Description

Technical Field

[0001] This utility model relates to the field of electrode plugs, specifically a split-type surgical electrode plug structure. Background Technology

[0002] Currently, using electrodes for coagulation or cutting is the most efficient method of hemostasis in surgical procedures. The principle is to use high-frequency current to generate a thermal effect on the tissue, achieving tissue denaturation and coagulation. Because surgical electrodes have advantages such as minimal tissue damage and good hemostatic effect, they are now widely used in open surgery and various minimally invasive surgeries such as laparoscopic surgery.

[0003] In the process of developing this utility model, the inventors discovered that at least the following problems remain unresolved in the existing technology: In surgical procedures, the split-type surgical electrode plug mechanism is a core connecting component between surgical equipment such as high-frequency electrosurgical units and argon plasma coagulators and the electrodes. Its connection reliability, anti-misinsertion performance, and structural stability directly affect the transmission accuracy of surgical current and surgical safety. Currently, the split-type surgical electrode plug still faces the following technical challenges in clinical application and structural design, which restrict its effectiveness and safety. Therefore, a new technical solution needs to be designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a split surgical electrode plug structure to solve the technical problems of poor reliability, anti-misinsertion performance and structural stability of the current split surgical electrode plug mechanism during use.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a split surgical electrode plug structure is designed, including a main body cover and a secondary body cover. Three electrode pins are installed at one end of the main body cover. The distance between the first and second electrode pins from left to right is 1 / 2 of the distance between the first and second electrode pins from right to left. Each electrode pin is equipped with an anti-loosening mechanism.

[0006] Preferably, the anti-loosening mechanism includes a fixed shaft, one end of which is fixedly connected to the inner wall of the electrode insertion post, and three sleeve posts are fixedly connected to the outside of the fixed shaft.

[0007] Preferably, a spring is fixedly connected inside the sleeve post, and the other end of the spring abuts against one end of an anti-loosening post installed inside the sleeve post. The other end of the anti-loosening post is slidably connected to the inner wall of the through groove and extends to the outside of the electrode insertion post.

[0008] Preferably, three through slots are provided and are evenly distributed around the electrode post.

[0009] Preferably, one end of each of the three electrode posts is fitted over the outside of the limiting post, one end of the limiting post is fixedly connected to the inner surface of the main body cover, and a bolt mounting post is fixedly connected to the lower center of the main body cover.

[0010] Preferably, the sub-body cover has an insertion groove, the position of which corresponds to the position of the limiting post, and the lower middle part of the sub-body cover has a bolt insertion hole, the position of which corresponds to the position of the bolt mounting post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by designing the spacing between two electrode posts to be twice the spacing between the other two electrode posts, can prevent the electrode plug structure from being mistakenly inserted into an incompatible socket head, thus preventing damage and improving the protective effect of the electrode plug structure during use.

[0013] When the electrode post is inserted into the matching socket, the anti-loosening post slides inside the through groove and retracts into the sleeve post. During this process, the spring compresses the post, and conversely, the spring exerts a compressive force on the anti-loosening sleeve post, thus ensuring that the electrode post is firmly inserted into the matching socket. This prevents the plug structure from loosening and causing poor contact due to prolonged use of the matching socket, thereby improving the robustness of the split surgical electrode plug structure during use.

[0014] The design of the limiting post and the insertion slot can initially limit the position of the electrode insertion post, preventing the electrode insertion post from deviating during the closing of the main cover and the sub-cover, which helps to improve the convenience of the main cover and the sub-cover during installation.

[0015] When the main cover and the secondary cover overlap, the limiting post will be inserted into the insertion slot, thereby limiting the position of the three electrode posts and preventing the three electrode posts from deviating during use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A split-type surgical electrode plug structure, see [link to example]. Figures 1 to 3 It includes a main cover 1 and a secondary cover 11. Three electrode pins 12 are installed at one end of the main cover 1. The distance between the first and second electrode pins 12 from left to right is 1 / 2 of the distance between the first and second electrode pins 12 from right to left. This can prevent the electrode plug structure from being mistakenly inserted into an incompatible socket head, which would cause damage. This helps to improve the protective effect of the electrode plug structure during use.

[0022] Each electrode plug 12 is equipped with an anti-loosening mechanism, which includes a fixed shaft 13. One end of the fixed shaft 13 is fixedly connected to the inner wall of the electrode plug 12, and three sleeves 14 are fixedly connected to the outside of the fixed shaft 13. A spring 15 is fixedly connected inside the sleeve 14, and the other end of the spring 15 abuts against one end of an anti-loosening post 21 installed inside the sleeve 14. The other end of the anti-loosening post 21 is slidably connected to the inner wall of the through groove 16 and extends to the outside of the electrode plug 12. When the electrode plug 12 is inserted into the matching socket head, the anti-loosening post 21 slides inside the through groove 16 and retracts into the sleeve 14. During this process, the spring 15 will compress, and conversely, the spring 15 will exert a compressive force on the anti-loosening sleeve 14, so that the electrode plug 12 is firmly inserted into the matching socket head, avoiding the phenomenon of poor contact caused by the plug structure loosening between the plug structure and the matching socket head after long-term use. This helps to improve the firmness of the split surgical electrode plug structure during use.

[0023] For details, see Figure 3 There are three through slots 16, which are evenly distributed around the electrode insert 12. When the dog releases the loosening post, it slides inside the through slot 16, thereby achieving adaptive extrusion pressure adjustment.

[0024] Further, see Figure 1One end of each of the three electrode posts 12 is fitted onto the outside of the limiting post 17. One end of the limiting post 17 is fixedly connected to the inner surface of the main body cover 1. A bolt mounting post 18 is fixedly connected to the lower middle part of the main body cover 1. Installing the electrode posts 12 on the outside of the limiting post 17 can initially limit the position of the electrode posts 12, preventing the electrode posts 12 from deviating from their position during the closing process of the main body cover 1 and the sub-body cover 11. This helps to improve the ease of installation of the main body cover 1 and the sub-body cover 11.

[0025] It is worth noting that, see Figure 1 The sub-body cover 11 has an insertion groove 19, the position of which corresponds to the position of the limiting post 17. When the main body cover 1 and the sub-body cover 11 overlap, the limiting post 17 will be inserted into the insertion groove 19, thereby limiting the position of the three electrode posts 12 and preventing the three electrode posts 12 from deviating during use.

[0026] The lower middle part of the sub-body cover 11 has a bolt insertion hole 2. The position of the bolt insertion hole 2 corresponds to the position of the bolt mounting post 18. When the main body cover 1 and the sub-body cover 11 are overlapped and fixed, the threaded section of the bolt first passes through the bolt insertion hole 2 and then is tightened into the internal thread groove of the bolt mounting post 18, thereby achieving the purpose of installing and fixing the main body cover 1 and the sub-body cover 11.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
