Aquablation is a minimally invasive surgical technology for benign prostate enlargement, which uses high-pressure saline to remove parenchymal tissue through a heat-free mechanism of hydrodissection. Early results show this to be a promising surgical strategy with a strong morbidity profile and reduced resection time. This review serves to provide an overview of the technique and evaluate its safety and efficacy.

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.

The single-port gasless laparoscopic surgical instrument is an international leading patented product in minimally invasive surgery. This paper first describes the composition and the usage of the shadowless retractor of the single-port gasless laparoscopy minimally invasive surgical instrument. Aim to meet the specific requirement arise in the minimally invasive surgery for the animal abdominal cavity, we first improve the existing shadowless lifting retractor. Then, this paper proposes and designs the double-light shadowless lifting retractor. The test has shown the designed double-light shadowless lifting retractor has satisfied the design requirement. The practical tests have been done and shown the viability and effectiveness of the proposed design approach.

We have developed a telemedicine project called Telesurgex, which is an integrated information system designed for several hospitals as well as the Minimally Invasive Surgery Centre. The project researches and develops telemedicine systems (both hardware and software) and their contents, ensuring that they are really useful and not just a videoconference with medical topics. Another aim of the project is the improvement of teleteaching systems as applied to medicine, mainly teleteaching of minimally invasive surgical techniques.

Object Adult degenerative scoliosis can be a cause of intractable pain, decreased mobility, and reduced quality of life. Surgical correction of this problem frequently leads to substantial clinical improvement, but advanced age, medical comorbidities, osteoporosis, and the rigidity of the spine result in high surgical complication rates. Minimally invasive surgery is being applied to this patient population in an effort to reduce the high complication rates associated with adult deformity surgery. Methods A retrospective study of 23 patients was undertaken to assess the clinical and radiographic results with minimally invasive surgery for adult thoracolumbar deformity surgery. All patients underwent a lateral interbody fusion followed by posterior percutaneous screw fixation and possible minimally invasive surgical transforaminal lumbar interbody fusion if fusion near the lumbosacral junction was necessary. A mean of 3.7 intersegmental levels were treated (range 2–7 levels). The mean follow-up was 13.4 months. Results The mean preoperative Cobb angle was 31.4°, and it was corrected to 11.5° at follow-up. The mean blood loss was 477 ml, and the operative time was 401 minutes. The mean visual analog scale score improvement for axial pain was 3.96. Clear evidence of fusion was seen on radiographs at 84 of 86 treated levels, with no interbody pseudarthroses. Complications included 2 returns to the operating room, one for CSF leakage and the other for hardware pullout. There were no wound infections, pneumonia, deep venous thrombosis, or new neurological deficits. However, of all patients, 30.4% experienced new thigh numbness, dysesthesias, pain, or weakness, and in one patient these new symptoms were persistent. Conclusions The minimally invasive surgical treatment of adult deformities is a promising method for reducing surgical morbidity. Numerous challenges exist, as the surgical technique does not yet allow for all correction maneuvers used in open surgery. However, as the techniques are advanced, the applicability of minimally invasive surgery for this population will likely be expanded and will afford the opportunity for reduced complications.

Minimally invasive surgery has changed the landscape of women’s surgical healthcare. Conventional and robotic laparoscopy are the preferred approach for many major minimally invasive gynecological procedures. However, the philosophy of minimally invasive surgery has been pushed to reduce the size and minimize the number of ports placed. Many conventional minimally invasive surgical procedures use 3–5 ports through multiple small incisions. Laparoscopic single site surgery tries to perform on that philosophy but has its limitations. Enters robotic surgery already a major force in minimally invasive surgery and now sets to remove the limitations of single site surgery. However it requires proper understanding of the instruments and the techniques for successful robotic single site surgery. It starts with patient selection. Knowing the instruments needed and the proper set up of those instruments. Then knowing how to use the instruments in operating and suturing and closing. And finish with special considerations.

The aim of the research is to study the results of minimally invasive surgery for the treatment of nonspecifi c infectious spine lesions, and to present personal experience. Material and methods. Three patients with purulent nonspecifi c spondylodiscitis of lumbar spine got minimally invasive surgical treatment. The essence of surgical intervention included X-ray-assisted placement of tubular retractors in the area of intervertebral disc aff ected by purulent process; debridement and irrigation with antiseptic solution of interbody space, and setting a drain tube. All patients were treated during the period from December 2016 to February 2019. They were examined before surgery and in 3 months aft er the discharge. Laboratory parameters (CBT, C-reactive protein, bacteriological analysis of intervertebral disc contents) and instrumental research methods (computer tomography, magnetic resonance imaging) were evaluated. ODI, VAS, SF-36 questionnaires helped to assess pain syndrome and life quality of patients. Results. In 100 % of studied cases infection was caused by Staphylococcus aureus. The result of treatment in all cases was assessed as good, because pain syndrome, neurological disorders and inflammatory process were arrested; there were no signs of disease progression. In all cases, life quality of patients was restored. In one case, additional surgical intervention was required (posterior instrumental fi xation of spine) because of instability signs. Conclusion. Minimally invasive surgical treatment of purulent single-level spondylodiscites can be recommended for practical use. The use of such approache allows to verify purulent infection agent, to damage soft tissues less getting proper sanitation of interbody space. It also allows to stop the infection and restore life quality of a patient

Minimally invasive techniques in thoracic surgery have made great progress over the past 20 years and are still evolving. Many surgical procedures performed with large thoracotomy incisions in the past can now be performed with much smaller incisions. With many studies, the advantages of minimally invasive surgery have been clearly seen, and thus its use has become widespread worldwide. Today, minimally invasive surgical methods have become the first choice in the diagnosis and treatment of lung, pleural and mediastinal pathologies. Minimally invasive approaches in thoracic surgery include many different techniques and applications. In this chapter, current minimally invasive techniques in thoracic surgery are discussed and important points are emphasized in the light of the current literature.
