Embodiment Construction

[0012] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0013] Such as figure 1 As shown, a three-dimensional adjustable directional traction device for high-position impacted teeth, including a first connecting pipe 1, a second connecting pipe 2 and a third connecting pipe 3, is characterized in that the first connecting pipe 1 The left end is fixedly connected with a grid-shaped mouthpiece 5 for bonding on the tooth surface. The first connecting pipe 1 and the second connecting pipe 2 both include two equal-length internal threaded pipes 11 and a pair of two ends embedded respectively. An externally threaded pipe 12 set inside two internally threaded pipes 11, the thread directions of the two internally threaded pipes 11 are opposite, and the threads at both ends of the externally thr...

Abstract

The invention provides a three-dimensional adjustable directional traction device for high impacted teeth. The device comprises a first connecting pipe, a second connecting pipe and a third connectingpipe, the left end of the first connecting pipe is fixedly connected to a latticed tooth socket used for being bonded to a tooth face, thread directions of two inner thread pipes are opposite, threads at the two ends of outer threaded pipes are matched with threads of the corresponding inner threaded pipes respectively, a three-hole connecting port is formed in the middle of each of the two outerthreaded pipes, annular connecting blocks with the same size are fixedly connected to the right end of the first connecting pipe, the two ends of the second connecting pipe and the left end of the third connecting pipe, every two adjacent annular connecting blocks are overlapped and fixedly connected through a screw and a nut, and a gripper is fixedly connected to the right end of the third connecting pipe. Through the annular connecting blocks and arranged screw holes, the screw is used for fixing, and embedded teeth can be pulled while orthodontic treatment is conducted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a three-dimensionally adjustable directional traction device for high-position impacted teeth. Background technique [0002] Teeth that have passed the eruption period but still fail to erupt in the jaw tissue are called impacted teeth. The teeth that have not erupted need to be pulled out through surgery with a traction device. At present, the traction of impacted teeth is mostly vertical traction, which is subject to greater resistance from the jaw tissue, and the treatment cycle is longer. Some patients are difficult or even unable to be tractioned. Contents of the invention [0003] In view of the above-mentioned defects of the prior art, the technical purpose of the present invention is to provide a three-dimensionally adjustable directional traction device for high impacted teeth. [0004] In order to achieve the above technical purpose, the present invention pr...
