Robotics has a significant potential to enhance the overall capacity and efficiency of healthcare systems. Robots can help surgeons perform better quality operations, leading to reductions in the hospitalisation time of patients and in the impact of surgery on their postoperative quality of life. In particular, robotics can have a significant impact on microsurgery, which presents stringent requirements for superhuman precision and control of the surgical tools. Microsurgery is, in fact, expected to gain importance in a growing range of surgical specialties as novel technologies progressively enable the detection, diagnosis and treatment of diseases at earlier stages...

Of all patients who have vasectomies performed in the United States, upwards of 6% will pursue a vasectomy reversal. Currently, the gold-standard reversal procedure is a microscopic vasovasostomy utilizing either a one or two-layer vasal anastomosis. Unfortunately, most urologists do not perform these procedures as they require extensive training and experience in microsurgery. The objective of our study was to evaluate the feasibility and success rate of robot-assisted vasovasostomy performed at our institution...

The objective of this systematic review is to synthesize the best available evidence regarding the oncological and survival outcomes (as measured by disease control, disease-free survival, disease-specific survival and overall survival) of transoral robotic surgery (TORS) versus transoral laser microsurgery (TLM) in the treatment of oropharyngeal squamous cell carcinoma in adults (aged 18 years or older). Specifically the review questions are:1 Is there a difference in oncological outcomes between a traditional "Halstedian" en bloc tumor resection technique used in TORS versus a modern segmental tumor dissection technique used in TLM?2 Does one surgical approach confer better oncological outcomes with respect to a particular patient subgroup, such as patients with a positive human papilloma virus status or patient's with different tumor T-stages?...

Herein, we described a novel method as the use of AcuBlade robotic microsurgery system to manage idiopathic subglottic stenosis in a 73 years old lady. Compared to traditional CO2 lasers, AcuBlade facilitated the scar resection by the generation of different shape of beams (straight, curved, or disk). The same setting used for phonomicrosurgery (1-mm beam length, power of 10 W and pulse duration of 0.05-s) allowed to obtain fast, long, and uniform cuts. In addition, the reduction of the number of laser passes over the same area prevented injury of adjacent tissue and thus reduced the risk of recurrence...

Surgical treatment of laryngeal cancer has been established for decades. In addition to total laryngectomy, which was first performed in 1873, a large number of organ preservation surgical techniques, like open partial laryngectomy, transoral laser microsurgery and transoral robotic surgery, have been developed. Studies on laryngeal cancer surgery are mainly retrospective case series and cohort studies. The evolution of chemoradiation protocols and their analysis in prospective randomized trials have led to an increasing acceptance of non-surgical treatment procedures...

In retinal microsurgery, membrane peeling is a standard procedure requiring the delamination of a thin fibrous membrane adherent to the retina surface by applying very small forces. Robotic devices with combined force-sensing instruments have significant potential to assist this procedure by facilitating membrane delamination through induced micro-vibrations. However, defining the optimal frequency and amplitude for generating such vibrations, and updating these parameters during the procedure is not trivial...

BACKGROUND: Microsurgery can be challenging secondary to orientation of the vessels, accessibility, or depth of the wound. Robotically assisted microsurgery reduces tremors and improves visualization and may improve the quality of anastomosis compared with traditional microsurgery. The purpose of this study was to compare robotically assisted microsurgery to traditional microsurgery in technically challenging situations with respect to time of anastomosis, quality of anastomosis, and Objective Structured Assessment of Technical Skills...

The operative microscope has been a staple instrument in the neurosurgical operating room over the last 50 years. With advances in optoelectronics, options such as robotically controlled high magnification have become available. Such robotically controlled optoelectronic systems may offer new opportunities in surgical technique and teaching. However, traditionally trained surgeons may find it hard to accept newer technologies due to an inherent bias emerging from their previous background. We, therefore, studied how a medically naïve population in a pilot study would meet set microsurgical goals in a cadaver experiment using either a conventional operative microscope or BrightMatter™ Servo system, ​a robotically controlled optoelectronic system (Synaptive Medical, Toronto, Ontario, Canada)...

REVIEW
Vinay Rai, Nitin Mishra
A transanal approach to rectal polyp and cancer excision is often an appropriate alternative to conventional rectal resection, and has a lower associated morbidity. There has been a steady evolution in the techniques of transanal surgery over the past 30 years. It started with traditional transanal excision and was revolutionized by introduction of transanal endoscopic microsurgery in early 1980s. Introduction of transanal minimally invasive surgery made it more accessible to surgeons around the world. Now robotic platforms are being tried in certain institutions...

Microanastomosis is a microsurgical gesture that involves suturing two very small blood vessels together. This gesture is used in many operations such as avulsed member auto-grafting, pediatric surgery, reconstructive surgery - including breast reconstruction by free flap. When vessels have diameters smaller than one millimeter, hand tremors make movements difficult to control. This paper introduces our preliminary steps towards robotic assistance for helping surgeons to perform microanastomosis in optimal conditions, in order to increase gesture quality and reliability even on smaller diameters...

Micron is a fully handheld active micromanipulator that helps to improve position accuracy and precision in microsurgery by cancelling hand tremor. This work describes adaptation, tuning, and testing of the Micron system for stapedotomy, a microsurgical procedure performed in the middle ear to restore hearing that requires accurate manipulation in narrow spaces. Two end-effectors, a handle, and a brace (or rest) were designed and prototyped. The control system was adapted for the new hardware. The system was tested ex vivo in stapedotomy procedure comparing manually-performed and Micron-assisted surgical tasks...

In retinal surgery, microsurgical instruments such as micro forceps, scissors and picks are inserted through the eye wall via sclerotomies. A handheld intraocular light source is typically used to visualize the tools during the procedure. Retinal surgery requires precise and stable tool maneuvers as the surgical targets are micro scale, fragile and critical to function. Retinal surgeons typically control an active surgical tool with one hand and an illumination source with the other. In this paper, we present a "smart" light pipe that enables true bimanual surgery via utilization of an active, robot-assisted source of targeted illumination...

Bony free flap reconstruction of the facial skeleton remains a challenging area of reconstructive surgery. Despite technological advances that have aided planning and execution of these procedures, surgical inaccuracy is not insignificant. One source of error that has not been wholly addressed is that attributable to a human operator. In this study, we investigate the feasibility and accuracy of performing osteotomies robotically in pre-programmed fashion for fibula free flap mandible reconstruction as a method to reduce inaccuracies related to human error...
