Tibial plateau fracture panoramic visual operation system

Abstract

The invention discloses a tibial plateau fracture panoramic visual operation system which is mainly composed of a device part and an image processing system part. Wherein the device part comprises a lens body, an image acquisition part, an optical fiber, a flushing channel, a drainage channel, a signal transmission line, a central control assembly and a terminal adapter; the image processing system part comprises an image preprocessing module, an image digitalization module, a normalization module, a smoothing module, a restoration module and a denoising processing module; the image depth processing module comprises a feature extraction module, an image segmentation module, an image matching identification module and an image fusion module; the panoramic visual operation system is specially provided for tibial plateau fracture, the defect that no blind operation is provided for any fracture affected part visual field in a traditional operation is overcome, meanwhile, an arthroscope is replaced, and the defect that the visual field of the arthroscope is limited is overcome.

Description

technical field [0001] The invention belongs to the technical field of orthopedic medical devices, and in particular relates to a panoramic visualization operation system for tibial plateau fractures. Background technique [0002] The proximal metaphysis and articular surface of the tibia, this anatomical position is called the tibial plateau in orthopaedics; the tibial plateau is an important load-bearing structure of the knee joint. Arthritis changes; due to the medial and lateral collateral ligaments on the medial and lateral sides of the tibial plateau respectively, and the tibial tuberosity in the center of the platform, on which the cruciate ligament is attached, ligament and meniscus injuries often occur when the tibial plateau is fractured; in addition, tibial plateau fractures are often accompanied by When the tibial plateau fracture is collapsed and displaced, the traditional operation needs to open the cortical bone under the tibial plateau to create a channel, an...

Problems solved by technology

[0003] However, the traditional surgical method is a blind operation, and it is impossible to accurately grasp the depth of the tunnel excavation. If it is too deep, it will easily cause bone loss, and if it is too shallow, it will not be possible to accurately reset the bone collapse. The tool is placed in the collapsed place to achieve controllable prying to make it reset and fit accurately; while arthroscopy can only provide a real-time picture of a single scene, and it is not specifically used for tibial plateau fractures. A single real-time image cannot help doctors grasp the overall situation of tibial plateau fractures, which limits the auxiliary judgment of their operations. In addition, during operations, it is often necessary to flush and drain the affected area to keep the surgical field of view clear
