    摘要: In a general aspect, an apparatus for washing biological material is provided which includes an outer sleeve, and an inner sleeve disposed within the outer sleeve. The outer sleeve has an open end for receiving the biological material, and an opposed closed end. The inner sleeve is detachably and slidably positioned within the outer sleeve, and includes a first port for receiving and dispensing washing liquid, a second port defining a liquid flow path between an interior of the inner sleeve and an interior of the outer sleeve, and a filter disposed in the second port. The filter allows passage of washing liquid but not passage of the biological material therethrough. A chamber, formed between the filter and the closed end of the outer sleeve, is configured to permit flow of washing liquid via the filter while retaining the biological material therein.

    摘要: A bone awl is provided for preparing a bone for implantation with a screw. The awl includes a shaft having a first end and a second end opposed to the first end. A handle is fixed to the first end, and an extension extends from the second end. The extension includes a first cutting portion configured to form a hole in bone and a second cutting portion configured to form an internal screw thread in the bone along the surface of the hole. The awl also includes an axial through passage that extends from the handle to the first cutting portion and is dimensioned to receive a Kirshner pin therein.

    摘要: The present invention provides a process for producing porous polymer materials. In the present invention, a polymer material and a soluble material are mixed in their solid states. The surface of the polymer material is partially dissolved and fused by introducing a solvent. The present invention makes use of a pressure difference while introducing a non-solvent into the polymer material to solidify and resolve the solved polymer material. Then, a substantial amount of water is used to wash the inside soluble material out. Therefore, the porous polymer materials with high porosity and interconnecting pores inside the materials are produced massively and rapidly.

    摘要: A biphasic cement of &agr;-TCP/HAP is primarily composed of 30-60 wt % &agr;-tricalcium phosphate (Ca3(PO4)2, &agr;-TCP) and 40-70 wt % of hydroxyapatite (Ca10(PO4)6(OH)2, HAP). The biphasic cement of &agr;-TCP/HAP of the present invention is superior since it can set rapidly while soaking in a water solution. The present invention also provides a process for preparing the biphasic cement of &agr;-TCP/HAP, in which the composition of the biphasic cement of &agr;-TCP/HAP can be controlled.
