Device, Tool and System for Minimally Invasive Orbital Floor Fracture Implantation

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides a minimally invasive implant device, tool, and system specifically designed to treat fractures of the orbital floor (the bone beneath the eye). The implant is specially engineered to be foldable for easy insertion and then can be unfolded and extended inside the body to provide strong support for the fractured bone. It is applied using a dedicated surgical tool through the nasal cavity, reducing the need for large external incisions around the eye. The system includes the implant, the specialized tool for insertion, and a method for using them safely and effectively.

Use CasesContent extracted from patent full text and abstract with AI.

• Surgical treatment of orbital floor (blowout) fractures resulting from trauma, such as car accidents, sports injuries, or assaults.
• Orbital floor reconstruction to correct symptoms like enophthalmos (sunken eye) or double vision caused by the herniation of orbital tissues into the sinus cavity.
• Minimally invasive endonasal (via nasal cavity) repair procedures for orbital bone injuries, avoiding traditional incisions through the eyelid or surrounding skin.
• Providing personalized implants that can be adjusted during surgery to match the patient's unique anatomy.

BenefitsContent extracted from patent full text and abstract with AI.

• Greatly reduces invasiveness of orbital floor fracture repair compared to traditional surgery, leading to less tissue damage, reduced scarring, and potentially faster recovery times.
• Implant can be inserted in a compact, folded state and then unfolded and extended once inside, allowing coverage of a wider area and easier placement even through small access points.
• Decreases risk to critical structures such as the eyeball and optic nerve by avoiding the need to manipulate or displace the eye during surgery.
• Personalized fit is possible during surgery, as the implant can be plastically extended to match the individual patient's bone structure.
• Systematic approach: a dedicated insertion tool and implant design enable precise, controlled, and safer deployment with good surgical visibility (via endoscope or similar).

Patent Abstract

The invention refers to an implant device (10) for treating an orbital floor fracture. The implant device (10) is foldable in a first direction between a folded state and an unfolded state and is plastically extendible in a second direction from an unextended state to an extended state. In the extended state, the implant device (10) has an extension in the second direction that is longer than a length in the unextended state and equal to or greater than an aperture distance of a human maxillary sinus in an anterior-posterior direction. The invention further refers to a related implantation tool and a related implantation system for treating orbital blow fractures and to a corresponding implantation method.
