A surgical gripping instrument, e.g. for gripping and removing intestinal polyps, includes a sheath (60), gripping means (59) at the distal end of the sheath movable with respect to the sheath by a predetermined distance for actuating the gripping means, a support assembly (10) and a slide (30) movable with respect to the support assembly. The slide (30) is connected to at least one of the sheath and the gripping means for movement thereof. In accordance with the invention, means are provided responsive to movement of the slide relative to the support assembly by a distance less than the predetermined distance to cause the gripping means to be moved relative to the sheath by the predetermined distance in order to actuate the gripping means. This enables the throw of the instrument, i.e. the distance the surgeon needs to move his or her fingers, to be reduced to a comfortable level while retaining the desired travel of the gripping means relative to the sheath. <IMAGE> |
