Robotic Instruments

Background and Objectives: Robotic surgery is currently at the forefront of both adult and pediatric treatment. The main limit in the wide adoption of this technology is the high cost of purchasing and running the robotic system. This report will focus on the costs assessment of running a robotic program in a pediatric surgery center in Romania. Materials and Methods: In 12 months we performed 40 robot-assisted procedures in children. We recorded and analyzed data regarding their age, gender, pathological condition and comorbidities, surgical procedure, time of surgery, complications, hospital stay and related costs, medication, robotic instruments and consumables, additional cost, and income per case received from the National Insurance Company (NIC). Results: Mean cost per case was €3260.63 (€1880.07 to €9851.78) and was influenced by type of the procedure, intraoperative incidents, postoperative complication, and non-scheduled reinterventions (p < 0.05). The direct costs for operating the surgical robot were relatively constant, regardless of the surgical procedure (mean €1579.81). The reimbursement from the NIC ranged from 5% to 56% (mean 16.9%) of the total cost per case. Conclusion: In Romania, a pediatric surgery robotic program is not cost-efficient and cannot operate relying solely onto the health insurance system.

Historically, network music has explored the practice and theory of interconnectivity, utilising the network itself as a creative instrument. The Machine Orchestra (TMO) has extended this historical idea by developing the custom software suite Signal, and creating a shared, social instrument consisting of musical robotics. Signal is a framework for musical synchronisation and data sharing, designed to support the use of musical robotics in an attempt to more fully address ideas of interconnectivity and embodied performance. Signal, in combination with musical robotics, also facilitates the exploration of interaction contexts, such as at the note level, score level and sound-processing level. In this way, TMO is simultaneously building upon the historical contributions and developing aesthetics of network music.

ObjectiveTo demonstrate a robotic-assisted psoas hitch with ureteral reimplantation.MethodsWe gleaned video footage from a robotic-assisted psoas hitch procedure performed for a patient with an isolated pelvic recurrence of ovarian cancer.ResultsWe demonstrate trocar placement and a robotic-arm docking strategy for pelvic recurrence of ovarian cancer. We also show surgical steps involved in a psoas hitch and reimplantation of a transected ureter into the bladder. Special emphasis is placed on guiding the surgeon using key robotic instruments and materials to optimize the robotic completion of this procedure. Key components of the procedure, including en bloc tumor excision and ureteral transection, are shown. The bladder is placed on traction using the fourth arm, and the avascular planes of dissection, including the space of Retzius and the paravesical spaces, are shown. The bladder is then backfilled to allow the surgeon to determine the ideal placement of the ureteral reimplantation to ensure the anastomosis is tension free. The surgeon then demonstrates where and how to place anchoring sutures from the bladder to the psoas muscle. The ureter is examined to determine where it can be implanted in the bladder with zero tension or angulation, which would compromise function and healing. The ureter is prepared for reimplantation, including trimming, tagging, and spatulation. An instrument tie technique is used to implant the ureter into the bladder and a ureteral stent is placed. Robotic-assisted psoas hitch with ureteral reimplantation has been described in the literature.1–4 ConclusionsThrough the use of still photographs and video, we demonstrate the technique of robotic-assisted psoas hitch with ureteral reimplantation.

Object. To enhance the surgeon's dexterity and maneuverability in the deep surgical field, the authors developed a master—slave microsurgical robotic system. This concept and the results of preliminary experiments are reported in this paper. Methods. The system has a master control unit, which conveys motion commands in six degrees of freedom (X, Y, and Z directions; rotation; tip flexion; and grasping) to two arms. The slave manipulator has a hanging base with an additional six degrees of freedom; it holds a motorized operating unit with two manipulators (5 mm in diameter, 18 cm in length). The accuracy of the prototype in both shallow and deep surgical fields was compared with routine freehand microsurgery. Closure of a partial arteriotomy and complete end-to-end anastomosis of the carotid artery (CA) in the deep operative field were performed in 20 Wistar rats. Three routine surgical procedures were also performed in cadavers. The accuracy of pointing with the nondominant hand in the deep surgical field was significantly improved through the use of robotics. The authors successfully closed the partial arteriotomy and completely anastomosed the rat CAs in the deep surgical field. The time needed for stitching was significantly shortened over the course of the first 10 rat experiments. The robotic instruments also moved satisfactorily in cadavers, but the manipulators still need to be smaller to fit into the narrow intracranial space. Conclusions. Computer-controlled surgical manipulation will be an important tool for neurosurgery, and preliminary experiments involving this robotic system demonstrate its promising maneuverability.
