Embodiment 2

[0019] Example 2, such as Figure 7 As shown, the connection between the first steel sheet 11 and the ring 4 is bent into a cavity 41 consistent with the ring 4, and the first steel sheet 11 is provided with a limiting groove 42, and the limiting groove 42 is used to limit the cavity 41. position, so that the first steel sheet 11 can not slide on the ring 4. When the first steel piece 11 is squeezed by the external force given by the locking mechanism 2, it is easy to deform in the vertical direction and hold the broken central screw tightly, while the limit groove 42 ensures that the first steel piece 11 will not be relatively round. Ring 4 is displaced.

[0020] Further, the number of grooves 112 is three uniformly arranged along the circumference of the first steel sheet 11, and the number of ribs 22 is three. The first steel sheet 11 is a cylindrical structure surrounded by three steel sheets. This design is convenient for adjustment according to different teeth, and at ...

Abstract

The invention discloses a device for taking a broken wire of a center screw of an implant. The device comprises a wire taking mechanism, a locking mechanism sleeves the wire taking mechanism, an adjustment sleeve sleeves the locking mechanism, and one end of the wire taking device penetrates through the locking mechanism and is fixedly connected with the adjustment sleeve; the wire taking device comprises a first steel sheet, a ring used for fixing the first steel sheet is arranged at the top of the first steel sheet, and the first steel sheet is vertically arranged to be in a pipe cavity shape in a surrounding mode; a protrusion part is arranged on the inner periphery wall of the first steel sheet, grooves are formed in the outer periphery wall of the first steel sheet, and the distribution direction of the grooves is identical to that of the first steel sheet; openings of the grooves face outwards, the groove depths are gradually reduced in the direction of the free end of the firststeel sheet, the groove depths of the portions close to the free end of the first steel sheet are equal, and the locking mechanism is provided with flanges matched with the grooves. The technical demand of the device is low, the device is easy and convenient to operate, and the bad influence such as implant loosening cannot be caused.

Description

technical field [0001] The invention relates to the field of dental implants, in particular to a device for removing broken wires from the central screw of the implant. Background technique [0002] Oral implants, also known as dental implants, are the third set of teeth for humans. It is a technology that implants implants into the jawbone through surgery, and after forming osseointegration, installs a restoration on its upper part to simulate human teeth and restore chewing function. The commonly used planting material is TiAl 4 V 6 . The composition of the implant includes two parts: the body and the central screw. The central screw of the implant is the occlusal stress concentration point and is prone to fracture. At present, the method of breaking the central screw of the implant mostly adopts the method of high-speed turbine and ultrasonic vibration, but this method requires high operation, time-consuming, and the patient's comfort is poor, and it is prone to adver...
