Orthopedic surgery robot CT imaging, navigation and positioning device and system

Abstract

The invention provides an orthopedic surgery robot CT imaging, navigation and positioning device and system, the device comprises a first mechanical arm, a second mechanical arm, a third mechanical arm and an upper computer, the first mechanical arm is provided with an imaging sensor, the second mechanical arm is provided with an X-ray source, and the third mechanical arm is provided with a channel holding device; the first mechanical arm moves on the first sliding track, the second mechanical arm moves on the second sliding track, the third mechanical arm moves on the third sliding track, the third sliding track is an annular track and is arranged around an operation sickbed, and the first sliding track and the second sliding track are arranged on the left side and the right side of the third sliding track respectively. The upper computer unifies all the components into the same three-dimensional coordinate system, high-quality and high-precision three-dimensional CT images can be completed, X-ray perspective images of various postures in an operation can be flexibly completed, and high-precision orthopedic operation navigation and positioning can be completed by combining high-precision positioning of the mechanical arm with high-quality intraoperative three-dimensional images.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a CT imaging, navigation and positioning device and system for an orthopedic surgery robot. Background technique [0002] With the continuous improvement of social modernization, orthopedic diseases have ranked fourth in the global human death, and have become increasingly prominent problems that seriously affect human life and health; performing orthopedic surgery is a very important way to promote the recovery of patients in clinical medicine. [0003] Traditional orthopedic surgery uses the X-ray perspective of the C-arm machine to guide doctors to complete a series of operations such as bone reduction, pin placement, and fixation. Traditional surgical methods require a large number of X-ray perspectives and rely heavily on the experience of doctors, so there are problems such as long operation time, high radiation dose, and large trauma to patients.

AI Technical Summary

Problems solved by technology

[0009] 1. Traditional orthopedic surgery relies heavily on the experience of doctors. Young doctors need a lot of practice and experience to master the surgery, and the learning cycle is very long. There are still many problems in traditional surgery, such as long operation time, high radiation dose, and large trauma to patients.

[0010] 2. The existing orthopedic surgery robot system is relatively complex, with the help of various image information, the processing is complicated, and not all parts can be used

For example, surgical robots using intraoperative CBCT cannot perform pelvic surgery due to the limited imaging range of CBCT; surgical robots using preoperative CT and intraoperative X-ray images, the positioning accuracy depends on the registration accuracy of CT and X-ray, while Due to various errors, the registration accuracy of 2D X-ray images and 3D CT images is difficult to reach the submillimeter level, which limits the use of this type of surgical robot in some operations that require ultra-high precision.

[0011] 3. Regardless of the traditional orthopedic surgery or the robotic system for orthopedic surgery, the doctor needs to manually drag the C-arm machine to complete the perspective views of various angles and orientations during the operation, and the perspective images of many postures need to be repeatedly perspective, and the C-arm machine will It is not only cumbersome but also requires a long time of operation and learning to master the posture by dragging back and forth, and it also prolongs the operation time
