A medical laser thermotherapy target head based on graphite-based composite heat-conducting material

Abstract

The invention discloses a medical laser thermotherapy target head based on a graphite-based composite heat-conducting material; it includes a protective jacket, an inner heat-insulating layer, a heat-conducting belt and an outer heat-insulating layer; The side of the connector and the center of the rear end of the connector are respectively provided with openings, and the two openings are connected through a channel, and the opening in the center of the rear end of the optical fiber connector extends into the side opening of the end; the inner insulation layer wraps On the outer periphery of the optical fiber at the back end of the connector, there are multiple layers of conductive tape, and the multiple layers are arranged at intervals on the outer periphery of the inner heat insulating layer, and the conductive tape of each layer is arranged at intervals; the outer heat insulating layer is wrapped around the outer periphery of the conductive tape; the conductive tape is composed of multiple long arcs It is composed of flakes; the conductive tape is made of graphite-based thermally conductive material; it solves the problem of burning damage caused by thermal deposition during the use of the target and the flexibility of the target, which is conducive to improving the power of the medical laser hyperthermia target and reducing the target. head quality and reduce target head quality.

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
