Abstract

A method of tracking medical surgical instruments using encoded radio frequency tags incorporated in labels which are affixed to each instrument. A database of instruments is maintained at a hospital which may contain identification and status information for each instrument. A standard data format is used in the tags to provide a universal inventory system for medical institutions, medical instrument manufacturers and service companies. The tags may be instantly identified by a microprocessor system having a radio frequency scanner. The scanner may optionally write data to a radio frequency tag. A method of accounting for instruments used in a surgical procedure by performing an electronic radio frequency scanning inventory before a procedure and again before a surgical cavity is closed.

Claims

1. A medical surgical instrument having a radio frequency tag affixed thereto wherein said radio frequency tag caries data which identifies said medical surgical instrument and wherein said data is readable by a radio frequency scanner.

2. A medical surgical instrument according to claim 1 wherein said radio frequency tag comprises a label wherein said label comprises an outside layer and an adhesive layer.

3. A medical surgical instrument according to claim 2 wherein said label and said radio frequency tag have a combined thickness of about 0.006 inches.

4. A method of performing a medical surgical procedure and maintaining an inventory of the medical instruments used during the surgical procedure comprising:

providing a plurality of surgical instruments each of which has a radio frequency identification tag affixed thereto;

scanning each of said instruments prior to beginning the surgical procedure to obtain an inventory;

performing the surgery by using the instruments that have been scanned and inventoried;

scanning each of said instruments prior to closing any surgical cavity to accertain that all instruments have been accounted for; and

closing any surgical cavity.

5. A method of accounting for surgical instruments used in a medical surgical procedure comprising:

providing a plurality of surgical instruments each of which has a radio frequency identification tag affixed thereto;

performing the surgery using said surgical instruments;

directing a scanning device toward any surgical cavity;

detecting the presence of any surgical instrument in the area of any surgical cavity by operating said scanning device.

6. A data format for organizing data within a memory space of a radio frequency tag wherein said data format requires a unique code to fill a particular memory space wherein said unique code is a registered identification code associated with a particular medical instrument manufacturer.

7. The data format according to claim 6 further comprising additional blocks of memory allocated for coded data which are associated with an instrument description, an instruments use, an instruments part number an instrument serial number and an instrument user identification code.

8. A method of providing medical instrument manufacturers with unique identification codes for use in medical instruments having radio frequency tags comprising:

providing a medical instrument manufacturers registration service wherein said service comprises;

maintaining a database of codes associated with each registered medical instrument manufacturer;

distributing a unique identification code to each manufacturer who requests to be registered;

suppling a list of registered manufacturers and their corresponding identification codes to hospitals and any other end user of radio frequency tagged inventory systems who may request said list.

9. A computer program which is capable of controlling a microprocessor system wherein said microprocessor system is in communication with a database having data which correlates a list of any number of surgical procedures to a set of surgical instruments which is required to perform said surgical procedure and wherein said surgical instruments are identified within said database by an identification code associated which is associated with an identification code contained in a radio frequency tag attached to or associated to each instrument and wherein said microprocessor system is also in electronic communication with a radio frequency scanner and wherein said computer program is capable of causing the microprocessor system to perform the steps of:

presenting a list of surgical procedures to a user;

waiting for a user to choose at least one surgical procedure from said list;

allowing a user to enter an input to identify at least one chosen procedure;

prompting a user to scan a set of tagged medical instruments with a radio frequency scanner;

reading identification codes for each instrument scanned from a radio frequency scanner;

comparing the data of scanned instruments to data of instruments required for the selected surgical procedure;

alerting the user if all of the correct instruments are present in the scanned set;

alerting the user if all of the correct instruments are not present in the scanned set and providing the user with a list of instruments which are not present that are required for the selected procedure.
