Abstract

The invention discloses an electromagnetic / resistance bimodal imaging device for guiding hip replacement. The device comprises an electromagnetic / resistance bimodal sensor module, the electromagnetic / resistance bimodal sensor module comprises a circular sleeve sleeving hip joint of the human body, an electromagnetic chromatography imaging sensor and a resistance chromatography imaging sensor, thecircular sleeve comprises an inner conductor ring and an outer shielding ring, an input end of the electromagnetic chromatography imaging sensor is connected with an output end of a first multichannelgating switch, an output end of the electromagnetic chromatography imaging sensor is connected with a first input end of a signal acquisition and treatment module, an input end of the resistance chromatography imaging sensor is connected with an output end of a second multichannel gating switch, and an output end of the resistance chromatography imaging sensor is connected with a second input endof the signal acquisition and treatment module. The electromagnetic / resistance bimodal imaging device for guiding hip replacement has the characteristics of simple structure, high response speed andgood timeliness.

Description

technical field [0001] The invention relates to the technical field of medical electronics, in particular to an electromagnetic / resistance dual-mode imaging device for guiding hip replacement revision. Background technique [0002] Since the first successful artificial hip replacement in the 1960s, hip replacement has become one of the most important surgical operations in the 20th century. The joint stays in the body for a long time, and the postoperative activity is relatively large, so more and more patients need revision surgery. According to statistics, about 10% of artificial hip replacements require artificial hip revision. [0003] Revision hip arthroplasty is not simply a process of replacing the old prosthesis with a new one, but a much more complicated operation than primary hip arthroplasty. Compared with primary hip arthroplasty, the revision operation time is longer and the blood loss is more serious. There are many, and the incidence of complications is also...
