Description

Connecting piece for planting nails Technical Field The utility model relates to the technical field of orthodontic planting nails, in particular to a connecting piece for planting nails. Background Implant nails are a type of fastening device used in orthodontic treatment, and are typically made of high strength titanium alloys or other biocompatible materials. The implant nail can be implanted into the alveolar bone in a surgical mode, and is used as a stable anchorage point, and the implant nail is combined with traction rubber bands to assist in correcting tooth movement and adjusting jaw positions. The implant nail can provide durable and stable support, and reduce dependence on adjacent teeth, thereby improving the efficiency and effect of orthodontic treatment. In the orthodontic treatment process, the implant nails are easily wrapped by soft tissues after being implanted into alveolar bones, and especially the implant nails in the cheek shed areas of the lower jaw are more easily proliferated by the soft tissues. The planting nails wrapped by soft tissues can influence traction of traction rubber bands in orthodontics, so that the anchorage effect is weakened, and the anchorage effect of the planting nails is difficult to be effectively exerted. Disclosure of utility model The utility model aims to provide a connecting piece for planting nails, which is used for connecting nuts of the planting nails through a protective cover, and then utilizing a connecting rod to extend a force-carrying piece to a direction far away from the planting nails, so that the planting nails wrapped by the proliferated soft tissues can also play the function of the planting nails through the connecting piece by utilizing an indirect anchorage effect. The utility model is realized by the following technical scheme: the utility model provides a connecting piece for planting nail, includes the junction housing, the junction housing is used for being connected to on the nut of planting the nail, be connected with the connecting rod on the junction housing, be connected with the load member on the connecting rod. In the technical scheme, the connecting piece is used as an accessory of the orthodontic planting nail, and the connecting cover is used for being directly or indirectly connected with a nut of the planting nail. The connection cover may be arranged in various ways, and in one or more embodiments, the connection cover may have a structure with a surface having no curved surface, such as a cuboid, a prism, or the like, in which an opening is formed. In some preferred embodiments, the connection cover may have a hemispherical or semi-elliptical structure with an opening formed therein, and the surface of the hemispherical or semi-elliptical structure may be curved. The nut is covered by the connecting cover by placing the nut into the opening of the connecting cover. In a partially preferred embodiment, the bottom of the coupling cap may also be provided with a cylindrical collar, by means of which the cap is provided on the outside of the screw cap. In the technical scheme, the connecting cover and the screw cap are connected by adopting medical resin adhesive for bonding. After bonding, the connecting piece and the planting nails form stable connection. The connecting rod on the connecting cover extends the force carrying piece to a direction far away from the planting nails. The force-carrying piece is preferably provided with an annular structure with an opening so as to sleeve the traction rubber band on the force-carrying piece, and finally, stable traction force is formed on the teeth where the orthodontic buckle is positioned through the cooperation of the traction rubber band and the orthodontic buckle arranged on the teeth. In some preferred embodiments, the length of the connecting rod is adjustable, and the direction of traction force is changed by adjusting the length of the connecting rod, so that the clinical treatment has better flexibility. Through the arrangement, the two ends of the connecting piece are respectively connected with the planting nails and the traction rubber band, and the function of the implant can be exerted through the connecting piece by utilizing the indirect anchorage effect even if the implant is wrapped by the proliferated soft tissue. Meanwhile, the connecting piece is simple in structure and convenient to install, and can realize stable connection of the connecting cover and the planting nail nuts through the medical adhesive, so that the connecting piece has wide application value. Further, the connecting cover is a hollow hemispherical body, a lantern ring is connected to the bottom of the connecting cover, and the inner diameter of the lantern ring is larger than the diameter of the screw cap. In this technical scheme, the connecting cover is hemisphere structure, and the connecting cover is inside to be hollow structure, and its bottom is connected with the lantern ring th
