Abstract

The invention discloses a bionic anti-sticking high-frequency electrotome bit, and belongs to the technical field of energy-carrying minimally invasive medical instruments. The bionic anti-sticking high-frequency electrotome bit takes a plant leaf with anti-sticking and desorption functions as a prototype, a bionic surface form with round grooves and strip-shaped grooves distributed in a compound mode is machined in the surface of a high-frequency electric-conduction blade by simulating the surface form of the plant leaf, the round grooves and the strip-shaped grooves are distributed in the length direction of the blade alternatively, and the interval between the two types of forms is equal to the radius of the circle; the round grooves and the strip-shaped grooves are respectively distributed in the width direction of the blade at equal intervals, and the center distance is 460-700 micrometers; the diameter of each round groove is equal to the width of each strip-shaped groove and is 180-300 micrometers; the length of each strip-shaped groove is 800-1400 micrometers; the depth of each round groove and the depth of each strip-shaped groove are the same and are both 60-100 micrometers. The bionic anti-sticking high-frequency electrotome bit effectively reduces the carbonization and sticking phenomena of the tissue when the electrotome works at a high temperature, and is favorable for heat radiation, and the minimum sticking quality is reduced by about 39% compared with a smooth electrotome bit.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive medical devices, and relates to an anti-adhesive high-frequency electric knife head with a bionic surface shape. Background technique [0002] Minimally invasive surgery has the characteristics of small trauma, light pain, and quick recovery. High-frequency electrosurgery is the most common energy-carrying minimally invasive surgery. It heats the tissue when the high-frequency high-voltage current generated by the tip of the knife comes into contact with the body. Reach the protein denaturation temperature, realize the separation and coagulation of body tissue, so as to achieve the purpose of cutting and hemostasis. Due to the sticky, slippery and soft characteristics of living soft tissues or organs, it is easy to cause tissue burns and burns during surgical operations, and stick to the surface of the instrument, causing tissue tears and burns. According to statistics, more than 80% o...
