Detailed Description
Minimally invasive surgery (MIS) is well established in gynecological surgery. Compared to laparotomy, MIS is associated with reduced morbidity and quicker recovery. With advancement in laparoscopic technology and techniques, MIS in gynecology has progressed from multi-port to single incision laparoscopic surgery (SILS) and vaginal natural orifice transluminal endoscopic surgery (vNOTEs), thus further reducing morbidity and enhancing recovery.
One of the challenges of MIS is the restriction of the range of surgical movement. To overcome these technical challenges, articulated instruments are increasingly being used. The SIRIUS Endoscope System is a new, fully integrated compact 3D laparoscopic camera system with a disposable single-use flexible tip that can change its viewing direction. The articulated tip has three degrees of freedom, enabling C and S-shaped bending, and providing a wider field of view compared to conventional laparoscopes. This wider field of view is of advantage for SILS and vNOTEs. Presently available commercial systems do not have the same field of view or degrees of freedom.
A first in-human, proof of concept, and early development study of the SIRIUS Endoscope System was done at GHK in 2021 (HKU-GHK IRB 2021-01, ClinicalTrials.gov NCT05048407). The successful completion of 11 of 13 (85%) planned procedures in this sequentially reported, prospective case series, shows that the SIRIUS Endoscope System can be used with indications of safety, and efficacy for intermediate and major MIS laparoscopic procedures in gynecology. The findings have been submitted for consideration for publication.
Based on the outcome of this study, further improvements to the SIRIUS Endoscope System have been made to enhance safety, reliability, and usability. This proposed prospective study is a confirmatory study to evaluate the performance and safety of the SIRIUS Endoscope System in preparation for regulatory approval.

The laparoscopic procedures were done in the usual manner. The only difference was for the study participants, the Sirius System was used in place of the usual conventional laparoscope. All other procedures and instruments including the number of ports remained the same. For every procedure using the Sirius System, a conventional laparoscope was on immediate standby to replace the Sirius System should there be an unanticipated equipment failure so that the procedure could be completed without delay. |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
To evaluate the Performance and Safety of the SIRIUS Endoscope System articulated tip.
Time Frame: Data will be collected during the operation and the analysis will be completed up to 1 month post-operation
|
The performance and safety of the endoscope system will be evaluated based on the outcome of the operation, in terms of patient blood lost and duration of the operation are comparable with the use of other conventional endoscope systems.
|
Data will be collected during the operation and the analysis will be completed up to 1 month post-operation
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
To assess the amount of time of straight and bending positions of SIRIUS Endoscope System articulated tip. To evaluate the events of device deficiency and/or malfunctions of SIRIUS Endoscope System. To evaluate the Safety of SIRIUS Endoscope System
Time Frame: Data will be collected during the operation and it will be completed upon the completion of the operation
|
To assess the effectiveness of the bending function of the SIRIUS endoscope system by capturing the amount of time the SIRIUS endoscope is bent or straightened during the operation.
|
Data will be collected during the operation and it will be completed upon the completion of the operation
