Description

Technical Field

[0001] The present invention relates to the field of ophthalmic plastic surgery, and in particular to a multi-degree precise improvement system for ptosis based on Whitworth's ligament. Background Art

[0002] With the development of society and the improvement of people's living standards, the cosmetic surgery industry has gradually entered the public eye. Whether it's to correct congenital deformities or enhance appearance, plastic surgery has become a part of many people's lives. This article will delve into several key medical cosmetic surgery departments, including plastic surgery, cosmetic surgery, dermatology, oral and maxillofacial surgery, otolaryngology, and ophthalmology, as well as the importance of psychological counseling within these departments. Plastic surgery is one of the foundational disciplines in cosmetic surgery, focusing on restoring and reconstructing the body's function and appearance. Plastic surgeons commonly treat conditions such as congenital deformities, post-traumatic reconstruction, and repair after tumor resection. Ophthalmology, in cosmetic surgery, primarily involves cosmetic procedures involving the eyes, such as double eyelid surgery and eye bag removal. Double eyelid surgery is one of the most common eye plastic surgery procedures, creating natural-looking double eyelids and enhancing the three-dimensional appearance of the eyes. Eye bag removal: With aging, the appearance of eye bags can diminish the youthfulness of the face. Ophthalmologists surgically remove excess fat and skin to brighten the eyes. When performing ophthalmologic plastic surgery, ophthalmologists must pay special attention to the structure and function of the eye to ensure that the surgical results are natural and safe.

[0003] Traditional ptosis correction surgery relies too much on shortened levator palpebrae superioris muscles, resulting in unnatural dynamic eyelid movement after surgery. The Whitworth ligament, a key suspension structure of the levator palpebrae superioris muscle system, has not yet formed a standardized grading system for its anatomical positioning and tension regulation. In addition, the technology lacks differentiated ligament treatment plans for mild, moderate and severe cases, making it difficult to achieve personalized treatment.

[0004] To this end, we propose a multi-level precise improvement system for ptosis based on Whitworth's ligament. Summary of the Invention

[0005] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a multi-degree precise improvement system for ptosis based on Whitworth ligament.

[0006] In order to achieve the above-mentioned objectives, the present invention adopts the following technical solutions: a multi-degree precise improvement system for ptosis based on Whitworth ligament, including a diagnostic evaluation module, a preoperative simulation module, a surgical instrument module, a surgical plan module, a postoperative tracking module and a comprehensive management module; the diagnostic evaluation module includes a multi-dimensional data acquisition unit, a ptosis degree intelligent grading unit and a ligament status analysis unit; the multi-dimensional data acquisition unit is used to collect data from an eyelid motion trajectory capture device, a muscle strength detection probe and a palpebral fissure height measuring instrument; the ptosis degree intelligent grading unit is based on a dynamic symmetry analysis algorithm of Hering's law, and intelligently grades the collected data to determine the severity of ptosis; the ligament status analysis unit is used to collect data from a Whitworth ligament tension measuring instrument and an elastic modulus detection component to evaluate the health status and elastic properties of the Whitworth ligament.

[0007] Preferably, the preoperative simulation module includes a three-dimensional anatomical modeling unit, a mechanical dynamic simulation unit and an effect prediction unit. The three-dimensional anatomical modeling unit integrates a stereoscopic imaging system of the Whitworth ligament and the levator palpebrae superioris muscle complex to construct an accurate three-dimensional model of the patient's upper eyelid tissue. The mechanical dynamic simulation unit is used to predict the eyelid movement trajectory of different lifting angles. The effect prediction unit generates a preview image of the surgical effect based on the personalized aesthetic evaluation matrix of the patient's facial features and the patient's specific situation, providing an intuitive reference for the doctor.

[0008] Preferably, the surgical instrument module includes a minimally invasive incision locator, a special instrument for ligament adjustment and a biological fixation device. The minimally invasive incision locator is used for the Whitworth ligament surface projection positioning laser guide device and the minimally invasive incision auxiliary marking component. The special instrument for ligament adjustment adopts an adjustable Whitworth ligament folding device with a 0.5mm precision adjustment mechanism. The biological fixation device is used for temperature-sensitive collagen ligament fixing clamps and ligament repair materials to ensure precise adjustment and stable fixation of the ligament during surgery.

[0009] Preferably, the surgical plan module includes a mild correction unit, a moderate correction unit and a severe correction unit. The mild correction unit adopts the Whitworth ligament advancement folding procedure library and sets 8 folding angle templates. The moderate correction unit is based on the ligament tension balance adjustment algorithm and provides 12 ligament folding and reinforcement plans to meet the needs of patients with moderate ptosis. The severe correction unit integrates ligament reconstruction and muscle strength enhancement technology, and designs a complex surgical process including ligament transplant material selection and pretreatment and muscle strength enhancement device configuration to ensure that patients with severe ptosis can also obtain satisfactory surgical results.

[0010] Preferably, the postoperative tracking module includes a dynamic recovery evaluation unit, a complication prevention unit and an effect comparison unit. The dynamic recovery evaluation unit is used for an intelligent eyelid closure monitoring patch and an eyelid movement trajectory capture device to monitor the patient's postoperative eyelid recovery and movement trajectory in real time. The complication prevention unit is a rehabilitation training plan generator based on the ligament healing curve to predict possible complication risks and provide corresponding preventive measures. The effect comparison unit evaluates the success rate of the operation and the patient's satisfaction by comparing the preoperative simulation effect and the actual postoperative effect.

[0011] Preferably, the comprehensive management module includes a multi-center data integration unit, a quality control standard unit, and a technical training unit. The multi-center data integration unit is based on the Whitworth ligament anatomical variation database, which is used to collect and analyze anatomical variation data of the Whitworth ligament worldwide, providing a scientific basis for the continuous optimization of the system. The quality control standard unit is based on the efficacy evaluation matrix of 500 clinical data to formulate surgical quality and safety control standards to ensure the stability and reliability of the system. The technical training unit adopts the Whitworth ligament surgery simulation training system, which includes a bleeding volume control module, a fine operation module, and a complication handling module to provide doctors with comprehensive technical training and practical guidance. The bleeding volume control module simulates bleeding during surgery to train doctors to quickly identify and effectively control bleeding points during surgery, thereby improving the safety and efficiency of surgery. The fine operation module focuses on the fine operation of surgical instruments and the precise execution of surgical steps. Through simulation training, doctors can master various surgical techniques and reduce errors and injuries during surgery.
