Robotic Deformation Tracking Validation

We used the dVRK system to conduct all the validation experiments (Fig. 2). This system consists of mechanical parts from da Vinci Classic Surgical System donated by Intuitive Surgical Inc., and open source electronics and software (cisst/SAW libraries) developed by researchers at Johns Hopkins University.¹² This surgical robot has three Patient Side Manipulators (PSMs), one Endoscopic Camera Manipulator (ECM), and two Master Tool Manipulators (MTMs). In the following evaluation experiments, we used two PSMs holding the ProGrasp Forceps (Intuitive surgical, Inc., California, USA) for active manipulation of the DT, one PSM holding a Large Needle Driver (Intuitive surgical, Inc., California, USA) to manipulate an 18 Gauge needle (simulating the cryoprobe), and an endoscope mounted on the ECM for obtaining the image feedback (Fig. 2).
For measuring the deformation of the DT (i.e., image displacements of the feature points), we implemented a visual tracker algorithm with the Optical Flow package of the OpenCV library,³ which uses Lucas-Kanade algorithm.² We developed our control algorithm using the cisst/SAW libraries in C++ and Matlab (MathWorks, Inc.) and used Matlab-ROS bridge¹⁷ to communicate between these environments in real-time.

Robotic vs Open Partial Nephrectomy

Check if the same lab product or an alternative is used in the 5 most similar protocols

After approval by our local Institutional Review Board (ID: 3876), all consecutive patients undergoing PN at our institution from January 2014 to December 2019 were recorded in a prospective database and included in this study after signing informed consent. Conversion to radical nephrectomy for oncological reasons was an exclusion criterion. Prospectively collected patients’ data were retrospectively analyzed. OFFC-OPN was already a consolidated technique at our center applied to the vast majority of cases, while RAPN was introduced in 2014, starting from the beginning with an off-clamp approach. The surgical technique adopted for RAPN followed a standardized four-arm transperitoneal six-port approach, using a 30° lens, a fenestrated bipolar forceps, monopolar curved scissors and a ProGrasp™ forceps (Intuitive Surgical Inc., Sunnyvale, CA, USA) with da Vinci SI^® (Intuitive Surgical Inc., Sunnyvale, CA, USA), from 2014 to December 2015, or da Vinci XI^® (Intuitive Surgical Inc., Sunnyvale, CA, USA), from January 2016. In order to avoid bias related to the surgeon’s learning curve, the first 20 consecutive OFFC-RAPN patients were excluded. The majority of OPN and all RAPN procedures included in the present study were performed by the same expert senior surgeon. However, all OPN procedures were performed by three expert senior surgeons.

Robotic-Assisted Prostatectomy Protocol

Once the patient was intubated and properly secured in a supine position, the lower abdomen, external genitalia and upper thigh were disinfected and draped. A Foley catheter was then placed in a sterilized manner, which would be manipulated by the bedside assistant during the operation. Pneumoperitoneum was established with the Hasson open technique and maintained at 12 mmHg. A standard W configuration of the camera port, three robotic ports (for coupling with Hot Shears™ monopolar [first arm; Intuitive Surgical], Maryland bipolar forceps [second arm; Intuitive Surgical], ProGrasp™ forceps [third arm; Intuitive Surgical] and two large needle drivers [first and second arms; Intuitive Surgical]) and a 12‐mm assistant port was used, with an additional 5‐mm assistant port placed four fingerbreadths below the costal margin and between the camera port and the right‐hand robot port (Fig. 1). The patient was then placed in a 15° Trendelenburg position. The robotic cart was docked in the midline caudal position as with other transperitoneal approaches.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
