Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings, but the present invention is not limited thereto.

Referring to fig. 1, the current argon-helium knife super-cooled surgical instrument comprises a right-angle super-cooled surgical instrument and a main-angle super-cooled surgical instrument. The two types of super-cold surgical instruments are composed of a cutter rod part A and a cutter handle part B, the diameter of the right-angle super-cold surgical instrument cutter rod part A is 2.4mm, the length of the right-angle super-cold surgical instrument cutter rod part A is 15cm, and the diameter of the main-angle super-cold surgical instrument is 1.7mm, and the length of the main-angle super-cold surgical instrument cutter rod part A is 15 cm. When the argon-helium scalpel is used for operation, the cutter bar part A is punctured into the skin of the thoracic cavity, and the cutter bar part A is fixed on the surface of the skin by the utility model.

Referring to fig. 4, a sterile adhesive type fixing device of an argon-helium knife super-cooled surgical instrument. The method comprises the following steps: the bottom hydrogel 2, the fixed base 1 and the fixed rubber plug 3 shaped like a Chinese character 'mi' are sterilized for use.
