Multiplex system for the detection of surgical implements within the wound cavity
First Claim
1. A multiplex system for detecting surgical implements within a surgical cavity of a patient, comprising:
- a first system for electronically detecting surgical implements;
a second system for electronically detecting surgical implements, said second system being different from said first system; and
both said first system and said second system being used to inspect the surgical cavity for surgical implements.

Abstract
The present invention provides a multiplex system for identifying the presence of surgical sponges, metal instruments, and other implements in a surgical wound by employing a plurality of discrete sensing systems. At least two modalities of operation are chosen from a plurality of detection modalities, which can include: 1) magnetomechanically resonant marker tags; 2) “smart markers” or RFID markers; and 3) a system designed to detect metallic objects solely based upon their metal content, without need for a separate, affixed marker. The selected modes of operation can operate sequentially or simultaneously. Consequently, the use of such a multiplex system eliminates the possibility that surgical implements, non-metallic or metallic, will be left behind within a surgical cavity.

31. A multiplex system for detecting surgical implements within a surgical cavity of a patient, comprising:
-
a first system for electronically detecting surgical implements, said first system detecting a surgical implement by detecting a first radiofrequency marker associated with said surgical implement;
a second system for electronically detecting surgical implements, said second system either detecting a second radiofrequency marker of a different type than said first radiofrequency marker associated with said surgical implement or detecting metallic objects based upon their metal content; and
both said first system and said second system being used to inspect the surgical cavity for surgical implements. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38)
