Smart recognition apparatus and method
First Claim
1. A surgical instrument having a first connection part for connection to a second connection part of a generator, the generator adapted to apply energy to the surgical instrument and having an identifying circuit associated therewith responsive to modified light communicating through the first and second connection parts to identify the surgical instrument connected to the generator, the second connection part including a light supply and a light receptor wherein the light supply transmits a non-focused light beam to the first connection part and the light receptor receives the modified non-focused light beam from the first connection part, the surgical instrument comprising:
- a first optical coupling on the first connection part, the first optical coupling including a light modifier in the form of a diffuse surface which modifies the non-focused light beam received from the light supply of the second connection part, the diffuse surface including responsive medium having an identification code indicative of the surgical instrument, the first connection part insertable into the second connection part so that the surgical instrument can be identified in a non-contact manner by the identifying circuit associated with the generator.

Abstract
A qualifying connection for an instrument attaches to a source of electrosurgery energy and to the instrument and has first and second parts coupled to the instrument and the source, respectively. Optical couplings on the connection transmit invisible energy to identify the instrument and are proximate on the first and second parts. A light modifier on the first part is proximal to the second part for modification of radiation in the infrared wavelengths so infrared transmitters encode signals and non-contact coded proximity detectors on the second part are the coupled detectors. Mechanical attachments include conjugating male and female portions physically extending between the parts for mating engagement. An identifying circuit couples to the second part and responds to invisible light optically communicated across the couplings for verifying the type of instrument connected by the cable to the source. A method of using the connection has steps including juxtaposing and conjugating the parts with attachments and couplings for transmitting invisible optical energy to identify the instrument. The method includes modifying the invisible optical energy with geographically disposed proximate couplings of the parts when the attachments engage and the couplings are proximate. Passing and assessing signals of the modified energy are transmitted trough the connection and to an identifying circuit in the source.

15. A method of identifying a surgical instrument for determination of application of energy comprising:
-
providing a first connection part having a light modifier in the form of a diffuse surface corresponding to a predetermined code particular to the type of instrument;
inserting the first connection part into a second connection part of a generator, the second connection part having a plurality of transmitters for transmitting an unfocused beam of light to the diffuse surface, and the first connection part being inserted so the diffuse surface and the transmitters are in proximity;
transmitting optical energy from the transmitters of the second connection part to the diffuse surface of the first connection part;
processing the modified light in the generator to determine the type of surgical instrument connected to the generator; and
controlling the activation and deactivation of the generator in response to the determination of the type of surgical instrument. - View Dependent Claims (16, 17, 18)
