A New Laparoscopic Multifunctional Instrument Design

Minimally invasive surgery typically requires the use of small instruments that are easily manipulated and have various functions. Our goal is to create, develop, and ultimately obtain a prototype for a novel surgical suction-irrigation device that includes coagulation and neuromuscular stimulation capabilities. The need to achieve accurate hemostasis, particularly during deep pelvic dissection while maintaining suction-irrigation capabilities, served as a valuable motivation for the development of this device. Neurostimulation is necessary in various anatomical contexts, in addition to its coagulation function. Several prototypes were built with exterior diameters ranging from 8 to 5 mm. A series of tests were conducted on pork steaks, and a pathological investigation was carried out using hematoxylin–eosin staining to assess the extent of coagulation. Manual tests demonstrated excellent agility and a high level of effectiveness. The two functions, coagulation and neurostimulation, aid the surgeon in reducing blood loss and accurately pinpointing nerve locations. Hence, this novel prototype has the potential to stimulate the creation of additional equipment that could prove highly valuable in pelvic radical surgery and neuropelveology, where the need for accurate hemostasis and the identification of nerve landmarks are of utmost significance.
