Maskless Fabrication of PLA‐Based Neural Arrays for CNS Recording and Stimulation

Advanced Materials Interfaces, EarlyView.
Biodegradable neural interfaces enable bidirectional communication with the CNS. Through electrochemical characterization, ageing tests with impedance monitoring, and in vivo validation, we assess the performance of PLA‐based epicortical and spinal implants.

Thermal Management of Bone Drilling Based on Rotating Heat Pipe

Energies, 2021
Bone drilling is a common surgical operation, which often causes an increase in bone temperature. A temperature above 47 °C for 60 s is the critical temperature that can be allowed in bone drilling because of thermal bone osteonecrosis.

Modelling and optimisation of temperature and force behaviour in high-speed bone drilling

Biotechnology & Biotechnological Equipment, 2019
Bone drilling and implantation are important in orthopaedic surgery, dentistry and also fracture treatment. In many cases, due to the rise in temperature during bone drilling (higher than 47 °C) and low conductivity of bone, thermal necrosis occurs ...

Appraising efficiency of OpSite as coolant in drilling of bone

Journal of Orthopaedic Surgery and Research, 2020
Background During drilling of bone, which is common in clinical surgeries, heat generation increases local temperature in the drilling site. Transmission of excessive heat to the surrounding bone tissue can cause thermal osteonecrosis.

Experimental investigation on the effect of drill quality on the performance of bone drilling [PDF]

Biomedical Engineering / Biomedizinische Technik, 2019
Abstract Bone drilling is a well-known process in operative fracture treatment and reconstructive surgery. The cutting ability of the drill is lost when used for multiple times. In this study, the effect of different levels of drill wear on bone temperature, drilling force, torque, delamination around the drilling region and surface ...
