Syringe needles for cosmetic surgery

Abstract

The invention discloses a syringe needle for cosmetic surgery, which comprises a connecting head which is sleeved with the front end of a needle cylinder and a puncture needle which is arranged on theconnecting head; the head end of the puncture needle is sleeved with a rubber sleeve; a through hole which slidably sleeves on the puncture needle is formed in the rubber sleeve; an elastic telescopic structure is arranged between the rubber sleeve and the connecting head, and the elastic telescopic structure comprises a rod body and a cylinder body which are slidably connected in a sleeve mode;one end of the rod body, in the cylinder body, and is connected with the inner wall of the cylinder body through a spring. When the needle is not used, the elastic telescopic structure pushes the rubber sleeve to cover the needle tip of the puncture needle and protect the needle tip, the potential safety hazard is avoided, and meanwhile, the needle tip can be prevented from being polluted; duringinjection, the puncture needle is used for puncturing, the skin can reversely push the rubber sleeve to facilitate exposing the needle tip for puncture, a guide structure is formed between the rod body and the cylinder body during the retracting process of the rubber sleeve, and the puncture efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a syringe needle for cosmetic surgery.
