Problems solved by technology

There are many problems in using the above instruments to extract teeth. First, the extraction operation mainly depends on the dentist’s experience and technology. It needs a long clinical training to master it proficiently. It is difficult for young doctors to master it. Second, if you encounter a broken tooth root, Above-mentioned instrument can't locate on the residual root, often very troublesome, needs to cut gingiva sometimes, brings a lot of misery to patient; The 3rd, no matter adopt tooth lifter, chisel, hammer or tooth extraction forceps etc. all can cause wound when extracting the residual root of anterior tooth The area is large, which brings pain to the patient and affects the appearance; therefore, it is necessary to seek a minimally invasive tooth extraction device
[0003] The current minimally invasive tooth extraction mainly uses the wedge force and slight rotational force of the minimally invasive tooth extraction knife to cut off the periodontal ligament and squeeze the alveolar bone to increase the gap at the same time, and then use the tooth extraction forceps to extract the tooth with a slight force, although this This minimally invasive tooth extraction method greatly reduces the damage to the periodontal tissue during the entire tooth extraction process. However, due to the use of tooth extraction forceps to extract teeth, it will inevitably touch the patient's gums, causing varying degrees of damage, which brings a lot of pain to the patient. Painful, and minimally invasive tooth extraction instruments are imported, expensive and cannot be popularized, and there is no special tool for root extraction on the market

Abstract

The invention relates to a device for removal of a root canal nail. The device for removal of the root canal nail comprises a rack and a screw mechanism; the rack is provided with a screw hole; the screw mechanism penetrates through the screw hole; and the lower end of the screw mechanism is provided with a root canal nail connecting mechanism. In the implementation course of minimally invasive tooth extraction, the root canal nail is inserted into the root canal of a residual root to closely connect the root canal nail connecting mechanism and the root canal nail; and the tension produced by continuous rotation of the screw mechanism drives a drag hook to pull the root canal nail, so as to remove the root canal nail and extract the whole residual root.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a device for pulling out root canal nails. Background technique [0002] At present, when extracting teeth in oral clinical surgery, the principle of lever mechanics is applied, and the instruments used usually include tooth lifters, chisels, hammers, and tooth extraction forceps. The method is to place the tooth lifter and the chisel at the interdental space and the corresponding alveolar ridge, forcefully pry or chisel the tooth loose, and then hold the pliers, or shake or twist and pull, to extract the affected tooth. There are many problems in using the above instruments to extract teeth. First, the extraction operation mainly depends on the dentist’s experience and technology. It needs a long clinical training to master it proficiently. It is difficult for young doctors to master it. Second, if you encounter a broken tooth root, Above-mentioned instrument can't ...
