## Abstract

A handheld electromechanical surgical device includes a handle assembly, an adapter assembly, a reload, and an electrical assembly. The handle assembly includes a connecting portion having an electrical connector supported therein. The adapter assembly includes an adapter housing selectively connectable to the connecting portion of the handle assembly and an outer tube extending distally from the adapter housing. The reload includes a housing selectively connectable to the outer tube of the adapter assembly and a circuit board assembly disposed within the reload housing. The electrical assembly includes a flex cable having an elongate body positionable against an outer surface of the adapter assembly. A proximal end of the flex cable is positionable within a cavity defined in the adapter housing and configured to electrically connect with the electrical connector of the handle assembly. A distal end of the flex cable is coupled to the circuit board assembly of the reload.

## Claims

### Claim 1

A handheld electromechanical surgical device comprising:
a handle assembly including a connecting portion having an electrical connector supported therein;
an adapter assembly including an adapter housing and an outer tube extending distally from the adapter housing, the adapter housing selectively connectable to the connecting portion of the handle assembly;
a reload including a reload housing selectively connectable to the outer tube of the adapter assembly, the reload including a circuit board assembly disposed within the reload housing; and
an electrical assembly including a flex cable having an elongate body positionable against an outer surface of the adapter assembly, the flex cable including a proximal end and a distal end, the proximal end positionable within a cavity defined in the adapter housing and configured to electrically connect with the electrical connector of the handle assembly, and the distal end coupled to the circuit board assembly of the reload.

### Claim 2 (depends on 1)

The surgical device according to claim 1, wherein the proximal end of the flex cable includes a pin connector assembly, the pin connector assembly configured to interface with the electrical connector of the handle assembly.

### Claim 3 (depends on 2)

The surgical device according to claim 2, wherein the pin connector assembly includes electrical contact blades supported on a circuit board, the electrical contact blades configured to contact the electrical connector of the handle assembly when the adapter assembly is connected to the handle assembly.

### Claim 4 (depends on 1)

The surgical device according to claim 1, wherein the distal end of the flex cable is permanently secured to the circuit board assembly of the reload.

### Claim 5 (depends on 1)

The surgical device according to claim 1, wherein a distal portion of the flex cable extends through a port defined in the reload housing.

### Claim 6 (depends on 1)

The surgical device according to claim 1, wherein the flex cable includes an adhesive disposed on a first side of the elongate body of the flex cable and positionable against the outer surface of the adapter assembly.

### Claim 7 (depends on 1)

The surgical device according to claim 1, wherein the outer tube of the adapter assembly includes an electrical connector secured therein, the electrical connector electrically coupled to a strain sensor supported within the outer tube, and the flex cable includes a strain sensor electrical connector configured to mate with the electrical connector of the adapter assembly.

### Claim 8 (depends on 1)

The surgical device according to claim 1, wherein the flex cable includes a printed circuit board disposed or integrated thereon.

### Claim 9 (depends on 8)

The surgical device according to claim 8, wherein the printed circuit board is positioned along a proximal portion of the flex cable aligned with the adapter housing of the adapter assembly.

### Claim 10 (depends on 8)

The surgical device according to claim 8, wherein wings extend laterally from the printed circuit board of the flex cable, the wings including an adhesive for securing the printed circuit board to the adapter assembly.
