Arch wire tail end bending pliers

Abstract

The invention discloses a pair of arch wire tail end bending pliers. The front ends of pliers handles extend to form clamping arms. The front ends of the clamping arms are provided with pliers beaks which are adjustable in angle and can be assembled and detached. The pliers beaks include the upper pliers beak and the lower pliers beak arranged on the two clamping arms respectively. The edge parts of the upper pliers beak and the lower pliers beak are opposite. A bending pressure edge and a limiting edge are arranged on the edge part of the upper pliers beak in parallel. The height of the bending pressure edge is larger than that of the limiting edge. A fulcrum edge is arranged on the edge part of the lower pliers edge. When the pliers handles are folded together completely, the fulcrum edge is inserted in a gap between the bending pressure edge and the limiting edge, and the pressure connecting face of the fulcrum edge is located between the pressure connecting face of the bending pressure edge and the pressure connecting face of the limiting edge. When the tail end of an arch wire is bent, the passive traction effect on the arch wire can be effectively relieved, and meanwhile the adverse stress effect conducted to an adhesion component on the tooth face is eliminated. More flexible operability is provided for orthodontics doctors, the vision is widened, and pains and fatigues of patients are reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an arch wire end bending pliers. Background technique [0002] Orthodontics is a branch of stomatology, which mainly studies the etiology, diagnosis, analysis, prevention and treatment of malocclusion. Dental instruments are various small portable tools used in stomatology. In clinical applications, the end of the archwire needs to be bent to prevent the archwire from moving and puncturing the buccal mucosa. Under normal circumstances, orthodontists often use wire pliers, trapezoidal pliers, etc. for bending operations. These pliers are not exclusive tools for bending end arch wires. It is not flexible and convenient enough. During the bending process, the passive pulling effect on the arch wire can easily cause the components bonded to the tooth surface to fall off through stress transmission, and it will also increase the pain and fatigue of the patient.

AI Technical Summary

Problems solved by technology

During the clinical operation of the bending forceps, the end of the arch wire is clamped vertically by the beak and the handle is rotated to achieve the bending of the arch wire. During the bending process, the beak will passively pull the arch wire and the stress will give The components bonded to the tooth surface have adverse effects, and at the same time, it is easy to cause the misalignment of the archwire and increase the pain of the patient
