Recent technological progress offers the opportunity to significantly transform conventional open surgical procedures in ways that allow minimally invasive surgery (MIS) to be accomplished by specific operative instruments’ entry into the body through key-sized holes rather than large incisions. Although MIS offers an opportunity for less trauma and quicker recovery, thereby reducing length of hospital stay and attendant costs, the complex nature of this procedure makes it difficult to master, not least because of the limited work area and constricted degree of freedom. Accordingly, this research seeks to design a Teach and Playback device that can aid surgical training by key-framing and then reproducing surgical motions. The result is an inexpensive and portable Teach and Playback laparoscopic training device that can record a trainer’s surgical motions and then play them back for trainees. Indeed, such a device could provide a training platform for surgical residents generally and would also be susceptible of many other applications for other robot-assisted tasks that might require complex motion training and control.

Over 58,000 patients suffer from renal cell carcinoma annually in the U.S. Treatment for this cancer often requires surgical removal of the cancerous tissue in a partial nephrectomy procedure. In open renal surgery, the kidney is placed on ice to increase allowable ischemia time; however, there is no widely accepted method for reducing kidney temperature during minimally invasive surgery. A device has been designed, prototyped, and evaluated to perform effective renal cooling during minimally invasive kidney surgery to reduce damage due to extended ischemia. The device is a fluid-containing bag with foldable cooling surfaces that wrap around the organ. It is deployed through a 15 mm trocar, wrapped around the kidney, and secured using bulldog clamps. The device then fills with an ice slurry and remains on the kidney for up to 20 min. The ice slurry is then removed from the device and the device is retracted from the body. Modeling results and tests of the prototype in a simulated lab environment show that the device successfully cools porcine kidneys from 37°C to 20°C in 6–20 min.

And Training

Minimally invasive surgery (MIS) is carried out using long, narrow instruments and significantly reduces trauma to the body, postoperative pain, and recovery time. Unfortunately, the restricted access conditions, limited instrument motion, and degraded sense of touch inherent in MIS result in new perceptual-motor relationships, which are unfamiliar to the surgeon and require training to overcome. Current training methods do not adequately address the needs of surgeons interested in acquiring these skills. Although a significant amount of research has been focused on the development of sensorized systems for surgery, there is still a need for a system that can be used in any training scenario (laparoscopic trainer, animal laboratories, or real surgery) for the purpose of skills assessment and training. A sensorized laparoscopic instrument has been designed that is capable of noninvasively measuring its interaction with tissue in the form of forces or torques acting in all five degrees-of-freedom (DOFs) available during MIS. Strain gauges attached to concentric shafts within the instrument allow the forces acting in different directions to be isolated. An electromagnetic tracking system is used for position tracking. Two prototypes of the sensorized instrument were constructed. Position calibration shows a maximum root mean square (RMS) error of 1.3 mm. The results of the force calibration show a maximum RMS error of 0.35 N for the actuation force, 0.07 N in the x and y directions, and 1.5 N mm for the torque calibration with good repeatability and low hysteresis. Axial measurements were significantly affected by drift, noise, and coupling leading to high errors in the readings. Novel sensorized instruments for skills assessment and training have been developed and a patent has been filed for the design and operation. The instruments measure forces and torques acting at the tip of the instrument corresponding to all five DOFs available during MIS and provide position feedback in six DOFs. The instruments are similar in shape, size, and weight to traditional laparoscopic instruments allowing them to be used in any training environment. Furthermore, replaceable tips and handles allow the instruments to be used for a variety of different tasks.

Placement Optimization

Minimally invasive surgery (MIS) requires ports to be placed through the body wall in a manner such that instruments can reach a desired area. Limitations of laparoscopic surgery include maintaining triangulation and ergonomics for the surgeon while allowing access to the anatomy with non-wristed instruments [1]. In robotically-assisted MIS, the surgeon does not stand bedside, and they have wristed instruments that the robot manipulates. Limitations of robotically-assisted MIS include range of motion (ROM) limits and decreased spatial awareness, resulting in the potential for interfering robotic components. As a result, port placement varies between laparoscopic and robotically-assisted surgery.

Novel Design

Laparoscopic surgery is a specific branch of minimally invasive surgery (MIS) that is performed on the abdomen and endoscopic tools are passed through the incision points and trocars on the abdominal wall, so they can reach the surgical site [1]. Robotic systems have been proved to be very useful as a cameraman in laparoscopic surgery; they are more stable with no fatigue and inattention and reduce the supernumerary staff required, provide excellent geometrical accuracy and improved personal control for the surgeon over the procedure, etc. The available robots for handling and control of laparoscopic lens include at least 4 actuators to fulfill the surgeon’s requirements [2]. The purpose of the present study was to develop a novel design for the laparoscope robotic arm in which while the systems move ability is maintained its active degrees of freedom are reduced.

<p>Micro robots for medical applications need to be compatible with human body, remotely controllable, smooth in movement, less painful to the patients and capable of performing the designated functions. In this paper, state of the art in the design, fabrication and control of micro robots are presented. First the benefits of micro robots in medical applications are listed out. Second, the predominantly used micro robot designs are discussed. Third, the various fabrication process used in micro robot construction are presented. Fourth, the different approaches used for its operation and control in micro robot technology are narrated. Next based on the review we have designed a swimming micro robot driven by external magnetic fields for minimally invasive surgery. The advantage of EMA is that it can generate a wireless driving force. Then, the locomotive mechanism of the micro robot using EMA is presented. Using the EMA system setup various experiments have been conducted.
