Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a water-light injection handle and a water-light injection instrument. Background Art

[0002] The water-injection device is an instrument that can perform injection-type skin care treatments. During injection, a matching injection handle is required. While using negative pressure to lift the skin, the beauty injection is delivered to the dermis of the skin in the target area, thereby moisturizing, improving skin tone and nourishing the skin.

[0003] The invention patent with application number CN202210487360.3 discloses an injection device capable of injecting liquid, wherein a negative pressure pipeline enters the interior of the shell from the rear end of the shell, extends along the inner wall of the shell, and is finally connected to the negative pressure joint at the front end of the shell; however, since the pipeline is arranged between the screw seat and the inner wall of the shell, the pipeline needs to occupy a larger internal space of the shell, and since the pipeline extends for a long time, a special fixing structure for fixing the pipeline needs to be provided when necessary to prevent it from moving and affecting the operation of other components.

[0004] The invention patent with application number CN202211202638.4 discloses an anti-backflow structure of an electronic syringe booster device. After the negative pressure pipeline is connected from the main unit of the water-light injection instrument, it is directly connected to the water-light needle at the front end of the handle, and the pipeline is exposed on the outside of the shell; however, since the pipeline is exposed to the outside, when the handle is waved to adjust the injection angle and move the injection position, the suspended negative pressure tube may fall off by itself under the action of gravity. At the same time, the suspended negative pressure tube will hinder the movement of the medical staff's arms, and when the arm movement collides with the negative pressure tube, it will also cause the negative pressure tube to fall off.
