Adapter assemblies for interconnecting surgical loading units and handle assemblies
First Claim
1. An adapter assembly, comprising:
- an elongated body including a proximal portion configured to couple to a handle assembly, and a distal portion configured to couple to a surgical loading unit;
a circuit assembly disposed within the distal portion of the elongated body and configured to be in communication with a handle assembly; and
an annular member rotatably disposed within the distal portion of the elongated body and including at least one electrical contact, the annular member being rotatable between a first orientation, in which the at least one electrical contact of the annular member is electrically isolated from the circuit assembly, and a second orientation, in which the at least one electrical contact of the annular member is electrically connected with the circuit assembly.

Abstract
An adapter assembly includes an elongated body, a circuit assembly, and an annular member. The elongated body includes a proximal portion configured to couple to a handle assembly, and a distal portion configured to couple to a surgical loading unit. The circuit assembly is disposed within the distal portion of the elongated body and configured to be in communication with a handle assembly. The annular member is rotatably disposed within the distal portion of the elongated body and includes an electrical contact. The annular member is rotatable between a first orientation, in which the electrical contact of the annular member is electrically isolated from the circuit assembly, and a second orientation, in which the electrical contact of the annular member is electrically connected to the circuit assembly.

7. A surgical instrument, comprising:
-
a handle assembly including a processor; a surgical loading unit having an end effector disposed at a distal end thereof; and an adapter assembly including; an elongated body including a proximal portion configured to couple to the handle assembly, and a distal portion configured to couple to a proximal end of the surgical loading unit; a circuit assembly disposed within the distal portion of the elongated body and configured to be in communication with the processor of the handle assembly; and an annular member rotatably disposed within the distal portion of the elongated body and including at least one electrical contact, wherein upon coupling the proximal end of the surgical loading unit to the distal portion of the elongate body of the adapter assembly, rotation of the surgical loading unit rotates the annular member from a first orientation, in which the at least one electrical contact of the annular member is electrically isolated from the circuit assembly, to a second orientation, in which the at least one electrical contact of the annular member is electrically connected with the circuit assembly such that the circuit assembly communicates to the processor that the surgical loading unit is coupled to the adapter assembly. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
