Abstract
An authentication system for use in a surgical stapling device includes an authentication board assembly disposed at a proximal end of a loading unit and having a contact assembly, and an adapter board assembly disposed at a distal end of an adapter assembly. When the loading unit is engaged with the adapter assembly, the authentication board engages the adapter board assembly.
Claims13
An authentication system for a surgical instrument, comprising:
- an authentication board assembly operably engaged to a loading unit of the surgical instrument, the authentication board assembly including:
- a first circuit board having a proximal end and a distal end;
- a contact assembly operably engaged to the first circuit board;
- and
- a chip operably engaged to the first circuit board and in operable communication with the contact assembly;
- an adapter board assembly operably associated with the surgical instrument;
- a second circuit board operably engaged to the adapter board assembly;
- at least one contact operably engaged to the second circuit board;
- and
- a spring clip configured to secure the second circuit board to the adapter board assembly,
- wherein the contact assembly of the authentication board assembly is configured to engage the at least one contact of the adapter board assembly, and
- wherein the contact assembly of the authentication board assembly includes:
- a first contact arm having a first contact member orthogonally disposed and secured to an upper portion of a proximal end of the first contact arm;
- a second contact arm having a second contact member orthogonally disposed and secured to an upper portion of a proximal end of the second contact arm;
- and
- a solder tab orthogonally disposed and secured to a lower portion of a distal end of at least one of the first contact arm or the second contact arm.
