## Abstract

A surgical clamp for occluding a body conduit includes first and second jaws moveable relative to each other in a generally parallel relationship. A handle assembly is operable to move the jaws relative to each other between a space position and proximate position. The first jaw has an elongate configuration characterized by a length and a width. First portions of the first jaw have in cross section a first shape which remains generally constant in area along the first jaw, while second portions have in cross section a second shape which varies in area along the length of the first jaw. The resulting clamp has a low profile jaw design which dimensional-shaped cross section which provide increased stiffness and reduced flexibility.

## Claims

### Claim 1

A surgical clamp for occluding the body conduit comprising:
a first jaw;
a second jaw moveable relative to the first jaw;
a handle assembly operable to move the first jaw and the second jaw relative to each other between a spaced position and a proximate position;
the first jaw having an elongate configuration characterized by a length along a Z-axis, a width along a Y-axis, and a thickness along an X-axis, wherein the jaw extends along the Z-axis but moves between the spaced position and the proximate position along the X-axis, and the Y-axis is perpendicular to both the X-axis and the Z-axis;
first portions of the first jaw having a first width and having in cross section a first shape which remains generally constant in area along the length of the first jaw;
a removable insert mounted on the first portions of the first jaw; and
second portions of the first jaw having a second width greater than the first width and arranged under the first portions having in cross section a second shape which changes in area along the length of the first jaw, the first and second widths being disposed along the Y-axis.

### Claim 2 (depends on 1)

The surgical clamp recited in claim 1 wherein the second portions of the first jaw are disposed outwardly of the first portions of the first jaw.

### Claim 3 (depends on 1)

The surgical clamp recited in claim 1, wherein:
the first and second portions are integrally formed into a beam having in radial cross section a non-rectangular shape.

### Claim 4 (depends on 1)

The surgical clamp recited in claim 1, wherein:
the first jaw is configured to have a pivotal relationship with the insert at the distal end; and
the first jaw is configured to have a snap-fit relationship with the insert at the proximal end.

### Claim 5 (depends on 1)

The clamp of claim 1 wherein the first portion of the first jaw has a first surface extending lengthwise along the first portion of the first jaw and the second portion of the first jaw has a second surface extending lengthwise along the second portion of the first jaw, the second surface being disposed farther from the second jaw than the first surface.

### Claim 6 (depends on 1)

The clamp of claim 1, wherein the insert has a first surface area and the first portion has a second surface area, the first surface area being greater than the second surface area of the first portion.

### Claim 7 (depends on 1)

The clamp of claim 1, wherein the insert has a generally uniform width throughout the length of the first jaw, the width of the insert being greater than the width of the first portion.

### Claim 8 (depends on 1)

The clamp of claim 1, wherein the handle assembly is disposed along a first axis and the first and second jaws are disposed along a second axis traverse to the first axis.

### Claim 9

A surgical clamp for occluding a body conduit, comprising:
a handle assembly;
a pair of opposing jaws movable by the handle assembly in a plane of operation along an X-axis between a spaced orientation wherein the jaws are spread to receive the body conduit, and a proximate orientation wherein the jaws are substantially closed to occlude the body conduit;
a removable insert having a first width;
at least one of the jaws having in radial cross section a non-rectangular shape and including a first longitudinal portion and a second longitudinal portion;
the first portion of the jaw having a length and a generally uniform second width along the length of the first portion and being sized and configured to receive the insert;
the second portion of the jaw having a third width and defining with the first portion the thickness of the jaw; and
the first width of the insert being less than the width of the second longitudinal portions and greater than the second width of the first longitudinal portions of the jaw, the first, second and third widths all disposed along a Y-axis, the Y-axis being perpendicular to the X-axis.

### Claim 10 (depends on 9)

The surgical clamp recited in claim 9, wherein the insert has a longitudinal channel and is carried by at least one jaw;
the first portion being disposed within the longitudinal channel of the insert; and
the second portion being disposed adjacent to the insert.

### Claim 11 (depends on 10)

The surgical clamp recited in claim 10, wherein:
the second portion is disposed in an abutting relationship with the insert.

### Claim 12 (depends on 9)

The surgical clamp recited in claim 9, wherein:
the first and the second portions integrally form a structural beam having in radial cross section a shape that is non-rectangular.

### Claim 13 (depends on 12)

The surgical clamp recited in claim 12 wherein the structural beam is one of a trapezoidal beam, a U-beam, a V-beam, an I-beam, a T-beam and an L-beam.

### Claim 14 (depends on 9)

The clamp of claim 9, wherein the first portion has a first surface extending lengthwise along the first portion and the second portion has a second surface extending lengthwise along the second portion, the second surface being disposed farther from the other jaw than the first surface.

### Claim 15 (depends on 9)

The clamp of claim 9, wherein the insert has a first surface area and the first portion has a second surface area, the first surface area being greater than the second surface area.

### Claim 16 (depends on 9)

The clamp of claim 9, wherein the handle assembly is disposed along a plane of operation that is traverse to the plane of operation of the jaws.

### Claim 17 (depends on 9)

The clamp of claim 9, wherein the jaws are orientated generally orthogonal to the handle assembly.
