Pliers for taking out invisible appliance template accessory

Abstract

The utility model provides a pair of forceps for taking out an invisible appliance template accessory, which belongs to the technical field of medical equipment for dentistry, and comprises two forceps handles which are mutually hinged, the end part of the beak part of one forceps handle is provided with a semispherical bulge part, and the end part of the beak part of the other forceps handle is provided with a semispherical groove corresponding to the semispherical bulge part; the hemispherical protruding part is covered with a sleeve cap completely attached to the hemispherical protruding part, and the edge of the sleeve cap is locked to the hemispherical protruding part. A ferrule is arranged at the top end of the edge of the hemispherical groove, and the edge of the ferrule is locked to the edge of the top of the hemispherical groove. Compared with the mode that the tip of a probe is used for searching the edge of the accessory to pry the accessory, the accessory prying device is simpler, more efficient and convenient to operate, and meanwhile the danger that the probe slips is avoided; after being separated from the groove, the accessory directly falls into the hemispherical hollow groove, so that the risk that the accessory flies out to hurt people and cause iatrogenic infection when the accessory is pried by a probe is avoided.

Description

TECHNICAL FIELD

[0001] The utility model relates to dental medical instrument equipment technical field, concretely relates to a kind of hidden appliance attachment template take-out forceps that can be taken out from the attachment of invisible appliance, can shorten the bonding time of invisible appliance attachment, improve clinical operation efficiency and avoid the danger caused by the flying of slipped attachment.The utility model discloses an invisible appliance template attachment take-out forceps. BACKGROUND

[0002] Malocclusion refers to various deformities caused by the relationship between teeth, jaws and craniofacial not adjusted, and malocclusion not only affects oral function and facial appearance, but also has a certain impact on individual social psychology. In recent years, the toothless invisible appliance has attracted more and more patients due to its convenient oral cleaning and aesthetic appearance, and more and more clinical orthodontists also choose to use the toothless invisible appliance.

[0003] Since the toothless invisible appliance is a removable appliance, in order to increase the retention of the toothless invisible appliance and the treatment efficiency, it is necessary to bond the attachment on the tooth surface. When bonding the attachment, the tooth surface needs to be etched and dried first, then the resin is filled into the groove of the attachment template of the toothless invisible appliance, then the attachment template is worn into the patient's mouth, and finally the resin attachment is photocured and the attachment template is taken out. Since the attachment bonding requires a good etching surface on the tooth surface and strict moisture isolation throughout the process, if the etching or moisture isolation is not in place, the attachment bonding failure often occurs. Especially when the patient's cooperation is poor and the saliva is more, the attachment cannot be successfully bonded to the tooth surface. When the attachment bonding fails, the cured attachment is often embedded in the groove of the attachment template and is difficult to take out. The inner surface of the attachment template is rough, and a large number of attachments have edges (such as rectangular attachments), so the detached attachment often has a certain adhesion with the inner surface of the attachment template, and a certain force is needed to separate the attachment from the template. At present, the probe tip is mainly used to pry the edge of the attachment to separate it from the template. However, since the inner surface of the attachment template is highly attached to the tooth surface, after being squeezed into the mouth, the resin fills the groove and closely adheres to the inner surface of the template, and there is almost no gap between them. Therefore, it is often difficult for the probe tip to explore between the edge of the attachment and the inner surface of the template to pry the attachment. The doctor increases the clinical treatment time in the process of repeated attempts. In addition, when the probe is used to pry the attachment, the probe is easy to slip due to the large instantaneous force, which may cause scratches and other dangers, and the prying attachment often uncontrollably flies out, which may cause injury to the patient and the doctor (such as flying into the eye) and iatrogenic infection. SUMMARY

[0004] The utility model discloses a purpose lies in providing a kind of invisible appliance template accessory extraction forceps, when invisible appliance bonding accessory is not successful, the problem that the accessory embedded in template is difficult to extract, on the one hand, the operation time of invisible appliance accessory bonding is saved, on the other hand, the problem that the danger caused by the easy sliding and accessory flying out when the accessory is pried on template using probe and other instruments is avoided.

[0005] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The utility model provides a kind of invisible appliance template accessory extraction forceps, including articulated forceps handle, the end of the beak of one forceps handle is equipped with semispherical protruding portion, the end of the beak of another forceps handle is equipped with the semispherical recess corresponding with the semispherical protruding portion;The semispherical protruding portion is covered with the cap that is completely attached with semispherical protruding portion, and the cap edge is locked in semispherical protruding portion;The edge top end of the semispherical recess is equipped with ferrule, and the ferrule edge is locked in the top edge of semispherical recess.

[0007] Further, the semispherical protruding portion is equipped with annular groove, and the edge of the cap is equipped with annular flange that matches the annular groove.

[0008] Further, the edge top end of the semispherical recess is equipped with everted clasp, and one side of the ferrule is equipped with the clamping groove that matches the everted clasp.

[0009] Further, the cap is made of rubber material.
