Surgical clamp pad with interdigitating teeth

A surgical clamp member for attachment to a jaw of a jaw-type surgical clamping device, the clamp member comprising:

• a base member having attaching protrusions adapted to be received into reciprocal recesses in the jaw for attaching the clamp member to the jaw;
• a resilient pad secured to the base member, the pad having gripping protrusions extending therefrom for engagement with a vessel or other tissue;
• and
• through holes extending across the pad between the base member and protrusions.

A surgical clamp member for attachment to a jaw of a jaw-type surgical clamping device, the member comprising:

• an attaching structure for attaching the member to the jaw;
• a resilient pad secured to said attaching structure, the pad having protrusions extending therefrom for engagement with a vessel or other tissue;
• and
• holes extending across the pad between the attaching structure and protrusions, wherein the holes open to at least one side of the pad.

A method of manufacturing a resilient pad for attachment to a jaw of a jaw-type surgical clamping device, the pad having a backing surface and a gripping surface opposite thereof for engagement with a vessel or other tissue, and holes extending across the pad between the backing surface and the gripping surface and opening to at least one side of the pad, the method comprising the steps of:

• (a) providing a mold having first and second sections defining a mold space, wherein at least one of the sections includes rods extending into the mold space;
• (b) injecting an elastomer into the mold space;
• (c) allowing the elastomer to harden to form the resilient pad;
• and
• (d) removing the formed pad from the mold.

A method of manufacturing a resilient pad for attachment to a jaw of a jaw-type surgical clamping device, the pad having a backing surface and a gripping surface opposite thereof for engagement with a vessel or other tissue, and through holes extending across the pad between the backing surface and the gripping surface, the method comprising the steps of:

• (a) providing a mold defining a mold space, wherein the mold includes a series of molding pin holes for receiving molding pins;
• (b) inserting molding pins into the molding pin holes such that portions of the pins extend through the mold space;
• (c) injecting an elastomer into the mold space;
• (d) allowing the elastomer to harden to form the resilient pad;
• (e) removing the molding pins from the mold;
• and
• (d) removing the formed pad from the mold.
