Benefits of technology

This new type of implant allows patients who have had an infected arthritic knee or hip joint to take care they don't get sick from having their pain out too much by giving them medicine everyday instead of constantly taking medication over several days during recovery periods. It also includes a special chamber that holds some liquid called tampons filled into it when needed. These liquids release gradually through holes on top of the device itself allowing blood vessels inside to help fight off any bacteria getting trapped behind.

Problems solved by technology

The technical problem addressed in this patented solution is how to prevent contamination from overuse injuries caused during orthopedic procedures while maintaining good stability between different parts of the patient's anatomy.

Abstract

The invention relates to a medical apparatus, in particular to a prosthesis component for drug-release treatment of postoperative infection of joint. The prosthesis component comprises a joint prosthesis and a joint stem prosthesis, wherein medicine accommodating cavities are formed in the joint prosthesis and the joint stem prosthesis. The joint prosthesis, compared with a conventional spacer, has a joint prosthesis moving function, and the joint prosthesis can keep the stability of joints while guaranteeing the daily activities of the joints; meanwhile, the interior of the joint prosthesis is subjected to hollow design and is provided with the medicine accommodating cavity for accommodating medicines; and the medicines, after being injected, are released in a sustained mode, so that continuous administration to an infected articular cavity is achieved, and subsequently, the infection is cured; and meanwhile, the problem that treatment becomes invalid due to the generation of a great amount of debris caused by fractures in the conventional spacer is avoided.
