Bone meal conveyor

Abstract

The invention relates to the technical field of dental instruments, in particular to a bone meal conveyor. The bone meal conveyor comprises a bone meal container, a conveying component and a stirring component, the bone meal container is vertically arranged on the horizontal plane and is in an inverted cone shape, a first containing cavity is formed in the bone meal container, the conveying component is arranged in the first containing cavity in the bone meal container, a hollow structure is arranged at the output end of the conveying component, the taper of the conveying component is consistent with that of the bone meal container, the stirring component is arranged in the hollow structure at the output end of the conveying component, the distance entering the maxillary sinus can be accurately controlled by utilizing an outer ring sleeve on the outer side wall of the conveyor, and the maxillary sinus is prevented from being damaged in the conveying process; the bone meal is filled into the maxillary sinus, a funnel-shaped outlet is large, the bone meal can be rapidly and effectively conveyed into the maxillary sinus for filling at a time, the speed is high, powder falling is avoided, operation of medical staff is facilitated, the bone meal filling effect is good, the filling operation time is greatly shortened, and the bone meal in the maxillary sinus can be evenly stirred.

Description

technical field [0001] The invention relates to the technical field of dental instruments, in particular to a bone powder conveyor. Background technique [0002] In the field of oral medical restoration, as an effective treatment method, dental implants are playing an increasingly important role. Dental implants are used to implant implants similar to tooth roots in the case of patients with single tooth loss or dentition defects. Dental body to replace the natural tooth root, and through activities such as the installation of dentures to restore the chewing function of the teeth. [0003] For the same implant needs, but in the case of severe maxillary bone loss, maxillary sinus lifting surgery is required to achieve the desired purpose. In the traditional external lifting operation, a window is opened on the outer bone wall of the maxillary sinus. The shape of the window is generally round or oval. The operation usually uses a ball drill to open a window on the outer bone ...

AI Technical Summary

Problems solved by technology

[0006] When lifting the bone graft to the maxillary sinus, there is a great correlation between the success rate of the externally lifted bone graft and the uniform distribution of bone powder in the maxillary sinus. The delivery of bone powder requires the use of a bone powder conveyor. The powder mouth is small, and the bone grafting time is very long. It takes many times to complete a bone graft, and the powder loss is very serious. More importantly, the current bone powder conveyors rely on the experience of doctors to control the entry into the maxillary sinus. distance, low security
