Abstract
Abstract This surgical instrument has a clamping and holding member of special construction especially suited for use in circumcision operations involving the use of conventional hospital instruments such as a probe, scalpel, and hemostat, for completing the circumcision operation, while in the preferred form the instrument will involve the use in combination of two main portions, with one of these being the clamping and holding member, and the other a cutting member, with the two members pivotally connected together and guided in cooperative operating position, and when the two main portions are principally formed of plastic, same can be discarded at the end of the operation without need of sterilization for reuse.
