control switches formed by the movable conductive sheets 43 and the fixed conductive sheets 44 can be alternately started, so that the solenoid valve body 3 of the suction port of the three-way tube 2 and the flushing port are alternately opened, thereby realizing the switching of the flushing function and the suction function.

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

[0051] The cutting mechanism 5 includes a vertical slot 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 member. The outer cylinder 56 is fixedly connected to the push plate 47 and is arranged in the radial direction of the rotating shaft 41, and the telescopic plate 55 is cooperatively installed inside the outer cylinder 56 and forms a moving 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, and the other end of the pull rope 54 is fixedly connected to the slider 52. The vertical slot 51 is opened inside the push plate 47, and the slider 52 is cooperatively installed inside the vertical slot 51 to form a moving 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 driven to move, and a return member is arranged between the telescopic plate 55 and the outer cylinder 56.

[0052] In this embodiment, by providing a cutting mechanism 5, the surgical suction device can have only the corresponding flushing or suction function to meet the use needs in different surgical situations. Specifically, when only the flushing function is needed, the pressure plate 59 corresponding to the suction function can be pressed to drive the connecting rod 53 and the slider 52 to move downward along the vertical groove 51. The slider 52 can thereby drive the telescopic plate 55 and the movable conductive sheet 43 corresponding to the suction 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 suction function. At this time, pushing the push plate 47 can only make the movable conductive sheet 43 controlling the flushing function contact with 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 flushing function repeatedly separate and contact with the fixed conductive sheet 44, thereby achieving the effect of point flushing; similarly, when only the suction function is needed, the pressure plate 59 corresponding to the flushing function can be pressed.

[0053] The return member includes guide rods 58 fixedly mounted on both sides of 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 surfaces of the guide rods 58. When the telescopic plate 55 moves, the springs 57 are extended or compressed.

[0054] In this embodiment, the recovery of the telescopic plate 55 and the movable conductive sheet 43 is achieved by the spring 57. Specifically, when the pressing plate 59 is pressed to drive the telescopic plate 55 and the movable conductive sheet 43 to move, the spring 57 sleeved on the surface of the guide rod 58 is compressed, thereby accumulating elastic potential energy. When the pressing 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, the recovery member may also use other moving mechanisms with a reset function, such as using a cylinder to reset the telescopic plate 55 and the movable conductive sheet 43 according to changes in air pressure, which will not be elaborated here.

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

[0056] During the use of this embodiment, the integrated flushing and suction tube 1 will be worn out after long-term use and needs to be replaced. In this embodiment, the integrated flushing and suction tube 1 is assembled by threads at a fixed end and a movable end. When replacing, since the movable end of the integrated flushing and suction tube 1 is in direct contact with the surgical site, the degree of wear will be relatively high. Therefore, the movable end of the integrated flushing and suction tube 1 can be directly replaced.

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

[0058] The inner surface of the filter cartridge 8 is rotatably connected to a rotating rod 12, and the surface of the rotating rod 12 is fixedly connected to the movable filter plate 9 by means of a connecting frame 11. The rotating rod 12 and one end of the rotating shaft 41 are both fixedly connected to a transmission wheel 6, and 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 electromagnetic valve body 3 on the 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 electromagnetic valve body 3 on the flushing port of the three-way pipe 2 to open, the movable filter plate 9 blocks the first port.

[0060] In the process of sucking surgical effusion in the present embodiment, tissue fragments in the surgical effusion will flow with the surgical effusion. When these tissue fragments pass through the solenoid valve body 3, they are easy to adhere to the solenoid valve body 3, causing the solenoid valve body 3 to be blocked or even damaged, thereby affecting the service life of the solenoid valve body 3. In the present embodiment, by setting a fixed filter plate 10, when sucking surgical effusion, tissue fragments in the surgical effusion can be filtered out to prevent them from clogging the solenoid valve body 3 and causing damage to it.

[0061] By setting up the movable filter plate 9, in the process of pushing the push plate 47 to switch the switching mechanism 4 to the flushing function, the rotating shaft 41 rotates following the push plate 47, thereby driving the transmission wheel 6, the transmission belt 7 and the rotating rod 12 to rotate, so that the movable filter plate 9 can be driven to transfer to the first port. In this way, during flushing, the flushing liquid will disperse the tissue fragments on the fixed filter plate 10. By setting up 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 provided with a cover body that can be opened and closed, and the assembly method of the cover body and the filter cartridge 8 can be a threaded connection. By unscrewing the cover body, the movable filter plate 9 and the fixed filter plate 10 inside the filter cartridge 8 can be cleaned, wherein the cleaning frequency of the movable filter plate 9 and the fixed filter plate 10 can be determined according to the specific usage conditions.

[0063] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
