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 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 The 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 and bringing a lot of pain to the patient. , and the minimally invasive tooth extraction instruments are all imported and expensive and cannot be popularized. There is no special residual root extraction tool in the market

Abstract

The invention relates to a minimally invasive tooth extraction device. The minimally invasive tooth extraction device comprises a root canal nail and a root canal nail removal device. The root canal nail removal device comprises a bracket and a screw mechanism; the bracket 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 connection mechanism. For the extraction of tooth residual root, the root canal nail is inserted into the root canal of the tooth residual root, and the tension force produced by continuous rotation of the screw mechanism drives the root canal nail connection mechanism to pull the root canal nail, so as to extract the tooth residual root. The device has the advantages of simple structure, reasonable design, and minimal invasion in the process of tooth extraction, and greatly improves the comfort degree of patients.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a minimally invasive tooth extraction device. Background technique [0002] At present, in dental clinical surgery, the principle of lever mechanics is applied, and the instruments used usually include dental elevators, chisels, hammers, and dental extraction forceps. The method is to place the dental elevator and chisel in the interdental space and the corresponding alveolar ridge top, pry or chisel the teeth forcefully, and then hold the dental forceps, or shake or twist and pull, to extract the affected tooth. There are many problems with the use of the above-mentioned equipment for tooth extraction. First, the extraction operation mainly relies on the experience and technology of the dentist, which requires a long period of clinical training to be more proficient, and it is difficult for young doctors to master it; second, if you encounter a broken tooth root, T...
