Abstract

The invention discloses an arch wire shaping device with two pressure levers arranged on the same end, relates to a medical device for dentistry, and aims to solve the problems that during the shaping process of an arch wire for orthodontic clinic treatment, the operation is troublesome, the control is not easy, and fingers are susceptible to injury duo to operation for a long time. According to the arch wire shaping device, two handles, rings and the pressure levers are connected to a cylindrical shaping piece; grooves are formed in the cylindrical shaping piece; the pressure levers are tangential to the circumference of the outer surface of the cylindrical shaping piece; after the arch wire is put in the grooves, a user can hold a fixed handle by one hand and turn the rings with two fingers of the other hand, and the pressure levers drive the arch wire to turn to two sides to enter the grooves, thus the arch wire can be arch-shaped through one-step operation. Therefore, not only is the form symmetry of the arch wire guaranteed but also the shaping steps are simplified; the operation time of a dentist is reduced, requirements on operative skills of the dentist are reduced, and the fingers of the dentist are prevented from injure. The arch wire shaping device saves time and labor, and can be widely used for shaping arch wires for orthodontic clinic treatment.

Description

technical field [0001] The invention relates to a dental medical instrument, in particular to an arch wire former designed with two pressing rods at the same end. Background technique [0002] With the development of orthodontic medicine, the application of arch wire in orthodontic clinic is an essential and important part. In clinical orthodontics, the arch wire needs to be bent to a certain shape before correction, and a special arch wire shaper must be used for bending. At present, the structure of the arch wire shaper used clinically is: the whole is dumbbell-shaped, the cylindrical shape in the middle is connected to the handles at both ends through the shaft, and only one handle is provided with a pressure rod, and the clinician places the arch wire on it. The size matches the groove of the plastic part, and then press one end of the arch wire with the thumb of the left hand, and the pressing rod is driven to rotate on the surface of the plastic part by turning the ha...
