It is typically disposable, featuring corrosion-resistant and high-temperature-resistant electrode tips, and utilizes a flushing-aspiration tubing to ensure a clear surgical field and immediate removal of tissue debris. Existing flushing-aspiration ablation electrode devices typically incorporate adjustment mechanisms for adjusting the electrocoagulation component. These mechanisms include rotary and telescopic adjustments, but in current technology, these adjustments are integrated, resulting in unintuitive user operation and poor usability. Utility Model Content

[0003] The purpose of this invention is to solve the technical problems of existing ablation electrode devices having unintuitive adjustment operations and poor ease of use.

[0004] To achieve the objectives of this utility model, the following technical solution is adopted: A suction-ablation electrode device includes an electrocoagulation assembly and an adjustment assembly.

The rotating wheel is rotatably sleeved on the electrocoagulation assembly. The fixed base is spaced apart from the rotating wheel and coaxially arranged with the rotating wheel. The fixed base has a receiving cavity in which the electrocoagulation assembly passes. The first end of the sliding member is sleeved on the electrocoagulation assembly and slidably disposed on the fixed base, while the second end is slidably disposed on the main body. The elastic member is disposed in the receiving cavity and presses against the first end to allow the first end to move axially. The sliding member has an operating part located in front of the main body.

[0005] In some embodiments, the electrocoagulation assembly includes an outer tube and an inner tube passing through the outer tube, the outer tube being connected to the first end and the inner tube being connected to the rotating wheel.

[0006] In some embodiments, the outer tube, inner tube, rotating wheel, and fixed base are coaxially arranged, and the rotating wheel drives the inner tube to rotate 360° around the axial direction.

[0007] In some embodiments, the first end has a slot, and the outer tube end is engaged in the slot.

[0008] In some embodiments, the operating part is located above or below the fixed base, and the operating part is rod-shaped or ring-shaped.

[0009] In some embodiments, the first end is provided with an elastic arm, the elastic arm is provided with a protrusion, and the fixing seat is provided with a limiting groove, with the protrusion and the limiting groove corresponding to each other.

[0010] In some embodiments, a limiting plate is provided inside the receiving cavity, and limiting grooves are disposed on the limiting plate, with a plurality of limiting grooves arranged along the axial direction.

[0011] In some embodiments, the limiting groove is disposed on and penetrates the fixed base, the fixed base is provided with a pressing member, one end of the pressing member is connected to the fixed base, and the other end is provided with a pressing part corresponding to the limiting groove.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] <Example 1> like Figures 1 to 6As shown, this embodiment provides a suction ablation electrode device, including an electrocoagulation component 1 and an adjustment component 2. The electrocoagulation component 1 is used for electrocoagulation operation and is located at the front end of the main body 3. The adjustment component 2 is connected to the electrocoagulation component 1 and is used to control the extension, retraction, and rotation of the electrocoagulation component 1. The adjustment component 2 is connected to the main body 3 and is located between the electrocoagulation component 1 and the main body 3. The user controls the electrocoagulation component 1 by holding the main body 3 and operating the adjustment component 2 with their fingers. The adjustment component 2 includes a rotating wheel 21, a fixed base 22, a sliding member 23, and an elastic member 24. The rotating wheel 21 is rotatably mounted on the electrocoagulation component 1, meaning that the rotating wheel 21 can be rotated by the user. The fixed base 22 is spaced apart from the rotating wheel 21 and is coaxial with the rotating wheel 21. The rotating wheel 21 and the fixed base 22 are separate. The rotating wheel 21 rotates while the fixed base 22 remains stationary. The rotating wheel 21 is closer to the main body 3 than the fixed base 22, making it easier for the user to operate the rotating wheel after holding the main body. The rotating wheel controls the rotation of the electrocoagulation component 1 around the axis X. The fixed base 22 has a receiving cavity 221, in which the electrocoagulation assembly 1 passes. The first end 231 of the sliding member 23 is sleeved on the electrocoagulation assembly 1 and slidably disposed on the fixed base 22, that is, the first end 231 is connected to the electrocoagulation assembly 1 and can move relative to the fixed base 22 in the axial X direction. The second end 232 is slidably disposed on the main body 3, that is, the second end 232 can slide relative to the main body 3. By operating the sliding member 23, the user can make the sliding member 23 move linearly along the X-axis, thereby driving the electrocoagulation assembly 1 to extend and retract. The sliding member 23 and the rotating wheel 21 control the extension and rotation operations, respectively. In addition, the connection between the main body 3 and the fixed base 22 by the sliding member 23 makes the connection between the adjusting assembly 2 and the main body 3 more stable. Specifically, the fixed base 22 and the main body 3 are respectively provided with guide grooves 4 to limit the sliding of the first and second ends. The elastic element 24 is disposed within the receiving cavity 221 and presses against the first end 231 to allow the first end 231 to move axially. In this embodiment, the elastic element 24 is a spring. When the user operates the slider to move the first end 231 backward, the elastic element 24 is compressed, and the electrocoagulation assembly 1 retracts. When the user releases the slider, the elastic force of the elastic element 24 causes the slider 23 to reset, and the electrocoagulation assembly 1 extends. Through the above technical solution, the rotation and linear extension / retraction control of the electrocoagulation assembly 1 can be achieved by operating the rotating wheel 21 and the slider 23 respectively, simplifying the structure and making the operation logic clearer and less confusing. The slider 23 spans the rotating wheel 21 and its two ends are slidably disposed in the fixed seat 22 and the main body 3 respectively, which can improve the sliding stability and make the slider closer to the main body 3, facilitating operation. The slider 23 has an operating part 233, which is located in front of the main body 3. The operating part 233 can extend and retract along the X-axis, so that when the user holds the main body 3, he can directly contact the operating part 233 to perform push and pull operations. The extension and retraction control of the electrocoagulation component 1 can be completed without adjusting the hand grip posture, which improves the convenience and continuity of operation.Meanwhile, the size and shape of the operating part 233 can be ergonomically designed to better fit the fingers and reduce hand fatigue caused by prolonged operation.

[0029] Furthermore, the electrocoagulation assembly 1 includes an outer tube 11 and an inner tube 12 passing through the outer tube 11. The outer tube 11 is connected to the first end 231, so that the user can extend or retract the outer tube 11 in the X direction by operating the sliding member 23 to adjust the relative position of the outer tube 11 and the inner tube 12. The inner tube 12 is connected to the rotating wheel 21. Specifically, the inner tube 12 passes through the middle of the rotating wheel 21. When the rotating wheel 21 rotates, it can drive the inner tube 12 to rotate synchronously. Since the outer tube 11 is connected to the first end 231 of the sliding member 23, it remains relatively stationary when the sliding member 23 is not operated, thereby realizing the independent rotation of the inner tube 12 relative to the outer tube 11. The inner tube 12 can be used to deliver irrigation fluid or aspirate tissue debris. Its end is equipped with an electrocoagulation head 13. The rear end of the inner tube 12 can be connected to a power source to provide the current required for electrocoagulation. The outer tube 11, as the main structure of the electrocoagulation assembly, provides protection and support for the inner tube 12. Its connection with the sliding member 23 ensures axial extension and retraction under the action of the sliding member 23. The outer tube 11, inner tube 12, rotating wheel 21, and fixed base 22 are coaxially arranged, ensuring uniform force distribution during movement and reducing swaying or jamming caused by eccentricity. The rotating wheel 21 drives the inner tube 12 to rotate 360° around the axis. This omnidirectional rotation angle meets the operational needs of different surgical sites. Doctors can flexibly adjust the inner tube 12 according to the actual situation, completing multi-angle operations without moving the entire electrode device.

[0030] Furthermore, to ensure the stability of the connection between the outer tube 11 and the sliding member 23, the first end 231 has a slot 2311, in which the end of the outer tube 11 is engaged. The shape of the slot 2311 matches the contour of the end of the outer tube 11, achieving quick assembly and reliable fixation through a snap-fit ​​method. This prevents relative displacement between the outer tube 11 and the sliding member 23 during extension, retraction, or use, ensuring the stability of the electrocoagulation operation. The sliding member 23 has an operating part 233, located above or below the fixed base 22. The operating part 233 is rod-shaped or ring-shaped. When the operating part 233 is positioned below the fixed base 22, it avoids obstructing the view; when positioned above the fixed base, it prevents the sliding member 23 from sliding and squeezing the user's fingers holding the main body. In this embodiment, the operating part 233 is a rod-shaped structure extending radially along the fixed base 22 and located below the fixed base 22, facilitating thumb operation. When the user holds the main body 3, their thumb can naturally rest on the operating part 233, and by pushing or pulling the operating part 233, the slider 23 can be moved as a whole. The rod-shaped operating part 233 has a simple structure, occupies little space, and will not interfere with the operation of the rotary wheel 21. If a ring-shaped operating part is used, it can accommodate users with different finger operating habits, improving the comfort and flexibility of operation.

[0031] <Example 2> In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0032] like Figure 7 As shown, compared to Embodiment 1, the flushing and ablation electrode device provided in this embodiment has the following structural design differences: In this embodiment, the first end 231 is provided with an elastic arm 2312, and the elastic arm 2312 is provided with a protrusion 2313. The fixed seat 22 is provided with a limiting groove 222. The protrusion 2313 is correspondingly provided with the limiting groove 222. The elastic arm 2312 has a certain elastic deformation capability. When the sliding member 23 moves along the axial direction, the protrusion 2313 slides in the limiting groove 222. By cooperating with the limiting groove 222 at different positions, the stroke of the sliding member 23 can be segmented and limited, for example, positioning at different positions when the electrocoagulation component 1 extends or retracts. Specifically, the receiving cavity 221 is provided with a limiting plate 223, and a limiting groove 222 is provided on the limiting plate 223. Several limiting grooves 222 are arranged along the axial direction. The limiting plate 223 is integrally formed with the fixing seat 22 or connected by fasteners. The multiple limiting grooves 222 are arranged at intervals to provide multiple positioning positions for the protrusion 2313. The user can fix the electrocoagulation component 1 at different extension lengths according to the surgical requirements.

[0033] <Example 3> In this embodiment, the parts that are the same as in Embodiments 1 and 2 are given the same reference numerals, and the same text descriptions are omitted.

[0034] like Figure 8 and Figure 9 As shown, compared to Embodiment 1 and Embodiment 2, the flushing and ablation electrode device provided in this embodiment has the following structural design differences: In this embodiment, the limiting groove 222 is disposed on and penetrates the fixed base 22. The fixed base 22 is provided with a pressing member 224. One end of the pressing member 224 is connected to the fixed base 22, and the other end is provided with a pressing part 2241, which is correspondingly disposed with respect to the limiting groove 222. When it is necessary to adjust the position of the sliding member 23, the user presses the pressing part 2241, causing the pressing member 224 to undergo elastic deformation. The pressing part 2241 pushes the protrusion 2313 out of the limiting groove 222, releasing the positioning restriction. At this time, the sliding member 23 can be pushed to move. After releasing the pressing member 224, the protrusion 2313 is engaged in the adjacent limiting groove 222 under the action of the elastic arm 2312 to complete the positioning. The pressing member 224 is disposed above the fixed base 22, and the sliding member 23 is disposed below the fixed base 22. The pressing member 224 and the sliding member 23 are respectively located on the upper and lower sides of the fixed base 22, so they do not interfere with each other during operation, which conforms to the ergonomic design.

[0035] In the above embodiments one to three, during the working process, depending on the different working environments, some of the technical implementation methods of embodiments one to three can be combined or replaced.

[0036] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
