Description

Technical Field

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

[0002] Plasma surgical electrodes are widely used in clinical surgery for tissue cutting, ablation, and hemostasis. To ensure surgical safety and hygiene, some techniques involve disassembling and replacing the electrode tip after a single or limited number of uses, reusing the operating handle. To ensure the hygiene of the reusable operating handle, the injection tubing is typically integrated into the connecting housing of the tip structure, and this structure facilitates sterilization. However, because the injection tubing is inserted radially on one side of the tip structure, while the internal fluid supply channel extends axially along the electrode shaft, the two extension directions are not aligned, making alignment difficult. This design leads to leakage problems during the assembly of the electrode shaft assembly and the connecting housing. Utility Model Content

[0003] Therefore, it is necessary to provide a plasma surgical device, a plasma surgical electrode, and a blade structure to address the technical problem of easy leakage during the assembly of the blade assembly and the connecting housing.

[0004] The technical solution is as follows:

[0005] On the one hand, a cutting head structure is provided, including:

[0006] Blade tip;

[0007] A cutter body, one end of which is connected to the cutter head, the cutter body having a liquid supply channel extending axially and communicating with the cutter head, and a liquid inlet notch extending radially and communicating with the liquid supply channel at the end of the cutter body away from the cutter head; and

[0008] A connecting housing is provided for detachable connection with the operating handle of a plasma surgical electrode. The connecting housing is provided with an injection pipe and a plug-in cavity communicating with the injection pipe.

[0009] One end of the knife bar body is inserted into the insertion cavity, and the liquid inlet is connected to the liquid outlet of the injection pipe.

[0010] The technical solution will be further explained below:

[0011] In one embodiment, the cutter body includes an inner cutter tube and an outer cutter tube. The outer cutter tube is sleeved on the outer periphery of the inner cutter tube and spaced apart from the inner cutter tube to form the liquid supply channel. The outer cutter tube is provided with the liquid inlet notch.

[0012] In one embodiment, at least two liquid inlet notches are provided along the circumferential direction of the outer blade tube, and one of the liquid inlet notches is connected to the liquid outlet of the injection pipe.

[0013] In one embodiment, one side of the liquid inlet extends to the rear end of the outer blade tube.

[0014] In one embodiment, the cutter head structure further includes an isolating member disposed within the insertion cavity and sealing the liquid supply channel and the liquid inlet.

[0015] In one embodiment, the connecting housing is further provided with a suction pipe communicating with the insertion cavity, and the inner knife tube is provided with a suction channel extending axially. The suction channel is correspondingly communicated with the suction pipe, and the suction channel is isolated from the liquid supply channel.

[0016] In one embodiment, the suction pipe and the injection pipe are located on the same side of the connecting housing.

[0017] In one embodiment, the blade structure further includes a guide and a suction tube. The guide is disposed within the insertion cavity. Along the axial direction of the insertion cavity, the guide is located between the inner blade tube and the suction tube. The guide has a guide channel connecting the suction tube and the suction channel. The suction tube is inserted into the suction tube from the outside of the connecting housing. The guide channel guides and cooperates with the suction tube to connect the suction tube and the suction channel.

[0018] On the other hand, a plasma surgical electrode is provided, including an operating handle and the aforementioned blade structure, wherein the operating handle is detachably connected to the connecting housing.

[0019] In another aspect, a plasma surgical device is provided, including a main unit and the plasma surgical electrode, wherein the main unit and the plasma surgical electrode are adapted and connected.

[0020] The plasma surgical device, plasma surgical electrode, and blade structure of the above embodiments, by providing a radially extending liquid inlet notch on the blade body, can achieve corresponding communication with the liquid outlet of the injection pipe after the blade body and the connecting housing are assembled and connected. This allows the ionized liquid in the injection pipe to enter the liquid supply channel through the liquid outlet, avoiding the leakage problems caused by the radially arranged injection pipe and the axially arranged liquid supply channel not being in the same direction in the prior art.

[0031] 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.

[0032] In one embodiment, a plasma surgical device is provided, including a main unit (not shown) and a plasma surgical electrode, wherein the main unit is adapted to the plasma surgical electrode, thereby providing at least electrical energy and liquid supply to the plasma surgical electrode.

[0033] It should be noted that the host can use existing components, which will not be elaborated here.

[0034] like Figure 1 and Figure 3 As shown, in one embodiment, a plasma surgical electrode is provided, including an operating handle (not shown) and a blade structure 10. The operating handle and the blade structure 10 are detachably connected to each other, so that the operating handle can be held and the blade structure 10 can be used to perform tissue cutting, ablation and hemostasis on the affected area.

[0035] Optionally, the cutter head structure 10 and the operating handle can be detachably connected by means of plug-in or snap-fit. Since existing detachable structures can be used, they will not be described in detail here.

[0036] It should be noted that the operating handle can adopt the existing structure, which will not be described in detail here.

[0037] like Figures 1 to 6 As shown, in one embodiment, a cutting head structure 10 is provided, including a cutting head 160, a cutting shank body 100, and a connecting housing 200.

[0038] The blade 160 can adopt an existing structure. Depending on the type of blade 160, it can perform tissue cutting, ablation, and hemostasis on the affected area. These will not be elaborated or listed here.

[0039] like Figure 4 As shown, one end of the cutter body 100 is connected to the cutter head 160. The cutter body 100 is provided with a liquid supply channel 110 that extends axially and communicates with the cutter head 160. The end of the cutter body 100 away from the cutter head 160 is provided with a liquid inlet 120 that extends radially. The liquid inlet 120 is in communication with the liquid supply channel 110, so that the ionized liquid can enter the liquid supply channel 110 through the liquid inlet 120.

[0040] like Figures 1 to 4 As shown, the connecting housing 200 is detachably connected to the operating handle of the plasma surgical electrode. The connecting housing 200 is provided with an injection pipe 210 and a insertion cavity 220 communicating with the injection pipe 210. When one end of the scalpel body 100 is inserted into the insertion cavity 220 to achieve insertion and engagement, the liquid inlet notch 120 is correspondingly connected to the liquid outlet of the injection pipe 210.

[0041] In order to communicate with external liquid injection equipment (such as the main unit), the liquid injection pipe 210 can be connected to the external liquid injection equipment through components such as the liquid injection pipe 1000.

[0042] Optionally, the insertion cavity 220 extends axially to facilitate the insertion of one end of the tool holder body 100 into the insertion cavity 220 for assembly connection.

[0043] Optionally, the injection conduit 210 extends radially to facilitate the injection of ionized liquid into the injection conduit 210.

[0044] The cutter head structure 10 of the above embodiment has a radially extending liquid inlet notch 120 on the cutter body 100. When the cutter body 100 and the connecting housing 200 are assembled and connected, the liquid inlet notch 120 can be connected to the liquid outlet of the liquid injection pipe 210, so that the ionized liquid in the liquid injection pipe 210 can enter the liquid supply channel 110 through the liquid outlet, avoiding problems such as leakage.

[0045] In traditional connecting housings 200, because the injection pipe 210 extends radially or approximately radially while the supply channel 110 of the tool holder body 100 extends axially, the extension trajectories of the injection pipe 210 and the supply channel 110 are not on the same straight line. Therefore, when the tool holder body 100 is inserted axially into the insertion cavity 220 of the connecting housing 200, the supply channel 110 and the outlet of the injection pipe 210 cannot be reliably aligned and connected, easily leading to leakage. This embodiment addresses this by creating a radially extending inlet notch 120 on the tool holder body 100. This inlet notch 120 connects the supply channel 110 and the injection pipe 210, ensuring accurate alignment and connection between their outlets, effectively preventing leakage.

[0046] like Figure 4As shown, in one embodiment, the cutter body 100 includes an inner cutter tube 140 and an outer cutter tube 130. The outer cutter tube 130 is sleeved on the outer periphery of the inner cutter tube 140. Furthermore, the inner wall of the outer cutter tube 130 and the outer wall of the inner cutter tube 140 are spaced apart to form a liquid supply channel 110. The outer cutter tube 130 also has a liquid inlet notch 120. Thus, the inner cutter tube 140 and the outer cutter tube 130 can be assembled into a single unit, and one end of this unit can be inserted into the insertion cavity 220 of the connecting housing 200. This allows the liquid inlet notch 120 on the outer cutter tube 130 to communicate with the outlet of the injection pipe 210, enabling the ionized liquid to flow radially through the injection pipe 210 and the liquid inlet notch 120 into the liquid supply channel 110, thus preventing leakage.

[0047] like Figure 5 As shown, in one embodiment, at least two liquid inlet notches 120 are provided along the circumferential direction of the outer blade tube 130, and one of the liquid inlet notches 120 is connected to the outlet of the liquid injection pipe 210. In this way, the ionized liquid flowing out of the outlet of the liquid injection pipe 210 flows into the corresponding liquid inlet notch 120 and enters the liquid supply channel 110. Then, through the other liquid inlet notches 120, the ionized liquid can be more evenly distributed in the liquid supply channel 110, avoiding uneven distribution problems, ensuring uniform liquid output, and ensuring ionization effect.

[0048] It should be noted that the specific number of liquid inlet notches 120 can be flexibly adjusted or designed according to actual design or usage needs. For example, there can be two liquid inlet notches 120 arranged symmetrically in the radial direction, three liquid inlet notches 120 evenly distributed, or four or more.

[0049] like Figure 5 As shown, in one embodiment, one side of the liquid inlet notch 120 extends to the rear end of the outer blade tube 130, thereby forming an opening structure at the rear end of the outer blade tube 130. This not only facilitates the processing of the liquid inlet notch 120, but also allows the ionized liquid flowing out of the liquid outlet of the liquid injection pipe 210 to enter the liquid supply channel 110 more smoothly through the liquid inlet notch 120, improving the smoothness of liquid injection and reducing the risk of leakage.

[0050] It should be noted that the rear end of the outer blade tube 130 refers to the end that is inserted into the insertion cavity 220, that is, the end away from the blade head.

[0051] like Figures 1 to 4As shown, in one embodiment, the cutter head structure 10 further includes an isolating member 300. The isolating member 300 is disposed within the insertion cavity 220 by means of insertion or snap-fit. Furthermore, the isolating member 300 blocks the liquid supply channel 110 and the liquid inlet 120, thereby preventing ionized liquid from flowing into the insertion cavity 220 at the liquid supply channel 110 and the liquid inlet 120, thus preventing backflow or leakage.

[0052] like Figure 4 As shown, optionally, the insulating member 300 can be sleeved on the outer wall of the inner knife tube 140 and abut against the end of the outer knife tube 130 to seal it, thereby blocking and sealing the liquid supply channel 110 and the liquid inlet 120.

[0053] The insulating element 300 can be in the form of a sealing ring or a sealing sleeve.

[0054] like Figure 4 As shown, in one embodiment, the connecting housing 200 is further provided with a suction pipe 230 communicating with the insertion cavity 220, and the inner blade tube 140 is provided with a suction channel 150 extending axially. One end of the blade body 100 is inserted into the insertion cavity 220, the suction channel 150 is correspondingly connected to the suction pipe 230, and the suction channel 150 is isolated from the liquid supply channel 110 and not connected to it, so that the supply of ionized liquid and the extraction of waste liquid do not interfere with or affect each other. Thus, when one end of the blade body 100 is inserted into the insertion cavity 220 and one end of the inner blade tube 140 is inserted into the insertion cavity 220, the suction channel 150 and the suction pipe 230 are connected, allowing waste liquids such as blood and ionized liquid to be extracted through the suction channel 150 and the suction pipe 230. Furthermore, since the suction pipe 230 is integrated into the connecting housing 200 of the blade structure 10, compared to the traditional form where the suction pipe 230 is integrated into the operating handle, replacing the entire blade structure 10 allows for effective or thorough sterilization of the operating handle, effectively isolating contaminants. Even if the operating handle is reused, there are no hygiene issues. Simultaneously, integrating the suction pipe 230 into the connecting housing 200 instead of the operating handle reduces the risk of leakage from inside the operating handle.

[0055] In order to achieve a vacuum connection with an external suction device (such as the main unit), the suction pipe 230 can be connected to the external suction device through components such as the suction pipe 2000.

[0056] like Figure 6As shown, in one embodiment, the aspiration tube 230 and the injection tube 210 are located on the same side of the connecting housing 200. This allows the aspiration tube 2000 and the injection tube 1000 to be arranged on the same side of the connecting housing 200, avoiding interference or impact on the surgical field of vision and operation.

[0057] like Figure 3 and Figure 4 As shown, in one embodiment, the cutter head structure 10 further includes a guide member 400 and a suction tube 2000. The guide member 400 is disposed within the insertion cavity 220 by means of snap-fit ​​or insertion. Furthermore, along the axial direction of the insertion cavity 220, the guide member 400 is located between the cutter body 100 and the suction tube 230. The guide member 400 has a guide channel 410 connecting the suction tube 230 and the suction channel 150. The suction tube 2000 is inserted into the suction tube 230 from the outside of the connecting housing 200. The guide channel 410 and the suction tube 2000 are guided and engaged to connect the suction tube 2000 with the suction channel 150. Thus, when one end of the blade body is inserted into the insertion cavity 220, allowing the inner blade tube 140 to be inserted into the insertion cavity 220, the suction tube 2000 is inserted into the suction pipe 230 and the guide channel 410. Under the guidance of the guide channel 410, the suction tube 2000 can achieve accurate and reliable communication with the suction channel 150, preventing leakage. Simultaneously, the suction tube 2000 is inserted into the suction pipe 230 of the connecting housing 200, integrating the suction pipe 230 onto the connecting housing 200 instead of the operating handle. Compared to the prior art where the suction tube 2000 is located inside the operating handle 100, this reduces the risk of leakage inside the operating handle and also significantly reduces the diameter of the operating handle, making it easier to grip.

[0058] The guide component 400 can be in the form of a guide sleeve or a guide post.

[0059] Optionally, the guide channel 410 can be axially inclined relative to the insertion cavity 220, so that the suction tube 2000 can be easily connected to the end of the inner knife tube 140 of the knife bar body 100 after insertion.

[0060] In one embodiment, the outer diameter of the isolating member 300 is matched with the inner diameter of the insertion cavity 220 using an interference fit or other assembly method. This ensures a tight fit between the isolating member 300 and the connecting housing 200, preventing sealing failure. The outer diameter of the guide member 400 is matched with the inner diameter of the insertion cavity 220 using an interference fit or other assembly method. The isolating member 300 is disposed between the guide member 400 and the outer knife tube 130, and the guide member 400 and the isolating member 300 are in abutting fit. Thus, the isolating member 300 is used to position the guide member 400 during installation, and the guide member 400 also abuts against the isolating member 300, making the sealing effect of the isolating member 300 on the liquid supply channel 110 more stable and reliable.

[0061] like Figures 1 to 4 As shown, in one embodiment, the cutter head structure 10 further includes an electrical unit 500. The electrical unit 500 is disposed within the insertion cavity 220 and electrically connected to the cutter bar body 100 via a plug-in or snap-fit ​​method. Furthermore, the electrical unit 500 is electrically compatible with the operating handle. Thus, electrical energy can be transmitted to the cutter bar body 100 via the operating handle, and a detachable assembly connection between the cutter head structure 10 and the operating handle can be achieved.

[0062] The electrical unit 500 can be either a pin or a socket, while the other pin or socket is arranged on the operating handle.
