  • Patent number: 4945920
    Abstract: The biopsy forceps comprises a handle portion having a distal end, an elongate tubular torqueable and formable body assembly and a forceps assembly. The tubular body assembly includes a coil spring guide wire having a proximal portion and a distal portion extending between the handle portion and the forceps assembly. A first tubing or covering over the proximal portion of the coil spring guide wire extends from the handle portion towards the forceps assembly. The first tubing has a distal end and a proximal end, and has a high resistance to twisting and a high transmission of torque applied thereto. A second tubing or covering of formable material is received over and tightly engages the distal portion of the coil spring guide wire, and imparts a high formability to the distal portion of the coil spring guidewire. The second tubing or covering has a distal end, a proximal end and extends rearwardly from the forceps assembly to a distal end of the high torque transmitting first tubing or covering.

  • Patent number: 4815476
    Abstract: A biopsy forceps device comprises a handle portion an elongate flexible hollow body portion having a proximal end coupled to the handle portion and a distal end. A forceps assembly is coupled to the distal end and includes a pair of forceps. A stylet control wire in the body portion is coupled to the pair of forceps at the distal end of the body portion. A locking hub assembly is coupled between the handle portion and the proximal end of the body around the stylet/control wire and includes a locking hub and locking means for locking the stylet/control wire in an axial position thereof to the locking hub assembly relative to the body portion upon rotation of the locking hub.
