Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a plasma surgical device and plasma surgical equipment. Background Technology

[0002] Plasma surgical devices are widely used in clinical surgery for procedures such as tissue cutting, ablation, and hemostasis. However, after a single or limited number of uses, the entire surgical apparatus (including the handle and electrodes) needs to be replaced, resulting in high operating costs. Traditionally, only the electrodes are replaced, while the handle is reused. To facilitate sterilization of the reused handle, functional tubing (such as water injection and suction tubes) is not located on the handle; instead, interfaces are placed around the electrodes to connect to these tubing. However, this design easily leads to confusion or tangling of the tubing, affecting surgical procedures. Summary of the Invention

[0003] Therefore, it is necessary to provide a plasma surgical device and plasma surgical equipment to address the technical problems affecting surgical procedures.

[0004] The technical solution is as follows:

[0005] On the one hand, a plasma surgical device is provided, comprising:

[0006] A handle, wherein a first functional conduit is provided within the handle;

[0007] An electrode includes an electrode head, an electrode rod, and an electrode base. The electrode head is disposed at one end of the electrode rod, and the electrode base is disposed at the other end of the electrode rod. The electrode base contains a second functional conduit, and one end of the electrode base is detachably compatible with one end of a handle.

[0008] A docking assembly is movably disposed on one of the handle and the electrode base, and the docking assembly is provided with a first communication channel; the docking assembly is configured to move to a target position when the handle is adapted to the electrode, and at the target position, to connect the first functional pipeline and the second functional pipeline through the first communication channel.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the handle includes a first housing, with the first functional conduit partially passing through the first housing, and a first docking end provided at one end of the first housing; the electrode base includes a second housing, with the second functional conduit partially passing through the second housing, and a second docking end provided at one end of the second housing; the docking assembly is axially movably disposed on one of the first housing and the second housing; the docking assembly is configured such that when the first docking end and the second docking end are docked, the docking assembly can move to the target position where both the first functional conduit and the second functional conduit are partially inserted into the first communicating channel.

[0011] In one embodiment, the docking assembly is axially movably disposed on one of the first housing and the second housing, the other of the first housing and the second housing is provided with a first locking part, and the docking assembly is provided with a second locking part; when the docking assembly moves to the target position, the second locking part and the first locking part are detachably locked together.

[0012] In one embodiment, the docking assembly includes a locking sleeve having a first communicating channel, a second housing having a first sliding portion extending axially, a second sliding portion having a second sliding portion that slidably engages with the first sliding portion, a second locking portion having a side of the locking sleeve near the first housing, and the first locking portion having an inner sidewall of the first housing; the docking assembly is configured such that when the first docking end docks with the second docking end, the locking sleeve can move axially to insert into the first docking end such that both the first functional conduit and the second functional conduit are partially inserted into the first communicating channel, thereby enabling communication between the first functional conduit and the second functional conduit.

[0013] In one embodiment, the lock sleeve has an operating part on the side opposite to the second housing for operating the movement of the lock sleeve.

[0014] In one embodiment, a limiting portion is provided at one end of the second outer shell near the first outer shell. When the locking sleeve is axially limited by the limiting portion, the second locking portion is detachably locked with the first locking portion.

[0015] In one embodiment, the handle is further provided with a third functional conduit, the electrode holder is further provided with a fourth functional conduit, the docking assembly is provided with a second communication channel isolated from the first communication channel, and the docking assembly is configured to be able to move to the target position when the handle is adapted to the electrode, and at the target position, the third functional conduit and the fourth functional conduit are connected through the second communication channel.

[0016] In one embodiment, the inner wall of the first connecting channel is provided with a first sealing part, which is in sealing cooperation with the outer wall of the first functional pipeline and the outer wall of the second functional pipeline.

[0017] And / or the inner wall of the second connecting channel is provided with a second sealing part, which is in sealing cooperation with the outer wall of the third functional pipeline and the outer wall of the fourth functional pipeline.

[0018] In one embodiment, the outer wall of the first functional pipeline and the outer wall of the second functional pipeline are both provided with a third sealing part that seals with the first sealing part.

[0019] The outer walls of both the third and fourth functional pipelines are provided with a fourth sealing part that seals with the second sealing part.

[0020] On the other hand, a plasma surgical device is provided, including an energy host and the plasma surgical apparatus, wherein the energy host is connected to the plasma surgical apparatus and is used to deliver energy to the electrode head.

[0021] The plasma surgical device and equipment described in the above embodiments, when surgery is required, adapt one end of the electrode holder to one end of the handle. By moving the docking component to the target position, the first connecting channel connects the first functional pipeline and the second functional pipeline, thereby providing the corresponding functions during the surgery and ensuring the normal progress of the surgery. Furthermore, since the first functional pipeline is installed inside the handle and the second functional pipeline is installed inside the electrode, problems such as confusion or tangling caused by exposed functional pipelines are avoided, resulting in cleaner wiring, easier surgical operation, and no impact on surgical outcomes. Simultaneously, after the surgery is completed, only one end of the electrode needs to be detached from one end of the handle for individual electrode replacement, saving on usage costs.

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention 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 thorough understanding of the present invention. However, the present invention can be practiced 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 the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] In one embodiment, a plasma surgical device is provided, including an energy host (not shown) and a plasma surgical apparatus. The energy host is connected to the plasma surgical apparatus, thereby enabling the delivery of energy to the plasma surgical apparatus.

[0038] It should be noted that the power source can be an existing device, which will not be elaborated on here.

[0039] like Figures 1 to 8 As shown, in one embodiment, a plasma surgical device is provided, including a handle 100, an electrode 200, and a docking assembly 300.

[0040] like Figures 1 to 2 As shown, the handle 100 is provided with a first functional pipeline 110.

[0041] Specifically, the handle 100 has an internal cavity, and the first functional pipeline 110 passes through the internal cavity and can be fixed by means of snap-fit ​​or plug-in.

[0042] The handle 100 can be held by the operator during the operation. Various function buttons can be integrated on the handle 100. Since it is existing technology, it will not be described in detail here.

[0043] like Figure 1 and Figure 8 As shown, electrode 200 includes an electrode head 240, an electrode rod 250, and an electrode base. The electrode head 240 is located at one end of the electrode rod 250, and the electrode base is located at the other end. The energy source can sequentially supply energy to the electrode head 240 through the electrode base and electrode rod 250. Furthermore, the electrode base contains a second functional conduit 210. Moreover, one end of the electrode base can be detachably adapted to one end of the handle 100 via a plug-in or snap-fit ​​connection, allowing the electrode 200 to be assembled and connected to the handle 100 for surgical procedures.

[0044] The second functional conduit 210 extends through the electrode rod 250 to one end of the electrode head 240, and can provide one of the functions of liquid injection and aspiration for the electrode head 240.

[0045] It should be noted that the adaptation of the electrode holder to the handle 100 also includes electrical adapters and other components, which are existing technologies and will not be described or limited here.

[0046] Specifically, the electrode holder has an internal cavity, and the second functional pipeline 210 passes through the internal cavity and can be fixed by means of snap-fit ​​or plug-in.

[0047] Among them, the electrode head 240 can perform tissue cutting, ablation and hemostasis at the surgical site during the operation.

[0048] like Figures 1 to 4 As shown, the docking component 300 is movably disposed on one of the handle 100 and the electrode holder, and the docking component 300 is provided with a first communication channel 311. Furthermore, the docking component 300 is configured to move to a target position when the handle 100 and the electrode 200 are adapted. Moreover, when in the target position, the docking component 300 connects the first functional conduit 110 and the second functional conduit 210 through the first communication channel 311.

[0049] It should be noted that after the first functional line 110 is connected to the second functional line 210, it can provide one of the functions of liquid injection and aspiration for the plasma surgical device.

[0050] In the plasma surgical device described above, when surgery is required, one end of the electrode holder is adapted to one end of the handle 100. By moving the docking component 300 to the target position, the first connecting channel 311 connects the first functional conduit 110 and the second functional conduit 210, thereby providing corresponding functions during the surgery and ensuring its normal progress. Furthermore, since the first functional conduit 110 is installed inside the handle 100 and the second functional conduit 210 is installed inside the electrode 200, problems such as confusion or tangling caused by exposed functional conduits are avoided, resulting in cleaner tubing, easier surgical operation, and no impact on surgical outcomes. Simultaneously, after the surgery is completed, only one end of the electrode 200 needs to be detached from one end of the handle 100 for individual replacement, saving on usage costs.

[0051] like Figures 1 to 3As shown, in one embodiment, the handle 100 includes a first housing 120, with the first functional conduit 110 partially passing through the first housing 120, and a first docking end 121 provided at one end of the first housing 120. The electrode holder includes a second housing 220, with the second functional conduit 210 partially passing through the second housing 220, and a second docking end 221 provided at one end of the second housing 220. The docking assembly 300 is axially movably disposed on one of the first housing 120 and the second housing 220. Furthermore, the docking assembly 300 is configured such that when the first docking end 121 and the second docking end 221 are docked, the docking assembly 300 can move to a target position where both the first functional conduit 110 and the second functional conduit 210 are partially inserted into the first communicating channel 311. Thus, when one end of the first outer shell 120 is adapted to connect with one end of the second outer shell 220, the first docking end 121 and the second docking end 221 are adapted to connect and communicate. Then, the docking assembly 300 is moved to the target position, so that one end of the first functional tube 110 and one end of the second functional tube 210 are inserted into the first connecting channel 311. This allows the first functional tube 110 and the second functional tube 210 to communicate through the first connecting channel 311, providing the corresponding functions during the surgery and ensuring its normal progress. Furthermore, since one end of the first functional tube 110 and one end of the second functional tube 210 are both inserted into the first connecting channel 311, and the remaining part of the first functional tube 110 is installed in the handle 100, while the remaining part of the second functional tube 210 is installed in the electrode 200, problems such as confusion or tangling caused by exposed functional tubes are avoided. The tubing is cleaner, facilitating surgical operation and not affecting the surgical outcome. Meanwhile, once the surgery is completed, the electrode 200 can be replaced individually by simply disassembling one end of the first outer shell 120 and one end of the second outer shell 220, thus saving on usage costs.

[0052] like Figure 4 , Figure 6 and Figure 10As shown, in one embodiment, the docking assembly 300 is axially movably disposed on one of the first housing 120 and the second housing 220, the other of which is provided with a first locking part 122. The docking assembly 300 is provided with a second locking part 312. When the docking assembly 300 moves to the target position, the second locking part 312 and the first locking part 122 are detachably locked together. Thus, through the locking engagement between the first locking part 122 and the second locking part 312, the docking assembly 300 is stably and reliably held in the target position, enabling stable and reliable communication between the first functional conduit 110 and the second functional conduit 210, preventing loosening or leakage during the operation. Furthermore, after the operation is completed, the docking assembly 300 can be moved again simply by releasing the lock between the first locking part 122 and the second locking part 312, allowing the handle 100 and the electrode 200 to be separated, facilitating the individual replacement of the electrode 200.

[0053] The detachable locking engagement between the first locking part 122 and the second locking part 312 can be achieved through plug-in engagement or snap-fit ​​engagement, as long as it can satisfy both stable locking connection and easy disassembly.

[0054] In one embodiment, the first locking part 122 includes a latching protrusion, and the second locking part 312 includes a latching groove, wherein the latching protrusion can be detachably latched with the latching groove.

[0055] In one embodiment, the first locking part 122 includes a slot, and the second locking part 312 includes a pin that can be detachably engaged with the slot.

[0056] The docking component 300 can be flexibly and movablely mounted on either the first housing 120 or the second housing 220, depending on the actual design or usage, without limitation. The docking component 300 can be movable in either a sliding or rolling manner, as long as it connects the first functional conduit 110 and the second functional conduit 210 through the first connecting channel 311.

[0057] like Figure 4 , Figure 9 and Figure 10As shown, in one embodiment, the docking assembly 300 includes a locking sleeve 310, which has a first communicating channel 311. The second outer shell 220 has a first sliding portion 222 extending axially, and the locking sleeve 310 has a second sliding portion 313 that slidably engages with the first sliding portion 222. Thus, through the sliding engagement between the first sliding portion 222 and the second sliding portion 313, the locking sleeve 310 is movably mounted on the second outer shell 220. Furthermore, the locking sleeve 310 has a second locking portion 312 on the side near the first outer shell 120, and the first locking portion 122 is provided on the inner sidewall of the first outer shell 120. Furthermore, the docking assembly 300 is configured such that when the first docking end 121 docks with the second docking end 221, the locking sleeve 310 can move axially to be inserted into the first docking end 121, so that both the first functional pipe 110 and the second functional pipe 210 are partially inserted into the first connecting channel 311, thereby enabling the first functional pipe 110 and the second functional pipe 210 to communicate. When one end of the first outer shell 120 is adapted to be connected to one end of the second outer shell 220, the first mating end 121 and the second mating end 221 are adapted to be connected. Then, the locking sleeve 310 is moved axially toward the first outer shell 120 until it is inserted into the first mating end 121 and the first functional tube 110 is partially inserted into the first connecting channel 311. At this time, the second functional tube 210 is partially inserted into the first connecting channel 311. The first locking part 122 and the second locking part 312 lock together, so that the first functional tube 110 and the second functional tube 210 can be stably and reliably connected through the first connecting channel 311, thereby providing corresponding functions for the operation and ensuring the normal operation of the operation. Furthermore, since one end of the first functional tube 110 and one end of the second functional tube 210 are both inserted into the first connecting channel 311, and the remaining part of the first functional tube 110 is installed in the handle 100, while the remaining part of the second functional tube 210 is installed in the electrode 200, problems such as confusion or tangling caused by exposed functional tubes are avoided. The tubing is neater, facilitating surgical operation and not affecting the surgical outcome. Simultaneously, after the surgery is completed, simply separating the first locking part 122 from the second locking part 312 allows the locking sleeve 310 to be axially reset. Then, disassembling one end of the first outer shell 120 from one end of the second outer shell 220 allows for individual replacement of the electrode 200, saving on usage costs.

[0058] like Figure 10 As shown, in one embodiment, the locking sleeve 310 has an operation part 314 for moving the locking sleeve 310 on the side opposite to the second housing 220. Thus, the locking sleeve 310 can be moved easily and conveniently by operating the operation part 314.

[0059] The operating unit 314 can be in the form of a paddle or a pusher, as long as it is easy to move.

[0060] like Figure 9 As shown, in one embodiment, the second outer shell 220 has a limiting part 223 at one end near the first outer shell 120. When the locking sleeve 310 is axially limited by the limiting part 223, the second locking part 312 is detachably locked by the first locking part 122. Thus, by limiting the movement range of the locking sleeve 310 by the limiting part 223, when the locking sleeve 310 moves to the axially limited position of the limiting part 223, the first locking part 122 can accurately and reliably lock with the second locking part 312, ensuring stable and reliable communication between the first functional conduit 110 and the second functional conduit 210, and preventing loosening or leakage during surgery.

[0061] The axial limiting engagement between the limiting part 223 and the locking sleeve 310 can be achieved through methods such as contact, magnetic attraction, or blocking. For example, the limiting part 223 has a limiting boss, and the axial limiting is achieved by the limiting boss contacting the end face of the locking sleeve 310.

[0062] like Figures 1 to 3 , Figure 5 and Figure 8 As shown, in one embodiment, the handle 100 is further provided with a third functional conduit 130, the electrode holder is further provided with a fourth functional conduit 230, and the docking assembly 300 is provided with a second connecting channel 315 isolated from the first connecting channel 311. The docking assembly 300 is configured to move to the target position when the handle 100 is adapted to the electrode 200, and at the target position, the third functional conduit 130 and the fourth functional conduit 230 are connected through the second connecting channel 315. Thus, by adapting one end of the electrode 200 to one end of the handle 100, and by moving the docking assembly 300 to the target position so that the second connecting channel 315 connects the third functional conduit 130 and the fourth functional conduit 230, the corresponding functions can be provided during the surgical procedure, ensuring the normal progress of the surgery. Furthermore, since the third functional tube 130 is installed inside the handle 100 and the fourth functional tube 230 is installed inside the electrode 200, problems such as confusion or knotting caused by exposed functional tubes are avoided. The tubing is neater, making surgical operation easier and not affecting the surgical outcome.

[0063] When the first connecting channel 311 connects the first functional pipeline 110 and the second functional pipeline 210, the second connecting channel 315 connects the third functional pipeline 130 and the fourth functional pipeline 230.

[0064] It should be noted that after the third functional line 130 is connected to the fourth functional line 230, it can provide one of the functions of liquid injection and aspiration for the plasma surgical device.

[0065] In one embodiment, the first functional conduit 110, when connected to the second functional conduit 210, can provide the aspiration function for the plasma surgical device; the third functional conduit 130, when connected to the fourth functional conduit 230, can provide the injection function for the plasma surgical device.

[0066] In one embodiment, the first functional conduit 110, when connected to the second functional conduit 210, can provide the function of liquid injection for the plasma surgical device; the third functional conduit 130, when connected to the fourth functional conduit 230, can provide the function of suction for the plasma surgical device.

[0067] It should be noted that when a certain function is not required, the corresponding pipeline can be blocked. For example, when the function of connecting the first functional pipeline 110 and the second functional pipeline 210 is not required, the first functional pipeline 110 and the second functional pipeline 210 can be blocked; when the function of connecting the third functional pipeline 130 and the fourth functional pipeline 230 is not required, the third functional pipeline 130 and the fourth functional pipeline 230 can be blocked.

[0068] like Figure 5 As shown, in one embodiment, the inner wall of the first connecting channel 311 is provided with a first sealing part 3111, which seals against the outer walls of the first functional pipeline 110 and the second functional pipeline 210. Thus, the first sealing part 3111 ensures that there will be no leakage of liquid or air between the first functional pipeline 110 and the second functional pipeline 210.

[0069] In one embodiment, the outer wall of both the first functional conduit 110 and the outer wall of the second functional conduit 210 are provided with a third sealing part that seals with the first sealing part 3111. Thus, the sealing cooperation between the first sealing part 3111 and the third sealing part further ensures that there will be no leakage of liquid or air between the first functional conduit 110 and the second functional conduit 210.

[0070] The first sealing part 3111 can be in the form of an elastic sealing ring, etc., as long as it does not cause leakage of liquid or air.

[0071] The sealing fit between the first sealing part 3111 and the third sealing part can be achieved by a concave-convex fit, which not only ensures the sealing performance but also prevents accidental detachment.

[0072] like Figure 5 As shown, in one embodiment, the inner wall of the second communication channel 315 is provided with a second sealing part 3151, which is sealed to the outer walls of the third functional pipeline 130 and the fourth functional pipeline 230. Thus, the second sealing part 3151 ensures that there will be no leakage of liquid or air between the third functional pipeline 130 and the fourth functional pipeline 230.

[0073] In one embodiment, the outer walls of both the third functional conduit 130 and the fourth functional conduit 230 are provided with a fourth sealing portion that seals against the second sealing portion 3151. Thus, the sealing fit between the second sealing portion 3151 and the fourth sealing portion further ensures that the connection between the third functional conduit 130 and the fourth functional conduit 230 will not leak liquid or air.

[0074] The second sealing part 3151 can be in the form of an elastic sealing ring, etc., as long as it does not cause leakage of liquid or air.

[0075] The sealing fit between the second sealing part 3151 and the fourth sealing part can be achieved through a concave-convex fit, which not only ensures the sealing performance but also prevents accidental detachment.

[0076] It should be noted that "a certain body" or "a certain part" can be a portion of the corresponding "component," meaning that "a certain body" or "a certain part" is integrally formed and manufactured with the "other parts of the component"; or it can be an independent component that can be separated from the "other parts of the component," meaning that "a certain body" or "a certain part" can be manufactured independently and then combined with the "other parts of the component" to form a whole. The expression of "a certain body" or "a certain part" in this application is only one embodiment for ease of reading, and is not intended to limit the scope of protection of this application.

The term "and / or" used in this invention includes any and all combinations of one or more of the related listed items.

[0079] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixed transmission connection" to another component, the two can be fixed in a detachable or non-detachable manner, as long as power transmission can be achieved, such as sleeve, snap-fit, integral molding, welding, etc., which can be achieved in the prior art and will not be elaborated here. When a component is perpendicular or approximately perpendicular to another component, it means that the two are ideally perpendicular, but due to the influence of manufacturing and assembly, there may be a certain degree of perpendicularity error. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0083] It should also be understood that, in interpreting the connection or positional relationships of components, although not explicitly described, connection and positional relationships are interpreted to include a range of error, which should be within the acceptable deviation range of a specific value as determined by a person skilled in the art. For example, "approximately," "about," or "substantially" can mean within one or more standard deviations, without limitation herein.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
