Abstract

An intelligent tissue separating surgical instrument capable of detecting electrical bioimpedance comprises a detecting electrode, a connecting wire, an impedance analysis instrument and a pedal. The detecting electrode and the pedal are connected with the impedance analysis instrument through the connecting wire. The detecting electrode comprises two layers of glass fiber plates. Two pieces of copper foil for conducting current are electroplated between the two layers of glass fiber plates. The tip end of the detecting electrode is an inclined surface. Two stainless steel hemispheroids are welded to the inclined surface and electrically connected with the two pieces of copper foil respectively. The other end of the detecting electrode is connected with the impedance analysis instrument through an electrical connector and a wire. The intelligent tissue separating surgical instrument has the advantages of being free of incision, low in price, safe, free of toxin and damage, intelligent in operation, rich in information and the like.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to an intelligent tissue separation surgical instrument capable of detecting bioelectrical impedance, belonging to the technical field of medical instruments. Background technique [0002] Bioelectrical impedance detection technology is a detection technology that uses the electrical impedance characteristics of biological tissues and its changing rules to extract biomedical information related to human physiological and pathological conditions. This detection technology usually needs to apply a weak alternating current or voltage signal to the detected tissue by means of at least two electrodes, so as to calculate the complex impedance according to the magnitude and phase of the applied current or voltage, and finally obtain relevant physiological and pathological parameters according to different application goals. information. Bioelectrical impedance detection technology has the advantag...
