An orbital implant adapted for attachment to the very thin bone at the orbit rim (502), such as the zygomatic and frontal bone margin at the supero-lateral aspect (501) of the orbit (503), for the attachment of an eye prosthesis directly to distal ends of inwardly convergently orientated transdermal abutments. The orbital implant has a baseplate (100) having an orbit radius curvature and an orbit rim curvature and a plurality of microfixation apertures therethrough and the plurality of transdermal abutments are located at an inner edge of the baseplate (100).

Embodiments of the present disclosure relate generally to a Sizer, Introducer, and Cutting Template Device. Embodiments find particular use as a sizer, introducer, and cutting template device for an orbital floor implant surgery. The disclosed device allows a surgeon or other practitioner to use a single component for sizing, introducing, and cutting a template for an orbital floor implant.

The invention relates to an implant (1) for the treatment of bone, in particular for covering defects or drill holes or for the reconstruction of bone defects or malformations. This comprises at least one frame structure (2) and at least one adaptation area (3). The edge of the implant (4) is thereby partially, but not continuously, formed by the frame structures (2), which are located outside the adaptation area (3).

A filament or printing material placed in a syringe for 3D printing comprising polymers, proteins, and/or functional particles and materials is provided. Methods of treating a bone defect in a subject in need thereof comprising using a handheld 3D printer to apply a filament or the printing material placed in a syringe to the bone defect of the subject are also provided. Methods of fixing or gluing natural or synthetic bone grafts using a handheld 3D printer to apply a filament or the printing material placed in a syringe over and around the defect or at the interface of a flap and the bone. Methods of printing a graft cage for retaining bone grafts and/or bone graft substitute in its desired location during healing for treatment of critical-sized segmental defects in long bones are provided.

A system for manufacturing and using an implant for correcting a defect of a bone structure is described. In some examples, the implant includes a first surface comprising a shape configured to interface with a surface of the bone structure. In some examples, the implant includes a second surface opposite the first surface and substantially conformal to the shape of the first surface, the second surface comprising three or more point features on the second surface, wherein the three or more point features comprise a first point feature, a second point feature, and a third point feature that form nodes of a triangle, wherein each of the three or more point features are recessed below the second surface.

A surgical device for retracting tissue of a subject while offering lighting and suction means integrated into the same device. This device is useful in many different surgical procedures, including those requiring precise tissue retraction in small openings of a subject, such as facial orbital fracture repair.

A method of forming a patient-specific-bone-graft cage based on a patient-specific bone graft cage computer model that is based on a contour of a surface of the bone defining a void, and/or a patient-specific-bone-graft cage that includes a plurality of apertures, that terminate at a location between a front surface and a back surface of the patient-specific-bone-graft cage, for receipt of bone graft material. The patient-specific-bone-graft cage can construct an essential portion (including complex thin anatomical structures) of or substantially the entirety of the mid-face region (e.g., to fill a void in a damaged orbital region), which enables an improved structure reproduction and simplification for the surgeon. For example, the patient-specific-bone-graft cage may be formed based on the contour of the periphery defining the void in the damaged region, and require less modification by a surgeon compared to graft cages formed only by mirroring techniques or normalized models.

Embodiments of the invention described herein thus provide systems and methods for providing improved surgical implants. Embodiments of the implants may include a thin porous sheet formed on a mandrel. The porous sheet that is formed has an interconnected pore structure that may be compressed by a heat compression mold without losing porosity. Additional membrane materials or other layer materials may be applied to one of the face surfaces of the porous sheet or to one of the edges of the porous sheet. For example, a solid membrane surface may be compressed, bonded, welded, or secured a surface face or an edge of the porous sheet. The solid membrane may be compressed or laminated to the upper surface, lower surface, or both. The solid membrane may be welded to at least one edge of the porous sheet (by, for example, being butt welded, thermally bonded, or heat compressed to the at least one edge).

Embodiments of the present disclosure relate generally to an orbital floor implant (10). One embodiment provides an implant with a first surface that is a fully porous, bone-side layer (16) and a second surface that is a non-porous, orbital content-side layer (18). The implant material itself may be polymeric material throughout, without the need for an embedded mesh or other support matrix. The implant is provided in a pre-shaped configuration and is of a material that allows it to be bent for shaping purposes. An extending tab (12) with eyelet portion/opening (14) can enhance securement options to a patient's bone.

A filament or printing material placed in a syringe for 3D printing comprising polymers, proteins, and/or functional particles and materials is provided. Methods of treating a bone defect in a subject in need thereof comprising using a handheld 3D printer to apply a filament or the printing material placed in a syringe to the bone defect of the subject are also provided. Methods of fixing or gluing natural or synthetic bone grafts using a handheld 3D printer to apply a filament or the printing material placed in a syringe over and around the defect or at the interface of a flap and the bone. Methods of printing a graft cage for retaining bone grafts and/or bone graft substitiute in its desired location during healing for treatment of critical-sized segmental defects in long bones are provided.
