Description
Technical Field
The present invention relates to the field of medical devices, and more particularly, to a dental drill capable of collecting bone fragments after drilling to the maximum.
Background
Teeth are a part of the digestive system, and mainly can be used for smoothly eating food after a series of cutting, chewing and grinding actions are carried out on the food during eating, and the teeth also have the functions of keeping beauty, helping pronunciation and the like, so the teeth are one of essential important organs of a human body.
However, it is believed that many people have problems such as failure to provide original teeth for use due to tooth related diseases, or tooth loss due to collision, and if such a phenomenon occurs, it is often necessary to implant a dental implant (which is used to replace the root of the original tooth after extraction) in the oral cavity by means of artificial tooth implantation, and during the tooth implantation process, a dentist connects a dental drill with a surgical instrument (drill) to drill the alveolar bone of the affected part in the oral cavity of the patient, so that the dental implant can be conveniently locked on the alveolar bone after drilling.
The known structure as described above still has the following problems in practical use: the tooth bone drill no matter is a twist drill or a straight flute drill, the tooth bone drill does not have the function of properly collecting the bone chips which are drilled, so that the bone chips can be washed by water flow during drilling, loss is easy to occur, when the alveolar bone of a patient needs to be subjected to bone supplementing procedures by taking the bone of the patient self due to periodontal diseases or tooth missing for too long time, the problem that enough self bone chips can not be used often occurs, the implantation of the self bone chips has a good proliferation promoting effect and cannot be replaced by other substitute materials, and therefore improvement and innovation breakthrough are necessary.
Therefore, the inventor of the present invention has thought and created the idea that the invention is developed by designing through years of experience, and through many studies and trials of sample tests and many correction and improvement.
