In a further technical scheme, the length of the needle tip of the bevel is 3 mm to 5mm, the length of the needle tube is 28 mm to 32 mm, and the length of the pintle is 6 mm to 8 mm.
In the scheme, the lengths of the inclined plane needle point, the needle tube and the needle bolt are selected, so that minimally invasive hair follicle planting operation can be conveniently carried out on the needle part.
In a further technical scheme, the length of the needle rod is 46 mm to 54 mm, and the outer diameter of the needle rod is 10 mm to 14 mm.
In the scheme, the length of the needle rod and the outer diameter of the needle rod are selected, so that a doctor can conveniently hold the needle rod.
The beneficial effects of the utility model include:
1. in the scheme, the outer diameter of the needle tube is selected to be 0.4 mm to 0.6 mm, so that large wound caused to the scalp of a hair-transplant person is avoided, and the postoperative recovery period is shortened; simultaneously, in this scheme, needle bar and pintle be for can pass through fixture realizes dismantling the connection to be convenient for plant the needle and can be right when using needle portion carries out whole change.
2. In this scheme, through the front end of two elasticity arcs and the cooperation of constraint ring, simple and easy realization is right the fixed of pintle and dismantlement.
3. In the scheme, the lengths of the needle point, the needle tube and the needle bolt are selected, so that minimally invasive hair follicle planting operation can be conveniently carried out on the needle part.
4. In the scheme, the length of the needle rod and the outer diameter of the needle rod are selected, so that a doctor can conveniently hold the needle rod.
