An ultrasonic instrument for use in welding and depositing biological osseous tissue. The instrument is essentially a source of ultrasonic oscillations, comprising an oscillator and a half-wave concentrator which passes gradually into a welding tip not placed in direct contact with both fragments of osseous tissue, which are being joined and which have biological material preliminarily placed therebetween. The welding tip is essentially a blade made from a titanium alloy and having flat faces made bevel at an angle of 90 DEG +/- 45 DEG relative to the longitudinal axis from the free end of the tip to the point at which the latter starts gradually passing into the concentrator.
