Surface self-lubricating anti-adhesive structure of energy carrier minimally invasive operation knife

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 [0001] The invention relates to a self-lubricating and anti-adhesive structure on the surface of an energy-carrying minimally invasive surgical tool, more specifically, a micro-nano structure processed on an energy-carrying minimally invasive surgical tool, and the surface force of the micro-nano structure is used to attract liquid Wet the surface of the surgical knife, and achieve lubrication and isolation with a liquid film, so as to prevent soft tissue adhesion during energy-bearing surgery. Background technique [0002] Energy-carrying minimally invasive surgical knives are mainly used for hemostasis, electrocautery separation and cutting of soft tissues. Energy generating tools such as RF power supply output energy signals to energy-carrying surgical tools such as monopolar electric knife, bipolar electrocoagulation forceps, electric pencil, ultrasonic knife, etc., and then generate electric arc, heat energy, mechanical vibration and other energy, and pe...

AI Technical Summary

Problems solved by technology

These methods can achieve a certain degree of anti-adhesion, but the adhesion of adhesive tissue will gradually lose this anti-adhesion ability

Moreover, coating materials such as fluoropolymers and gold are expensive, and excessive temperature will cause fluoropolymers to decompose and release toxic gases
