There is disclosed a flexible biopsy forceps device for extracting tissue samples from a patient. The forceps device includes a long flexible sheath having a cable extending therethrough, a jaw assembly connected at one end of the cable and a handle assembly attached at the other end of the cable. The handle assembly includes a spool slidably mounted on a shaft connected to the cable and sheath in such a way that movement of the spool handle results in movement of the cable with respect to the sheath to open and close the jaws. A spool insert is provided which has two portions which fit together locking the end portion of the cable therebetween. The spool insert slides into an axial passageway in the spool and interlocks with the spool in such a way that it is irreversibly locked therewith. The jaw assembly includes a trocar which is locked with the jaw assembly using a tongue-in-groove assembly.
