Description

Technical Field

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

[0002] Plasma surgical electrodes are used in clinical surgery to perform functions such as tissue cutting, ablation, and hemostasis. A plasma surgical electrode includes a compatible operating handle and a blade structure. Current technologies offer plasma surgical electrodes with detachable and replaceable blades. After single or multiple uses, the blade structure is replaced, and the operating handle is sterilized and reused. Traditional plasma surgical electrodes, however, have an integrated suction tube in the operating handle for aspirating blood, ionized fluid, and other waste liquids. This integration fails to effectively isolate contaminants, leading to hygiene issues with repeated use and potential corrosion of internal components. Furthermore, the built-in suction tube increases the handle diameter, making it difficult to grip. Utility Model Content

[0003] Therefore, it is necessary to provide a blade structure, a plasma surgical electrode, and a plasma surgical device to address the hygiene issues and difficulties in gripping caused by the repeated use of the operating handle.

[0004] The technical solution is as follows:

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

[0006] Blade tip;

[0007] The cutter body has one end connected to the cutter head. The cutter body is provided with a liquid supply channel and a liquid suction channel, both of which extend axially and communicate with the cutter head.

[0008] A connecting housing is provided for detachable connection with the operating handle of a plasma surgical electrode. The connecting housing includes a liquid inlet channel, a suction channel, and a insertion cavity. The liquid inlet channel and the suction channel are both connected to and isolated from the insertion cavity. The other end of the blade body is inserted into the insertion cavity to connect the liquid inlet channel with the liquid supply channel and the suction channel with the liquid aspiration channel.

[0009] A suction tube is inserted into the suction channel from the outside of the connecting housing to communicate with the liquid suction channel.

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

[0011] In one embodiment, the cutter head structure further includes a liquid inlet pipe that is inserted from the outside into the liquid inlet channel to communicate with the liquid supply channel.

[0012] In one embodiment, the suction channel and / or the liquid inlet channel protrude from the outer wall of the connecting housing to form a connector structure.

[0013] In one embodiment, the suction channel and the liquid inlet channel are located on the same side of the connecting housing in the radial direction.

[0014] In one embodiment, the cutter head structure further includes an isolating member disposed within the insertion cavity, the isolating member being sleeved on the outer side wall of the cutter body; along the axial direction of the insertion cavity, the isolating member is located between the suction channel and the liquid inlet channel to block the liquid supply channel.

[0015] In one embodiment, the blade structure further includes a guide member disposed within the insertion cavity; the guide member has a guide channel connecting the suction channel and the liquid suction channel, and the guide channel is guided and engaged with the suction tube to connect the suction tube and the liquid suction channel.

[0016] In one embodiment, the outer diameter of the isolating member matches the inner diameter of the insertion cavity, the outer diameter of the guide member matches the inner diameter of the insertion cavity, the isolating member is disposed between the guide member and the liquid inlet channel, and the guide member and the isolating member abut against each other.

[0017] In one embodiment, the cutter head structure further includes an electrical unit disposed within the insertion cavity and electrically connected to the cutter bar body, and the electrical unit is electrically compatible with the operating handle.

[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 blade head structure, plasma surgical electrode, and plasma surgical device described in the above embodiments integrate the inlet channel and suction channel into the connecting housing of the blade head structure. The ionized liquid reaches the affected area through the inlet channel of the connecting housing and the supply channel of the blade body. Waste liquid generated after ionization is discharged through the suction channel of the blade body and the suction channel of the connecting housing. Replacing the blade head, blade body, and connecting housing 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. Furthermore, integrating the inlet channel and suction channel into the connecting housing instead of the operating handle reduces the risk of leakage inside the operating handle. Simultaneously, the elimination of the need for a built-in suction tube in the operating handle significantly reduces its diameter, facilitating grip. Attached Figure Description

[0028] 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.

[0029] In traditional plasma surgical electrodes, both the inlet and aspiration channels are located on the operating handle. The ionized fluid enters through the inlet channel on the handle, passes through the connecting housing in the blade head structure, and flows into the supply channel of the blade body to reach the affected area. Waste fluid enters the aspiration channel of the blade body and is suctioned out through the aspiration channel of the operating handle. Even if the blade head, blade body, and connecting housing are replaced, the relatively narrow inlet and aspiration channels in the operating handle cannot effectively or thoroughly sterilize, resulting in insufficient isolation of contaminants during repeated use and leading to hygiene problems. Furthermore, the built-in aspiration tube in the operating handle increases the handle diameter, making it difficult to grip.

[0030] like Figure 1 As shown, 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 and connected to the plasma surgical electrode, thereby enabling the plasma surgical electrode to provide power, suction and other functions.

[0031] It should be noted that the host can use existing components, which will not be elaborated here.

[0032] 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.

[0033] 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.

[0034] It should be noted that the operating handle can adopt the existing grip structure, which will not be described in detail here.

[0035] like Figures 1 to 3 As shown, in one embodiment, a blade structure 10 is provided, including a blade head, a blade holder body 100, a connecting housing 200, and a suction tube 2000.

[0036] The blade can adopt an existing structure. Depending on the type of blade, it can perform tissue cutting, ablation, and hemostasis on the affected area. These will not be elaborated or listed here.

[0037] One end of the blade body 100 is connected to the blade head. The blade body 100 is provided with a fluid supply channel 110 and a fluid suction channel 120. Both the fluid supply channel 110 and the fluid suction channel 120 extend axially and connect to the blade head, allowing the ionized fluid to reach the blade head through the fluid supply channel 110 and flow into the affected area for tissue cutting and ablation. Waste fluid can also be suctioned out from the blade head through the fluid suction channel 120. Furthermore, the fluid supply channel 110 and the fluid suction channel 120 are isolated from each other and do not communicate with each other, preventing the ionized fluid from mixing with the waste fluid and affecting the normal progress of the surgery.

[0038] Optionally, the knife holder body 100 may include an inner knife tube and an outer knife tube that are nested together. The outer side wall of the inner knife tube and the inner side wall of the outer knife tube are spaced apart to form a liquid supply channel 110, and the inner cavity of the inner knife tube forms a liquid suction channel 120.

[0039] The connecting housing 200 is detachably connected to the operating handle of the plasma surgical electrode. The connecting housing 200 has a liquid inlet channel 210, a suction channel 230, and a insertion cavity 220. The liquid inlet channel 210 and the suction channel 230 are both connected to the insertion cavity 220 but isolated from each other to prevent mixing of ionized liquid and waste liquid due to cross-contamination. The other end of the blade body 100 is inserted into the insertion cavity 220 to connect the liquid inlet channel 210 with the liquid supply channel 110 and the suction channel 230 with the liquid suction channel 120.

[0040] The suction tube 2000 is inserted into the suction channel 230 from the outside of the connecting housing 200 to communicate with the liquid suction channel 120.

[0041] In the above embodiment, the blade structure 10 integrates both the inlet channel 210 and the suction channel 230 onto the connecting housing 200. The ionized liquid reaches the affected area through the inlet channel 210 of the connecting housing 200 and the supply channel 110 of the blade body 100. Waste liquid generated after ionization is discharged through the suction channel 120 of the blade body 100 and the suction channel 230 of the connecting housing 200. Replacing the blade, blade body 100, and connecting housing 200 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. Furthermore, integrating the inlet channel 210 and suction channel 230 onto the connecting housing 200 instead of the operating handle reduces the risk of leakage inside the operating handle. Simultaneously, the absence of a built-in suction tube 200 in the operating handle significantly reduces its diameter, facilitating grip.

[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the blade structure 10 further includes a liquid inlet pipe 1000, which is inserted from the outside into the liquid inlet channel 210 to communicate with the liquid supply channel 110. Thus, external ionized liquid can be delivered to the affected area through the liquid inlet pipe 1000 via the liquid inlet channel 210 and the liquid supply channel 110.

[0043] like Figures 1 to 3 As shown, in one embodiment, the suction channel 230 and / or the liquid inlet channel 210 protrude from the outer side wall of the connecting housing 200 to form a connector structure. This facilitates the insertion and connection of the suction tube 2000 and the liquid inlet tube 1000 with the suction channel 230 and the liquid inlet channel 210 respectively, reducing assembly difficulty.

[0044] like Figures 1 to 3 As shown, in one embodiment, the suction channel 230 and the liquid inlet channel 210 are located on the same side of the connecting housing 200 in the radial direction. This allows the suction tube 2000 and the liquid inlet tube 1000 to be arranged on the same side of the connecting housing 200, avoiding interference or impact on the surgical field of view and operation.

[0045] It should be noted that the electrolytic fluid can be supplied into the inlet pipe 1000 via the main unit or other external devices. Waste liquid can be extracted from the suction pipe 2000 via the main unit or other external devices.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, the blade structure 10 further includes an isolating member 300 disposed within the insertion cavity 220, the isolating member 300 being sleeved on the outer side wall of the blade body 100. Furthermore, along the axial direction of the insertion cavity 220, the isolating member 300 is located between the suction channel 230 and the liquid inlet channel 210 to block the liquid supply channel 110. Thus, by using the isolating member 300 to block and isolate the liquid supply channel 110, cross-flow or backflow of the ionized liquid within the liquid supply channel 110 is prevented, thus avoiding interference or damage to other components, affecting surgical outcomes and service life.

[0047] The isolation element 300 can be in the form of an isolation sealing sleeve or an isolation sealing ring, as long as it can block the end of the liquid supply channel 110.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment, the blade structure 10 further includes a guide 400. The guide 400 is disposed within the insertion cavity 220 by means of snap-fit ​​or plug-in connection. Furthermore, the guide 400 has a guide channel 410 connecting the suction channel 230 and the liquid suction channel 120. The guide channel 410 guides and cooperates with the suction tube 2000 to connect the suction tube 2000 to the liquid suction channel 120. Thus, when one end of the blade body 100 is inserted into the insertion cavity 220, and the suction tube 2000 is inserted into the suction channel 230 and the guide channel 410, the guide channel 410 ensures accurate and reliable communication between the suction tube 2000 and the liquid suction channel 120, preventing leakage.

[0049] The guide component 400 can be in the form of a guide sleeve or a guide post.

[0050] 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 of the knife bar body 100 after insertion.

[0051] 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 liquid inlet channel 210, 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.

[0052] like Figures 1 to 3 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.

[0053] The electrical unit 500 can be either a pin or a socket, while the other of the pin and socket is arranged on the operating handle.
