Low-temperature-surgery assistant diagnosis-treatment system based on non-destructive reconstruction technology of three-dimensional temperature field of human body

Abstract

The invention relates to the technical field of medical equipment, and discloses a low-temperature-surgery assistant diagnosis-treatment system based on a non-destructive reconstruction technology ofthe three-dimensional temperature field of the human body. The system includes a software part and a hardware part, wherein the software part mainly includes a human-biological-tissue three-dimensional temperature field database which is obtained through finite element simulating calculation, the database is stored in a host, and the hardware part mainly includes a cold knife temperature automatic-collecting system during a low-temperature surgery, human biological tissue, a data collecting instrument, the host, a display, a thermistor, a pressure sensor and signal input ports; and the cold knife temperature automatic-collecting system includes a cold knife head and a liquid supply pipeline, the thermistor includes temperature signal lines, and pressure signal lines are arranged in the pressure sensor; and the signal input ports include a cold knife temperature data input port, a cold knife dwell time data input port and a controlled manual input port. During implementation of cryosurgery, comprehensive clinical judgment and real-time adjustment of a surgical plan of doctors can be assisted effectively through the system, and the efficiency of cryosurgery is improved effectively.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a low-temperature surgery auxiliary diagnosis and treatment system based on the non-destructive reconstruction technology of the three-dimensional temperature field of the human body. Background technique [0002] Hypothermia surgery, as a kind of physical therapy for tumor treatment, has obvious advantages compared with ordinary surgery, such as low operation cost, good hemostasis effect, light pain, low postoperative infection rate, convenient and flexible operation, etc. However, hypothermic surgery has not become a routine therapy for tumor treatment at this stage. The main reason is that the current clinical implementation process is summarized, and there is a lack of accurate detection methods for tissue temperature distribution and cell crystallization range, resulting in the precise control of freezing cooling and thawing rewarming. It is very difficult. On the ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a low-temperature surgical auxiliary diagnosis and treatment system based on the non-destructive reconstruction technology of the three-dimensional temperature field of the human body, which has the advantages of high efficiency, reliability, low cost, and universality, and solves the current clinical implementation process summary, which lacks precision. The temperature distribution of the tissue and the detection method of the cell crystallization range make it very difficult to precisely control the cooling and rewarming of the freezing process. All diseased tissues are killed, which makes the recurrence rate of traditional hypothermic surgery relatively high
