Description

A tracking stent for robot-assisted minimally invasive cochlear implant surgery

technical field

The utility model relates to the medical field, in particular to a tracking bracket used for a robot-assisted minimally invasive cochlear implantation operation.

Background technique

Cochlear implant surgery is the only effective way to improve the hearing of severely deaf and profoundly deaf patients. Due to the narrow operation area and complex anatomical structure, the doctor's experience is extremely required. The traditional cochlear implant surgery needs to grind the mastoid, fully expose the facial recess, and make a stoma on the cochlear bone wall to complete the electrode implantation. And the success of the operation is easily affected by the doctor's experience, so it is difficult to promote it to primary hospitals. At present, robotic technology is developing rapidly. Robots are used to complete tunnels and free doctors from surgical operations. Therefore, robotic-assisted minimally invasive cochlear implantation can be realized through technologies such as computer, image processing, and visual navigation. However, in the implementation process, additional tracking markers need to be added on the human head for spatial registration and visual navigation.

At present, the tracking markers used in the robot-assisted cochlear implant surgery generally have the following problems: one is a titanium nail directly nailed to the human skull, which brings additional trauma to the patient; the other It is a marker point pasted on the skull epidermis, but there is relative sliding between the scalp and the skull, which affects the accuracy. Therefore, the existing navigation markers cannot fully meet the requirements of minimally invasive cochlear implantation surgery assisted by robots.

Utility model content

The purpose of the utility model is to provide a tracking bracket for a minimally invasive cochlear implantation operation assisted by a robot, which ensures stable and safe connection with the human skull without adding additional trauma to the patient.

The technical scheme adopted by the utility model to solve its technical problems is:

A tracking bracket for minimally invasive cochlear implantation surgery assisted by a robot, comprising: a dental tray (1), a connecting rod (2) and a navigation bracket (3).

According to the utility model, the lower end of the connecting rod (2) is connected with the tooth tray (1); the navigation bracket (3) is installed on the upper part of the connecting rod (2).

According to the utility model, the dental tray (1) is composed of a dental socket (11) and a bracket installation groove (12); the dental socket (11) is a concave groove into which a dental silicone rubber impression material can be placed. The shape conforms to the U-shaped structure of the maxillary teeth of the human body; the bracket installation slot (12) is fixedly connected in front of the tooth slot (11).

According to the utility model, the connecting rod (2) is composed of an upper adjustment rod (21), a connecting rod (22) and a lower adjustment rod (23); the upper parts of the upper adjustment rod (21) and the lower adjustment rod (23) are evenly opened There are screw holes for installation and adjustment; the upper plane of the upper adjustment rod (21) forms an included angle of 30° with respect to the upper plane of the lower adjustment rod (22).

According to the utility model, the dental tray (1) and the navigation bracket (3) can be respectively fixed on the upper adjusting rod (21) and the lower adjusting rod (23), and can be slidably adjusted along the respective axial directions and fixed by screws.

According to the utility model, the navigation support (3) is composed of a bottom support (31), a tracking mark (32) and a fixing screw (33); wherein the fixing screw (33) on the bottom support is installed at four vertices of an asymmetric quadrilateral , the tracking marks (32) are mounted on the respective fixing screws (33)

The beneficial effects of the utility model are as follows: the size of the mouthpiece can be customized to suit the maxillary features of different patients; the fixation of the teeth and the overall tracking bracket can be realized through the silicone rubber impression material, without additional trauma; the tracking bracket is light and simple, and easy to operate. Before disinfection and use; the size of the structure is adjustable, easy to operate, which is beneficial to improve the precision and success rate of minimally invasive cochlear implant surgery assisted by robots.
