Device for achieving intraoperative evaluation of ophthalmic surgery

Abstract

The invention relates to a device for achieving intraoperative evaluation of an ophthalmic surgery. The device comprises a base, a mechanical arm, a display screen, a probe box body, a demodulation module and a foot pressing operation box body, a probe module moving along a sliding rail is installed in the probe box body, focus information collection is conducted on eyes by a fretting motor and afocus motor driving probe module which are controlled by the foot pressing operation box body, a broadband light source, an optical fiber coupling device, two polarization controllers and a referencearm are fixedly installed in an cavity of the mechanical arm, the broadband light source is divided into two beams after the broadband light source passes through the optical fiber coupling device, one signal beam enters the probe module passing through the polarization controllers to form a sampling arm for collecting eye information, the other reference beam enters the reference arm passing through the polarization controllers, an interference beam is formed after the two beams return, and the interference beam enters the demodulation module to form an optical coherence tomography system tobe displayed on the display screen. The device has the advantages of being stable in polarization state and signal-to-noise ratio and flexible to operate, and the device can be adopted as objective evaluation bases of the ophthalmic surgery and used as a surgical guiding device.

Description

technical field [0001] The invention belongs to the technical field of ophthalmic medical equipment, and relates to a device for realizing intraoperative evaluation in ophthalmic surgery. Background technique [0002] The eye is the most important sensory organ of the human body. In recent years, with the popularization of electronic equipment, the high incidence of eye diseases has become one of the key topics that people are most concerned about. Overuse or improper use of the eyes can cause eye damage. In severe cases, ophthalmic surgery is required for necessary treatment, such as corneal LASIK surgery, intraocular lens surgery, sclera reinforcement surgery, and retinal surgery. The patient first receives a preoperative examination, and the doctor formulates an operation plan based on the examination, calculates the location and scope of the operation, and finally conducts postoperative observation to verify the operation result. In this process, it is impossible to eva...

AI Technical Summary

Problems solved by technology

The device integrates the OCT probe module with the spectacle frame. Although the operator's hands are freed, the relative position of the operator's head and the subject's eyes needs to be kept fixed, which is still not suitable for surgical process evaluation.

At the same time, the device also has the problem of low signal-to-noise ratio due to random shaking of the optical fiber
