[0010] In one embodiment, the inner shell is further provided with a sol-gel tank corresponding to and communicating with the insertion through hole, and an injection tank located beside the sol-gel tank and communicating with the sol-gel tank.

[0011] In one embodiment, the handle further includes a tail portion connected to the inner shell and located at the rear end of the outer shell. The tail portion is provided with a first through hole for the conductive wire to pass through, a second through hole for the injection tube to pass through, and a third through hole for the suction tube to pass through. The first through hole, the second through hole, and the third through hole are all in communication with the mounting cavity.

[0012] In one embodiment, the first positioning part includes two first positioning plates arranged radially opposite to each other along the mounting cavity, the two first positioning plates cooperating to form a first positioning groove for engaging the conductive wire.

[0013] In one embodiment, the second positioning part includes two second positioning plates that are radially spaced apart from each other along the mounting cavity. The two second positioning plates cooperate to form a second positioning groove for engaging the suction tube, and the second positioning groove is corresponding to the electrode rod along the axial direction of the mounting cavity.

[0014] In one embodiment, the third positioning part includes two third positioning plates arranged radially spaced along the mounting cavity, the two third positioning plates overlapping at least partially along the radial direction of the mounting cavity to form a third positioning groove for engaging the injection tube.

[0025] 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.

[0026] like Figure 1 As shown, in one embodiment, a surgical device is provided, including a radio frequency host (not shown) and a plasma surgical electrode 10.

[0027] The radio frequency host can be an existing device that can provide at least one of the functions of high-frequency current, suction force, and ionized liquid.

[0028] Optionally, the radio frequency host can be electrically connected to the conductive wire 200 to provide high-frequency current to the electrode rod 500 of the plasma surgical electrode 10.

[0029] Optionally, the radio frequency unit can be vacuum connected to the suction tube 300 to provide vacuum suction for the aspiration of ionized liquid and ionized tissue.

[0030] Optionally, the radio frequency unit can be connected to the injection tube 400 to pump ionizing fluid for ionization removal.

[0031] In actual use, the RF host can be connected to at least one of the conductive wire 200, the suction tube 300, and the injection tube 400 to provide the corresponding function.

[0032] like Figures 1 to 4 As shown, in one embodiment, a non-detachable plasma surgical electrode 10 is provided. The plasma surgical electrode 10 includes an electrode rod 500, a conductive wire 200, an injection tube 400, a suction tube 300, and a handle 100. The electrode rod 500 is connected to the front end of the handle 100 by means of a plug-in connection or the like, and the conductive wire 200, the injection tube 400, and the suction tube 300 are connected to the rear end of the handle 100 by means of a plug-in connection or the like. The handle 100 has a mounting cavity 110 extending axially and open at both ends. Furthermore, the inner wall of the mounting cavity 110 is provided with at least one of a first positioning part 120, a second positioning part 130, and a third positioning part 140. The first positioning part 120 is used for positioning and engaging with the conductive wire 200, the second positioning part 130 is used for positioning and engaging with the suction tube 300, and the third positioning part 140 is used for positioning and engaging with the injection tube 400.

[0033] It should be noted that the front end of the handle 100 refers to the end facing the electrode tip, and the rear end of the handle 100 refers to the end away from the electrode tip, that is, the two ends of the handle 100 along the axial direction mentioned above.

[0034] The plasma surgical electrode 10 of the above embodiment is provided with at least one of a first positioning part 120, a second positioning part 130, and a third positioning part 140 on the inner wall of the mounting cavity 110. Specifically, the first positioning part 120 is used to position and engage with the conductive wire 200 to fix the conductive wire 200 relative to the handle 100; the second positioning part 130 is used to position and engage with the suction tube 300 to fix the suction tube 300 relative to the handle 100; and the third positioning part 140 is used to position and engage with the injection tube 400 to fix the injection tube 400 relative to the handle 100. This avoids the risk of rotation or detachment of the conductive wire 200, injection tube 400, and suction tube 300 relative to the handle 100, ensuring the safe and reliable conduct of the surgery.

[0035] It should be noted that the conductive wire 200, the injection tube 400, and the suction tube 300 can all use existing structures or components, which will not be described in detail here.

[0036] like Figure 2 As shown, in one embodiment, the handle 100 includes a housing 101 and an inner housing 102. The housing 101 has a mounting cavity 110, and the inner housing 102 can be inserted into the mounting cavity 110, at least partially within it. Furthermore, the inner housing 102 has at least one of a first positioning portion 120, a second positioning portion 130, and a third positioning portion 140. Thus, by machining the first positioning portion 120, the second positioning portion 130, and the third positioning portion 140 onto the inner housing 102, and then inserting the inner housing 102 into the mounting cavity 110 so that the first positioning portion 120, the second positioning portion 130, and the third positioning portion 140 are located within the mounting cavity 110, the machining difficulty is reduced.

[0037] like Figure 4 As shown, the inner shell 102 further includes spaced-apart injection holes 1021 and insertion holes 1022. Both injection holes 1021 and insertion holes 1022 communicate with the mounting cavity 110. The insertion hole 1022 engages with the electrode rod 500, allowing the electrode rod 500 to be partially located within the mounting cavity 110 and securely connected to the handle 100, thus enabling the electrode rod 500 to be electrically connected to the conductive wire 200 and energized. One end of the injection hole 1021 communicates with the electrode rod 500, and the other end communicates with the injection tube 400, allowing the injection tube 400 to inject ionized fluid into the electrode rod 500 through the injection hole 1021 for ionization cutting or hemostasis.

[0038] The electrode rod 500 can adopt an existing structure or construction. For example, the electrode rod 500 may include an outer knife tube and an inner knife tube that are sleeved together. The outer knife tube and the inner knife tube are fitted with a clearance. The inner knife tube can rotate axially relative to the outer knife tube. The injection tube 400 is connected to the gap between the outer knife tube and the inner knife tube through the injection through hole 1021.

[0039] like Figure 4 As shown, further, the inner wall of the insertion through hole 1022 is provided with at least one positioning protrusion 1023 that positions and engages with the electrode rod 500. Thus, the positioning protrusion 1023's contact with the electrode rod 500 ensures a more secure fit between the electrode rod 500 and the handle 100, preventing the electrode rod 500 from rotating relative to the handle 100 or falling off, thus ensuring a safe and reliable surgical procedure.

[0040] The specific number of positioning protrusions 1023 can be flexibly adjusted or designed according to actual usage needs or processing conditions, for example, it can be one, two, three or more.

[0041] like Figure 3 As shown, in one embodiment, the inner shell 102 is further provided with a sol-gel tank 1024 corresponding to and communicating with the insertion through hole 1022, and an injection tank 1025 located beside the sol-gel tank 1024 and communicating with the sol-gel tank 1024. In this way, after the electrode rod 500 is inserted into the mounting cavity 110 through the insertion through hole 1022, part of the electrode rod 500 is located in the sol-gel tank 1024. After the adhesive is injected into the sol-gel tank 1024 through the injection tank 1025, the electrode rod 500 and the inner shell 102 can be further stably and reliably bonded and fixed.

[0042] like Figure 2As shown, in one embodiment, the handle 100 further includes a tail portion 103. The tail portion 103 is connected to the inner shell 102 by means of snap-fit ​​or plug-in connection, and the tail portion 103 is located at the rear end of the outer shell 101, thus sealing the rear end of the mounting cavity 110. The tail portion 103 has a first through hole for the conductive wire 200 to pass through, a second through hole for the injection tube 400 to pass through, and a third through hole for the suction tube 300 to pass through. Furthermore, the first through hole, the second through hole, and the third through hole are all in communication with the mounting cavity 110. Thus, after the conductive wire 200 passes through the first through hole, it is positioned and engaged with the first positioning part 120 and electrically connected to the electrode rod 500. After the injection tube 400 passes through the second through hole, it is positioned and engaged with the second positioning part 130 and communicates with the gap between the outer and inner blade tubes of the electrode rod 500. After the suction tube 300 passes through the third through hole, it is positioned and engaged with the third positioning part 140 and communicates with the inner blade tube of the electrode rod 500. This ensures the stability of the assembly of the conductive wire 200, injection tube 400, and suction tube 300 with the handle 100, avoids the risk of the conductive wire 200, injection tube 400, and suction tube 300 rotating relative to the handle 100 or falling off, and ensures the safe and reliable performance of the surgery.

[0043] The rear end refers to the end of the handle 100 that is away from the cutter head.

[0044] The positioning and engagement between the conductive wire 200 and the first positioning part 120 can be achieved by means of snap-fit ​​or plug-in.

[0045] like Figure 3 As shown, in one embodiment, the first positioning part 120 includes two first positioning plates 121 arranged radially and relatively spaced apart along the mounting cavity 110. The two first positioning plates 121 cooperate to form a first positioning groove 122 for engaging the conductive wire 200. Thus, after the conductive wire 200 is inserted into the mounting cavity 110, it engages with the first positioning groove 122, thereby fixing the guide wire relative to the handle 100 and preventing the conductive wire 200 from rotating relative to the handle 100 or falling off.

[0046] The positioning and engagement of the suction tube 300 and the second positioning part 130 can be achieved by snap-fit ​​or plug-in connection.

[0047] like Figure 3As shown, in one embodiment, the second positioning part 130 includes two second positioning plates 131 arranged radially and relatively spaced apart along the mounting cavity 110. The two second positioning plates 131 cooperate to form a second positioning groove 132 for engaging the suction tube 300. Thus, after the suction tube 300 is inserted into the mounting cavity 110, it engages with the second positioning groove 132, thereby fixing the suction tube 300 relative to the handle 100 and preventing the suction tube 300 from rotating relative to the handle 100 or falling off. Furthermore, the second positioning groove 132 and the electrode rod 500 are correspondingly arranged along the axial direction of the mounting cavity 110. Thus, after the suction tube 300 engages with the second positioning groove 132, corresponding communication between the suction tube 300 and the inner conduit of the electrode rod 500 can be achieved.

[0048] The positioning and engagement of the injection tube 400 and the third positioning part 140 can be achieved by means of snap-fit ​​or plug-in.

[0049] like Figure 3 As shown, in one embodiment, the third positioning part 140 includes two third positioning plates 141 arranged radially spaced along the mounting cavity 110. The two third positioning plates 141 overlap at least partially along the radial direction of the mounting cavity 110 to form a third positioning groove 142 for engaging the injection tube 400. Thus, after the injection tube 400 is inserted into the mounting cavity 110, it engages with the third positioning groove 142, securing the injection tube 400 relative to the handle 100 and preventing the injection tube 400 from rotating or falling off relative to the handle 100. Furthermore, the injection tube 400 can communicate with the gap between the outer and inner blades of the electrode rod 500 through the injection through-hole 1021. Moreover, the partial overlap of the two third positioning plates 141 along the radial direction of the mounting cavity 110 extends the contact length with the injection tube 400, preventing the injection tube 400 from loosening relative to the handle 100.
