Medical laser thermal therapy target head based on graphite-based composite thermal conductive material

Abstract

The invention discloses a medical laser thermal therapy target head based on a graphite-based composite thermal conductive material. The medical laser thermal therapy target head comprises a protective jacket, an inner heat insulating layer, heat conductive bands and an outer heat insulating layer. The front end of the protective jacket is provided with an end head, and the back end is provided with a connecting body. A side part of the connecting body and the center of the back end part of the connecting body are respectively provided with openings which communicate through a channel. A fiberextends into the opening of the center of the back end part of the connecting body and reaches the opening of the side part of the end head. The inner heat insulating layer coats the outer peripheryof the fiber at the back end of the connecting body. The multiple layers of heat conductive bands are spaced apart at the outer periphery of the heat insulating layer, and each layer of heat conductive bands is spaced. The outer heat insulating layer coats the outer periphery of the heat conductive bands which are formed by multiple long curved pieces. The heat conductive bands are made of graphite-based heat-conducting materials. The problem of burning due to thermal deposition and the flexibility of the target head during the use of the target head are solved, the improvement of the power ofthe medical laser thermal therapy target head is facilitated, and the mass of the target head is reduced.

Description

technical field [0001] The invention relates to a laser thermotherapy target head, in particular to a medical laser thermotherapy target head based on a graphite-based composite heat-conducting material, belonging to the field of medical thermotherapy instruments. Background technique [0002] Hyperthermia uses an external heat source to heat tumor tissue to kill cancer cells without damaging normal tissue cells. It is used in precision tumor hyperthermia as a supplement to surgery, chemotherapy, radiotherapy and biological therapy. Due to the characteristics of high brightness, directivity and monochromaticity of the laser, it becomes a good heat source for hyperthermia. Using a fiber laser, the optical fiber equipped with a laser head is inserted into the tumor tissue to be treated, and the laser is guided to irradiate the corresponding tissue. The heat achieves a precise therapeutic effect. Existing laser therapy heads are often water-cooled, such as using a rigid all-me...

AI Technical Summary

Problems solved by technology

Existing laser therapy heads are often water-cooled, such as using a rigid all-metal water-cooled target head. The metal water-cooled target head requires a fluid delivery mechanism, so the target head is bulky, which is not conducive to reducing the wound area; and the water-cooled micro The channel processing is difficult and the thermal conductivity is limited, which leads to the easy burning of the optical fiber head and the adhesion between the tissue; at the same time, the rigid all-metal water-cooled target head has a rigid structure, and the flexibility of the target head is poor, and it is difficult to avoid the large blood vessels of the human body during use. or vital organs, the risk of treatment is high
