Patent ID: 7857851

Claim:
A surgical sizing instrument set comprising: a first surgical sizing instrument including: a hollow tube having a proximal end and a distal end; an elongated sizing template extending through the hollow tube, the elongated sizing template having: a proximal end; a distal end; an intermediate portion between the proximal end and distal end; a first resilient segment adjacent to the intermediate portion; a second resilient segment adjacent to the first resilient segment and positioned between the first resilient segment and the distal end of the elongated sizing template; wherein the elongated sizing template is reciprocable in the hollow tube between an extended position and a retracted position; and wherein the first resilient segment and second resilient segment have a first angular relationship when the elongated sizing template is in the extended position and a second angular relationship when the elongated sizing template is in the retracted position, the first angular relationship being different from the second angular relationship; the surgical sizing instrument set further comprising a second surgical sizing instrument including: a hollow tube having a proximal end and a distal end; an elongated sizing template extending through the hollow tube, the elongated sizing template having: a proximal end; a distal end; an intermediate portion between the proximal end and distal end; a first resilient segment adjacent to the intermediate portion; a second resilient segment adjacent to the first resilient segment and positioned between the first resilient segment and the distal end of the elongated sizing template; wherein the elongated sizing template is reciprocable in the hollow tube between an extended position and a retracted position; and wherein the first resilient segment and second resilient segment have a first angular relationship when the elongated sizing template is in the extended position and a second angular relationship when the elongated sizing template is in the retracted position, the first angular relationship being different from the second angular relationship; wherein the length of at least one of resilient segments of the first surgical sizing instrument is greater than the length at least one of the resilient segments of the second surgical sizing instrument.
