Artificial joint prosthesis with biologically activated surface

Rectangular waveguide microwave plasma source generating device

The invention discloses a rectangular waveguide microwave plasma source generating device, which comprises a rectangular waveguide resonance cavity, a gas carrying module, a regulation module, a light path module, a circuit control system, a maintaining gas control system and a sample gas carrying control system. The rectangular waveguide microwave plasma source generating device provided by the invention has the advantages that the excitation energy can be from 200W to thousands of watts, under the effect of the circuit control system, the microwave energy forms the plasma by the carrier gas ionization in the resonance cavity, the plasma contains sample spectrum information, the sample spectrum information can be transmitted out through the light path module, and the goal of analyzing substances in medium gas is achieved.

Artificial joint prosthesis with biologically activated surface

The invention belongs to the technical field of surgical implants and relates to an artificial joint prosthesis with biologically activated surface. The biological activation layer formed on the surface of the artificial joint prosthesis has good biocompatibility and bioactivity and forms natural chemical bonding with the bone tissues, thus improving the bond strength between the prosthesis and the bone tissues, ensuring the stress transfer to be more reasonable and reducing the negative effect of stress shielding. The biological activation layer on the surface of the artificial joint prosthesis is formed by chemical reaction and forms chemical bonding with the matrix, therefore, the problem that the biological activation layer on the surface sheds is avoided, thus ensuring the postoperative long-term effect of the prosthesis. The artificial joint prosthesis is biologically fixed; therefore, wear particles produced when bone cement is adopted for fixation are avoided, thus reducing the ...
