Description

Technical Field

[0001] This invention relates to a surgical electrode, and more specifically, to a multi-interface plasma bipolar radio frequency conversion surgical electrode. Background Technology

[0002] The multi-interface plasma bipolar radiofrequency conversion surgical electrode is an energy device used in minimally invasive surgery. It uses radiofrequency energy to excite a thin plasma layer between the two electrode heads to achieve precise cutting, ablation and coagulation of target tissues. Existing plasma surgical electrodes have relatively limited connector types, typically equipped with only one specific interface specification, compatible only with corresponding brand of host equipment. The incompatibility of interface specifications between different brands and models of host equipment forces medical institutions to equip themselves with multiple sets of surgical electrodes for different host equipment. This not only significantly increases medical costs but also creates the dilemma of incompatible electrodes when the host equipment needs to be changed during surgery, affecting the continuity and efficiency of the procedure. Furthermore, the angle adjustment of the electrode head mainly relies on the operator rotating the entire handle, lacking an independent orientation adjustment mechanism. However, when multiple types of connectors and cables are concentrated at the rear end of the surgical electrode, the rear end of the handle becomes noticeably heavier, and the overall center of gravity shifts backward. If the traditional angle adjustment method of rotating the entire handle is continued, it will not only be laborious to operate, but will also pull on multiple cables, affecting the smoothness of operation, and may even lead to loosening of the interface or poor contact. In addition, during long-term surgery, the operator's hand is prone to sliding back and forth along the handle axis due to force or sweating. This not only leads to poor consistency in the control of the blade, but also increases the continuous tension of the hand muscles, accelerates fatigue, and, more seriously, the fingers may slide towards the blade shaft, posing a risk of contaminating the sterile area or accidentally touching the patient's tissue.

[0003] In view of this, we propose a multi-interface plasma bipolar radiofrequency conversion surgical electrode. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-interface plasma bipolar radiofrequency conversion surgical electrode to address the problems mentioned in the background art regarding how to solve the following issues without significantly increasing the size of the handle and the number of parts: controllability of independent angle adjustment, stable angle maintenance, reliable grip positioning, safety of placement in multiple scenarios, and quantitative visibility of angle adjustment in multi-interface integrated plasma bipolar radiofrequency surgical electrodes, given that the center of gravity of the handle shifts backward and the overall rotation angle adjustment method fails.

[0005] To achieve the above objectives, the present invention provides a multi-interface plasma bipolar radiofrequency conversion surgical electrode, including a handle housing, the front end of which is connected to a dual electrode head via a blade, and the rear end of which is connected to multiple different types of connectors via an assembly. The handle housing has a rotatably sealed inner core near the front end. The end of the inner core extends out of the handle housing and connects to the blade bar. The inner core also serves as a carrier for the electrical connection between the connector and the dual electrode head. An external orientation control is connected to the outer wall of the connecting inner core. This external orientation control is rotatably sleeved on the outer wall of the handle housing and is used to rotate the connecting inner core under external force, thereby changing the orientation angle of the tool holder and the dual electrode head. The outer wall of the handle housing is also provided with a strength limiting member, which elastically abuts against the outer wall of the orientation control and provides damping force for the rotation of the orientation control. The strength limiting component and the orientation control are combined to form a grip structure with front and rear limiting, as well as a support structure that fits various scenarios.

[0006] As a further improvement to this technical solution, the orientation external control includes at least a protrusion fixedly connected to the outer wall of the connecting inner core, and the end of the protrusion is provided with a ring-shaped rotating sleeve, wherein: The rotating sleeve is rotatably fitted onto the outer wall of the handle housing, and the side wall of the rotating sleeve is provided with an extension rod, the end of which is provided with a rear limiting spring.

[0007] As a further improvement to this technical solution, a positioning arc plate is provided on the inner side of the rear limiting spring, and the positioning arc plate and the extension rod are both fitted to the contour of the outer wall of the handle housing.

[0008] As a further improvement to this technical solution, an azimuth groove is provided on the outer wall of the handle housing near the end. The azimuth groove is adapted to slide with the protrusion, and the azimuth groove is a 1 / 4-3 / 4 arc-shaped groove.

[0009] As a further improvement to this technical solution, a scale is provided on the outer wall of the handle housing near the assembly, and the scale is used to display the rotation range of the orientation control.

[0010] As a further improvement to this technical solution, the strength limiting component includes at least a mounting plate fixed to the outer wall of the handle housing by bolts, and a front limiting spring is provided at the end of the mounting plate, the end of the front limiting spring abutting against the outer wall of the rotating sleeve, wherein: The end of the front limiting spring contact sleeve is an arc shape that is wider at the top and narrower at the bottom.

[0011] As a further improvement to this technical solution, both the front limiting spring and the rear limiting spring are made of inverted "V"-shaped metal material. The protruding end of the front limiting spring is located near the front end of the handle housing and obliquely abuts against the outer wall of the rotating sleeve towards the outside of the handle housing. The protruding end of the rear limiting spring is located near the rear end of the handle housing. The front limiting spring and the rear limiting spring form a front-to-back clamping limiting space.

[0012] As a further improvement to this technical solution, the multi-scenario-compatible support structure includes: Synchronous suspension support: The overall structure is supported synchronously through strength limiting components and orientation external controls; The unilateral inclined support is mainly supported by either a strength limiting component or an external orientation control.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this multi-interface plasma bipolar radiofrequency conversion surgical electrode, when it is necessary to change the orientation angle of the dual electrode heads but the wrist is inconvenient to rotate, the operator can use the other hand to directly move the orientation control exposed on the outer wall of the handle housing, so that it rotates along the outer wall of the handle housing. This rotation action is synchronously transmitted to the connecting core, which drives the connecting core to rotate inside the handle housing, thereby driving the blade and dual electrode heads to rotate synchronously, realizing the change of the orientation angle of the dual electrode heads without the operator having to change the hand grip posture. On the other hand, it allows the operator to accurately adjust the blade direction of the dual electrode heads without having to readjust the posture of the handle housing after changing the host or switching modes. During this process, the strength limiting component on the outer wall of the handle housing elastically abuts against the outer wall of the orientation control. Through friction or damping force, the connecting inner core cannot easily rotate freely. When the operator moves the orientation control, they need to overcome the elastic resistance of the strength limiting component, thereby generating a clear sense of resistance. This gives the angle adjustment controllable damping characteristics, preventing the orientation control from rotating unexpectedly under gravity or slight touch, thus improving the stability and accuracy of orientation control.

[0014] 2. In this multi-interface plasma bipolar radiofrequency conversion surgical electrode, the strength limiting member and the orientation external control are combined to form a front-to-back limiting grip structure. The strength limiting member forms a front-to-back clamping limiting space with the orientation external control from the front and back. When the operator's fingers are held in this limiting space, the orientation external control blocks the front and the strength limiting member blocks the back, thereby effectively preventing the grip position from shifting back and forth along the handle axis. This provides the operator with a clear and stable hand positioning reference, improving the comfort and stability of long-term surgery. On the other hand, the support structure is suitable for multiple scenarios, including: the overall structure is supported synchronously by strength limiting components and external orientation controls, forming a raised support for the dual electrode heads when not in operation, so that the front and rear ends of the handle shell are suspended in the air simultaneously, with unilateral tilt support. Only by using any combination of strength limiting components and external orientation controls for support, the dual electrode heads are placed at a specific tilt angle, with the front end suspended in the air, to avoid the electrode heads contaminating the table surface and to facilitate the operator's access.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 Please see Figures 1-7 As shown, this embodiment provides a multi-interface plasma bipolar radiofrequency conversion surgical electrode, including a handle housing 1. The front end of the handle housing 1 is connected to a dual electrode head 3 via a blade 2. The rear end of the handle housing 1 is connected to multiple different types of connectors 5 via an assembly 4. All connectors 5 are electrically connected to the dual electrode head 3, forming a "many-to-one" electrical path. During surgery, the operator selects the corresponding connector 5 to connect to the host according to the interface specifications of different brands of host devices. Electrical connection between the host device and the dual electrode head 3 can be achieved without replacing the entire set of surgical electrodes. The radiofrequency energy output by the host device is conducted to the dual electrode head 3 through the selected connector and the internal circuit of the assembly 4, forming a plasma thin layer between the dual electrode heads 3 to cut, ablate, or coagulate the target tissue. The handle housing 1 has a connecting core 11 that is rotatably sealed inside near the front end. The end of the connecting core 11 extends out of the handle housing 1 and connects to the knife bar 2. The connecting core 11 also serves as a carrier for the electrical connection between the connector 5 and the dual electrode head 3. An orientation control 12 is connected to the outer wall of the connecting inner core 11. The orientation control 12 is rotatably sleeved on the outer wall of the handle housing 1 and is used to drive the connecting inner core 11 to rotate under external force, thereby changing the orientation angle of the tool holder 2 and the dual electrode head 3. The outer wall of the handle housing 1 is also provided with a strength limiting member 13, which elastically abuts against the outer wall of the orientation control 12 to provide damping force for the rotation of the orientation control 12; In summary, due to the concentrated arrangement of multiple connectors 5 and their connecting cables, the rear section of the handle housing 1 is significantly heavier, shifting the overall center of gravity rearward. While a single-interface electrode could have its dual-electrode head 3 angle adjusted by rotating the entire handle, the multi-interface electrode, with its numerous rear cables and connectors, experiences cable pull during rotation, affecting operational smoothness and potentially leading to loosening or poor contact. Furthermore, during surgery, the operator may need to change the adapter host interface, connector, or adjust the plasma energy mode due to changes in the surgical situation. This typically requires a temporary interruption of the operation for observation or repositioning. If a suitable electrode head angle needs to be found again after each energy mode switch, it increases surgical time. Therefore, if... Figure 1 and Figure 5 As shown, during operation, the operator holds or pinches the outer wall of the handle housing 1 with one hand to perform surgical operations. When it is necessary to change the orientation angle of the dual electrode head 3 but the wrist is inconvenient to rotate, the operator uses the other hand to directly move the orientation control 12 exposed on the outer wall of the handle housing 1, so that it rotates along the outer wall of the handle housing 1. This rotation action is synchronously transmitted to the connecting core 11, which drives the connecting core 11 to rotate inside the handle housing 1, thereby driving the blade 2 and the dual electrode head 3 to rotate synchronously, realizing the change of the orientation angle of the dual electrode head 3 without the operator having to change the hand grip posture. On the other hand, it allows the operator to accurately adjust the blade direction of the dual electrode head 3 without having to readjust the posture of the handle housing 1 after changing the main unit or switching modes. During this process, the strength limiting member 13 set on the outer wall of the handle housing 1 elastically abuts against the outer wall of the orientation control 12. Through friction or damping force, the connecting inner core 11 cannot easily rotate freely. When the operator moves the orientation control 12, he / she needs to overcome the elastic resistance of the strength limiting member 13, thereby generating a clear sense of resistance. This makes the angle adjustment have controllable damping characteristics, preventing the orientation control 12 from rotating accidentally under gravity or slight touch, and improving the stability and accuracy of orientation control. The strength limiting component 13 and the orientation external control 12 are combined to form a grip structure with front and rear limiting, as well as a support structure that fits multiple scenarios; In summary, since the existing plasma surgical electrode handles are mostly smooth cylindrical structures and lack an effective grip and positioning structure, when the operator holds them for a long time during the operation, the hand is prone to slipping back and forth along the handle axis due to force or sweating. This not only affects the stability of the blade control, but also increases hand fatigue. There is even a risk that the fingers will slip into the blade area, causing contamination or accidental contact. In addition, there is no special placement and support structure. Whether placed upright or on the side, the dual electrode head 3 at the front end of the blade can easily touch the operating table or drape, causing damage to the sterile barrier and increasing the risk of infection. Therefore, the strength limiting member 13 is combined with the orientation control 12: On the one hand, such as Figure 5 As shown, the grip structure with front and rear limiting is as follows: the strength limiting member 13 forms a front and rear clamping limiting space for the external positioning control 12 from the front and rear directions. When the operator's fingers are gripped in this limiting space, the external positioning control 12 blocks the front and the strength limiting member 13 blocks the rear, thereby effectively preventing the grip position from moving back and forth along the handle axis, providing the operator with a clear and stable hand positioning reference, and improving the operation comfort and stability of long-term surgery; On the other hand, support structures tailored to various scenarios include: Figure 7 As shown, the strength limiting member 13 and the orientation control 12 simultaneously support the overall structure, forming a support for raising the dual electrode head 3 in the non-operating state, so that the front and rear ends of the handle housing 1 are simultaneously suspended in the air, and as shown... Figure 6 As shown, the single-sided inclined support is supported by only one of the combination components 4, namely the strength limiting component 13 and the orientation external control 12. When the dual electrode head 3 is placed, it is at a specific tilt angle, with the front end suspended in the air, which avoids the electrode head from contaminating the table surface and makes it easy for the operator to pick it up.

[0019] 2. The multi-interface plasma bipolar radiofrequency conversion surgical electrode according to claim 1, characterized in that: based on the above, the specific structure is further disclosed in detail: To achieve synchronous rotation between the inner core 11 and the orientation outer control 12, the specific structure of the orientation outer control 12 needs to be further disclosed, such as... Figure 2 As shown, the orientation external control 12 includes at least a protrusion 122 fixedly connected to the outer wall of the connecting inner core 11. The end of the protrusion 122 is provided with a ring-shaped rotating sleeve 121, enabling a rotatable fit between the orientation external control 12 and the handle housing 1. Wherein: The rotating sleeve 121 is rotatably mounted on the outer wall of the handle housing 1, and the side wall of the rotating sleeve 121 is provided with an extension rod 123. The end of the extension rod 123 is provided with a rear limiting spring 124. When the operator moves the rear limiting spring 124 on the outside of the handle housing 1, the rear limiting spring 124 drives the rotating sleeve 121 to rotate along the outer wall of the handle housing 1 through the extension rod 123. The rotating sleeve 121 transmits the rotation action to the fixedly connected connecting core 11 through the protrusion 122. The connecting core 11 rotates synchronously, thereby driving the tool bar 2 and the dual electrode head 3 to change their orientation angle.

[0020] Specifically, a positioning arc plate 125 is provided on the inner side of the rear limit spring 124. The positioning arc plate 125 and the extension rod 123 are both fitted to the contour of the outer wall of the handle housing 1. When rotating, they slide along the outer wall of the handle housing 1, playing a radial positioning and guiding role, ensuring that the rotation process is smooth and does not wobble, which is beneficial to the smoothness and accuracy of angle adjustment.

[0021] Furthermore, an orientation groove 10 is provided on the outer wall of the handle housing 1 near the end. The orientation groove 10 is adapted to slide with the protrusion 122. The orientation groove 10 adopts a 1 / 4-3 / 4 arc-shaped groove. The protrusion 122 slides in the orientation groove 10. The mechanical blocking of the groove wall of the orientation groove 10 precisely limits and guides the rotation angle range of the connecting inner core 11, preventing excessive rotation or exceeding the design stroke. Structurally, it prevents excessive rotation, avoids the internal wire from getting tangled and broken, and ensures the safety of the operation.

[0022] It is worth noting that, such as Figure 3 As shown, a scale 14 is provided on the outer wall of the handle housing 1 near the assembly 4. The scale 14 is used to display the rotation range of the orientation control 12. The scale 14 is an angle mark or scale line set on the outer wall of the handle housing 1, such as 0°, 30°, 60°, 90°, etc. When the operator rotates the orientation control 12, the reference mark on the orientation control 12, such as the edge of the rear limit spring 124, the end of the rotating sleeve 121, or the end point of the positioning arc plate 125, is displaced relative to the fixed scale 14. By reading the corresponding position of the reference mark on the scale 14, the operator can quantitatively understand the rotation range and orientation angle of the current dual electrode head 3, realizing the visualization and quantifiable display of the rotation angle of the dual electrode head 3.

[0023] To ensure that the strength limiting component 13 can restrict the rotation of the orientation control 12 and generate a damping sensation during the rotation of the orientation control 12, the structure of the strength limiting component 13 needs to be further disclosed, such as... Figure 2 and Figure 4As shown, the strength limiting member 13 includes at least a mounting plate 132 fixed to the outer wall of the handle housing 1 by bolts. A front limiting spring 131 is provided at the end of the mounting plate 132. The end of the front limiting spring 131 abuts against the outer wall of the rotating sleeve 121. When the operator moves the directional control 12 to rotate the rotating sleeve 121, sliding friction occurs between the outer wall of the rotating sleeve 121 and the end of the front limiting spring 131. Because the front limiting spring 131 is elastic, its end is always pressed against the outer wall of the rotating sleeve 121 under the action of elastic force, continuously applying normal pressure during the rotation of the rotating sleeve 121, thereby generating a constant frictional torque. This frictional torque manifests as a damping sensation or resistance felt by the operator. The end of the front limiting spring 131 that contacts the rotating sleeve 121 is an arc shape that is wider at the top and narrower at the bottom, so that it forms an approximate line contact or narrow surface contact with the outer wall of the rotating sleeve 121, rather than a large area surface contact. The upper wide structure provides sufficient structural strength and resistance to deformation, while the lower narrow arc structure ensures that the contact surface is concentrated in a small area of ​​the outer wall of the rotating sleeve 121, making the friction force controllable, stable and predictable.

[0024] Both the front limiting spring 131 and the rear limiting spring 124 are made of inverted "V" shaped metal material. The protruding end of the front limiting spring 131 is located near the front end of the handle housing 1 and obliquely abuts against the outer wall of the rotating sleeve 121 towards the outside of the handle housing 1. The protruding end of the rear limiting spring 124 is located near the rear end of the handle housing 1. The inverted "V" shaped structure gives the spring excellent elastic deformation ability. When subjected to radial pressure, finger gripping force or radial component force of rotating sleeve rotation, the two arms of the "V" shape will elastically open or close, providing stable elastic reaction force. Furthermore, the finger can squeeze the front limiting spring 131 along the inclined surface, causing the end of the front limiting spring 131 to further squeeze the rotating sleeve 121, increasing the squeezing strength, which helps to ensure that the connecting inner core 11 does not rotate at all during surgery, and ensures the stability of the surgical angle.

[0025] In addition, a front-to-back clamping space is formed between the front limiting spring 131 and the rear limiting spring 124. The operator's fingers, usually the index and middle fingers, are naturally placed in this limiting space. The protruding end of the front limiting spring 131 acts as a front stop to prevent the fingers from sliding forward toward the blade 2, and the protruding end of the rear limiting spring 124 acts as a rear stop to prevent the fingers from sliding backward toward the assembly 4.

[0026] In summary, the overall working principle of this invention is as follows: During the procedure, the operator selects the corresponding connector 5 to connect to the host according to the interface specifications of different brands of host devices. The radio frequency energy output by the host device is conducted to the dual electrode head 3 via the selected connector → the internal circuit of the assembly 4 → the connecting core 11. The radio frequency energy excites the medium between the dual electrode heads 3 to form a plasma thin layer, which cuts, ablates or coagulates the target tissue. The operator holds the handle housing 1 with one hand, and the index and middle fingers naturally fall into the limiting space between the front limiting spring 131 and the rear limiting spring 124. The front limiting spring 131 has a protruding end as a front stop, and the rear limiting spring 124 has a protruding end as a rear stop. The fingers are stably clamped, and axial slippage can be prevented without force. The tighter the grip, the more the fingers squeeze the inclined surface of the front limiting spring → the spring further presses the rotating sleeve → the rotation damping increases instantly, and the angle stability is adaptively enhanced. When it is necessary to change the orientation of the dual electrode head 3 but the wrist is inconvenient to rotate, the operator can use the other hand to directly pry the rear limiting spring 124 exposed on the outer wall of the handle housing. The prying force passes through the extension rod 123 → rotating sleeve 121 → protrusion 122 → connecting inner core 11 → knife bar 2 → dual electrode head 3. The dual electrode head 3 can change its orientation angle arbitrarily within the range of 0°-180°. During the rotation, the front limiting spring 131 abuts against the outer wall of the rotating sleeve 121 to produce a uniform damping feeling. The operator can accurately control the rotation amplitude. The operator can glance at the scale 14 at the rear end of the handle housing 1 and read the scale value corresponding to the reference mark to know the precise rotation angle of the current dual electrode head 3. When temporarily placed and requiring elevation support, the electrode is placed flat on the table, with the bottom of the strength limiting member 13 and the orientation control 12 simultaneously contacting the table → the double support points suspend the front and rear ends of the handle in the air → the double electrode heads 3 are completely off the table, preventing contamination. When single-sided tilt support is required, the electrode is placed on its side, with only the bottom of the strength limiting member 13 or the orientation control 12 contacting the table → the combination with the assembly 4 forms a three-point support → the electrode is tilted with the blade tip facing upwards → facilitating quick access and keeping the blade tip away from contamination sources.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
