Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a tubing structure for use in endoscopic electrocoagulation devices. Background Technology
[0002] In surgical procedures, electrocoagulation forceps are commonly used instruments for hemostasis and tissue management. However, existing electrocoagulation forceps have significant shortcomings in practical applications. During surgery, they are generally required to absorb bodily fluids, tissue debris, blood, or to irrigate and inject saline solution, but these functions rely on external tubing. External tubing not only increases the complexity of the equipment but also requires multiple operators—one person operating the forceps while others handle the tubing-related actions. This reduces surgical efficiency, increases the risk of errors in coordination affecting accuracy, and may even disrupt the surgical procedure, increasing surgical risks. Therefore, there is an urgent need for an integrated and convenient electrocoagulation forceps design to solve the cumbersome operation caused by reliance on external tubing, thus meeting the demands of efficient and precise modern surgery.

[0017] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 As shown, a tubing structure for laparoscopic electrocoagulation instruments, belonging to the tubing structure for electrocoagulation forceps, includes an electrocoagulation body 1 and a fluid tubing 2.
[0018] Combination Figure 2 As shown, the electrocoagulation body 1 includes a pair of metal clamping members 11, which are fixedly installed at their roots. The clamping members 11 deform under force to complete the clamping action. In practical applications, the clamping members 11 are fixedly installed on the electrode base and connected to wires. The wires are connected to the electrocoagulation host. When energized, current flows through the metal clamping members 11. During the process of clamping tissue at the head of the clamping members 11, it can achieve rapid hemostasis and is used in delicate surgeries.
[0019] The laparoscopic electrocoagulation instrument (electrocoagulation forceps) in this application is mainly used in laparoscopic surgery. The user controls the electrocoagulation body 1 remotely. Therefore, the electrocoagulation body 1 is mounted on the extension shaft 3, and the end of the extension shaft 3 away from the electrocoagulation body 1 is also provided with a gripping operation part 4.
[0020] like Figure 2 As shown, the fluid line 2 passes through the extension shaft 3 and includes a counter-current line 22 and / or a forward-current line 21. One end of the fluid line 2 is fitted against the wall of the clamping member 11 and extends from the root of the clamping member 11 toward the head side. The end of the fluid line 2 away from the clamping member 11 is installed in the gripping operation part 4.
[0021] Specifically, the countercurrent conduit 22 is fitted to one end of the clamping member 11 for fluid intake, and the cocurrent conduit 21 is fitted to one end of the clamping member 11 for fluid outflow. The fluid in the cocurrent conduit 21 flows from the gripping operation part 4 to the clamping member 11 to realize the dripping operation, including rinsing or dripping physiological saline. The fluid in the countercurrent conduit 22 flows from the clamping member 11 to the gripping operation part 4 to realize the suction operation, including suctioning blood, other tissue fluids, smoke, or tissue debris. In this embodiment, each clamping member 11 is provided with both the cocurrent conduit 21 and the countercurrent conduit 22, so that the countercurrent conduit 22 or the cocurrent conduit 21 can be opened as needed during use.
[0022] The outer wall of the clamping member 11 is provided with a groove 12 for embedding the co-current pipe 21 and the counter-current pipe 22. The opening length of the groove 12 on the clamping member 11 is greater than the extension length of the fluid pipe 2 that fits against the clamping member 11, so as to ensure that the opening ends of the co-current pipe 21 and the counter-current pipe 22 can fully flow fluid.
[0023] The extension length of the countercurrent conduit 22 adhering to the clamping member 11 is not less than the extension length of the cocurrent conduit 21 adhering to the clamping member 11. That is, the countercurrent conduit 22 needs to be closer to the head of the clamping member 11, making it as close to the liquid surface as possible to facilitate liquid aspiration; while the cocurrent conduit 21 is mainly used for dripping, allowing the liquid to drip down along the clamping member 11, and its extension length can be less than the extension length of the countercurrent conduit 22. Figure 2 As shown, in this embodiment, the end of the countercurrent pipe 22 is closer to the head of the clamping member 11 than the cocurrent pipe 21.
[0024] As a further supplement, when both a forward flow channel 21 and a reverse flow channel 22 are distributed on a single clamping member 11, the reverse flow channel 22 can be placed on the wall surface opposite to the clamping members 11, and the forward flow channel 21 can be placed on the wall surface opposite to the clamping members 11. Since the wall surface opposite to the clamping members 11 is used to clamp tissue, and the reverse flow channel 22 is closer to the head of the clamping member 11, placing the reverse flow channel 22 on the wall surface opposite to the clamping members 11 would affect the clamping of the clamping member 11. Therefore, distributing the longer reverse flow channel 22 on the wall surface opposite to the clamping members 11 is more convenient for the user's operation. Of course, in other embodiments, the forward flow channel 21 or the reverse flow channel 22 can also be placed at other wall surface locations.
[0025] like Figure 3 , Figure 4 As shown, the width of the front end of the tank 12 gradually decreases along the direction of fluid flow, which not only satisfies the structural feature of the gradually tapering end of the clamping member 11, but also ensures that the liquid can be accurately dripped during the dripping process, making the operation more convenient.
[0026] The clamping member 11 is covered with an insulating layer 13, and at least part of the fluid conduit 2 is covered within the insulating layer 13. The head of the clamping member 11 is outside the space covered by the insulating layer 13. By covering it with the insulating layer 13, the current is conducted only between the heads of the clamping member 11. During electrocoagulation, the current flows from one head to the other, and only the tissue between the heads of the clamping member 11 is affected by the thermal effect of the current. Other tissues are less affected or unaffected, which can prevent the wound from expanding.
[0027] In order not to affect the suction operation of the countercurrent pipe 22, the end of the countercurrent pipe 22 that is attached to the clamping member 11 is also outside the space covered by the insulating layer 13; while the end of the co-current pipe 21 can be covered inside the insulating layer 13.
[0028] In order to achieve the connection and conduction of the fluid pipeline 2, the end of the fluid pipeline 2 away from the clamping member 11 is connected to the pipeline connector 41; in actual application scenarios, the pipeline connector 41 is installed on the gripping operation part 4.
[0029] Combination Figure 5 As shown, the fluid pipeline 2 includes a first pipeline 23 near one end of the clamping member 11 and a second pipeline 24 connected to the pipeline connector 41. In the application scenario, the second pipeline 24 has a larger diameter in order to connect with the pipeline connector 41, while the first pipeline 23 has a smaller diameter because the clamping member 11 is relatively slender. That is, the inner and outer diameters of the first pipeline 23 are smaller than the inner and outer diameters of the second pipeline 24, and a reducing pipeline 25 is connected between the first pipeline 23 and the second pipeline 24.
[0030] Since the fluid pipeline 2 includes a co-current pipeline 21 and a counter-current pipeline 22, the pipeline connector 41 includes a co-current connector 411 and a counter-current connector 412. The co-current pipeline 21 is used to connect to the co-current connector 411, and the counter-current pipeline 22 is used to connect to the counter-current connector 412. Furthermore, since each clamping member 11 is equipped with a counter-current pipeline 22 and a co-current pipeline 21, a tee connector 42 is installed on both the counter-current pipeline 22 and the co-current pipeline 21.
[0031] Combination Figure 1 As shown, a tee connector 42 is installed on the second pipeline 24. The second pipeline 24 includes a main pipe 241 and two branch pipes 242, which are connected by the tee connector 42. The first pipeline 23 is connected to the branch pipes 242 through a reducing pipe 25. The two first pipelines 23 connected to each pipeline connector 41 are respectively fitted with two clamping members 11.
[0032] For example, the main pipe 241 and branch pipe 242 connected by the tee connector 42 can have the same diameter or different diameters, but the diameter of the first pipe 23 is always smaller than the diameter of either the main pipe 241 or the branch pipe 242. In this embodiment, the diameters of the main pipe 241, the branch pipe 242, and the first pipe 23 gradually decrease.
[0033] In summary, this application integrates the fluid tubing 2 into the laparoscopic electrocoagulation instrument and sets it in conjunction with the clamping part 11 of the electrocoagulation body 1, achieving multi-functional integration. A single person can complete operations such as electrocoagulation, adsorption, and dripping without the need for multiple people to cooperate with external tubing, simplifying the surgical procedure, reducing manpower coordination costs, and improving operational efficiency and smoothness. At the same time, the optimized instrument layout makes the surgical area simpler, reduces the risk of tubing entanglement and interference, and allows the surgeon to focus on the operation. It also reduces the space occupied by the equipment and is suitable for complex surgical scenarios such as minimally invasive surgery.
