Fluid-absorption type minimally invasive tooth extraction device

Abstract

The invention relates to the field of medical appliance and equipment, and particularly relates to a fluid-absorption type minimally invasive tooth extraction device. According to the device, a root canal pin is driven into the root canal of the residual root of a tooth, and is driven by the pulling force generated by constant rotation of a screw mechanism, so that the residual root of the whole tooth is pulled out, the effect of efficiently absorbing saliva and blood can be achieved, and the working efficiency is improved; a screw handle is connected with a screw telescopic rod, and the screw telescopic rod is connected with the root canal pin through a snap ring; a fluid absorbing nozzle is communicated with a conduit; a fluid storage bag and an external straw are communicated with each other; the conduit is connected with the fluid storage bag through a holding handle; the screw telescopic rod and the conduit are respectively arranged on two sides of a main rod; a telescopic racket arranged inside the main rod and the holding handle arranged at the outer end of the main rod have a supporting effect; two ends of the telescopic bracket extend out of the main rod; a compression spring is connected outside the middle of the telescopic bracket in a sleeving manner; and convex rings connected with the compression spring are respectively arranged on the telescopic bracket and the middle part of the main rod.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a liquid-absorbing minimally invasive tooth extraction device. 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 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 locat...

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

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.

Moreover, during dental operations, a large amount of saliva and blood are produced in the patient's mouth, which must be removed from the patient's mouth to prevent blockage, choking, or unpleasant swallowing, and require the patient to spit out from time to time, so that the doctor must interrupt Surgery, waiting for the patient to spit out the saliva in the mouth before performing the operation will affect the efficiency of the dental operation and bring inconvenience to the doctor
