Thermal infrared image system and method for analyzing surface temperature influence factors of free flaps

Abstract

The invention relates to a thermal infrared image system and a method for analyzing surface temperature influence factors of free flaps. The method includes by a thermal infrared imager, acquiring an actually-measured surface temperature of a free flap of an organism, further acquiring a core temperature of the organism and a room temperature of a located environment, respectively performing thermal conduction and thermal convection operations on the core temperature and the environmental room temperature to generate a predicted surface temperature, judging whether or not the surface temperature influence factors of the free flap is changed according to whether or not the predicted surface temperature is close to the actually-measured surface temperature, and taking a judgment result as the basis for compensation and correction to improve accuracy of acquiring a surface temperature of the free flap as a reference index by the thermal infrared imager.

Description

technical field [0001] The invention relates to a method and system for monitoring the surface temperature of a free skin flap, especially to a method for obtaining the surface temperature of a free skin flap by using an infrared thermal image, and analyzing various factors affecting the surface temperature, as a correlation basis for correction and compensation. technology. Background technique [0002] "Free flap surgery" is often used in reconstructive surgery, such as facial reconstruction after surgery for oral cancer patients. The so-called "free flap surgery" is to remove a certain part of the patient's body tissue together with its blood vessels, and then transplant the removed tissue to the wound that lacks tissue coverage on the patient's body. Therefore, it is necessary to cooperate with medical-grade microscopes for precise blood vessel suturing. Due to the fine and dense blood vessels, close observation must be made after suturing to confirm whether there is v...

Problems solved by technology

However, its surface temperature is only obtained from a single point on the free flap, and the data obtained are not comprehensive and objective enough to affect the accuracy of its judgment. In addition to being affected by embolism, the surface temperature of the free flap is also affected by other factors. The influence of other factors cannot be fully considered, which will affect the accuracy of free flap surface temperature interpretation

[0006] From the above, it can be seen that the acquisition of the surface temperature of the existing free flap has not been fully extended, and the objectivity of obtaining the surface temperature as an indicator is also insufficient, and further review is needed to seek a feasible solution
