Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a plasma surgical electrode and operating handle. Background Technology

[0002] Plasma surgical electrodes are widely used in clinical surgery for functions such as tissue cutting, ablation, and hemostasis. A plasma surgical electrode consists of a compatible cutting head and an operating handle. To save on usage costs, some technologies currently design the cutting head and operating handle of the plasma surgical electrode to be detachable. After a single or limited number of uses, the cutting head is discarded, while the operating handle is sterilized and reused. However, the operating handles in current technologies have poor water resistance, and the sterilization process can easily corrode the internal electrical components of the operating handle, affecting its lifespan. Utility Model Content

[0003] Therefore, it is necessary to provide a plasma surgical electrode and operating handle to address the technical problem of poor waterproofing of the operating handle.

[0004] The technical solution is as follows:

[0005] On one hand, an operating handle is provided, including a handle body, a sealing plug, and an operating button. The handle body has a mounting cavity with at least one open end. The mounting cavity is used for detachable connection with the electrode rod of a plasma surgical electrode. The sealing plug is detachably sealed to the opening. The sealing plug is used to seal the opening when the handle body and the blade structure are in a detached state. The operating button has at least one sealing engagement point with the handle body.

[0006] The technical solution will be further explained below:

[0007] In one embodiment, the handle body is provided with a button groove communicating with the mounting cavity, and the operation button is movably disposed in the button groove; along the axial direction of the button groove, there is at least one sealing engagement point between the operation button and the handle body.

[0008] In one embodiment, the operation button includes a cover and a button post connected to each other. The button post is movably inserted through the button slot and can partially extend into the mounting cavity. The cover is disposed outside the button slot and is sealed and fitted to the outer side wall of the handle body.

[0009] In one embodiment, the cover is further provided with a mounting sleeve that surrounds the button post and is spaced apart from the button post, the mounting sleeve being at least partially sealed to the inner sidewall of the button slot.

[0010] In one embodiment, the mounting sleeve is provided with a first sealing part, and the handle body is provided with a second sealing part, wherein the first sealing part and the second sealing part are sealed together.

[0011] In one embodiment, one of the first sealing part and the second sealing part is a sealing groove, and the other is a sealing protrusion. The sealing protrusion is inserted into and sealed to fit the sealing groove.

[0012] In one embodiment, the mounting sleeve further includes a bent portion disposed within the mounting cavity, the bent portion being sealed and fitted against the inner wall of the mounting cavity.

[0013] In one embodiment, the operating handle further includes a button control board, a wire, and a sealing sleeve. The button control board is disposed in the mounting cavity. One end of the wire is electrically connected to the button control board, and the other end of the wire extends to the outside of the mounting cavity. The sealing sleeve is fitted around the outer periphery of the wire and seals against the inner wall of the mounting cavity.

[0014] In one embodiment, the button control panel is provided with a display section, the handle body is provided with a display window corresponding to the display section, and the operating handle further includes a transparent shielding member disposed in the display window, the transparent shielding member being sealed to the inner wall of the display window.

[0015] On the other hand, a plasma surgical electrode is provided, including a blade, an electrode rod, and the aforementioned operating handle. The blade is disposed at one end of the electrode rod, and the other end of the electrode rod is inserted into and adapted to the mounting cavity.

[0016] The plasma surgical electrode and operating handle of the above embodiments achieve a seal by sealing the opening with a plug when the electrode rod of the plasma surgical electrode and the handle body are in a detached state. During the sterilization process of the handle body, this effectively prevents external disinfectants and other foreign matter from seeping into the mounting cavity through the opening and damaging the electrical components inside, thus ensuring service life. Furthermore, because there is at least one sealed mating point between the operating button and the handle body, it effectively prevents external blood, water, and other foreign matter from seeping into the mounting cavity and damaging the electrical components during surgery or sterilization, thus ensuring service life.

[0027] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] like Figure 1As shown, in one embodiment, a plasma surgical electrode is provided, including a blade (not shown), an electrode rod (not shown), and an operating handle 10. The blade is disposed at one end of the electrode rod, and the other end of the electrode rod is compatible with the operating handle 10, thereby providing operational support, energy output, and control functions for the electrode rod. This allows the blade to be used for functions such as cutting, ablation, and hemostasis of tissue.

[0029] Optionally, the electrode rod and the operating handle 10 are assembled and connected by a detachable method such as snap-fit ​​or plug-in, so that the electrode rod can be discarded and replaced separately after one or more uses, reducing the cost of use.

[0030] It should be noted that the electrode rod and the cutting head can adopt existing structures, which will not be described in detail here.

[0031] like Figures 1 to 3 As shown, in one embodiment, an operating handle 10 is provided, including a handle body 100, a sealing plug 700, and operating buttons 200.

[0032] The handle body 100 may be shell-shaped for easy gripping. The handle body 100 has a mounting cavity 110 with at least one opening 111. The mounting cavity 110 is used for detachable connection with the electrode rod via a plug-in engagement or other method. The sealing plug 700 is detachably sealed to the opening 111. The sealing plug 700 is used to seal the opening 111 when the handle body 100 and the electrode rod are detached. Furthermore, the operation button 200 has at least one sealing engagement point with the handle body 100.

[0033] Among them, the sealing plug 700 can be made of rubber plugs or other structures.

[0034] In one embodiment, the sealing plug 700 includes a cap end and a sealing end. The sealing end is inserted into the opening 111 and enters the mounting cavity 110 to seal, while the cap end is located outside the opening 111 and seals against the end of the handle body 100, improving the sealing effect. Furthermore, the sealing end may also have a clearance cavity to avoid electrical components (such as pins for electrical connections) inside the mounting cavity 110. Additionally, the sealing end can be assembled with the opening 111 using an interference fit or other methods to ensure reliable sealing.

[0035] In the above embodiment, the operating handle 10, when the electrode rod and handle body 100 are detached, achieves a seal by sealing the opening 111 with the sealing plug 700. During the sterilization process of the handle body 100, this effectively prevents external disinfectant or other foreign matter from seeping into the mounting cavity 110 through the opening 111 and damaging the electrical components inside, thus ensuring its service life. Furthermore, because the operating button 200 and the handle body 100 have at least one sealed mating point, during the surgical or sterilization process, it effectively prevents external blood, water, or other foreign matter from seeping into the mounting cavity 110 and damaging the electrical components, thus ensuring its service life.

[0036] In one embodiment, the handle body 100 is provided with a button groove 120 communicating with the mounting cavity 110. Optionally, the mounting cavity 110 extends along the axial direction of the handle body 100, and the button groove 120 extends along the thickness direction of the handle body 100. The operation button 200 may be in the shape of a button or similar structure, facilitating finger pressing. Part of the operation button 200 is movably disposed within the button groove 120. Furthermore, along the axial direction of the button groove 120 (e.g., ... Figure 3 As shown in direction B), the operation button 200 and the handle body 100 have at least one sealing engagement point. Thus, after the operation button 200 is movably installed in the button slot 120, pressing the operation button 200 triggers the corresponding switch 310, thereby triggering the corresponding operation command. Furthermore, because there is at least one sealing engagement point between the operation button 200 and the handle body 100 along the axial direction of the button slot 120, during surgical procedures or sterilization, it effectively prevents external substances such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life.

[0037] It should be noted that the operation button 200 can be a function button, such as an electric cut button, or a start button, such as a switch button, or other types of buttons.

[0038] Optionally, the electrode rod is inserted into the mounting cavity 110 to achieve fitting for assembly support, electrical connection, and pipeline connection. Specifically, the electrode rod is inserted into the opening 111 of the mounting cavity 110.

[0039] like Figure 4As shown, in one embodiment, the operation button 200 includes a cover 210 and a button post 220 connected to each other. The button post 220 is movably inserted through the button groove 120 and can partially extend into the mounting cavity 110. Optionally, applying pressure to the cover 210 pushes the button post 220 into the mounting cavity 110 to trigger the corresponding switch 310. The cover 210 is disposed outside the button groove 120 and is sealed to the outer wall of the handle body 100 to form a sealed mating part. In this way, the sealed mating between the cover 210 and the outer wall of the handle body 100 prevents foreign objects such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life.

[0040] Optionally, the cover 210 and the button post 220 can be integrally molded and made of elastic materials such as silicone, so that the cover 210 and the outer wall of the handle body 100 have a good fit and stronger sealing.

[0041] Alternatively, an intermediate layer such as sealant can be filled at the contact area between the cover 210 and the handle body 100 to improve the sealing effect.

[0042] Optionally, the cover 210 has a circular outline, the button groove 120 also has a circular outline, and the outer diameter of the cover 210 is larger than the diameter of the button groove 120, so that the lower side wall of the cover 210 fits against the outer side wall of the handle body 100 to achieve a seal.

[0043] like Figure 4 As shown, in one embodiment, the cover 210 is further provided with a mounting sleeve 230. The mounting sleeve 230 surrounds the button post 220 and is spaced apart from it, ensuring that the mounting sleeve 230 does not interfere with the movement of the button post 220, thus guaranteeing that the switch 310 can be accurately and stably triggered. The mounting sleeve 230 at least partially seals against the inner wall of the button groove 120, forming a sealed mating area. This surface seal is achieved by the fit between the outer wall of the mounting sleeve 230 and the inner wall of the button groove 120, effectively preventing foreign matter such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life. Furthermore, the sealing fit between the mounting sleeve 230 and the inner wall of the button groove 120, combined with the sealing fit between the cover 210 and the outer wall of the handle body 100, achieves a double seal, effectively improving the sealing effect.

[0044] Alternatively, an intermediate layer such as sealant can be filled at the contact area between the mounting sleeve 230 and the inner wall of the key slot 120 to improve the sealing effect.

[0045] like Figure 4As shown, in one embodiment, the mounting sleeve 230 is provided with a first sealing part 231, and the handle body 100 is provided with a second sealing part 130. The first sealing part 231 and the second sealing part 130 seal and cooperate to form a sealed cooperation part, which can further prevent foreign objects such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life. Moreover, the assembly connection between the mounting sleeve 230 and the handle body 100 is achieved by utilizing the sealing cooperation between the first sealing part 231 and the second sealing part 130, which can prevent the mounting sleeve 230 from moving with the button post 220, ensuring the fit between the outer wall of the mounting sleeve 230 and the inner wall of the button groove 120, and ensuring the sealing effect. Furthermore, it can work in conjunction with the aforementioned sealed cooperation part to enhance the sealing effect.

[0046] The sealing fit between the first sealing part 231 and the second sealing part 130 can be achieved through a concave-convex fit.

[0047] In one embodiment, one of the first sealing part 231 and the second sealing part 130 is a sealing groove, and the other is a sealing protrusion. The sealing protrusion is inserted into and sealed to fit the sealing groove, thereby forming a bent sealing structure. This can effectively prevent foreign objects such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life.

[0048] like Figure 4 As shown, in one embodiment, the mounting sleeve 230 further includes a bent portion 232 disposed within the mounting cavity 110. The bent portion 232 is sealed and fitted against the inner wall of the mounting cavity 110 to form a sealed mating area. This further prevents foreign matter such as blood and water from seeping into the mounting cavity 110 and damaging electrical components, thus ensuring service life. Moreover, it can work synergistically with the aforementioned sealed mating area to enhance the sealing effect. Furthermore, the bent portion 232 can be arranged parallel to the cover 210 to form a clamping structure for holding the handle body 100, enhancing assembly stability, preventing easy detachment, and further enhancing the sealing effect through a synergistic fit.

[0049] Optionally, an intermediate layer such as sealant can be filled at the contact area between the bent portion 232 and the inner wall of the mounting cavity 110 to improve the sealing effect.

[0050] like Figure 2 , Figure 3 and Figure 5As shown, in one embodiment, the operating handle 10 further includes a button control board 300, a wire 400, and a sealing sleeve 500. The button control board 300 is disposed within the mounting cavity 110 by means of a snap-fit ​​or similar method. One end of the wire 400 is electrically connected to the button control board 300, and the other end extends outside the mounting cavity 110 to electrically connect with external devices to provide power to the button control board 300 and for signal interaction. Furthermore, the sealing sleeve 500 is fitted around the outer periphery of the wire 400 and seals against the inner wall of the mounting cavity 110. This effectively prevents foreign objects such as blood and water from seeping into the mounting cavity 110 through the wire 400 and damaging electrical components, thus ensuring the service life of the components.

[0051] Optionally, the sealing sleeve 500 can be in the form of a sealing ring, and can be made of materials such as silicone or rubber.

[0052] like Figures 2 to 4 As shown, optionally, the button control panel 300 may be provided with at least one switch 310, and each switch 310 is set to a button post 220 of an operation button 200. By pressing the operation button 200, the corresponding switch 310 can be triggered to trigger the corresponding signal.

[0053] like Figure 2 and Figure 6 As shown, in one embodiment, the button control panel 300 is provided with a display unit 320. Furthermore, the handle body 100 is provided with a display window 140 corresponding to the display unit 320. The operating handle 10 also includes a transparent shield 600 disposed within the display window 140, allowing the content displayed on the display unit 320 to be viewed through the transparent shield 600. Moreover, the transparent shield 600 is sealed to the inner wall of the display window 140, effectively preventing foreign objects such as blood and water from seeping in through the transparent shield 600 and damaging the display unit 320, thus ensuring its service life.

[0054] Optionally, the display unit 320 may be a display screen or other display element.

[0055] Optionally, the transparent shield 600 can be a plate-like or cover-like structure made of transparent material.

[0056] The sealing fit between the transparent shield 600 and the inner wall of the display window 140 can be achieved by setting a sealing ring or filling with sealant. For example, a groove for installing the sealing ring or sealant can be provided on the transparent shield 600.
