Abstract

An adjustable length laparoscopic instrument is provided. The instrument includes a shaft with a shaft distal end and a shaft proximal end. The instrument further includes an actuation rod with an actuation rode distal end and an actuation rod proximal end. The actuation rod is receivable by the shaft such that the actuation rod can translate longitudinally relative to the shaft to actuate an end effector. The instrument further includes a handle configured to hold the shaft and the actuation rod. The handle is configured to cause the actuation rod to translate longitudinally relative to the shaft to actuate the end effector. The instrument further includes a length adjustment mechanism configured to adjust a shaft length. The shaft length is defined between the handle and the shaft distal end.
