Insulating and adiabatic gamma knife stereotactic positioning frame head nail

Abstract

The invention discloses an insulating and adiabatic gamma knife stereotactic positioning frame head nail. The head nail comprises a titanium tail, an insulating and adiabatic body, and a titanium tip. The insulating and adiabatic body is of a cross structure composed of a disk and a central axis. The insulating and adiabatic body is clamped onto the lower end of the titanium tail and the top end of the titanium tip. The central axis of the insulating and adiabatic body extends into the titanium tail and the titanium tip. The head nail has the characteristics of simple structure, low cost, and good heat insulation effect. An interference fit structure is adopted. The product precision is high. A magnetic wire ring does not form eddy current during treatment. Heat or high temperature is not easy to produce. The problem of heat transfer is solved. The precision of products is improved. Effective guarantee is provided for measurement. Thus, the effect of radiotherapy is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an insulating and heat-insulating gamma knife stereotaxic frame head nail. Background technique [0002] Gamma Knife Stereotaxic Frame Head Nail is a new type of stereotaxic radiotherapy technology for tumor treatment. The parts that are in contact with the human head are usually made of integral titanium alloy at home and abroad; the following two problems may occur during clinical use; [0003] (1) Due to the long treatment process, the stereotaxic frame head nails will conduct heat through the electromagnetic coil, and the heat will be transferred to the human head, which will burn the human head; [0004] (2) The head nails of the stereotaxic frame and the headgear are connected by threads, and the headgear is made of aluminum alloy. In long-term use, the titanium alloy head nails conduct heat, and the threads may burn to death, resulting in the inability to remove the titan...

AI Technical Summary

Problems solved by technology

In long-term use, the titanium alloy head nails conduct heat, and the threads may burn to death, resulting in the inability to remove the titanium alloy head nails and the headgear, and ultimately the headgear of the treatment equipment cannot be separated from the human body

The headgear can only be cut as a whole by cutting, which will damage the headgear.
