ORBITAL FLOOR IMPLANT
20220202575 · 2022-06-30 ·

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.

METHOD FOR PRODUCING MICROPARTICLES

The present invention provides a method for producing microparticles in which a porous micromold is degassed such that a precursor solution is quickly loaded into the micromold through the suction force of the micromold regardless of the viscosity and wettability of the precursor solution.

HOT STAMPING APPARATUS AND HOT STAMPING METHOD
20220169069 · 2022-06-02 · ·

A hot stamping apparatus and a hot stamping method are for collectively decorating a plurality of decoration objects using a decorative sheet. In a hot stamping apparatus, an upper chamber and a lower chamber are partitioned by a partition sheet and pressing bodies, so that decorative sheet pieces can be used instead of a decorative sheet having a large area. Then, by using the decorative sheet pieces, local thermal deformation can be prevented. A usage amount of the decorative sheet can be reduced, and three-dimensional decoration can be implemented as needed on a portion requiring decoration.
