Guide needle with smooth needle hole for line carving sawtooth line

Abstract

The invention discloses a guide needle with a smooth needle hole for a line carving sawtooth line, and relates to the technical field of medical plastic instruments, and the key points of the technical scheme are as follows: the guide needle comprises a needle body with a flat obtuse-angle needle head and a grab handle, the flat obtuse-angle needle head is provided with an oval needle hole, and the edge of the oval needle hole is polished and smoothly transited; a fixed needle core is arranged in the needle body; the end, located in the grab handle, of the needle body is fixedly connected witha hollow connecting end. A connector is arranged at the end part of the fixed needle core; a sliding rail is arranged on the inner wall of the grab handle; and a strip-shaped groove, a first slidingbutton and a second sliding button are arranged on the wall surface of the grab handle. When the guide needle draws a sawtooth line for routing, the sawtooth line is not prone to being cut off by theedge of a needle hole in the needle head of the guide needle, the guide needle draws the sawtooth line conveniently for forward and reverse routing operation, one end of the sawtooth line can be stably fixed to the needle hole, and the line carving operation quality is guaranteed conveniently; meanwhile, the length of the needle body of the guide needle can be adjusted according to needs, operation is convenient, and tedious operation of replacing guide needles of different lengths is avoided.

Description

technical field [0001] The invention relates to the technical field of medical plastic devices, more specifically, it relates to a guide needle for thread-carving zigzag threads with smooth needle holes. Background technique [0002] As one of the minimally invasive techniques for thread embedding in cosmetic surgery, "thread carving" has clinical advantages such as easy operation, good facial lifting and firming effect, quick effect, and few complications. admired by those who With the development of minimally invasive surgery, thread embedding facial rejuvenation surgery (commonly known as "thread carving") has become an important surgical method for facial rejuvenation. Thread embedding beauty, also called embedding thread lifting, is the latest method to use minimally invasive puncture and bury zigzag lines in the skin fascia layer (SMAS) to lift the sagging skin, so as to achieve the overall rejuvenation effect such as contour lifting and firming. minimally invasive s...
