Tooth implantation drilling robot based on small cavity

Abstract

The invention relates to a tooth implantation drilling robot based on a small cavity. The robot comprises a bearing chassis, a mechanical arm, a clamp, a drilling executor, a control box, a chassis turbine box and a driving arm base. The lower portion of the chassis turbine box is fixed to the bearing chassis. The upper portion of the chassis turbine box is connected with the driving arm base. The upper portion of the driving arm base is provided with a connection hole. The control box is connected with an external computer through a wire and meanwhile fixed to the chassis turbine box. One end of the mechanical arm is connected with the connection hole in the driving arm base. The other end of the mechanical arm is connected with one end of the clamp. The other end of the clamp is connected with the drilling executor. The tooth implantation drilling robot is characterized in that the drilling executor comprises a medical special brushless motor, a speed reducer, a rear axle housing, a front axle housing, a machine head shell, a drill bit, a small connecting rod, a crank, a large connecting rod, a rear transmission shaft, a front transmission shaft, a bevel gear, a one-piece gear spindle and a universal joint pin. The medical special brushless motor is connected with one end of the rear transmission shaft through the speed reducer, and the other end of the rear transmission shaft is connected with one end of the front transmission shaft through the universal joint pin.

Description

Technical field [0001] The invention relates to the technical field of drilling machinery for medical and surgical operations, in particular to a dental implant drilling robot based on a small cavity. Background technique [0002] At present, the prevalence of dental and jaw deformity in my country exceeds 60%. Fixation device technology is the most common and effective method of tooth restoration and correction. However, tooth damage caused by trauma requires tooth implantation. Robotic tooth implantation is a robot technology. A brand new application in the medical field. [0003] Implant dentures are implants (artificial tooth roots) placed in the alveolar bone of the oral cavity. After a few months, the osseointegration is completed, and then the artificial tooth root is installed with the denture. [0004] In the process of tooth implantation, it is very important to implant the artificial tooth root in the ideal position. In addition, the quality of the drilling directly determ...

Problems solved by technology

The image-guided dental implant robot researched by Old Dominion University in the United States is a relatively advanced set of robots so far, but it has not been used in clinical practice, and it is still in the experimental stage in general. Except for the rotation of the drill bit, the drilling actuator itself No degree of freedom, can not do bending movement, which limits the flexibility of the whole robot

On the one hand, the cavity space of the human oral cavity is small, and the structure varies from person to person. Some positions are difficult for the robot to reach and perform drilling operations. Moreover, the reduced flexibility of the drilling robot will limit its application in other surgical operations

On the other hand, in the real oral surgery, the field of view of the implant robot will be blocked due to the lack of flexibility at the end, which will make the operation more difficult and affect the quality of the operation
