چکیده

INTRODUCTION Conventional manual laparoscopic instruments for minimally invasive surgery have limited dexterity within the patient, making procedures challenging. Surgical robotic systems offer enhanced articulation, but at substantial financial costs. This has motivated the development of high-dexterity, low-cost laparoscopic instruments. AREAS COVERED This article reviews both commercial and academic results on creating fully mechanical (i.e. non-robotic) laparoscopic instruments that provide wrists or wrist-like dexterity within the patient. We review the state of the art in the development of these mechanical instruments, focusing on the surgeon interface, wrist mechanism, and the kinematic mapping between the two. Expert commentary: Current articulated mechanical laparoscopic instruments exhibit a wide range of designs, with no clear consensus on what makes such devices easy to use. As these technologies mature, user studies are needed to determine surgeon preferences. Articulated, low-cost instruments have the potential to impact the minimally invasive surgery market if they provide compelling benefits to surgeons.

The First Korean Experience of Telemanipulative Robot-Assisted Laparoscopic Cholecystectomy Using the da Vinci System

With the advancement of laparoscopic instruments and computer sciences, complex surgical procedures are expected to be safely performed by robot assisted telemanipulative laparoscopic surgery. The da Vinci system (Intuitive Surgical, Mountain View, CA, USA) became available at the many surgical fields. The wrist like movements of the instrument's tip, as well as 3-dimensional vision, could be e...

An articulated handle to improve the ergonomic performance of robotic dextrous instruments for laparoscopic surgery

Hand-held robotic instruments with dextrous end-effectors offer increased accessibility and gesture precision in minimally invasive laparoscopic surgery. They combine advantages of both intuitive but large, complex, and expensive telesurgery systems, and much cheaper but less user-friendly steerable mechanical instruments. However, the ergonomics of such instruments still needs to be improved i...

Dexterity and Guidance Without Automation: Surgical Robot-Like Capabilities at a Fraction of the Cost

This dissertation offers ways that the dexterity and guidance associated with imageguided robotic surgery can be delivered without automation. The overall objective is to provide highly capable instruments to surgeons, which can, in principle, be produced for a lower overall cost or with greater overall capabilities than the robotic and image guidance systems currently on the market. Of particu...

Towards the Development of a Hand-Held Surgical Robot for Laparoscopy.dvi

A minimally invasive surgery (MIS) which typically involves endoscopic camera and laparoscopic instruments may seem to be the ideal surgical procedure for its apparent benefits. However, in comparison to open surgeries, the spatial and mechanical tool limitations posed on surgeons are so high that often MIS is foregone for complex cases and even when it is possible, the procedure requires a hig...

Comparison of Control Modes of a Hand-Held Robot for Laparoscopic Surgery

Teleoperated robots for minimally invasive surgery make surgeons loose direct contact with the patient. We are developing a handheld, dexterous surgical robot that can be controlled with one hand only, while standing at the operating table. The instrument is composed of a master part (the handle) and a slave part (the tip). This work compares the performance of different control modes, i.e. dif...
