BACKGROUND: Thermofusion device utilized in interventional surgery easily leads to sealing carbonization or blood leaking due to overheat.OBJECTIVE: To discuss the application of PTC polymer in radio-frequency thermofusion device.METHODS: For medical application of PTC Polymer in radio-frequency endo-surgical devices, polymer selecting rules were set and the PTC was prepared; the function of prepared device was tested. RESULTS AND CONCLUSION: The functional testing showed that the device meet the requirement on RF thermo-fusion and tissue cut. With the application of the key material into thermal fusion devices, it yielded fast and safe dissection and fusion of tissues and arteries of varies diameter; no fume, no carbonization and no conglutination between device surface and coagulation tissues are found. Because of minimum heat conduction, the device can protect effectively the surrounding organs as thin as possible. By combining such device with conventional electrosurgical station, minimum output and auto-stopping operation can be realized.
