Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a suction apparatus with a flushing function. Background Art

[0002] In abdominal surgery or laparoscopic surgery, suction drainage and flushing are two important operative steps, which contribute to improving the safety and effectiveness of the surgery and reducing the risk of postoperative complications. The main purpose of suction drainage is to maintain a clear operative field. During the surgery, there may be blood or body fluids accumulating in the operative area, which will obstruct the doctor's vision and affect the surgical operation. Through suction, the doctor can clean up these liquids and keep the operative field open and clear. In addition, suction can also be used to remove diseased tissues or foreign bodies. The main function of flushing is to clean the operative area.

[0003] Currently, the suction drainage operation is achieved by a suction apparatus using the negative pressure principle to perform the suction function, helping medical staff to remove excess liquids, blood and air from the operative area to ensure the smooth progress of the surgery. The flushing operation usually uses physiological saline as the flushing fluid, and a syringe or a flushing device is used to inject the flushing fluid into the operative area to clean the wound surface and wash away blood clots or tissue fragments. In this way, at least two pipeline systems of the suction apparatus and the flushing device need to be arranged in the operative area, increasing the complexity of the preoperative preparation work.

[0004] After retrieval, a suction apparatus with a flushing function is disclosed in the Chinese patent document CN209060146U. The suction apparatus includes a suction head, a pipeline device and a tail-end device. The pipeline device includes a suction pipe and a flushing pipe arranged in parallel. After the suction head and part of the pipeline device are inserted into the patient's body, the accumulated fluid generated during the surgery can be discharged from the patient's body through the suction pipe, and the cleaning fluid and the like required for the surgery can be injected into the patient's body through the flushing pipe.

[0005] However, during the use of the above suction apparatus in abdominal surgery and laparoscopic surgery, medical staff need to select different suction heads according to different use scenarios to meet the corresponding suction requirements. For example, a small suction head is selected to meet the delicate suction requirements in relatively delicate scenarios; another example is that a suction head with a large aperture is selected to ensure smooth drainage in the suction area in scenarios with a large amount of exudate and bleeding. In this way, on the one hand, replacing the suction head during the surgery easily affects the surgical process; on the other hand, in some suction scenario requirements, even if the suction head with a large aperture is replaced, the suction apparatus will cause a suction dead angle due to its own position relationship, thereby affecting the suction effect during the surgery. Summary of the Invention

[0006] The purpose of the present utility model is to provide a suction head structure during open surgery and laparoscopic surgery, so as to achieve suction drainage and irrigation, and improve the suction efficiency.

[0007] To achieve the above purpose, the present utility model adopts the following scheme:

[0008] A suction device with a flushing function includes a suction head and a tube body for connecting a negative pressure device;

[0009] An aspiration channel is provided inside the tube body, and a card slot for matching the suction head is provided at the end of the aspiration channel;

[0010] The installation end of the suction head is embedded in the card slot. The suction end of the suction head is provided with a drainage hole for communicating with the suction channel. A groove is provided on the side wall of the suction head, and the groove extends along the axial direction of the suction head. The groove is connected to the drainage hole;

[0011] The suction end of the suction head is also provided with a flushing hole, which is separated from the drainage hole. The flushing hole extends along the axial direction of the suction head into the suction channel.

[0012] Among them, the flushing hole is used to connect a flushing pipeline. The flushing pipeline is connected to the flushing hole from the inside of the suction channel, realizing the flushing function of the suction head, effectively improving the coupling of the suction pipeline and the flushing pipeline.

[0013] Compared with the prior art, the suction device with a flushing function provided by the present utility model has the following substantial features and improvements: By arranging multiple grooves on the side wall of the suction head, the suction area of the suction head is not limited to the suction of the drainage hole. The grooves form an all-round suction area in the radial direction of the suction head, greatly increasing the effective suction area, reducing the risk of the suction head being completely blocked, and improving the suction efficiency. At the same time, by using the flushing hole provided on the suction head, the flushing pipeline is guided through the suction channel to be connected to the flushing hole, making the flushing pipeline and the suction pipeline form a coupling, improving the coupling of the suction pipeline and the flushing pipeline, avoiding the entanglement between the pipelines, and enhancing the operation stability of negative pressure suction and flushing.

[0019] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0020] As Figures 1 - 4 shown, in the embodiment of the present utility model, a suction device with a flushing function is proposed, aiming to achieve suction drainage and flushing during open surgery and laparoscopic surgery, and improve the suction efficiency.

[0021] A suction device with a flushing function proposed in the embodiment of the present utility model utilizes the flushing holes provided on the suction head, and guides the flushing tube to be connected to the flushing holes through the suction channel, so that the flushing pipeline and the suction pipeline are coupled, improving the coupling of the suction pipeline and the flushing pipeline, avoiding the entanglement between the pipelines, and enhancing the operation stability of negative pressure suction and flushing.

[0022] As Figure 1 shown, a suction device with a flushing function includes a suction head 2 and a pipe body 1 for connecting a negative pressure device. A suction channel is provided inside the pipe body 1. A card slot for matching the suction head 2 is provided at the end of the suction channel.

[0023] As Figure 2 shown, the mounting end 21 of the suction head 2 is embedded in the card slot. For example, the mounting end 21 of the suction head 2 and the card slot are in interference fit. Such a setting is beneficial to ensuring the strength between the suction head 2 and the pipe body 1, enhancing the sealing performance between the mounting end 21 and the card slot, and ensuring the transmission of negative pressure between the suction head 2 and the pipe body 1.

[0024] The suction end 22 of the suction head 2 is provided with a drainage hole 24 for communicating with the suction channel. A groove 23 for increasing the suction area is provided on the side wall of the suction head 2. The groove 23 extends along the axial direction of the suction head 2. The groove 23 is connected to the drainage hole 24. A plurality of grooves 23 are arranged in a circular array along the center line of the suction head 2 on the side wall of the suction head 2. For example, the length of the groove 23 extending along the axial direction of the suction head 2 is 3 cm - 4 cm to ensure that the suction head 2 has an effective suction length of 3 cm. The aperture of the drainage hole 24 is 5 mm - 6 mm.

[0025] Among them, the number of the grooves 23 is selected according to the diameter of the suction head 2 and the actual required suction volume, and an appropriate number of grooves is chosen. The number of the grooves 23 is preferably 3 - 8. For example, as Figure 3 Combined with Figure 4 shown, six grooves 23 are provided on the side wall of the suction head 2, and the six grooves 23 are arranged in a circular array along the center line of the suction head 2. With such an arrangement, it is beneficial to further increase the effective area for the suction head 2 to perform suction, and avoid suction dead angles.

[0026] As Figure 4 shown, a flushing hole 26 is further provided at the suction end 22 of the suction head 2. The flushing hole 26 is separated from the drainage hole 24. The flushing hole 26 extends along the axial direction of the suction head 2 into the suction channel. The flushing hole 26 is used to connect a flushing pipeline, and the flushing pipeline is connected to the flushing hole 26 from the inside of the suction channel, realizing the flushing function of the suction head 2, and effectively improving the coupling of the suction pipeline and the flushing pipeline. For example, the aperture of the flushing hole 26 is 1 mm - 2 mm.

[0027] As Figure 3 shown, the grooves 23 are arranged in a spiral pattern on the side wall of the suction head 2. With such an arrangement, it is beneficial for the grooves 23 to form an all-round suction area in the radial direction of the suction head 2, greatly reducing the probability of the solid or viscous colloid blocking the suction head 2, and being more suitable for the scenarios of a large amount of exudate and bleeding during laparotomy, and further improving the suction efficiency of the suction head 2.

[0028] As Figure 1 shown, a handheld part 11 for medical staff to hold is provided on the side wall of the pipe body 1. With such an arrangement, it is convenient for medical staff to hold the pipe body 1, and then drive the suction head 2 to perform suction operation, further reducing the operation difficulty.

[0029] As Figure 2 shown, a bending section 12 is provided between the clamping groove and the handheld part 11. With such an arrangement, the bending section 12 is used to adjust the suction direction of the suction end 22 of the suction head 2, and by adjusting the bending angle of the bending section 12, the suction direction of the suction head 2 can be adjusted.

[0030] As Figure 3 shown, a rounded corner 25 is provided at the suction end 22 of the suction head 2. With such an arrangement, the rounded corner 25 is used to protect the tissues in the abdominal cavity, and avoid the suction end 22 of the suction head 2 scratching the tissues in the abdominal cavity.

[0031] When the suction device with a flushing function proposed in the embodiment of the present utility model is in use, by arranging a plurality of grooves 23 on the side wall of the suction head 2, the suction area is not limited to the top opening, and medical staff encounter different usage scenarios during laparotomy, and there is no need to replace the suction head 2 to meet the corresponding suction requirements.

[0032] For example, in a relatively delicate scenario, the position of the suction head 2 is adjusted, and only the drainage holes 24 at the end of the suction head 2 are directly used for suction; in a scenario with a large amount of exudate and bleeding, the multiple grooves 23 cooperate with the drainage holes 24 to ensure smooth drainage in the suction area. The entire 3 cm at the head end of the suction head 2 is an effective suction area in all directions, greatly increasing the effective suction area. Moreover, the spiral design ensures that the six grooves 23 do not cause suction dead zones due to their positions, improving the suction efficiency. The design of the six grooves also reduces the probability that the suction is blocked and affects the progress of the operation.

[0033] In addition, the flushing holes 26 provided on the suction head 2 are connected to the flushing pipe through the suction channel to guide the flushing pipe to be connected to the flushing holes 26, enabling the flushing pipeline and the suction pipeline to form a coupling, improving the coupling of the suction pipeline and the flushing pipeline, avoiding entanglement between the pipelines, and enhancing the operational stability of negative pressure suction and flushing.

[0034] The utility model is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the utility model can also have other implementation manners. For those skilled in the art, any technical solutions formed by making any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the utility model shall be included within the protection scope of the utility model.
