Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a high-frequency electrosurgical leakage current detection device. Background Technology

[0002] A high-frequency electrosurgical unit leakage current detection device is used to monitor for leakage current during high-frequency electrosurgical procedures, aiming to ensure surgical safety. However, this device has several problems affecting its detection accuracy and reliability. First, improper installation of the high-frequency current transformer between the high-frequency electrosurgical unit and the leakage current detection device can prevent the leakage current signal from being accurately captured, thus affecting the detection results. Second, there may be tiny gaps at the junctions of conductive components and insulating materials inside the device, which can lead to high-frequency electromagnetic field leakage and signal interference, further reducing detection accuracy. Finally, because the mechanical structure design of the leakage current detection device does not fully consider the thermal expansion effect under high-temperature environments, the connectors may loosen during use, and the sensor may also shift, all of which affect the stability and reliability of the device.

[0027] Reference Figure 1-4 A high-frequency electrosurgical leakage current detection device, comprising:

[0028] The outer surface of the conductive connector 1 is coated with an anti-oxidation coating to prevent oxidation reaction under the action of high frequency current, ensuring stability and reliability for long-term use. The anti-oxidation coating is a nickel-based alloy material with excellent corrosion resistance and conductivity, which further enhances the stability and service life of the conductive connector 1.

[0029] The conductive connector 1 is used to reliably connect the high-frequency electrosurgical unit and the high-frequency current transformer 2 to prevent inaccurate leakage signal capture due to improper installation position. The high-frequency current transformer 2 is used to detect the leakage current of the high-frequency electrosurgical unit. Its installation position is precisely matched with the conductive connector 1 to ensure accurate capture of leakage signal. The end of the conductive connector 1 is provided with a threaded connection part 6, which is used to tightly fix the high-frequency electrosurgical unit and the high-frequency current transformer 2 to ensure that it is not easy to loosen during installation, thereby improving the accuracy of leakage current signal capture.

[0030] The insulating support frame 3 is used to fix the high-frequency current transformer 2 and is made of a material with a low coefficient of thermal expansion to avoid the loosening of the connectors due to thermal expansion under high temperature environment. The insulating support frame 3 has multiple heat dissipation channels 7 inside, which accelerate the dissipation of heat through natural convection or forced convection to avoid material deformation caused by long-term operation in high temperature environment. The outer surface of the insulating support frame 3 is covered with heat sink 8, which further increases the surface area, enhances the heat conduction effect, and improves the overall heat dissipation capacity.

[0031] The shielding shell 4 is used to enclose the high-frequency current transformer 2 and the insulating support frame 3 to prevent high-frequency electromagnetic field leakage and signal interference caused by tiny gaps at the joints between the conductive components and the insulating materials inside the device.

[0032] The elastic fastener 5 is installed between the insulating support frame 3 and the shielding shell 4 to ensure that the high-frequency current transformer 2 can be stably fixed in a high-temperature environment and to prevent sensor displacement. The shielding shell 4 has a shielding layer inside, which is composed of multiple layers of conductive metal materials. This shielding layer effectively blocks the interference of external electromagnetic fields and reduces the leakage of internal electromagnetic signals. The conductive connector 1 is tightly connected to the high-frequency current transformer 2 to ensure effective transmission of high-frequency current. The insulating support frame 3 is firmly connected to the shielding shell 4 through the elastic fastener 5. The overall structure is stable and suitable for high-temperature environments.

[0033] The specific working principle of this utility model is as follows:

[0034] In actual operation, when this device is used, the conductive connector 1 is first reliably connected to the high-frequency electrosurgical unit. This connection ensures that the leakage current generated by the high-frequency electrosurgical unit during operation can be efficiently transmitted to the high-frequency current transformer 2. Subsequently, the high-frequency current transformer 2 starts working, its precise installation position perfectly matching the conductive connector 1, ensuring accurate capture of the leakage current signal from the high-frequency electrosurgical unit. The leakage current detected by the high-frequency current transformer 2 is transmitted to the subsequent detection stage through the fixing effect of the insulating support frame 3. The insulating support frame 3 is made of a material with a low coefficient of thermal expansion. This design effectively avoids the loosening of the connector due to thermal expansion under the high temperature environment generated by the high-frequency electrosurgical unit during long-term operation, thereby ensuring the stability and reliability of the device.

[0035] Meanwhile, the shielding shell 4 completely encloses the high-frequency current transformer 2 and the insulating support frame 3, providing dual protection. It not only prevents high-frequency electromagnetic field leakage caused by tiny gaps at the junction of the conductive components and insulating materials inside the device, but also avoids interference from external electromagnetic fields on the internal detection signal, thereby improving the accuracy and stability of the detection. The elastic fixing element 5 provides additional support between the insulating support frame 3 and the shielding shell 4, further ensuring that the high-frequency current transformer 2 remains stable and immovable, even under thermal expansion and contraction, ensuring the consistency and reliability of the detection results. The synergistic effect of this series of components enables the high-frequency electric current leakage detection device to perform leakage current detection stably and accurately under various complex conditions.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
