Problems solved by technology

[0003] In the prior art, the positioning of the cornea is to check the corneal curvature and corneal topography before the corneal transplantation operation to obtain the position information of the cornea. Since the corneal positioning ring needs to be placed to assist the positioning in the prior art, this positioning The steps are relatively cumbersome, and the probability of system error is relatively high

Abstract

The invention discloses a system and method for automatically positioning cornea, relates to the field of medical instruments and aims at improving accuracy of cornea positioning and lowering labor amount. The system comprises a mechanical arm component, an image recognition system, a background component, a calculation positioning system, a main control system and a mechanical control system, the background component is arranged oppositely to the image recognition system, the calculation positioning system is connected with the image recognition system, the mechanical control system is connected with the main control system, electrically connected with the mechanical arm component and used for controlling the mechanical arm component to move a cornea packaging body packaged with cornea to space between the image recognition system and the background component, and the main control system is electrically connected with the image recognition system and the calculation positioning system and used for controlling the same to acquire images formed by the cornea packaging body under action of background light and analytically calculating the images acquired by the image recognition system to acquire position information of the cornea. The system is applied to cornea positioning.

Description

Technical field [0001] The invention relates to the field of medical equipment, and in particular to a cornea automatic positioning system and method. Background technique [0002] Corneal disease is the second cause of blindness worldwide, and it is increasing at a rate of 1.5-2 million cases per year. Corneal transplantation is currently the only effective way to treat corneal blindness, and the sources of corneal transplant materials are mainly corneal donations and corneal substitutes, such as acellular corneal stroma. Although the success rate of corneal transplantation is quite high and the rejection rate is very low, the recovery of eye vision after corneal transplantation is very unsatisfactory. The main manifestation is irregular astigmatism, because corneal transplantation cannot overcome the existence of irregular astigmatism. The current problem in corneal transplantation is how to locate the cornea. [0003] In the prior art, the positioning of the cornea is to check...
