Description

Absorbable plastic filling line needle assembly

Technical Field

The utility model relates to the technical field of surgical operations, in particular to a plastic filling tool.

Background

The orthopedic filling wire is a minimally invasive cosmetic procedure for lifting and shaping the face or breast. The orthopedic fill wire uses absorbable polymer sutures to tighten the skin by inserting the suture under the skin and then tightening the suture. The plastic filling line can also stimulate skin to produce collagen, and increase skin elasticity and luster.

The orthopedic filling wire guide is a tool for threading sutures into the skin and is typically an elongate needle catheter. The shaping filling thread guide needle has the functions of smoothly penetrating the suture into the skin, reducing the resistance and stimulation of threading and improving the accuracy and effect of threading; the suture is pulled taut creating tension and a slight lifting effect while maintaining the suture in place under the skin.

During operation, the plastic filling wire needs to be threaded into the plastic filling wire guide needle, and then is transmitted from the needle tail and out of the needle head. The threading process may encounter problems, delay the operation time and affect the operation efficiency. Firstly, the shape of the plastic filling line is special, and some plastic filling lines are provided with barbs or conical structures, so that the suture line can be fixed under the skin, but the threading resistance can be increased, and meanwhile, the breakage of the plastic filling line in the threading process can be increased. And the plastic filling wire guide needle is small in general diameter, and the middle threading hole is smaller, so that threading is difficult, and the proficiency of an operating doctor is very tested. The threading problem not only increases the time of a single operation, but also easily breaks or contaminates the orthopedic filling wire during manual threading, thereby causing infection.
