Remote surgical navigation method and device based on in-situ projection technology

Abstract

The invention discloses a remote surgical navigation device based on an in-situ projection technology. The remote surgical navigation device comprises an operating bed, an image device, a connecting rod, an operating end processor, an Internet and a remote end processor, wherein a camera is arranged above the operating bed; the camera head is connected with the operating end processor through theconnecting rod; and the operating end processor is connected with the remote end processor through the Internet. The invention discloses a remote surgical navigation method based on an in-situ projection technology. The remote surgical navigation method is characterized by comprising the following steps that a camera collects on-site color video data; the operation end processor performs signal processing on the color video data; the operation end processor transmits the signal to the remote end processor through the Internet; a doctor at the remote end performs labeling guidance on a screen of the remote end processor according to the real-time image information of the operation end; and the operation end processor processes the received signal and projects an operation instruction of theremote end doctor to a corresponding operation position of the patient through an in-situ projection device.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a remote surgical navigation method and device based on in situ projection technology. Background technique [0002] At present, due to the large population in our country, the economic development and medical resources are extremely unbalanced. The developed cities have abundant medical resources, while the more remote cities with relatively backward economic levels lack medical resources. In addition, patients who need major surgery can only be performed in big cities. Due to the difficulty in seeking medical treatment caused by the region, patients often miss the best time for surgery. [0003] In recent years, with the development and innovation of computer technology, medical imaging technology, satellite communication and other technologies, remote surgical navigation devices relying on these latest technologies are developing in the direction of precision, accuracy and s...

Problems solved by technology

First of all, the traditional remote operation guidance device is based on the teleconferencing system. The remote doctor performs surgical marking according to the surgical scene picture captured by the on-site camera. The operator's perspective must be switched back and forth between the monitor and the operation area, the surgeon cannot perform the operation accurately, and it also brings great inconvenience to the operation process

With the development of augmented reality technology in recent years, remote surgical navigation devices based on augmented reality equipment have also developed rapidly, such as portable wearable devices such as Google Glass and Microsoft Hololens. Surgeons can directly observe the remote operation by wearing these devices. The doctor's virtual surgical guidance and the real surgical area are fused together to guide the doctors on the surgical site to perform the correct surgical operation, but these all rely on the precise registration of the virtual image and reality. Due to the defects of the image registration algorithm, the surgical guidance Inaccurate, unable to complete the operation process accurately
