Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a multi-channel cannula kit with flushing and suction functions. Background Art

[0002] Abdominal surgery and laparoscopic surgery have become important means for treating various abdominal diseases. In these surgeries, suction drainage and flushing are indispensable key steps, which play a significant role in improving the safety and effectiveness of the surgery and reducing the risk of postoperative complications. The suction drainage operation is to use a suction device to remove excess fluid, blood, and air in the surgical area by the principle of negative pressure, ensuring the smooth progress of the surgical process. The flushing operation usually uses normal saline as the flushing fluid, and injects the flushing fluid into the surgical area through a syringe or a special flushing device to clean the wound surface and wash away blood clots or tissue fragments.

[0003] Among them, the main purpose of suction drainage is to maintain a clear surgical field of view. By suction, doctors can clean up these fluids and keep the surgical field open and clear. The main function of flushing is to clean the surgical area. To ensure the smooth progress of the surgery, at least two pipeline systems need to be arranged in the surgical operation area: one for suction drainage and the other for flushing. Although this setting increases the complexity of the surgical operation, it is an important measure to ensure the surgical quality and patient safety. The reasonable layout and use of the suction device and the flushing device are crucial for maintaining a clear surgical field of view and a clean surgical area.

[0004] However, arranging two pipeline systems for the suction device and the flushing device in the surgical operation area affects the surgical operation space. In the actual use process of the existing suction and flushing pipelines, they still do not break away from the design of the double-pipeline parallel structure, and the tube body is used to integrate the suction cavity and the flushing cavity. The flushing cavity occupies a part of the cross-section of the tube body, which is likely to affect the actual suction efficiency of the cannula, and further affects the surgical operation process. Summary of the Invention

[0005] The purpose of the utility model is to provide a cannula structure during the implementation of abdominal surgery and laparoscopic surgery, so as to improve the coupling of the suction pipeline and the flushing pipeline and enhance the operation stability of negative pressure suction and flushing.

[0006] To achieve the above purpose, the utility model adopts the following scheme:

[0007] A multi-channel cannula kit with flushing and suction functions, comprising

[0008] Connecting pipe, a diversion cavity is arranged inside the connecting pipe, a support member is arranged in the diversion cavity, the support member is connected to the inner wall of the connecting pipe, dividing the diversion cavity into multiple channels, and a first drainage groove is arranged on the side wall of the suction part of the connecting pipe, and the first drainage groove is connected to the channels;

[0009] Adjusting pipe, the adjusting pipe is sleeved on the suction part of the connecting pipe, the adjusting pipe rotates around the axis of the connecting pipe, and a second drainage groove corresponding to the first drainage groove is arranged on the side wall of the adjusting pipe, and the adjusting pipe has an open position and a closed position on the connecting pipe;

[0010] When the adjusting pipe is in the open position, the first drainage groove and the second drainage groove completely coincide, and the adjusting pipe and the connecting pipe form a drainage pipeline;

[0011] When the adjusting pipe is in the closed position, the side wall of the adjusting pipe forms a seal for the first drainage groove, and the adjusting pipe and the connecting pipe form a flushing pipeline.

[0012] Among them, the support member can provide sufficient internal support for the connecting pipe, maintaining the shape and function of the connecting pipe, and remaining stable even under negative pressure.

[0013] Preferably, the support member is a cross bar, the cross bar extends along the axial direction of the connecting pipe, and the diversion cavity is divided into 4 channels.

[0015] Preferably, the first drainage grooves are arranged in a circular pattern on the side wall of the connecting pipe around the axis of the connecting pipe. With this arrangement, when the adjusting pipe and the connecting pipe form a drainage pipeline, it is beneficial to form an annular suction area near the wound, further improving the drainage effect and the suction efficiency.

[0016] Preferably, both the first drainage groove and the second drainage groove are rectangular grooves.

[0017] Preferably, a sealing structure is arranged between the adjusting pipe and the connecting pipe, and the sealing structure is located at the end of the adjusting pipe. With this arrangement, the sealing structure is used to improve the sealing performance at the end of the adjusting pipe.

By rotating the adjusting pipe, the functions can be easily switched, enabling the operator to change the functions of the cannula through a simple rotating action without complex operation steps, simplifying the surgical process, improving the flexibility and efficiency of surgical operations. At the same time, since the cannula kit integrates the flushing and suction functions, the number of times of replacing different instruments during the operation is reduced, the surgical complexity and potential operation risks are lowered. Moreover, the coupling of the suction pipeline and the flushing pipeline is improved, and the support member can provide sufficient internal support for the connecting pipe to maintain the shape and function of the connecting pipe, remaining stable even under the action of negative pressure, thus enhancing the operation stability of negative pressure suction and flushing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0027] As Figures 1-5As shown in the figure, in the embodiment of the present utility model, a multi-channel cannula kit with flushing and suction functions is proposed, aiming to improve the coupling of the suction pipeline and the flushing pipeline during abdominal surgery and laparoscopic surgery, and enhance the operational stability of negative pressure suction and flushing.

[0028] The multi-channel cannula kit with flushing and suction functions proposed in the embodiment of the present utility model realizes the two functions of flushing and suction in abdominal surgery and laparoscopic surgery through the cannula structure of the connecting pipe and the adjusting pipe. By rotating the adjusting pipe, the operator can change the function of the cannula through a simple rotation action, improving the flexibility and efficiency of surgical operations. At the same time, since the cannula kit integrates the flushing and suction functions, the number of times of replacing different instruments during the operation is reduced, the surgical complexity and potential operation risks are lowered. Moreover, the multi-channel cannula kit with flushing and suction functions improves the coupling of the suction pipeline and the flushing pipeline. The support member can provide sufficient internal support for the connecting pipe, maintain the shape and function of the connecting pipe, and remain stable even under negative pressure, enhancing the operational stability of negative pressure suction and flushing.

[0029] As Figure 1 shown in combination with Figure 2 the figure, a multi-channel cannula kit with flushing and suction functions includes a connecting pipe 1 and an adjusting pipe 2. A diversion cavity 4 is arranged inside the connecting pipe 1. A support member 5 is arranged in the diversion cavity 4. The support member 5 is connected to the inner wall of the connecting pipe 1, dividing the diversion cavity 4 into multiple channels. A first drainage groove 6 is arranged on the side wall of the suction part of the connecting pipe 1. The first drainage groove 6 is connected to the channels.

[0030] The adjusting pipe 2 is sleeved on the suction part of the connecting pipe 1. The adjusting pipe 2 rotates around the axis of the connecting pipe 1. A second drainage groove 7 corresponding to the first drainage groove 6 is arranged on the side wall of the adjusting pipe 2. The adjusting pipe 2 has an open position and a closed position on the connecting pipe 1.

[0031] As Figure 1 shown in the figure, when the adjusting pipe 2 is in the open position, the first drainage groove 6 and the second drainage groove 7 completely coincide, and the adjusting pipe 2 and the connecting pipe 1 form a drainage pipeline. The drainage pipeline uses the principle of negative pressure to remove excess liquid, blood, and air in the surgical area, ensuring the cleanliness of the surgical area, providing a clear vision for the doctor, and enabling more precise surgical operations.

[0032] As Figure 4As shown, the regulating tube 2 is in the closed position, the side wall of the regulating tube 2 closes the first drainage groove 6, and the regulating tube 2 and the connecting tube 1 form a flushing pipeline. Normal saline is used as the flushing liquid, and the flushing liquid is injected into the surgical area through the flushing pipeline by means of a syringe or a dedicated flushing device. Flushing not only helps to remove the pollutants generated during the operation, but also promotes the healing of the wound and reduces the possibility of postoperative infection.

[0033] Among them, a coupling joint 3 is connected to the connecting part of the connecting tube 1. One end of the coupling joint 3 is provided with an output port, and the other end of the coupling joint 3 is provided with a negative pressure suction port 8 and a flushing port 9. The output port is connected to the negative pressure suction port 8 and the flushing port 9 through a Y-shaped pipeline. With such a setting, it is convenient for the flushing tube and the suction tube to form a coupling, improving the coupling performance of the suction pipeline and the flushing pipeline and avoiding the entanglement between the pipelines.

[0034] For example, a solenoid valve is provided on the Y-shaped pipeline. With such a setting, the solenoid valve on the Y-shaped pipeline is used to control the flow of fluid (such as suction fluid or flushing fluid). It realizes the opening and closing of the valve through electromagnetic force, and further realizes the switching between the negative pressure suction and flushing functions.

[0035] As Figure 3 shown, the first drainage grooves 6 are arranged in a circular pattern on the side wall of the connecting tube 1 around the axis of the connecting tube 1. With such a setting, when the regulating tube 2 and the connecting tube 1 form a drainage pipeline, it is beneficial to form an annular suction area near the wound, further improving the drainage effect and the suction efficiency.

[0036] As Figure 2 shown, both the first drainage groove 6 and the second drainage groove 7 are rectangular grooves. The first drainage grooves 6 and the second drainage grooves 7 correspond to each other one by one.

[0037] In order to further improve the flushing effect of the multi-channel cannula kit, a sealing structure is provided between the regulating tube 2 and the connecting tube 1. The sealing structure is located at the end of the regulating tube 2. With such a setting, the sealing structure is used to improve the sealing performance of the end of the regulating tube 2. When the regulating tube 2 and the connecting tube 1 form a flushing pipeline, it is beneficial to prevent the flushing liquid from overflowing between the regulating tube 2 and the connecting tube 1, thereby ensuring the flushing effect.

[0038] For example, the sealing structure includes an annular sealing groove arranged on the side wall of the connecting tube 1, and a sealing ring is embedded in the annular sealing groove.

[0039] As Figure 3 shown, the support member 5 is a cross bar 10, the cross bar 10 extends along the axial direction of the connecting tube 1, and the diversion cavity 4 is divided into 4 channels. As Figure 5As shown, the support member 5 is a three-pronged star strip 11. The three-pronged star strip 11 extends along the axial direction of the connecting pipe 1, and the diversion cavity 4 is divided into three channels. The support member 5 can provide sufficient internal support for the connecting pipe 1, maintaining the shape and function of the connecting pipe 1, and remaining stable even under negative pressure, improving the operational stability of negative pressure suction and flushing.

[0040] When the multi-channel cannula kit with flushing and suction functions proposed in the embodiment of the present utility model is in use, according to the surgical needs, the rotation adjustment tube 2 is switched between the open position and the closed position to achieve the conversion of the suction and flushing functions.

[0041] When using the suction function: Rotate the adjustment tube 2 to the open position. At this time, the second drainage groove 7 of the adjustment tube 2 completely coincides with the first drainage groove 6 of the connecting pipe 1; Connect the suction device (such as a suction pump), turn on the suction device, and suck out the liquid and tissue debris in the abdominal cavity through the drainage pipeline formed by the first drainage groove 6 and the second drainage groove 7.

[0042] When using the flushing function: Rotate the adjustment tube 2 to the closed position. At this time, the side wall of the adjustment tube 2 closes the first drainage groove 6; Connect the flushing device (such as a flushing pump), turn on the flushing device, and inject the flushing liquid into the abdominal cavity through the diversion cavity 4 inside the connecting pipe 1 for flushing.

[0043] The present utility model is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present 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 present utility model shall be included within the protection scope of the present utility model.
