A protective casing for a treatment machine

Abstract

The invention discloses a protective shell of a therapeutic instrument. The protective shell comprises an on-off key and a protective shell body with a through hole. A cylindrical sealed cavity is formed in the protective shell body, the inner wall of the sealed cavity is provided with an annular groove, a sealing gasket is fixed into the annular groove, and the on-off key penetrates through the through hole and is arranged in the sealed cavity. The bottom of the on-off key is connected with a movable rod with one end penetrating through the bottom of the sealed cavity, and a circular base plate is fixed to the movable rod. The outer circumference of the circular base plate is in contact with the sealing gasket consistently. The sealing gasket can deform in the annular groove so that the circular base plate can be in contact with the sealing gasket in the sealed cavity consistently, complete sealing between the outside and the inside of the protective shell body is ensured, outside moisture or dust is completely prevented from entering the therapeutic instrument through the on-off key, the control function and the flexibility of switching-on and switching-off of the therapeutic instrument before and after the therapeutic instrument is used are ensured, the using efficiency of the therapeutic instrument is improved, and meanwhile the medical accident occurrence rate caused by the failure of switching-on and switching-off is reduced.

Description

technical field [0001] The invention relates to a therapeutic apparatus, in particular to a protective shell of a therapeutic apparatus. Background technique [0002] During the treatment of the ion therapy machine, according to different lesions, the treatment needles with different diameters are selected to contact or insert into the human lesions, and the gas molecules are separated by using the extremely high electric field strength formed in the tiny air gap between the contacts and the tissue to generate plasma. body flame. When a strong output is selected, a high temperature of about 3000°C is generated instantaneously, making the diseased tissue gasify and disappear. At the same time, because there is a thin coagulation layer under the gasification layer, it can prevent bleeding, protect the surface tissue, and make the wound heal quickly. When the weak output is selected, the lesion tissue can be coagulated or charred and necrotic, so as to achieve the purpose of ...

AI Technical Summary

Problems solved by technology

[0003] At present, ion therapy devices on the market have a wide range of functions, but during medical treatment, the switch of the ion therapy device is exposed to the outside, and dust or water vapor from the outside can easily enter the electronic circuit inside the therapy device. At the time of innovation, the switch button directly failed, so that the treatment machine could not be stopped immediately after the operation was completed, and it interfered with the judgment of the treatment personnel, resulting in medical accidents
