DISPOSITIF DE PINCEMENT AMELIORE, NOTAMMENT DU TYPE PINCE A BIOPSIE

摘要

The invention concerns biopsy forceps comprising two jaws (9) capable of being spaced and brought together when a manoeuvring element (2) slides in a sheath (3). The two jaws (9) are articulated on an attachment (20) fixed on the manoeuvring element end. The jaws (9) are partially housed in a passage of the sheath (3) end. They are guided by a rod (8) when they are spaced and by the sheath (3) end surface when they are brought together. The transverse element (8) comprises a passage (26) with an axis substantially parallel to the sheath (3) axis for passing an auxiliary instrument (23) between the jaws (9).
