[0018] Furthermore, a middle portion of one end of the tweezer seat close to the conductive sheet protrudes upward to form a retaining rib, and the two loading holes are respectively located on both sides of the retaining rib.

[0019] Furthermore, the drip pipe also includes a hose portion connected to the steel pipe portion; an air avoidance hole is provided at one end of the shell, and the hose portion of the drip pipe passes through the air avoidance hole.

It is also easy to disassemble after assembly, which is convenient for later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0054] Example 1

[0055] like Figure 1-5 As shown, an embodiment of the present invention provides a bipolar electrocoagulation forceps, wherein the bipolar electrocoagulator can be a forceps type or a clamp type. The description and drawings of this embodiment are described using the forceps type structure as an example, but its improvements are also applicable to the clamp type. Secondly, it should be noted that the electrical part and working principle of the electrocoagulation forceps can refer to the existing structure, which is not described in this embodiment, and only the structural improvements made to the electrocoagulation forceps are described in detail.

[0056] Specifically, in the embodiment of the present invention, the bipolar electrocoagulation forceps include two relatively distributed forceps bodies 10 and a forceps seat 20, wherein each of the forceps bodies 10 includes a forceps tip 11 and a conductive sheet 12 that are relatively arranged, and the conductive sheets 12 of the two forceps bodies 10 are connected to the forceps seat 20 to enable the forceps tips 11 of the two forceps bodies 10 to be relatively close to or far away from each other; the forceps seat 20 includes: two mounting grooves 21, which are opened on the left and right sides of the forceps body 10 and are adapted to the conductive sheet 12 of the forceps body 10, and are used to install the conductive sheet 12; two pressure The wire grooves 22 are respectively opened on the two installation grooves 21, and are used to compress the conductive end 31 of the conductive wire 30; the two wire grooves 23 are respectively opened on the upper and lower sides of the tweezers body 10 and are connected with the wire pressing groove 22, and are used to quickly organize the conductive wire 30 inside the tweezers seat 20 to avoid confusion or interference of the conductive wire 30 in operation, thereby improving the overall neatness and ease of operation; by installing the conductive sheet 12 of the tweezers body 10 in the installation groove 21, the conductive end 31 of the conductive wire 30 placed in the wire pressing groove 22 can be compressed.

[0057] In the embodiment of the present invention, during installation, the conductive wire 30 is first placed in the wire groove 23 of the tweezers seat 20, and then the conductive end 31 of the conductive wire 30 is placed in the wire pressing groove 22, and it is ensured that it is completely located in the wire pressing groove 22, and then the conductive sheet 12 of the tweezers body 10 is installed in the installation groove 21 of the tweezers seat 20. At this time, the conductive end 31 is clamped between the conductive sheet 12 of the tweezers body 10 and the wire pressing groove 22, so that the tweezers body 10 and the conductive wire 30 can be quickly and firmly connected, avoiding the problems of material damage, operation complexity and loose welding in the traditional welding process, and simplifying the assembly process, making the assembly of the electrocoagulation tweezers easier, and also convenient for disassembly for cleaning or replacement of parts, effectively reducing production time and improving production efficiency.

[0058] Among them, in this embodiment, an interference fit is adopted between the conductive sheet 12 and the mounting groove 21, thereby enhancing the stability of the connection between the tweezers body 10 and the tweezers seat 20, and at the same time, the conductive end 31 of the conductive wire 30 located in the wire pressing groove 22 can be fully pressed, avoiding the risk of loose wires or poor contact, and ensuring the stable conduction of current. At the same time, the depth of the wire pressing groove 22 is set to be less than the thickness of the conductive end 31 of the conductive wire 30, causing the conductive end 31 to slightly protrude from the notch, so that the conductive sheet 12 of the tweezers body 10 can apply stronger pressure to the conductive end 31, achieve a closer contact, and prevent the conductive end 31 from sliding or displacing in the groove. Due to the shallow depth of the wire pressing groove 22, the conductive end 31 is subjected to a greater pressing force, thereby increasing the contact area between the conductive end 31 and the conductive sheet 12, and optimizing the contact and conductive effect between the conductive wire 30 and the tweezers conductive sheet 12. Specifically, the depth of the wire pressing groove 22 is about 2 / 3 of the thickness of the conductive end 31 of the conductive wire 30 (the pre-pressed part is about 1 / 3).

[0059] In addition, the wire groove 23 is set in an L-shaped structure, and the corners of its inner wall are rounded. This structure effectively limits the moving direction of the conductive wire 30, ensuring that the conductive wire 30 is stably arranged in the wire groove 23 to prevent sliding or falling off. The rounded corner setting makes the conductive wire 30 smoother when passing through the slot, avoiding jamming or scratching, and significantly improving the efficiency of the installation process.

[0060] Specifically, Figure 3-5 As shown, in the embodiment of the present invention, a plurality of mounting holes 24 are provided on the tweezers seat 20, and the mounting holes 24 pass through the two mounting grooves 21; a plurality of positioning holes 121 used in conjunction with the mounting holes 24 are respectively provided on the conductive sheets 12 of the two tweezers bodies 10, and the mounting holes 24 and the positioning holes 121 are used for fasteners 40 to pass through, so as to install the conductive sheets 12 of the two tweezers bodies 10 on the tweezers seat 20, and the conductive sheets 12 of the tweezers bodies 10 are tightly fixed on the tweezers seat 20 by the fasteners 40, thereby ensuring that the connection between the tweezers body 10 and the tweezers seat 20 is very stable.

[0061] Moreover, this connection method not only enhances the stability of the forceps body 10, but also further improves the compression effect of the conductive end 31 of the conductive wire 30 in the wire pressing groove 22. Since the conductive end 31 is fully compressed, the displacement or loosening of the conductive wire 30 during use is avoided, thereby effectively reducing the risk of poor contact and ensuring that the electrocoagulation forceps can stably and efficiently conduct current during operation.

[0062] Secondly, by passing the fastener 40 through the positioning hole 121 and the mounting hole 24, the conductive sheet 12 of the tweezer body 10 is accurately fixed on the tweezer seat 20, avoiding the misalignment or inaccurate position of the tweezer body 10 due to external forces during operation or use, thereby ensuring the stability and accuracy of the device. In addition, the precise matching of the positioning hole 121 and the mounting hole 24 also makes the assembly process of the tweezer body 10 and the tweezer seat 20 easier and faster, which not only improves production efficiency, but also reduces possible errors during the assembly process, further enhancing the quality and reliability of the overall product.

[0063] Among them, in this embodiment, the fastener 40 is a positioning pin, and the positioning pin passes through the mounting hole 24 of the tweezers seat 20 and is interference fit with the positioning hole 121 of the conductive end 31. The positioning pin is tightly combined with the positioning hole 121 of the conductive end 31 through interference fit, ensuring that the connection between the conductive sheet 12 of the tweezers body 10 and the tweezers seat 20 is very firm and not easy to loosen, and effectively improves the stability of the connection, avoiding the risk of loosening or misalignment of the connection between the tweezers body 10 and the tweezers seat 20 due to operation or external force.

[0064] Based on the above scheme, if Figure 2As shown, in the embodiment of the present invention, a positioning groove 70 is provided on one of the two forceps bodies 10, and a positioning protrusion 60 that can be plugged into and cooperate with the positioning groove 70 is provided on the other of the two forceps bodies 10. When the two forceps bodies 10 are relatively closed, the positioning protrusion 60 is inserted into the positioning groove 70, thereby realizing precise positioning of the forceps bodies 10 and effectively preventing the two forceps bodies 10 from being offset or misaligned during use, thereby ensuring the stability and accuracy of the electrocoagulation forceps.

[0065] In addition, the cooperation between the positioning protrusion 60 and the positioning groove 70 can also limit the distance between the two tweezers bodies 10 when they are closed. Specifically, during operation, the positioning protrusion 60 moves toward the positioning groove 70 until the positioning protrusion 60 completely enters the positioning groove 70 and contacts the bottom of the groove. At this time, the tweezer tips 11 of the two tweezers bodies 10 are close to each other, but they will not contact or squeeze due to excessive pressure. This can effectively avoid damage to the tweezers body 10 or the tweezer tips 11 due to excessive pressure, and provides a certain degree of protection.

[0066] Secondly, the inner contour of the positioning groove 70 is an ellipse, and the outer contour of the corresponding positioning protrusion 60 is also an ellipse. The ellipse setting enables the two parts to adjust themselves within a certain range, ensuring that the cooperation between the positioning protrusion 60 and the groove is more stable.

[0067] In addition, the matching surfaces of the positioning groove 70 and the positioning protrusion 60 are inclined, which makes the plugging process smoother. The inclined surface provides a certain guiding effect, helping the positioning protrusion 60 to easily insert into the positioning groove 70, reducing friction and resistance during plugging, thereby making the assembly process simpler and faster, improving installation efficiency, and avoiding problems caused by poor docking.

[0068] Based on the above scheme, if Figure 3 As shown, in an embodiment of the present invention, an air-avoiding groove 13 for pre-burying a dripping pipe 80 is provided on opposite sides of the two forceps bodies 10. By installing the dripping pipe 80 in the air-avoiding groove 13, the bipolar electrocoagulation forceps can not only perform electrocoagulation and hemostasis operations, but also provide a flushing function, thereby achieving more efficient operation. During the electrocoagulation process, the dripping pipe 80 can release water flow to help dissipate heat and reduce the heat generated during electrocoagulation, thereby preventing tissue damage caused by overheating. At the same time, the water flow can prevent the electrocoagulated tissue from adhering to the forceps tip 11, thereby reducing the situation where the normal operation of the bipolar electrocoagulation forceps is affected by tissue adhesion.

[0069] In addition, the left and right sides of the forceps seat 20 are respectively provided with a void cavity 25 connected to the installation groove 21, and the void cavity 25 and the void groove 13 together form a channel, which provides a convenient space for the installation and arrangement of the dripping pipe 80. Through this arrangement, not only is it convenient to arrange the dripping pipe 80 reasonably, but it also ensures that the dripping pipe 80 can maintain a stable fixed position during use, avoiding displacement or loose connection of the dripping pipe 80 due to external force or improper operation.

[0070] Based on the above scheme, if Figure 1-2 As shown, in an embodiment of the present invention, the bipolar coagulation forceps also include a shell 50, and the shell 50 is mounted on the forceps base 20 and the two conductive sheets 12. The provision of the shell 50 enhances the insulation and safety of the overall coagulation forceps, ensuring that during the electrocoagulation operation, the user will not directly contact the current conductive end 31, thereby preventing electric shock injuries due to misoperation or accidental contact, thereby improving the safety of the bipolar coagulation forceps.

[0071] Based on the above scheme, if Figure 1-2 As shown, in order to improve the operator's control accuracy of the bipolar electrocoagulation forceps during use and avoid the forceps body 10 slipping due to hand sweat, liquid contact or long-term use, thereby affecting the stability and safety of the operation, the present invention provides anti-slip grooves 14 on the opposite sides of the two forceps bodies 10. The anti-slip grooves 14 significantly improve the gripping stability of the forceps bodies 10, help the operator to more accurately control the opening and closing of the forceps bodies 10 and the operating force applied, thereby improving the accuracy and safety of the operation.

[0072] Specifically, the anti-slip pattern 14 adopts a wavy structure. The wavy setting can effectively increase friction, provide a firmer grip, and produce a larger contact area with the operator's finger surface, so that even after long-term use or when the hands become slippery due to sweat or other reasons, it can still maintain a high anti-slip effect. The curved structure of the wavy texture helps to increase friction with the hand skin and prevent the forceps body 10 from sliding during use, thereby ensuring that the operator can accurately and stably control the forceps body 10 when performing electrocoagulation operations.

[0073] In addition, the wavy anti-slip pattern 14 can not only enhance the safety during use and the stability of operation, but also reduce the fatigue caused by long-term operation to a certain extent. By enhancing the stability of the grip, the operator can more easily control the bipolar electrocoagulation forceps and reduce the discomfort caused by insufficient grip or slipping.

[0074] Specifically, in the embodiment of the present invention, the material of the tweezers holder 20 is PEEK (polyetheretherketone). PEEK material has excellent high temperature resistance and can work stably at higher temperatures. Its melting point is as high as 343°C, and it can withstand the high temperature that may be generated during the electrocoagulation operation without deformation or performance degradation. This allows the tweezers holder 20 to be used for a long time in a high temperature environment, maintain the stability of its structure, and avoid affecting the precise operation of the electrocoagulation tweezers due to thermal deformation.

[0075] Secondly, PEEK has excellent electrical insulation properties, which can effectively isolate the current and prevent the current from leaking or contacting the forceps holder 20 during use, thereby ensuring the safety of the operator. In particular, in bipolar electrocoagulation forceps, the current needs to be conducted at the forceps tip 11 of the forceps body 10, and the forceps holder 20 must have good electrical insulation to avoid short circuits or other electric shock risks caused by the conductive end 31 contacting the forceps holder 20.

[0076] Thirdly, PEEK material has strong corrosion resistance to a variety of chemical substances and can resist common corrosive substances, such as medical disinfectants, blood, body fluids, etc. This enables the tweezers holder 20 to maintain good performance during long-term use and avoid equipment failure or safety hazards caused by corrosion.

[0077] In addition, PEEK has high mechanical strength and can withstand large loads and external forces without breaking or deforming. During the use of bipolar electrocoagulation forceps, the forceps holder 20 not only needs to withstand the operating force of the forceps body 10, but also needs to withstand the high voltage and vibration during the electrocoagulation process. The high strength of PEEK ensures that the forceps holder 20 is not easily damaged under these conditions, thereby extending the service life of the device.

[0078] Based on the above scheme, if Figure 4-5 As shown, the bipolar electrocoagulation forceps of the embodiment of the present invention are also improved in the structure and packaging method of the forceps holder 20 to further improve the insulation, sealing, stability and structural firmness of the device.

[0079] Specifically, in this embodiment of the invention, the left and right sides of the tweezers seat 20 are respectively provided with air-avoiding cavities 25 connected to the mounting groove 21, and these air-avoiding cavities 25 together with the air-avoiding groove 13 previously arranged form an installation channel. The installation channel effectively optimizes the layout space of the drip pipe 80 or other electrical components, so that they can be more firmly fixed on the tweezers seat 20, while avoiding the change or loosening of the position of the components due to external forces during use, ensuring that the drip pipe 80 and other components can be smoothly arranged and will not become unstable or loose due to long-term use, thereby increasing the long-term reliability of the equipment.

[0080] Secondly, glue injection holes 26 are also provided on the tweezers seat 20, and these glue injection holes 26 run through the entire tweezers seat 20. During use, the tweezers seat 20, the tweezers tip 11 of the tweezers body 10, and the outer shell 50 can be packaged by injecting glue into the glue injection holes 26. This packaging process can not only further improve the insulation between the tweezers body 10 and the tweezers seat 20 and reduce the risk of current leakage, but also enhance the overall sealing, effectively prevent liquid or impurities from entering the tweezers seat 20, and ensure the reliability and stability of the equipment during the electrocoagulation operation. At the same time, the filling effect of the glue improves the structural stability, reduces the friction between components, and avoids loosening or damage of components during long-term use.

[0081] Furthermore, a positioning column 29 is provided on the inner side of the outer shell 50, and the positioning column 29 is plugged into the glue injection hole 26. The positioning column 29 plays a guiding and fixing role in the glue injection process, ensuring that the glue can evenly flow into the glue injection hole 26 and fill all the parts that need to be packaged. The presence of the positioning column 29 effectively avoids the problem of uneven filling that may occur during the inflow of glue, and ensures the consistency and stability of the packaging effect. The positioning column 29 enables a firm connection to be formed between the outer shell 50 and the tweezers seat 20, further improving the structural stability of the device, making the joint between the outer shell 50 and the tweezers seat 20 tighter, and preventing the outer shell 50 from loosening or being misplaced.

[0082] In addition, a guide bevel is provided at the end of the conductive sheet 12, which enables the conductive sheet 12 to dock with the tweezers seat 20 more smoothly when the conductive sheet 12 is installed on the tweezers seat 20, avoiding misalignment or jamming during the installation process, improving the smoothness of the assembly process, saving operation time and reducing the possibility of human error.

[0083] Example 2

[0084] like Figure 6-13As shown, the bipolar electrocoagulation forceps provided in the embodiment of the present invention are different from the above-mentioned embodiment 1 in that, in the embodiment of the present invention, the forceps seat 20 is provided with two loading holes 27, and the loading holes 27 run through the front and rear sides of the forceps seat 20; the drip tube 80 includes a steel pipe part 81, one end of the steel pipe part 81 is clamped in the air avoidance groove 13, and the other end is penetrated by the loading hole 27. By passing the steel pipe part 81 of the drip tube 80 through the loading hole 27, the drip tube 80 is physically isolated from the conductive sheet 12 of the forceps body 10, thereby preventing the current from leaking through the connecting part of the drip tube 80 or affecting the normal operation of the electrode, thereby ensuring electrical safety and improving the stability of the entire device. In addition, by physically connecting the steel pipe part 81 of the drip tube 80 with the air avoidance groove 13 of the forceps body 10 and the loading hole 27 of the forceps seat 20, the cumbersome glue filling process is eliminated, the production process is greatly simplified, the production process is made more efficient, and the problems that may be caused by uneven glue filling or incomplete curing are reduced. In addition, omitting the glue pouring process also directly reduces the production cost. Since it does not rely on the complicated glue pouring process but adopts a simple physical connection method, it is easier to achieve mass automated production, which significantly improves the production efficiency and has lower requirements for the production line. At the same time, after the equipment is assembled, due to the use of a plug-in setting, the installation and removal of the drip pipe 80 is very convenient, which is convenient for later maintenance and replacement, and reduces maintenance costs.

[0085] Based on the above scheme, if Figure 8-9 As shown, in the embodiment of the present invention, the middle part of one end of the tweezers seat 20 close to the conductive sheet 12 protrudes upward to form a retaining rib 28, and the two loading holes 27 are respectively located on both sides of the retaining rib 28. By arranging the retaining rib 28 at this position, not only the mechanical strength of the tweezers seat 20 is improved, but also it is ensured that the tweezers seat 20 is not easily deformed or damaged during long-term use, thereby increasing its durability and stability.

[0086] Secondly, the retaining ribs 28 also play a role of physical isolation. Specifically, the retaining ribs 28 further effectively block the arrangement of the two dripping pipes 80, so that the relative position between the dripping pipes 80 remains stable, avoiding interference or friction between the dripping pipes 80, ensuring that the dripping pipes 80 will not be offset or incorrectly positioned during operation, thereby ensuring the function and stability of the dripping pipes 80.

[0087] In addition, the distance between the loading holes 27 of the two dripping pipes 80 is L2, and the setting requirement of the distance satisfies L2 ≥ 2.5 mm. This setting ensures that there is enough space between the two dripping pipes 80, and avoids the dripping pipes 80 from contacting or squeezing each other due to being too close. By maintaining a reasonable distance, not only the arrangement of the dripping pipes 80 is more orderly, but also the damage caused by the dripping pipes 80 being too close during the working process can be avoided.

[0088] Based on the above scheme, if Figure 9-10 and Figure 12-13 As shown, in the embodiment of the present invention, the dripping pipe 80 also includes a hose portion 82 connected to the steel pipe portion 81; an air avoidance hole 51 is provided at one end of the shell 50, and the hose portion 82 of the dripping pipe 80 passes through the air avoidance hole 51. The air avoidance hole 51 can not only provide effective cooperation between the shell 50 and the electrode holder, so that the shell 50 plays a protective role on the electrode holder, but also guide and fix the hose portion 82 of the dripping pipe 80. After the hose passes through the air avoidance hole 51, it is stably positioned between the shell 50 and the electrode holder, thereby avoiding the hose from being misplaced or loosened due to force or movement during use, ensuring the stability of the dripping pipe 80 during operation, and at the same time, the hose portion 82 extends out through the air avoidance hole 51, which is convenient for connecting it to the supply system of the coolant or drug solution, which can not only ensure the smooth transmission of the fluid, but also facilitate the operator to connect and disconnect operations, thereby improving the convenience of use.

[0089] Secondly, the air-avoiding holes 51 on the shell 50 can also allow the conductive wire 30 to pass through the shell 50 smoothly, providing convenience for operation and maintenance, and these air-avoiding holes 51 are reasonably arranged on the shell 50, which not only ensures that the drip pipe 80 and the conductive wire 30 can be stably fixed during use, but also keeps the shell 50 compact as a whole without affecting the normal operation of the drip pipe 80. Among them, the air-avoiding holes 51 are in an "8"-shaped structure, and the two ends of the "8"-shaped structure can be used for the passage of the drip pipe 80 and the conductive wire 30 respectively, and can effectively fix the positions of these components to prevent these components from moving or loosening due to external forces during use, thereby ensuring the stability and reliability of the equipment during use. Compared with the traditional single hole setting, the "8"-shaped structure provides more wiring space, so that the drip pipe 80 or the conductive wire 30 can be arranged in a more flexible manner without affecting the stability and appearance of the shell 50.

[0090] Among them, in the embodiment of the present invention, the steel pipe part 81 and the hose part 82 are plug-fitted, the end of the steel pipe is inserted into the inner cavity of the hose, and is connected by interference fit, ensuring a strong connection between the steel pipe and the hose, thereby effectively preventing loosening or liquid leakage at the connection during use, and improving sealing and stability. At the same time, the plug-fit setting makes the installation and disassembly process simpler, the operation more efficient, and reduces the difficulty of maintenance.

[0091] Secondly, an assembly gap is left between the loading hole 27 and the steel pipe portion 81 of the dripping pipe 80, which effectively reduces the resistance during assembly and enables the dripping pipe 80 to be easily inserted into the loading hole 27, thereby improving production efficiency and simplifying the assembly process. Specifically, the assembly gap is L1, and the value range is 0.1 mm to 0.5 mm.
