Description

Technical Field

[0001] The present invention relates to the field of ophthalmic surgical instruments, and particularly to an anterior chamber maintenance and positioning device for ICL implantation surgery. Background Art

[0002] ICL (Implantable Collamer Lens) implantation surgery is a common refractive surgery for correcting high myopia, hyperopia and astigmatism. This surgery achieves vision correction by implanting a specially designed intraocular lens into the anterior chamber of the patient. During the surgery, the stability of the anterior chamber is crucial. The anterior chamber is a space filled with aqueous humor inside the eyeball, and its stability directly affects the smooth progress of the surgery and the postoperative effect. If the anterior chamber collapses during the surgery, it may lead to serious complications such as corneal endothelial damage, iris damage and even lens dislocation. In addition, the position and angle of the intraocular lens also need to be precisely adjusted to ensure the best visual effect.

[0003] Existing anterior chamber maintenance devices usually rely on manual operation, and there are problems such as complex operation and insufficient positioning accuracy. For example, traditional anterior chamber maintainers need to manually adjust the perfusion rate to maintain the anterior chamber pressure, which not only increases the complexity of the surgery, but also may cause fluctuations in the anterior chamber pressure and affect the surgical effect. In addition, the positioning of the intraocular lens usually relies on the doctor's experience and touch, lacking precise quantitative control and prone to positioning deviation. Therefore, there is an urgent need for a new type of anterior chamber maintenance and positioning device that can automatically maintain the anterior chamber pressure during the surgery and precisely adjust the position and angle of the intraocular lens, thereby improving the safety and success rate of the surgery.

[0004] Based on this, the present invention designs an anterior chamber maintenance and positioning device for ICL implantation surgery to solve the above problems. Summary of the Invention

A control system for an anterior chamber maintenance and positioning device used in ICL implantation surgery, characterized in that: The control module includes a sensor integration system, a feedback control mechanism and a user interface. The sensor integration system is responsible for receiving data from the pressure sensor and other sensors for implementing monitoring of the surgical process. The feedback control mechanism automatically adjusts the flow rate of the perfusion pump according to the sensor data to ensure precise control of the anterior chamber pressure. The user interface provides real-time surgical data and operation options for the doctor, and the doctor can manually adjust the perfusion and position adjustment parameters through the interface.
