Chinese Journal of Medical Instrumentation 2014;38(1):47-49
Da Vinci robotic surgical system leads the development of minimally invasive surgical techniques. By using Da Vinci surgical robot for minimally invasive surgery, it brings a lot of advantages to the surgeons. Since 2008, Da Vinci surgeries have been performed in 14 hospitals in domestic cities such as Beijing and Shanghai. Until the end of 2012, 3 551 cases of Da Vinci robotic surgery have been performed, covering various procedures of various surgical departments including the department of general surgery, urology, cardiovascular surgery, thoracic surgery, gynecology, and etc. Robotic surgical technique has made remarkable achievements.

At present, there still exist some limitations in the laparoscopic surgery robot represented by da Vinci surgical robot, such as the lack of force feedback function. Doctor can not feel the force feedback while operating. In this paper, a new minimally invasive laparoscopic surgery robot system is designed. Based on the master side surgeon's console, stereo vision subsystem and the slave side surgical cart, the multi-dimensional instrument force feedback technology and force feedback based safety protection strategy are introduced. The design realizes the force sensing function of full state operation. Besides, a number of different live pig experiments are carried out. The amount of bleeding in these experiments is relatively small compared with the data of the same kind of surgical robots, which effectively validates the force feedback and surgical safety protection strategies of the new robot system.

OBJECTIVETo verify the feasibility and safety of the vascular interventional vascular interventional surgical robot system applied to vascular interventional operation.
METHODSFrom March to September 2013, 10 patients had undergone robot-assisted cerebral angiography. There were 6 male and 4 female patients; aged from 19 to 58 years, with an average age of 38.4 years. The operation were carried out by neurosurgeons and vascular interventional robot. After successfully implanted of femoral artery sheath by hand, the catheter was fixed on the robot, under the guidance of navigation image the surgeon manipulate the master part and control the slave part of robot by sending command through network transmission, finally finished the whole cerebral angiography. The operation time was recorded from placing the sheath into femoral artery to finishing cerebrovascular selective angiography, simultaneously the time of staff under exposure of X ray was recorded, and the position difference between the setted targets and the actual position(positioning accuracy).
RESULTSIt took 25-41 minutes to finish the cerebral angiography, the average time was (31 ± 5) minutes, and the robot-assisted angiography went quickly and smoothly without surgical complications. The remote positioning accuracy was (1.03 ± 0.23) mm. The time of staff under exposure of X ray was 0 minute, the entire experimental process was basically implemented mechanization and automation.
CONCLUSIONThis system basically achieves initial medical purposes, such as reducing the radiation, facilitating interventional procedures on the basis of enhancing the image navigation, shorting the operation time, and improve the quality of operation.

INTRODUCTIONThe use of robotics in total knee arthroplasty (TKA) has been shown to minimise human error, as well as improve the accuracy and precision of component implantation and mechanical axis alignment. The present study aimed to demonstrate that robot-assisted TKA using ROBODOC® is safe and capable of producing a consistent and accurate postoperative mechanical axis.
METHODSWe prospectively recruited 27 consecutive patients who underwent robot-assisted TKA between May and December 2012. Two patients were excluded from the study due to intraoperative technical problems with the robot. Long-leg radiography and computed tomography were performed prior to surgery, and used for mechanical axis measurements and component sizing. DigiMatch™ ROBODOC® Surgical System software version 4.3.6 (Curexo Technology Corp, Fremont, CA, USA) was used in all cases to perform bone cuts in accordance with the preoperative plan.
RESULTSThe postoperative coronal mechanical alignment was within 3 degrees, with a mean alignment of -0.4 ± 1.7 degrees, confirming the accuracy of the preoperative surgical plan and bone cuts. The mean operating time was 96 ± 15 min, and preoperative planning yielded 100% implant sizing accuracy.
CONCLUSIONRobotics has the potential to enable surgeons to consistently attain ideal postoperative alignment. The use of bone movement monitors and an integrated navigation system enhances the safety profile of ROBODOC® by minimising errors. However, the role of the surgeon in TKA is still vital, as the surgeon is ultimately in charge of planning the surgery, its execution and ensuring soft tissue balance during TKA.

OBJECTIVE: This study reports our initial experience of robotic high para-aortic lymph node dissection (PALND) with high port placement using same port for pelvic surgery in cervical and endometrial cancer patients. METHODS: Between July 2013 and January 2014, we performed robotic high PALND up to the left renal vein during staging surgeries. With high port placement and same port usage for pelvic surgery, high PALND was successfully performed without repositioning the robotic column. All data were registered consecutively and analyzed retrospectively. RESULTS: All patients successfully underwent robotic high PALND, followed by hysterectomy and pelvic lymph node dissection. Median age was 45 years (range, 39 to 51 years) and median body mass index was 22 kg/m2 (range, 19.3 to 23.1 kg/m2). Median operative time for right PALND and left PALND was 37 minutes (range, 22 to 65 minutes) and 44 minutes (range, 36 to 50 minutes), respectively. Median number of right and left para-aortic lymph node by pathologic report was 12 (range, 8 to 15) and 13 (range, 5 to 26). CONCLUSION: With high port placement and one assistant port, robotic high PALND with the same port used in pelvic surgery is feasible to non-obese patients.

With the rapid advancement of minimally invasive new technology, laparoscopic surgery and robotic surgery are now regarded as the main direction in surgical treatment for stomach cancers. Recent evidence has confirmed the safety and feasibility of laparoscopic surgery for early gastric cancer and advanced gastric cancer. However, gastrointestinal surgeons should pay more attention to complications after laparoscopic gastrectomy because of rich blood supply, complex tissue layers and lymph node metastasis. Common complications related to laparoscopic surgery are associated with laparoscopic instruments and operating, intra-abdominal bleeding, anastomotic leakage, anastomotic bleeding, pancreatic leakage, duodenal stump leakage, lymphatic leakage and so on. This article mainly focuses on the causes, prevention and treatment of the complications after laparoscopic gastrectomy.

8.Era of enhanced recovery after surgery and robotic gastric cancer surgery.
Chinese Journal of Gastrointestinal Surgery 2017;20(5):495-499
Enhanced recovery after surgery (ERAS) has been rapidly developing by combining several techniques with evidence-based adjustments, including preoperative education, preoperative carbohydrate loading, epidural or regional anesthesia, early initiation of enteral nutrition, ambulation and multi-modal pain management. The core part of ERAS is to reduce and reverse surgical stress and therefore greatly improve clinical outcome. Under the guidance of ERAS, perioperative management of robotic gastric cancer operation should follow the basic principles of ERAS and clinical pathway to maximize the advantages of the robotic surgery. ERAS protocol is safe and feasible for patients undergoing robotic radical gastrectomy and it can reduce surgical stress, shorten hospital stay, improve quality of life and does not increase complications, whose mechanism may be associated with the reduction of inflammation and insulin resistance, the decrease of resting energy exposure, and the protection of mitochondria function. It is worth emphasizing that it is very important to fully understand the changes of pathophysiology during perioperative period, to strictly implement the ERAS pathway based on optimized evidence-based medicine, to cooperate closely with the multidisciplinary team, to observe and manage the postoperative complications dynamically by systemic classification. The improvement of ERAS program on the outcome of patients should be summarized regularly and the new interventional strategies should be evaluated further according to the international standard.
