A self-resetting ultrasonic scalpel capable of reducing resonance frequency

Abstract

The invention discloses an automatic reset type ultrasonic knife capable of reducing resonance frequency, which belongs to the technical field of ultrasonic knife and comprises an ultrasonic knife body and an outer tube. The right side of the ultrasonic knife body is fixedly connected with an outer tube, and the outer tube An adjustment mechanism is arranged on the outer surface, and the adjustment mechanism is fixedly connected in the outer tube, and a shock absorbing mechanism is arranged on the outer side of the outer tube. In the present invention, by setting the shock absorbing mechanism, the two silica gel blocks can squeeze the cutter rod, and use its own buffer performance to reduce the resonance amplitude and frequency of the cutter rod, effectively protecting the cutter rod. By setting the adjustment mechanism, the rotating The screwing block drives the transmission wheel to rotate, and the two transmission wheels can rotate simultaneously under the action of the belt. At this time, the two splints are close to each other, so that the two extrusion blocks can be close to each other, so that the tool bar can be squeezed. By changing The extrusion force on the cutter rod regulates the resonance amplitude and frequency of the cutter rod to avoid problems during the use of the cutter rod.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic knife, in particular to an automatic reset type ultrasonic knife capable of reducing resonance frequency. Background technique [0002] Ultrasonic scalpel is a beauty technology developed on the basis of ultrasound, which can release a high-intensity energy-concentrated ultrasound, and use the physical characteristics of ultrasound in biological tissues such as directionality, penetration, and focusability to penetrate the external energy ultrasound into normal skin. The tissue is precisely focused on the beauty treatment area in the body, and a thermal coagulation point of 65-70°C is generated instantly within 0.5s, so that the tissue cells in the target area immediately produce a protein coagulation reaction, and a pulling force is generated around the coagulation point to immediately show tightening and lifting Effect. The effect of ultrasonic scalpel usually lasts for 2 to 3 years. The be...

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the existing ultrasonic knife will produce a certain resonance when it is working, and when it is in contact with bone tissue during the cutting process, due to the greater resistance received, the resonance frequency generated at this time is stronger, not only The operation effect is poor, and it is easy to damage the knife rod, which is not conducive to the long-term treatment of hard tissues by the ultrasonic scalpel. After the work is completed, it is necessary to wait for the blade to cool down before storing it, or wait until it has cooled to a certain temperature before starting work. In order to avoid damage to the blade, it will take a long time to waste people's time. Placed on the desktop, this will lead to unstable placement. At the same time, the ultrasonic knife is prone to fall, and the knife rod is easy to contact with the desktop and be polluted. A self-resetting ultrasonic that can reduce the resonance frequency is proposed. Knife
