Tattooing needle without resilience force and tattooing device by using needle

Abstract

The invention discloses a tattooing needle without a resilience force and a tattooing device by using the needle. The tattooing needle without a resilience force comprises a syringe, a needle body, a needle base, a first connection rod and a first connection block, wherein the first connection block is driven by an external force to directly perform reciprocating motion; and the first connection block drives the needle body via the first connection rod and the needle base to perform reciprocating linear motion. The tattooing needle without a resilience force has the beneficial effects that the needle does not use any spring, any rubber band or any rubber ring to provide a resilience force, the external force is directly used for driving, and quick withdrawing can be realized; and the problems that resilience disappears due to long-time use of the resilience force and the needle can not be withdrawn are solved. The invention also provides a tattooing device, which comprises a motor, a handle shell, a second connection rod and the above mentioned tattooing needle. When the motor pushes the needle body, resilience force work does not need to be overcome, current and power of the motor are maintained to be stable, and the service life of the motor is greatly prolonged.

Description

technical field [0001] The invention relates to a medical device, in particular to a non-resilience tattooing needle and a tattooing device using the needle. Background technique [0002] In today's society, the beauty industry is developing more and more rapidly. People will choose tattoos, embroidered eyebrows, embroidered lips and other methods to beautify themselves for the sake of beauty. In these processes, a once-used tattooing needle and a tattooing device using the needle are required. [0003] Usually, for the convenience of tattooing, the tattooing devices in the prior art are all configured so that the needle body can automatically reciprocate back and forth. The usual needles use springs, rubber bands or rubber rings as the resilience, so that the needle itself has resilience. When in use, the drive of the motor is used to push the needle body forward and out. During the process of electric drive, the spring is compressed or the rubber band and rubber ring are ...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many deficiencies in this method of using elastic force as the retracting force

First of all, the retraction of the needle depends on the elastic force, but the elastic force requires a certain amount of deformation to achieve work, and its speed is from fast to slow, there will be a certain delay, and rapid retraction cannot be achieved; secondly, the spring, rubber After a long time of use, the tendons and rubber rings will lose their elasticity, making the needle unable to retract; finally, when the motor pushes the needle, it needs to overcome the elastic force to do work, and the elastic force will become larger and larger, so that the current and power of the motor It will become bigger instantly, and the motor is particularly easy to be damaged during the long-term current and power sudden rise and fall, which shortens the life span
