Abstract
The invention discloses a surface self-lubricating anti-adhesive structure of an energy carrier minimally invasive operation knife. Micro-nano structures are machined on the surface of the energy carrier minimally invasive operation knife and are regular or irregular micro-structures which are machined on the surface of the operation knife in a micro scale, or a nano scale or a micro-nano scale. The micro-nano structures are micro grooves, micro arrays, micro pore channels and others. The surface acting force of gaps of the micro-nano structures is used for drawing biocompatible liquid to lubricate the surface of the operation knife, and the biocompatible liquid can be used for protecting the soft tissue from making contact with the surface of the operation knife through isolation, so that the liquid makes contact with the soft tissue, the temperature of the surface of the operation knife is effectively lowered, then the situation that the soft tissue adheres to the surface of the operation knife is reduced, the situation that the tissue is damaged due to adhering is reduced, and the safety of an energy carrier minimally invasive operation is improved.
Description
Technical field
The present invention relates to a kind of antiseized structure of load energy Minimally Invasive Surgery cutter surface self-lubricating, more specifically, refer to one
Plant and carrying and can process micro-nano structure on Minimally Invasive Surgery cutter, act on gravitational attraction liquid moistening surgical knife tool using micro-nano structure surface
