Combination Instruments for Endoscopic Surgery

With a routine laparoscopic cholecystectomy, we prefer the combination of blunt and sharp dissection when the gallbladder is dissected. To avoid the need for instrument changes, we have designed a combination instrument that allows the integration of a hook for dissection [1]. When the hook is pulled backward into the shaft, blunt dissection is possible; when the hook is moved forward, a sharp dissection with high frequency can be performed easily.

Figure 12.13 demonstrates the function of rinsing and suction using the laparoscopic combination instrument.
