Apparatus for rapid reliable electrothermal tissue fusion
Pieces of tissue are fused together by compressing the pieces together at an interface, delivering an impulse of electrical power which is converted into sufficient thermal energy to fuse the pieces together at the interface. The impulse and the fusion occur within a preferable time of 0.5-2.0 secon...

| Zusammenfassung: | Pieces of tissue are fused together by compressing the pieces together at an interface, delivering an impulse of electrical power which is converted into sufficient thermal energy to fuse the pieces together at the interface. The impulse and the fusion occur within a preferable time of 0.5-2.0 seconds but no greater than 4.0 seconds. The temperature of the thermal energy is regulated between 1500C- 2000C. The tissue pieces are compressed to a thickness of 0.05-0.10 mm. Jaws which compress the tissue and transfer the energy have smooth working surfaces with an Ra of 0.15 or less microns to 0.40 microns. |
