Problems solved by technology

[0003] Orthopedic surgery uses the navigation system to formulate surgical plans and intraoperative navigation before surgery. It can track surgical instruments during the operation, and update and display the position of surgical instruments on the patient's preoperative or intraoperative images in real time, allowing surgeons to Know the relationship between the position of the surgical instrument and the patient's anatomical structure, and at the same time have a complete navigation function, which can simulate the forward and backward of the surgical instrument, so that the surgical process is more accurate, instead of relying on the doctor's clinical experience to solve the problem, such as , the invention with authorized notification number CN1263433C discloses a robotic orthopedic navigation surgery device, including a computer and medical image processing software stored in the computer, a C-arm X-ray machine, and an operating bed mechanism, which is collected by a C-arm X-ray machine. The image is transmitted to the computer through the acquisition card for medical image software processing. This orthopedic navigation surgical device can accurately locate during the operation, use the computer to process the image, and determine the position and state of the surgical object and surgical instrument in the image space. The accuracy of the operation is increased, but because this orthopedic navigation surgery device uses X-ray equipment, a large amount of X-ray radiation greatly damages the health of doctors and patients, and this equipment is large in size, takes up space, and is inconvenient to move. It is also quite inflexible to use
[0004] Therefore, on the basis of these technical problems, people have invented a positioning device with a smaller volume. For example, the invention whose publication number is CN101332137A discloses a traction reduction navigation device for long bone fractures, which includes active mechanical arms, passive mechanical Arm, photoelectric tracker, end effector, mobile vehicle, tracking marker assembly, spatial point collector, the tracking marker assembly is installed at the fracture of the long bone, the spatial point collector is held in the hands of the doctor, and the active mechanical arm and passive mechanical arm are respectively installed On the mobile vehicle, the photoelectric tracker is installed on the active mechanical arm, the end effector is installed on the passive mechanical arm, and the computer is installed on the mobile vehicle. The device is small in size, and the mobile vehicle can be moved, which is convenient to move or place during use. In the proper position, it does not take up space. Even so, there are still some problems in its use. For example, the overall structure of the device is relatively fragmented, backward, and imperfect, and it is not closely connected with modern orthopedic surgery. There are many restrictions in the use process. In addition, although the active mechanical arm and passive mechanical arm of the device can rotate up and down, left and right, their structure is more complicated, there are many parts, and they are easy to be damaged during use. Moreover, the photoelectric tracker of the device is After being moved to a fixed position during use, it is often accidentally touched or bumped by the doctor because the doctor forgot to move it to the original position or other vacant places, which greatly affects the doctor's operation process. If you use it every time Manually moving the photoelectric tracker before and after use is not only cumbersome and wastes operation time, but also frequently applies force to it, which will cause stress between the photoelectric tracker and the active manipulator or the joints of the active manipulator. damage, so that the service life of the active manipulator is shorter

Abstract

The invention provides a positioning device, belongs to the technical field of a medical apparatus, and solves the technical problems that a conventional positioning device is small in size, inconvenient to use and short in service life. The technical scheme of the positioning device lies in that the positioning device comprises a moving box body, wherein a first moving mechanism, a second movingmechanism and a control mechanism are arranged on the moving box body, a photoelectric tracking instrument and a first display are movably mounted on the first moving mechanism, a second display is movably mounted on the second moving mechanism, and the photoelectric tracking instrument and the second display can both automatically reset. The positioning device has the beneficial effects that real-time images and operation processes are tightly combined, and tracking and operation can be comprehensively performed in a full range manner, so that the operation process is effortless and quick, quick and smooth completing of the operation by a doctor is facilitated, and the positioning device is tightly combined with modern bone operation.

Description

technical field [0001] The invention belongs to the technical field of medical instruments and relates to a positioning device. Background technique [0002] In recent years, with the rapid development of orthopedic technology, while the difficulty and risk of surgery have increased, image-assisted and minimally invasive techniques have become the main direction of orthopedic development. In this case, some medical devices similar to orthopedic navigation systems have emerged. This system can greatly reduce the risk of complex orthopedic surgery and bring a new operating mode to orthopedic surgery technology-visualized surgical technology. [0003] Orthopedic surgery uses the navigation system to formulate surgical plans and intraoperative navigation before surgery. It can track surgical instruments during the operation, and update and display the position of surgical instruments on the patient's preoperative or intraoperative images in real time, allowing surgeons to Know ...
