Abstract
A biological forceps device is disclosed for the taking of tissue samples from a body. The biopsy forceps device comprises a flexible main coil having a distal end which is stiffer than the majority of the coil, a pair of opposed jaws hingedly disposed on the distal end of the coil, and an actuator having a distal end coupled to the hingedly disposed jaws for effecting articulation of the jaws. Preferably, shrink wrap tubing is placed on the distal end of the coil and acts as the stiffening agent thereof. A stiffer distal end permits the practitioner to press the jaws deeper into the tissue and reduces the jump experienced at the distal end when the coils go from a state of tension (jaws open) to a state of compression (jaws closed), so that a better sample can be obtained.
