Embodiment Construction

[0030] In order to provide a more rigorous and scientific implementation plan for preventing thermal injury complications and improving the success rate of radiofrequency ablation treatment, the embodiment of the present invention provides a medical temperature-sensitive detection method and device. The following describes the preferred embodiment of the present invention in conjunction with the accompanying drawings Be explained.

[0031] refer to figure 1 As shown, the shaded area on the left is the tumor on the thyroid gland, and the black area next to the tumor is the recurrent laryngeal nerve near the thyroid gland. During radiofrequency ablation, the internal tissues of the human body can be observed in real time through ultrasound guidance. At this time, radiofrequency puncture needles are used Insert the tumor tissue, and the radiofrequency puncture needle can make the temperature in the tumor tissue exceed 60°C, causing coagulation necrosis. When the tumor tissue is h...

Abstract

The invention discloses a medical thermosensitive detecting method and device which is used for solving the problem about heat injury to healthy tissues in the tumor oblation operation. The medical thermosensitive detecting device comprises a thermosensitive puncture probe (1), a converter (3) and a server (5). The thermosensitive puncture probe (1) is used for detecting temperature of a to-be-detected tissue contacting with the thermosensitive puncture probe when a radio frequency puncture needle transmits radio frequency signals and generating corresponding temperature signals after detecting the temperature of the tissue to be detected, the converter (3) is connected with the thermosensitive puncture probe (1) through a first connecting line (2) and used for converting the temperature signals into thermoelectromotive force signals, and the server (5) is connected with the converter (3) through a second connecting line (4) and used for receiving the thermoelectromotive force signals via the second connecting line, calculating the temperature via analog-digital conversion of the thermoelectromotive force signals and displaying the temperature. The medical thermosensitive detecting device is used with the radio frequency puncture needle, puncture times can be reduced, pain of patient is alleviated, requirements for experience of operators are lowered, and heat injury to the healthy tissues in the tumor oblation operation is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of tumor ablation therapy, in particular to a medical temperature-sensitive detection method and device. Background technique [0002] Radiofrequency ablation therapy is a minimally invasive and non-surgical medical technology emerging in the past ten years. At present, this technology is mainly aimed at the treatment of benign thyroid nodules or recurrent malignant tumors. The principle of this technique will be described in detail below by taking the ablation treatment of thyroid nodules as an example. [0003] Radio frequency refers to radio frequency, and the effect on living organisms is mainly thermal effect. When the frequency of the radiofrequency current is between 200kHz and 1200kHz, it will cause tissue ions to rub against each other with the direction of the current change to generate heat. When the local temperature of the tissue reaches between 45°C and 50°C, the tissue will be dehydrated, th...
