Abstract
A surgical instrument for improved viewing of a surgical site by a surgeon from the perspective of a working element of the instrument. The surgical instrument includes an elongated shaft with a distal operating portion extending at least about one-fourth of the length of the shaft. A working element is disposed on a distal end of the shaft. An elongated fiberoptic assembly is included, having image fibers with a distal end with an objective lens for defining a predetermined field-of-view, and a coupling device at a proximal end for coupling same to a viewing system. A mounting device is utilized for mounting the fiberoptic assembly to the shaft along the length of the distal operating portion thereof. The distal end of the image fibers is positioned with a predetermined portion of the working element within the field-of-view of the fiberoptic assembly.
