Three-dimensional modeling orthopedic drilling apparatus with high guidance positioning accuracy

Abstract

The invention discloses a three-dimensional modeling orthopedic drilling apparatus with high guidance positioning accuracy, and belongs to the medical equipment. The three-dimensional modeling orthopedic drilling apparatus comprises an electrical drilling machine and an intelligent control circuit arranged on one side of the electrical drilling machine, wherein a connector is fixedly mounted on anoutput shaft of the electrical drilling machine, a fixed rod is in sleeve joint with the surface of the connector, and a first drill bit is in embedded connection with the inner side of the fixed rod. According to the three-dimensional modeling orthopedic drilling apparatus, by mutual cooperation of the designed first drill bit, a second drill bit, a vibrator, a motor, a displacement sensor, a microcontroller and a slide groove, a large trauma area caused during drilling the bone surface can be avoided, besides, drilling depth can be automatically controlled, and higher degree of damage of the interior of bone due to larger depth value of the hole is prevented; and besides, with assistance of three-dimensional modeling and VR technologies, when a medical worker performs drilling, the states of the first drill bit and the second drill bit during drilling in the bone can be observed clearly, and drilling angle can be further guaranteed.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a three-dimensional modeling orthopedic drilling device with high guidance and positioning accuracy. Background technique [0002] Orthopedics, also known as orthopedic surgery, is a specialty or discipline of medicine, specializing in the study of the anatomy, physiology and pathology of the musculoskeletal system, using drugs, surgery and physical methods to maintain and develop the normal form and function of this system, and treating this system. A systemic injury. [0003] Three-dimensional modeling is the process of using drawing software (such as CAD) to create a spatial model. [0004] With the development and progress of science and technology, orthopedics has made great progress in diagnosis and treatment. During orthopedic treatment, it is often necessary to drill bone. However, the existing orthopedic bone drill device is still used. There are some shortco...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve the existing orthopedic bone drilling device in the process of use, there are still some shortcomings, because the surface of the bone is relatively smooth, and has a certain hardness, it is easy to appear when drilling. The phenomenon of slipping and dislocation leads to a large wound on the surface of the bone, and when drilling, the depth of the hole is uncontrollable. Since the inclination of the drill bit inside the bone cannot be observed, the drill bit is prone to tilt.
