Abstract
In modern surgery, microwave surgical energy devices are used for hemostasis and anastomosis. However, elongated heating region called backward heating distributes around the feeding line, and potentially causes undesirable heating to non-targeted, normal tissue. In order to suppress the backward heating, we considered use of a sleeve with microwave device. Large sleeve inner diameter is required to use the sleeve effectively. However, small sleeve inner diameter is preferable for use in surgery. In this study, numerical analyses were performed to investigate the optimum sleeve inner diameter. The results indicated over 4 mm inner diameter could suppress the backward heating.
期刊介绍:
An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include:
- Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.)
- Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.)
- Electromagnetic theory
- Microwave and millimeter-wave devices, circuits, and modules
- THz devices, circuits and modules
- Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials)
- Integrated circuits (memory, logic, analog, RF, sensor)
- Power devices and circuits
- Micro- or nano-electromechanical systems
- Circuits and modules for storage
- Superconducting electronics
- Energy harvesting devices, circuits and modules
- Circuits and modules for electronic displays
- Circuits and modules for electronic instrumentation
- Devices, circuits and modules for IoT and biomedical applications
