A three-dimensional modeling orthopedic drilling device with high guiding and positioning accuracy

Abstract

The invention discloses a three-dimensional modeling orthopedic drilling device with high guidance and positioning accuracy, which belongs to medical equipment and includes an electric drill and an intelligent control circuit provided on one side of the electric drill. The output shaft of the electric drill is fixedly installed with a connection head, the surface of the connecting head is sleeved with a fixed rod, and the inner side of the fixed rod is embedded with a first drill bit. In the present invention, through the cooperation between the first drill bit, the second drill bit, the vibrator, the motor, the displacement sensor, the micro-controller and the chute, it is possible to avoid causing larger damage when opening holes on the bone surface. Trauma area, and can automatically control the depth of the hole to prevent the depth of the hole from being large, causing a high degree of damage to the inside of the bone, and using 3D modeling and VR technology to make the medical staff when performing the hole, The states of the first drill bit and the second drill bit when drilling holes in the bone can be clearly observed, and the drilling angle can be further ensured.

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.
