The invention discloses a jaw moving tooth extractor, and relates to the field of medical instruments. The jaw moving tooth extractor comprises an upper jaw plate, a lower jaw plate, a traction rope,a connecting screw and two connecting pieces, wherein the upper jaw plate and the lower jaw plate are oppositely provided with a plurality of toothed bars; the tip end of each toothed bar is providedwith a through hole; the traction rope penetrates through through holes; two ends of the traction rope are respectively connected with the connecting pieces; and the connecting screw is movably connected to the traction rope. When the jaw moving tooth extractor is in use, the length of the traction rope connected between the two connecting pieces is adjusted according to the oral cavity form and the affected tooth condition of a patient; the tip end of the connecting screw is connected with an affected tooth or a broken tooth of the patient through a wrench matched with the connecting screw, and one end, far away from the tip end, of the connecting screw is fixed to the traction rope; and the patient occludes the jaw moving tooth extractor through upper teeth and lower teeth, and the oppositely-arranged toothed bars are crossed and close to each other and tension the traction rope, so the affected tooth or a residual tooth can be extracted through the connecting screw connected to thetraction rope.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a jaw movable tooth extractor. Background technique [0002] Traditional tooth extraction uses the principle of lever mechanics, and instruments such as tooth lifts, chisels, hammers, and tooth extraction forceps are often used to extract teeth for patients. There are many problems in using the above-mentioned instruments for tooth extraction: 1. The experience and technical requirements of the dentist are high, and the convenience of use is low; The patient brings secondary trauma; 3. The wound area is large and the recovery time is long. [0003] There are still defects in the existing technology, especially in the convenience of using the tooth extraction device, the safety during the tooth extraction process, and the long rehabilitation period after the tooth extraction. Therefore, it is necessary to improve the existing technology and propose a more reasonable technical s...
