  • Surgical instruments often include a handle assembly that is configured to control a function of an end effector assembly that is directly or indirectly engaged therewith. End effectors are typically available in different lengths depending on the desired surgical function. When a particular handle assembly does not include a reliable way to limit the longitudinal travel of a drive rod, for instance, it may be suitable to provide end effectors having one length to be used with such a handle assembly to avoid damaging portions of the surgical instrument, for instance.
  • the disclosure relates to a surgical kit including a handle assembly, an adapter assembly, and a first end effector.
  • the handle assembly includes a handle portion, an elongated portion extending distally from the handle portion, an actuation switch, and a firing rod. At least a portion of the firing rod extends through the elongated portion. Actuation of the actuation switch causes the firing rod to move distally relative to the handle portion.
  • the adapter assembly is configured to selectively engage the handle assembly and includes a connector, an adapter drive rod, and a biasing element. A proximal portion of the connector is configured to engage a distal portion of the firing rod of the handle assembly.

  • the handle assembly is configured such that the actuation of the actuation switch causes a second distal movement of the firing rod, a corresponding second distal movement of the connector of the adapter assembly, and results in the drive assembly of the first end effector remaining in its longitudinal position. It is further disclosed the adapter assembly is configured such that that the adapter drive rod remains in its longitudinal position in response to the second distal movement of the firing rod, and that the adapter assembly and the handle assembly are configured such that the second distal movement of the firing rod causes the biasing element to compress the amount of the second distal movement of the firing rod.
