Description

Minimally Invasive Extraction Components

technical field

The utility model relates to the technical field of medical equipment, in particular to a minimally invasive tooth extraction assembly.

Background technique

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 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 to pull the affected tooth out. 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 the 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.

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 expensive and cannot be popularized, and there is no special residual root extraction tool on the market at present.
