摘要:
A method is designed to control the working time, setting time and the semi-solidification time of a gypsum composition in a bone restoration operation. The method involves a preparation of the gypsum composition by mixing an orthopedic gypsum and an aqueous solution in a weight ratio to form a semisolid substance which is to be injected into a patient under treatment. The aqueous solution contains serum, blood plasma, or whole blood, which is preferably taken from the patient under treatment.
摘要:
An orthopedic implant has a porous surface with a plurality of pores, some of which are provided with a pores-within-a-pore structure. The pores-within-a-pore structure has a pore opening ranging in size between 10 and 800 microns. The present invention also discloses a process for making an orthopedic implant which is provided in the surface thereof with a pores-within-a-pore porous structure.
摘要:
The present invention relates to a method of using a computer to collect chemical signals directly from a chemical sensor. This method first transforms analog chemical signals received from the chemical sensor into analog electronic signals in a transforming circuit in cooperation with control computer programs executed in the computer, then uses an Analog-to-Digital converter, which connects the transforming circuit with the computer, to transform the analog electronic signals into digital signals; and finally transfers the digital signals to the computer.

摘要:
A method of using a plaster of Paris as an orthopedic filling material prepared by mixing 15-80% by weight of calcium sulfate half-hydrate and 85-20% by weight of water, an aqueous solution, an aqueous dispersion, or an aqueous suspension; and stirring the resulting mixture into a paste having a viscosity in the range of 20 and 75 poises. The paste is injected into a cavity of a bone or a vertebra to be reinforced. The injected paste becomes hard in the cavity, and eventually will be absorbed by the patient.
摘要:
An amplifier circuit includes a transistor having a control terminal, a first and a second terminal, a signal input terminal coupled to the control terminal of the transistor, as well as a transformer with a primary side and a secondary side, the primary side of which is coupled to the first or second terminal of the transistor. The amplifier circuit further includes a signal output terminal coupled to the secondary side of the transformer. Hereby it is possible to provide an amplifier circuit with a better characteristic as opposed to a conventional amplifier circuit, which is further easy to manufacture.

A spinal fixation and retrieval device comprises a retrieval main body, two side pieces, and a fastening device for fastening substantially symmetrically the two side pieces with two sides of the retrieval main body. The two side pieces are substantially smaller in thickness than the retrieval main body.
摘要:
A spinal fixation and retrieval device includes a bone plate and a plurality of screws. The bone plate has a plurality of slot holes via which the screws are fastened onto vertebrae under treatment. The screws have a head, a neck, and a threaded stem in sequence. At least one of the slot holes of the bone plate is a long slot hole having a dimension so that the neck of the screw is restricted in the lateral direction and is able to move in the longitudinal direction of the long slot hole.
