Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an electrosurgical unit connection device adapted to different host devices. Background Technology

[0002] In high-frequency electrosurgery, bipolar electrocoagulation forceps or bipolar electrocoagulation clamps are commonly used surgical instruments. They are usually connected to the output port of the high-frequency electrosurgical unit via a connecting cable to obtain energy for tissue coagulation or cutting.

[0003] Currently, there are numerous brands of electrosurgical unit manufacturers on the market. Although most of these units adhere to certain industry standards, differences still exist in the design of their output jacks. The most significant issue lies in the inconsistent spacing between the bipolar jacks.

[0004] Existing electrosurgical unit connection devices typically adopt the following two structural forms:

[0005] One-piece injection-molded rigid plug: This is the most common type. During production, the manufacturer injection-moldes two conductive pins into a single piece of rigid plastic, fixing them at a specific spacing (e.g., 28.5mm or 22mm). The advantages of this structure are good overall integrity, stable insertion and removal feel, and ease of grip. However, its disadvantages are very obvious: extremely poor versatility. If the spacing of the sockets on the electrosurgical unit used in the hospital does not match this fixed spacing, the connector cannot be inserted, rendering the surgical instrument unusable. Hospitals then have to purchase different specifications of connectors for different brands of units, increasing procurement costs and inventory management complexity.

[0006] Separate independent plugs: These use two completely independent single-plug cables (like two separate banana plugs). While this design allows for adjustable spacing to fit all main units, it lacks overall integration. During surgery, the two independent cables are prone to tangling and becoming messy, and plugging and unplugging require two separate operations, increasing the workload for medical staff. A single, integrated plug is less convenient and standardized.

[0007] Therefore, the existing technology lacks an electric knife connection device that can flexibly adjust the pin spacing to adapt to different brands and hole spacings of electric knife main units, while maintaining good integrity and operational stability in normal use scenarios. Utility Model Content

[0008] To address the issue of existing pin spacing not being compatible with different brands and hole spacings of electrosurgical units, this application provides an electrosurgical connection device that is compatible with different units.

[0009] An electrosurgical unit connection device adaptable to different host computers, comprising:

[0010] A first connecting unit and a second connecting unit, both having conductive pins for insertion into the electrosurgical unit;

[0011] The connecting assembly includes an elastic bridging element, which is a deformable structure with elastic recovery capability, so that the first connecting unit and the second connecting unit can undergo relative displacement to change the spacing between the two conductive pins.

[0012] By adopting the above technical solution, this device utilizes the deformable characteristics of the elastic bridging component, so that the two conductive pins are no longer fixed at a single physical distance. This design allows for relative displacement between the first and second connecting units, thereby enabling free adjustment of the distance between the pins. Whether facing a standard hole-pitch electrosurgical unit or a special unit with a hole pitch that is too large or too small, this connection device can flexibly adapt, solving the problem of poor versatility of existing fixed plugs.

[0013] Optionally, the elastic bridging component is an elastic soft rubber structure, which has an elastic force that pushes the first connecting unit and the second connecting unit away from each other.

[0014] By adopting the above technical solution, the self-rebound force (pushing force) of the elastic soft rubber can cause the two connecting units to tend to open or maintain a certain tension in a natural state. This pushing force helps to provide lateral support when inserting into main units with different hole spacing, or to keep the two units separated when there is no external force constraint, making it easier for users to identify and perform insertion operations. It also increases the service life and fatigue resistance of the connectors.

[0015] Optionally, the connecting assembly further includes connecting rings, which are respectively fixed to both ends of the elastic bridging member, and the connecting rings are sleeved and fixed to the outer periphery of the first connecting unit and the second connecting unit.

[0016] By adopting the above technical solution, the design of the connecting ring achieves a stable connection between the elastic bridging component and the connecting unit. Compared with methods such as direct bonding, the sleeve structure is more robust, can withstand the pulling force during insertion and removal, prevents the elastic bridging component from falling off, and ensures the durability and safety of the product.

[0017] Optionally, the outer periphery of the connecting ring is provided with a first anti-slip texture.

[0018] By adopting the above technical solution, the first anti-slip texture increases the friction on the surface of the connecting ring. When medical staff hold this part for insertion and removal operations, or pinch this part when adjusting the spacing, the texture can play a significant anti-slip role, preventing operational errors caused by wet gloves or other reasons, and improving the operating feel.

[0019] Optionally, the elastic soft rubber structure is a sheet-like structure that is narrow in the middle and wide at both ends, and the ends of the elastic soft rubber structure are integrally formed with the connecting ring.

[0020] By adopting the above technical solution, the "narrow in the middle and wide at both ends" geometry concentrates deformation stress mainly in the narrower middle area, making deformation easier and more controllable, and avoiding stress concentration that could lead to breakage at the end joints. At the same time, the one-piece molding process not only simplifies the production process and reduces costs, but also eliminates seams, significantly enhancing the overall strength and sealing of the structure.

[0021] Optionally, the electrosurgical connection device further includes a detachable spacer housing, in which the first connecting unit and the second connecting unit are installed to maintain a relatively fixed positional relationship between the first connecting unit and the second connecting unit.

[0022] By adopting the above technical solution, a "dual-mode" usage concept is introduced. When facing a main unit with a standard pin spacing, the user can insert the connector into the spaced housing, transforming it into a standard, robust "integrated plug." This combination not only facilitates quick plugging and unplugging but also provides excellent mechanical stability after insertion, preventing loosening and protecting the internal flexible components from external scratches or pressure.

[0023] Optionally, the spaced housing includes a first housing and a second housing, which can be closed to enclose the first connecting unit and the second connecting unit within the spaced housing.

[0024] By adopting the above technical solution, the split-type housing design makes disassembly and assembly extremely simple and convenient. Users can quickly close the spaced-out housing to cover the plug without using tools, or disassemble it to restore the plug's free adjustment function. This design greatly improves the flexibility and efficiency of clinical operations.

[0025] Optionally, the first housing has a snap-fit ​​part on its inner side, and the second housing has a snap-fit ​​groove, wherein the snap-fit ​​part can be snapped into the snap-fit ​​groove.

[0026] By employing the above technical solution, the housing is closed using a snap-fit ​​mechanism, eliminating the need for screws or glue. Assembly and disassembly are quick and repeatable. The snap-fit ​​structure provides clear tactile feedback, ensuring the user confirms the housing is locked and guaranteeing structural integrity during use.

[0027] Optionally, the outer periphery of the spacer housing is provided with a second anti-slip texture.

[0028] By adopting the above technical solution, even after the fixed-distance housing is installed and it becomes an integrated plug, the second anti-slip texture on the outer periphery can still provide the necessary anti-slip function, making it convenient for users to apply force when plugging and unplugging the entire assembly, which is in line with ergonomic design.

[0029] Optionally, the first connecting unit and the second connecting unit are insulating shells.

[0030] By adopting the above technical solution, the parts other than the conductive pin have good electrical insulation performance, preventing electric shock accidents or short circuit risks caused by accidental contact, and ensuring the safety of medical staff and patients.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. This application breaks through the limitation of fixed spacing of traditional electrosurgical plugs by designing flexible bridging components, which can flexibly adapt to electrosurgical main units with different hole spacing specifications, and significantly improves the versatility and compatibility of the connection device;

[0033] 2. This application innovatively incorporates a fixed-distance housing structure, enabling the device to switch between a "free adjustment mode" and a "standard fixed mode." It offers flexibility when adapting to non-standard main units and stability and convenience when adapting to standard main units, thus balancing versatility and ease of operation.

[0034] 3. In terms of detailed design, such as anti-slip texture, the geometry of elastic soft rubber, and one-piece molding process, this application fully considers the safety, durability, and ease of operation for clinical use, thereby improving the user experience. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0041] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] This embodiment provides an electrosurgical unit connection device adapted to different host devices, used to connect electrosurgical instruments (such as bipolar electrocoagulation forceps, electrocoagulation clamps, etc.) to the electrosurgical unit. Figure 1 As shown, the electrosurgical unit connection device adapted to different hosts mainly includes a first connecting unit 10, a second connecting unit 20, and a connecting assembly 30.

[0043] Specifically, the first connecting unit 10 and the second connecting unit 20 are the terminal parts of the device used for electrical connection with the main unit. Both the first connecting unit 10 and the second connecting unit 20 have conductive pins 40 for insertion into the electrosurgical unit. The conductive pins 40 can be standard banana plugs, such as standard conductive metal rods with a diameter of 4mm, and their rear ends are usually connected to wires that extend rearward and converge to connect to the surgical instrument end.

[0044] The connecting component 30 includes an elastic bridging element 31, which is a deformable structure with elastic recovery capability, connecting the first connecting unit 10 and the second connecting unit 20. Through the deformable nature of the elastic bridging element 31, the first connecting unit 10 and the second connecting unit 20 are no longer constrained to a rigid fixed position, but can undergo relative displacement. This relative displacement allows the user to manually pull apart or compress the distance between the first connecting unit 10 and the second connecting unit 20 according to the actual hole spacing of the target electrosurgical unit, thereby changing the spacing between the two conductive pins 40. For example, when encountering an electrosurgical unit with a wide hole spacing, the elastic bridging element 31, through tensile or bending deformation, causes the two conductive pins 40 to separate outwards; when encountering an electrosurgical unit with a narrow hole spacing, it causes the two conductive pins 40 to move inwards.

[0045] Optionally, the elastic bridging component 31 is an elastic soft rubber structure. Common materials include silicone, thermoplastic elastomer (TPE), or thermoplastic polyurethane (TPU), which have good resilience. In this embodiment, the elastic soft rubber structure is designed to have an elastic force that pushes the first connecting unit 10 and the second connecting unit 20 away from each other. Specifically, the elastic soft rubber structure naturally exhibits a slightly open posture, or it has a tendency to spring back outwards. The beneficial effect of this design is that when the two connecting units are inserted into the host socket, the elastic force can provide a certain lateral support to prevent loosening; at the same time, when not inserted, the two units maintain a certain degree of separation, making it easy for medical personnel to grasp and operate them separately, avoiding difficulty in separating them due to excessive tightness.

[0046] In terms of structural connection, in order to ensure the connection between the elastic bridging member 31 and the first connecting unit 10 and the second connecting unit 20, the connecting assembly 30 also includes a connecting ring 32. The connecting ring 32 is fixed to both ends of the elastic bridging member 31, and the connecting ring 32 is sleeved and fixed to the outer periphery of the first connecting unit 10 and the second connecting unit 20.

[0047] In terms of shape design, the elastic soft rubber structure can be designed as a sheet-like structure that is narrow in the middle and wide at both ends. A sheet-like structure refers to its thinness, making it prone to bending deformation. The narrower middle region concentrates deformation stress in the central area, ensuring that the roots at both ends are less likely to break due to stress concentration. Furthermore, the ends of the elastic soft rubber structure are integrally molded with the connecting ring 32. This integral molding process is typically achieved using two-color injection molding or overmolding, eliminating physical seams and greatly improving the overall structural strength and sealing performance of the connecting assembly 30.

[0048] Optionally, the first connecting unit 10 and the second connecting unit 20 can be cylindrical or prismatic structures injection molded from rigid plastic, serving as insulating shells. The connecting ring 32 is tightly fitted onto the cylindrical or prismatic structure. The connection method can be interference fit or bonding. The presence of the connecting ring 32 effectively disperses the tensile stress generated when the elastic bridging component 31 deforms, preventing the elastic bridging component 31 from detaching from the first connecting unit 10 or the second connecting unit 20 to the greatest extent possible.

[0049] Furthermore, the outer periphery of the connecting ring 32 is provided with a first anti-slip texture 321. The first anti-slip texture 321 can be raised ribs or grooves distributed along the circumference of the connecting ring 32, or a knurled pattern. The first anti-slip texture 321 increases the coefficient of friction of the finger contact surface, providing a good anti-slip effect when medical personnel wear rubber gloves to operate, making it more stable and effortless to adjust the distance between the first connecting unit 10 and the second connecting unit 20.

[0050] In another embodiment, such as Figure 2and Figure 3 As shown, the electrosurgical unit connection device adapted to different host devices also includes a spacer housing 50. The first connecting unit 10 and the second connecting unit 20 are installed within the spacer housing 50. When the first connecting unit 10 and the second connecting unit 20 are installed in the spacer housing 50, they maintain a relatively fixed positional relationship due to the rigid constraint of the spacer housing 50. At this time, the distance between the two conductive pins 40 is locked at a standard value, such as 28.5 mm. This design allows medical personnel to install the connecting units into the housing and use it as a single plug when facing an industry-standard electrosurgical unit, providing a better insertion and removal feel, stronger stability, and protecting the internal elastic bridging component 31 from damage.

[0051] Optionally, the spacer housing 50 includes a first housing 51 and a second housing 52, which can be closed to enclose the first connecting unit 10 and the second connecting unit 20 within the spacer housing 50. The first housing 51 and the second housing 52 can be a structure in which the left and right halves meet, or a structure in which the upper and lower halves meet. Internally, there are receiving cavities that match the shape of the first connecting unit 10, the second connecting unit 20, and the elastic bridging member 31.

[0052] For easy and quick assembly and disassembly, the inner side of the first housing 51 is provided with a latching part 511, and the corresponding position of the second housing 52 is provided with a latching groove 521, allowing the latching part 511 to engage with the latching groove 521. Optionally, the latching part 511 can be an elastic cantilever with barbs, and the latching groove 521 is a recess with a locking platform. When the first housing 51 and the second housing 52 are closed and pressed together, the latching part 511 engages with the latching groove 521 to achieve locking, without the need for additional fasteners such as screws. When it is necessary to switch back to the "free adaptation mode", simply pry open or press the latch to separate the two housings and remove the internal connecting unit.

[0053] In addition, to facilitate insertion and removal, the outer periphery of the spacer housing 50 is provided with a second anti-slip texture 53. The second anti-slip texture 53 can be an anti-slip ridge provided on both sides of the housing, making it easier for the user to apply force for insertion and removal operations.

[0054] Through the design of the above embodiments, this application not only utilizes the elastic soft rubber structure to achieve compatibility with any non-standard hole spacing host, but also retains a high-quality connection experience with standard host through the detachable fixed-distance housing 50, taking into account both versatility and professionalism.

[0055] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
