Method for 3D reconstruction of fracture reduction situation and gesture control image during operation

Abstract

The invention discloses a method for 3D reconstruction of a fracture reduction situation and gesture control image during an operation. The method comprises the following steps of: S1, performing CT scanning on a fracture part of a patient after reduction through a CT scanner, and importing the Diccom data of CT scanning into Mimics21.0 software; S2, converting the Diccom data into three-dimensional data by using the Mimics21.0 software; and S3, realizing intraoperative gesture operation and observing a fracture three-dimensional image by using a 3D gesture somatosensory controller. Accordingto the invention, the CT scanner is used for scanning the fracture part of a patient; unnecessary parts and artifacts of the scanned data are removed through a Mimics 21.0 software processor; the reconstructed three-dimensional image is displayed on a display screen; the 3D gesture somatosensory controller is used for carrying out rotating operation, so that whether the three-dimensional form of the fracture is good or not, whether the reduction is good or not, whether the articular surface is smooth or not and whether the screw is too long or protrudes into the joint or not can be conveniently observed in an operation, sterile operation can be guaranteed, a keyboard does not need to be touched, and the success rate of an orthopedic operation is effectively improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for intraoperative 3D reconstruction of fracture reduction and gesture control images. Background technique [0002] The difficulty of orthopedic surgery is that it is difficult to observe the complete three-dimensional shape of the fracture and the total reduction of Shu through limited incisions. Traditional C-arm and G-arm examinations have shortcomings such as ghosting, unclear display of articular surfaces, and non-stereoscopic images. Intraoperative CT Although the shortcomings of ghosting and unclear display of articular surfaces have been solved, there are still shortcomings of non-stereoscopic images, and the existence of artifacts after plate and screw fixation leads to unclear display around internal fixation. [0003] In the process of realizing the present invention, the inventors found that at least the following problems in the prior art have not been sol...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for intraoperative 3D reconstruction of fracture reduction and gesture control images to solve the problem that the image proposed in the above background technology is not three-dimensional enough, artifacts lead to unclear observation, and it is impossible to know the displacement shape of the observed fracture. And whether the reset is good after reset, whether the joint is smooth, whether there are problems such as the screw is too long or protruding into the joint
