Postmarketing Analysis of a Novel, Cordless Ultrasonic Dissector

Abstract

Introduction Tissue dissection and vessel sealing is performed using a variety of energy sources and surgical devices. We describe the postmarketing analysis of a cordless ultrasonic dissector and vessel sealer in a series of general and gynecological procedures. Methods Patients were prospectively screened and consented for participation. Data collected included demographics, device activations/seals and failures, and patient complications. Surgeons were surveyed following each case. Data was analyzed using standard statistical methods. Results A total of 110 patients were consented and participated in the study. The most frequently performed procedures were bilateral salpingo-oophorectomy (n = 48) and total laparoscopic hysterectomy (n = 36). Mean age was 54.2 years and 79.2% were female. The most frequent number of device activations per case was between 26 and 50 (36.6%). Five failed seals occurred out of 4858 total estimated seals (0.11%). Failed seals were felt to be due to thickened, scarred tissue not amenable to device compression. There were no patient intraoperative complications related to the device itself. Overall, surgeons felt the device was extremely easy to use (97.6%) and no visual obstruction due to steam from the device was encountered (95%). Ninety-five percent of surgeons felt the device was beneficial for soft tissue dissection and vessel sealing. Conclusion Sonicision is safe and effective for use in dissection of soft tissues and vessel sealing in a variety of laparoscopic and open procedures. In this study, there were no complications related to the device itself. The remarkable cordless design of this device enhances its ease of use with overall excellent effectiveness.

“…Also, it is well known that the presence of all kinds of devices and cables makes a laparoscopic arena more crowded than an open surgery [ 9 ]. Connection with cables greatly restricts the use of laparoscopy in environments outside the operating room and limits the mobility of the laparoscope, potentially contaminates the operating area, and can cause accidents [ 4 , 5 ]. Although the cornerstone of laparoscopic instruments has already been established and fixed, emerging technologies enable laparoscopy to develop in the direction of small volume, intelligence, and ergonomics [ 8 ].…”

“…A rigid laparoscope is composed of a long rod lens, camera, camera cables, and optic fibres. Wired connections of the light source and other devices prolong the preoperative setup time and occupy a large amount of space in the operating room [ 4 ]. The presence of cables and wires increases the risk of operating area contamination and limits the mobility of the instrument [ 5 ].…”

“…The presence of cables and wires increases the risk of operating area contamination and limits the mobility of the instrument [ 5 ]. The multiple cables can tangle together in the operative field, leading to the inconvenience of manipulation for operators and increased safety hazards such as conflagration [ 4 ]. In addition, optic fibres can be easily damaged by inadvertent dropping or frequent pulling and causing declined efficiency of lightening [ 6 ].…”
