Abstract
A contoured forceps handle is presented having a first arm with a contoured surface and a second arm with a contoured surface to provide for rotation in the hand of a user. The forceps handle may be used with a forceps or may have tips attached. Contoured forceps onlays are also presented that may be attached to forceps.

A surgical forceps comprising:
- a forceps handle having a first metal arm attached to a second metal arm, the first metal arm having a first distal grasping surface and the second metal arm having a second distal grasping surface configured to grasp tissue;
- wherein the first metal arm has a first contoured surface material and the second metal arm has a second contoured surface material, the forceps handle being configured to be held in a hand of a user such that the hand of the user can apply a compressive force in opposition to a spring force separating distal ends of the first metal arm and the second metal arm to reduce a distance between the first distal grasping surface and the second distal grasping surface, wherein the first contoured surface material and the second contoured surface material can be grasped by the hand of the user, the first contoured surface material and the second contoured surface material each having a rounded distal trough surface with elastic textured surface features positioned to prevent fingers of the user from sliding distally toward tips of the forceps, the rounded distal trough surface having a reduced lateral diameter that is positioned between a larger distal portion surface and a rounded larger central portion surface, wherein the rounded larger central portion surface extends to a rounded proximal trough surface, each surface being shaped at least partially around a longitudinal axis of each metal arm;
- and
- wherein the first contoured surface material comprises a first gripping surface positioned on the first metal arm that extends into the rounded distal trough surface and the second contoured surface material comprises a second gripping surface positioned on the second metal arm that extends into the rounded distal trough surface having the elastic textured surface features wherein the elastic textured features are configured to provide tactile feedback to the user such that the user can manually manipulate the forceps while grasping tissue without damaging the tissue.

A surgical forceps comprising:
- a forceps having a first metal arm and a second metal arm that are connected at a proximal portion of the forceps such that a user's hand can apply a compressive force to reduce a distance between distal ends of the first metal arm and the second metal arm in opposition to a spring force separating the distal ends of the first metal arm and the second metal arm;
- a first forceps handle onlay having a first contoured top surface having a rounded shape about a first metal arm longitudinal axis;
- a second forceps handle onlay having a second contoured top surface having a rounded shape about a second metal arm longitudinal axis;
- and
- wherein the first metal arm, the second metal arm, the first contoured top surface and the second contoured top surface form a composite forceps handle that includes a rounded distal trough surface having a reduced lateral diameter on each contoured top surface that each have an elastic textured surface region positioned to prevent fingers of the user from sliding distally towards the distal ends, the elastic textured surface region positioned between a larger lateral diameter rounded distal portion and a larger lateral diameter rounded central portion and a rounded proximal trough surface extending along the top surface of each onlay and further wherein the first forceps handle onlay is attached to the first metal arm, the second forceps handle onlay is attached to the second metal arm, and the rounded proximal trough surface extends around the proximal portion of the forceps wherein the elastic textured surface region on each onlay is configured to provide tactile feedback to the user such that the user can manipulate the forceps while grasping tissue without damaging the tissue.

A method of assembling a surgical forceps comprising:
- fabricating a forceps handle having a first metal arm and a second metal arm connected at a proximal portion of the forceps handle and configured to compress together at respective distal ends to grasp tissue;
- fabricating a first surface element and a second surface element;
- and
- attaching the first surface element to the first metal arm and attaching the second surface element to the second metal arm such that the forceps handle includes an outer contoured surface configured to be held in a hand of a user such that the user can rotate the forceps while grasping an object with the forceps, the outer contoured surface including a rounded distal trough surface with a reduced lateral diameter on each surface element having an elastic textured surface region that compresses in response to manual pressure in opposition to a spring force separating the distal ends of the first metal arm and the second metal arm to indicate a tactile gripping pressure to the user, the elastic textured surface regions being positioned to prevent fingers of the user from sliding distally toward the distal ends of the metal arms, the elastic textured surface region positioned between a rounded larger lateral diameter distal portion surface and a rounded larger lateral diameter central portion surface extending along a longitudinal axis of each arm such that a distance between the distal ends of the first metal arm and the second metal arm can be manually compressed by the user's hand to sense grasping the tissue with the elastic textured surface regions at the tactile gripping pressure without damaging the tissue and wherein a rounded proximal trough surface extends along each surface element around the proximal portion of the forceps handle.
