Abstract
Abstract A surgical instrument is provided particularly suited for use in circumcision operations comprising a clamping and holding member adapted to be readily formed of molded plastic material and especially constructed for use in circumcision operations involving the use of conventional hospital instruments such as a probe, scalpel, hemostat, and the clamping and holding member comprising side members pivotally connected at their ends by a novel trunnioned hinge joint. In a preferred form the instrument includes in combination with the clamping and holding member a cutting member pivotally mounted on the clamping and holding member and guided in cooperative operating position, and which instrument is sufficiently inexpensive so that it can be discarded after the end of the operation thereby obviating the need of sterilization for reuse.
