Abstract

A fingertip-actuated surgical clip applier includes a first body and a second body substantially structurally identical to the first body. The first body includes a main section and a first jaw extending in a distal direction from the main section. The main section includes a hinge region and a first longitudinal wall extending between the first jaw and the hinge region. The first longitudinal wall includes a first outside surface adapted for contacting a first fingertip. The second body includes a second jaw and a second longitudinal wall. The second longitudinal wall includes a second outside surface adapted for contacting a second fingertip. The second body is inverted in relation to the first body and is pivotably connected to the hinge region. The first and second jaws are pivotable toward each other to a closed position and away from each other to an open position.

Claims

1. A fingertip-actuated surgical clip applier comprising:

(a) a first body comprising a main section and a first jaw extending in a distal direction from the main section, the main section comprising a hinge region and a first longitudinal wall extending between the first jaw and the hinge region, the first longitudinal wall comprising a first outside surface adapted for contacting a first fingertip; and

(b) a second body substantially structurally identical to the first body and comprising a second jaw and a second longitudinal wall, the second longitudinal wall comprising a second outside surface adapted for contacting a second fingertip, the second body inverted in relation to the first body and pivotably connected to the hinge region, wherein the first and second jaws are pivotable toward each other to a closed position and away from each other to an open position and wherein the first body comprises a first boss and a first aperture, the second body comprises a second boss and a second aperture, the first boss is pivotably disposed within the second aperture, and the second boss is pivotably disposed within the first aperture.

2. The clip applier according to claim 1 comprising a first rib extending from the first body toward the second body and a second rib extending from the second body toward the first body wherein, at both the open and closed positions, the first rib is adjacent to the second body to retain the first boss in the second aperture, and the second rib is adjacent to the first body to retain the second boss in the first aperture.

3. A fingertip-actuated surgical clip applier comprising:

(a) a first body comprising a main section and a first jaw extending in a distal direction from the main section, the main section comprising a hinge region and a first longitudinal wall extending between the first jaw and the hinge region, the first longitudinal wall comprising a first outside surface adapted for contacting a first fingertip; and

(b) a second body substantially structurally identical to the first body and comprising a second jaw and a second longitudinal wall, the second longitudinal wall comprising a second outside surface adapted for contacting a second fingertip, the second body inverted in relation to the first body and pivotably connected to the hinge region, wherein the first and second jaws are pivotable toward each other to a closed position and away from each other to an open position and wherein the first body comprises a first shoulder and a first protrusion transversely spaced from the first shoulder, the second body comprises a second shoulder and a second protrusion transversely spaced from the second shoulder and, at the open position, the first shoulder abuts against the second protrusion and the second shoulder abuts against the first protrusion to prevent further pivoting of the first and second jaws away from each other.

4. The clip applier according to claim 3 wherein the first body comprises a first recess defined between the first longitudinal wall and the first shoulder, the second body comprises a second recess defined between the second longitudinal wall and the second shoulder and, during pivoting of the first and second jaws between the open and closed positions, the first protrusion slides along the second recess and the second protrusion slides along the first recess.

5. A fingertip-actuated surgical clip applier comprising:

(a) a first body comprising a first main section and a first jaw extending in a distal direction from the first main section, the first main section comprising a first hinge region and a first longitudinal wall extending between the first jaw and the first hinge region, the first longitudinal wall comprising a first outside surface adapted for contacting a first fingertip and an opposing first inside surface, wherein the first body comprises a first shoulder and a first protrusion transversely spaced from the first shoulder; and

(b) a second body comprising a second main section and a second jaw extending in the distal direction from the second main section in opposing relation to the first jaw, the second main section comprising a second hinge region and a second longitudinal wall extending between the second jaw and the second hinge region, the second longitudinal wall comprising a second outside surface adapted for contacting a second fingertip and a second inside surface generally facing the first inside surface, wherein the second hinge region is pivotably connected to the first hinge region, and the first and second jaws are pivotable toward each other to a closed position and away from each other to an open position and wherein the first body comprises a first stop surface spaced from the first longitudinal wall, the second body comprises a second stop surface spaced from the second longitudinal wall and, at the closed position, the first and second stop surfaces abut each other to prevent further pivoting of the first and second jaws toward each other, wherein the second body comprises a second shoulder and a second protrusion transversely spaced from the second shoulder and, at the open position, the first shoulder abuts against the second protrusion and the second shoulder abuts against the first protrusion to prevent further pivoting of the first and second jaws away from each other.

6. The clip applier according to claim 5 wherein the abutment of the first and second stop surfaces maintains a gap between the first and second jaws to prevent the first and second jaws from contacting each other.

7. A fingertip-actuated surgical clip applier comprising:

(a) a first body comprising a first main section and a first jaw extending in a distal direction from the first main section, the first main section comprising a first hinge region and a first longitudinal wall extending between the first jaw and the first hinge region, the first longitudinal wall comprising a first outside surface adapted for contacting a first fingertip and an opposing first inside surface; and

(b) a second body comprising a second main section and a second jaw extending in the distal direction from the second main section in opposing relation to the first jaw, the second main section comprising a second hinge region and a second longitudinal wall extending between the second jaw and the second hinge region, the second longitudinal wall comprising a second outside surface adapted for contacting a second fingertip and a second inside surface generally facing the first inside surface, wherein the second hinge region is pivotably connected to the first hinge region, and the first and second jaws are pivotable toward each other to a closed position and away from each other to an open position and wherein the first body comprises a first shoulder and a first protrusion transversely spaced from the first shoulder, the second body comprises a second shoulder and a second protrusion transversely spaced from the second shoulder and, at the open position, the first shoulder abuts against the second protrusion and the second shoulder abuts against the first protrusion to prevent further pivoting of the first and second jaws away from each other.

8. The clip applier according to claim 7 wherein the first body comprises a first recess defined between the first longitudinal wall and the first shoulder, the second body comprises a second recess defined between the second longitudinal wall and the second shoulder and, during pivoting of the first and second jaw between the open and closed positions, the first protrusion slides along the second recess and the second protrusion slides along the first recess.
