  • Publication number: 20200100376
    Abstract: Embodiments disclosed herein provide an apparatus to enable smooth and safe assembly of functional modules to computer chassis. The apparatus includes a chassis and a pair of racks mounted to the chassis. Each rack has a plurality of gear teeth formed thereon. A module having a housing is slidably coupled to the chassis and disposed between the pair of racks. A pair of gear pinions are rotatably mounted to the housing and meshed to the gear teeth of one of the racks. A damping member is coupled between each gear pinion and the housing. A sliding movement of the housing relative to the chassis rotates the pair of gear pinions to roll over along the gear teeth. During the sliding movement of the housing, the damping member exerts a resistance force against the housing, to reduce the movement speed of the housing.

  • Publication number: 20190231926
    Abstract: A bone graft composition promoting osteogenic capacity is provided. The bone graft composition includes an osteoinductive component including statins and a biodegradable polymer and an osteoconductive matrix including a biodegradable calcium phosphate ceramic, wherein the amount of the calcium phosphate ceramic is about 70 to 95 wt % based on the total weight of the bone graft composition. The bone graft composition can achieve the optimal release control characteristics of the statins in the osteoinductive component.

  • Patent number: 8962037
    Abstract: The present invention discloses a method of manufacturing pure dicalcium phosphate ceramics or dicalcium phosphate/hydroxyapaite (HA) biphasic ceramics for medical applications in hard tissue areas to be used as implant materials. These ceramic implant materials are in granular form or in block form, and are prepared by using an acidic phosphate compound, a basic calcium phosphate compound comprising HA, and water. The dicalcium phosphate ceramic comprises either dicalcium phosphate dihydrate (CaHPO4.2H2O, DCPD) or dicalcium anhydrous (CaHPO4, DCPA). Wherein, when the acidic phosphate compound is provided in an amount stoichiometrically equal to or in excess relative to the basic calcium phosphate compound, a reaction product is the DCPD or DCPA ceramic; when the acidic phosphate compound is provided in the amount stoichiometrically less than the basic calcium phosphate compound, the reaction product is the DCPD/HA or DCPA/HA biphasic ceramic.

  • Patent number: 8834470
    Abstract: A bone repairing kit including a drilling device, a pushing device, a clamping member and a hole saw. An end of a tube body of the drilling device is a knife portion. When the tube body rotates with respect to a femur, a bone column is cut by the knife portion and located in the tube body. The pushing device includes a hollow tube and a push bar. The hollow tube is for receiving the tube body. The push bar is for touching and pushing the bone column in the tube body. The clamping member is for clamping the bone column. The hole saw includes a receiving body and cutting knives. The receiving body has a recess for receiving an end of the bone column. The cutting knives surrounding on an inner wall of the recess are for cutting an edge of the end of the bone column.

  • Patent number: 8414930
    Abstract: The present invention discloses a surgical cement and a manufacturing method thereof. The surgical cement comprises a cementing component selected form the group of a basic calcium phosphate consisting of tetracalcium phosphate, alpha-tricalcium phosphate, decomposed hydroxyapatite, or a combination thereof; a setting reagent selected form the group of an acidic calcium citrate consisting of monocalcium citrate, dicalcium citrate, or a combination thereof; and water; wherein a weight ratio of the cementing component and the setting reagent ranges from about 1:1 to about 8:1. The surgical cement is bioresorbable and bioactive and is useful in orthopedic, maxillofacial and dental applications. In addition, the surgical cement of this invention has a good flow character and a relatively short setting time.
