Central axis extends and extends radially through the open slot of described knotting head.
In one embodiment, the end rounding of described knotting head.
In one embodiment, described handle portion, described connecting rod and described knotting head are made up of stainless steel material.
In one embodiment, described handle portion, described connecting rod and described knotting head are made into integration.
In one embodiment, the cross section of described handle portion is rectangle, and the end of described handle portion is globoidal structure.
In one embodiment, the outer surface of described handle portion is provided with anti-skid structure.
In one embodiment, the outer surface frosted of described handle portion.
In one embodiment, the bottom of described open slot is arcwall face.
In one embodiment, described open slot is U-lag.
In one embodiment, the A/F of the bottom of described open slot is more than the width at the notch of described open slot.
It is preferred that limit the sidewall of described open slot as smooth side wall.
In one embodiment, the length sum of described connecting rod and described knotting head is 15cm-35cm.
It is preferred that the length sum of described connecting rod and described knotting head is 25-32cm.
In one embodiment, a length of 10cm-15cm of described handle portion.
It is preferred that a length of 12cm of described handle portion.
In one embodiment, described handle portion and described connecting rod are cylindrical, and the diameter of described handle portion is more than described company
It is provided with changeover portion between the diameter of extension bar, and described handle portion and described connecting rod.
In one embodiment, described changeover portion is cone.
In one embodiment, the diameter D1 of described knotting head is 3mm-5mm, and the A/F W1 of described open slot is 2mm-
3mm。
The beneficial effects of the utility model:
The A/F of the bottom of the open slot of wire twister of the present utility model, more than the width at the notch of open slot, is opened
The sidewall of mouthful groove is smooth side wall and bottom land is arcwall face so that wire twister can agree with knotting line and not cut during knotting
Cutting knotting line, can arbitrarily adjust knotting position, the end of head of simultaneously tiing a knot uses rounding design so that the end of knotting head pushes away
Not injured tissue when tissue surface.
