Portable pincer type tail end back-bending device

Abstract

The invention relates to a portable pincer type tail end back-bending device which comprises pincer handles 1, a joint 2, a long pincer beak 4 and a short pincer beak 3. The forceps handle 1 and the joint 2 adopt the universal design of a commercially available needle holder, so that the holding is convenient, and the operation habits of clinicians are adapted; the long clamp beak 4 and the short clamp beak 3 are innovatively designed to be long and short, and the long clamp beak 4 is bent towards the short clamp beak 3. Therefore, after the whole device extends into a mouth, the two clamp beaks can reach a force application part without pulling the mouth corner of a patient with force, the pain of the patient is relieved, the operation of an orthodontic doctor is facilitated, and the back bending of the tail end of an orthodontic arch wire is convenient and efficient.

Description

Technical Field

[0001] The invention relates to a light pliers end bender for orthodontic archwire end bending in an oral orthodontic department, comprising a pliers handle, a joint and a pliers beak, in particular a light pliers end bender with a long and a short special pliers beak. Background Art

[0002] The end bending technique is a commonly used technique for handling the end of orthodontic archwires in fixed correction in the oral orthodontic department. This technique is widely performed clinically using a needle holder. However, the original design of the needle holder is not suitable for the end bending of the orthodontic archwire. In order to enable the beak of the needle holder to smoothly contact the end of the orthodontic archwire, the patient's mouth corners need to be pulled as much as possible, which increases the patient's pain and often results in poor end bending effects. Later, a series of end bending devices were developed, but they were not widely used in clinical practice due to their large size, easy damage to the gums, and unsatisfactory end bending effects. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new and lightweight clamp-type end return bender, which is designed and improved from a conventional needle holder, which not only conforms to the operating habits of orthodontists, but also can achieve a good orthodontic arch wire end return bending effect.

[0004] In order to solve the above technical problems, the lightweight pliers-type end bender of the present invention comprises a pliers handle, a joint, a long pliers beak and a short pliers beak; the pliers handle and the joint adopt the general design of commercially available needle holders, which is convenient for holding and adapts to the operating habits of clinicians; the long pliers beak and the short pliers beak adopt an innovative one long and one short design, which is characterized in that the long pliers beak is longer than the short pliers beak, and the long pliers beak is bent toward the short pliers beak.

[0005] With such a design, the orthodontist can easily complete the terminal return bend of the orthodontic arch wire: the orthodontist holds and slightly opens the pliers handle, inserts the long pliers beak and the short pliers beak into the patient's mouth to reach the buccal tube of the molar, makes the short pliers beak press against the mesial tooth surface of the buccal tube to form a fulcrum, and makes the long pliers beak press against the orthodontic arch wire extending distally from the buccal tube; and closes the pliers handle with a little force to make the long pliers beak squeeze the orthodontic arch wire extending distally from the buccal tube, thereby completing the terminal return bend of the orthodontic arch wire.

[0006] As described above, the lightweight pliers-type end bender of the present invention is used for the end bending of orthodontic arch wires, and has the following beneficial effects: the long pliers beak is long and curved, and the short pliers beak is short and straight, so that after the entire device is inserted into the mouth, the two pliers beaks can reach the force-applying position without pulling the corners of the patient's mouth with force, which not only reduces the patient's pain, but also facilitates the orthodontist's operation, making the end bending of the orthodontic arch wire convenient and efficient.

[0011] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions under which the present invention can be implemented. Therefore, they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0012] The lightweight pliers-type end bender of the present invention comprises a pliers handle 1, a joint 2, a long pliers beak 4 and a short pliers beak 3; the pliers handle 1 and the joint 2 adopt the general design of commercially available needle holders, which is convenient for holding and adapts to the operating habits of clinicians; the long pliers beak 4 and the short pliers beak 3 adopt an innovative one-long-one-short design, which is characterized in that the long pliers beak 4 is longer than the short pliers beak 3, and the long pliers beak 4 is bent toward the short pliers beak 3.

[0013] Instructions for use of the lightweight pliers-type end return bender: the orthodontist holds and slightly opens the pliers handle 1, inserts the long pliers beak 4 and the short pliers beak 3 deep into the patient's mouth to reach the molar buccal tube 5 on the dentition 7, makes the short pliers beak 3 press against the mesial tooth surface of the molar buccal tube 5 to form a fulcrum, and the long pliers beak 4 presses against the end of the orthodontic arch wire 6 extending distally from the molar buccal tube 5, and closes the pliers handle 1 with a little force to make the long pliers beak 4 squeeze the end of the orthodontic arch wire 6 extending distally from the molar buccal tube 5, thereby completing the end return bending of the orthodontic arch wire.

[0014] The contents not described in detail in this specification belong to the prior art known to those skilled in the art. It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
