Официальное название
Platform Construction and Clinical Application of 5G Technology for Remote Operation of the R-One™ Robot in Percutaneous Coronary Intervention
Обзор
Patients with coronary artery disease requiring PCI treatment were enrolled in the study. All patients underwent PCI with the robotic R-OneTM System (R-One Vascular Robotics, Cathbot). The system was designed for coronary PCI and consists of 2 major components: the command unit and a bedside robot. The command unit is a radiation-shielded, mobile workstation that was positioned in the corner of the catheterization laboratory. The interventional cardiologist sits at the command unit and remotely performs the PCI using the console joysticks. Commands from the control console are delivered as electrical signals along a communication cable that runs from the control console to the robotic drive, on which a sterile cassette is placed. The cassette, which is loaded with the robot and connected to the guiding catheters, imposes axial and rotational forces on the intracoronary devices. Fluoro-scopic, electrocardiographic, and hemodynamic images are "slaved" to the duplicate monitors inside the cockpit, enabling visualization from a closer distance. After completion of diagnostic angiography, the guiding catheter was positioned at the ostium of the coronary artery and connected to the disposable cassette on the robotic drive. The guidewire was loaded into the cassette before starting the robotic-enhanced PCI. The treatment plan is decided by the doctor according to the patients' situation. All intracoronary devices were to be manipulated exclusively by the robotic system, with bailout to manual conversion when needed. The primary endpoints were clinical procedural success and device technical success. The necessary sample size for testing the endpoint of clinical and technical procedural success was calculated on the basis of the target value. The statistical analysis results show that the lower limit of the 95% confidence interval of the clinical success rate and the technical success rate of the operation is greater than 90% of the target value, and the invalid hypothesis is rejected. Both primary endpoints had to be met for the study to be declared successful. Data were analyzed on an intention-to-treat basis. Standard summary statistics were calculated for all patient and study outcome variables. Continuous variables were summarized using estimated means, standard deviations, minimums, maximums, medians, and interquartile ranges. Categorical data were summarized using frequencies, percentages, and 95% confidence interval.
Подробное описание
1. Purpose To evaluate the effectiveness and safety of 5G-enabled remote control of the R-OneTM vascular interventional navigation control system for percutaneous coronary interventions. 2. Research design A prospective, multicenter, exploratory clinical trial. Subjects who met the inclusion criteria and did not meet the exclusion criteria were enrolled into the clinical study, and the subjects are randomly grouped by using the interactive web response system (IWRS) applet (MedLand Centralized Randomization Management System). The surgeons completed the robotic-assisted surgical operation using the investigational device during cardiovascular PCI treatment. The investigator is also required to evaluate the performance of the investigational device during the procedure and ultimately determine the safety and efficacy of its clinical application. 3. Device The investigational device was R-One Vascular Interventional Navigation Control System developed and produced by Robocath, and was composed of a platform (instruction unit, robot, support joint arm), a consumable set (cartridge, instruction unit protective sleeve), and a remote workstation. 4. Scope of Trial The subjects scope of the clinical trial: Patients requiring cardiovascular PCI. 5. Experimental Procedure Information of all the patients who have signed the Informed Consent Form and actually pass the screening will be registered in the screening/enrollment log sheet. If a subject is excluded from the trial, the investigator should specify the reasons for screening failure. If a subject is enrolled in the trial but does not use the investigational device, the reason should also be recorded.
All subjects enrolled in the trial will be given a corresponding enrollment number.
72-hour pre-operative collected ECG, cardiac enzyme, and concomitant medication records.
Operation day visit The investigator is also required to complete the cardiology robot-assisted surgical treatment using the investigational device and record the procedure, LED Scale, SME Scale, and device Performance Evaluation Pre-discharge visit The investigator shall collect the blood test, creatinine, ECG. cardiac enzyme, concomitant medication records.
1 month post-operative visit The investigator shall collect the concomitant medication records.
Application method of the investigational device Subjects who meet the inclusion criteria and do not meet the exclusion criteria will be enrolled in the clinical study and the surgeon will complete the therapeutic treatment on the subject while performing the cardiology PCI procedure.
The investigational devices should be used by investigators respectively during the surgical treatment according to product instructions. Surgeons who would participate in the trial and use the study device should have completed at least 80 PCI procedures and need to be trained and supervised by the physician who completed the animal experiments using the investigational device.

Robot-assisted treatment duration = time when the robot finish moving the guidewire away from the coronary vessel - time when the robot starts manipulating the guidewire. 3. Radiation exposure to the patient Evaluation Method: Measure and record dose exposure by angiography (DSA) 4. Radiation exposure to surgeons Evaluation Method: Detect radiation through radiation dosimeters. Two dosimeters will be used simultaneously during the procedure. One is placed on the operating table and the other is worn by the surgeon to measure the radiation dose exposed to the surgeon. Both dosimeters will be calibrated once a day before use and reset to zero before each PCI procedure. Radiation readings from the dosimeter will be recorded when the first guidewire is inserted into the vessel and the last guidewire is pulled out of the vessel. 5.
