Abstract
A surgical device can include a torque limiting device or system. The surgical device can include a rod attached on one end to a rotatable handle and attached on the opposite end to a surgical implement. A first torque limiting element can be connected to the handle, and a second torque limiting element can be operably connected to the rod and surgical implement and releasably engageable with the first torque limiting element. When the first and second torque limiting elements are engaged, rotation of the handle can cause rotation of the rod and surgical implement. When a rotational force that exceeds a predetermined torque limit is applied to the handle, the first torque limiting element can disengage from the second torque limiting element, so that the handle is rotatable without rotation of the rod and surgical implement. The first and second torque limiting elements can be re-engageable so that further rotation of the handle can cause rotation of the rod and surgical implement.
