Antifriction effect of 316L stainless steel textured surface with superhydrophilic properties in brain tissue insertion
To reduce the tissue damage caused by the cannula electrodes during the operation of deep brain stimulation, laser matching micro texture on the surface of the electrodes was proposed to reduce the friction force. Different grooves and pit arrays were fabricated on the 316L stainless steel surface u...

| description | To reduce the tissue damage caused by the cannula electrodes during the operation of deep brain stimulation, laser matching micro texture on the surface of the electrodes was proposed to reduce the friction force. Different grooves and pit arrays were fabricated on the 316L stainless steel surface using an ultra-violet nanosecond laser. The wettability of textured surfaces with different morphologies was measured by distilled water and artificial cerebrospinal fluid. Insertion experiments were carried out on porcine brains using textured steel needles. The results showed that textured steel needles have an obvious antifriction effect under the condition of the lubricant. The elliptical pit texture has the best effect of reducing friction, and the friction force can be reduced by 37.6% on average. |
