[0002] Reusable argon electrodes, also known as argon electrodes, are accessories for medical high-frequency instruments and equipment, and are used for hemostasis and ablation of blood vessels and tissues during high-frequency surgery. Existing argon electrodes consist of a plug, an adapter tube, and an electrode tube. However, in actual use, doctors have reported that the adaptability of the specifications and models of argon electrodes in surgery plays an important role. 1. Limited range of action: Due to the small diameter of the electrode tube, the range of tissue that can be directly affected is also correspondingly small. This may not be efficient enough when dealing with large-area bleeding or areas that require extensive coagulation. 2. Difficulty of operation: The small electrode tube may require the operator to have a higher level of technical skills and precision to ensure that the high-frequency current and argon gas are accurately delivered to the target tissue. Improper operation may lead to insufficient or excessive treatment, which in turn affects the effectiveness of the surgery. Utility Model Content

[0042] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0043] This embodiment provides an argon electrode, the specific structure of which is as follows Figure 1 、 Figure 2 and Figure 3 As shown, the argon electrode includes a plug 10, a transfer tube 20 and an electrode tube 30, and the argon electrode also includes:

[0044] A first connecting portion 40 is provided at the connection between the transfer tube 20 and the electrode tube 30. The first connecting portion 40 is used to connect the transfer tube 20 and the electrode tube 30. The first connecting portion 40 includes a locking member (not shown in the figure) that is sleeved at the connection between the transfer tube 20 and the electrode tube 30.

[0045] The outer diameter of the electrode tube 30 is 1.8±0.05 mm.

[0046] Specifically, this embodiment uses an argon electrode with a total length of 4740±50 mm, a transition tube 20 with a length of 2500±20 mm, an electrode tube 30 with a length of 2200±5 mm, and a transition tube 20 diameter of 4±0.05 mm as an example. The outer diameter of the electrode tube 30 is 1.8±0.05 mm. Compared to an electrode tube 30 with an outer diameter of 1.5 mm, this increased diameter increases the effective range of the electrode tube 30, improving treatment efficiency when treating large areas of bleeding or areas requiring extensive coagulation. Furthermore, the larger electrode tube 30 does not require excessive operator skill and precision to ensure accurate delivery of high-frequency current and argon gas to the target tissue. This prevents careless operation from potentially leading to under- or over-treatment, potentially compromising surgical outcomes. It is understood that the total length of the argon electrode, the length of the transition tube 20, the length of the electrode tube 30, and the diameter of the transition tube 20 can also be other sizes, and this embodiment is not limiting.

[0047] Furthermore, in this embodiment, the plug 10, the adapter tube 20, and the electrode tube 30 are connected in sequence. It should be noted that the adapter tube 20 and the electrode tube 30 are connected via a first connector 40, allowing gas from the host gas source to flow into the electrode tube 30 through the adapter tube 20. The first connector 40 uses a locking member to lock the connection between the adapter tube 20 and the electrode tube 30, connecting them as a whole. Compared to a direct plug-and-socket connection between the adapter tube 20 and the electrode tube 30, this prevents the adapter tube 20 and the electrode tube 30 from separating and falling off, thereby improving the reliability of the argon electrode. Furthermore, the use of high-temperature and high-pressure sterilization-resistant materials allows the product to be repeatedly sterilized, allowing the argon electrode to be reused multiple times.

[0048] Furthermore, in this embodiment, the first connecting portion 40 also includes a first connecting member 41, the two ends of which extend into the adapter tube 20 and the electrode tube 30 respectively, and the locking member is sleeved on the first connecting member 41 and is used to tighten the adapter tube 20 and the electrode tube 30.

[0049] Specifically, the diameter of the adapter tube 20 differs from the outer diameter of the electrode tube 30, with the adapter tube 20 having a larger diameter than the electrode tube 30. The first connector 41 is a tube with a protrusion on its outer surface, located in the middle of its length. One end of the first connector 41 extends into the adapter tube 20, where the end of the adapter tube 20 abuts the protrusion. The other end of the first connector 41 extends into the electrode tube 30, where the end of the electrode tube 30 abuts the protrusion. Two locking members are located on either side of the protrusion, securing the outer surfaces of the adapter tube 20 and electrode tube 30 to the first connector 41 through the locking members, thereby forming a single integral structure of the adapter tube 20, electrode tube 30, and first connector 41. It should be understood that the first connector 41 has a hole for gas flow, enabling communication with the adapter tube 20 and electrode tube 30. Furthermore, the ends of the first connector 41 are adapted to fit the adapter tube 20 and electrode tube 30.

[0050] In other embodiments, the number of locking members may be one, that is, when the end of the electrode tube 30 abuts against the protrusion, the end of the adapter tube 20 is extended from the protrusion toward the electrode tube 30 to sleeve the adapter tube 20 on the outer peripheral side of the electrode tube 30. In this way, the adapter tube 20, the electrode tube 30 and the first connecting member 41 can be connected to form a whole with only one locking member.

[0051] In this embodiment, the locking member is a snap ring. The snap ring is an annular structure known in the prior art. After being sleeved onto the outer circumference of the adapter tube 20 or the electrode tube 30, the snap ring can be squeezed and deformed to tighten the adapter tube 20 and the electrode tube 30 and improve the sealing performance of the connection between the adapter tube 20 and the electrode tube 30. This is the prior art ring pressing process, which will not be described in detail here.

[0052] In this embodiment, the first connector 41 is made of metal. Due to its inherent high-temperature resistance, installing a metal first connector 41 between the adapter tube 20 and the electrode tube 30 can meet the high-temperature operation requirements of the argon electrode. Furthermore, compared to a plastic first connector 41, a metal first connector 41 improves the structural strength of the connection between the adapter tube 20 and the electrode tube 30, preventing separation or detachment.

[0053] In this embodiment, the plug 10 includes a housing 11 , in which a sleeve 12 is provided. One end of the sleeve 12 is used to communicate with the air source of the host, and the other end of the sleeve 12 is used to communicate with the transfer tube 20 .

[0054] Specifically, a cavity is formed within the housing 11, and a receiving groove is provided within the cavity to accommodate the sleeve 12 and the transfer tube 20. The sleeve 12 is snap-fitted into the receiving groove along the length of the housing 11, and the transfer tube 20 extends into the housing 11 along the length of the housing 11 and communicates with the sleeve 12, thereby allowing the host gas source to flow through the sleeve 12 into the transfer tube 20 and ultimately into the electrode tube 30. It can be understood that the housing 11 is a split structure, divided into two parts along the width direction of the housing 11, and the two parts are connected by a bolt assembly to form the housing 11. The provision of a split structure facilitates the installation of the sleeve 12, the transfer tube 20, etc. within the housing 11, improving the convenience of installation.

[0055] Furthermore, in this embodiment, a Luer connector 13 is provided between the sleeve 12 and the transfer tube 20 , and the Luer connector 13 is connected to the transfer tube 20 through the second connecting portion 50 .

[0056] Specifically, the Luer connector 13 is a conventional structure, positioned between the cannula 12 and the adapter tube 20. One end of the Luer connector 13 extends into the cannula 12, and a second connection portion 50 is provided between the other end of the Luer connector 13 and the adapter tube 20. Compared to installing a filter between the cannula 12 and the adapter tube 20, the Luer connector 13 enables the plug 10 to be reusable, thereby extending the service life of the argon electrode. Furthermore, the second connection portion 50 between the Luer connector 13 and the adapter tube 20 enhances the structural strength of the connection between the two tubes.

[0057] It is understandable that the Luer connector 13 is also embedded in the receiving groove in the housing 11, and the Luer connector 13 is positioned in the housing 11 by engaging the receiving groove with the protrusion on the outer surface of the Luer connector 13.

[0058] In this embodiment, the second connecting portion 50 includes a second connecting member 51 and a locking member (not shown in the figure). The first end of the second connecting member 51 extends into the Luer connector 13, and the second end of the second connecting member 51 extends into the transfer tube 20. The second end of the second connecting member 51 has a barb structure, and the second end of the second connecting member 51 is also provided with a groove. The locking member is sleeved on the groove and is used to tighten the transfer tube 20.

[0059] Specifically, the second connector 51 is a tube with a barb structure on its outer surface. This barb structure is conventional and will not be described in detail here. The barb structure is conical in cross-section, with the smaller end of the barb structure facing the second end of the second connector 51 and the larger end facing the first end of the second connector 51. A groove is located between the larger end of the barb structure and the first end of the second connector 51, and is located near the larger end of the barb structure. The first end of the second connector 51 is coated with glue to achieve a sealed connection between the Luer connector 13 and the first end of the second connector 51. The second end of the second connector 51 extends into the adapter tube 20, and the end of the adapter tube 20 abuts against the sidewall of the groove. When the locking member is mounted on the groove, the adapter tube 20 is tightened to the second connector 51, thereby forming a unified structure with the Luer connector 13 and the second connector 51, preventing the adapter tube 20 and Luer connector 13 from separating. It is understood that the second connecting member 51 has a hole for gas circulation therein to achieve communication with the transfer tube 20 and the Luer connector 13. In addition, both ends of the second connecting member 51 are adapted to fit the transfer tube 20 and the Luer connector 13.

[0060] In this embodiment, the second connector 51 is made of metal. Due to its inherent high-temperature resistance, installing a metal second connector 51 between the adapter tube 20 and the Luer connector 13 can meet the high-temperature operation requirements of the argon electrode. Furthermore, compared to a plastic second connector 51, a metal second connector 51 improves the structural strength of the connection between the adapter tube 20 and the Luer connector 13, preventing separation or detachment.

[0061] In this embodiment, the locking member is a snap ring. The snap ring is an annular structure known in the prior art. After being sleeved onto the outer circumference of the adapter tube 20, the snap ring can be squeezed and deformed to tighten the adapter tube 20 and the second connector 51, thereby improving the sealing performance of the connection between the adapter tube 20 and the Luer connector 13. This is known as the prior art ring compression process, which will not be described in detail here.

[0062] In this embodiment, the housing 11 is made of PEI, and the adapter tube 20 and electrode tube 30 are made of PTFE. It is understood that both PEI and PTFE are high-temperature resistant materials in the prior art. PEI has a certain hardness, making it suitable for use as the housing 11 material. PTFE, due to its flexibility, can be used as a pipe, facilitating multiple bending. This ensures the high-temperature resistance of the argon electrode and allows it to be used in various operating conditions, thus expanding its applicability.
