Artificial cochlea implanting operation system based on computer vision

Abstract

The invention relates to an artificial cochlea implanting operation system based on computer vision. The artificial cochlea implanting operation system is characterized by comprising a computer, a head fixed support, a rough adjustment passive arm, a dual-plane rotor, a CT (Computed Tomography) scanner and photo-electric navigation equipment, wherein the computer is further internally provided with a VTK Platform rectification navigation platform; the VTK Platform rectification navigation platform comprises an image visualization unit, an image incision unit, a spatial rectification unit, a planning unit and a navigation unit, wherein the image visualization unit is used for reading, rebuilding and displaying the CT data of a patient, the image incision unit is used for incising the CT data of the patient and acquiring the data of an operative region, the spatial adjustment unit is used for combining a CT image space and an actual space so as to generate a rectification matrix, the planning unit is used for planning the operative pathway of an implanted artificial cochlea in the CT image space, and the navigation unit draws a model by combining the cochlea surface of the patient under the tracking of the photo-electric navigation equipment, and guides a doctor to finish the implanting operation of the artificial cochlea according to a planned path. The artificial cochlea implanting operation system based on computer vision can be extensively applied to artificial cochlea implanting operation.

Description

technical field [0001] The present invention relates to a cochlear implant surgery system, in particular to a computer vision-based cochlear implant surgery system. Background technique [0002] Hearing disability ranks first among the five major disabilities in my country. According to the Second National Sampling Survey of Disabled Persons in 2006, there are 27.8 million hearing disabilities in my country, 1 million children under the age of 12, and the incidence of congenital hearing impairment in children is about 0.1. %~0.3%, the incidence of severe to very severe hearing impairment is about 0.1%, and nearly 30,000 deaf children are born every year in my country due to various reasons. Do not accept the fate of being deaf. [0003] Cochlear implants can effectively treat severe and severe deafness. It began in the 1950s. After decades of development, it has not only become an electronic device with the highest bionic technology, but also the most successful neural implan...

AI Technical Summary

Problems solved by technology

The total number of cochlear implant cases in China is about 1,000. Compared with the huge base of hearing disabilities in China, the number of patients who can be treated is only a drop in the bucket, and most patients have to face surgical trauma, long-term anesthesia, The risk of slow recovery, the main reasons for the above risks are: 1. Cochlear implantation is a high-tech, difficult operation and high-risk operation. This operation requires extremely high skill and experience for the operator. The operator must have rich experience and proficiency in temporal bone dissection techniques. The above-mentioned technical bottlenecks limit the popularity of this operation and reduce the number of people who benefit from the operation.

2. Due to the complex structure of the human temporal bone, the hard bone, the close adjacency of important internal structures, and the narrow location of the cochlear region, electrodes need to be inserted slowly with the help of a microscope. The operation process is not only time-consuming and laborious, but also requires doctors to be steady and precise. As a living organism, it has the characteristics of being unable to tolerate fatigue and poor operational stability, which undoubtedly increases the risk of surgery

3. Traditional cochlear implant surgery requires partial resection of the mastoid and open recesses. It needs to grind away part of the temporal bone and form a "pit" leading to the cochlea from the outside.

In 2011, Nguyen of France used a computer-aided navigation system to guide the operator to avoid the facial nerve and reach the cochlea through the keyhole path. Under the system, continuous monitoring of the electric drill, manual operation of the surgical drill, the feasibility of opening the keyhole to reach the cochlea through the cortex, and the accuracy of the target during the evaluation period, although they used the fiducial marker system to improve the accuracy of the navigation drill, but There are still shortcomings of manual control positioning, which hinders the further improvement of accuracy
