The da Vinci Surgical System versus the Radius Surgical System  [PDF]
Norihiko Ishikawa, Go Watanabe, Noriyuki Inaki, Hideki Moriyama, Masanari Shimada, Masahiko Kawaguchi
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.37070
Abstract: Objective: Kanazawa University introduced the da Vinci surgical system and the Radius surgical system. In this study, we compared the advantages and disadvantages of each system. Methods: The da Vinci system is a master-slave tele-manipulation system, which provides hi-resolution 3D images. The Radius system is pair of hand-guided surgical manipulators. In this study we focus on the operability of both instruments rather than their 3D optical systems. Results: The Radius was originally developed specifically focused on ligation and suturing with suture sizes bigger than 4-0, it is more effective, less expensive compared with the da Vinci. Although the da Vinci system is bulky, it allows surgeons to perform endoscopic surgeries only if ports are properly placed to prevent each arm from colliding with the other arms. A crucial difference between the Radius and the da Vinci is not limited to anastomose small vessels but is extended to multidirectional dissection. Currently, the cost including initial investment is the biggest issue; however, the da Vinci is absolutely necessary to implement delicate cardiac surgeries endoscopically and less-invasively. Early approval of robotic surgery by the government is urgently required in Japan. Conclusions: Although both the da Vinci and the Radius have endoscopic instruments with a multi-degree of freedom, applications need to be differentiated depending on the procedures and indications. Therefore, it can be clearly said that these unique innovative systems will never compete against each other.

Mélanie Frigenza, Jér?me Delotte, Eric Fontas, Daniel Benchimol, André Bongain, Jean Breaud
Open Journal of Obstetrics and Gynecology (OJOG) , 2013, DOI: 10.4236/ojog.2013.32054

Background: To investigate the learning curve of “robotic surgery” versus “conventional laparoscopy” in two trials of the FLS program in a population of medical students with no experience in laparoscopy. Methods: A prospective trial. Students, all novices in training and surgical practice, were randomized into 2 groups: the “traditional laparoscopy” group and the “robotic assistance” group. Students were evaluated during two tests from the FLS: peg transfer and intracorporeal knot tying. Results: The median laparoscopic knot completion time was significantly lower in the “robotic surgery” group (p = 0.038). Conclusions: Robotic assistance training in neophytes is effective in improving the completion time of laparoscopic knots.

Gynecological Surgery and the Robot  [PDF]

Engineering (ENG) , 2014, DOI: 10.4236/eng.2014.62009

As the only robotic device with FDA approval for gynecological surgery, the da Vinci? Surgical System dominates robot-assisted surgery in the field. Benefits to the Surgeon include decreased risk of neck and back injury secondary to improved ergonomics. However, patients benefit greatly due to decreased length of stay, decreased blood loss and analgesic requirements. Unfortunately the initial economic impact of purchasing and maintaining a robot is great but must be balanced with the potential savings from reduced length of stay and earlier return to normal activity. This article looks at the indications for robot-assisted surgery in gynecology. Assessing the efficacy of this modality compared to both straight stick (Laparoscopy) and open procedures. We discuss the impact and implications for surgical training imposed by robotic surgery. Furthermore, we assess the safety of robotic surgery from both the surgeons prospective and as a surgical modality.

Advances in Historical Studies (AHS) , 2013, DOI: 10.4236/ahs.2013.22007
Abstract: Leonardo da Vinci (1452-1519) is perhaps overrated for his contributions to physical science, since his technical approach. Nevertheless important components concerning practical problems of mechanics with great technical ability were abounded. He brought alive again the Nemorarius’ (fl. 12th - 13th century) tradition and his speculations on mechanics, if immature made known how difficult and elusive were the conceptual streams of the foundations of science for practitioners-artisans. Leonardo also had an interesting and intense relationship with mathematics but merely unhappy insights in his time. The meeting with Luca Bartolomeo de Pacioli (1445-1517) was very important for da Vinci since proposing stimulating speculations were implemented, but they were not definitive theoretical results. In this paper historical reflections notes on mechanics and mathematics in da Vinci and his relationships with Pacioli are presented.
La Utilización Temprana de Herramientas Tafonómicas: Leonardo da Vinci y Florentino Ameghino

Serie correlaci?3n geol?3gica , 2008,
Abstract: we present a synthesis about the interpretation of the biblical deluge carried out by two important historic personages separated by four centuries: leonardo da vinci and florentino ameghino. these authors used in your interpretations tools that pertain to the modern taphonomic theory. da vinci, within the framework of the renaissance, very far still of the basic development of earth sciences, studied the autochthony, transport and disarticulation of fossil shells from monferrato (italy). ameghino, under a evolutionist and gradualist paradigms, analyzed the configuration of fossil assemblages from the "pampean formation". both concluded that the analyzed evidence does not correspond with the description of a catastrophic event as the universal biblical deluge.

Abstract: This paper seeks to analyse the feminine in the “Da Vinci Code”, a novel written by Dan Brown, whose the mean theme is permeated by issues relating to the feminine, linking it to the art and religion.We use the notion of female seized by psychoanalysis, to take this reading of the book, placing the efforts of the author in his attempt to unravel the mysteries of the sacred feminine.
Robotic assisted minimally invasive surgery

Journal of Minimal Access Surgery , 2009,
Abstract: The term "robot" was coined by the Czech playright Karel Capek in 1921 in his play Rossom′s Universal Robots. The word "robot" is from the check word robota which means forced labor.The era of robots in surgery commenced in 1994 when the first AESOP (voice controlled camera holder) prototype robot was used clinically in 1993 and then marketed as the first surgical robot ever in 1994 by the US FDA. Since then many robot prototypes like the Endoassist (Armstrong Healthcare Ltd., High Wycombe, Buck, UK), FIPS endoarm (Karlsruhe Research Center, Karlsruhe, Germany) have been developed to add to the functions of the robot and try and increase its utility. Integrated Surgical Systems (now Intuitive Surgery, Inc.) redesigned the SRI Green Telepresence Surgery system and created the daVinci Surgical System classified as a master-slave surgical system. It uses true 3-D visualization and EndoWrist . It was approved by FDA in July 2000 for general laparoscopic surgery, in November 2002 for mitral valve repair surgery. The da Vinci robot is currently being used in various fields such as urology, general surgery, gynecology, cardio-thoracic, pediatric and ENT surgery. It provides several advantages to conventional laparoscopy such as 3D vision, motion scaling, intuitive movements, visual immersion and tremor filtration. The advent of robotics has increased the use of minimally invasive surgery among laparoscopically naοve surgeons and expanded the repertoire of experienced surgeons to include more advanced and complex reconstructions.

Norihiko Ishikawa, Masahiko Kawaguchi, Hideki Moriyama, Go Watanabe
Surgical Science (SS) , 2012, DOI: 10.4236/ss.2012.32015
Abstract: Introduction: Single Incision Laparoscopic Surgery (SILSTM) has been developed as a less invasive laparoscopic surgery. On the other hand, robotically assisted surgical technology has offered new options for minimally invasive surgery. In this study, we report a new surgical technology to perform SILS using the da Vinci S surgical system (Intuitive Surgical Inc., Sunnyvale, CA). Materials and Surgical Technique: A porcine liver with gallbladder was placed on an endoscopic surgery trainer, and a 25 mm incision was made for one robotic camera and two instruments at the umbilicus position. Both instruments were crossed while preventing them from colliding with each other, and Robot-assisted single-incision cholecyctectomy was perfumed. Discussion: This technique is expected to contribute to the development of a number of procedures in the future.
America’s Birth Certificate: The Oldest Globular World Map: c. 1507  [PDF]

Advances in Historical Studies (AHS) , 2015, DOI: 10.4236/ahs.2015.43019
Abstract: In 2012, a woodcut print for a c. 11 centimeter globe was discovered in an ancient volume in the University Library in Munich. This pivotal 1 million US$ globular world map, which only differs marginally from four other extant woodcut copies, attracted worldwide media attention. This discovery ignited the search for the date and the origin of an enigma in the form of an intricate secretive small Renaissance map. The aforementioned had been acquired inserted in a French adapted and unauthorised copy of the Introduction to Cosmography dated 1507 and printed in Lyon. The son of a Dutch American immigrant from Flusching, H. C. Kalbfleisch bought it in Paris in 1881 and brought it to New York. The author offers key evidence that this secretive map is an important misinterpreted and misdated cultural historical prototype which antedates five later woodcut copies: gores in Munich UB, Minnesota-Hauslab, Christie’s, SL Munich and Offenburg. He proves that its size and scale are inspired by a calculation of Leonardo da Vinci as described in one of his Codices, and applied on the 1504 Ostrich Egg globe discovered in London 2012. The research methodology used is stemmatics as developed by the German scholar K. Lachmann applied on ancient maps and the evaluation of the scientific aspects and architectural, historical and artistic design. Evidence was offered that the Introduction to Cosmography printed in France in which the engraved map was loosely inserted, together with two additional copper engravings, was printed prior to March 1508. The map research leads to the Benedictine monk and German cartographer, globe constructor and astrologist Donnus Nicolaus Germanus. The latter was the first who constructed a terrestrial and a celestial globe for the library of the Pope Pius IV. The two additional copper engravings lead to the Dutch born medical doctor and astrologer Guillelmus de Wissekerke, supplier of astrological instruments for French kings and the Duke of Milan. The artistic decorator for these copper engravings L. Boulengier was from the city of Albi in France, a possible key stepping-stone to the Papacy in Rome. The cathedral in Albi stood as an architectural symbol against the Cathars. Boulengier drew his inspiration from the Gothic flamboyant style of that world heritage cathedral in his home town Albi. He decorated these engravings on behalf of the powerful and art-loving Florimond de Robertet, Secretary of State for three subsequent French kings including King Francis I, 1515. Robertet was a client of Leonardo da
