Method for producing a surgical instrument comprising a smart electrical system

A method for producing a surgical instrument surgical instrument, comprising:

• obtaining a housing, wherein the housing comprises a distal end, and wherein the distal end comprises a shaft interface surface and a first set of magnetic elements;
• obtaining a shaft, wherein the shaft comprises a proximal end, wherein the proximal end comprises:
• a housing interface surface;
• and
• a second set of magnetic elements;
• and
• aligning the shaft with respect to the housing, wherein the shaft interface surface is configured to engage the shaft at the housing interface surface, wherein an attractive magnetic force is configured to pull the housing towards the shaft when the first set of magnetic elements interacts with the second magnetic elements.

A method for producing a modular surgical instrument, comprising:

• obtaining a housing, wherein the housing comprises:
• a first array of magnetic elements;
• and
• an attachment interface;
• obtaining a shaft assembly, wherein the shaft assembly is operably attachable to the attachment interface, and wherein the shaft assembly comprises a second array of magnetic elements;
• and
• attaching the shaft assembly to the housing, wherein the first array of magnetic elements and the second array of magnetic elements co-operate to generate a repulsive magnetic force which repulses the shaft assembly from the attachment interface when the shaft assembly is positioned on a first side of a field threshold, and wherein the first array of magnetic elements and the second array of magnetic elements co-operate to generate an attractive magnetic force which pulls the shaft assembly towards the attachment interface when the shaft assembly is positioned on a second side of the field threshold.
