Problems solved by technology

There are also some manufacturers who use simple loss tools for testing. The operation is complicated and requires high personnel requirements. The test results of different personnel are different, resulting in unstable test results, no traceability, and excessive loss, requiring irregular maintenance.

Embodiment 1

[0035] Such as figure 1 As shown, the airtightness testing device of the ENT plasma electrode in the embodiment of the present invention includes a titration pipeline sealing device 1 , a suction pipeline sealing device 2 , an electrode head sealing device 3 and a gas pipeline 4 . The titration pipeline sealing device 1 is set to the titration pipeline 6 of the ENT plasma electrode 5 to be tested (such as figure 2 shown) fixed seal, the suction line sealing device 2 is set to the suction line 7 of the ENT plasma electrode 5 to be tested (such as figure 2 shown) fixed seal, the electrode head sealing device 3 is set to the electrode head 8 of the ENT plasma electrode 5 to be tested (such as figure 2 shown) is fixedly sealed; the first branch of the gas pipeline 4 is fixedly connected to the sealing device 1 of the titration pipeline, and the second branch of the gas pipeline 4 is fixedly connected to the sealing device 2 of the suction pipeline.

[0036] The titration line...

Embodiment 2

[0045] In the embodiment of the present invention, the sealing mechanism of the electrode head sealing device 3 is an extrusion type sealing structure, such as image 3 As shown, the electrode head 8 of the otolaryngology plasma electrode 5 to be tested is passed through the third fixing module, and after the sealing ring 9 is put on, the electrode head 8 is extended into the sealing mechanism, and the lever of the third locking mechanism The rotating operation is performed to make the sealing mechanism squeeze the sealing ring, and then the electrode head 8 of the plasma electrode 5 to be tested is sealed, which is convenient and quick.

[0046] The material of the sealing ring 9 can be silica gel, rubber, fluorine rubber or fluorine rubber, etc. In this embodiment, silica gel is selected.

[0047] Others are the same as in Example 1.

Embodiment 3

[0049] In the embodiment of the present invention, the electrode head sealing device 3 includes a third fixing device with a spring inside, and a sealing ring 9 is set in the spring in the third fixing device. The electrode head 8 passes through the spring and the sealing ring 9 in the third fixing device, and the sealing ring 9 is pressed by the compression spring to realize sealing.

[0050] The material of the sealing ring 9 can be silica gel, rubber, fluorine rubber or fluorine rubber, etc. In this embodiment, rubber is selected.

[0051] Others are the same as in Example 1.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for testing the air tightness of a plasma electrode in the Department of Otorhinolaryngology. Background technique [0002] Human beings' understanding of plasma began with the study of gas discharge in the 1830s, and the concept of plasma was established in the early 20th century, that is, a system with macroscopic space-time slowness composed of a large number of interacting charged particles; plasma is charged according to The relative temperature of particles can be divided into high-temperature plasma and low-temperature plasma. [0003] Plasma radiofrequency ablation was first applied in 1995. In 1995, the first company was successfully registered and used in the US FDA. It has been widely used in the medical industry in 1997. The radiofrequency ablation treatment technology in my country started almost at the same time as the international upsurge. The int...
