DETAILED DESCRIPTION

[0021] The specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0022] As Figures 1-3 shown in the utility model embodiment, a suction device with electrocoagulation hemostasis is proposed, aiming to provide auxiliary guidance for the positioning and processing of bleeding points in the process of intraoperative hemostasis and cleaning of the surgical area, reduce the risk of ineffective electrocoagulation, and improve the suction efficiency.

[0023] The suction device with electrocoagulation hemostasis proposed in the utility model embodiment can effectively balance the suction pressure, improve the suction efficiency, ensure a more stable and continuous suction process, and reduce the risk of excessive suction by setting a support 4 inside the suction tube 1 to divide the drainage cavity into multiple drainage channels 5, and setting a through hole 6 on the side wall of the suction tube 1, so that each drainage channel 5 is connected to the through hole 6. The design of the suction device with electrocoagulation hemostasis facilitates the division of the area drained by the end face of the suction end of the suction tube 1 when operating on the hemostasis area 7, which is conducive to positioning the approximate direction of the bleeding point 8 according to the amount of drainage in each drainage channel 5, achieving auxiliary guidance for the positioning and processing of the bleeding point 8, and reducing the risk of ineffective electrocoagulation.

[0024] As Figure 1 shown, a suction device with electrocoagulation hemostasis includes a suction tube 1 for connecting a negative pressure suction device, and an electrode head 2 for electrocoagulation hemostasis.

[0025] As Figure 1 shown in combination Figure 2 , the suction end of the suction tube 1 is provided with a suction effective area 3. The inside of the suction tube 1 is provided with a drainage cavity. The drainage cavity is provided with a support 4. The support 4 is connected to the inner wall of the suction tube 1, dividing the drainage cavity into multiple drainage channels 5. The side wall of the suction tube 1 is provided with a through hole 6. The through hole 6 is located in the suction effective area 3. The through hole 6 is connected to the drainage channel 5, respectively. For example, the number of suction channels is 2-N. The number of suction channels is preferably 4, which is applied to the hemostasis scene of laparoscopic minimally invasive surgery. The number of suction channels is preferably 6, which is applied to the hemostasis scene of open surgery.

[0026] As Figure 1 shown, the electrode head 2 is arranged on the end face of the suction end of the suction tube 1. The electrode head 2 is installed on the support 4. The electrode head 2 protrudes from the end face of the suction end of the suction tube 1.

[0027] In order to further reduce the difficulty of positioning and guiding, the suction tube 1 is a transparent tube. In this way, the transparent tube facilitates the operator to observe the flow of liquid in each drainage channel 5 in real time during the suction process, and the operator can judge the suction effect in time by visually monitoring the flow state of the liquid in the suction tube 1, which helps to quickly adjust the suction degree, ensures the smooth progress of the suction process, further facilitates the observation of the color depth of the suction liquid, and reduces the difficulty of forming positioning on the approximate direction of the bleeding point 8.

[0028] For example, as shown in Figure 2 , the support 4 is a cross bar. The cross bar extends along the axial direction of the suction tube 1. The drainage cavity is divided into four drainage channels 5. In this way, the cross bar design provides uniform support, making the internal structure of the suction tube 1 more stable and durable, reducing the risk of deformation or collapse of the suction tube 1 during use, and ensuring the long-term stable working performance of the equipment. On the other hand, the four drainage channels 5 separated by the cross bar correspond to the four quadrants on the plane coordinate system, which is conducive to providing more accurate and stable positioning and guiding for the direction of the bleeding point 8.

[0029] The support 4 extends along the axial direction of the suction tube 1, and the length of the support 4 is greater than 1 / 3 of the length of the suction tube 1 and less than 1 / 2 of the length of the suction tube 1. In this way, it is conducive to reducing the manufacturing cost of the drainage tube.

[0030] As shown in Figure 3 , taking the position of the axis of the drainage tube as the origin, the cross bar is two mutually perpendicular coordinate axes, which divides the drainage cavity into a first channel 10, a second channel 11, a third channel 12 and a fourth channel 13, which correspond to the four quadrants of the plane coordinate system. In the hemostasis area 7, the bleeding point 8 is located at the lower right of the drainage tube, that is, the bleeding point 8 is located in the fourth quadrant. In the actual use of the drainage tube, the operator can obviously observe that the color of the liquid in the fourth channel 13 is deeper than that in the other three channels. In this way, the operator will adjust the position of the drainage tube in the direction of the fourth quadrant, such as the guide direction 9 shown in Figure 3 , so that the electrode head 2 is closer to the hemostasis point, thereby playing an auxiliary positioning role for electrocoagulation hemostasis.

[0031] According to some preferred embodiments of the present application, the electrode head 2 is coaxially arranged with the suction tube 1. In this way, the centralization and unification of electrocoagulation hemostasis and suction function are ensured, the operator can more accurately control the position of the electrode head 2, improve the effect and accuracy of electrocoagulation hemostasis, reduce the risk of misoperation, so that the operator can operate more naturally when using, without frequent adjustment of the position or angle of the hand, reducing the complexity of surgical operation, improving the efficiency of operation.

[0032] In order to further improve the stability of the electrode head 2, the support 4 is provided with a wire hole for threading the cable. The wire hole is arranged along the axial direction of the suction tube 1. The electrode head 2 is embedded in the wire hole. In this way, by providing the wire hole on the support 4, the cable of the electrode head 2 can be orderly arranged along the axial direction of the suction tube 1, avoiding the cable in the drainage cavity in disorder, embedding the electrode head 2 in the wire hole can ensure its stability during operation, avoiding the electrode head 2 position offset caused by vibration or movement during operation, thereby ensuring the accuracy and consistency of the electrocoagulation hemostasis.

[0033] As shown in Figure 1 The through hole 6 is arranged in a linear array along the axial direction of the suction tube 1, forming a negative pressure balancing unit. The negative pressure balancing unit is arranged in a circular shape on the side wall of the suction tube 1 along the axial line of the suction tube 1. In this way, the formation of the negative pressure balancing unit can more effectively balance and stabilize the negative pressure in the suction tube 1, making the suction process more efficient, which helps to quickly remove the liquid and debris in the surgical area, improves the operation efficiency, and the uniformly distributed through holes 6 can reduce the direct adsorption and damage of the suction tube 1 to the surrounding tissue, gently suctioning the liquid and blood clots, reducing the trauma to the patient's tissue during the operation, and promoting rapid recovery after the operation.

[0034] The suction device with electrocoagulation hemostasis proposed in the embodiment of the utility model uses when, the negative pressure is produced in the suction tube 1, and through the multiple drainage channels 5, the negative pressure can form a uniform suction force field in the surgical area. Under the action of negative pressure, the surrounding blood and tissue fluid will be guided by the drainage channel 5. Especially the liquid around the bleeding point 8, will be quickly concentrated to the center of the suction tube 1 under the action of negative pressure. This guiding action helps the surgical personnel to quickly determine the position of the bleeding point 8. Once the position of the bleeding point 8 is determined, the electrode head 2 with electrocoagulation function can act on the bleeding point 8 accurately. Under the action of the electrode head 2, the bleeding is quickly stopped by electrocoagulation hemostasis.

[0035] 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 modification, equivalent replacement, improvement, etc. formed in the spirit and principles of the utility model should be included in the protection scope of the utility model.
