Laparoscopic surgery is very popular medical intervention for diagnoses and treatment of same abdominal diseases. The procedures are performed using long thin tools that are inserted through a trocar in the human body. The surgeon orients the instruments by laparoscopic images displayed on a monitor. Environment is uncertain (highly dynamic) with l...

Simulation-based training is used in various fields. One of these fields is medical education. This study researches the use of Augmented Reality (AR) for laparoscopic surgeries and the settings for surgical training. AR adds an overlay of computer-generated content on a camera live image. AR helps medical staff to improve diagnostics and surgical...

Trends in medical technologies are novel techniques and methods for study of biological tissue and determination of the presence of an anomaly in the tissue structure. An attempt in this direction is based on augmented reality surgical systems and devices that allow doctors to visualize data from diagnostic and surgical procedures, and improve work...

In this article is presented a device for macro-and micro-stimulation in an analysis and control of biological properties of the tissue structure. In laparoscopic surgery, it is very important to provide adequate tool tissue force information to the surgeon. This information has to be received in real-time and synchronously with the control of the...

Design principles of a novel Multifunctional Operation Station (MOS) using Augmented Reality (AR) technology (MOSAR) are proposed in this paper. AR-based design allows more ergonomic remote instrument control in real time in contrast to classical instrument-centered interfaces. Another advantage is its hierarchical software structure including mult...

Laparoscopic surgery is very popular medical intervention for diagnoses and treatment of same abdominal diseases. The task of the surgeon is to gripping, moving, and cutting of tissues, organs and execute diagnosis. The main problem which is associated with this surgical procedure is the lack of tactile sense-it is due to the specifics of the opera...

The application of laparoscopic interventions is increasing, and this leads to demands for innovative and better techniques, tools and methods for laparoscopic surgery. Robotic technologies are advancing in the field of minimally invasive surgery. The last decade, more than 1.5 million laparoscopic surgical procedures, including gynecologic, cardia...

The main target of everyone engineering work associated with minimally-invasive surgery is to provide adequate tool-tissue force information to the surgeons so that they can regain the sense of touch that has been lost through laparoscopic surgery. In this context the main objective of the work design novel family laparoscopic tools with better tec...

The article presents investigations in the area of the analysis of heterogeneous biological tissues using tools based on mechanical stimulations. Some known tissue mechanical models are presented along with one approach for specifying the tissue internal structure by measuring mechanical macro parameters of the research tools. The methodology of mi...

The article presents some methods and tools used for data processing of scientific data from direct contact of the researcher with them is impossible due to remoteness, unfavorable conditions for a person's life or technological limitations. For such objects it is typically that the researcher uses specialized intelligent electronic devices, contro...

The wireless "Integrated system for monitoring environmental parameters, managing microclimate, light-ing and energy - WMCS 100" is designed to monitor and control various parameters of technological objects (greenhouses, warehouses, dryers, refrigerators, clean rooms and others ) related the implementa-tion of production processes. Software of WMC...

A realization of wireless tools for control of mechatronic objects is presented in this article. They are based on the wireless stack uMAC and use wireless microcontrollers designed for NXP chips (JN5148 or JN5168). The control system includes two functional types of communication devices – Gateway and Controller. They are working as IEEE 802.15.4...

Laparoscopic surgery rapidly evolves as minimally invasive surgery. The lack of the tactile sense is the most important disadvantage associated with laparoscopy because it limits surgeon abilities to diagnoses and treatment some surgical problems. The introduction of robots in minimally invasive surgery will considerably enhance the accuracy of med...

This paper describes a novel mechatronic microsurgery system. There are many procedures in microsurgery (arthroscopy, laparoscopy, dental treatment) whereby the position resolution of the human hand is insufficient. In the same time the conventional surgical instruments are too bulky to be used in microsurgery. What are required to improve the pres...

The object of study in this paper is a planar slotted link mechanism for accurate positioning of the dental handpiece tool head. Kinematical and force analysis of the designed prototype is done on the basis of known links overall sizes and actuator energy source. The aim of investigation is to calculate constraint reactions and to determine necessa...
