An Actuated Variable-View Rigid Scope System to Assist Visualization in Diagnostic Procedures.

Objective: Variable-view rigid scopes offer advantages compared to traditional angled laparoscopes for examining a diagnostic site. However, altering the scope's view requires a high level of dexterity and understanding of spatial orientation. This requires an intuitive mechanism to allow an operator to easily understand the anatomical surroundings and smoothly adjust the scope's focus during diagnosis.

A generic scope actuation system for flexible endoscopes.

Background: A scope actuation system assists a surgeon in steering a scope for navigating an operative field during an interventional or diagnostic procedure. Each system is tailored for a specific surgical procedure. The development of a generic scope actuation system could assist various laparoscopic and endoscopic procedures.

User interfaces for actuated scope maneuvering in surgical systems: a scoping review.

Background: A variety of human computer interfaces are used by robotic surgical systems to control and actuate camera scopes during minimally invasive surgery. The purpose of this review is to examine the different user interfaces used in both commercial systems and research prototypes.

Methods: A comprehensive scoping review of scientific literature was conducted using PubMed and IEEE Xplore databases to identify user interfaces used in commercial products and research prototypes of robotic surgical systems and robotic scope holders.

Scope actuation system for articulated laparoscopes.

Background: An articulated laparoscope comprises a rigid shaft with an articulated distal end to change the viewing direction. The articulation provides improved navigation of the operating field in confined spaces. Furthermore, incorporation of an actuation system tends to enhance the control of an articulated laparoscope.

Elemental composition in rainbow trout tissues from a fish farm from Patagonia, Argentina.

Rainbow trout is a salmonid specie of commercial importance raised in hatcheries in many countries. Studies over mineral requirements have being perform to guarantee the fulfillment of the nutritional needs and therefore improving the fish farm productions. The aim of this work was to investigate the performance of the elements like Ag, As, Br, Ca, Cr, Cs, Fe, Hg, K, Na, Rb, Se, and Zn, in rainbow trout from a Patagonian fish farming.
