Automatic reset type ultrasonic scalpel capable of reducing resonant frequency

Abstract

The invention discloses an automatic reset type ultrasonic scalpel capable of reducing resonant frequency, and belongs to the technical field of ultrasonic scalps. The automatic reset type ultrasonic scalpel comprises an ultrasonic scalpel body and an outer pipe, wherein the outer pipe is fixedly connected to the right side surface of the ultrasonic scalpel body, an adjusting mechanism is arranged on the outer surface of the outer pipe, the adjusting mechanism is fixedly connected to the inner part of the outer pipe, and a shock absorption mechanism is arranged on the outer side of the outer pipe. According to the automatic reset type ultrasonic scalpel, the shock absorption mechanism is arranged, two silica gel blocks can extrude a cutter bar, the resonance amplitude and frequency of the cutter bar are reduced through buffering performance of the shock absorption mechanism, the cutter bar is effectively protected, the adjusting mechanism is arranged, a rotating screwing block drives transmission wheels to rotate, and the two transmission wheels can rotate at the same time under the action of a belt; and at the moment, two clamping plates get close to each other, then two extrusion blocks can get close to each other, the cutter bar can be extruded, the resonance amplitude and frequency of the cutter bar are adjusted and controlled by changing the extrusion force on the cutter bar, and the problem of the cutter bar in the using process is solved.

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
