Traumatic Memory

Traumatic Memory

Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Post-traumatic Stress Disorder

Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Epigenetic Regulation

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Ribosomal RNA Synthesis

Ribosomal RNA Synthesis

Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Area of Science:

Robotics
Minimally Invasive Surgery
Surgical Technology

Background:

Current laparoscopic surgery robots, like the da Vinci system, lack crucial force feedback, limiting surgeon tactile sensation.
This limitation can hinder precise control and potentially impact patient safety during complex procedures.

Purpose of the Study:

To design and validate a novel minimally invasive laparoscopic surgery robot system incorporating multi-dimensional force feedback.
To introduce a force feedback-based safety protection strategy for enhanced surgical operations.

Main Methods:

Development of a new surgical robot system featuring a master console, stereo vision, and a slave surgical cart.
Integration of multi-dimensional instrument force feedback technology and a safety protection strategy.
Conducting live pig experiments to evaluate the system's performance.

Main Results:

The designed robot system successfully implemented full-state operation force sensing capabilities.
Live pig experiments demonstrated significantly reduced bleeding compared to existing surgical robot data.
The force feedback and safety protection strategies were effectively validated.

Conclusions:

The novel laparoscopic surgery robot system addresses the limitations of current technologies by providing essential force feedback.
The integrated safety features and force sensing enhance surgical precision and patient safety.
Experimental results confirm the system's potential to improve outcomes in minimally invasive surgery.
