[0019] Reference Figures 1 to 4 According to this utility model, an easily adjustable electrocautery device includes a handle 100, a clamp 200, and a control assembly. The front end of the handle 100 is provided with an adjusting ring 110, and the outer circumference of the adjusting ring 110 is evenly spaced with multiple teeth 120. One end of the clamp 200 is provided with two clamp heads 210, and the other end of the clamp 200 is rotatably disposed within the adjusting ring 110. The control assembly includes a trigger 130, a transmission rod 220, and a knob 300. The trigger 130 is movably disposed at the rear end of the handle 100. The transmission rod 220 is disposed inside the clamp bar 200. The trigger 130 is connected to the clamp head 210 via the transmission rod 220 to control the opening and closing of the two clamp heads 210. The knob 300 includes a rotating part 310 and a connecting part 320. The rotating part 310 is rotatably sleeved on the adjusting ring 110. The inner side of the rotating part 310 is provided with a protrusion 330. The protrusion 330 can be engaged between the two teeth 120 therein. The protrusion 330 and / or the teeth 120 are made of elastic material. The connecting part 320 is fixedly connected to the clamp bar 200.

[0020] It is understood that the easily adjustable electrocoagulation instrument provided in this embodiment of the invention provides a protrusion 330 on the inner side of the rotating part 310 of the knob 300, which engages with the teeth 120 on the outer periphery of the adjusting ring 110, so that the knob 300 generates a step-by-step damping sensation during rotation. This structure effectively prevents excessive rotation or loss of control due to uneven force application, helping doctors achieve precise fine-tuning and improving the stability and controllability of the operation. It is understood that the engagement action between the protrusion 330 and the teeth 120 provides a clear "segmentation" or "click" sensation, allowing doctors to perceive the adjustment steps without directly looking at the adjustment area, which is suitable for surgical scenarios with limited space or poor visibility, improving ease of use. Furthermore, the protrusion 330 and / or the teeth 120 are made of elastic materials (such as rubber or elastic plastic), which can achieve stable engagement and release without the need for additional springs or complex damping mechanisms, simplifying the overall structure, reducing production costs, and ensuring long-term durability. This utility model embodiment can improve the operating feel and adjustment accuracy, helping doctors to control the direction of the forceps head 210 more accurately and stably. It effectively solves the problems of inaccurate adjustment and poor feel of traditional electrocoagulation instruments. It has the advantages of reasonable structure, convenient operation and precise control, and is suitable for widespread application in the medical field.

[0021] Preferably, in some embodiments, the shape of the teeth 120 can be a semi-circular or arc-shaped groove with equal spacing, and the shape of the protrusions 330 can be a hemispherical or cylindrical round-headed protrusion 330. The advantage is that the contact surfaces of the two are point or small-face contact, which allows for smooth sliding, and the protrusions 330 have a noticeable "click" when entering the groove. In some embodiments, the shape of the teeth 120 can be a V-shaped groove with a sharp or rounded bottom, and the shape of the protrusions 330 can be a conical or triangular protrusion 330. The advantages are accurate positioning, strong resistance to lateral forces, easy alignment of the protrusions 330 with the groove, and good self-guiding properties. In some embodiments, the shape of the teeth 120 can be a rectangular tooth and groove alternating, and the protrusions... The shape of 330 can be square or trapezoidal, which has the advantages of high structural strength, strong torsional resistance, and the ability to transmit large torque. In some embodiments, the shape of the tooth 120 can be a continuous wavy undulating groove, and the shape of the protrusion 330 can be a round-headed protrusion 330 to slide along the undulating groove. The advantage is that it can achieve continuous variable damping (non-step type) and smooth feel. In some embodiments, the shape of the tooth 120 can be multiple arc-shaped pits evenly distributed (non-continuous teeth), and the shape of the protrusion 330 can be multiple small round protrusions distributed in a star shape. The advantage is that it is similar to a "ratchet + ball" structure, which can provide stable damping through multi-point cooperation, and the fineness can be controlled and adjusted by adjusting the number of protrusions.

[0022] Furthermore, refer to Figure 2 and Figure 3According to some embodiments of the present invention, the connecting part 320 is a shaft, the connecting part 320 is disposed inside the rotating part 310 and arranged coaxially with the rotating part 310, the connecting part 320 is rotatably inserted into the adjusting ring 110, and the clamp rod 200 is disposed in the connecting part 320 and fixedly connected to the connecting part 320.

[0023] Understandably, by designing the connecting part 320 as a shaft coaxial with the rotating part 310 and directly inserting it into the adjusting ring 110, a stable transmission connection between the knob 300 and the clamp bar 200 is achieved. The coaxial arrangement ensures concentricity during rotation, reduces eccentric wobbling, and improves adjustment smoothness; at the same time, the clamp bar 200 is built into and fixed in the connecting part 320, enhancing the rigidity of the overall structure and the reliability of the connection, avoiding adjustment failure or inaccurate operation due to loosening.

[0024] Preferably, according to some embodiments of the present invention, the connecting part 320 is provided with a fixing hole (not shown in the figure), and the clamp rod 200 is provided with a corresponding connecting hole (not shown in the figure). The fixing hole and the connecting hole are fixedly connected by a shaft pin, but it is not limited to this. Other fixed connection methods, such as buckles, bolts and other structural methods, can also be used according to actual needs, which will not be described in detail here.

[0025] Understandably, by providing fixing holes and connecting holes on the connecting part 320 and the clamp bar 200 respectively, and using a pin for connection, a secure assembly between the clamp bar 200 and the connecting part 320 is achieved. This connection method has a simple structure, is easy to assemble and disassemble, and has good shear and torsional resistance, effectively transmitting rotational torque, preventing relative slippage or detachment during use, and improving the durability and safety of the instrument.

[0026] Preferably, according to some embodiments of the present invention, the rotating part 310 is configured as a gear. It is understood that configuring the rotating part 310 as a gear-shaped structure not only facilitates finger gripping and force application, enhances friction, and prevents slippage, but also makes the overall appearance more functionally recognizable. The gear-shaped shape, in conjunction with the internal protrusion 330 structure, further enhances the tactile feedback and operational feedback during rotation, helping doctors achieve more precise angle adjustments during surgery and improving the human-computer interaction experience.

[0027] Specifically, refer to Figure 2 and Figure 3According to some embodiments of this utility model, the clamp bar 200 includes an insulating outer tube 230 and a conductive inner tube 240 disposed within the insulating outer tube 230, with a transmission rod 220 disposed within the conductive inner tube 240. It is understood that this structure achieves both current conduction and effectively prevents current leakage, ensuring surgical safety. The conductive inner tube 240 transmits high-frequency electrical energy to the clamp head 210, while the transmission rod 220 is used for mechanical transmission control of the opening and closing of the clamp head 210. Both are coaxially arranged within the insulating outer tube 230, resulting in a compact structure with high space utilization. Simultaneously, it avoids interference between electrical and mechanical components, improving the integration and reliability of the instrument.

[0028] Furthermore, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the control component further includes a first conductive element 140, a second conductive element 150, a first wire 160, and a second wire 170. The first conductive element 140 and the second conductive element 150 are electrically connected to the conductive inner tube 240 and the transmission rod 220, respectively. The conductive inner tube 240 and the transmission rod 220 are electrically connected to the two clamp heads 210, respectively. The first wire 160 and the second wire 170 are electrically connected to the first conductive element 140 and the second conductive element 150, respectively. The first wire 160 and the second wire 170 are used to electrically connect to an external power source.

[0029] Understandably, this electrical connection structure enables the stable transmission of high-frequency current from an external power source through wires, conductive components, the conductive inner tube 240, and the transmission rod 220 to the two clamp heads 210, forming a complete electrical circuit. The independent first and second conductive components 150 connect to different electrode paths, ensuring the normal operation of the bipolar electrocoagulation function and avoiding the risk of short circuits or leakage. The entire circuit layout is reasonable and well-insulated, improving the safety and stability of the electrocoagulation process, making it suitable for precision tissue processing.

[0030] It should be noted that, in this embodiment of the utility model, the specific installation method of the first conductive element 140 and the second conductive element 150, as well as the transmission connection method between the trigger 130 and the forceps head 210, can refer to the prior art (such as patent CN223095615U A bipolar electrocoagulation forceps and electrosurgical instrument), and will not be described in detail here.

[0031] Preferably, according to some embodiments of this utility model, the handle 100, trigger 130, and knob 300 are all made of insulating material, which improves safety during use and prevents electric shock accidents during surgery. At the same time, the insulating material has the advantages of being lightweight, heat-resistant, and easy to process, which helps to reduce the overall weight of the instrument, improve grip comfort, and is suitable for long-term surgical operations.

[0032] Preferably, according to some embodiments of this utility model, the outer surface of the handle 100 is provided with anti-slip texture, which enhances the friction when the doctor holds the instrument, prevents the instrument from slipping due to hand sweat or liquid contamination, and improves operational stability. Especially in critical stages such as delicate operations or emergency hemostasis, it can effectively prevent loss of instrument control and ensure surgical safety. In addition, the anti-slip texture can also improve grip comfort, reduce hand fatigue, and enhance the overall user experience.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
