Special Instrumentation

Currently, there is a great interest in the use of minimally invasive surgery methods. Such surgeries require special instrumentation. Doctors increasingly use medical robots that replace assistants responsible for setting the position and orientation of the endoscope (vision), as well as make it possible to control surgical instruments. One of very promising fields of expansion of this technology is veterinary medicine. This article presents a review of literature on animal laparoscopic surgery with the use of medical robots. Particular attention was paid to animal experiments involving the Robin Heart family robots. Moreover, the article presents the construction and principle of operation of the smallest manipulator of the Robin Heart family, as well as describes preliminary simulations of surgery with the use of this robot. In the conclusion, possible directions for further improvement and implementation of the Robin Heart robot have been formulated.

Abstract Background The purpose of this study was to investigate the clinical effect of minimally invasive surgery for inguinal cryptorchidism. Methods The patients were divided into the minimally invasive surgery group (n = 100) and the traditional surgery group (n = 58). In the minimally invasive surgery group, patients with low inguinal cryptorchidism (n = 54) underwent surgery with a transscrotal incision, and patients with high inguinal cryptorchidism (n = 46) underwent laparoscopic surgery. Results There was no difference in the hospital stay duration or cost between the minimally invasive surgery group and the traditional surgery group (P > 0.05). As for the operative time, minimally invasive surgery of low inguinal cryptorchidism was shorter than traditional surgery (P = 0.033), while minimally invasive surgery of high inguinal cryptorchidism was comparable to traditional surgery (P = 0.658). Additionally, there were no cases of testicular atrophy, testicular retraction, inguinal hernia or hydrocele in either group. There was no significant difference in the incidence of poor wound healing between the two groups (P > 0.05). Although there was no significant difference in the incidence of scrotal hematoma between the two groups (P > 0.05), the incidence in the minimally invasive surgery group was higher than that in the traditional surgery group. Conclusions Minimally invasive surgery including a transscrotal incision for low inguinal cryptorchidism and laparoscopic surgery for high inguinal cryptorchidism is as safe and effective as traditional surgery, and could also provide a good cosmetic effect for children.

Inverse Kinematics Problem

A crucial design challenge in minimally invasive surgical (MIS) robots is the provision of a fully decoupled four degrees-of-freedom (4-DOF) remote center-of-motion (RCM) for surgical instruments. In this paper, we present a new parallel manipulator that can generate a 4-DOF RCM over its end-effector and these four DOFs are fully decoupled, i.e., each of them can be independently controlled by one corresponding actuated joint. First, we revisit the remote center-of-motion for MIS robots and introduce a projective displacement representation for coping with this special kinematics. Next, we present the proposed new parallel manipulator structure and study its geometry and motion decouplebility. Accordingly, we solve the inverse kinematics problem by taking the advantage of motion decouplebility. Then, via the screw system approach, we carry out the Jacobian analysis for the manipulator, by which the singular configurations are identified. Finally, we analyze the reachable and collision-free workspaces of the proposed manipulator and conclude the feasibility of this manipulator for the application in minimally invasive surgery.

Safety Considerations

Laparoscopy or minimally invasive surgery requires surgeons to attain proficiency in skills that are fundamentally different to those required for open surgery. As a result, it both challenges junior trainees and surgeons who are experienced in open surgery. Not surprisingly, the initial learning phase of laparoscopy has been associated with an increased incidence of serious complications. Owing to time constraints and the ethical and safety considerations of allowing novices to perform laparoscopic surgery on patients, alternative methods have been sought to train junior surgeons on the basics of laparoscopic surgery.

Purpose Robot-assisted system for minimally invasive surgery (MIS) has been attracting more and more attentions. Compared with a traditional MIS, the robot-assisted system for MIS is able to overcome or reduce defects, such as poor hand-eye coordination, heavy labour intensity and limited motion of the instrument. The purpose of this paper is to design a novel robotic system for MIS applications. Design/methodology/approach A robotic system with three separate slave arms for MIS has been designed. In the proposed robot, a new mechanism was designed as the remote centre motion (RCM) mechanism to restrain the movement of instrument or laparoscope around the incision. Moreover, an improved instrument without coupling motion between wrist and grippers was developed to enhance its manipulability. A control system architecture was also developed, and an intuitive control method was applied to realize hand-eye coordination of the operator. Findings For the RCM mechanism, the workspace was analyzed and the positioning accuracy of the remote centre point was tested. The results show that the RCM mechanism can be applied to MIS. Furthermore, the master-slave trajectory tracking experiments reveal that slave robots are able to follow the movement of the master manipulators well. Finally, the feasibility of the robot-assisted system for MIS is proved by performing animal experiments successfully. Originality/value This paper offers a novel robotic system for MIS. It can accomplish the anticipated results.

Basic Set

The field of minimally invasive surgery has evolved rapidly since the first laparoscopic appendectomies and cholecystectomies were performed nearly 30 years ago.1 Minimally invasive approaches are now widely used for gastrointestinal resection, hernia repair, antireflux surgery, bariatric surgery, and solid-organ surgery, such as hepatic, pancreatic, adrenal, and renal resections. Although the techniques and equipment needed to access, expose, and dissect vary according to the type of operation and surgeon’s preference, a basic set of equipment is essential for any laparoscopic or robotic procedure: endoscope, camera, light source, signal processing unit, video monitor, insufflator and gas supply, trocars, and surgical instruments. Understanding how to use and troubleshoot this equipment is critical for any surgeon who performs minimally invasive surgery. We review the essentials of basic laparoscopic equipment, including the mechanics of normally functioning equipment and the various types of laparoscopic trocars and instruments. We also discuss robotic equipment and the fundamental differences from laparoscopy. Minilaparoscopy and single-site equipment are briefly explained. Additionally, we discuss potential technical difficulties that surgeons may encounter while performing minimally invasive procedures and provide suggestions for troubleshooting these problems.

Robots are wide across used in several industrial applications. Robot applications are more found in medical industry in recent days. In initial days, robots were mostly used for simple surgeries and medical applications such as laparoscopic surgery and minimally invasive surgery in 1980's. At that time robotic surgeries were performed with the presence of surgeons in operation theatre. The present day technology has been so much advanced with more enhanced capabilities to perform several complicated tasks such as remote surgery and micro robotic surgery. The current paper discuss about the history and evolution of robots in medical industry and their latest technological advances, applications in various fields in medicine and limitations of robots in medical industry along with its future scope.

Abstract Background Crohn’s disease (CD) is an inflammatory bowel condition that still requires surgical intervention in about 70% of cases with laparoscopic surgery increasingly becoming the preferred approach. We present our experience in laparoscopic and open surgery for luminal CD in a DGH setting. Methods This was a retrospective analysis of data collected prospectively between 2008 and 2018. All patients with the diagnosis of CD who underwent a surgical intervention for luminal CD were selected and their demographic, clinical and surgical outcomes data analysed. Results 183 patients were identified. 162 (87%) underwent open and 21 (13%) laparoscopic surgery (p < 0.0001). The median age was 48 years (16–82 years) in the open group and 42 years (16–64 years) in the laparoscopic group(p = 0.05). Male:female ratio was 1:1.2 in the open and 1:1 in the laparoscopic groups. Anastomotic leak rates were lower in the laparoscopic group (0% vs. 2.5%, p = 0.3520). Statistically significant lower readmission rates (9.5% in the laparoscopic, 18% in the open groups, p = 0.0255) and reoperation rates (14% in the laparoscopic and 18% in the open groups, p = 0.0108) were noted in the laparoscopic group. Conclusion Laparoscopic surgery is safe in patients requiring surgical intervention for Crohn’s disease with a notable trend towards improved clinical outcomes.
