Problems solved by technology

The operation has extremely high requirements for the performer. It is necessary to insert the electrode deeply into the scala tympani without damaging the electrode. While not damaging the electrode and the implant, the electrode and the surrounding area of ​​the implant must not be damaged. Structures, such as the scalp, external auditory canal, tympanic membrane, facial nerve, etc. Therefore, there are certain risks in the surgical process, such as damage to the vestibular system or facial nerve, etc., and a good solution has not yet been found

Abstract

The invention discloses a titanium pin registration device and method used for artificial cochlea navigation surgery, and belongs to the field of implantation surgery systems. The titanium pin registration device used for the artificial cochlea navigation surgery comprises a head rest, titanium pins, a probe, gauge points, a binocular tracking sensor and a computer analysis module, wherein the titanium pins are used for being implanted into the backs of the lateral auricles of a patient; the probe is installed on one side of the head rest, and is used for being connected with the titanium pins; the gauge points comprise gauge points which are installed on the probe and the head rest respectively, and the binocular tracking sensor is used for collecting space coordinates of the gauge points; and the computer analysis module is in communication connection with the binocular tracking sensor, through connection between the probe and the titanium pins in the head, space coordinates and positions of the titanium pins with the head rest as a reference system are calculated, and the space coordinates and the positions of the titanium pins and acquired three-dimensional space coordinates and positions of the cochleae and the surrounding tissue of the patient are subjected to registration. According to the titanium pin registration device and method used for the artificial cochlea navigation surgery, by means of the gauge points on the probe and the head rest, by unifying CT images of the titanium pins and the cochleae of the patient into the reference coordinate system, a surgery tool can be precisely positioned, and navigation is conducted according to preoperative planning, so that operation of a doctor is facilitated.

Description

technical field [0001] The invention relates to the field of cochlear implant surgery systems, in particular to a titanium nail registration system and method for cochlear navigation surgery. Background technique [0002] The cochlea is an integral part of the peripheral auditory system, and its core is the organ of Corti, which is the organ of auditory transmission. It converts the sound signal from the middle ear into a corresponding nerve electrical signal, and sends it to the central auditory system of the brain for further processing. The pathological basis of most sensorineural deafness is the saccade or functional defect of hair cells. The cochlear implant can convert the sound into a certain coded electrical signal by the external language processor, and directly excite the auditory nerve through the electrode system implanted in the body. To restore or rebuild the hearing function of the deaf. [0003] The essence of cochlear implant surgery is to place the inner p...
