A medical suspension system includes a ceiling plate configured for mounting to a support structure. A fluid can flow through the honeycomb body in a flow direction from the front or anterior end face to the rear or posterior end face. A plurality of source units connected in parallel provide the alternating current to the segment and a current supply conducts electrical energy to the plurality of source units. The linker is selected to increase the specificity, toxicity, solubility, serum stability, or intracellular availability, and promote nucleic acid condensation of the targeted moiety. The cutting rule includes a cutting blade having a cutting edge. A synchronizer is used to synchronize the orientation of the crank handles to avoid the mechanism from jamming during operation and start up.
