A kind of molar band pliers

Abstract

The invention relates to a pair of molar-band forceps, and belongs to the field of orthodontic medical instruments. The molar-band forceps comprise forcep heads and forcep handles, wherein the forcep heads and the forcep handles are connected through a hinged shaft. The molar-band forceps are characterized in that the forcep handles consist of an upper forcep handle and a lower forcep handle, and tooth buckles which cooperate mutually are arranged at the middle rear parts of the upper forcep handle and the lower forcep handle; the forcep heads consist of an upper forcep piece and a lower forcep piece, a main pushing head extending downwards and forwards is arranged at the most front end of the upper forcep piece, and an auxiliary pushing head which can slide forwards and backwards is arranged on the lower plane of the lower forcep piece. The molar-band forceps disclosed by the invention have the benefits that the molar-band forceps not only have the function of clamping a band, but also can easily wear the band on a molar through the two pushing heads, so that the replacement of instruments during operation is reduced, the operation time is shortened, and besides, the edge of the band is unlikely to roll; in addition, the coating of bonding agents, the bonding of the band, and the transmission of the band by medical workers are facilitated; the molar-band forceps are simple in structure and convenient to use, and have a higher popularization value in orthodontic clinical works.

Description

technical field [0001] The invention belongs to the field of orthodontic medical instruments, in particular to a molar band forceps. Background technique [0002] In the process of orthodontic treatment, no matter what kind of orthodontic system, the belt ring is a very important part of it, and the belt ring is the most commonly used retention accessory for anchorage molars. The band is made of stainless steel sheet or metal alloy sheet and sticks snugly to the tooth. Accessories such as buccal tubes, brackets, and draw hooks can be welded on the belt ring, and these accessories are fixed on the tooth surface through the belt ring. Before bonding the belt ring, it needs to go through a tedious process of try-on, trimming, taking it out, rinsing and drying, applying adhesive, and then putting it on the molars. The bands commonly used in clinical practice are generally prefabricated bands of different types by the manufacturer. The doctor chooses to try them on according to...

Problems solved by technology

During the operation, the doctor needs to use the band clipper to push the band into the teeth. When taking it out, the doctor needs to use the band removal pliers to take out the band. If the band is found to be inappropriate, it needs to be re-selected and tried again, because it needs to be used every time it is tried. A variety of appliances, the replacement of appliances not only increases the operating time of the doctor, but also takes a long time for the patient to open his mouth, which increases the pain

[0003] In addition, the material of the orthodontic ring is stainless steel sheet or metal alloy sheet, which itself has a certain thickness. When it comes down to the contact point, it needs to use a large force to make the ring go to the gingival end of the tooth. Due to the anatomical factors of blocking and its crown, when using a common band clipper, only one side of the band is stressed, so it is easy to cause the metal sheet to curl

In addition, due to the complex anatomical shape of molar crowns, the high points of the crowns are not on the same horizontal line, so the rings cannot fit well with the crowns, especially the inverted crowns below the high points. In the concave area, the ring cannot be closely attached to the crown

[0004] Furthermore, when putting a suitable ring on the patient's teeth, the conventional method is that the nurse puts on gloves, holds the outside of the ring with fingers, applies adhesive on the inner surface of the ring, and directly Handing it to the doctor, this method has the following disadvantages: first, the adhesive is easy to stand on the glove; second, because the belt loop is relatively small and round during the transfer process, it is easy to cause the belt loop to slip off if you are not careful
