Abstract

A surgical stapling instrument includes a handle assembly, a surgical loading unit, and an adapter assembly interconnecting the handle assembly and the surgical loading unit. The surgical loading unit includes a memory having instructions stored therein that, when executed by a processor of the handle assembly, override the instructions stored in the memory of the handle assembly and implement operating parameters of the surgical loading unit that are unique to a tissue type or a particular surgical procedure to be performed by the surgical loading unit.

Claims (7)

1. A surgical loading unit for use with a surgical stapling instrument, the surgical loading unit comprising: a staple cartridge assembly; an anvil assembly operably coupled to the staple cartridge assembly, and A memory associated with at least one of the staple cartridge assembly or the anvil assembly, the memory having instructions stored therein that, when executed, direct the processor to adapt operation of the adapter assembly or handle assembly from a preset mode of operation to a unique mode of operation, wherein the preset mode of operation includes automatically adjusting a staple firing rate of the surgical loading unit based on the sensed tissue thickness, and the unique mode of operation includes setting a constant staple firing rate of the surgical loading unit.
2. The surgical loading unit of claim 1, wherein the memory further has data stored therein relating to the surgical loading unit.
3. The surgical loading unit of claim 2, wherein the data comprises at least one of a serial number of the surgical loading unit, a type of the surgical loading unit, a size of the surgical loading unit, a staple size contained in the surgical loading unit, information identifying whether the surgical loading unit has been fired, a length of a firing stroke of the surgical loading unit, or a maximum number of uses of the surgical loading unit.
4. A surgical stapling instrument, comprising: A handle assembly, the handle assembly comprising: a memory having instructions stored therein, and A processor configured to execute the instructions, and A surgical loading unit configured to be coupled to the handle assembly, the surgical loading unit comprising: a staple cartridge assembly; an anvil assembly operably coupled to the staple cartridge assembly, and A memory having instructions stored therein that, when executed by the processor of the handle assembly, override the instructions stored in the memory of the handle assembly and direct the processor to adapt operation of an adapter assembly or the handle assembly from a preset mode of operation to a unique mode of operation, wherein the preset mode of operation comprises automatically adjusting a staple firing rate of the surgical loading unit based on a sensed tissue thickness and the unique mode of operation comprises setting a constant staple firing rate of the surgical loading unit.
5. The surgical stapling instrument of claim 4, wherein said memory of said surgical loading unit further has data stored therein relating to said surgical loading unit.
6. The surgical stapling instrument of claim 5, wherein said data comprises at least one of a serial number of said surgical loading unit, a type of said surgical loading unit, a size of said surgical loading unit, a staple size, information identifying whether said surgical loading unit has been fired, a length of a firing stroke of said surgical loading unit, or a maximum number of uses of said surgical loading unit.
7. The surgical stapling instrument of claim 4, further comprising an adapter assembly configured to interconnect said surgical loading unit and said handle assembly.

Description

Surgical stapling instrument and surgical loading unit therefor Technical Field The present disclosure relates to surgical stapling instruments. More particularly, the present disclosure relates to a smart loading unit for a surgical stapling instrument. Background Surgical stapling instruments for manipulation on tissue are well known in the art and may include a handle assembly, a body portion extending distally from the handle assembly, and a surgical loading unit supported on a distal tip portion of the body portion. The surgical loading unit includes a first jaw and a second jaw that are movable relative to each other between a non-approximated position and an approximated position. In a surgical stapling instrument, the first jaw is an anvil assembly and the second jaw is a cartridge assembly. The surgical stapling instrument can be preprogrammed to adjust firing speed, clamping force, etc., based on the characteristics of the tissue being treated (e.g., tissue thickness). For example, when tissue is determined to be relatively thick, instructions stored in the handle assembly of the surgical stapling instrument may cause the handle assembly to fire staples from an attached surgical loading unit and/or advance the knife bar at a reduced speed. Disclosure of Invention In accordance with one aspect of the present disclosure, a surgical loading unit for use with a surgical stapling instrument is provided. The surgical loading unit includes a staple cartridge assembly, an anvil assembly operably coupled to the staple cartridge assembly, and a memory associated with at least one of the staple cartridge assembly or the anvil assembly. The memory has instructions stored therein that, when executed, implement operating parameters of the surgical loading unit. The operating parameters are unique to the tissue type or the particular surgical procedure to be performed by the surgical loading unit. In aspects, the operating parameters may include a staple firing speed, a staple firing force, a clamping speed, and/or a clamping force of the surgical loading unit. In aspects, the firing rate may be unique to the tissue type or the particular surgical procedure to be performed by the surgical loading unit. In aspects, the firing force may be unique to the tissue type or the particular surgical procedure to be performed by the surgical loading unit. In aspects, the particular surgical procedure to be performed by the surgical loading unit may include endoscopic gastrointestinal anastomosis, tissue resection, or lesion resection. In aspects, the memory may have data stored therein relating to the surgical loading unit. In aspects, the data may include a serial number of the surgical loading unit, a type of the surgical loading unit, a size of the surgical loading unit, a staple size included in the surgical loading unit, information identifying whether the surgical loading unit has been fired, a length of a firing stroke of the surgical loading unit, and/or a maximum number of uses of the surgical loading unit. In aspects, the instructions stored in the memory may override a program in a corresponding adapter assembly or handle assembly when executed. The operating parameters may be different from the operating parameters in the program. According to another aspect of the present disclosure, a surgical stapling instrument is provided and includes a handle assembly and a surgical loading unit configured to be coupled to the handle assembly. The handle assembly includes a memory having instructions stored therein, and a processor configured to execute the instructions. The surgical loading unit includes a staple cartridge assembly, an anvil assembly operably coupled to the staple cartridge assembly, and a memory. The memory has instructions stored therein that, when executed by the processor of the handle assembly, override the instructions stored in the memory of the handle assembly and implement operating parameters of the surgical loading unit that are unique to a tissue type or a particular surgical procedure to be performed by the surgical loading unit. In aspects, the operating parameters may include a staple firing speed, a staple firing force, a clamping speed, and/or a clamping force of the surgical loading unit. In aspects, the firing rate may be unique to the tissue type or the particular surgical procedure to be performed by the surgical loading unit. In aspects, the firing force may be unique to the tissue type or the particular surgical procedure to be performed by the surgical loading unit. In aspects, the particular surgical procedure to be performed by the surgical loading unit may include endoscopic gastrointestinal anastomosis, tissue resection, or lesion resection. In aspects, the memory of the surgical loading unit may have data stored therein relating to the surgical loading unit. In aspects, the data may include a serial number of the surgical loading unit, a type of the surgical loading unit, a s
