| Abstract: |
Surgical forceps for atraumatically gripping tissue during surgical procedures provides two parallel rows of teeth which interdigitate; they interlock but do not make direct contact. The rows of teeth are separated by a groove which extends into the jaw face below the base of the teeth for the reception of tissue. Elongated members have opposed faces and resilient distal ends, at which ends the members are joined. The members are biased away from each other and require a small finger pressure to move the faces into an abutting relation. When the faces are forced into the abutting relation, teeth on the proximal ends interdigitate and positively grip, but do not puncture or otherwise injure, the tissue.

What is claimed is:
1. Surgical forceps for atraumatically gripping tissue comprising a pair of opposed elongated members having confronting faces, said members including a rear resilient section and said members joined at said section such that said members are normally biased away from each other, said faces forcible into generally abutting relation with application of a relatively small amount of pressure, the forward ends of said faces comprising two parallel rows of pyramidal teeth separated by a groove which extends into said face below said teeth, said teeth on the opposed members being identical but longitudinally interdigitating when said faces are in said aubtting relation, said teeth adapted for use in surgical procedures requiring the gripping of very thin layers of tissue, said tissue when gripped, tending to fill the spaces between the teeth in an undulated configuration and also tending to fill said groove, whereby the tissue may be positively but atraumatically gripped without puncture or injury.
