“…Three approaches to robotic TRUS-guided RALP have been investigated. The first system, proposed by Han and colleagues, 59 enables the surgeon to view a 3D reconstruction of the prostate gland on a screen separate from the console view, aiding intra operative planning. Secondly, Hung et al 60 demonstrated the use of a ViKY® robotic TRUS-manipulated system (EndoControl® Medical, Grenoble, France) in which the ultrasound scan was able to identify biopsy-proven capsule-abuttin g lesions in 50% of patients (n = 10).…”

Robotic prostatectomy is a common surgical treatment for men with prostate cancer, with some studies estimating that 80% of prostatectomies now performed in the USA are done so robotically. Despite the technical advantages offered by robotic systems, functional and oncological outcomes of prostatectomy can still be improved further. Alternative minimally invasive treatments that have also adopted robotic platforms include brachytherapy and high-intensity focused ultrasonography (HIFU). These techniques require real-time image guidance--such as ultrasonography or MRI--to be truly effective; issues with software compatibility as well as image registration and tracking currently limit such technologies. However, image-guided robotics is a fast-growing area of research that combines the improved ergonomics of robotic systems with the improved visualization of modern imaging modalities. Although the benefits of a real-time image-guided robotic system to improve the precision of surgical interventions are being realized, the clinical usefulness of many of these systems remains to be seen.

“…The outline of the kidney can be approximately delineated in the elastogram, as well as the contrasting internal collecting system. In addition to the use with kidneys, studies have shown that B-mode and strain imaging are useful for prostatectomy [6], and the system described in this paper could easily be applied to this procedure. The surgeon would also have the option to combine information from a trans-rectal ultrasound transducer and the da Vinci controlled transducer.…”

Abstract.Although robotic surgery has addressed many of the challenges presented by minimally invasive surgery, haptic feedback and the lack of knowledge of tissue stiffness is an unsolved problem. This paper presents a system for finding the absolute elastic properties of tissue using a freehand ultrasound scanning technique, which utilizes the da Vinci Surgical robot and a custom 2D ultrasound transducer for intraoperative use. An external exciter creates shear waves in the tissue, and a local frequency estimation method computes the shear modulus. Results are reported for both phantom and in vivo models. This system can be extended to any 6 degree-of-freedom tracking method and any 2D transducer to provide real-time absolute elastic properties of tissue.

“…Similarly, the capacity of intraoperative transrectal ultrasound to visualize functionally important structures, such as the urinary sphincter or the neurovascular bundles, has been demonstrated and the interest of including such images in the laparoscopy images is becoming clear. Among the several conceivable approaches is the one described in [20], which proposes pairing a specific robot to hold the endorectal catheter with a DaVinci ® system. Further development of this type of approach is certain; it will be facilitated or demanded by the appearance of new miniaturized ultrasound sensors that can be used, for example, in arthroscopic procedures [21], or by the widespread use of new ultrasound imaging modalities, such as elastography.…”

In standard practice, the surgeon perceives multiple types of data (visual, tactile, auditory, even olfactory information), decides at each moment the optimal strategy to pursue, and acts in accordance with this strategy. Here we refer to as a ''surgical robot'' any system able to use digital data to help the surgeon work physically on the patient. Every surgical robot therefore uses sensors, its own capacity to process the information they collect, and instruments. We will use this common framework to describe and propose a classification of the current robots and to discuss their future prospects.The sources of information used by the robots in clinical practice today are, on the one hand, medical images, both pre-and intraoperative, and on the other hand, images and measurements of position, of three-dimensional (3D) shapes, and of force.Historically, beginning in 1988, X-ray CT was the first imaging method used to plan robotic stereotactic neurosurgery procedures [1], which were then performed in the CT scanner room. The superior performance of magnetic resonance imaging (MRI) for brain imaging, as well as the fact that an operating room is much better adapted to surgery than the scanner room, led us to suggest that stereotactic neurosurgical procedures should be guided by a robot that can use intraoperative MRI [2] and radiography (Fig. 1). Ultrasound subsequently appeared to be a very useful source of images for guiding surgery, including procedures involving bones [3]. These sources of images have since been widely used by surgical robots.Other sensors, initially developed for computer vision applications, now play an important role in these robots. Three-dimensional position sensors or trackers (also called 3D localizers), for example, are an essential component of all the surgical navigation systems presented in Section Action: classification of surgical robots. Their principle is to make
