Rfid identification systems for surgical instruments

Abstract

A surgical device for applying clips is disclosed including a cartridge, an RFID tag, and a controller. The cartridge includes a plurality of clips. A crimping drive is configured to move a first jaw and a second jaw to a closed position during a crimping stroke. One of the plurality of clips is crimped around tissue during the crimping stroke. Stored data on the RFID tag relates to an identifying characteristic of at least one of the plurality of clips within the cartridge. An RFID scanner is configured to receive a first signal from the RFID tag in response to an interrogation signal. The first signal includes the stored data on the RFID tag. A controller in communication with the RFID scanner is configured to compare the stored data to a set of compatibility data and vary an operational parameter of the surgical device based on the stored data.

20 claims: 3 independent, 17 dependent

  1. 1
    CLAIMS WHAT IS CLAIMED IS:1. A surgical suturing system, comprising: an elongate shaft;a firing drive;an end effector extending distally from said elongate shaft, wherein said end effector comprises: a needle track;and a replaceable needle guided by said needle track and actuated by said firing drive through a firing stroke, wherein said replaceable needle comprises: suturing material attached thereto;and an RFID tag comprising stored data;an RFID scanner, wherein said RFID scanner receives a signal from said RFID tag comprising said stored data, and wherein said signal is indicative of said stored data;and a controller in communication with said RFID scanner, wherein said controller is configured to: determine compatibility between said replaceable needle and said surgical suturing system based on said stored data received by said RFID scanner;and prevent said surgical suturing system from performing the firing stroke when said replaceable needle is incompatible with said surgical suturing system.
  2. 2
    The surgical suturing system of Claim 1 , wherein said controller is further configured to prevent said surgical suturing system from performing the firing stroke when said RFID scanner fails to receive said signal from said RFID tag.
  3. 3
    The surgical suturing system of Claim 1 , wherein said RFID scanner comprises reading capabilities and writing capabilities.
  4. 4
    The surgical suturing system of Claim 1 , wherein said RFID tag is positioned on said replaceable needle.
  5. 5
    The surgical suturing system of Claim 1 , wherein said RFID tag is positioned on said suturing material.
  6. 6
    The surgical suturing system of Claim 1 , wherein said RFID tag comprises an integrated battery.
  7. 7
    The surgical suturing system of Claim 6, wherein said replaceable needle is stored in a packaging prior to being attached to said surgical suturing system, wherein said packaging comprises a first layer and a second layer, wherein said first layer and said second layer form a seal around said replaceable needle, and wherein said RFID tag is positioned on said packaging.
  8. 8
    The surgical suturing system of Claim 7, further comprising an insulator attached to said second layer which electrically decouples said integrated battery from said RFID tag, wherein said RFID tag is attached to said first layer of said packaging, wherein said insulator detaches from said integrated battery when said first layer is removed from said second layer, and wherein said RFID tag becomes active and transmits said stored data when said insulator is detached from said integrated battery.
  9. 9
    A surgical device for applying clips, wherein said surgical device comprises:an elongate shaft extending from a housing;an end effector extending from said elongate shaft, wherein said end effector comprises: a first jaw;and a second jaw, wherein said first jaw and said second jaw are movable relative to each other between an open position and a closed position;a cartridge, comprising: a storage chamber;and a plurality of clips removably positioned within said storage chamber;a crimping drive configured to move said first jaw and said second jaw to said closed position during a crimping stroke, wherein one of said plurality of clips is crimped around tissue of a patient during the crimping stroke;an RFID tag comprising a first set of information, wherein said first set of information corresponds to said cartridge;an RFID scanner configured to receive a first signal from said RFID tag, wherein said first signal comprises said first set of information;and a controller in communication with said RFID scanner, wherein said controller is configured to: determine if said cartridge is compatible with said surgical device by comparing said first set of information received by said RFID scanner to a set of compatibility data stored in a memory of said controller;permit said surgical device to perform the crimping stroke when said controller determines said cartridge is compatible for use with said surgical device;prevent said surgical device from performing the crimping stroke when said controller is unable to recognize said cartridge as compatible for use with said surgical device;and prevent said surgical device from performing the crimping stroke when said RFID scanner does not receive said first signal.
  10. 10
    The surgical device of Claim 9, wherein said RFID tag is positioned on said cartridge.
  11. 11
    1 1 . The surgical device of Claim 9, wherein said RFID tag is positioned on a first clip from said plurality of clips and a second RFID tag is positioned on a second clip from said plurality of clips, and wherein said second RFID tag comprises a second set of information.
  12. 12
    The surgical device of Claim 1 1 , wherein said controller is configured to prevent the crimping stroke when said RFID scanner receives said first signal from said RFID tag and a second signal from said second RFID tag.
  13. 13
    The surgical device of Claim 1 1 , wherein said RFID scanner comprises a communication range, wherein said RFID scanner can only communicate with RFID tags positioned within said communication range, and wherein said controller is configured to prevent the crimping stroke if said RFID scanner receives signals from more than one RFID tag.
