Description

Orthodontic ligature wire former

technical field

The utility model relates to an orthodontic medical auxiliary device, in particular to a bracket ligation wire forming device for orthodontic treatment.

Background technique

With the improvement of our country's living and cultural level, people's requirements for quality of life are constantly improving, and the number of patients who require orthodontic treatment is increasing day by day. For patients who adopt fixed orthodontics for malocclusion correction, in the process of orthodontic treatment, it is necessary to use ligature wires to tie the archwires to the brackets bonded to the surface of the teeth, so as to control the movement of the teeth and achieve orthodontic treatment. goals and effects. Most of the orthodontic ligature wires used for ligating orthodontic arch wires are coiled orthodontic ligature wires produced by the factory. Orthodontists must make them into specific lengths and shapes in advance or temporarily when they are used clinically. Facilitate the ligation of orthodontic archwires. This method of forming ligature silk not only increases the workload of medical staff, but also prolongs the diagnosis and treatment time of patients. At present, most of the forming ligature silk is manually formed, which is easy to cause non-standard shape and low efficiency. It is easy to cause the waste of ligation silk, and the disinfection treatment is inconvenient, and it is easy to cause nosocomial infection.

Contents of the invention

The purpose of the invention of the present utility model is to provide an orthodontic ligature wire forming device capable of realizing rapid molding of oral orthodontic ligature wire and improving the efficiency of diagnosis and treatment in view of the above-mentioned existing problems.

The technical scheme adopted by the utility model is as follows: an orthodontic ligation wire forming device includes a wire wrapping frame, and the wrapping wire frame is composed of A bar, B bar, C bar and D bar arranged in clockwise order In a square frame, B pillars and D pillars are arranged on the inner sides of the B poles and D poles, the B pillars are parallel to the B poles, the D pillars are parallel to the D poles, the distance between the B pillars and the B poles and the distance between the D pillars and the D poles The distances are equal, both 5-6mm.

As a preference: a handle is also connected to the C rod.

Further: the parts of the B rod and the D rod close to the A rod are respectively provided with a groove, and the A rod is a telescopic rod.

When making the finished ligature wire, you only need to hold the handle with your left hand, and wrap the ligature wire across and around the B and D rods with your right hand. At the groove, after winding a certain amount, pressurize the ligature wire wrapped on the frame at the upper and lower parts of the bulging parts of the B rod and D rod (by hand or tweezers), so that they are close to each other, forming a small head with a small waist and a large tail. Moderate three parts, after forming, the ligature wire exits the former. The A rod is set as a telescopic rod, and the A rod can be shortened when withdrawing, which can conveniently withdraw and prevent the formed ligature wire from being deformed. Then cut off the junction of the tail of the ligature wire, and then bend the head upwards at an angle of 30-45°. The length of the ligation wire produced by this method is 50mm, the width of the head is 1mm, the length is 5-6mm, the width of the waist is 5mm, and it is at a certain angle with the head. More convenient. the

In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is that the medical staff can prefabricate the coiled orthodontic ligature into a ligature of a specific shape and length necessary for orthodontics clinically, that is, The middle is big and the two ends are small, so that orthodontists can quickly perform ligation, thereby saving diagnosis and treatment time, improving work efficiency, and saving manpower and material resources.

The orthodontic ligature wire forming device is very convenient to use, can greatly improve work efficiency, has the characteristics of simple structure and material acquisition, easy manufacture and low cost, and the like.
