Description

Stretching hook for orthodontic rubber chain

Technical Field

The utility model relates to an oral medicine technical field, concretely relates to just abnormal rubber chain extension hook.

Background

Orthodontic treatment is a treatment for correcting teeth and relieving malocclusion, in which a rubber chain is an auxiliary structure often used by orthodontists, and is often used between a bracket and a supporting groove, between the bracket and a buccal tube, between the buccal tube and a planting nail, etc. due to the elastic action of the rubber chain, so as to generate the movement of teeth. In clinical operation, the traditional three-bend probe cannot hook and fix the rubber chain, the smooth angle of the three-bend probe enables the rubber chain to slip on the probe, and an orthodontist usually uses two tools, namely a mouth mirror end and a needle holder to stretch the rubber chain and fix the rubber chain on a planting nail, a buccal tube or a bracket. The needle holder can well clamp the rubber chain, but the tail end of the mouth mirror only has a traction mouth corner without the function of fixing the rubber chain, so that the phenomenon that the rubber chain cannot be worn on a device such as a planting nail and the like, even the operation time is too long, the rubber chain rebounds to the mucous membrane of a patient is frequently encountered in clinical work, the operation time is increased, psychological pressure is brought to the patient, and the contradiction between doctors and patients is easily caused. The reason for this analysis may be as follows:

(1) no matter what type of rubber chain, the aperture is about 1mm, the diameter of the tip of the traditional probe is smaller than 1mm, namely the probe is placed in a rubber chain hole without problems, but the two ends of the traditional probe are both rounded angles, so that the rubber chain cannot be fixed, and the rubber chain is slipped;

(2) the tail end of the mouth mirror is used for propping against the rubber chain and is unstable, the top of the planting nail can be triangular, polygonal, circular and the like, the propping of the tail end of the mouth mirror against the rubber chain can be influenced by the shape of the top of the planting nail, and the view field can also be influenced by the thickness, the depth and the like of the cheek part, so that the operation is difficult, the rubber chain can not be hung for many times after failure;

(3) one side of the rubber chain is clamped by a needle holder, the force is larger, the other side of the rubber chain is propped against the tail end of the mouth mirror, and at the moment, if the side of the mouth mirror is not fixed firmly, the rubber chain can hurt the mucous membrane of a patient due to elasticity, so that the comfort of the patient is poor, the patient has obvious pain, the psychological condition of the patient is easily influenced, the trust degree of the patient to a doctor is reduced, the compliance of orthodontics is greatly damaged, and even the contradiction between doctors and patients is caused.
