A cervical biopsy device utilizes a biopsy needle having a magnifying lens mounted directly on a cutting sheath. The magnifying lens also acts as a barrier to prevent excessive penetration into the tissue. The components of the biopsy needle, which include a stylet, the cutting sheath and the magnifying lens, may be constructed as a single, disposable unit to eliminate the possibility of blood and/or other fluid contamination when using the biopsy device. In a method of using the biopsy device of the invention, the magnifying lens is used to observe the initial insertion of the stylet and sheath into tissue as well as the cutting and removal of the tissue.

A laparoscopic surgical instrument to perform tubular ligation of the Fallopian tube includes a handle grip to be held by the surgeon. A finger grip is used to slide a body member on a rod fixed to the handle and to squeeze a staple onto the Fallopian tube. A forceps, operated by a button on the handle, pulls up the Fallopian tube and holds a segment of the tube, as a biopsy sample, after it has been severed.
