Surgical instrument with jaw member
First Claim
1. A surgical instrument, the instrument comprising:
- a shaft;
an end effector positioned at a distal portion of the shaft, the end effector comprising;
a first jaw comprising a first jaw knife slot parallel to a transection plane; and
a second jaw comprising a second jaw knife slot parallel to the transection plane;
a movable cutting member translatable distally and proximally within the first and second jaw knife slots, wherein the cutting member comprises;
a first band comprising a first band slot having a distal portion and a proximal portion, wherein a width of the first band slot at the distal portion of the first band slot is larger than a width of the first band slot at the proximal portion of the first band slot;
a second band comprising a second band slot having a distal portion and a proximal portion, wherein a width of the second band slot at the proximal portion of the second band slot is larger than a width of the second band slot at the distal portion of the second band slot; and
a pin positioned within the first band slot and the second band slot, wherein the pin comprises a middle portion having a middle portion diameter and at least one outer portion having an outer portion diameter, wherein the outer portion diameter is;
larger than the width of the first band slot at the proximal portion of the first band slot;
larger than the width of the second band slot at the distal portion of the second band slot;
smaller than the width of the first band slot at the distal portion of the first band slot; and
smaller than the width of the second band slot at the proximal portion of the second band slot.

Abstract
A surgical instrument comprises a shaft, end effector and movable cutting member. The movable cutting member may comprise a first band comprising a first band slot having a distal portion and a proximal portion. A width of the first band slot at the distal portion may be larger than a width of the first band slot at the proximal portion. The movable cutting member may comprise a second band comprising a second band slot having a distal portion and a proximal portion. A width of the second band slot at the proximal portion may be larger than a width of the second band slot at the distal portion. The movable cutting member may comprise a pin positioned within the first band slot and the second band slot. The pin may comprise a middle portion having a middle portion diameter and at least one outer portion having an outer portion diameter.
