A forceps (10, 10'), comprising: an end effector assembly, including: first and second jaw members (110, 120), each of the jaw members including a proximal flange (114, 124) extending therefrom, each proximal flange defining a bifurcated configuration having first and second spaced-apart flange components (132, 134, 152, 154), the first flange component of the first jaw member configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling (162, 144) and the first flange component of the second jaw member configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling (142, 164) different from the first protrusion-aperture coupling, at least one of the first and second jaw members pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween, characterised in that each of the proximal flanges includes a protrusion (142, 162) extending outwardly from one of the flange components thereof and an aperture (164, 144) defined transversely through the other flange component thereof, the protrusion of each proximal flange configured to engage the aperture of the other proximal flange for pivotably coupling the first and second jaw members to one another. an end effector assembly, including: first and second jaw members (110, 120), each of the jaw members including a proximal flange (114, 124) extending therefrom, each proximal flange defining a bifurcated configuration having first and second spaced-apart flange components (132, 134, 152, 154), the first flange component of the first jaw member configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling (162, 144) and the first flange component of the second jaw member configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling (142, 164) different from the first protrusion-aperture coupling, at least one of the first and second jaw members pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween, characterised in that each of the proximal flanges includes a protrusion (142, 162) extending outwardly from one of the flange components thereof and an aperture (164, 144) defined transversely through the other flange component thereof, the protrusion of each proximal flange configured to engage the aperture of the other proximal flange for pivotably coupling the first and second jaw members to one another. first and second jaw members (110, 120), each of the jaw members including a proximal flange (114, 124) extending therefrom, each proximal flange defining a bifurcated configuration having first and second spaced-apart flange components (132, 134, 152, 154), the first flange component of the first jaw member configured to pivotably engage the second flange component of the second jaw member via a first protrusion-aperture coupling (162, 144) and the first flange component of the second jaw member configured to pivotably engage the second flange component of the first jaw member via a second protrusion-aperture coupling (142, 164) different from the first protrusion-aperture coupling, at least one of the first and second jaw members pivotable relative to the other about the first and second protrusion-aperture couplings between a spaced-apart position and an approximated position for grasping tissue therebetween, characterised in that each of the proximal flanges includes a protrusion (142, 162) extending outwardly from one of the flange components thereof and an aperture (164, 144) defined transversely through the other flange component thereof, the protrusion of each proximal flange configured to engage the aperture of the other proximal flange for pivotably coupling the first and second jaw members to one another.
