ABSTRACT:
There is disclosed herein a medical instrument in the form of an elongated member having at its distal end a plug structure with a removable section and having at its proximal end a manually operable device for causing a predetermined motion of the removable section. The medical instrument is used by insertion of the distal end into a body cavity for performing a medical procedure. In a preferred form, the medical instrument comprises an electrode assembly wherein the plug structure at the distal end includes one or more electrodes useful, for example, in monitoring fetal heartbeat. In an alternative form, the plug structure at the distal end includes a surgical tool for removing tissue for enabling a biopsy to be performed. In either instance, the plug structure at the distal end includes a stationary member and a movable support for causing either an electrode, or the surgical tool, to pivotally move away from and toward the stationary member for engaging tissue. The manually operable device at the proximal end may include a ratchet and cam assembly which operates through a wire or other elongated connector member to cause pivotal movement of the movable support member.
