ABSTRACT:
Multi-pronged spring-loaded laparoscopy instruments are provided for use in tubal sterilization, ovarian mobilization and biopsy. The instruments include three or four expandable prongs for holding tissue in a stable position. The instrument may be provided with a plug for access to an inner biopsy channel or central bore for facilitating ovarian biopsy. A slotted bushing may be provided with offset apertures to enable the surgeon to hold the prongs in preselected positions without exerting pressure on the handle of the instrument. When desired, the instrument may be provided with a manually remote-controlled cutting edge at the forward tip of the instrument to resect a segment of the coagulated tube during tubal sterilization.
