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

Embodiment Construction

[0011] The present invention will be described in detail below through examples.

[0012] The cochlear implant surgery system of the present invention is the same as the existing surgery system in that it includes a computer equipped with a windows system, a head fixed support, a coarse adjustment passive arm and a pair of planar robots; the head fixed support It is used to support and fix the patient's head during surgery, and it can adopt the existing device structure of the prior art, which is not limited here; one end of the coarse adjustment passive arm is fixed on the operating bed, and the other end is connected to the rear end of the biplane robot , the front end of the biplane robot clamps an electric drill, the coarse adjustment passive arm is used to roughly adjust the position of the electric drill, and the biplane robot is used to fine-tune the posture of the electric drill. The biplane robot can use the fracture surgery that has been disclosed in the prior art Th...

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 invention relates to a cochlear implantation operation system, in particular to a computer vision-based cochlear implantation operation system. Background technique [0002] Hearing disability ranks first among the five major disabilities in my country. According to the second national sample survey of disabled people in 2006, there are 27.8 million people with hearing disabilities in my country, and there are 1 million children under the age of 12. The incidence of congenital hearing loss in children is about 0.1 % to 0.3%, and the incidence rate of severe to extremely severe hearing impairment is about 0.1%. There are nearly 30,000 newborn deaf children in my country due to various reasons every year. Do not accept the fate of being deaf and dumb. [0003] Cochlear implants can effectively treat severe and extremely severe deafness. It began in the 1950s. After decades of development, it has not only become an electronic device with the highest co...
