摘要：A surgical instrument for performing a uterine cervical conization has a pair ofelongated arms pivotally connected together intermediate their ends for scissor-likerelative motion. One arm includes a coextensive probe at one end sized to be insertedthrough the cervical canal. The corresponding end of the other arm secures a cutter inposition forming an acute cutting angle relative to the probe with the apex of the anglelocated adjacent to the distal end of the probe. Locking means is provided for releasablylocking the arms in at least one predetermined relative pivotal position and consequentlythe cutter at a corresponding predetermined cutting angle relative to the probe. In use,the probe is inserted through the cervical canal with the cutter piercing the cervicaltissue. At a sufficient depth, the arms and cutter are locked into position and theinstrument is rotated about the axis of the probe to excise a cone-shaped tissue samplefrom about the mouth of the uterine cervix.
