The 9 1/2" Potts-Smith Tissue Forceps with 1 1/2 teeth are designed for precision in handling and manipulating delicate tissues during surgical procedures. The "1 1/2 teeth" refers to the small, serrated teeth on the tips of the forceps, which provide a secure grip on tissues while minimizing the risk of slippage. The 9 1/2" length allows for better reach and control in various surgical environments, making these forceps ideal for use in delicate procedures such as vascular or microsurgery.
