A porous material and preparation method thereof is provided. The material includes a material body. The body consists of pore cavities classified according to pore size of material and cavity walls surrounding to form the pore cavities. The lower-level pore cavities are arranged on the cavity walls of the upper-level pore cavities framed by surrounding a three-dimensional space. All the pore cavities are interconnected. The preparation method is: mixing raw powders with pore-forming agent for the smallest-level pore cavities of porous material to formulate slurry; uniformly filling the slurry into polymer material support to form green body and get dried and smashed to obtain mixed grains; uniformly mixing the mixed grains with pore-forming agent for upper-level pore cavities greater than the smallest-level pore cavities of porous material to make compact green body; performing vacuum sintering; performing the conventional follow-up treatment according to the raw materials process of porous material.

Disclosed are a regenerative medical material for promoting the repair of soft and hard tissues, a preparation method therefor, and the use thereof. The regenerative medical material has a three-dimensional network structure and is a composite material composed of inorganics and organics, wherein the mass ratio of the inorganics to the organics is 2:1-4:1. Based on the total mass of the inorganics, the inorganics contain 12-38% SiO.sub.2, 3-5% Na.sub.2O, 15-29% CaO, 10-32.5% P.sub.2O.sub.5, 1-5% inositol hexaphosphate, 1-5% cyclohexanhexol phosphate, and the balance of impurities, with the content of impurities being less than 0.5%.

Systems, instruments, methods, and compositions are described involving removing a portion of the epidermis within a donor site on a subject, and harvesting dermal plugs within the donor site. An injectable filler is formed by mincing the dermal plugs. The injectable filler is configured for injecting into a recipient site on the subject.

An implantable mesh including demineralized bone fibers mechanically entangled into a biodegradable or permanent implantable mesh is provided. A method of preparing the implantable mesh is also provided. The method of preparing the implantable mesh includes mechanically entangling demineralized bone fibers with non-bone fibers to form the implantable mesh. The mechanical entanglement of the bone fibers into the implantable mesh is achieved by applying needle punching with barbed needles, spun lacing, entanglement with water jets or air jets or ultrasonic entanglement with ultrasonic waves. A method of implanting an implantable mesh at a target bone tissue site is also provided.
